The assessment of the result of surgery for peptic ulcer is based on doctor-determined criteria. Failure to distinguish one operation as being better than another may be because these criteria do not include the patient's rating of outcome. A questionnaire based on patients' descriptions of the quality of result has been tested in 63 patients. Preliminary figures show that success in the opinion of the patient does not necessarily mean absence of symptoms, while failure is due more to psychosocial than physical factors. A logical step in the planning of controlled trials is preoperative control of admission to the trial.
消化性溃疡手术结果的评估是基于医生确定的标准。未能区分一种手术比另一种更好，可能是因为这些标准没有包括患者对结果的评价。一份基于患者对结果质量描述的问卷已在63名患者中进行了测试。初步数据表明，在患者看来，成功并不一定意味着没有症状，而失败更多是由于心理社会因素而非身体因素。在对照试验规划中的一个合理步骤是术前对试验入选进行控制。
