title: A comparison of the periumbilical incision and the intraumbilical incision in laparoscopic appendectomy.
abstract: OBJECTIVE
  The intraumbilical incision is being used more frequently, with increasing cases of single incision laparoscopic surgery. Since the umbilicus is deeper than the surrounding wall, it has abundant bacteria. No study has compared the adverse outcomes of periumbilical and intraumbilical incisions. We analyzed the wound complication rates of perforated appendicitis patients according to the types of umbilical incision.
  
  
  METHODS
  A retrospective review was done of 280 patients with perforated appendicitis. One hundred fifty nine patients were treated with the intraumbilical incision, and 121 patients were treated with the periumbilical incision. We compared the perioperative outcomes according to each laparoscopic incision.
  
  
  RESULTS
  There was no difference in operation time, postoperative hospital stay and analgesic requirement between the two groups. One case in the intraumbilical group (0.6%) and three cases in the periumbilical group (2.5%) developed wound infections. The umbilical complication rate showed no difference.
  
  
  CONCLUSIONS
  The wound complication rate of intraumbilical and periumbilical incisions are not different. Although this retrospective study has inherent limitations, the intraumbilical incision seems to be a safe and feasible alternative for the periumbilical incision that can be easier to perform, with better cosmetic results.
