总结3例肠外瘘患者行瘘口内插管转流技术的护理经验。针对本组患者肠外瘘排泄量大、肠液收集困难、瘘口位置特殊（临近切口或位于切口内）、创面管理难及营养不良等问题，采取瘘口内插管转流、套囊压力监测、拔管护理、创面管理及营养支持等措施。经严密监护和精准管理，本组患者1例瘘口自愈，2例二期行肠瘘修补手术，均痊愈出院。

This article summarizes the nursing experience of three patients with enterocutaneous fistula who underwent intra-fistula intubation diversion technique. Addressing challenges such as high output of fistula drainage，difficulty in collecting intestinal fluid，special fistula locations（adjacent to or within the surgical incision），difficulty in would management and malnutrition，interventions included intra-fistula intubation diversion，cuff pressure monitoring，catheter removal care，specialized wound management，and nutritional support. Through meticulous monitoring and precise management，one patient achieved spontaneous fistula closure，while the other two underwent secondary fistula repair surgery. All patients recovered and were discharged successfully.
