OBJECTIVE: Rice is the staple diet in many Asian countries. Current endoscopic guidelines advice a 6 h fast for solids and a 4 h fast for liquids before the procedure. However, these guidelines focus on a Western type diet. The aim of the study was to determine if a 6 h fast for rice is sufficient prior to upper gastrointestinal endoscopy (UGIE). PATIENTS AND METHODS: After informed consent, 212 patients referred for UGIE, who had no alarm symptoms, were randomized into two groups in preparation for UGIE. Fasting 6 h after a rice meal (R6) or fasting 10 h after a rice meal (R10). All meals contained lentils and an egg, and were isocaloric. Endoscopic vision was graded as poor, average, or good. RESULTS: In the R10 group (n = 107) vision was poor in 2 (1.9%), average in 7 (6.5%), and good in 98 (91.6%). While in the R6 group (n = 105) vision was poor in 30 (28.6%), average in 19 (18.1%), good in 56 (53.3%). The observed difference of percentages among the two groups for endoscopic vision was significant (M-H Chi-Square for trend = 25.67; df = 1; p < 0.001). CONCLUSIONS: Fasting for 6 h after a rice based meal seems inadequate for UGIE. Fasting for 10 h significantly improves endoscopic vision. Current guidelines need to be re-evaluated for populations where rice is the staple diet. |
