Laparoscopic resection of the pancreas and review of the literature

BACKGROUND: Laparoscopic pancreatic surgery still is not a common procedure worldwide. Postoperative complications such as a pancreatic leakage cause a serious condition. We report our consecutive laparoscopic pancreatic resections of islet cell tumors or benign diseases and their outcomes. METHOD: Laparoscopic pancreatic resections were attempted in three patients. Preoperative diagnoses were insulinoma in two patients and cystadenoma in one patient. The lesions were located in the pancreas body in two patients and the pancreas tail in one patient. Their sizes ranged from 1 to 6 cm in diameter (mean, 3 cm). RESULTS: We performed distal pancreatectomy using an endoscopic linear stapler with conservation of the spleen in two patients and enucleation in one patient. Of the distal pancreatectomies, the splenic artery and vein were preserved in one patient, whereas in the other they were divided. There were no perioperative complications in any of the cases. The mean postoperative hospital stay was 10 days (range, 7-14 days). There were no episodes of hypoglycemia or recurrence during the mean follow-up period of 25 months (range, 11-36 months). CONCLUSIONS: Although laparoscopic pancreatic resection of selected patients is a feasible and safe procedure in the hands of experienced laparoscopic surgeons, patients must be carefully observed after surgery to avoid serious conditions by pancreatic fistula.
