Abstract
INTRODUCTION: Acute pancreatitis after surgical treatment of non ruptured aneurysm of abdominal aorta is a rare complication, considered to be due to pancreatic ischemia or peroperative trauma of pancreas. The aim of this study is to describe 4 new cases of this complication and to discuss its etiology. PATIENTS AND METHODS: From January 1995 to November 2000, 365 patients underwent elective surgery for a non ruptured abdominal aorta aneurysm. Four (1.1%) men, aged 66 to 79 years and operated for an aneurysm which diameter ranged from 60 to 77 mm, developed postoperative acute pancreatitis. The abdominal approach was a midline incision in 3 cases and a retroperitoneal lombotomy in one case. Superior pole of the aneurysm always adjoined or involved the right renal artery. The aortic clamping was supra-renal in 3 cases and celiac in one case. Diagnosis of acute pancreatitis was established at days 2, 4, 12, and 23 after surgery on abdominal computed tomography in 3 cases and at reoperation in one case. RESULTS: Three patients died, including 2 from early multiple organ failure and one peroperatively during surgical attempt to treat a prostheto-digestive fistula. One patient was alive and asymptomatic with a 2-years follow-up. CONCLUSION: Acute pancreatitis is a rare and serious complication after surgical treatment of abdominal aorta aneurysm. Its diagnosis is often delayed. The main etiological factor of this complication could be trauma of pancreas during supra-renal clamping through a midline incision.
