[PMID: 39824744 DOI: 10.1016/j.jpedsurg.2024.162150] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2024] [Revised: 12/04/2024] [Accepted: 12/30/2024] [Indexed: 01/20/2025]
Abstract
OBJECTIVE Magnetic anastomosis is an innovative technique for establishing esophageal continuity in infants born with esophageal atresia. Few case series featuring this technology have been published, with even fewer reports on complications. We present the entire Canadian experience with this approach. METHODS A nationwide retrospective review of all esophageal atresia patients treated with magnetic anastomoses in Canada was conducted through the Canadian Consortium for Research in Pediatric Surgery (CanCORPS). RESULTS Magnetic anastomoses were attempted in nine patients including four Type A, two Type B, and three Type C. The median pre-operative esophageal gap was 2.9 cm (range 0.0-5.5 cm). In four patients, magnetic anastomosis was used as a salvage technique, after failed attempted primary repair. Seven patients (78 %) achieved esophageal patency after magnet insertion. Strictures developed in all successful cases and required a median of 10 dilatations (range 3-16). In one patient with a failed anastomosis, the proximal magnet perforated the proximal esophageal pouch, while in the second case, the magnets failed to couple together. One patient had an anastomosis form but required operative intervention shortly afterwards to both revise the anastomosis and address a missed proximal fistula. CONCLUSION In the Canadian experience, magnetic anastomosis was successful in establishing esophageal continuity in most patients. However, all patients developed strictures requiring multiple dilatations, and there was a substantial risk of complications requiring additional operative procedures. Further refinement of this technique may establish magnetic anastomosis as another tool for the pediatric surgeon treating long-gap and other challenging cases of esophageal atresia.

Abstract
Magnetism, recognized in ancient Greece and China, is a fundamental physical force influencing numerous domains, including medicine and surgery. Historically, the medical use of magnets dates back over two millennia. As proof, the ancient Sanskrit medical textbook Sushruta Samhita describes the removal of a metallic arrow lodged in the flesh with a magnet. Modern uses span from diagnostic to therapeutic applications, including in paediatric surgery. High-field magnetism, utilized in Magnetic Resonance Imaging and Transcranial Magnetic Stimulation (TMS), shows promise for various medical conditions, including depression and neurodegenerative diseases. Despite controversy surrounding low-field magnetism, its potential remains a topic of interest. One of the applications in paediatric surgery that has been evaluated in a randomized controlled trial is magnetic acupuncture for supplementary treatment of postoperative pain. As most paediatric surgeons are well aware, the use of magnets also poses risks, particularly in children, where ingested magnets can cause severe gastrointestinal complications. Regulations have tightened in response to increasing cases of magnet ingestion-related injuries but more needs to be done to avoid injury. Currently, magnets play crucial roles in a variety of medical applications, including magnetic cell sorting and therapeutic devices. Notably, magnetic compression anastomosis, which uses magnets to facilitate luminal tissue joining, have seen significant advancements. Innovations include devices for oesophageal atresia repair, with recent studies showing promising results in animal models and early clinical trials. Future research should focus on optimizing magnetic devices, expanding their applications, and ensuring safety. The continued exploration of magnetism's effects on living tissues and the development of new magnetic technologies could revolutionize medical and surgical practices, particularly in paediatric care.

Abstract
PURPOSE OF REVIEW Esophageal atresia/tracheoesophageal fistula (EA/TEF) causes gastrointestinal (GI) complications that can begin in infancy and extend into adulthood. The etiology of these is frequently multifactorial, and they can adversely affect feeding, growth, respiratory health, and overall quality of life. This review highlights the importance of early diagnosis, multidisciplinary surveillance, and individualized treatment strategies to effectively manage these complications and improve long-term outcomes for affected children. RECENT FINDINGS Recent studies have focused on the development of evidence-based surveillance protocols to optimally manage the numerous observed EA/TEF-associated digestive complications. Many of these complications stem from the combination of gastroesophageal dysmotility and mechanical obstruction inherent to EA/TEF and its surgical management, and include gastroesophageal reflux disease, feeding difficulties, dysphagia, eosinophilic esophagitis, and pulmonary consequences of aspiration. Management of GI complications in children with EA/TEF requires careful, multidisciplinary evaluation and treatment, incorporating dietary modifications, feeding therapy, pharmacotherapy, and surgical and endoscopic interventions.

Abstract
Magnetic compression anastomosis (MCA) is a new method that provides sutureless passage construction for tubular organs. Due to the high recurrence rate of conventional endoscopic treatment and the high morbidity and mortality of surgical procedures, the MCA technique shows promise. The aim of this review is to comprehensively examine the literature related to the use of MCA in different gastrointestinal diseases over the past few years, categorizing them according to the anastomotic site and describing in detail the various methods of magnet delivery and the clinical outcomes of MCA. MCA is an innovative technique, and its use represents an advancement in the field of minimally invasive interventions. Comparison studies have shown that the anastomosis formed by MCA is comparable to or better than surgical sutures in terms of general appearance and histology. Although most of the current research has involved animal studies or studies with small populations, the safety and feasibility of MCA have been preliminarily demonstrated. Large prospective studies involving populations are still needed to guarantee the security of MCA. For technologies that have been initially used in clinical settings, effective measures should also be implemented to identify, even prevent, complications. Furthermore, specific commercial magnets must be created and optimized in this emerging area.

Abstract
Historically, children afflicted with long gap esophageal atresia (LGEA) had few options, either esophageal replacement or a life of gastrostomy feeds. In 1997, John Foker from Minnesota revolutionized the treatment of LGEA. His new procedure focused on "traction-induced growth" when the proximal and distal esophageal segments were too far apart for primary repair. Foker's approach involved placement of pledgeted sutures on both esophageal pouches connected to an externalized traction system which could be serially tightened, allowing for tension-induced esophageal growth and a delayed primary repair. Despite its potential, the Foker process was received with criticism and disbelief, and to this day, controversy remains regarding its mechanism of action - esophageal growth versus stretch. Nonetheless, early adopters such as Rusty Jennings of Boston embraced Foker's central principle that "one's own esophagus is best" and was instrumental to the implementation and rise in popularity of the Foker process. The downstream effects of this emphasis on esophageal preservation would uncover the need for a focused yet multidisciplinary approach to the many challenges that EA children face beyond "just the esophagus", leading to the first Esophageal and Airway Treatment Center for children. Consequently, the development of new techniques for the multidimensional care of the LGEA child evolved such as the posterior tracheopexy for associated tracheomalacia, the supercharged jejunal interposition, as well as minimally invasive internalized esophageal traction systems. We recognize the work of Foker and Jennings as key catalysts of an era of esophageal preservation and multidisciplinary care of children with EA.

Abstract
INTRODUCTION Delayed primary repair of esophageal atresia in patients with high-risk physiologic and anatomic comorbidities remains a daunting challenge with an increased risk for peri-operative morbidity and mortality via conventional repair. The Connect-EA device facilitates the endoscopic creation of a secure esophageal anastomosis. This follow-up study reports our long-term outcomes with the novel esophageal magnetic compression anastomosis (EMCA) Connect-EA device for EA repair, as well as lessons learned from the ten first-in-human cases. We propose an algorithm to maximize the advantages of the device for EA repair. METHODS Under compassionate use approval, from June 2019 to December 2022, ten patients with prohibitive surgical or medical risk factors underwent attempted EMCA with this device. All patients underwent prior gastrostomy, tracheoesophageal fistula ligation (if necessary), and demonstrated pouch apposition prior to EMCA. RESULTS Successful device deployment and EMCA formation were achieved in nine patients (90%). Mean time to anastomosis formation was 8 days (range 5-14) and the device was retrieved endoscopically in five (56%) cases. At median follow-up of 22 months (range 4-45), seven patients (78%) are tolerating oral nutrition. Balloon dilations (median 4, range 1-11) were performed either prophylactically for radiographic asymptomatic anastomotic narrowing (n = 7, 78%) or to treat clinically-significant anastomotic narrowing (n = 2, 22%) with no ongoing dilations at 3-month follow up post-repair. CONCLUSION EMCA with the Connect-EA device is a safe and feasible minimally-invasive alterative for EA repair in high-risk surgical patients. Promising post-operative outcomes warrant further Phase I investigation. LEVEL OF EVIDENCE IV, Case series of novel operative technique without comparison group.

Abstract
Since the 1970s, magnets have been progressively harnessed for use in minimally invasive treatment of pediatric surgical disease. In particular, multiple magnetic devices have been developed for treating esophageal atresia, pectus excavatum and scoliosis. These devices, which can be placed via small incisions or under endoscopic or fluoroscopic guidance, provide the added benefit of sparing patients multiple large, invasive procedures, and allowing for gradual correction of congenital anomalies over days to months, depending on the disease. In the following text, we detail the current landscape of magnetic devices used by pediatric surgeons, illustrate their use through clinical cases, and review the available body of literature with respect their outcomes and complications.

Abstract
Background: Magnetic compression anastomosis (MCA) is an alternative technique for patients with long-gap esophageal atresia (EA). It allows for preservation of the native esophagus. We aimed to systematically summarize the current literature on MCA in EA. Methods: Studies where neonates with EA were treated with MCA devices were included, while studies on esophageal stenosis were excluded. All clinical studies, including comparative studies, case series, and case reports, were eligible for inclusion. Methodological quality assessment was performed using a validated tool. Results: Twelve studies with a total of 42 patients were included in this review. There was a wide variation among these studies with regard to the time of initiation of MCA (1 day to 7 months), procedure time (13-320 minutes), and magnet characteristics (strength, size, and shape of the magnets used). The time to achieve anastomosis ranged from 1 to 12 days. Stricture at the anastomotic site was reported in almost all the patients, which required multiple endoscopic dilatations (median no. of dilatations/patient = 9.8). Stent placement for refractory stricture was required in 9 (21%) patients, and surgery for stricture was required in 6 (14%) patients. Long-term outcomes included esophageal dysmotility (n = 3) and recurrent pulmonary infections (n = 3) were reported in only four studies. Conclusion: As per the findings of this review, neonates with long-gap EA undergoing MCA would invariably require multiple sittings of endoscopic dilatations (median no. of dilatations/patient = 9.8). Also, there is a wide variation among the included studies in terms of the procedure of MCA. Future studies with a standardized procedure for achieving MCA are needed to determine additional outcomes in this fragile patient population.

Abstract
Infants born with esophageal atresia and tracheoesophageal fistula, a complex congenital malformation occurring in 1/2500-4000 live births, may suffer threats to their cardiac, respiratory, and digestive health in addition to anomalies that may exist in the genitourinary and musculoskeletal systems. Optimal care for these patients throughout their lives is best achieved through a coordinated, multidisciplinary approach that our health care system is not always well-equipped to provide. This review, though not exhaustive, highlights the components of care that pertain to initial surgical reconstruction and subsequent diagnosis and management of the complications that are most frequently encountered. Authors from among the many specialties involved in the care of these patients summarize the current best practice with attention to the most recent advances. Assessment and improvement of quality of life and transition to adult specialists as children grow to adulthood is also reviewed.

Abstract
INTRODUCTION Metallic foreign bodies (mFB) are common following penetrating injuries in children. The mFB commonly occur in the head and neck region and extremity soft tissues. Removal may be indicated due to morbidity related to pain or migration. Extraction can be challenging to localize, often requiring wide exposure, and may be difficult to achieve in cosmetically sensitive areas. Different technological adjuncts have been used to facilitate foreign body removal including fluoroscopy, ultrasound, and more recently in adults, surgical magnets. The most powerful commercially available magnets are rare earth magnets comprised of neodymium iron and boron (Ndy). With the goal of reducing radiation exposure and the morbidity of mFB removal with associated soft tissue injury in children, a strategy was introduced utilizing Ndy to optimize extraction with minimal soft tissue surgical dissection. MATERIALS AND METHODS Two children with extremity mFB treated with Ndy between January 2021 and July 2021 were analyzed. We utilized commercially available ring type neodymium-iron-boron magnets with dimensions of 1 3/8-inch outer diameter x 1/8-inch inner diameter and 1/16 inch thick with a power of 13 200 gauss that were processed for use according to our hospital protocols. Our main clinical indication was for the detection and retrieval of small ferromagnetic foreign bodies embedded in superficial extremity soft tissues. RESULTS In the operating room under general anesthesia, the mFB were localized utilizing fluoroscopy. A 1.0 cm skin incision was made into the subdermal soft tissues overlying the area of the mFB. No surgical tissue dissection was performed. The mFB could not be visualized in the soft tissue. Using fluoroscopy to localize the mFB, the Ndy was then placed into the wound in close proximity to the mFB. The mFB were immediately magnetized to the Ndy and the mFB were extracted from the soft tissues without any further surgical dissection. Two simple interrupted nylon sutures were placed to close the incision. The total operative time was 2 and 2.5 minutes respectively. The children recovered uneventfully and are without complication. CONCLUSIONS The use of Ndy to remove extremity soft tissue mFB in children appears to be feasible, safe, and efficient. Use of the Ndy allowed extraction via a small incision, optimizing the aesthetic result and avoiding the need for cross-sectional imaging, extensive surgical dissection, tissue reconstruction and prolonged operative time or x-ray exposure. The development of magnets of increasing energy density may be indicated to further optimize metallic soft tissue foreign body extraction in children in a minimally invasive manner.

World J Gastrointest Surg 2023; 15:1294-1303. [PMID: 37555127 PMCID: PMC10405115 DOI: 10.4240/wjgs.v15.i7.1294] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/21/2023] [Revised: 04/17/2023] [Accepted: 05/08/2023] [Indexed: 07/21/2023] Open
Abstract
BACKGROUND Magnetic compression anastomosis (MCA) is a simple procedure contributing to a reliable anastomosis. However, digestive-tract reconstruction after total gastrectomy using MCA has not yet been reported. AIM To investigate the feasibility of MCA for simultaneous esophagojejunostomy and jejunojejunostomy after total gastrectomy using beagle dogs. METHODS Sixteen beagles were randomly divided into an MCA group (study group, n = 8) and a manual-suture anastomosis group (control group, n = 8). Two different magnetic anastomosis devices were used in the study group for esophagojejunal and jejunojejunal anastomoses. Both devices included a pair of circular daughter and parent magnets each. The time of esophagojejunostomy and jejunojejunostomy, postoperative complications, and survival rate of the two groups were compared. The dogs were sacrificed one month after the operation and their anastomotic specimens were obtained. Healing was observed by the naked eye and a light microscope. RESULTS Digestive-tract reconstruction after total gastrectomy was successfully completed in both groups (survival rate = 100%). In the study group, esophagojejunal and jejunojejunal anastomoses took 6.13 ± 0.58 and 4.06 ± 0.42 min, respectively, significantly lower than those in the control group (15.63 ± 1.53 min, P < 0.001 and 10.31 ± 1.07 min, P < 0.001, respectively). Complications such as bleeding, anastomotic leakage, and anastomotic stenosis were not observed. In the study group, the magnets did not interfere with each other. Discharge time of the jejunojejunal magnetic anastomosis device was 10.75 ± 1.28 d, while that of the esophagojejunal magnetic anastomosis device was 12.25 ± 1.49 d. Residual silk was found in the control group. The study group showed a greater smoothness of the anastomosis than that of the control group. All layers of anastomosis healed well in both groups. CONCLUSION MCA is a safe and feasible procedure for digestive-tract reconstruction after total gastrectomy in this animal model.

Abstract
The novel use of magnetic force to optimize modern surgical techniques originated in the 1970s. Since then, magnets have been utilized as an adjunct or alternative to a wide array of existing surgical procedures, ranging from gastrointestinal to vascular surgery. As the use of magnets in surgery continues to grow, the body of knowledge on magnetic surgical devices from preclinical development to clinical implementation has expanded significantly; however, the current magnetic surgical devices can be organized based on their core function: serving as a guidance system, creating a new connection, recreating a physiologic function, or utilization of an internal–external paired magnet system. The purpose of this article is to discuss the biomedical considerations during magnetic device development and review the current surgical applications of magnetic devices.

Abstract
BACKGROUND Aim of study is to report our preliminary experience with magnetic anastomosis (magnamosis) treating long-gap esophageal atresia (LGEA), the most challenging condition of esophageal atresia continuum. Magnamosis has been reported in 20 patients worldwide as an innovative and marginally invasive option. METHODS Prospective evaluation of all LGEA patients treated with magnamosis was performed (study registration number: 2535/2021). Main outcomes considered were demographic and surgical features, postoperative complications and feeding within 6-month of follow-up. RESULTS Between June 2020 and January 2021, 5 LGEA patients (Type A, Gross classification) were treated. Median preoperative gap was 5 vertebral bodies. Magnetic bullets were placed at an average age of 81 days of life, leading to successful magnamosis in all cases: 4 infants had primary magnetic repair (one after thoracoscopic mobilization of the pouches), 1 patient had a delayed magnamosis after Foker's procedure. Esophageal anastomosis was achieved after an average of 8 days. No anastomotic leak was found. All patients developed anastomotic stenosis at 6-month follow-up, requiring a mean of 6 dilations each. Full oral feeding was achieved in 3 patients, while 2 were still on oral-gastrostomy feeding. One patient experienced small esophageal perforation after dilation (3 months after magnamosis), distal to the anastomotic stricture and subsequently developed oral aversion. CONCLUSIONS Our preliminary results suggest magnamosis a safe and effective minimally invasive option in patients with LGEA. Absence of postoperative esophageal leaks may represent a major advantage of magnamosis over conventional surgery, although possible high rate of esophageal stenosis should be further evaluated. LEVELS OF EVIDENCE IV (Case series with no comparison group).

Abstract
INTRODUCTION Preservation of native esophagus is a tenet of esophageal atresia (EA) repair. However, techniques for delayed primary anastomosis are severely limited for surgically and medically complex patients at high-risk for operative repair. We report our initial experience with the novel application of the Connect-EA, an esophageal magnetic compression anastomosis device, for salvage of primary repair in 2 high-risk complex EA patients. Compassionate use was approved by the FDA and treating institutions. OPERATIVE TECHNIQUE Two approaches using the Connect-EA are described - a totally endoscopic approach and a novel hybrid operative approach. To our knowledge, this is the first successful use of a hybrid operative approach with an esophageal magnetic compression device. OUTCOMES Salvage of delayed primary anastomosis was successful in both patients. The totally endoscopic approach significantly reduced operative time and avoided repeat high-risk operation. The hybrid operative approach salvaged delayed primary anastomosis and avoided cervical esophagostomy. CONCLUSION The Connect-EA is a novel intervention to achieve delayed primary esophageal repair in complex EA patients with high-risk tissue characteristics and multi-system comorbidities that limit operative repair. We propose a clinical algorithm for use of the totally endoscopic approach and hybrid operative approach for use of the Connect-EA in high-risk complex EA patients.

Abstract
BACKGROUND The use of magnets for the treatment of long gap esophageal atresia or "magnamosis" is associated with increased incidence of anastomotic strictures; however, little has been reported on other complications that may provide insight into refining selection criteria for appropriate use. METHODS A single institution, retrospective review identified three cases referred for treatment after attempted magnamosis with significant complications. Their presentation, imaging, management, and outcomes were reviewed. RESULTS All three patients had prior cervical or thoracic surgery to close a tracheoesophageal fistula prior to magnamosis, creating scar tissue that can prevent magnet induced esophageal movement, leading to either magnets not attracting enough or erosion into surrounding structures. Two patients had a reported four centimeter esophageal gap prior to attempted magnamosis, both failing to achieve esophageal anastomosis, suggesting that these gaps were either measured on tension with variability in gap measurement technique, or that the esophageal segments were fixed in position from scar tissue and unable to elongate. One patient had severe tracheobronchomalacia requiring tracheostomy, with improvement in his airway after eventual tracheobronchopexies, highlighting that magnamosis does not address comorbidities often associated with this patient population. CONCLUSIONS We propose the following inclusion criteria and considerations for magnamosis: an esophageal gap truly less than four centimeters off tension with standardized measurement across centers, cautious use with a history of prior thoracic or cervical esophageal surgery, no associated tracheobronchomalacia or great vessel anomaly that would benefit from concurrent repair, and ideally to be used in centers equipped to manage potential complications. LEVEL OF EVIDENCE Level IV treatment study.

Abstract
BACKGROUND Magnetic compression anastomosis (MCA) is a novel suture-free reconstruction of the digestive tract. It has been used in gastrointestinal anastomosis, jejunal anastomosis, cholangioenteric anastomosis and so on. The traditional operative outcomes of congenital esophageal atresia and benign esophageal stricture are poor, and there are too many complications postoperatively. AIM To test MCA technology to reconstruct the esophagus in dogs, prior to studying the feasibility and safety of MCA in humans. METHODS Thirty-six dogs were randomized into either the study or control group (n = 18 per group). The dogs in the study group were subjected to end-to-end esophageal anastomosis with the magnetic compression device, while those in the control group underwent hand-sewn anastomosis with 4-0 absorbable multifilament Vicryl. We used interrupted single-layer inverting sutures. The anastomosis time, gross appearance, weight and pathology of the anastomosis were evaluated at one month, three months and six months postoperatively. RESULTS The anastomosis time of the MCA group was shorter than that of the hand-sewn group (7.5 ± 1.0 min vs 12.5 ± 1.8 min, P < 0.01). In the MCA group, X-ray examination was performed every day to locate the magnetic device in the esophagus before the magnetic device fell off from the esophagus. In the hand-sewn group, dogs did not undergo X-ray examination. One month after the surgeries, the mean weight of the dogs in the hand-sewn group had decreased more than that of the dogs in the MCA group (11.63 ± 0.71 kg vs 12.73 ± 0.80 kg, P < 0.05). At 3 mo and 6 mo after the operation, the dogs' weights were similar between the two groups (13.75 ± 0.84 kg vs 14.03 ± 0.82 kg, 14.93 ± 0.80 kg vs 15.44 ± 0.47 kg). The number of inflammatory cells in MCA group was lower than that in hand-sewn group on 1 mo after operation. CONCLUSION MCA is an effective and safe method for esophageal reconstruction. The anastomosis time of the MCA group was less than that of the hand-sewn group. This study shows that MCA technology may be applied to human esophageal reconstruction, provided these favorable results are confirmed by more publications.

Abstract
The use of magnet compression to endoscopically create an esophageal anastomosis is an intriguing approach to esophageal atresia repair, but published cases with an existing available device have demonstrated mixed success. One major shortcoming has been the formation of subsequent severe, recalcitrant strictures after primary repair. To address the limitations of the existing device, we recently introduced and reported success with specially designed bi-radial magnets that exhibit a novel geometry and unique tissue compression profile. The aim of this study is to compare the outcomes using our novel device (novel group, NG) with those of previous reports which utilized the historical device (historic group, HG) in a PRISMA-compliant systematic review. Seven studies were eligible for further analysis. Additionally, one of our previously unreported cases was included in the analysis. Esophageal pouch approximation prior to primary repair was performed more frequently in the NG than in the HG (100% NG vs. 21% HG; p = 0.003). There was no difference in the overall postoperative appearance of postoperative stricture (95% HG vs. 100% NG; p = 0.64). The number of postoperative dilatations trended lower in the NG (mean 4.25 NG vs. 9.5 HG; p = 0.051). In summary, magnetic compression anastomosis adds a new promising treatment option for patients with complex esophageal atresia. Prior approximation of pouches and a novel magnet design have the potential to lower the rate of stricture formation.

Abstract
BACKGROUND/PURPOSE Previous studies have shown that a patent, watertight esophageal anastomosis can be accomplished safely using specially-shaped magnets in piglets. However, it is unclear whether such a magnetic esophageal compression anastomosis (MECA) remains patent in the long-term. The purpose of this study was to evaluate the long-term outcome of MECA in an experimental pig model over an observation period of 2 months. METHODS Ten piglets underwent creation of an MECA with custom-made 8 mm magnets and a U-shaped esophageal bypass loop to allow peroral nutrition at eight weeks of life. Two weeks later, the bypass loop was closed surgically, requiring the pigs to swallow via the newly created magnetic compression anastomosis. The pigs were fed soft chow for 2 months. They were monitored for weight gain and signs of dysphagia. At the endpoint of two months, esophagoscopy and contrast esophagography was performed. After removal of the esophagus, the tissues were macroscopiocally and histologically assessed. RESULTS Six piglets survived until the endpoint. In two pigs, closure of the bypass loop failed, these demonstrated mean weight gain of 792 gs/day [95% Confidence interval 575 to 1009 gs/day]. Weight gain in four pigs that exclusively fed via the magnetic anastomosis averaged 577 gs/day [95% confidence interval 434 to 719 gs/day (p = 0.18)]. There were no signs of dysphagia. All magnets passed with the stool within 16 days. After 2 months, a well-formed magnetic compression anastomosis was visible and easily negotiated with a 6.5 mm endoscope. Esophogram and macroscopic findings confirmed patentency of the esophageal anastomoses. Histopathology showed a circular anastomosis lined with contiguous epithelium. CONCLUSION MECA creates a long-term functional and patent anastomosis in pigs. This concept may facilitate minimally-invasive esophageal atresia repair by obviating a technically challenging and time-consuming hand-sewn anastomosis.

Abstract
Thoracoscopic esophageal atresia (EA) repair affords many benefits to the patient; however, intracorporeal suturing of the anastomosis is technically challenging. Esophageal magnetic compression anastomosis (EMCA) is a compelling option for endoluminal EA repair, but available EMCA devices have prohibitive rates of recalcitrant stricture. Connect-EA is a new endoluminal EMCA device system that employs 2 magnetic anchors with a unique mating geometry designed to reliably create a robust anastomosis and decrease rates of leak and stricture. We describe our first-in-human experience with this novel endoluminal device for staged EA repair in 3 patients (Gross type A, B, and C) at high risk for conventional surgical repair. First, the esophageal pouches were approximated thoracoscopically. After acute tension subsided, the device anchors were endoscopically placed in the esophageal pouches and mated. Anchors were spontaneously excreted in 2 cases. Endoscopic repositioning and retrieval of the anchors were required in 1 patient because of narrowed esophageal anatomy. There were no perioperative complications. Patients were managed for 14 to 18 months. The strictures that developed in the patients were membranous and responded well to dilation alone, resolving after 4 to 5 outpatient dilations. Gastrostomies were closed between 6 and 11 months and all patients are tolerating full oral nutrition. Early experience with this new endoluminal EMCA device system is highly favorable. The device offers considerable benefit over conventional handsewn esophageal anastomosis and anastomotic outcomes are superior to available EMCA devices.

Advances and Trends in Pediatric Minimally Invasive Surgery. J Clin Med 2020; 9:jcm9123999.

Abstract
As many meta-analyses comparing pediatric minimally invasive to open surgery can be found in the literature, the aim of this review is to summarize the current state of minimally invasive pediatric surgery and specifically focus on the trends and developments which we expect in the upcoming years. Print and electronic databases were systematically searched for specific keywords, and cross-link searches with references found in the literature were added. Full-text articles were obtained, and eligibility criteria were applied independently. Pediatric minimally invasive surgery is a wide field, ranging from minimally invasive fetal surgery over microlaparoscopy in newborns to robotic surgery in adolescents. New techniques and devices, like natural orifice transluminal endoscopic surgery (NOTES), single-incision and endoscopic surgery, as well as the artificial uterus as a backup for surgery in preterm fetuses, all contribute to the development of less invasive procedures for children. In spite of all promising technical developments which will definitely change the way pediatric surgeons will perform minimally invasive procedures in the upcoming years, one must bear in mind that only hard data of prospective randomized controlled and double-blind trials can validate whether these techniques and devices really improve the surgical outcome of our patients.

Magnetic compression anastomosis with atypical anastomosis for anastomotic stenosis of the sigmoid colon: a case report. Surg Case Rep 2020; 6:59. [PMID: 32291530 PMCID: PMC7156530 DOI: 10.1186/s40792-020-00826-9] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2020] [Accepted: 03/20/2020] [Indexed: 11/30/2022] Open
Abstract
Background Magnetic compression anastomosis (MCA) is mainly applied in the gastrointestinal and biliary tracts through a nonsurgical procedure that can create an anastomosis similar to that obtained through surgery. Magnets usually adsorb in the end-to-end direction (end-to-end anastomosis), exert a strong magnetic force and create an anastomosis according to the size of the magnets. Regular endoscopic dilation is required to prevent restenosis when the anastomotic size is small. We report a case in which MCA was successfully used to treat anastomotic stenosis of the sigmoid colon; the magnets adsorbed in the side-to-side direction rather than the end-to-end direction and generated a wide anastomosis in a short time that did not require endoscopic dilation. Case presentation An 81-year-old woman was admitted to our hospital to treat anastomotic stenosis of the sigmoid colon for closure of transverse colostomy. Two years prior, the Hartmann operation and drainage were performed at other hospitals due to perforated diverticulitis of the sigmoid colon. Obstruction of the sigmoid colostomy occurred, and a transverse colostomy was performed. One year after the first surgery, high anterior resection was performed, but anastomotic stenosis occurred, causing obstruction. MCA was planned because the patient had a history of multiple operations and was expected to have strong adhesions postoperatively. MCA was safely performed, but two magnets were accidently adsorbed in the side-to-side direction. The magnet position could not be changed. The two magnets were expected to move and adsorb in an end-to-end direction naturally due to bowel movements. The magnets that adsorbed in the side-to-side direction dropped from the anus 5 days after treatment, and the anastomosis was observed by colonoscopy. Three ileus tubes were placed from the transverse colostomy beyond the anastomosis to prevent restenosis. Colonoscopy showed that the anastomosis diameter was wider than expected at 14 days after treatment, and endoscopic dilation was not necessary. No complications were observed in this patient’s postoperative course. Finally, closure of the patient’s colostomy was successfully performed. Conclusions MCA with side-to-side anastomosis generated a wide anastomosis in a short time.
