Trans-umbilical laparoscopic-assisted appendectomy in the pediatric population: comparing single-incision and 2-trocar techniques.
INTRODUCTION: Trans-umbilical laparoscopic-assisted appendectomy (TULAA) combines advantages of open surgery with benefits of laparoscopy and can be performed either by single-incision or with two trocars; the present study aims to compare outcomes and cost of these techniques in a pediatric serie.
MATERIAL AND METHODS: Patients undergoing TULAA between July 2013 and June 2014 were retrospectively reviewed. There were two groups: A (single-incision) - one umbilical trocar for a telescope with inbuilt working channel; and B (2-trocar) - one umbilical trocar for a 'standard' telescope plus a supra-pubic trocar for instruments.
RESULTS: One-hundred and eighty-nine patients (112 males, age: 12[2-17] years) underwent TULAA; 32(17%) presented with perforated appendicitis. Group A encompassed 157 and group B 32 patients; age, gender, proportion of perforated appendicitis, and follow-up were similar. Operative time was 46 [21-145] min in group A, and 54.5[30-111] in group B (A vs B, p = 0.087). Length of hospital stay was 2 [1;22] days in group B, and 2 [0;24] in group A (A vs B, p = 0.136). The prevalence of post-operative complications was similar: 11 (7%) cases in group A and 2 (6.3%) intra-abdominal abscesses in group B. Using disposable trocars, the more expensive starting point of single-incision technique may be reversed after 27 procedures.
CONCLUSION: Single-incision and 2-trocar TULAA are effective techniques with low complication rates and similar outcomes. Despite being technically more demanding, single incision may be advantageous because there are no visible scars, and potentially cheaper in hospitals where disposable trocars are used.
