In an initial stage of introducing laparoscopic appendicectomy, 233 patients with indication for surgical treatment were evaluated in an open prospective trial. Surgery was done by a total of 39 trainees on duty. The procedure was started as a diagnostic laparoscopy followed by laparoscopic appendicectomy if the appendix was macroscopically inflamed. If the appendix was normal, it was left in place. There were 51 patients with a macroscopically normal appendix. Subsequently, none of them suffered from appendicitis or any other disorder requiring surgery. In 182 patients with laparoscopically assessed inflamed appendix, laparoscopic appendicectomy was attempted. One hundred and forty-eight proved successful, whereas 34 were converted to an open operation, mainly because of limited experience with the laparoscopic technique. Wound infection occurred in two and intraperitoneal abscess in four patients (0.9% and 1.7%), respectively. There was only one complication (0.4%) directly related to the laparoscopic procedure, namely a coecal leak. In conclusion, in a teaching hospital, laparoscopic appendicectomy can be safely offered to patients where surgery is indicated due to suspicion of appendicitis.
