Abstract: Objective To explore the effect of fluorescence laparoscopy on the recognition of gallbladder triangle during cholecystectomy and its clinical application.
Methods A retrospective analysis of 130 cases of laparoscopic cholecystectomy(LC) was performed.The patients were divided into two groups:Group A(87 cases) and Group B(43 cases),the intraoperative and postoperative complications of the two groups were statistically analyzed.
Results All 130 patients underwent laparoscopic cholecystectomy without conversion to open surgery.In Group A,the operation time(69.75±25.64) Min,intraoperative blood loss(4.40±4.02)ml,hospital stay(4.49±1.01)D,extubation time(3.15±0.83)D,there were 5 patients with postoperative complications.The operation time(72.33±29.14) Min,intraoperative bleeding(4.19±2.83)ML,hospital stay(4.42±0.88) D and extubation time(3.09±0.72) D in Group B,no postoperative complications were found.There was no significant difference between the two groups(P>0.05)，there were no drug allergy and other drug-related complications during indocyanine green angiography.
Conclusion The application of Indocyanine Green(ICG) in laparoscopic cholecystectomy is helpful to judge the anatomy of biliary tract and has no effect on the operation time and postoperative complications,which increased the safety of surgery.
