Abstract:
:The lower esophageal high pressure zone (HPZ) was characterized manometrically and reflux status determined in eight male rhesus monkeys. The studies were repeated six weeks and six months after 50 per cent distal small bowel resection. At the same time fasting serum gastrin and gastric inhibitory polypeptide values were assayed. In seven animals precise antrectomy with gastroduodenal anastomosis was performed and the studies repeated. HPZ pressure increased from 6.7 +/-0.67 mm Hg (+/-1 SEM) to 10.3 +/- 0.76 mm Hg at six weeks (p less than 0.005). At six months the pressure was 9.3 +/- 1.02 mm Hg (p less than 0.02) and after antrectomy 15.2 +/- 3.1 (not significant from 6 month value, p less than 0.02 from control). Serum gastrin and GIP values showed significant elevations at six weeks, but six month and postantrectomy results were not statistically different from control. Reflux episodes for the group were reduced at six weeks and six months. After antrectomy increased reflux was noted.
