Iatrogenic transmesenteric defect mimicking a Petersen’s space hernia after open pancreatic necrosectomy

Abstract

Abstract Complications of acute pancreatitis can be disastrous if appropriate treatment is not initiated. Pancreatic necrosis can occur without the presence of symptoms; however, in some cases, it can be accompanied by organic failure, abscess, pseudocyst, fistulas, and pancreatic exocrine disfunction. The surgical treatment of pancreatic necrosis can be managed with open surgical debridement of necrotic tissue. Hence, complications after surgery can appear even in patients without clinical background; complications mostly appear if the surgical technique is not done properly. We present a case of a 47-year-old woman who appeared with abdominal pain, nausea, vomiting, and oral intake intolerance. Symptoms were present for 1 week; she was admitted to the nearest clinic, and surgical management was offered. The patient went to an open pancreatic necrosectomy; however, she presented purulent exudate from the surgical wound and drains. Was referred to our center; on abdominal contrasted computed tomography, a transmesenteric defect and cutaneous-pancreatic fistula were found.
