To investigate and compare the effects between negative pressure suction under laparoscopy and hernia needle on injuries in the treatment of inguinal hernia in children.

164 children with inguinal hernia were selected from October 2016 to February 2018 in general surgery department of Tanghe County People's hospital. According to the different surgical methods, they were divided into the negative pressure suction group (82 cases) and the hernia needle group (82 cases). The negative pressure suction group was treated by laparoscopic negative pressure suction percutaneous extraperitoneal ligation method and the hernia needle group was treated with laparoscopic double hook hernia needle percutaneous extraperitoneal ligation. The clinical indicators, postoperative indicators, complications and recurrence rate of hernia of the two groups were observed and compared.

The operation time and diameter of the needle in the negative pressure suction group were significantly lower than those in the hernia needle group (P<0.05), but there was no significant difference in the incidence of side effects between the two groups (P>0.05). There was no significant difference in hospitalization time between the two groups (P>0.05), but the postoperative pain duration and hospitalization cost were lower in the negative pressure suction group than those in the hernia needle group (P<0.05). There was no significant difference in the incidence of scrotal edema, incision infection, and hernia recurrence between the two groups (P>0.05).

Compared with percutaneous extraperitoneal ligation with percutaneous hernia needle under laparoscope, percutaneous extraperitoneal ligation with negative pressure suction under laparoscope has shorter operation time, less trauma and no increase in complications. It has a wide clinical application prospect in the treatment of inguinal hernia in children and is worthy of further application in clinical practice.
