To review the benefit of an endoscopic surveillance programme for patients with Barrett's oesophagus.
Observational study.
University teaching hospital.
409 patients in whom Barrett's oesophagus was identified during 1984-94; 143 were entered into the annual surveillance programme.
Development of dysplasia and cancer and mortality.
The average period of surveillance was 4.4 years; 55 patients were reassessed in 1994 but only eight remained in the programme in 1999, withdrawal being due to death (not from carcinoma of the oesophagus), illness, or frailty. Five of the patients who entered surveillance developed carcinoma of the oesophagus. Only one cancer was identified as a result of a surveillance endoscopy, the others being detected during endoscopy to investigate altered symptoms. Of the 266 patients who were not suitable for surveillance, one died from oesophageal cancer and 103 from other causes. Surveillance has resulted in 745 endoscopies and about 3000 biopsy specimens.
The current surveillance strategy has limited value, and it may be appropriate to restrict surveillance to patients with additional risk factors such as stricture, ulcer, or long segment (>80 mm) Barrett's oesophagus.
回顾巴雷特食管患者内镜监测计划的益处。
观察性研究。
大学教学医院。
1984年至1994年间确诊为巴雷特食管的409例患者;143例进入年度监测计划。
发育异常、癌症的发生情况及死亡率。
平均监测期为4.4年;1994年对55例患者进行了重新评估,但到1999年只有8例仍在该计划中,退出原因是死亡(非食管癌所致)、疾病或身体虚弱。进入监测的患者中有5例发生了食管癌。仅1例癌症是通过监测内镜检查发现的,其他病例是在因症状改变而进行的内镜检查中发现的。在266例不适合监测的患者中,1例死于食管癌,103例死于其他原因。监测共进行了745次内镜检查和约3000次活检标本采集。
目前的监测策略价值有限,可能适合将监测限制在有额外风险因素的患者,如狭窄、溃疡或长段(>80mm)巴雷特食管患者。
