To analyze the clinical effect of modified medical adhesive pseudohernia sac technique in preventing seroma after totally extraperitoneal hernia repair (TEP) for direct hernia.

From February 2019 to March 2021, 93 patients with direct inguinal hernia who were admitted to Department of Hepatobiliary Hernia and Abdominal Wall Surgery, Xi'an Central Hospital were randomly divided into two groups by random number table method. Among them, 47 patients in experimental group were treated with modified medical adhesive pseudohernia sac technology, and 46 patients in the control group were sutured with 3-0 absorbable suture continuously. Both groups were followed up to 12 months after operation. The operation time, intraoperative bleeding, time out of bed, average hospitalization time, hospitalization cost, operation area infection, incidence of seroma, early pain and chronic pain were observed in 2 groups.

There was no significant difference between the experimental group and the control group in terms of intraoperative bleeding, hospital stay, and hospital costs (P>0.05); The operation time of the experimental group was significantly shorter than that of the control group (P<0.05). The time of getting out of bed in experimental group was significantly longer than that in control group (P<0.05). There was no postoperative infection in the operation area in the experimental group and the control group. There were 4 patients in the control group who had chronic pain, and no patient in the experimental group who had chronic pain, the difference was statistically significant (P<0.05). The incidence of seroma in the experimental group was 4.25% (2/47), which was significantly lower than that in the control group 23.91% (11/46; P<0.05). The incidence of early postoperative pain in the groin area in the experimental group was 2.13% (1/47), which was significantly lower than that in the control group 13.04% (6/46; P<0.05).

The modified medical adhesive pseudohernia sac technique to prevent seroma after laparoscopic TEP hernia repair is simple, safe and reliable.
