To explore the short-term clinical feasibility of laparoscopic trans- abdominal preperitoneal hernia repair (TAPP) combined with laparoscopic inguinal canal posterior wall reconstruction based on the Bassini principle (transabdominal preperitoneal Bassini, TAPB) in the treatment of inguinal hernias at high risk of recurrence.

A retrospective analysis was conducted on the clinical data of 20 patients with inguinal hernias at high risk of recurrence who were admitted to the Department of General Surgery, the Second People's Hospital of Futian District, Shenzhen, from September 2025 to January 2026. All patients underwent TAPP combined with TAPB. Synthetic mesh or biological mesh was selected individually according to patients' age, hernia classification, characteristics of abdominal wall defect, and clinical needs. Transversus abdominis plane block was performed intraoperatively in all patients, and standardized analgesia was administered postoperatively. The operation time, blood loss, visual analogue scale (VAS) scores, hospital stay, perioperative complications, and short-term hernia recurrence rate were uniformly observed and recorded.

All 20 patients completed the surgery successfully without conversion to open surgery. The operation time was (133±49) minutes, intraoperative blood loss was (2±1) ml, and postoperative hospital stay was (4±2) days. The VAS scores on the day of surgery and the first postoperative day were both (2±1) points, indicating a mild degree of pain. One case of inferior epigastric vein injury occurred intraoperatively, which was treated with Hemolock clipping for hemostasis and had a good prognosis. No severe perioperative complications were observed. All patients completed 3-9 months of follow-up, and no hernia recurrence was observed during the follow-up period.

TAPP combined with laparoscopic inguinal canal posterior wall reconstruction based on the Bassini principle is safe and feasible in the short term, which can provide a minimally invasive treatment option for clinical practice. The long-term efficacy and safety need to be further verified by prospective studies with larger sample sizes and longer follow-up periods.
