IntroductionSingle-incision pediatric endosurgery (SIPES) has gained popularity for ablative procedures such as appendectomy in many pediatric surgical centers. This study evaluates the outcome of SIPES for treatment of appendicitis in our institution.Patients And MethodsAfter Institutional Review Board approval was obtained, data were prospectively collected on all patients undergoing SIPES appendectomy in our hospital from March 2009 through October 2011. The surgical techniques, operative times, complications, conversion rates, and outcomes were recorded.ResultsSIPES appendectomy was attempted in 415 children (mean age, 10.9 years; age range, 1.4-17.9 years; 266 males, 149 females; median weight, 43 kg; weight range, 9.8-146 kg). Intraoperatively, acute appendicitis was found in 298 cases and perforated appendicitis in 79 cases. Thirty-eight patients underwent interval appendectomy. Appendectomy was carried out solely as SIPES in 397 cases (96%). Median operative time was 40±16 minutes (37±16 minutes for fellows [n=284] and 46±15 minutes for residents [n=131]). There were three intraoperative complications, which could be handled during the procedure. Pathologic reports revealed inflammatory changes of the appendix (n=386), other pathology (n=11), and no pathologic change (n=18). Overall, 24 patients (5.8%) were readmitted for intra-abdominal abscess (n=14), umbilical wound infection (n=3), and other reasons (n=7). Twelve patients (2.9%) underwent reoperation: drainage of intra-abdominal abscess (n=8) (3 by the surgeon, 5 by the interventional radiologist), wound drainage (n=3), and right hemicolectomy for carcinoid (n=1). In perforated appendicitis the postoperative intra-abdominal abscess rate was 10 of 79 cases (12.7%), which is similar to the previous report with conventional laparoscopic appendectomy from our institution (13.6%). The wound infection rate (5 of 79 cases [6.3%]) was also similar to the previously report (6.8%) with conventional laparoscopic appendectomy for perforated appendicitis.ConclusionsAppendectomy can be accomplished successfully and safely using single-incision endosurgery in children with acceptable operative times without leaving any appreciable scar. Additional trocars are infrequently necessary. So far, the intraoperative and postoperative complication rates are comparable to those of triangulated laparoscopic appendectomy.
