回肠造口性腹泻的早期识别和处理的研究进展

回肠造口术作为外科治疗的常见术式，术后患者常因失去结肠对消化液的吸收引起水、电解质丢失增加，处于相对液体耗尽的状态。回肠造口术后几周内机体存在液体吸收增加的适应过程，但常有患者无法充分适应，造口液大量丢失，也会有其他原因导致回肠造口性腹泻。许多回肠造口性腹泻患者有脱水和电解质丢失的风险，需再入院治疗，消耗大量的医疗资源。外科医生除掌握肠造口手术技术外，应深入对其病理生理的认识，以便实施针对性治疗。笔者对回肠造口性腹泻发病机制及治疗作一综述，以期为此类患者的治疗提供参考。

Research progress of early recognition and treatment of ileostomy diarrhea

Ileostomy is a common procedure in surgical practice. After this procedure, the patients may be in a state of relative fluid depletion due to the increased fluid and electrolyte losses resulting from the loss of colonic absorption. Within weeks after ileostomy creation, there is a body adaptation process of increased fluid absorption. However, some patients will fail to adapt adequately and have a large volume of ileostomy output, or will develop ileostomy diarrhea due to other causes. Many patients with ileostomy diarrhea are at risk of dehydration and electrolyte loss, and often require hospital readmission, which consumes a lot of medical resources. Except for the mastery of surgical skills of ileostomy, surgeons should fully understand its pathophysiological processes, so as to allow the implementation of targeted treatment. Here, the authors address the pathogenesis and treatment of ileostomy diarrhea, hoping to provide a reference for the treatment of patients with this condition.
