Laparoscopic inguinal hernia repair in premature babies weighing 3 kg or less.

PURPOSE: This retrospective study aims to evaluate the feasibility, safety and complication rate of laparoscopic inguinal hernia repair for small babies weighing 3 kg or less. METHODS: A retrospective analysis was performed on the surgical charts of 67 infants (47 boys and 20 girls) weighing 3 kg or less who underwent laparoscopic hernia repair in a 3-year period. A regular 5-mm scope was used for visualization, and 2 or 3-mm instruments were used for the closure of the inner inguinal ring using 3/0 non-absorbable suture. The median weight at surgery was 2,600 g (range 1,450-3,000 g). All except three were premature. RESULTS: Of the 67 infants, 15 (22.3 %) presented with an irreducible hernia. In three cases of irreducible hernias, we also performed a transumbilical appendectomy at the end of the hernia repair. Minor problems related with anesthesia were noted in four cases. Hernia recurrence was observed in three patients (4.4 %). No cases of testicular atrophy occurred. In 10 boys, we observed 12 cases of high testes, only 4 testes requiring subsequent orchiopexy. CONCLUSIONS: Laparoscopic inguinal hernia repair for babies weighing 3 kg or less is feasible, safe and perhaps even less technically demanding than open inguinal herniotomy.
