| 1 | Performance of American Society for Gastrointestinal Endoscopy guidelines for dyspepsia in Saudi population: Prospective observational study显示文摘AIM: To evaluate adherence of primary care physicians(PCPs) to international guidelines when referring patients for upper-gastrointestinal endoscopy(UGE), evaluate the importance of alarm symptoms and the performance of the American Society for Gastrointestinal Endoscopy(ASGE) guidelines in a Saudi population.METHODS: A prospective, observational cross-sectional study on dyspeptic patients undergoing UGE who were referred by PCPs over a 4 mo period. Refer-rals were classified as appropriate or inappropriate according to adherence to ASGE guidelines.RESULTS: Total of 221 dyspeptic patients was enrolled; 161 patients met our inclusion criteria. Mean age was 40.3 years(SD ± 18.1). Females comprised 70.1%. Alarm symptoms included low hemoglobin level(39%), weight loss(18%), vomiting(16%), loss of appetite(16%), difficulty swallowing(3%), and gastrointestinal bleeding(3%). Abnormal endoscopy findings included gastritis(52%), duodenitis(10%), hiatus hernia(7.8%), features suggestive of celiac disease(6.5%), ulcers(3.9%), malignancy(2.6%) and gastroesophageal reflux disease(GERD: 17%). Among patients who underwent UGE, 63% met ASGE guidelines, and 50% had abnormal endoscopic findings. Endoscopy was not indicated in remaining 37% of patients. Among the latter group, endoscopy was normal in 54% of patients. There was no difference in proportion of abnormal endoscopic findings between two groups(P = 0.639).CONCLUSION: Dyspeptic patients had a low prevalence of important endoscopic lesions, and none of the alarm symptoms could significantly predict abnormalendoscopic findings. | Nahla A Azzam Majid A Almadi Hessah Hamad Alamar Lamis Atyah Almalki Rehab Nawaf Alrashedi Rawabi Saleh Alghamdi Waleed Al-hamoudi | 2015 | World Journal of Gastroenterology2015，21，2： | 2 |
