The investigators plan a retrospective, single-center outcome analysis of laparoscopic hernia repair in children operated between March 2nd, 2010, and March 1st, 2014. Data analysis will be based on a review of hospital records and a questionnaire answered by families. Patient demographics (age, gender), affected side, type and duration of laparoscopic intervention, and outcome parameters (hernia recurrence, post-operative complications, eg. infections, length and type of postoperative pain medication, and length of the postoperative hospital stay) will be analysed.
