Postoperative reflux esophagitis is a common complicationafter partial removal of the esophagus and the whole gastriccardia for reconstruction through esophagogastrostomy. In 10cases, the lower esophageal sphincter (LES) was preserved fora length of 2.05± 0.33cm ((?)±S)during partialesophagectomy for benign or malignant lesion at the middleand lower portion of the thoracic esophagus. The mean valueof the LES pressures measured two weeks after operations was2.40±0.64 kPa (18± 4.8 mmHg) and the postoperative X-raybarium meal examination revealed no evidence ofgastroesophageal reflux. Our study suggested that the pre-served LES should effectively act as a functional barrieragainst the development of reflux esophagitis.
