Observational studies have reported conflicting results with primary fascial closure (PFC) versus bridged repair during laparoscopic ventral hernia repair (LVHR).
The aim of the study was to determine whether when evaluated in a randomized controlled trial (RCT), PFC compared to bridged repair would improve patient quality of life (QoL).
In this blinded, multicenter RCT, patients scheduled for elective LVHR (hernia defects 3 to 10 cm on computed tomography scan) were randomized to PFC versus bridged repair. Primary outcome was change in QoL after LVHR using a validated, hernia-specific survey (1 = poor QoL and 100 = perfect QoL) that measures pain, function, cosmesis, and satisfaction. Secondary outcomes were postoperative surgical site occurrences (including hematoma, seroma, surgical site infection, and wound dehiscence), abdominal eventration, and hernia recurrence. The trial was powered to detect a difference in change in QoL of 7 points between the study groups. Outcomes were compared with Mann-Whitney U test or chi-square.
A total of 129 patients underwent LVHR and 107 (83%) completed follow-up at 2 years. Patients from both groups were similar at baseline. On median follow-up of 24 months (range: 9-42), patients treated with LVHR-PFC had on average a 12-point higher improvement in QoL compared to bridged repair (improvement in QoL, 41.3 ± 31.5 vs 29.7 ± 28.7, P value = 0.047). There were no differences in surgical site occurrence, eventration, or hernia recurrence between groups.
Among patients undergoing elective LVHR, the fascial defect should be closed. This is the first RCT demonstrating that PFC with LVHR significantly improves patient QoL.
This trial was registered with clinicaltrials.gov (NCT02363790).
观察性研究报告腹腔镜腹疝修补术(LVHR)中,原发性筋膜闭合(PFC)与桥接修复的结果存在矛盾。
本研究旨在确定在随机对照试验(RCT)中,与桥接修复相比,PFC 是否会改善患者的生活质量(QoL)。
在这项盲法、多中心 RCT 中,计划接受择期 LVHR(CT 扫描显示疝缺损为 3 至 10cm)的患者被随机分配至 PFC 组或桥接修复组。主要结局是使用经过验证的疝特异性调查(1=生活质量差,100=生活质量完美)评估 LVHR 后 QoL 的变化,该调查衡量疼痛、功能、美容和满意度。次要结局是术后手术部位发生的情况(包括血肿、血清肿、手术部位感染和伤口裂开)、腹外疝和疝复发。该试验的功率足以检测两组间 QoL 变化差异 7 分。结果通过 Mann-Whitney U 检验或卡方检验进行比较。
共 129 例患者接受了 LVHR,其中 107 例(83%)在 2 年时完成了随访。两组患者在基线时相似。在中位数为 24 个月(范围:9-42)的随访中,与桥接修复相比,接受 LVHR-PFC 治疗的患者的 QoL 平均改善了 12 分(QoL 改善,41.3±31.5 vs 29.7±28.7,P 值=0.047)。两组之间在手术部位发生、腹外疝或疝复发方面没有差异。
在接受择期 LVHR 的患者中,筋膜缺损应闭合。这是第一项 RCT 证明,PFC 联合 LVHR 显著改善了患者的 QoL。
该试验在 clinicaltrials.gov(NCT02363790)注册。
