Laparoscopic appendectomy in children: evaluation of different techniques.

Patients and surgeons frequently opt for laparoscopic appendectomy for treatment of acute appendicitis. Clinical studies have shown this approach to be a reasonable alternative to open appendectomy. The objective of the current study was to assess the outcome of laparoscopic appendectomy using three different techniques. The study sample consisted of 150 children with acute appendicitis who underwent surgery at Al-Azhar University Hospitals, Cairo, Egypt, and at Al Mishary Hospital in Riyadh, Saudi Arabia, between October 1997 and October 1999. The patients were allocated to undergo extracorporeal laparoscopic appendectomy, Endoloop laparoscopic appendectomy, or EndoGIA (Ethicon Endo-surgery, Inc., Cincinnati, OH, USA) laparoscopic appendectomy. All patients were assessed for the severity of the disease at baseline using clinical and hematologic indicators. The ages of the children ranged from 7 to 14 years, with a mean of 10 years (SD, 2.14 years). Of the children, 55.3% were female. The results showed that children who underwent laparoscopic appendectomy using the EndoGIA had statistically significant shorter operating times, did not have complications, and had the shortest duration of hospital stay (although duration of hospital stay did not reach the statistically significant level of P > 0.05). Therefore, the study showed that laparoscopic appendectomy using the EndoGIA is the procedure that is most recommended, except for the relatively high cost of the disposable materials. Endoloop laparoscopic technique was the second most preferable procedure, and the least preferred procedure was extracorporeal laparoscopically assisted appendectomy. The major drawback of the last technique is the high frequency of complications. Endoloop laparoscopic appendectomy with a purse-string suture can be performed safely if the EndoGIA is not available.
