RESUMO
Liver surgery has entered the era of precision surgery. Therefore, how to optimize the resection of lesions and reduce the unnecessary time of liver ischemia and hypoxia have become the focus. A total of 11 patients who underwent fluorescence laparoscopic liver mass resection and preoperative three-dimensional (3D) reconstruction between August 2018 and July 2020 were evaluated. Liver cirrhosis occurred in 3 patients. The mean intraoperative blood loss was 166.8 ± 105.7 mL. The average length of the operation time was 152.0 ± 45.3 minutes. The average intraoperative hilar occlusion time was 9.3 minutes (except for hilar cholangiocarcinoma). The liver function of all patients, except patients with hilar bile duct carcinoma, returned to the preoperative level at 72 hours, and no serious complications occurred. 3D reconstruction combined with fluorescence laparoscopic imaging is safe and effective for precision liver resection.

The safety and efficacy of the combination of electronic choledochoscopy and holmium laser lithotripsy for complicated bile duct stones were assessed. In total, 20 patients participated in this study, which was conducted between 2012 and 2017. None of the patients were candidates for endoscopic retrograde cholangiopancreatography with stone extraction. Outcome measures included complete stone clearance and complications postprocedure. Mean stone size was 17±5.2 mm (8 to 30 mm) and mean number of stones was 1.7±1.3 (1 to 5). The mean number of laser sessions was 1.3±0.7 (1 to 4). A mean of 1.0 to 1.5 J/20 to 25 Hz was applied during laser lithotripsy sessions with a mean operative time of 67.8±24.8 minutes. The clearance rate of stone was 18/20 (90%). No mortality existed in this study; however, 1 patient developed acute pancreatitis. The combination of holmium laser lithotripsy and electronic choledochoscopy for complicated biliary calculi is safe, reliable, and minimally invasive and has low residual stone rate.
