Totally extraperitoneal (TEP) endoscopic inguinal hernia repair with TAP (transversus abdominis plane) block as a day-case: A prospective cohort study

Abstract

Totally extraperitoneal (TEP) endoscopic inguinal hernia repair is indicated for recurrent and bilateral inguinal hernias and traditionally is performed under general anesthesia. However, interventions that minimize pain and reduce opioid consumption have certain advantages for patients by avoiding side effects such as nausea and vomiting. The transversus abdominis plane (TAP) block has been used to minimize pain in a diverse range of surgical procedures but its safety on patients undergoing TEP repair has yet to be investigated. To assess the results of outpatient TEP repair with TAP block without curare. Consecutive patients undergoing elective TEP procedure were prospectively enrolled. Patients in two institutes received a similar anesthetic, surgical, and analgesic treatment protocol. Fifty consecutive day-case patients were included in this series. The TEP repair was successful in 49 patients and there was one conversion to transabdominal pre-peritoneal (TAPP) endoscopic inguinal hernia repair. The mean duration of surgery was 20min for unilateral hernia and 40min for bilateral hernia. These preliminary results suggest that day-case endoscopic hernia repair (TEP) with TAP block without curare is effective, safe, reproducible and can be proposed in all patients.
