【摘要】 肠瘘是指肠道与其他腹腔器官、腹腔或体表之间形成的异常通道。由于肠液、消化液、细菌和粪便的存在，肠瘘可导致严重感染和短肠综合征(表现为脱水、电解质失衡、营养不良)等严重临床表现。肠瘘的病因大致可分为4类：手术、创伤、疾病和先天性因素，其中前3类病因更为常见，先天性肠瘘则较为罕见。更多还原

【Abstract】 An intestinal fistula is defined as an abnormal passage that connects the intestine to another intra-abdominal organ, the abdominal cavity, or the body surface.Due to the presence of intestinal contents, digestive enzymes, bacteria, and fecal matter, intestinal fistulas can lead to severe complications such as sepsis and short bowel syndrome(manifested by dehydration, electrolyte imbalances, and malnutrition).The etiology of intestinal fistulas can be broadly classified into four categories: postoperative, traumatic, disease-related, and congenital.Among these, the first three are more commonly encountered, whereas congenital intestinal fistulas are relatively rare.更多还原
