Comparison of gastric emptying of solid and semi-solid meals using real-time ultrasonography in healthy Sri Lankan adults

Gastric emptying, residual antral cross-sectional area and antral motility of a semisolid meal are almost similar to that of a solid meal of the same nutritional value until three hours post-ingestion. A semisolid test meal can effectively substitute a solid test meal during ultrasound assessment of gastric emptying, without compromising the validity of the results. Additionally, the ease of preparation and administration of semisolid meals enhances the overall feasibility of gastric emptying assessments.
