Laparoscopic pancreaticoduodenectomy: technique and outcomes.

BACKGROUND: We describe our experience with laparoscopic pancreaticoduodenectomy, including 5-year actuarial survival rates. STUDY
DESIGN: This is a retrospective study of selected patients who underwent laparoscopic pancreaticoduodenectomy at a single center between 1998 and 2006. We have described the salient features of our technique and followup protocol. Patient characteristics, histologic variety of the tumor, resection margins, morbidity, mortality, and actuarial survival rates were studied.
RESULTS: The procedure could be completed laparoscopically with tumor-free margins in all patients, including patients with ampullary carcinoma (n = 24), pancreatic cystadenocarcinoma (n = 4), pancreatic head adenocarcinoma (n = 9), low common bile duct cancer (n = 3), and two patients with chronic pancreatitis with a suspicious mass lesion in the head of pancreas. Mean age of patients was 61 years (range 28 to 70 years). There was a single perioperative mortality. Overall followup rate was 95.1%, with two patients lost to followup at 22 and 36 months. Among the survivors, two patients have metastatic disease and local recurrence developed in one patient. Five-year actuarial survival rates for all patients with malignancy, ampullary adenocarcinoma, pancreatic cystadenocarcinoma, pancreatic head adenocarcinoma, and common bile duct adenocarcinoma are 32%, 30.7%, 33.3%, 19.1%, and 50%, respectively. Presence of microscopic lymph node involvement is associated with poor survival, although operations in the setting of chronic pancreatitis resulted in increased morbidity.
CONCLUSIONS: Laparoscopic pancreaticoduodenectomy can be performed with safety and good results in properly selected patients. Localized malignant lesions, irrespective of histopathology, are particularly amenable to this approach.
