Comparison of Clinical Outcomes of Laparoscopic Totally Extraperitoneal (TEP) and Transabdominal Preperitoneal (TAPP) Techniques in Bilateral Inguinal Hernia Repair: A Retrospective Study.

objectiveThis study compared the clinical outcomes of two commonly used laparoscopic techniques, transabdominal preperitoneal (TAPP) and totally extraperitoneal (TEP) repair, in the treatment of bilateral inguinal hernias. MATERIALS AND

methodsThis retrospective cohort study included 250 patients who underwent laparoscopic bilateral inguinal hernia repair using either the TEP or TAPP technique between May 2009 and May 2024. The patients were divided into two groups: 50 patients in the TEP group and 200 in the TAPP group. Data were collected from patient records, including demographics, type of hernia, surgical details, intraoperative and postoperative complications, conversion rates, and early hernia recurrence. Statistical analysis was performed to compare outcomes between the two groups.

resultsAmong the 250 patients included in the study, the mean age was 51.62 ± 8.79 years, and 94% (n=235) were male. The mean operative time was significantly longer in the TEP group (93.2 ± 13.0 minutes) than in the TAPP group (57.95 ± 7.5 minutes) (

conclusionThe findings suggest that, while both TEP and TAPP effectively repair bilateral inguinal hernia, TAPP is associated with shorter operative times, shorter hospital stays, and fewer postoperative complications. However, the TAPP technique also presented notable intraoperative risks, including arterial and bowel injury. The choice between TEP and TAPP should be based on the surgeon's experience, patient characteristics, and the specific clinical context.
