To summarize the surgical experience and techniques of laparoscopic transabdominal preperitoneal (TAPP) hernia repair and its influence on the postoperative seroma.

A retrospective analysis was conducted on the clinical data of 52 inguinal hernia patients undergoing TAPP hernia repair in Qingdao Cardiovascular Hospital and the south hospital of Qingdao University from January 2023 to November 2024. The surgical path of TAPP, anatomic landmarks, fat tissue management, layer transition, membrane dissection, mesh selection, wound management, suturing techniques for the parietal peritoneum, application of the greater omentum were described and analyzed.

All patients successfully completed the TAPP surgery. One patient was converted to open surgery. None of the patients had drainage tubes. Within 24 hours after the operation, the groin operation area was routinely pressurized with a 500 g salt bag (the salt bag was wrapped in a dry cotton towel and the swimming underwear was tightened). The patients were followed up for one month after the operation, no seroma occurred.

The surgical experience and techniques such as proper fat tissue management and clear dissection of layers can effectively avoid the seroma after TAPP. Mastering small techniques proficiently is helpful to shorten the operation time, and is beneficial to both the surgeon and the patient.
