Trans-abdominal Pre-peritoneal (TAPP) Inguinal Hernia Repair with Liquid-injection and Gauze Dissection

Purpose : This report describes a novel technique for trans-abdominal pre-peritoneal (TAPP) inguinal hernia repair using liquid injection and gauze dissection. Methods : Twenty-five cases underwent TAPP inguinal hernia repair with liquid-injection and gauze dissection. Before the initial peritoneal incision, liquid injection was performed percutaneously into the pre-peritoneal space at the outside of the internal inguinal ring and the inside of the seminal duct. Especially, at the inside of the seminal duct, the liquid was injected into the space between the superficial and deep lobe of pre-peritoneal fascia. Gauze was effectively used to dissect this liquid-injected space. Results : In comparison with the cases of inguinal hernia repair without liquid-injection and gauze dissection, the cases who underwent TAPP inguinal hernia repair with liquid-injection and gauze dissection experienced shorter operation times and no complications or recurrence. Conclusions : TAPP inguinal hernia repair with liquid-injection and gauze dissection appears to be a safe and feasible procedure.
