Insights

Single-incision laparoscopic appendectomy (SILA) in children shows a higher wound infection rate and longer operative time compared to conventional multiport laparoscopic appendectomy (CLA). SILA is feasible but not superior, suggesting it may not be the preferred approach for pediatric appendectomies.

Area of Science:

  • Pediatric Surgery
  • Minimally Invasive Surgery
  • Gastrointestinal Surgery

Background:

  • Single-incision laparoscopic appendectomy (SILA) is increasingly used in adults with outcomes comparable to conventional multiport laparoscopic appendectomy (CLA).
  • The application and comparative efficacy of SILA versus CLA in pediatric patients remain controversial.
  • A lack of systematic reviews comparing SILA and CLA in children necessitates further investigation.

Purpose of the Study:

  • To systematically compare the safety and efficacy of SILA versus CLA in pediatric appendectomy.
  • To evaluate key postoperative outcomes, including complications, operative time, and hospital stay.

Main Methods:

  • A comprehensive literature search was conducted across major databases (MEDLINE, EMBASE, Cochrane, ClinicalTrials.gov) from January 1998 to September 2014.
  • Included studies involved pediatric patients undergoing either SILA or CLA for appendectomy.
  • Meta-analysis utilized a random effects model to assess primary outcomes (complications, wound infection, abscess, ileus, hematoma) and secondary outcomes (operative time, hospital stay, analgesic use).

Main Results:

  • The meta-analysis included 14 studies with 2249 pediatric patients (744 SILA, 1505 CLA).
  • No significant differences were found in overall postoperative complications, intra-abdominal abscess, ileus, wound hematoma, hospital stay, or analgesic use.
  • SILA was associated with a significantly higher incidence of wound infection (OR=2.25) and a longer operative time (WMD=5.73 minutes) compared to CLA.

Conclusions:

  • Single-incision laparoscopic appendectomy (SILA) is a feasible procedure in pediatric patients but does not offer superiority over conventional multiport laparoscopic appendectomy (CLA).
  • The increased risk of wound infection and longer operative time associated with SILA suggest it may not be the optimal surgical approach for pediatric appendectomies.
  • Further research may be warranted to refine SILA techniques or identify patient subgroups who might benefit.
