Abstract:
Objective:To explore the feasibility of laparoscopic treatment for incidental gallbladder cancer(IGBCA) and analyze the factors influencing prognosis.
Methods:A retrospective study of 71 patients with IGBCA received laparoscopic treatment at Department of General Surgery, Peking University Third Hospital from January 2007 to December 2016 was conducted,the clinicopathological data and prognosis were analyzed. There were 18 males and 53 females,aged 23 to 81 years. They were divided into two groups based on the presence of intraluminal mass in the gallbladder. Sixty-five of the 71 patients received laparoscopic radical resection, the prognosis of them were compared with 14 patients with open radical resection.
Results:Among the 71 patients,65 patients received radical resection,3 patients simple gallbaldder resection and 3 patients palliative resection. Postoperative complications occurred in 6 patients. IGBCA were detected by frozen section in 57 patients,with the accuracy of 96.5%,while the accuracy of T stage is 43.8% in the 48 patients received T stage evaluation during frozen section examination. The T stages based on final pathology were Tis(n=6),T1a(n=5),T1b(n=10),T2(n=46),and T3(n=4).The number of harvested lymph node was 4.7±2.9(range:2-12).There are 14 patients with lymph node metastasis. The 50 patients with intraluminal gallbladder mass include 21 patients with ≤T1b stage and 29 patients with ≥T2 stage, while the 21 patients without intraluminal gallbladder mass are all with ≥T2 stage. The median survival time of the 71 patients was 33 months, with the 5-year cumulative survival rate 67.3%. The 5-year cumulative survival rate is 78.5% for the 65 patients who received radical resection,comparable with those who received open radical resection(P=0.485).Univariate analysis demonstrated that T stage, lymph node metastasis, G grade, lymphovascular invasion, neural invasion, acute cholecystectomy, bile spillage, gallbladder mass and preoperative CA19-9/CEA were the most important prognostic factors(P<0.05).
Conclusions:Laparoscopic treatment for IGBCA is feasible, especially for those with intraluminal gallbladder mass. The accuracy of frozen section examination in evaluating T stage is low.
