Clinical case of intussusception of the jejunum into gastroenteroanastomosis after gastric ­resection

Intussusception is one of the varieties of mixed (strangulation and obturation) mechanical intestinal obstruction. It arises as a result of the introduction of the adducting segment of the intestine into the abducting one. Gastroduodenal intussusception is an extremely rare type of high intestinal obstruction. It most often occurs after surgery on the stomach and much less often in non-operated patients. Intussusception of the jejunum into the stomach can occur soon after surgery, but most often, this complication occurs 515 years after the intervention. This paper describes a case of retrograde intussusception that arose 9 years after the Billroth II gastric resection with Braun anastomosis. This clinical case acquaints specialists with the possibility to encounter this pathology in clinical practice and demonstrates the appropriateness of differential diagnostics in cases with similar clinical symptoms.

Case report and literature review: patient with gastroduodenal intussusception due to the gastrointestinal stromal tumor of the lesser curvature of the gastric body

Background Intussusception in adult patient is rare. Gastroduodenal intussusception due to the gastrointestinal stromal tumors is infrequently described in the literature. Authors present a case of gastroduodenal intussusception due to the low-risk gastrointestinal stromal tumor of the lesser curvature of the gastric body with literature review. Case presentation Sixty-two-year-old male was admitted to our hospital with symptoms of acute gastric outlet obstruction. Imaging studies confirmed a lesion of the gastric wall producing gastroduodenal intussusception with pylorus obstruction. Upon laparotomy a tumor mass of the lesser curvature of the gastric body that invaginated through the pylorus into the duodenum was found. Desinvagination and resection of the tumor with the adequate resection margins were performed. Histology reveled a low-risk gastrointestinal stromal tumor. Due to favorable outcome only observation was suggested by the multidisciplinary team. Conclusions Gastroduodenal intussusception due to the gastrointestinal stromal tumor of the gastric wall is a rare event. Surgical resection is the treatment of choice. In selected cases laparosopic resection of the tumor can be performed.
