Comparison of Laparoscopic and Open Pancreaticoduodenectomy on Operative Time, Oncological Outcomes, Bleeding, Morbidity, and Mortality.

Laparoscopic pancreaticoduodenectomy (LPD) has gained popularity as an alternative to open pancreaticoduodenectomy (OPD), but comparative outcomes remain debated. The objective is to perform a systematic review and meta-analysis comparing LPD and OPD on operative time, oncologic outcomes, bleeding, morbidity, and mortality. The inclusion criteria were comparative studies on LPD vs. OPD. Outcomes were pooled using random-effects meta-analysis. A total of 27 studies were included, and LPD had a substantially longer operative duration compared to the OPD procedure, with a mean increase of 56 minutes, but blood loss was reduced by an average of 123 mL in patients who underwent LPD. Morbidity, mortality, margin status, and lymph node yields were similar between LPD and OPD. This study found comparable oncologic outcomes between LPD and OPD. LPD appears safe but requires longer operative time. High-quality randomized trials are still needed.
