Abstract

BACKGROUND

Ileocolectomy is the most common surgery performed for Crohn's disease, and postoperative complications occur frequently. There has been minimal evaluation of complications after ileocolectomy as a function of both clinical and genetic factors.

OBJECTIVE

The purpose of this study was to evaluate both genetic and clinical factors associated with complications after Crohn's ileocolectomy.

DESIGN

This was a retrospective clinical and genetic cohort study.

SETTINGS

This study was conducted at a high-volume tertiary care center.

PATIENTS

We identified 269 patients with Crohn's disease who had undergone 287 ileocolectomies at our institution between July 2008 and October 2018.

MAIN OUTCOME MEASURES

We measured the association of complications with a combination of clinical factors and 6 Crohn's-associated single nucleotide polymorphisms in NOD2 (rs2076756, rs2066844, and rs2066845), IRGM (rs4958847 and rs13361189), and ATG16L1 (rs2241880).

RESULTS

There were 86 ileocolectomies of 287 (30%) with complications requiring intervention. The single nucleotide polymorphism rs13361189 in the gene IRGM was significantly associated with complications on univariate and multivariate analysis. There were 61 patients with a variant at the rs13361189 single nucleotide polymorphism and 26 of them had complications, although only 55 of the 208 wild-type patients had complications (43% vs 26%; OR = 2.1; p = 0.02). Other significant factors associated with complication after ileocolectomy were open surgery, placement of a proximal ileostomy, and a greater perioperative decrease in hematocrit.

LIMITATIONS

This study was limited by its retrospective design and inherent selection bias.

CONCLUSIONS

In addition to clinical risk factors, the rs13361189 single nucleotide polymorphism in the IRGM gene was independently associated with complications after ileocolectomy for Crohn's disease. The use of such genetic determinants may identify patients at increased risk for surgical complications after ileocolectomy. See Video Abstract at http://links.lww.com/DCR/B124.

Otros factores significativos asociados con las complicaciones después de la ileocolectomía fueron, la cirugía abierta, la colocación de una ileostomía proximal y una mayor disminución perioperatoria del hematocrito.Este estudio estuvo limitado por su diseño retrospectivo y sesgo de selección inherente.Además de los factores de riesgo clínicos, el polimorfismo de un solo nucleótido rs13361189 en el gen IRGM se asoció independientemente con complicaciones después de la ileocolectomía, para la enfermedad de Crohn. El uso de tales determinantes genéticos puede identificar a los pacientes con mayor riesgo de complicaciones quirúrgicas, después de la ileocolectomía.

摘要

背景

回肠切除术是克罗恩病最常见的手术,术后并发症经常发生。对于回肠切除术的并发症,只有很少的评估是基于临床和遗传因素的。

目的

本研究旨在评估与克罗恩病回肠切除术后并发症相关的临床和遗传因素。

设计

这是一项回顾性的临床和遗传队列研究。

地点

本研究在一家高容量的三级护理中心进行。

患者

我们确定了 269 名患有克罗恩病的患者,他们在我们的机构接受了 287 次回肠切除术,时间在 2008 年 7 月至 2018 年 10 月之间。

主要观察指标

我们测量了并发症与临床因素和 NOD2(rs2076756、rs2066844 和 rs2066845)、IRGM(rs4958847 和 rs13361189)和 ATG16L1(rs2241880)中 6 个克罗恩病相关单核苷酸多态性的组合之间的关联。

结果

287 例(30%)回肠切除术中有 86 例需要干预的并发症。IRGM 基因中的 rs13361189 单核苷酸多态性与单变量和多变量分析中的并发症显著相关。61 例患者携带 rs13361189 单核苷酸多态性,其中 26 例发生并发症,而 208 例野生型患者中仅有 55 例发生并发症(43%比 26%;OR=2.1;p=0.02)。与回肠切除术后并发症相关的其他显著因素还有开放手术、近端回肠造口术和围手术期血球比容下降较大。

局限性

本研究受到其回顾性设计和固有的选择偏倚的限制。

结论

除了临床危险因素外,IRGM 基因中的 rs13361189 单核苷酸多态性也与克罗恩病回肠切除术后并发症独立相关。使用这种遗传决定因素可能会识别出术后发生手术并发症风险较高的患者。
