Rare postoperative hemorrhage after robotic-assisted pancreatoduodenectomy for pancreatic head cancer: a case report

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.

Confusing delayed hematemesis, unusual arterial hemorrhage after pancreaticoduodenectomy: a case report

Pancreaticoduodenectomy (PD) is one of the most complex surgeries and is associated with a high rate of complications, including bleeding, delayed gastric emptying (DGE), and pancreatic fistula. Although the frequency of postoperative hemorrhage is not high, this complication results in severe adverse outcomes. A 67-year-old man was diagnosed with pancreatic cancer and underwent PD. On the tenth day after surgery, he developed hypovolemic shock with hematemesis. Urgent digital subtraction angiography identified the bleeding artery as the jejunal mesenteric artery at the afferent loop, and the bleeding artery was embolized with two coils. After digital subtraction angiography, the patient had an uneventful recovery with no further complications. Therefore, we concluded that it is possible that bleeding may occur in the afferent loop when hemorrhage occurs after PD.

Jejunogastric intussusception after pancreaticoduodenectomy: a case report

Background

Jejunogastric intussusception (JGI) is a rare, but potentially fatal complication that can occur following gastric surgery, and the reported incidence of JGI is as low as 0.1%. Early diagnosis and treatment are critical for JGI to prevent major complications such as bowel necrosis and death. Although emergency surgery is the standard treatment, endoscopic reduction has also been reported to be effective in JGI patients without bowel necrosis. Several early recurrent cases treated with surgical or endoscopic reduction have been reported. We report an extremely rare case of JGI after pancreaticoduodenectomy (PD) using Child’s procedure that was successfully treated with surgical reduction and fixation.

Case presentation

An 81-year-old man who had undergone PD using Child’s procedure 3 years ago presented to our hospital with epigastric pain and nausea. His vital signs were stable, and abdominal examination revealed mild tenderness with a palpable mass in the mid-epigastrium. Abdominal computed tomography (CT) and gastroscopy revealed a JGI of the efferent loop, and exploratory laparotomy was immediately performed. During the operation, the efferent loop showed no adhesions and was intussuscepted through the gastrojejunostomy into the gastric lumen. An incision in the anterior wall of the stomach revealed no evidence of ischemia of the intussusceptum. The efferent loop was reduced using Hutchinson’s maneuver and fixed to the afferent loop to prevent a recurrence. The postoperative course was uneventful, and there was no sign of recurrence 12 months postoperatively.

Conclusions

JGI after PD is an extremely rare, but has severe complications. Surgery might be the optimal treatment for JGI in terms of preventing recurrence, even in cases without bowel necrosis.
