New manometric techniques in for examining the lower oesophageal sphincter (LOS) were applied an investigation of the oesophago-gastric junction after partial gastric resection. Pressure and blood gastrin data are reported for eight cases examined before and after surgery, under basal conditions and after stimulation with a protein meal. It was found that gastric resection leads to a decrease in LOS performance (43.6% fall in maximum pressure) and length (-33.3%). There is also a 93.5% decrease in the pressure response to a protein meal, and hence a predisposition to gastroesophageal reflux.
用于检查食管下括约肌（LOS）的新测压技术被应用于部分胃切除术后食管胃交界处的研究。报告了8例患者手术前后在基础状态和蛋白质餐刺激后的压力及血胃泌素数据。发现胃切除导致食管下括约肌功能下降（最大压力下降43.6%）和长度缩短（-33.3%）。对蛋白质餐的压力反应也下降了93.5%，因此易发生胃食管反流。
