We experienced 8 cases of esophageal cysts on between January, 1965 and March, 1989. During the same period, 320 cases of mediastinal tumors were operated in our department, and esophageal cysts were 2.5% of these cases. They were 7 males and 1 female, and ranged in age from 5 to 51 (mean 29.9) years. The cysts were located in the right in 6 and in the left in 2, and in the upper third of the esophagus in 1, middle third in 3 and lower third in 2 cases. A correct preoperative diagnosis was made in only 1 case. The definite diagnoses were not obtained from thoracic CT scans and esophagography. We tried transesophageal ultrasonic endoscopy in the recent 2 cases, and could diagnosed in 1 case as a cyst in the esophageal wall. The another case, we could not diagnose, was a cyst attached to the esophageal wall by a muscular stalk. We experienced 2 cases of post operative bleedings, so we must be careful of hemostasis of the muscular layers after enucleation of the cysts. Histological examinations of the cysts showed ciliated columnar epithelium in all cases. Cartilage were observed (bronchogenic cysts) in 4 patients (50%) and two muscle layers were observed (duplication cysts) in 4 other patients (50%). But 2 cases of bronchogenic cysts had two muscular layers, 1 case of them was well-defined. And 1 case of duplication cyst had poor two muscular layers. We cannot divide clearly the esophageal cysts into bronchogenic cyst or duplication cyst, in the point of having cartilage and double muscle layers.(ABSTRACT TRUNCATED AT 250 WORDS)
1965年1月至1989年3月期间，我们共收治8例食管囊肿。同期，我科共进行320例纵隔肿瘤手术，食管囊肿占这些病例的2.5%。患者中男性7例，女性1例，年龄范围为5至51岁（平均29.9岁）。囊肿位于右侧6例，左侧2例；位于食管上三分之一处1例，中三分之一处3例，下三分之一处2例。术前仅1例做出正确诊断。胸部CT扫描和食管造影均未明确诊断。最近2例我们尝试了经食管超声内镜检查，1例诊断为食管壁囊肿。另一例，囊肿通过肌性蒂附着于食管壁，未能诊断。我们有2例术后出血，因此囊肿摘除后必须注意肌层止血。囊肿的组织学检查显示，所有病例均为纤毛柱状上皮。4例患者（50%）观察到软骨（支气管源性囊肿），另外4例患者（50%）观察到两层肌肉（重复囊肿）。但2例支气管源性囊肿有两层肌肉，其中1例界限清晰。1例重复囊肿的两层肌肉不明显。从有无软骨和双层肌肉来看，我们无法明确将食管囊肿分为支气管源性囊肿或重复囊肿。（摘要截选至250字）
