由强硷引起的食管腐蚀性灼伤,给治疗带来了很大的困难。最轻的食管灼伤可采用激素、抗菌素保守疗法。严重的透壁性食管灼伤往往由高浓度的溶液所产生,需行紧急手术,切除并分期重建食管。中度食管灼伤常继发食管狭窄,目前在治疗上还存有争论。由于使用激素、抗菌素与间断扩张治疗的效果很差,作者们因此寻求了一种腔内置放扩张子的方法。对严重食管灼伤或胃 Corrosive esophageal burns caused by strong alkaloids have brought great difficulties to the treatment. The lightest esophageal burns can be hormones, antibiotics conservative treatment. Severe transmural esophageal burns are often produced by high concentrations of solution, requiring urgent surgery, resection, and phased reconstruction of the esophagus. Moderate esophageal burns often secondary to esophageal stenosis, there is still controversial treatment.
