Esophageal strictures following nasogastric intubation.

Esophageal stricture is not reported to be a common complication of nasogastric intubation. Two patients who had a Levin tube inserted in the stomach for nutrition during a prolonged coma, and finally presented with a severe esophageal stricture were observed and treated. The clinical history of the patients suggests that the pathogenesis of this lesion is probably multifactorial, secondary to induced gastroesophageal reflux, impaired esophageal clearance, high gastric acid output, and use of steroids. Jejunostomy feeding, rather than nasogastric feeding, is probably a better means to provide nutritional support in comatose patients, thus averting the risk of such a serious complication. Esophageal replacement with left colon interposition appears the treatment of choice for these severe esophageal strictures.
