我院自１９８６年～１９９５年对４９２例来自全国的食管（贲门）癌切除术后吻合口狭窄者，应用“自制多功能食管扩张器”（已获国家专利：ＺＬ９５２１５６１０．５）和Ｊａｐａｎ－ｄｉｌａｔｏｒ进行扩张术加药物治疗（中药：开膈散、通关口服液），有效率９８％，无严重并发症，死亡率为０。这种方法对各类吻合口狭窄的疗效均感满意，尤其适用于老年、体质差者，可避免再次开刀施行手术狭窄成型或切除狭窄再吻合的痛苦或手术死亡的危险。这种自制“多功能食管扩张器”，吸取国内外扩张器的优点，克服其不足之处，设计合理、痛苦小、并发症少、扩张力度大、效果好。对吻合口重度狭窄者扩张术前辅以中药，疗效理想。本组病例，不包括癌复发。
In our hospital from 1986 to 1995, 492 cases of anastomotic stenosis after resection of esophagus (cardia) from the whole country were treated with the “self-made multifunctional esophageal dilator” (National Patent: ZL95215610.5) and Japan-dilator. Expansion and drug treatment (Chinese medicine: Kailuan San, Tongguan Oral Solution) have an effective rate of 98%, no serious complications, and a mortality rate of 0. This method is satisfactory for all kinds of anastomotic stenosis curative effect, especially for elderly, poor quality, to avoid the risk of re-surgical stenosis or stenosis re-anastomosis pain or surgical death. This self-made “multi-functional esophageal dilator” draws on the advantages of both domestic and foreign dilators to overcome its deficiencies. It has a rational design, less pain, fewer complications, and a large expansion force with good results. It is ideal for the treatment of severe anastomotic stenosis before supplementation with traditional Chinese medicine. This group of patients does not include cancer recurrence.
