Nutritional effects according to reconstructional methods after total gastrectomy

Abstract

Malnutrition and weight loss after total gastrectomy is one of the major concerns of surgeons. In order to improve the nutritional status in these patients, many surgeons have tried to restore the duodenal passage as reconstructive procedure but debates have been continued. So we investigated weight change, postprandial serum secretin response and fecal fat amount to evaluate the esophagojejunoduodenostomy after which the duodenal passage was restored. Total gastrectomized dogs showed significant weight loss and all experimental animals except sham operation died between five and eight weeks after the operation. Serum secretin concentration after esophagojejunoduodenostomy increased significantly from a mean fasting value of 100 ± 12.5 pg/mL to a mean peak of 142 ± 22.5 pg/mL at 40 minutes and returned to the fasting level at 120 minutes postprandially. But fasting and postprandial serum secretin concentration in patients following Roux-en Y esophagojejunostomy were fluctuated irregularly. The amount of fecal fat in esophagojejunoduodenostomy was 5.3 ± 1.2 gm/100 gm stool, which was not different from that of the control group but in Roux-en Y esophagojejunostomy it was 28.1 ± 4.1 gm/100 gm stool which was much higher than that observed in esophagojejunoduodenostomy and in control group. These results suggest that esophagojejunoduodenostomy is superior to Roux-en Y esophagojejunostomy in respect to pancreatic secretory function and fat absorption.
