The first use of an overtube to assist endoscopy was described more than 20 years ago. Since then a number of uses of overtubes have been described, but relatively few complications have been reported. We report a case of esophageal perforation caused by overtube insertion during endoscopic band ligation of varices. This case is unique in that the patient presented 13 days after the original procedure, and it is the first reported case of esophageal injury involving the modified Bard overtube. The existing literature involving overtube injury is also reviewed.
20多年前就有使用外套管辅助内镜检查的描述。从那时起，已有多种外套管的用途被描述，但报道的并发症相对较少。我们报告1例在内镜下静脉曲张套扎术期间因插入外套管导致食管穿孔的病例。该病例的独特之处在于患者在原手术13天后出现症状，并且是首例报道的涉及改良巴德外套管的食管损伤病例。同时还对现有的关于外套管损伤的文献进行了综述。
