Jejunogastric intussusception after pancreaticoduodenectomy in a patient with HIV

The incidence of jejunogastric intussusception (JGI) after gastric surgery is 0.1%. We report a case of JGI after pancreaticoduodenectomy in a patient with HIV. After presenting to the hospital with abdominal pain and emesis, a CT abdomen/pelvis showed evidence of gastrojejunal anastomosis intussusception into the stomach. Oesophagogastroduodenoscopy was performed, but endoscopic reduction was unsuccessful. Exploratory laparotomy was subsequently performed with a successful reduction of the intussusception and resection of a portion of the small bowel. With only five previously reported cases of JGI after pancreaticoduodenectomy, our case is novel in that it describes JGI in a patient with HIV on highly active antiretroviral therapy, which has been associated with an increased risk of intussusception. While rare, we highlight the importance of having high clinical suspicion for intussusception in patients with risk factors who present with abdominal pain after pancreaticoduodenectomy. Timely diagnosis is critical to optimise patient outcomes.
