Observational Study
Single centre observational study to evaluate the safety and efficacy of the Proceed™ Ventral Patch to repair small ventral hernias.
There is evidence that mesh repair for primary umbilical hernias results in less recurrences and similar wound complication rates compared to tissue repair. In recent years, several mesh devices for the repair of small ventral hernias have been developed, but some reports have been published on serious complications and adverse effects encountered with those mesh devices. ⋯ Intensive clinical follow-up yields a high percentage (12.0 %) of clinically proven, but often asymptomatic recurrences after repair of small ventral hernias with the PVP™. Reoperation rate for recurrence was 5.1 %. Hernia defect size is a significant risk factor for recurrence. Therefore, we recommend using the PVP™ only for primary ventral hernias smaller than 2 cm. For larger or incisional hernias other techniques allowing the use of larger meshes is advocated.

Ventral hernias are common and repair with mesh has been shown to reduce recurrence. However, synthetic mesh is associated with a risk of infection. Biologic mesh is an alternative that may be less susceptible to infection. Typically, the sublay position is preferred for mesh placement but this technique takes longer and has not been shown to have a lower recurrence rate than an onlay mesh. The aim of this study was to evaluate the outcome of complex ventral hernia repair using a porcine non-cross-linked biologic mesh onlay. ⋯ Porcine non-cross-linked biologic mesh overlay has excellent short-term results in patients at increased risk for mesh infection. No patient required mesh removal, and there have been no recurrent hernias in patients with primary fascial closure. Biologic bridging is not effective for long-term abdominal wall reconstruction.

Randomized Controlled Trial
Post-operative benefits of Tisseel(®)/Tissucol (®) for mesh fixation in patients undergoing Lichtenstein inguinal hernia repair: secondary results from the TIMELI trial.
The Tisseel/Tissucol for mesh fixation in Lichtenstein hernia repair (TIMELI) study showed that mesh fixation with human fibrin sealant during inguinal hernia repair significantly reduced moderate-severe complications of pain 12 months post-operatively compared with sutures. Further analyses may assist surgeons by investigating predictors of post-surgical complications and identifying patients that may benefit from Tisseel/Tissucol intervention. ⋯ Pre-operative discomfort may be an important predictor of post-operative pain, numbness and discomfort. Tisseel/Tissucol may improve long-term morbidity over conventional sutures in these patients.
