LIECHTENSTEIN VERSUS LAPAROSCOPIC TRANSABDOMINAL PREPERITONEAL (TAPP) HERNIA REPAIR: A PROSPECTIVE COMPARATIVE STUDY...

Three surgical techniques for inguinal hernia repair are currently validated. Few studies have compared results among Lichtenstein and transabdominal preperitoneal (TAPP) laparoscopic approach obtained at an early step of the learning curve. This study aims to compare the early treatment results between the Liechtenstein technique and the laparoscopic TAPP approach to provide a basis for the surgeon's decision-making.

Patients were divided into two groups: those who underwent laparoscopic TAPP approach (114 patients), and those who underwent open Lichtenstein repair (35 patients). Data were collected from the medical records during the evolution of the immediate postoperative period and by telephone contact after hospital discharge. For the analysis of the variables, the chi-square test of independence was implemented, with a level of significance set at a p-value of 0.05.

There was a strong association between laparoscopy, less postoperative pain, and longer operative time. In addition, a preference for the technique in cases of recurrence, bilaterality, associated umbilical hernia, or obesity was noticed. In this study, the Lichtenstein technique was associated with a shorter time to return to work and was the treatment of choice for elderly patients.

TAPP laparoscopic herniorrhaphy should be the first choice in cases of bilaterality, associated umbilical hernia, obesity, and recurrence to a previous anterior repair. The surgical risk is adequate for the procedure, even at early stages of the learning curve.
