Intussusception is a rare condition in adults and presents a diagnostic challenge. Clinical presentation tends to be chronic and non-specific. Unlike the pediatric population, most adult intussusceptions have structural lesions as lead points. Here, we present a case of jejunojejunal intussusception in a 27-year female due to adenoma of small bowel.

Intussusception is a condition in which there is telescoping ladder f one bowel segment into another resulting in mechanical bowel obstruction.

Intussusception in healthy adults is rare and often associated with oncologic diseases. This case report presents a case of an ileo-colic intussusception reaching down to the descending colon in a healthy adult that required ileo-colic resection.

We present a case of a 78-year-old male patient with acute onset unspecific abdominal pain. The medical history was unremarkable. Preoperative radiologic assessments showed an invagination of the small intestine into the colon without any signs of polyps or tumours. An emergency laparotomy with resection of the affected intestine was performed. The pathologist described a 49 cm length of intussuscepted colon and an additional 7 cm intussusception of the terminal ileum. A circular area with multiple polyps extending over 8 cm in the colon could be identified. The microscopic findings showed a low-grade dysplasia within this area. Following surgery, the patient was discharged to rehabilitation after a ten-day hospitalization.

Intussusception in adults is rare and the clinical presentation includes unspecific symptoms making the diagnosis challenging. In 90% of the cases, a pathologic lesion is found (two-thirds are neoplasms). An intussusception involving the colon should be treated surgically without prior reduction due to the high incidence of a neoplasm and the risk for perforation and tumour dissemination.

In the literature, neoplastic disease represents the major cause for intussusception in adults. This report presents a rare case of an ileo-colic intussusception reaching down to the descending colon treated successfully with a subtotal colectomy.

Intussusception is a differential diagnosis in adults with abdominal pain.

Intestinal intussusception caused by intestinal duplication and ectopic pancreas is extremely rare in the clinic and has not been reported previously.

A 29-year-old man was admitted to the hospital for chronic abdominal pain and bloating. The preoperative diagnosis was intestinal obstruction and intussusception. Then, laparotomy, partial small intestinal resection and extraintestinal decompression were performed. Postoperative pathology confirmed intestinal duplication and ectopic pancreas. After surgery, the patient recovered well with no complications. No recurrence was observed after more than 5 mo of follow-up.

We report a new case of a young male with intussusception caused by intestinal duplication and ectopic pancreas. Surgery is the main treatment for these conditions. This study aimed to raise awareness and provide information to improve the clinical management of this rare yet serious condition.

A colon lipoma is defined as a benign tumor made of adipose tissue present in the submucosa. Lipomas of the colon are unusual with a frequency of 0.035%-4.4%. We present an uncommon case of a 41-year-old female with left colonic lipoma causing intussusception. The patient presented with abdominal pain at the left iliac fossa. She underwent an emergency exploratory laparotomy plus left hemicolectomy and was followed in the surgical out-patient clinic postoperatively. She was found doing well taking a normal diet and having normal bowel habits. The overall prognosis depends on the complete removal of the tumor.

Intussusception is uncommon in adults and often manifests as nonspecific symptoms. Owing to its low incidence and the lack of knowledge on the symptoms, causes, and treatment of adult intussusception (AI), many surgeons may have limited experience in the diagnosis and treatment of intussusception. This study aimed to describe the experience of AI and discuss its clinical presentation, etiology, and management.

I retrospectively reviewed patients aged 19 years and older who were diagnosed with intussusception at a single institution between March 2010 and December 2019.

Among 28 patients who were finally analyzed, abdominal pain was the most commonly observed symptom. Ileocolic and ileoileal intussusceptions were the most common locations, and a lead point was observed in 19 cases (68%), of which malignancy was observed in six (21%). Bowel resection was performed in 27 cases. According to the pathological findings of the tissue from the resected section, nine and three cases of small bowel intussusception (SBI) were benign and malignant, respectively, whereas 13 and three cases of colonic intussusception (CI) were benign and malignant, respectively. On comparing SBI and CI, it was observed that most variables did not significantly differ, except for the duration of symptoms.

SBI had a higher lead point than CI. The rate of malignancy in CI cases in this study was lower than that reported in other studies. En-bloc resection can be considered the first option for the treatment of AI.

Cecal gastrointestinal stromal tumors (GIST) constitute a rarer subtype of all GISTs. Rarely, it can present with ileocolic intussusception in adults making it a challenging diagnosis due to non-specific clinical features.

A 30-year previously healthy woman presented with lower abdominal pain and a distended abdomen who was subsequently diagnosed with ileocolic intussusception on a CT scan. Intraoperatively, a pedunculated polypoid hard mass was identified in the cecum and thus, a standard right hemicolectomy was performed with the suspicion of malignancy. Histopathology of the resected mass confirmed CD117 negative, spindle type GIST.

Cecal GIST presenting in the form of ileocolic intussusception is rare. Contrast-enhanced CT scan is the preferred imaging modality for the evaluation of patients with suspected GIST to determine the extent of the tumor, the presence or absence of metastatic disease alongside evaluation of the possibility of complete resection. Adjuvant imatinib therapy following complete resection decreases the disease recurrence.

Intussusception in an adult can be the first manifestation of underlying malignancy like GIST. Complete surgical resection of the tumor with a negative margin offers long-term survival.

Intussusception is defined as invagination of one segment of the bowel into an immediately adjacent segment. The intussusception refers to the proximal segment that invaginates into the distal segment, or the intussusception (recipient segment). Intussusception, more common occur in the small bowel and rarely involve only the large bowel. In direct contrast to pediatric etiologies, adult intussusception is associated with an identifiable cause in almost all the symptomatic cases while the idiopathic causes are extremely rare. As there are many common causes of acute abdomen, intussusception should be considered when more frequent etiologies have been ruled out. In this review, we discuss the symptoms, location, etiology, characteristics, diagnostic methods and treatment strategies of this rare and enigmatic clinical entity in adult.

Intestinal intussusception is rare in adults and it is associated with lead points.

Intestinal intussusception is rare in adults and it is associated with lead points affecting the colon in around 17% of patients. Lipomas are very rare benign tumors which may act as lead points for intestinal intussusception. Indeed, the incidence of intestinal intussusception is much rare when caused by lipomas.

Our patient is a 29-year-old male, previously healthy and admitted for severe right lower quadrant abdominal pain of 2-day duration. Computed tomography (CT) scan of the abdomen and pelvis showed large mass of fat consistency containing colon structure.

Urgent laparotomy was opted during which colo-colic intussusception was diagnosed and right hemicolectomy with primary ileocolic anastomosis was performed. Pathology report showed that intussusception was induced by a colon lipoma. Patient had an uneventful hospital stay and was discharged on post-operative day 5.

Thus we recommend that colo-colic intussusception caused by lipoma be considered in the differential when diagnosing adults with right lower quadrant pain.

Adult intussusception is less common than paediatric intussusception. The aim of this study was to explore the clinical presentation, aetiology, diagnosis and treatment of adult intussusception.

Adults (>18 years) with intussusception treated by surgical or conservative measures were included from January 2005 to January 2018, and the manifestation, types, diagnosis and treatment of adult intussusception in our centre were reviewed.

A total of 150 patients with adult intussusception were included in this study. The clinical manifestations included 111 cases (74%) of abdominal pain, 38 cases (25.3%) of bloody stool, 37 cases (24.7%) of bowel obstructions, 33 cases (22%) of abdominal distension, 29 cases (19.3%) of nausea and vomiting, 19 cases (12.7%) of an abdominal mass, and 12 cases (8.0%) of diarrhoea. The types of intussusception were classified into 36 cases (24%) of enteric intussusception, 87 cases (58%) of intestine-colon intussusception and 27 cases (18%) of colonic intussusception. Surgical intervention was applied in 139 cases (92.7%), including 115 patients who underwent open surgery, and laparoscopy-assisted surgery was performed in 24 patients. The main pathogenesis of intussusception was malignant tumors in 51 cases (36.7%) and benign tumors and polyps in 49 cases (35.3%).

Malignant and benign tumors are the main causes of adult intussusception. Abdominal CT is the preferred evaluation method for the preoperative diagnosis of this condition. The choice of surgical procedure depends on the location and type of intussusception.
