importance of mesh overlap on recurrence after open umbilical hernia repair has been poorly studied.
a retrospective cohort study was performed with patients who underwent open umbilical hernia repair with bilayer prosthesis between 2004 and 2015.
1538 patients were included. Fifty patients (3.3%) had a mesh overlap lower than 1 cm. After a mean follow-up of 4.1 years 53 patients (3.5%) developed a recurrence. Recurrence was associated with a mesh overlap smaller than 1 cm (10.2% vs. 3.3%, p = 0.010, OR = 3.3). In the logistic regression model an overlap smaller than 1 cm was not statistically associated with recurrence (OR = 2.5, p = 0.123). Female gender, postoperative complications and prosthesis size were associated with hernia recurrence.
mesh overlap seems to be an important factor for hernia recurrence. A mesh overlap of at least 1 cm should be used until more studies are performed about this issue.
网片重叠在开放式脐疝修补术后复发中的重要性尚未得到充分研究。
对 2004 年至 2015 年间接受双层补片开放式脐疝修补术的患者进行回顾性队列研究。
共纳入 1538 例患者。50 例（3.3%）的网片重叠小于 1cm。平均随访 4.1 年后，53 例（3.5%）患者复发。复发与网片重叠小于 1cm 有关（10.2% vs. 3.3%，p=0.010，OR=3.3）。在逻辑回归模型中，网片重叠小于 1cm 与复发无统计学相关性（OR=2.5，p=0.123）。女性、术后并发症和补片大小与疝复发有关。
网片重叠似乎是疝复发的一个重要因素。在更多关于这个问题的研究完成之前，应使用至少 1cm 的网片重叠。
