Totally Laparoscopic Radical Cholecystectomy for Gallbladder Cancer: A Single Center Experience

Primary laparoscopic approach for the treatment of cancers of the biliary tract is not popular in the surgical community. The aim of this study is to report the short-term data of patients who underwent total laparoscopic radical cholecystectomy for gallbladder cancer (GBC) at a single center of specialized hepatobiliary surgery. From November 2016 to January 2019, we routinely performed a laparoscopic approach for two groups of patients: (1) patients with primary GBC (diagnosed preoperatively) and (2) patients with incidental GBC (IGBC) discovered after cholecystectomy. Our retrospective study included 18 patients (7 primary GBCs, 11 IGBCs). Conversion rate from laparoscopy to laparotomy was 28.6% and 9.1%, respectively, for the two groups, but this difference was not statistically significant (P = .28). Only 3 patients had liver recurrence (27.3%) and 1 had liver invasion (14.3%). A more advanced T category and TNM stage were presented in the preoperative suspicion cases (T3-T4 18.2% versus 57.1%, P = .06, stage IVA-B 9.1% versus 71.4%, P = .017). Regional lymphadenectomy was performed in 15 patients, in 73.3% the total number of lymph nodes (total LNs) retrieved was more than 7 (7-12 LNs in 66.7% of patients and >12 LNs in 6.6% of patients). The mean postoperative long stay was 8 days excluding for cases who developed complication. Laparoscopy can be considered a safe treatment for IGBC or primary GBC. The T3 stage with only liver involvement was not a contraindication. The real reasons that lead to convert the laparoscopic procedure were due to oncological concerns, unrelated to the liver infiltration.
