作者在四年内对35例不同原因的食管狭窄应用胶囊导管进行了170次扩张,其中返流性食管炎13例(每例平均扩张5.07次)、手术吻合狭窄8例(平均3.75次)、肿瘤性狭窄7例(平均3.71次)、吞食腐蚀性物质所致狭窄4例(平均7次)和失弛缓症3例(平均6.33次)。扩张前每例均进行食管造影以观察狭窄的程度、偏心性、长度以及有无胃食管返流和食管憩室。有的病例还作食管镜检,以取得病理资料。术前用阿托品和安定,术中常需用镇静剂和止痛剂,并建立输液通道。操作在透视监视下进行。用金属夹钳标记出狭窄的上下界限。经鼻插入血管造影转向导管和导丝,并使导丝通过狭窄,
In four years, 35 patients with esophageal stenosis were enrolled in this study. In 170 cases, there were 170 cases of esophageal stenosis, including 13 cases of reflux esophagitis (average 5.07 times per case), 8 cases of anastomotic stenosis (average 3.75), tumor There were 7 cases of stenosis (3.71 on average), 4 cases of esophageal stenosis (average 7), and 3 cases of achalasia (6.33 on average). Each case before the expansion of esophageal angiography to observe the extent of stenosis, eccentricity, length and the presence of gastroesophageal reflux and esophageal diverticulum. Some cases also for esophageal microscopy to obtain pathological data. Preoperative use of atropine and stability, surgery often require sedatives and analgesics, and the establishment of infusion channel. Operation is under fluoroscopy. Metal clamp marks the narrow upper and lower boundaries. Transcranial angiography Steering catheter and guide wire, and the guide wire through the narrow,
