为了解贲门癌术后反流性食管炎的发生率和严重程度，对１９例贲门癌作部分食管胃切除左胸弓下食管胃常规端侧吻合术后病人，作食管腔内２４小时ｐＨ监测，资料由计算机软件处理。在监测期间病人能正常活动、休息、进食。结果：１９例监测时间平均２２小时４２分。以ＤｅＭｅｓｔｅｒ的评分标准１７．９６分为正常值，本组１０例（占５２．６％）属正常，无异常反流存在。９例有异常反流中８例＞５０分，属混合性反流。监测结果提示，常规手术方法术后反流发生率高且严重，在可能情况下应加作抗反流手术为宜。
In order to understand the incidence and severity of reflux esophagitis after cardial cancer surgery, 19 cases of cardiac cancer were treated with partial esophagogastric resection of the left esophagogastricus and conventional esophagogastric anastomosis. Monitoring, data processing by computer software. During the monitoring period, the patient can normally move, rest and eat. Results: The average monitoring time of 19 cases was 22 hours and 42 minutes. DeMester’s score standard was divided into 17.96 normal values, 10 cases in this group (52.6%) are normal, no abnormal reflux. In 9 cases with abnormal reflux, 8 cases were >50 points, which was mixed reflux. The monitoring results suggest that the incidence of postoperative regurgitation is high and severe in conventional surgical procedures. It is advisable to add anti-reflux surgery if possible.
