肿瘤因素临床常见内分泌肿瘤,如胃泌素瘤易使肠道分泌量超过吸收能力,导致腹泻。肿瘤如发展到一定程度,可造成肠黏膜损伤,进而出现不规则腹泻。手术因素胃肠道肿瘤手术时,会切除部分肠段,造成肠道功能改变,导致腹泻。常见结肠肿瘤、小肠肿瘤及直肠肿瘤。 Tumor factors Common clinical endocrine tumors, such as gastrinoma, make it easier for the intestinal secretion to exceed absorption capacity, leading to diarrhea. If the tumor develops to a certain extent, it can cause damage to the intestinal mucosa and then irregular diarrhea. Surgical factors When a gastrointestinal tumor is operated, part of the bowel is removed, causing alterations in the intestinal tract and leading to diarrhea. Common colon, small intestine, and rectal tumors.
