Jejunogastric intussusception after totally laparoscopic distal gastrectomy for gastric cancer: a rare case report and review of the literature.

Jejunogastric intussusception (JGI) is a rare complication of gastric surgery, with most cases occurring in the form of long-term complications following gastric surgeries. We present a case of JGI in a 74-year-old man who presented with progressive abdominal pain and distention, and was admitted to our hospital. The patient had undergone a totally laparoscopic distal gastrectomy with a Billroth II gastrojejunostomy 9 days previously. Computed tomography and endoscopic findings revealed the presence of a small bowel loop within the gastric lumen, which we failed to reduce in size. We performed an emergency laparoscopic exploration and immediate reduction of the JGI. The efferent and afferent loops were then fixed to the mesentery and the stomach. The postoperative course was uneventful and the patient remained asymptomatic during the 1-year follow-up period.
