CTEP Versus LESS Totally Extraperitoneal Hernioplasty

BACKGROUND AND OBJECTIVES: The authors sought to assess and compare the surgical outcomes of laparoendoscopic single-port surgery (LESS) for totally extraperitoneal (LESS-TEP) hernioplasty and conventional totally extraperitoneal (CTEP) hernioplasty. METHODS: From March 2015 through May 2018, a retrospective analysis of postoperative outcomes was conducted that included 81 cases of LESS-TEP and 88 cases of CTEP hernioplasty patients. For postoperative indicator comparisons, a visual-analog pain scale and 5-level cosmesis evaluation sheet were applied. In addition, complications on postoperative outcomes following inguinal hernia repair surgery are discussed based on our analysis and surgical experience. RESULTS: All operations were successfully performed at different hospitals. Compared with the CTEP group, the operative time in the LESS-TEP group increased significantly (P < .05). However, the cosmetic outcome in the LESS-TEP group was rated higher than that in the CTEP group (P < .05). There was no significant difference between the 2 groups in hospitalization time, the incidence of complications, postoperative pain levels, or medical costs (P > .05). CONCLUSION: LESS-TEP is as feasible and safe as CTEP. The use of LESS-TEP successfully improved the cosmetic outcomes of inguinal hernia repair surgery with smaller and fewer scars for patients. As a new surgical treatment approach for inguinal hernias, the LESS-TEP technique is still not a necessary or efficacious surgical alternative strategy for CTEP, especially for surgeons who are less experienced in the technique.
