PERITONEOSCOPIC CHOLECYSTECTOMY HAS OPENED THE DOOR TO MINIMALLY INVASIVE SURGERY

In 1989 a new trend occurred in the surgical treatment of a diseased gall-bladder, laparoscopic cholecystectomy (LC). Laparoscopic surgery is now accepted world-wide as the choice of treatment with the advantages of less pain, good cosmesis, short hospital stay and early recovery. It is also a curative procedure for cholelithiasis as well as a cholecystectomy. The rate of conversion to open surgery is about 5% and the rates of bile duct injury are 0.1-0.6%. This new approach revives controversies concerning cholecystectomy; namely indication, use of intra-operative cholangiography, ductal calculi and pregnancy. There are new issues to consider, including use of a Veress needle for pneumoperitoneum, type of trocars, cardiovascular responses to pneumoperitoneum using carbon dioxide and so on. With increasing use, these difficulties will be overcome. Advances in technology are expected to make even more new types of surgery possible, even perhaps extending into robotic surgery.
