Die laparoskopische Herniorrhaphie des Leistenbruches im Kindesalter - Erfahrungen in einem Krankenhaus der Grund- und Regelversorgung

AIM: Children undergoing laparoscopic herniorrhaphy may benefit from a minimally invasive access and the possible exploration of the contralateral groin. In this prospective feasibility study, the experiences and results after introduction of this method in a tertiary referral medical center are reported. METHODS: 50 laparoscopic herniorrhaphies were performed in 44 children (32 boys and 12 girls, range: 17 months-11 years) with open inner inguinal rings between January 2001 and March 2007. In 6 children (13.6 %) an additional contralateral open inner inguinal ring was detected. Laparoscopic access was obtained with a 5-mm laparoscope which was inserted transumbilically and two 2-mm needle holders were inserted through the inferolateral abdominal wall. The open inner inguinal rings were closed in 8 children using a resorbable Z-suture and in 36 children using a monofilamentous non-absorbable suture. Follow-up examinations included records of intra- and postoperative complications, recurrence rate and economic aspects. RESULTS: No intra- or perioperative complications occurred. Median operation time was 19 minutes. 43 / 44 operations were carried on an outpatient basis. Average material costs were about 20 Euro without any difference from the open access. During 36 months the follow-up rate was 91 %. Two children who had previously received an absorbable suture suffered from a recurring groin hernia within the first 6 months. CONCLUSION: Laparoscopic herniorrhaphy in children represents a safe and effective surgical method that can be recommended for tertiary referral medical centers with training facilities and experience in minimally invasive surgery.
