Abstract
This study aimed to assess the outcome after intracorporeal (IC) and extracorporeal (EC) laparoscopic appendectomy technique in a single institution over a 5-year period. Records of all children (n = 60) who underwent laparoscopic appendectomy at the Royal Aberdeen Children’s Hospital between February 1997 and March 2002 were retrieved and evaluated. Observations were made regarding operative technique, anesthetic time, intra- and postoperative complications, postoperative analgesic requirement, and postoperative hospital stay. There were 30 children in each group who had a similar demographic profile. The magnitude of appendicitis severity in both groups was similar. The mean anesthetic time was 67.8 min for the IC group and 50.7 min for the EC group (p = 0.001). There were no recorded intraoperative complications, although a single case in the EC group required conversion to open procedure. The postoperative analgesic requirement in both groups was similar. The mean postoperative stay was 2.1 days in the IC group and 2.5 days in the EC group. Two postoperative complications were noted in the IC group; one intraperitoneal collection and one postoperative chest infection. Four complications occured in the EC group; one intraperitoneal collection and three minor port-site wound infections. The authors’ experience shows the EC technique to be significantly quicker, although with a slightly increased complication rate. Either technique can be applied safely for acute appendicitis.
