A prognostic analysis of laparoscopic versus radical cholecystectomy for T1b unsuspected gallbladder carcinoma / 临床肝胆病杂志

ABSTRACT

ObjectiveTo investigate the surgical treatment and prognosis of T1b unsuspected gallbladder carcinoma (UGC). MethodsTwenty-two patients with T1b UGC admitted to our hospital were enrolled as subjects. The information on clinical pathology, radiological examination, laboratory tests, surgical treatment, and postoperative follow-up were analyzed in patients. The survival rate and recurrence were compared between patients treated with radical cholecystectomy and laparoscopic cholecystectomy. The Kaplan-Meier method was used to calculate survival rates, and the log-rank test was used for survival difference analysis. Comparison of categorical data was made by Fisher′s exact test. ResultsThe 1-, 3-, and 5-year accumulative survival rates in all patients with T1b UGC were 100%, 89.7%, and 82.8%, respectively; there was no significant difference in the 5-year accumulative survival rate between patients treated with laparoscopic cholecystectomy and radical cholecystectomy (84.6% vs 75.0%, χ2=0.000, P=0.991); two (15.4%) out of thirteen patients treated with laparoscopic cholecystectomy respectively; one (12.5%) out of eight patients treated with radical cholecystectomy had recurrence, there was no significant difference between the two groups(P＞005). ConclusionRadical cholecystectomy is a superior therapy for T1b UGC over laparoscopic cholecystectomy.
