Anastomotic stenosis after pancreaticoduodenectomy: an endoscopic solution

摘要

Obstruction of the gastrojejunostomy (GJJ) after pancreaticoduodenectomy is often caused by malignant tumor ingrowth. Patients present with nausea and vomiting suggestive of gastric outlet obstruction (GOO). GOO may require surgical treatment, which is associated with relief of symptoms in 72% of patients but with the risk of morbidity.Long-term anastomotic durability is difficult to assess in patients with malignant diseases because of the compromised survival time. Anastomotic complications after pancreaticoduodenectomy reported in patients with benign diseases are strictures of biliary and pancreatic anastomoses. Stent placements in these cases have low mortality rates and fast relief of obstructive symptoms. J~3 However, a stricture of a GJJ and treatment by stent placement has not yet been reported.
