Characteristics of gastric emptying during entire water drinking process for bowel prepa-ration in elderly patients undergoing colonoscopy under gastric antrum ultrasonography
摘要
Abstract
Objective To investigate the characteristics of gastric emptying during the entire water drinking process for bowel preparation for colonoscopy in elderly patients.Methods A total of 108 elderly patients who underwent colonoscopy in two grade A hospitals in Beijing from April to September 2024 were selected.Gastric antral cross-sectional area(CSA)was measured via single-plane ultrasonography at fasting and after five water drinking intervals.Gastric emptying rate(GER)was calculated using a standard-ized formula.Results Ninety-nine elderly patients completed gastric antral ultrasonography monitoring.The first defecation occurred between the 1st and 4th water drinking intervals.The gastric antral CSA reached its peak(mean:32.94 cm2-38.64 cm2,equivalent to 500 ml-600 ml)immediately after the 3rd water intake.Post-defecation gastric emptying rates were significantly higher than pre-def-ecation rates(47.54%-55.09%,P<0.05).Conclusions Gastric emptying is delayed during the early phase of water intake for bowel preparation in elderly patients but accelerates after the first defecation.Tailoring hydration strategies based on these gastric emp-tying characteristics may improve comfort and safety during bowel preparation.关键词
