Abstract
PURPOSE: To evaluate the outcome of laparoendoscopic single-site (LESS-A) through one transumbilical port vs. 3-port laparoscopic (3TA) appendectomy in children.
METHODS: We reviewed the records of 309 children (65 LESS-A, 244 3TA) operated on between 2008 and 2012. One hundered forty-nine patients had acute catarrhalis (CA), 133 phlegmonous (PLA), and 27 perforated appendicitis (PA). We compared the duration of operation (DO) the incidence of abdominal abscesses (AA)and wound infections (WI), as well as the degree of appendiceal inflammation (DI) among surgeons with and without board certification.
RESULTS: For all DI, LESS-A resulted in a shorter DO than 3TA (CA 57.9 ± 22.8 vs. 68.5 ± 23.2, P = 0.014; PLA 51.5 ± 16.5 vs. 68.4 ± 33.0, P = 0.006; PA 66.0 ± 29.0 vs. 97.3 ± 41.8, P = 0.039).
LESS-A was not used for less complicated cases when compared to 3TA (CA 50.8% vs. 47.5%; PLA 33.8% vs. 45.5%; PA 15.4% vs. 7.0%; CA vs. PLA, P = 0.292; CA vs. PA, P = 0.142; PLA vs. PA, P = 0.031). Surgeons without board certification were assigned to a similar percentage to perform both techniques for any DI (CA 30.3% vs. 37.1%, P = 0.541; PLA 31.8% vs. 40.5%, P= 0.484; PA 40% vs. 35.3%, P = 1.0).
We found no significant differences concerning AA (1.5% vs. 1.2%, P = 1.0) and WI (3.1% vs. 1.6%, P = 0.61).
CONCLUSIONS: LESS-A can be done by surgeons with and without board certification for all DI, with shorter DO and similar complication rates as compared to 3TA.
