Robot-assisted vs Laparoscopic vs Open Radical Cholecystectomy for Gallbladder Cancer

The gallbladder is the most common primary cancer site among the biliary tracts and its incidence is increasing. Its prognosis is still poor with a 5-year survival of almost 20%. Cholecystectomy is curative in patients with Tis and T1a. For patients with resectable T1b and above disease, radical cholecystectomy is advocated consisting of en bloc resection of the gallbladder, wedge resection of the liver or segment 4b, extrahepatic bile duct, and the regional lymph nodes. The aim of this study is to compare patients who have undergone Robotic, Laparoscopic and Open liver resection with lymphadenectomy for \>T1b gallbladder cancers in a case-matched analysis using propensity scores. The primary endpoints are intra- and postoperative outcomes, and the secondary endpoints long-term oncologic outcomes and feasibility and adequacy of minimally invasive versus traditional open approach.
