GASTRIC-EMPTYING AFTER PYLORUS-PRESERVING GASTRECTOMY IN COMPARISON WITH CONVENTIONAL SUBTOTAL GASTRECTOMY FOR EARLY GASTRIC-CARCINOMA

It is well known that surgical intervention on the stomach will greatl y alter gastric function and gastric emptying, In this study, we evalu ated the difference in postoperative gastric remnant emptying followin g pylorus-preserving gastrectomy (PPG) and conventional subtotal gastr ectomy (CDG) using sulfamethizole capsule food, The subjects comprised 18 patients who underwent PPG and 23 who underwent CDG for early gast ric carcinoma. While delayed gastric emptying was observed early after PPG, 1 year after PPG it was markedly accelerated compared with that measured in the early postoperative period. However, it was slower tha n that in the CDG patients. On the other hand, rapid gastric emptying was observed early after CDG and did not change with time. These findi ngs stress that although PPG results in stasis in the early postoperat ive period, it seems to prevent unduly rapid emptying.
