目的探讨当前手术条件下胃癌术后十二指肠残端漏(DSL)的发生率,评估可能的危险因素及术后引流液检测的诊断价值。方法采用前瞻性多中心观察性研究方法,纳入国内9家诊疗中心2021年2月至2022年12月接受胃癌手术的1036例病人。术后第1、3、5、7天动态监测引流液淀粉酶及直接胆红素水平。主要研究终点为DSL发生率,次要终点包括Clavien-Dindo分级、并发症发生率及引流液生化指标动态变化。结果DSL总发生率为0.97%(10/1036),其中Clavien-Dindo分级Ⅱ级(50.0%)和Ⅲa级(30.0%)占主导。DSL组病人心脑血管合并症比例显著高于非DSL组(60.0%vs.23.7%,P=0.016),手工离断组DSL发生率显著高于器械闭合组(33.3%vs.0.9%,P=0.029)。DSL病人术后住院时间较非DSL组显著延长(24.4 d vs.10.9 d,P<0.01)。术后引流液淀粉酶及直接胆红素在DSL组呈持续升高趋势(术后第7天分别达35250.2 U/L和44.9μmol/L),但组间差异无统计学意义。所有DSL病例均通过禁食、胃肠减压、生长抑素、抗感染及充分引流治愈,无死亡病例。结论胃癌术后DSL发生率降至0.97%,器械闭合十二指肠残端安全可行。术后引流液淀粉酶及直接胆红素动态监测可能为早期诊断提供依据,但需更大样本验证。
