To investigate the effect of peritoneal drainage in laparoscopic transabdominal preperitoneal hernia repair for postoperative hematoma and seroma.

A total of 90 patients with unilateral inguinal hernia admitted to Suzhou hospital of integrated traditional Chinese and Western medicine from June 2016 to May 2018 were selected and randomly divided into experimental group and control group. Both groups underwent TAPP surgery. Preperitoneal drainage tube was placed in the experimental group, while no drainage tube was placed in the control group. The general data, operative related data and follow-up data of the two groups were collected for statistical analysis, and the incidence of postoperative hematoma and seroma was compared between the two groups.

Surgery and follow-up were completed in all patients, and the follow-up rate was 100%. There were no statistically significant differences between the two groups in general data, hernia location, hernia type, operation time, hospitalization cost, and postoperative hospitalization time (P>0.05). There was no statistically significant difference between the two groups in the incidence of postoperative fever and acute pain (P>0.05). The incidence of postoperative hematoma in the experimental group was significantly lower than that in the control group (P<0.05), and the incidence of postoperative seroma in the experimental group was significantly lower than that in the control group at 1 month and 3 months after surgery (P<0.05), with statistically significant differences. One case of recurrence was observed in both groups during 1-year follow-up, and the difference was not statistically significant. There was no case of infection in both groups during the follow-up period.

During laparoscopic transabdominal preperitoneal repair, the placement of a preperitoneal drainage tube can effectively reduce the incidence of postoperative hematoma and seroma without increasing the risk of infection and recurrence.
