Gasless Laparoscopic Cholecystectomy in a Pig Using a Self-Designed Umbrella-Like Abdominal Wall-Lifting Device

Abstract

Abstract Introduction: In laparoscopic surgery with CO2 pneumoperitoneum, serious complications often occur for elderly patients and those who undergo long operations.1 These complications mainly include respiratory and circulatory system changes.2–4 In patients with tumors, release of free tumor cells into the abdominal cavity is believed to be possible.5 Gasless laparoscopic techniques can avoid these complications of CO2 pneumoperitoneum. Currently, the main shortcoming of gasless laparoscopic techniques is the inadequate operative space. Because of this shortcoming, gasless techniques have not been widely applied in clinical practice. Case Report: In the video, we describe a new technique of gasless laparoscopic cholecystectomy in a pig using a self-designed umbrella-like abdominal wall-lifting device. The umbrella was constructed from stainless steel and was 150 mm in diameter. Ten spokes formed an umbrella through a folding movement. This device lifted up the anterior abdominal wall by opening the u...
