Background: Inguinal hernia repair is one of the most common pediatric surgeries that can be approached with an open or laparoscopic approach. The aim of this study was to describe outcomes and complications of flip flap inguinal hernia repair analyzing our experience in the last 5 years.
Methods: Between 2015 and 2020, 280 children admitted at our department with inguinal hernia requiring surgery were included. Secondary aim was to investigate how confidence of surgeons regarding VLS approach increase during time and how this particular technique represents a primary procedure useful to increase surgeons' skills in performing laparoscopic sutures.
Results: One hundred sixty children (57%) underwent open approach, whereas 120 (43%) laparoscopic ligations of hernia. For each group, clinical and surgical data were recorded. We focused on comparing postoperative complications: the most frequent complication was hydrocele (N.=4, 1.4%). Reported postoperative complication were not statistically different between two groups (open N.=3, 1.8% vs. laparoscopy N.=1, 0.8%). No other postoperative complications were documented in our cohort for both groups. In laparoscopic group we registered 3 cases of ipsilateral recurrence (1.6%) and no cases of metachronous hernia. The choice of laparoscopic approach significantly increased from 22% in 2015 to 74% in 2020 (P<0.05) as well as the percentage of male underwent to laparoscopic procedure (38% in 2015 to 74% in 2020, P<0.05).
Conclusions: It is known that the rate of complication or recurrence is similar for open or minimally invasive inguinal hernia repair. Laparoscopy offers advantages such as the possibility of visualizing contralateral internal inguinal ring, reducing the incidence of metachronous inguinal hernia. Moreover, taking confidence with a minimally invasive technique such Flip Flap hernioplasty by performing it repeatedly over time, leads to an improvement of surgeons' skills also in performing laparoscopic sutures, that can be helpful for other complex or tricky procedures.
