Central pancreatectomy, as an alternative to standard resection for benign and low-grade pancreatic neoplasms, has been described in mainly small retrospective series.
To describe a large single-center experience with central pancreatectomy.
Design, Setting, and Participants
A retrospective case series in a tertiary referral center included 100 consecutive patients undergoing central pancreatectomy with pancreaticogastrostomy from January 1, 2000, to March 1, 2012.
Main Outcomes and Measures
Surgical indications, postoperative morbidity, mortality, and long-term outcomes regarding pancreatic function and recurrence.
Central pancreatectomies were performed mainly for neuroendocrine tumors (35%), intraductal papillary mucinous neoplasms (33%), solid pseudopapillary neoplasms (12%), and mucinous cystadenomas (6%). The postoperative mortality rate was 3% (due to pulmonary embolisms in 2 patients and hemorrhage after pancreatic fistula in 1 patient). Clavien-Dindo III or IV complications occurred in 15% of patients and were due mainly to pancreatic fistula, requiring 10 radiologic drainage procedures, 7 endoscopic procedures, and 6 reoperations overall. After a median follow-up of 36 months, the rates of new-onset exocrine and endocrine insufficiency were 6% and 2%, respectively. Overall, 7 lesions could be considered undertreated, including 3 node-negative R0 microinvasive intraductal papillary mucinous neoplasms (without recurrence at 27, 29, and 34 months) and 4 node-positive neuroendocrine tumors (with 1 hepatic recurrence at 66 months). Among the 25 patients with a doubtful preoperative diagnosis, 9 could be considered overtreated (ie, operated on for benign nonevolutive asymptomatic lesions).
Conclusions and Relevance
Central pancreatectomy is associated with an excellent pancreatic function at the expense of a significant morbidity and a non-nil mortality rate, underestimated by the published literature. The procedure is best indicated for benign or low-grade lesions in young and fit patients who can sustain a significant postoperative morbidity and could benefit from the excellent long-term results.
