Laparoscopic central pancreatectomy for solid pseudopapillary tumors of the pancreas: our experience with ten cases

BACKGROUND Solid pseudopapillary tumors (SPTs) of the pancreas are a rare neoplasm. There are few reports of laparoscopic central pancreatectomies (LCPs) for SPT of the pancreas. The objective of this study was to evaluate the feasibility, safety and long-term outcome of LCP based on a series of SPT patients. METHODS This retrospective study included ten patients who underwent LCP between 2009 and 2013. Clinical characteristics and intra- and postoperative data were retrospectively analyzed. A follow-up of at least 3 months was available for all patients. RESULTS All procedures were successfully performed laparoscopically, and no patient required intraoperative blood transfusion. The median operative time was 271 min (range 250 to 310 min) and the median loss of blood was 104 ml (range 80 to 150 ml). The mean tumor size was 51 mm (range 38 to 62 mm). All patients underwent complete resection with negative surgical margin. An average of 5.8 lymph nodes were resected without metastases. The median first flatus time was 2 days, and the median starting time for diet was 3 days. The median postoperative hospital stay was 13 days (range 10 to 23 days). Morbidity was 20%. The median follow-up was 22.9 months (range 3 to 48 months), at which point all patients were alive with no recurrence. None of the patients developed exocrine or endocrine insufficiency. No hospital mortalities occurred in our patient group. CONCLUSIONS LCP is a safe and effective technique for resecting SPT of the neck and proximal body of the pancreas while preserving pancreatic endocrine and exocrine function, and the spleen.
