当化学灼伤性食管狭窄进行食管扩张术失败时,需外科手术治疗。疤痕性食管狭窄因属良性病变。勿需切除。且食管周围常有广泛紧密的粘连,切除时出血多,困难大。Rebertson首先报道采用胸骨后食管旁路术治疗疤痕性食管狭窄。1957年Chien等报道了60例这类病人的治疗结果,但他们的病例狭窄均未涉及全食管。我院自1977年以来对4例全食管狭窄合并咽部严重灼伤的病人进行了胸骨后结肠代食管咽部吻合术,
When a chemical burn scald esophageal stenosis fails to perform esophageal dilatation surgery is required. Scarring esophageal stricture is due to benign lesions. Do not need to remove. The esophagus is often surrounded by extensive adhesions, bleeding, removal, and difficulty. Rebertson first reported the treatment of cicatricial esophageal stenosis using a retrosternal esophageal bypass. In 1957, Chien et al. reported the results of 60 cases of these patients, but their case stenosis did not involve the entire esophagus. In our hospital since 1977, 4 cases of total esophageal stenosis with severe pharyngeal burns underwent a retrosternal pharyngeal esophagopharyngeal anastomosis.
