Esophageal manometry was performed in a group of extremely obese subjects in order to investigate the lower esophageal sphincter (LES) pressure and its relationship to extreme obesity, weight reduction and altered anatomy of the stomach. Forty subjects were examined before gastric surgery for treatment of their obesity, and 14 of these were reexamined after weight reduction. Normal LES pressure (20 mmHg) was found before operation, and also normal length and position of the LES. No significant changes were found in the group which was examined twice. In persons younger than 50, LES manometric findings do not seem to be influenced by extreme obesity, weight reduction or gastric surgery for obesity.
为了研究食管下括约肌（LES）压力及其与极度肥胖、体重减轻和胃部解剖结构改变的关系，对一组极度肥胖的受试者进行了食管测压。40名受试者在接受治疗肥胖的胃部手术前接受了检查，其中14人在体重减轻后再次接受检查。术前发现LES压力正常（20 mmHg），LES的长度和位置也正常。在接受两次检查的组中未发现显著变化。在50岁以下的人群中，LES测压结果似乎不受极度肥胖、体重减轻或肥胖症胃部手术的影响。
