Functional conduit disorders after esophagectomy.
Unfortunately normal gastrointestinal function after an esophagectomy is rare. Most patients will never eat the way they did before their illness. Most patients require smaller more frequent meals. It is common for patients to loose up to 15% of their body weight from the time of diagnosis through the first 6 months postoperatively, but fortunately this trend levels off after 6 months. Dumping syndrome, delayed gastric emptying, reflux, and dysphagia can all contribute to nutritional deficiency and poor quality of life. There is no one surgical modification to eliminate any one of these complications, but several guidelines can help reduce conduit dysfunction. Most patients seem to benefit from a 5-cm-wide greater-curvature gastric tube brought up through the posterior mediastinum. The gastric-esophageal anastomosis should be placed higher than the level of the azygous vein. Drainage procedures seem to be helpful, especially when using the whole stomach as a conduit. Early erythromycin therapy significantly aids in the function of the gastric conduit. Proton-pump inhibitors are important for improvement of postoperative reflux symptoms and to help prevent Barrett's metaplasia in the esophageal remnant. Single-layer hand-sewn or semi-mechanical anastomoses provide greater cross-sectional area and fewer problems with stricture. When benign strictures occur, early endoscopy and dilation with proton-pump inhibition greatly reduces the morbidity. Patients should be instructed to eat six small meals a day and to remain upright for as long as possible after eating. Simple sugars and fluid at mealtime should be avoided until the function of the conduit is established.
