Abstract:

Our team frequently confronts problems such as inadequate exposure and time-consuming adjustment during single-port laparoscopic cholecystectomy.Recently，our team has employed T-shaped shape memory alloy wires in single-port laparoscopic cholecystectomy，which entails penetrating the basal layer of the gallbladder and the mesothelium of the cystic duct to pull the gallbladder at different angles for enhanced exposure.This procedure is denominated the marionette single-port laparoscopic cholecystectomy.With the assistance of this instrument，the operation becomes less arduous，the exposure effect is more pronounced，and in comparison with the conventional single-port laparoscopic liver resection，it adds three 1.1mm port holes.The assistant port heals without leaving scars，and its postoperative aesthetic outcome is comparable to that of conventional single-port laparoscopic surgery，and even the umbilical incision is smaller.This video showcases the marionette single-port laparoscopic cholecystectomy，which is a suitable technique worthy of promotion.
