Jejunojejunal intussusception induced by a gastrointestinal stromal tumor: a case report and literature review

Intussusception is defined as the invagination of a proximal segment of the bowel into the adjoining or distal segment. In most adults with intussusception, there is a demonstrable lead point with a definite pathologic abnormality. The clinical features of intussusception include chronic intermittent abdominal pain, nausea and vomiting, constipation, and a palpable abdominal mass. The present case report describes a 62-year-old woman with a 2-week history of abdominal pain and 9-day history of vomiting. Clinical, imaging, and histologic evaluations revealed a jejunojejunal intussusception with a gastrointestinal stromal tumor as the lead point. A gastrointestinal stromal tumor should be considered as a possible lead point in adult patients with intussusception. The implication of reducing the intussusception prior to tumor resection requires further evaluation in view of the risk of venous embolism, including direct spread of malignant cells, in cases involving a large polypoid mass with a necrotic surface that extends to the serosa as shown by intraoperative examination. Accordingly, the rationale for adjuvant therapy with imatinib also requires further evaluation.

Jejunojejunal intussusception: an unusual case of postoperative intestinal obstruction

Intussusception is a rare cause for postoperative intestinal obstruction. We report a case of intussusception in the early postoperative period following resection of proximal jejunum and end to end anastomosis. Computed tomography showed jejunal intussusception, which was confirmed on exploration. The anastomotic site was acting as the lead point, which was resected after reduction and reanastomosed in a single layer. The patient had uneventful recovery. Very few similar cases are reported in the literature and all the reported cases are following free jejunal transfer for pharyngo-oesophageal reconstruction.

Antegrade jejunojejunal intussusception inside a retrograde jejunogastric intussusception (double intussusception)-A rare case report

•

Acute retrograde jejunogastric intussusception is a rare event.

•

It presents as sudden onset epigastric pain with mass and vomiting in a patient who underwent previous gastric surgery.

•

The treatment of acute jejunogastric intussusception is prompt surgery.

•

Early surgical intervention prevents vascular compromise and bowel gangrene.

Introduction

Jejunogastric intussusception through a gastrojejunal stoma along with a jejunojejunal intussusception (intussusception within an intussusception) is a rare but serious complication of previous gastric surgery such as gastrojejunostomy and Billroth II gastrectomy. The incidence of which is less than 0.1%.

Case presentation

An elderly male presented with an abdominal lump, diffuse abdominal pain and vomiting for one-day duration. Ultrasound and CECT abdomen revealed dilated stomach with jejunojejunal intussusception herniating into stomach. Emergency laparotomy was done with manual reduction of intussusception loops and roux- en-y anastomosis.

Discussion

The number of cases reported in literature involving a jejunogastric intussusception following gastric surgery was about 300.Furthermore, there have been only two reported cases of jejunogastric intussusception along with jejunojejunal intussusception. The rarity of this clinical event makes it imperative for a high index of suspicion in patients presenting with abdominal pain following gastric surgery.

Conclusion

The mortality of this condition ranges from 10% to 50%. Hence prompt diagnosis and early surgical intervention prevents vascular compromise and bowel gangrene.

Burkitt lymphoma as a lead point for jejunojejunal intussusception in a human immunodeficiency virus patient

Intussusception is commonly seen in children but is rare in adults and represents only 5% of all intussusceptions causing 1% of intestinal obstructions. More than 50% of these intussusceptions in adults are due to intestinal neoplasms, including malignant lymphoma, e.g., Burkitt lymphoma. These lymphomas are more common in human immunodeficiency virus (HIV)-positive patients than in the general population. We present a case of a young male who was diagnosed with HIV when he developed intestinal obstruction and intussusception secondary to Burkitt lymphoma. He was managed with surgical resection followed by chemotherapy and antiretroviral treatment. HIV patients presenting with acute abdomen pose a diagnostic challenge to clinicians due to a wide range of differential diagnoses including inflammatory, infectious and neoplastic conditions. In a young HIV patient presenting with acute abdomen, intussusception caused by Burkitt lymphoma should be considered in the differential.
