Comparison of emptying between gastric and colonic conduits following esophagectomy.
The emptying of gastric and colonic conduits following esophagectomy was evaluated. Ten consecutive patients who underwent esophagectomy for malignant diseases were divided into two groups as follows: Group I which consisted of 5 patients who underwent pyloroplasty and in whom the gastric greater curvature was used for reconstruction; and Group II which consisted of 5 patients in whom the colonic conduit was used because of previous gastrectomy. The conduits were placed in the retrosternal spaces in all the patients. The radiopaque markers swallowing test and digestive tract scintigraphy were performed to evaluate emptying two months after surgery. The radiopaque markers swallowing test demonstrated that marker rings quickly disappeared from the gastric conduits but remained in the colonic conduits for as long as three hours. Digestive tract scintigraphy demonstrated that there was no significant difference in the 60-minute clearance rate of 99mTc-DTPA from the conduits between the two groups. The results suggested that tiny food fragments remained in the haustral pockets of the colonic conduits, which may be a disadvantage of these conduits.
