小肠出血性病灶常难于诊断和定位、为进行合理和有效的治疗,病灶定位却很重要.由于小肠活动度大和长,钡剂、同位素扫描和选择性动脉造影只能初步提示病变的位置,精确诊断有赖于术中检查.本文介绍对小肠出血时术中作定位检查的经验.材料和方法:1979～1985年诊治小肠出血性病变25例,包括肿瘤、溃疡、动静脉畸形、息肉和憩室.其中1例因出血量大需急症手术,术前未作检查.其余24例都作术前检查,包括胃肠钡餐、纤维胃镜、钡灌肠和结肠镜等,以排除食管、胃、十二指肠和结直肠的病变.如病灶在小肠则作钡餐、小肠灌洗、~(99m)锝标记红细胞扫描和/或选择性腹腔动脉及肠系膜动脉造影,以初步确
Small intestine hemorrhagic lesions are often difficult to diagnose and locate, in order to carry out reasonable and effective treatment, lesion localization is very important because of small and large intestine mobility, barium, isotope scanning and selective arteriography can only suggest the location of the lesion, accurate The diagnosis depends on the intraoperative examination.This paper introduces the experience of small intraoperative bleeding during operation for positioning.Materials and methods: From 1979 to 1985, 25 cases of small intestinal hemorrhagic disease were diagnosed and treated, including tumors, ulcers, arteriovenous malformations, polyps and diverticula. Among them, 1 patient had emergency surgery due to large amount of bleeding and had not been examined preoperatively.The remaining 24 patients were examined preoperatively, including gastrointestinal barium meal, fiber endoscopy, barium enema and colonoscopy to exclude the esophagus, stomach, Intestinal and colorectal lesions such as lesion in the small intestine as barium meal, small bowel lavage, ~ (99m) technetium-labeled red blood cell scan and / or selective celiac artery and mesenteric artery angiography to preliminary
