The 'mosaic-like' pattern of portal hypertensive gastric mucosa after variceal eradication by sclerotherapy.

The 'mosaic-like' pattern of portal hypertensive gastric mucosa has been evaluated endoscopically in 38 patients referred for elective sclerotherapy, before the first session, after the complete eradication of varices and six months later. Of 38 patients studied, 18 patients exhibited mild, and 20 patients exhibited negative, findings of congestive gastropathy prior to sclerotherapy. Seventeen and 18 patients, respectively, developed aggravated changes of congestive gastropathy after the completion of sclerotherapy (P = 0.003). We consider that obliteration of varices by means of endoscopic sclerotherapy influences the development of gastric congestion changes in the majority of patients. However, further studies are required to relate the direction of blood flow in the portal system as well as the level of portal pressure with the congestive gastropathy findings in such patients.

Long-term results after esophagoplasty with colon. An endoscopic study.

Eight patients from a series of 13 having esophageal resection and colon interposition for benign disease have been evaluated by endoscopic testing, with special emphasis on the mucosal long-term changes of the colon segment and their histologic documentation. The average follow-up period was 7.2 years. All patients were in a satisfactory nutritional state but described problems associated with eating, such as regurgitation of undigested foods and substernal postprandial heartburn. No stricture was present but endoscopy confirmed the existence of food in the haustra. There was no gross evidence of colitis but the histological evaluation revealed inflammatory cell infiltration or fibrosis in all patients but one. It is believed that the main cause of mucosal damage is the prolonged cascading of food and delayed emptying, leading to digestion in the haustra.
