Abstract

Background: Techniques of retromuscular repair of ventral hernias aim at avoiding complications linked to intraperitoneal patch. Aim of the study was to evaluate results of the VTEP technique.

Methods: On 187 patients who underwent a VTEP, evaluation was carried out on 128 patients with a minimum follow-up of 1 year. The surgical technique consisted of creating connection between both retro-rectus spaces, by division of the medial edges of the posterior sheath and deploying the patch in the retromuscular patch without fixation. The posterior sheath was repaired in 16 cases. The patients were sent a questionnaire and invitation to have physical examination by the surgeon.

Results: The mean hernia and patch size were 9 (1-50) and 225 (50-500) cm2, respectively. The mean follow-up was 21.2 (12-35) months; 120 (93.7%) patients were evaluated, 21 by physical examination, 41 by questionnaire, 58 by telephone and 8 (6.3%) were lost to follow-up. Hundred (83%) patients felt no pain at rest, and 88 (73%) during effort. Among patients who felt some degree of pain, the mean VAS value was 2 (1-4) at rest and 2.6 (1-7) during effort. Two recurrences occurred, 3 patients were worried about a persisting diastasis bulging at the upper border of the patch and 8 patients in which the posterior sheath was not repaired complained they felt that their upper abdomen was somewhat distended or swollen.

Conclusion: The VTEP procedure provides a low level of chronic pain but can entail some drawbacks, such as the swollen abdomen, which can be attributed to the absence of repair of the posterior sheath. It may be that restoring or preserving structural integrity of the abdominal belt formed by the posterior sheath constitutes a key point in retromuscular techniques.
