Abdominal Ultrasonography in Sitting Position and Water-Filled Stomach for Improve Visualization of Pancreas
Keywords:
Pancreas, Sitting position, UltrasonographyAbstract
ABSTRACT
Objective: Abdominal ultrasonography is accurate and used to examine the many organs but it has a limitation to evaluate pancreas. The limitations cause by gasses in the gastrointestinal tract which obscured underlying structures. The technique can improve visualization of ultrasonography of pancreas which scans in sitting position with water-filled stomach. Although gas in the stomach and small bowel is the main reason for poor visualization of pancreas, this technique is not common use in Thailand.
Methods: This study was a prospective study which collected data during July-September 2021. A total of 236 patients undergoing abdominal ultrasonography in routine abdominal ultrasonography of pancreas then each patient scanned twice. The second scan of pancreas was performed after patients had drunk about 300 ml of water in sitting position. The data were collected in demographic data including age, sex, weight and height. A descriptive statistic was used by frequency, percentage, mean and standard deviation. Paired sample t-test was used in statistical analyzing the data.
Results: There were improve visualization of pancreatic ultrasonography in sitting position with water-filled stomach compared to the routine scan (2.61± 0.56 vs 1.52± 0.83), p= .000. In overweight, obese and extremely obese patients, the overall improve visualization of pancreatic ultrasonography using sitting position with water-filled stomach compared to the routine scan (2.45± 0.60 vs 1.26± 0.78), p= .000.
Conclusion: This study concluded that abdominal ultrasonography using water-filled stomach in sitting position improves visualization of pancreas.
