The conclusions of the PRIMA (PRImary Mesh closure of Abdominal midline wounds) trial¹ (Aug 5, 2017, p 567) need to be taken with caution for several reasons. The rate of 18% of incisional hernia in patients receiving prophylactic sublay mesh implantation is very high compared with frequencies below 5% in many other reports.^2,3 Furthermore, most series report a lower recurrence rate after sublay than onlay mesh implantation in the repair of incisional hernia.^4,5 Therefore, the technical problems or insufficient training with the sublay group does not allow the conclusion that onlay mesh reinforcement has the potential to become the standard treatment for high-risk patients having elective midline laparotomy.

中线剖腹手术中的预防性补片。

出于几个原因，需要谨慎对待PRIMA（腹部中线伤口的初级网状闭合）试验^{1 （2017 年 8 月 5 日，第 567 页）的结论。}与许多其他报告中低于 5% 的频率相比，接受预防性 sublay 网片植入的患者切口疝的发生率为 18%。^2,3此外，大多数系列报告在切口疝的修复中，亚层后的复发率低于高嵌网植入。^4,5因此，由于子层组的技术问题或培训不足，无法得出结论，即嵌体网加固有可能成为选择性中线剖腹手术的高危患者的标准治疗方法。
