[Laparoscopic high ligation of hernia sac and median umbilical fold covering internal ring in treating pediatric indirect inguinal hernia].

OBJECTIVE
To investigate the effect and clinic practice of laparoscopic high ligation of hernia sac and median umbilicus fold covering internal ring in pediatric indirect inguinal hernia.


METHODS
Five hundred and fifty-two children with indirect inguinal hernia were randomly divided into group A (control group) and group B (combination group) according to their check-in dates (odd or even). In group A, 275 children were treated with laparoscopic high ligation of hernia sac. In group B, 277 children were treated with laparoscopic high ligation of hernia sac and suturing the median umbilical fold to internal ring.


RESULTS
The operation was successfully performed in all 552 patients. The operating time in group A and B were (12.3 +/- 5.5) min and (20.6 +/- 4.2) min (P<0.05) respectively; and the hospital stay were (2.2 +/- 1.5) d and (2.4 +/- 1.3) d (P>0.05); the day of restoring normal active were (1.2 +/- 0.5) d and (1.3 +/- 0.6) d (P>0.05); the recurrence rate were 2.2% (6/275) and 0 (0/277) (P<0.05). No complications, such as abdominal cavity infection and scrotum hematoma occurred during the follow-up of 22 months to 55 months.


CONCLUSIONS
Laparoscopic high ligation of hernia sac and median umbilical fold covering internal ring is safe and effective in treating indirect inguinal hernia of the children.
