One-step surgery for acute ischemia of the jejunal loop after pancreatoduodenectomy: report of a case.

BACKGROUND Pancreatoduodenectomy (PD) is an extensive surgery, and its complications are grave. Acute ischemia of the jejunal loop due to thrombosis of the superior mesenteric vein (SMV) and its branches is one of the most dangerous complications that, although rare, if left untreated leads to abdominal sepsis and death of a patient. CASE PRESENTATION A 77-year-old man underwent PD for pancreatic cancer. On postoperative day 2, the patient developed a severe anemia with hypotension. The computed tomography showed acute ischemia of the jejunal loop due to thrombosis. The emergent surgery was performed. The removal of the ischemic intestine and re-anastomoses of the biliary and pancreatic ducts could be performed all at once because necrosis and inflammation were still very mild in early stage. CONCLUSION If suspicion for thrombosis of the SMV and its branches is raised, re-laparotomy should be considered. Early re-operation can lead to removal of the ischemic intestine and re-anastomoses in one-step surgery.
