Abstract
Background The aim of this study was to validate the safety and feasibility of pure laparoscopic extended cholecystectomy (LEC) by comparing the outcome with that of open extended cholecystectomy (OEC). Moreover, on the basis of our experience, we also aimed to investigate the learning curve of pure LEC. Methods This single-center study enrolled patients who were diagnosed primary gallbladder cancer with pathologically confirmed and underwent R0 resection with curative intent between January 2016 and December 2019. A total of 31 patients who underwent OEC and 17 patients who underwent LEC were selected. Propensity score matching analysis was performed in a 1:1 ratio using the nearest-neighbor matching method, and clinical information was retrospectively collected from medical records and analyzed. Results The postoperative hospital stay was statistically shorter in the LEC group (7 days) than in the OEC group (12 days). The overall surgical complication rate did not differ between the two groups. The 1- and 3-year disease-free survival rates were 82.4% and 82.4% in the OEC group and 94.2% and 71.5% in the LEC group, respectively (P = 0.94). Considering the correlation between the number of cumulative cases and the operation time and between the number of cumulative cases and the number of retrieved lymph nodes in the LEC group, as the cases were accumulated, both the operation time and the number of retrieved lymph nodes had a statistically significant correlation with the number of cases. Conclusions LEC showed a significant advantage in terms of achieving shorter postoperative hospital stay and similar results to OEC with respect to overall complications and pathological outcomes. The present results confirm that laparoscopy can be considered a safe treatment for primary gallbladder cancer in selected patients.
