Outcome of laparoscopic pancreatic surgery: endocrine and nonendocrine tumors.World J Surg. 2002 Aug; 26(8):1057-65.WJ
Laparoscopic pancreatic surgery (LapPS) for management of benign pancreatic tumors has still not been defined. This paper evaluates the feasibility and outcome of LapPS in patients with endocrine pancreatic tumors (EPTs) and cystic neoplasms of the pancreas (CyNP). Eighteen patients with benign pancreatic tumors underwent LapPS between January 1998 and May 2001. The indications were 10 EPTs (6 sporadic insulinomas, 1 multiple insulinoma of multiple endocrine neoplasia type 1, 2 nonfunctioning tumors, 1 VIPoma) and 8 CyNPs (3 serous cystadenomas, 5 mucinous cystic neoplasms). The laparoscopic procedure was performed using four ports with patients in the half-lateral position. Laparoscopic ultrasonography (LapUS) was used in all cases. Laparoscopic enucleation (LapE) was planned in five patients and performed in four (one conversion for tumor not found during laparoscopy). Laparoscopic pancreatic resection (LapPR) with spleen salvage was planned in 13 patients and performed in 12 (one conversion for metastatic VIPoma), with splenic vessel preservation in 11 patients and short gastric vessel preservation in 1. The average operating time was 3.5 hours after enucleation, 4.0 hours after distal pancreatectomy, and 5.0 hours after subtotal pancreatectomy. Pancreatic fistula was observed in two patients after LapE and in three patients after LapPR. Splenectomy for splenic abscess was performed 1 week after surgery in a patient with short gastric vessel splenic preservation. The average hospital stay was 5 days. We concluded that LapPS is a safe method for removing EPTs and CyNPs, although the incidence of pancreatic fistulas remains high. In selected patients LapPS offers significant benefit to patients: reduced trauma to the abdominal wall, short hospital stay, and a quick postoperative recovery.
