The analysis of pancreatic fistula in middle segmental pancreatic resection

Objective To analyze the influence of pancreatic fistula in middle segmental pancreatic resection and summarize the experience in dealing with the stump. Methods The data of 40 cases undergoing middle pancreatectomy were reviewed retrospectively to analyze the curative effect and pancreatic fistula between April 2003 and December 2009. Of these, 36 patients with benign cases outcomes were compared with 2 separate control groups, 44 pancreaticoduodenectomy (PD) and 26 extended distal pancreatectomy (EDP). Results The mean operating time of group MSP was 222 min, which was significantly shorter than that of group PD. The mean blood loss of group MSP was 316 ml,which was less than that of others. Otherwise, the postoperative nutritional status and blood sugar control in group MSP was superior to the other 2 groups. Through long-term follow-up,the patients in group MSP retained endocrine and exocrine function better. Only 1 patient developed new-onset diabetes mellitus after operation, and no patient required enzyme substitution. No lesion recurred. The rate of pancreatic fistula was highest(42％) ,but didn't result in the significant deference of overall discharge time with group PD and EDP. The pancreatic fistula level and the mean postoperative time in hospital didn't differ significantly from the other 2 groups.Conclusions Middle segmental pancreatectomy is a safe and feasible technique that is indicated for selected patients with benign or low malignant lesion in the neck and body of the pancreas. Though the rate of pancreatic fistula is higher,the risk of which is reduced by the marked curative effect It is very important to deal with the stump reasonably.
