Intestinal intussusception as a postoperative complication of gastric bypass.

The gold standard for bariatric surgery is the laparoscopic gastric bypass, which consists in forming a small gastric pouch and a Roux-en-Y anastomosis. We present the case of a 41-year-old female who underwent a laparoscopic gastric bypass 8 years prior to her admission to the emergency room, where she arrived complaining of severe and colicky epigastric abdominal pain. The abdominal computed tomography showed a jejuno-jejunal intussusception, for which the patient underwent urgent exploratory laparotomy with intussusception reduction. Intestinal intussusception is a possible postoperative complication of a Roux-en-Y gastric bypass.

El Método de referencia en la cirugía bariátrica es el bypass gástrico laparoscópico, que consiste en la creación de una bolsa gástrica pequeña, anastomosada al tracto digestivo mediante una Y de Roux. Presentamos el caso de una mujer de 41 años con el antecedente de un bypass gástrico laparoscópico realizado 8 años antes, quien ingresó al servicio de urgencias refiriendo dolor abdominal grave. La tomografía computarizada abdominal evidenció una intususcepción a nivel de la anastomosis yeyuno-yeyuno, por lo que se realizó una laparotomía exploradora con reducción de la intususcepción. Se debe considerar la intususcepción intestinal como complicación posoperatoria de bypass gástrico.

Multiple giant jejunal diverticulosis: A rare clinical presentation of a rarely encountered disease.

Jejunoileal diverticula have a four-fold greater risk of developing general complications and an 18-fold greater risk of perforation compared to duodenal diverticula. While resection is not preferred in asymptomatic cases, surgical intervention may be required in life-threatening conditions. In this case report, a 69-year-old male patient with multiple giant jejunal diverticulum presenting with long-standing and transient symptoms was presented. The patient had a history of appendectomy 15 years before application. During the patient's last admission to the emergency department, contrast-enhanced abdominal computed tomography was ordered and revealed jejunum segments with multiple giant diverticula which were treated by excision by open laparotomy. It was observed that the patient's complaints did not recur and he started to gain weight. In patients admitted to the emergency department with complaints of long-standing abdominal pain, weight loss, and bloating, in whom diagnosis cannot be made, it is recommended to consider diverticulum originating from the jejunum in the differential diagnosis, especially in the presence of abdominal surgery history.

Unusual radiological findings of pediatric jejunojejunal intussusception: A case report.

Intussusception is a common cause of intestinal obstruction in children, especially in those of age <5 years. The typical signs and symptoms of this condition is colicky abdominal pain, bloody mucous stool, and palpated abdominal mass, with a classic target sign finding on abdominal ultrasound. In older children, the symptoms may vary, which necessitates investigation of the cause of intussusception, as it is often caused by a pathologic lead point. We report here the case of a 14-year-old girl with total bowel obstruction, hematochezia, a very dilated reverse C-shaped bowel loop, and intestinal pneumatosis on abdominal X-ray. During laparotomy, we detected jejunojejunal intussusception caused by jejunal polyp. After bowel resection and anastomosis, the patient recovered well and had no other events during follow-up.

Appendiceal carcinoid in a pediatric patient with Peutz-Jeghers syndrome: A case report and comprehensive literature review.

RATIONALE: Peutz-Jeghers syndrome (PJS), a rare autosomal dominant disorder, is characterized by mucocutaneous pigmentations, hamartomatous polyps in the gastrointestinal tract, and a high risk of developing various malignancies. To the best of our knowledge, only 1 case of appendiceal carcinoid associated with PJS has been previously reported in the pediatric population. PATIENT CONCERNS: We report a 7-year-old girl who was admitted for severe, intermittent abdominal pain and cramps, nausea, and vomiting. Multiple brown melanotic macules on the lips, buccal mucosa, and the tongue were noted. DIAGNOSIS: A plain abdominal X-ray in a standing position revealed dilated intestinal loops with multiple air-fluid levels. A computed tomography scan of the abdomen showing a "coffee bean" appearance of the jejunal loop with a transition point to the duodenal loop. Axial-contrast-enhanced computed tomography scan of the abdomen showing dilated jejunum loops, filled with fluid with the swirled appearance of mesentery typical for volvulus. The diagnosis of PJS was based on clinical findings along with the histopathologic confirmation of the hamartomatous polyps. INTERVENTIONS: An emergency laparotomy was performed, revealing a jejunojejunal intussusception starting 40 cm from the duodenojejunal flexure. Jejunotomy revealed that a lead-point intussusception was a necrotic hamartomatous polyp. After resecting the involved jejunal necrotic segment, including the polyp, end-to-end jejuno-jejunal anastomosis was performed. Further exploration revealed the presence of a jejunal mass 80 cm from the duodenojejunal flexure identified as another hamartomatous pedunculated polyp. The polyp was resected, and the enterotomy was then closed transversely. The grossly normal appendix was also removed. OUTCOMES: Clinical findings along with the histopathologically confirmed hamartomatous polyps were consistent with PJS. An appendiceal carcinoid (well-differentiated neuroendocrine tumor, European Neuroendocrine Tumor Society stage pT2) was incidentally detected during histological examination of the appendix. The patient and parents were counseled accordingly, focusing on active surveillance and control of symptoms. Two additional hamartomatous polyps (gastric and jejunal) were detected endoscopically and resected in the fourth postoperative week. A regular, 1-year follow-up and surveillance revealed no complications or recurrences. LESSONS: Unusual neoplasms can occasionally be encountered in well-defined syndromes such as PJS. Therefore, active follow-up and surveillance are mandatory for all patients with PJS.

Enterolith ileus and jejunal diverticulitis from jejunal diverticulosis: the complications of a rare gastrointestinal entity.

Small bowel diverticulosis is rare. False diverticula form in the jejunum, and less commonly, the ileum. As with their large bowel counterparts, these diverticula provide a pocket for stasis of bowel content, leading to the formation of enteroliths. This case report highlights two complications from jejunal diverticulosis: jejunal diverticulitis and a small bowel obstruction as a result of enterolithiasis; the latter being a rare entity which should be a differential diagnosis for any individual presenting with gastrointestinal obstructive symptoms and radiological evidence of small bowel diverticulosis.

Episodic, severe abdominal pain due to isolated jejunal Crohn's disease.

Small bowel Crohn's disease can present with episodic, relapsing, and remitting symptoms and delays in the diagnosis are common. We present a case of a young woman with three years of intermittent abdominal pain and nausea with negative previous evaluations. On presentation, inflammatory markers were elevated, and repeat imaging showed jejunal inflammation, with histopathological examination showing non-caseating granulomas of the small bowel consistent with Crohn's disease. This case highlights the importance of gastroenterologist recognizing the alarm signs in a patient with unexplained symptoms and adds to the literature on the clinical presentation of a rare diagnosis of isolated jejunal Crohn's disease.

Small Intestinal Intussusception Due to Complicated Giant Jejunal Diverticulosis.

Background: Jejunal diverticulosis and jejunal lipomatosis are uncommon conditions. Usually asymptomatic, they may cause severe complications in some cases. Intussusception is unusual in adults, but when diagnosed swiftly it can be treated surgically, usually with good outcome. Case presentation: We present a 60-year-old female patient with a history of chronic malnutrition and anemia, complaining of acute abdominal pain, vomiting and diarrhea. Contrast-enhanced abdominal computed tomography (CT) showed intussusception, multiple giant jejunal diverticula and multiple lipomas. The patient underwent urgent surgery, but radical treatment was not possible due to the extent of the diseases. One month later, another surgery was needed due to ileostomy obstruction caused by lipomas. The patient's condition deteriorated due to malnutrition and concomitant metabolic disorders, which eventually led to her demise. Conclusions: Radical treatment is not always possible in an extensive jejunal disease. Prolonged malnutrition impairs postoperative healing, and therefore surgical or nutritional treatment should be considered in jejunal diverticulosis before the onset of severe complications requiring urgent surgical intervention.
