Objective To explore the effects of bile from patients with cholecystolithiasis on the growth of human gallbladder carcinoma cells GBC-SD and the potential correlation between cholecystolithiasis and gallbladder carcinoma. Methods Cholecystolithiasis bile (CB) and normal bile (NB) specimens were used for this study. The proliferative effects of bile were measured by methabenzthiazuron (MTT) assay and cell cycle and apoptosis were analyzed by flow cytometry. Results CB can significantly promote the proliferation of GBC-SD cells, GBC-SD proliferative index increased significantly after treated with 1% CB for 48 h （P＜0.05）.The Sphase fraction of CB 〔（49.26±8.07）%〕 increased remarkably (P＜0.05) compared with that of NB 〔（25.54±6.57）%〕, and the CB percentage of G0/G1 phase 〔（40.59±9.12）%〕 decreased remarkably (P＜0.05) compared with NB 〔(60.64±13.42）〕%. Conclusion CB can promote the proliferation of human gallbladder carcinoma GBC-SD cells.
Objective To explore the effect of gallbladder preserving surgery with laparoscope and choledochoscope.Methods The data of 60 cases of gallbladder preserving surgery with laparoscope and choledochoscope （observation group） and carried out with the same period 61 cases of small incision gallbladder preserving surgery （control group） between June 2008 to January 2013 were retrospective analyzed. Results All patients were followed up for （18±2.4）months （6-36 months）. The intraoperative blood loss， postoperative gallbladder hemorrhage rate， gallbladder dysfunctionrate， postoperative hospitalization time， stone recurrence rate， and reoperation rate in observation group were less orlower or shorter than the control group （P＜0.05）. The operative time and hospital costs in observation group were longeror higher than that of the control group （P＜0.05）. The rest of the observation index of two groups were no significant differences （P＞0.05）. Conclusions The gallbladder preserving surgery with laparoscope and choledochoscope is safeand feasible in technique level， and the short-term effect after operation is better. But the operation indications must be controlled strictly. The long-term efficacy needs further accumulation of cases and collect enough evidence to verify.
