ABSTRACT
OBJECTIVE: To determine the nature of reflux after esophagectomy and interposition of right colon. DESIGN: A case series. SETTING: A university hospital. PATIENTS: Five patients (mean age 43 years) in whom right colon had been interposed after total esophagectomy. INTERVENTIONS: Endoscopy and biopsy, manometry, 24-hour ambulatory pH testing. MAIN OUTCOME MEASURES: Endoscopic and histologic appearances of the colon, type of motor activity in the grafted colon and the type of reflux. RESULTS: 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. CONCLUSIONS: 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.

Endobronchial lipomas are rare, benign lesions that usually obstruct a major bronchus and cause irreversible pulmonary damage distally. Because of the age, sex and smoking history of the patients in whom they are found, they also simulate malignant tumours. The authors report three cases of endobronchial lipoma. Two of the patients had a long history of cough and respiratory symptoms, the third was asymptomatic. Two patients underwent lung resection and one was managed by local resection through a bronchotomy. The lipoma in all three patients was diagnosed preoperatively and treated successfully.
