To investigate the efficacy of laparoscopic internal ring closure combined with medial umbilical ligament coverage in the treatment of children with recurrent indirect inguinal hernia.

46 children with recurrent indirect inguinal hernia who were admitted in Maternal and Child Health Care Hospital of Tongzhou District, Beijing were selected, they were divided into the control group (23 cases) and the observation group (23 cases) according to the random number table method. The control group was treated with laparoscopic internal ring closure, while the observation group was treated with laparoscopic internal ring closure combined with medial umbilical ligament coverage. The operation related indexes, pain degree after operation, complications and recurrence during 1 year follow-up were observed and compared between the two groups.

In the observation group, 3 cases with medial umbilicus ligament atrophy could not be pulled to the internal inguinal canal ring, and they were treated with laparoscopic internal ring closure. There was no significant difference in the operation time, intraoperative blood loss, walking time, hospitalization time, pain in the operation area, and postoperative abdominal pain between the two groups (P>0.05). One year after operation, the incidence of complications and recurrence rate in the observation group were lower than those in the control group, but the difference was not statistically significant (P>0.05).

Compared with single laparoscopic internal ring closure, laparoscopic internal ring closure combined with medial umbilical ligament coverage did not prolong the operation time or increase the intraoperative blood loss. The incidence of complications and recurrence rate 1 year after operation tended to be lower than those of the control group.
