We report surgical techniques for single-incision laparoscopy-assisted surgery (SILAS) in the treatment of pediatric acute appendicitis. We performed SILAS in 15 cases of acute appendicitis between January and September of 2009. SILAS is a surgical method that involves making the incision at the umbilicus, inserting a wound retractor XS, suspending the abdominal wall with a hook, and appendectomy with the same procedures as conventional appendectomy. SILAS appendectomy was performed in all 15 cases with the exception of one case where one 3-mm port was added. Compared to open appendectomy, blood loss was significantly lower and postoperative hospitalization time was shorter, although there was no significant decrease in operative time, or postoperative fasting time. No postoperative complications, such as wound infection, intestinal obstruction, intra-abdominal abscess, or bleeding, were encountered. SILAS was safely performed and is superior to open appendectomy with regard to cosmetic outcome.
