Topic overview
Abstract
Background
This study compared perioperative outcomes between laparoscopic surgery (LS) and open surgery (OS) for pediatric inguinal hernia repair, using a national inpatient database.
Methods
Using the Diagnosis Procedure Combination database in Japan, we compared duration of anesthesia, postoperative complications, recurrence, and metachronous hernia (MH) between LS and OS for children undergoing inguinal hernia repair from July 2010 to March 2016. We used multivariable logistic regression analysis for postoperative complications and Cox regression analysis for recurrence.
Results
For 75,486 eligible patients (LS 20,186 vs. OS 55,300), the median follow-up was 815 (381–1350) days in LS and 1106 (576–1603) days in OS. The duration of anesthesia was significantly longer in LS than in OS for unilateral surgery (80 vs. 70min, p
