To determine the nature of reflux after esophagectomy and interposition of right colon.
A case series.
A university hospital.
Five patients (mean age 43 years) in whom right colon had been interposed after total esophagectomy.
Endoscopy and biopsy, manometry, 24-hour ambulatory pH testing.
Endoscopic and histologic appearances of the colon, type of motor activity in the grafted colon and the type of reflux.
In all patients the grafted colon was macroscopically and microscopically normal. There was nonperistaltic motor activity in the interposed colon in two patients. All patients had an abnormal pattern of alkaline reflux, and one patient had abnormal acid reflux.
The clinical effect of alkaline reflux in patients with colonic interposition after total esophagectomy may be slight. Histologic and gross changes are likely to be minimal.
确定食管切除及右半结肠间置术后反流的性质。
病例系列。
一家大学医院。
5例患者（平均年龄43岁），均在全食管切除术后行右半结肠间置术。
内镜检查及活检、测压、24小时动态pH值检测。
结肠的内镜及组织学表现、移植结肠的运动活性类型及反流类型。
所有患者的移植结肠在宏观和微观上均正常。2例患者的间置结肠存在非蠕动性运动活性。所有患者均有异常的碱性反流模式，1例患者有异常的酸性反流。
全食管切除术后结肠间置患者碱性反流的临床影响可能较小。组织学和大体变化可能很轻微。
