[Laparoscopic "Single-Port" Appendectomy in Children.]

In contrast to the laparoscopic three trocar-technique and to the single incision laparoscopic surgery (SILS), the "single-port" appendectomy (SPA) requires only one port with one integrated instrument channel. We report on our experience with this half-open surgical technique. PATIENTS / MATERIALS AND METHODS: Between September 2006 and August 2008 a total of 285 children underwent an appendectomy, 265 in SPA technique. Through a 10 mm subumbilical inserted ballon trocar, diagnostic laparoscopy was routinely performed and, afterwards, the appendix was grasped with a 450 mm forceps, exteriorised and dissected outside the abdomen as in open surgery. Patients with perforated appendicitis detected by preoperative ultrasonography were operated by open appendectomy.
