BACKGROUND: This study aimed to compare preperitoneal ventral mesh patch with barbed suture in ventral hernia repair, evaluating recurrence rates and complications, and to assess the safety of preperitoneal patch placement.

METHODS: In this randomized clinical trial, adult patients undergoing ventral hernia repair at Karlskoga Hospital between 2020 and 2023 were randomized 1 : 1 to either a ventral mesh patch repair group or a non-absorbable barbed suture repair group, blinded to patients and outcome assessors. The primary outcome was recurrence detected at clinical examination and CT verification 1 year after surgery. Pain (measured on a visual analogue scale and using the Ventral Hernia Pain Questionnaire), nausea, and surgical site events (including wound infection, haematoma and seroma) were assessed 4 h, 1 week, 1 month, and 4 years after operation.

RESULTS: Of 256 eligible patients, 209 were screened, and 205 were randomized to ventral mesh patch repair (103) or barbed suture repair (102). The hernia recurrence rate at 1 year was lower in the ventral patch repair group (1.9 versus 5.9%), although this was not statistically significant (P = 0.14). The surgical site infection rate at 1 month was significantly lower in the ventral patch group (0.9 versus 6.9%; P = 0.02). At 1 month, the ventral patch repair group had higher 'pain right now' scores on the Ventral Hernia Pain Questionnaire (P = 0.02), although this difference had disappeared by 1 year.

CONCLUSION: Preperitoneal ventral hernia patch repair is a safe and effective technique with a recurrence rate not statistically significant from that after barbed suture repair. Although postoperative pain scores at 1 month were higher after ventral patch repair, this difference had disappeared by 1 year.
