Characteristics and Treatments for Pediatric Ordinary and Incarcerated Inguinal Hernia Based on Gender: 12-Year Experiences from a Single Center

Abstract

Background: Congenital primary inguinal hernia is a common condition among children. Although much literature regarding inguinal hernia is available, large scale analysis are few, and rarely do they expand on gender difference or incarcerated hernias.Methods: Patients with unilateral or bilateral inguinal hernia who were admitted to our hospital and received open inguinal hernia repair (OIHR) or laparoscopic inguinal hernia repair (LIHR) under general anesthesia were included. LIHR was performed using single-site laparoscopic percutaneous extraperitoneal closure (SLPEC). Medical records were retrospectively collected and analyzed.Results: A total of 12190 patients were included in this study. The ratio of male to female was 4.8:1. There was a total of 10646 unilateral hernias (87.3%) and 1544 bilateral hernias (12.7%), with a corresponding ratio of 6.9:1. 12444 hernia repair surgeries, 11083 (89.1%) OIHR and 1361 (10.9%) LIHR, were held.OIHR had a shorter operative time than LIHR for all unilateral and female bilateral repair, unlike for bilateral male repair. There was no difference between OIHR and LIHR for ipsilateral recurrent hernia in males. There was a difference between OIHR and LIHR for metachronous contralateral hernia.Incarcerated inguinal hernia was associated with longer operative time, hospital stay and higher hospital costs. Females and patients under 1 year were more likely to present with incarcerated hernia.Conclusions: OIHR should be considered for male patients, especially for unilateral and complete inguinal hernia. LIHR is highly recommended for female patients. For incarcerated hernia, attention should be paid to patients under 1 year old, as they can be 60 times more susceptible, and females. Surgeons should also be aware of ovary hernias in females.
