Efficacy of extended view totally extra peritoneal approach versus laparoscopic intraperitoneal on lay mesh plus for abdominal wall hernias: a single center preliminary retrospective study

BACKGROUND: Laparoscopic minimally invasive surgery has become the primary treatment for ventral hernias. The laparoscopic intraperitoneal on lay mesh (IPOM) plus approach for abdominal wall hernias is the most used procedure, while extended view totally extraperitoneal (e‑TEP) repair is a newer option. This study aimed to compare the effectiveness and complications of the 2 procedures for abdominal wall hernias repair. METHODS: This was a retrospective and comparative single-center study done at The Second Clinical Medical College, Jinan University Hospital (Shenzhen People’s Hospital), Shenzhen, China. The study included patients with a 2 to 6 cm abdominal wall defect who underwent hernia repair from January 2022 to December 2022. Patients’ baseline characteristics, hernia features, operative time, blood loss, postoperative pain level, and total hospitalization expenses were extracted from the medical records and compared between patients who underwent the IPOM plus and e-TEP repair. RESULTS: A total of 53 patients were included: 22 in the e-TEP group and 31 in IPOM plus group. Patient demographic characteristics were similar between the 2 groups. The operation time of the e-TEP groups was significantly longer than the IPOM plus (98.5 ± 10.7 min vs. 65.9 ± 7.3 min, P < 0.01). Postoperative pain levels (VAS; visual analog scale) (4.2 ± 0.9 vs. 6.7 ± 0.9, P < 0.01), analgesic requirements (Tramadol) (25.0 ± 37.0 mg vs. 72.6 ± 40.5 mg, P < 0.01), length of hospital stay (1.2 ± 0.5days vs. 2.2 ± 0.6days, P < 0.01), and total hospitalization expenses (19695.9 ± 1221.7CNY vs. 35286.2 ± 1196.6CNY, P < 0.01) were significantly lower in the e-TEP group. The mean intraoperative blood loss was similar between the 2 groups. No postoperative complications were observed in either group. CONCLUSION: The e-TEP approach for abdominal wall hernias appears to be better than IPOM plus with respect to postoperative pain levels(VAS: 4.2 ± 0.9 vs. 6.7 ± 0.9, P < 0.01), analgesic requirements(25.0 ± 37.0 mg vs. 72.6 ± 40.5 mg, P < 0.01), length of hospital stay(1.2 ± 0.5days vs. 2.2 ± 0.6days, P < 0.01), and hospitalization costs (19695.9 ± 1221.7CNY vs. 35286.2 ± 1196.6CNY, P < 0.01).
