Abstract
Gastrointestinal (GI) sequelae, such as vomiting, hyperacidity, dysphagia, dysmotility, and diarrhea, are nearly universal among patients with nephropathic cystinosis. These complications result from disease processes (e.g., kidney disease, cystine crystal accumulation in the GI tract) and side effects of treatments (e.g., cysteamine, immunosuppressive therapy). GI involvement can negatively impact patient well-being and jeopardize disease outcomes by compromising drug absorption and patient adherence to the strict treatment regimen required to manage cystinosis. Given improved life expectancy due to advances in kidney transplantation and the transformative impact of cystine-depleting therapy, nephrologists are increasingly focused on addressing extra-renal complications and quality of life in patients with cystinosis. However, there is a lack of clinical data and guidance to inform GI-related monitoring, interventions, and referrals by nephrologists. Various publications have examined the prevalence and pathophysiology of selected GI complications in cystinosis, but none have summarized the full picture or provided guidance based on the literature and expert experience. We aim to comprehensively review GI sequelae associated with cystinosis and its treatments and to discuss approaches for monitoring and managing these complications, including the involvement of gastroenterology and other disciplines.

Abstract
Immunocompromised patients are a heterogeneous and diffuse category frequently presenting to the emergency department with acute surgical diseases. Diagnosis and treatment in immunocompromised patients are often complex and must be multidisciplinary. Misdiagnosis of an acute surgical disease may be followed by increased morbidity and mortality. Delayed diagnosis and treatment of surgical disease occur; these patients may seek medical assistance late because their symptoms are often ambiguous. Also, they develop unique surgical problems that do not affect the general population. Management of this population must be multidisciplinary.This paper presents the World Society of Emergency Surgery (WSES), Surgical Infection Society Europe (SIS-E), World Surgical Infection Society (WSIS), American Association for the Surgery of Trauma (AAST), and Global Alliance for Infection in Surgery (GAIS) joined guidelines about the management of acute abdomen in immunocompromised patients.

Abstract
A 58-year-old man who underwent cadaveric kidney transplantation twice presented to hospital with a perforated epiphrenic diverticulum. Computed tomography revealed epiphrenic diverticulitis and right pleural effusion. Upper gastrointestinal fibroscopy showed an epiphrenic diverticulum full of food residue. He was transferred to our hospital, where we performed percutaneous endoscopic gastrostomy under general anesthesia in the supine position before thoracoscopy. Thoracoscopic esophagectomy was performed in the semi-prone position under 6-10 mmHg artificial pneumothorax via the right thoracic cavity. We performed subtotal esophagectomy to remove sources of infection because the esophageal wall surrounding the diverticulum was too thick to close or to perform diverticulectomy. A cervical esophagostomy was constructed after the thoracic procedure. The patient was managed with continuous hemodiafiltration and administered immunosuppressants and steroids to preserve the transplanted kidney. Continuous hemodiafiltration was stopped on postoperative day (POD) 4. The patient was discharged from the intensive care unit on POD 10 and transferred to the original hospital on POD 24 for rehabilitation. The second operative stage was performed on POD 157 at our hospital. We performed gastric tube reconstruction via the ante-sternal route and anastomosed the tube to the cervical esophagus. The postoperative course was uneventful; the patient was transferred to the original hospital on POD 15 after the second operation. Minimally invasive surgery was sufficient to treat perforated epiphrenic diverticulum while preserving the transplanted kidney. We recommend completely removing the source of infection and reducing surgical invasiveness to preserve the transplanted kidney in cases of esophageal perforation following kidney transplantation.

Abstract
Colovesical fistula per se is a rare condition and most commonly occurs secondary to diverticular disease in normal patients. Colovesical fistula in the setting of post-renal transplantation is even rarer and very few cases have been reported in literature. Patients with autosomal-dominant polycystic kidney disease (ADPKD) are predisposed to diverticulosis and hence are at a higher risk for fistula formation. Herein, we report a case of colovesical fistula in a renal allograft recipient with ADPKD in the absence of diverticulosis. The patient was successfully operated and is stable with no complications at 1-year follow-up.

Abstract
BACKGROUND Diagnosis and treatment of diverticulitis in immunosuppressed patients are more challenging than in immunocompetent patients, as maintenance immunosuppressive therapies may mask symptoms or impair the patient's ability to counteract the local and systemic infective sequelae of diverticulitis. The purpose of this study was to compare the in-hospital mortality and morbidity due to diverticulitis in immunosuppressed and immunocompetent patients and identify risk factors for lethal outcomes. METHODS This retrospective study included consecutive in-patients who received treatment for colonic diverticulitis at our institution between April 2008 and April 2014. Patients were divided into immunocompetent and immunosuppressed groups. Primary end points were mortality and morbidity during treatment. Risk factors for death were evaluated. RESULTS Of the 227 patients included, 15 (6.6%) were on immunosuppressive therapy for solid organ transplantation, autoimmune disease, or cerebral metastasis. Thirteen of them experienced colonic perforation and showed higher morbidity (p = 0.039). Immunosuppressed patients showed longer stays in hospital (27.6 v. 14.5 d, p = 0.016) and in the intensive care unit (9.8 v. 1.1 d, p < 0.001), a higher rate of emergency operations (66% v. 29.2%, p = 0.004), and higher in-hospital mortality (20% v. 4.7%, p = 0.045). Age, perforated diverticulitis with diffuse peritonitis, emergency operation, C-reactive protein > 20 mg/dL, and immunosuppressive therapy were significant predictors of death. Age (hazard ratio [HR] 2.57, p = 0.008) and emergency operation (HR 3.03, p = 0.003) remained significant after multivariate analysis. CONCLUSION Morbidity and mortality due to sigmoid diverticulitis is significantly higher in immunosuppressed patients. Early diagnosis and treatment considering elective sigmoid resection for patients with former episodes of diverticulitis who are wait-listed for transplant is crucial to prevent death.

Abstract
Stercoral perforation is a rare cause of bowel perforation. It is caused by faecal impaction, which generates pressure against the colon wall, leading to ischaemic necrosis and subsequent perforation. Since diagnosis is often delayed, stercoral perforation is usually mistreated as constipation or faecal impaction, leading to high mortality. This report presents a case of stercoral perforation in a woman aged 34 years who was promptly diagnosed and successfully treated.

World J Emerg Surg 2016; 11:43. [PMID: 27582783 PMCID: PMC5006611 DOI: 10.1186/s13017-016-0101-6] [Citation(s) in RCA: 33] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2016] [Accepted: 08/17/2016] [Indexed: 02/07/2023] Open
Abstract
AIMS Due to the increasing number of solid organs transplantations, emergency abdominal surgery in transplanted patients is becoming a relevant challenge for the general surgeon. The aim of this systematic review of the literature is to analyze morbidity and mortality of emergency abdominal surgery performed in transplanted patients for graft-unrelated surgical problems. METHODS The literature search was performed on online databases with the time limit 1990-2015. Studies describing all types of emergency abdominal surgery in solid organ transplanted patients were retrieved for evaluation. RESULTS Thirty-nine case series published between 1996 and 2015 met the inclusion criteria and were selected for the systematic review. Overall, they included 71671 transplanted patients, of which 1761 (2.5 %) underwent emergency abdominal surgery. The transplanted organs were the heart in 65.8 % of patients, the lung in 22.1 %, the kidney in 9.5 %, and the liver in 2.6 %. The mean patients' age at the time of the emergency abdominal surgery was 49.4 ± 7.4 years, and the median time from transplantation to emergency surgery was 2.4 years (range 0.1-20). Indications for emergency abdominal surgery were: gallbladder diseases (80.3 %), gastrointestinal perforations (9.2 %), complicated diverticulitis (6.2 %), small bowel obstructions (2 %), and appendicitis (2 %). The overall mortality was 5.5 % (range 0-17.5 %). The morbidity rate varied from 13.6 % for gallbladder diseases to 32.7 % for complicated diverticulitis. Most of the time, the immunosuppressive therapy was maintained unmodified postoperatively. CONCLUSIONS Emergency abdominal surgery in transplanted patients is not a rare event. Although associated with relevant mortality and morbidity, a prompt and appropriate surgery can lead to satisfactory results if performed taking into account the patient's immunosuppression therapy and hemodynamic stability.

Abstract
Although gastroduodenal ulcers are common in solid organ transplant patients, there are few reports on multiple giant ulcers in the distal ileum and ileocecal valve caused by immunosuppressants Herein, we report on a liver transplant recipient and a renal transplant recipient with multiple large ulcers in the distal ileum and ileocecal valve who rapidly achieved ulcer healing upon withdrawal of sirolimus or tacrolimus and administration of thalidomide. In case 1, a 56-year-old man with primary hepatocellular carcinoma had received a liver transplantation. Tacrolimus combined with sirolimus and prednisolone was used as the anti-rejection regimen. Colonoscopy was performed because of severe abdominal pain and diarrhea at post-operative month 10. Multiple giant ulcers were found at the ileocecal valve and distal ileum. The ulcers healed rapidly with withdrawal of sirolimus and treatment with thalidomide. There was no recurrence during 2 years of follow-up. In case 2, a 34-year-old man with end-stage kidney disease received kidney transplantation and was put on tacrolimus combined with mycophenolate mofetil and prednisolone as the anti-rejection regimen. Twelve weeks after the operation, the patient presented with hematochezia and severe anemia. Colonoscopy revealed multiple large ulcers in the ileocecal valve and distal ileum, with massive accumulation of fresh blood. The bleeding ceased after treatment with intravenous somatostatin and oral thalidomide. Tacrolimus was withdrawn at the same time. Colonoscopy at week 4 of follow-up revealed remarkable healing of the ulcers, and there was no recurrence of bleeding during 1 year of follow-up. No lymphoma, tuberculosis, or infection of cytomegalovirus, Epstein-Barr virus, or fungus was found in either patient. In post-transplantation cases with ulcers in the distal ileum and ileocecal valve, sirolimus or tacrolimus should be considered a possible risk factor, and withdrawing them or switching to another immunosuppressant might be effective to treat these ulcers.

Abstract
BACKGROUND Immunosuppression could increase the complication rate in patients with acute diverticulitis. This would justify a low threshold for elective sigmoid resection in these patients after an episode of diverticulitis. Well-documented groups of immunocompromised patients are transplant patients, in which many prospective studies have been conducted. OBJECTIVES The aim of this systematic review is to assess the incidence of complicated diverticulitis in post-transplant patients. DATA SOURCE We searched MEDLINE, EMBASE, CINAHL, and Cochrane databases for papers published between January 1966 and January 2014. STUDY SELECTION AND INTERVENTION Publications dealing with post-transplant patients and left-sided diverticulitis were eligible for inclusion. The following exclusion criteria were used for study selection: abstracts, case-series and non-English articles. MAIN OUTCOME MEASURES Primary outcome measure was the incidence of complicated diverticulitis. Secondary outcome was the incidence of acute diverticulitis and the proportion of complicated diverticulitis. Pooling of data was only performed when more than five reported on the outcome of interest with comparable cohorts. Only studies describing proportion of complicated diverticulitis and renal transplant studies were eligible for pooling data. RESULTS Seventeen articles met the inclusion criteria. Nine renal transplant cohorts, four mixed lung-heart-heart lung transplant cohorts, two heart transplant cohorts, and two lung cohorts. A total of 11,966 post-transplant patients were included in the present review. Overall incidence of complicated diverticulitis in all transplantation studies ranged from 0.1 to 3.5%. Nine studies only included renal transplant patients. Pooled incidence of complicated diverticulitis in these patients was 1.0% (95% CI 0.6 to 1.5%). Ten studies provided proportion of complicated diverticulitis. Pooled incidence of acute diverticulitis in these studies was 1.7% (95% CI 1.0 to 2.7%). Pooled proportion of complicated diverticulitis among these patients was 40.1% (95% CI 32.2 to 49.7%). All studies were of moderate quality using the MINORS scoring scale. CONCLUSION The incidence of complicated diverticulitis is about one in 100 transplant patients. Additionally when a transplant patient develops an episode of acute diverticulitis, a high proportion of patients have a complicated disease course.

Abstract
AIM To compare the perioperative outcomes following surgery for sigmoid diverticulitis in transplant recipients and immunocompetent patients. METHOD Solid organ transplant recipients operated on for sigmoid diverticulitis from 1995 to 2010 were case-matched to immunocompetent patients based on surgical procedure, American Society of Anesthesiologists classification, Hinchey score, elective vs urgent surgery, age ± 10 years and year of surgery ± 5 years. Demographics, clinical presentation and perioperative outcomes were assessed. RESULTS Of 5329 consecutive patients undergoing heart, lung, kidney and liver transplantation since 1995, 51 (0.6%) underwent surgery for diverticulitis between 1995 and 2010 with 14% mortality and 45% morbidity. Urgent surgery in 37/51 patients [Hartmann's procedure 28, sigmoidectomy with diverting ileostomy 8, loop ileostomy 1 (9 cases within 2 months after transplantation)] was associated with significantly increased postoperative mortality (19%vs 0%, P = 0.01), increased morbidity (51%vs 24%, P = 0.03) and longer mean hospital stay (19 vs 13 days, P = 0.1) when compared with immunocompetent patients. Four patients undergoing urgent surgery had suffered previous episodes of diverticulitis treated nonoperatively. Elective surgery was associated with no mortality in 14 transplant recipients (nine sigmoidectomy with diverting ileostomy, five sigmoidectomy without diversion) or in immunocompetent controls. Following elective procedures, transplant recipients had similar morbidity and increased hospital stay (29% and 9.6 vs 6.5 days, P = 0.2, respectively). Permanent stoma rates and postoperative morbidity after stoma takedown were comparable in the two groups. All living patients except one (kidney) retained their graft function. CONCLUSIONS Urgent surgery for sigmoid diverticulitis in transplant recipients is associated with worse postoperative outcomes when compared with immunocompetent patients, unlike elective surgery. Future studies will need to clarify the role of early surgery after the first diverticulitis episode.

Abstract
PURPOSE Abdominal complications after lung transplantation (LuTx) are associated with a high mortality risk. Aim of the present study was to analyse frequency and outcome of abdominal interventions following LuTx. METHODS Retrospective analysis of the requirement of abdominal surgery including data of 754 patients undergoing LuTx at the Hannover Medical School, Germany, between January 2000 and December 2008. RESULTS In the course of lung transplantation, 55 patients (7%) were in need of surgical interventions due to abdominal complications. Following LuTx, 35 individuals were operated in 43 cases of emergency indication. The leading diagnosis was bowel perforation (n = 10) with surgery performed 10.4 months after LuTx, although 7 of 10 patients were operated within the first 4 weeks post-transplantation. Emergency interventions were associated with a mortality rate of 28%, 42% thereof after bowel perforation. Elective surgical treatments (n = 31) were diverse and had no influence on mortality. CONCLUSIONS Early abdominal complications after LuTx correlate with a high mortality rate. Perforation of the bowel was the leading diagnosis with a severe impact on the outcome. Thus, in cases of an acute abdomen after LuTx, we recommend the broad use of further diagnostic measures as well as an early decision for explorative laparotomy.

Abstract
BACKGROUND The clinical course of diverticular disease in immunosuppressed patients is widely believed to be more severe than in the general population. In this study we systematically reviewed the literature regarding the epidemiology and clinical course of diverticulitis in immunosuppressed patients. Our goal was to develop recommendations regarding the care of this group of patients. METHODS Using PubMed and Web of Knowledge we systematically reviewed all studies published between 1970 and 2009 that analyzed the epidemiology, clinical manifestation, or outcomes of treatment of diverticulitis in immunosuppressed patients. Keywords of "transplantation," "corticosteroid," "HIV," "AIDS," and "chemotherapy" were used. RESULTS Twenty-five studies met our inclusion criteria. All of these studies focused on the impact of diverticulitis in patients with transplants or on chronic corticosteroid therapy. The reported incidence of acute diverticulitis in these patients was approximately 1% (variable follow-up periods). Among patients with known diverticular disease the incidence was 8%. Mortality from acute diverticulitis in these patients was 23% when treated surgically and 56% when treated medically. Overall mortality was 25%. CONCLUSIONS Our study summarizes evidence that patients with transplants or patients on chronic corticosteroid therapy 1) have a rate of acute diverticulitis that is higher than the baseline population and 2) a mortality rate with acute diverticulitis that is high. Further research is needed to define whether these risks constitute a mandate for screening and prophylactic sigmoid colectomy.

Abstract
Emergent operation after renal transplantation (RT) has traditionally been associated with substantial morbidity and mortality. We reviewed 2340 adult patients who underwent RT at our tertiary care center and identified 55 patients who required acute care surgical consultation within 1 year of transplantation. Of these, 43 were treated operatively and 12 nonoperatively Primary diagnoses were intestinal problems in 29 patients (53%), including diverticulitis, ischemia, perforation, obstruction, and bleeding; cholecystitis in 10 (18%); fluid collections in six (11%), appendicitis and hernias in two each (4%); gastritis in one (2%); and no diagnosis in five (9%). Colonic pathology was treated with resection and diversion in 14 of 16 patients who underwent surgery. Acute allograft rejection preceded the surgical problem in five patients. Complications occurred in 13 per cent of patients, and mortality was 9 per cent. Colonic ischemia had a fulminating presentation and particular morbidity. We conclude that acute gastrointestinal emergencies after RT are rare and that early and aggressive intervention using an acute care surgical model yields excellent results.
