Perforated appendicitis--the Malaysian experience.

Perforated appendicitis, with its increased complication rate, today still poses a formidable problem in the Kuala Lumpur General Hospital. Out of 1694 emergency operations performed by our unit in 1987, there were 927 appendicectomies. A retrospective study of these cases showed 126 cases of perforated appendicitis, which were then subjected to detailed analysis. We have a diagnostic accuracy of 81% and perforation rate of 18%. In addition, it is interesting to note the racial differences in the relationship of diagnostic accuracy to perforation rate. Perforation is associated with an increased wound infection rate. Transperitoneal drainage in perforated appendicitis did not lead to a lower incidence of wound infection or improve postoperative performance. Distinguishing between perforated and non-perforated appendicitis may be difficult. Perforation could occur while awaiting operation. We recommend the early administration of systemic antibiotics should appendicectomy be delayed and the cautious use of drains in cases of perforated appendicitis.
