Our Experiences and Comparison of Total Extraperitoneal (TEP) And Transabdominal Preperitoneal (TAPP) Techniques in Laparoscopic Inguinal Herni Repair

Aim: In this study, it was aimed to compare the results of Total Extraperitoneal (TEP) and Transabdominal Preperıtoneal (TAPP) surgical methods in laparoscopic inguinal hernia repair. Methods: The data of 317 patients who underwent laparoscopic inguinal hernia repair surgery with the diagnosis of inguinal hernia between October 2016 and January 2021 in the General Surgery Clinic of SBU Sultan 2. Abdulhamid Han Training and Research Hospital were evaluated retrospectively. The wound dehiscence, swelling in the incision or scrotum, recurrence, and the postoperative day of returning to work were questioned. The results of TAPP and TEP methods were compared statistically. Results: In our study, the mean age of 317 patients who underwent surgery with TEP and TAPP methods was 50.5, and 27 of them were female and 290 were male. Postoperative recurrence was observed in 21 (6.6%) patients, wound dehiscence in 11 (3.4%) patients, swelling at the incision in 44 (13%) patients, and scrotal swelling in 30 (9.4%) patients. It was determined that the patients who underwent the TEP procedure returned to work after an average of 5.09 (1-30) days, and the patients who underwent the TAPP procedure after an average of 4.04 (1-14) days. When the two groups were compared, there was no significant difference between the groups in terms of return to work day in the postoperative period (p= 0.707), recurrence in the postoperative period (p=0.493), swelling at the incision (p=0.479), scrotal swelling (p=0.356), and wound dehiscence (p=0.245). Conclusions: There are two methods commonly used today in the repair of inguinal hernia by laparoscopic method. TEP method is performed in the preperitoneal area and TAPP method is performed in the intraperitoneal area. In this study, the results of TEP and TAPP methods were compared and it was found that there was no statistically significant difference between the two procedures in terms of postoperative recurrence, time to return to work and postoperative complications.
