Constant suction is maintained through the nasojejunal tube, which has been threaded through and beyond the anastomosis. During this period alimentation is maintained with intravenous fluids and supplemental vitamins. The patient is ambulated on the first postoperative day, and a gradual increase in activity is encouraged. Early return of peristaltic activity to the bowels may be stimulated by injecting 30 mL of mineral oil through the jejunal tube at regular intervals during the first few postoperative days. When intestinal peristalsis has been established, the suction may be discontinued. A slow administration of feedings low in fat and carbohydrate content will avoid diarrhea. Usually, only water followed by skim milk is given in 30- to 60-mL amounts as tolerated. Oral feedings can be instituted as soon as there is complete assurance that no fistula has formed at the sites of anastomosis. This may be verified by fluoroscopic x-ray studies using a water-soluble contrast dye. These patients, of course, will need frequent small feedings, and adequate caloric intake will be a problem. The family will require instructions regarding diet. This calls for careful collaboration between surgeon and dietitian. In addition, supplemental vitamin B12 will be necessary at monthly intervals. Oral iron and vitamins may be indicated for life.
