To investigate the efficacy of truss compression therapy in reducing the incidence of postoperative seroma in patients with indirect inguinal hernia undergoing laparoscopic transabdominal preperitoneal (TAPP) repair.

From May 2021 to May 2022, 50 adult male patients with indirect inguinal hernia who underwent TAPP at the Tongxiang First People's Hospital were selected and randomly divided into an experimental group and a control group. Both groups received the same TAPP procedure. In the experimental group, a truss was applied to compress the inguinal region for one week postoperatively; in the control group, routine sandbag compression was applied for 12 hours after surgery. The two groups were compared in terms of baseline characteristics, size of the hernia ring defect, whether the hernia sac was completely dissected, operative time, intraoperative blood loss, postoperative hospital stay, incidence and classification of postoperative seroma, and hernia recurrence rate.

There were no statistically significant differences between the two groups in baseline characteristics, intraoperative parameters, or length of postoperative hospital stay (all P>0.05). The incidence of postoperative seroma was 8% in the experimental group, with no cases of type III seroma; in contrast, the control group had a 32% incidence of postoperative seroma, including a 16% incidence of type III seroma, and these differences were statistically significant (P<0.05). Four cases of seroma in the control group were cured after aspiration and drainage. No hernia recurrence was observed in either group during follow-up.

For patients with indirect inguinal hernia undergoing TAPP, postoperative truss compression can effectively reduce the incidence of seroma, with good safety and definite efficacy. It has achieved satisfactory short-term results in clinical practice and shows promising prospects for clinical application.
