EFFECTS OF VARIOUS FORMS OF GASTRIC SURGERY ON GUT HORMONES AND PANCREATIC SECRETIONS

Effects of various forms of gastric surgery on gut hormones and pancreatic secretions were examined using canine models. These operative procedures included simple laparotomy (group A ; n=13), truncal vagotomy with pyloroplasty (B ; =17), selective proximal vagotomy (C ; n=17), proximal gastrectomy with pyloroplasty (D ; n=6), proximal gastrectomy with truncal vagotomy and pyloroplasty (E ; n=7), and distal gastrectomy (F ; n=19). The mean fasting serum gastrin and secretin levels (pg/ml) were 71.0, 82.5 in A, 94.0, 97.7 in B, 62.1, 108.1 in C, 58.2, 123.0 in D, 91.2, 138.6 in E, and 50.9, 74.5 in F, respectively. The mean value of plasma pancreatic glucagon (pg/ml) showed 73.6, 109.9, 106.8, 47.2, 37.8, and 74.5 in each of the six groups. Significant correlations were observed between values of serum lipase and those of serum gastrin as well as between the amount of pancreatic secretions and serum secretin levels. Pancreatic secretions were decreased markedly in group F and moderately in B. Basal tissue blood flow measured by hydrogen clearance method was low in D, E, and F when compared with that in A.
