168例食管烧伤后瘢痕狭窄的预防和治疗

目的 总结食管烧伤后瘢痕狭窄预防和治疗的经马命。方法 168例中158例进行了172次外科治疗，11例进行了2次以上手术。早期人院Ⅱ度期以上34例采用改良食管腔内置管预防食管烧伤后瘢痕，末切除瘢痕狭窄结肠重建77例，切除狭窄食管胃重建27例，颈阔肌皮瓣修复颈部食管狭窄22例，其他类型手术12例。结果 29例拔出支撑管后治愈（85％）；5例再狭窄，其中1例扩张治愈。77例结肠重建术后5例死亡，颈部吻合口瘘14例，吻合口狭窄4例，腹部切口裂开2例。27例胃重建中，吻合口狭窄2例。脓胸1。颈阔肌皮瓣修复颈段狭窄22例中，3例发生颈部瘘。其他手术12例中，1例术后死于肠梗阻。所有生存出院患者均能进普食。 结论 管腔内置管能有效预防食管烧伤后瘢痕形成，根据瘢痕狭窄部位确定食管重建时是否切除狭窄食管。颈阔肌皮瓣是修复颈段食管狭窄或吻合口狭窄的优良方法。

Prevention and treatment of stricture after esophageal burns in 168 cases

Objective To summarize our experience in prevention and treatment of stricture after esopageal burns in the past thirty years.Methods There were 168 cases in this series.Of them,158 cases underwent surgical management in this study.Modified intraluminal stenting was used in 34 cases, colon interposition without resection of strictured esophagus in 77 cases,gastric transposion with resection of the stricture in 27,repair of cervical stricture with platysma myocutaneous flap in 22,and miscellane- ous operation in 12.Eleven cases experienced operation twice or more at our department.Results Twenty-nine cases recovered after treatment with intraluminal stenting,and 5 re-experienced stricture after stent removal.One of the 5 cases with failed stent responded to bougienage,and the remaining 4 cases re- quired esophageal reconstruction later.Of the 77 colon interpositions,5 cases died postoperatively,and complications of cervical anastomotic fistula occurred in 14 cases,anastomotic stenosis in 4,and abdomi- nal incision dehiscence in 2 cases.In the 27 cases with gastric transpositions,postoperative complications of anastomotic stricture occurred in 2 cases and empyema in 1 patient.There was a cervical leak in 3 ca- ses of the 22 cases treated with the repair of cervical esopageal or anastomotic stricture with a platysma myocutaneous flap.In the 12 cases treated with miscellaneous operation,one died of intestinal obstruc- tion.All the survivors had regular diet after discharge.Conclusions Intraluminal stenting can prevent the formation of caustic esophageal stricture.The location of the cicatricial esophagus dictates whether to perform concomitant esophagectomy during esophageal reconstruction.Platysma myocutaneous flap repair is an excellent method for the treatment of severe cervical esophageal or anastomotic stricture.
