The outlet obstruction (OO) rate is 5.4-18.4% after defunctioning ileostomy (DI) following rectal cancer resection to reduce the incidence and severity of anastomotic leakage; OO affects a patient's quality of life and prolongs hospitalization.
A retrospective analysis was performed of patients who underwent anterior rectal resection and DI for rectal cancer.
Among 100 patients undergoing anterior rectal resection with DI for rectal cancer, 28 (28%) developed OO. Anastomotic leakage and a rectus abdominis muscle thickness ≥10 mm on preoperative computed tomography were significantly associated with the risk of OO in univariate analysis. Multivariate analysis also demonstrated that anastomotic leakage (odds ratio=4.320, 95% confidence interval=1.280-14.60, p=0.019) and rectus abdominis muscle thickness ≥10 mm (odds ratio=3.710, 95% confidence intervaI=1.280-10.70, p=0.016) were significantly risk factors for OO.
When OO is observed, an anastomotic leakage should be suspected, especially if there is a high rectus abdominis muscle thickness.
直肠癌切除术后行去功能化回肠造口术（DI）以降低吻合口漏的发生率和严重程度，其出口梗阻（OO）发生率为5.4% - 18.4%；OO会影响患者生活质量并延长住院时间。
对因直肠癌接受直肠前切除术和DI的患者进行回顾性分析。
在100例因直肠癌接受直肠前切除术并进行DI的患者中，28例（28%）发生了OO。在单因素分析中，吻合口漏和术前计算机断层扫描显示腹直肌厚度≥10 mm与OO风险显著相关。多因素分析还表明，吻合口漏（比值比 = 4.320，95%置信区间 = 1.280 - 14.60，p = 0.019）和腹直肌厚度≥10 mm（比值比 = 3.710，95%置信区间 = 1.280 - 10.70，p = 0.016）是OO的显著危险因素。
当观察到OO时，应怀疑存在吻合口漏，尤其是在腹直肌厚度较高的情况下。
