Background: Many surgeons utilize biologic mesh for elective complex ventral hernia repair (VHR; large hernias, contaminated fields, or patients with comorbid conditions). However, no randomized controlled trials (RCTs) have compared biologic and synthetic mesh. We hypothesize biologic mesh would result in fewer major complications at one-year post-operative compared with synthetic mesh.

用于复杂开放腹疝修复的合成网与生物网：一项试点随机对照试验

背景：许多外科医生利用生物网片进行选择性复杂腹疝修复（VHR；大疝、受污染的区域或有合并症的患者）。然而，没有随机对照试验 (RCT) 比较生物网片和合成网片。我们假设与合成网片相比，生物网片在术后一年内会导致更少的主要并发症。
