Perforated ulcer at the gastrojejunal anastomosis: a rare complication of pancreaticoduodenectomy (case report).

Pancreaticoduodenectomy (PD) is recognized as one of the most intricate abdominal surgical procedures, often accompanied by high morbidity rates. The occurrence of an anastomotic ulcer at the gastrojejunal anastomosis post-pancreaticoduodenectomy surgery is a relatively uncommon complication, albeit potentially leading to severe, life-threatening consequences. The predominant symptomatology manifests as acute abdominal pain accompanied by peritonitis. Conventionally, diagnosis is achieved through computed tomography (CT) scans, facilitating subsequent management, and surgical management is recommended in the majority of instances. Herein, we present a rare case of a patient who experienced ulcer perforation at the gastrojejunal anastomosis site after undergoing pancreaticoduodenectomy with stomach preservation, and we reviewed the available literature to gain more comprehension of this rare complication of this type of surgical intervention.
