Laparoscopic procedure for suspected appendicitis. A prospective study in 283 consecutive patients

Between September 1990 and December 1993, 283 consecutive patients were admitted with clinical symptoms of acute appendicitis. These patients underwent primary laparoscopic approach so that an appendicectomy could be performed by this method. In 49 cases (17.3%), primary laparoscopic examination corrected the preoperative diagnosis and the appendix was left in situ. Appendicectomy was performed in 234 cases (149 women, 85 men) with a mean age of 30 years. Requirement for open surgery occurred in 29 cases. The main cause of unsuccessful procedures was inflammation due to local or generalized peritonitis. Median operative time for a successful procedure was 60 min (range, 25-160). Four postoperative complications (one related to laparoscopic procedure), one case of wound infection, and no mortality resulted. After laparoscopic appendicectomy, the median hospital stay was 3 days (range, 1-16). These results suggest that a laparoscopic approach for suspected appendicitis is reliable, allowing abdominal exploration and safe appendicectomy.
