BACKGROUND

Transumbilical laparoscopic-assisted appendectomy (TULA) is a single incision technique that exteriorizes the appendix through the umbilicus. The aim of this study was to compare the surgical outcomes of TULA with SILA in pediatric appendicitis.

METHODS

A retrospective review of medical records between April 2011 and April 2015 identified 250 pediatric patients who underwent single incision laparoscopic appendectomy. Of these, 137 patients underwent TULA and 113 patients underwent SILA. Measured outcomes included patients' demographics, clinical characteristics, operative time, length of stay, pain, and postoperative complications.

RESULTS

TULA group had a shorter operative time than SILA group (28.93 vs. 49.19min, p<0.001). The use of rescue analgesics was more frequent in the SILA group (six cases (6.5%) vs. 19 cases (23.4%), p<0.001). There was no significant difference in cosmetic outcome between the two groups. However, TULA was associated with a lower complication rate (2/137, 1.5%) than SILA (11/113, 9.8%) (p=0.0035). In multiple logistic regression analysis, TULA was significantly associated with a lower complication rate (p=0.049).

CONCLUSIONS

TULA is preferable to SILA for treating pediatric acute appendicitis because it is technically easier, results in better surgical outcomes, and provides the same excellent cosmetic results.
