SYSTEMIZATION OF LAPAROSCOPIC INGUINAL HERNIA REPAIR (TAPP) BASED ON A NEW ANATOMICAL CONCEPT: INVERTED Y AND FIVE TRIANGLES

BACKGROUND: Laparoscopic inguinal hernia repair has been shown to be superior than open repairs with faster return to daily activities and decrease in the occurrence of chronic pain. However, higher direct costs and mandatory use of general anesthesia are arguments against their use. In addition, increased complexity of surgery resulting from an anatomy that is unusual to general surgeons prevents the widespread adoption of laparoscopic approach. AIM: To propose a technical systematization for transabdominal laparoscopic repair (TAPP) of inguinal hernias based on anatomical concepts. METHOD: To offer a systematization of TAPP repair based on well defined anatomic landmarks, describing the concept of “inverted Y”, identification of five triangles and three zones of dissection, to achieve the “critical view of safety” for laparoscopic inguinal hernia repair. RESULTS: Since this standardization was developed five years ago, many surgeons were trained following these precepts. Reproducibility is high, as far as, it´s rate of adoption among surgeons. CONCLUSION: The concept of the “inverted Y”, “Five triangles” and the dissection based in “Three Zones” establish an effective and reproducible standardization of the TAPP technique.
