Pancreatic redo procedures: to do or not to do -- this is the question.

BACKGROUND: Pancreatic redo procedures belong to the most difficult abdominal operations because of altered anatomy, significant adhesions, and the potential of recurrent disease. We report on our experience with 15 redo procedures among a series of 350 consecutive pancreatic operations. PATIENT AND METHODS: From January 1, 2004 to May 31, 2006 a total of 350 patients underwent pancreatic surgery in our department. There were 15 patients identified who had pancreatic redo surgery for benign (14) or malignant (1) disease. Perioperative parameters and outcome of 15 patients undergoing redo surgery after pancreatic resections were evaluated.
RESULTS: Operative procedures included revision and redo of the pancreaticojejunostomy after resection of the pancreatic margin (6), completion pancreatectomy (3), conversion from duodenum-preserving pancreatic head resection to pylorus-preserving pancreaticoduodenectomy (3), classic pancreaticoduodenectomy after nonresective pancreatic surgery (1), redo of left-sided pancreatectomy (1), and classic pancreaticoduodenectomy after left-sided pancreatectomy (1). Histology revealed chronic pancreatitis in 14 and a mucinous adenocarcinoma of the pancreas in 1 patient. Median operative time was 335 min (235-615 min) and median intraoperative blood loss was 600 ml (300-2,800 ml). Median postoperative ICU stay was 20 h (4-113 h) and median postoperative hospital stay was 15 days (7-30 days). There was no perioperative mortality and morbidity was 33%.
CONCLUSION: Pancreatic redo surgery can be performed with low morbidity and mortality. Redo surgery has a defined spectrum of indications, but to achieve good results surgery may be performed at high-volume centers.
