Development of scar-less laparoscopic hernia repair (TAPP-252) facilitated by new 2mm instruments

Introduction: To minimize the invasiveness of laparoscopic transabdominal preperitoneal hernia repair (TAPP) for the treatment of adult inguinal hernia, we developed a new operative technique with the use of only one 5?mm port and two 2?mm punctures (TAPP-252).

Material and methods: To facilitate TAPP-252, we developed seven kinds of new 2?mm instruments, including grasping forceps, hook shaped electrode, mesh pusher, needle driver, scissors, laparoscope and port.

Results: TAPP-252 was stably performed in 35 patients with minimal abdominal wall destruction and excellent cosmetic result without any recurrence or morbidity.

Conclusions: The newly developed 2?mm devices showed sufficient performance and durability in TAPP-252. Further investigation is necessary to assess durability and long-term outcomes.
