Abstract
The pathophysiology of postprandial distress syndrome includes impaired gastric accommodation, hypersensitivity to gastric distension and delayed gastric emptying. 2D-ultrasonography is one of the methods to assess gastric accommodation by measuring proximal gastric area and we evaluated its role in calculating proximal gastric area and thus assessing gastric accommodation in Indian patients with postprandial distress syndrome. In a hospital-based comparative analysis, proximal gastric area was measured with 2D-ultrasonography of postprandial distress syndrome(PDS) patients and compared with healthy controls. Five readings were measured every fiveminutes till 25minutes after 400mL of vegetable soup. The Patient Assessment of Upper Gastrointestinal Disorders-Quality of Life (PAGI-QOL score) and diets aggravating PDS symptoms were studied through detailed questionnaires. Sample size was calculated at 80% study power and alpha error of 0.05 to be 30 subjects in each group. The mean age of patients (18 males) vs. 30 healthy controls (25 males) was 40.8 ± 11.50years vs. 36.37 ± 7.58, respectively, (p = 0.084). Proximal gastric area was significantly lower in patients versus healthy controls at fiveminutes (22.54 ± 2.77 vs. 30.66 ± 2.55 cm2), 10minutes (23.03 ± 2.45 vs. 31.10 ± 2.06 cm2), 15minutes (23.06 ± 2.27 vs. 30.31 ± 2.11 cm2), 20minutes (22.21 ± 2.31 vs. 29.73 ± 1.71 cm2) and 25minutes (22.02 ± 2.33 vs. 28.39 ± 1.55 cm2); p < 0.001 at all intervals of time, indicating impaired gastric accommodation. The QOL was poor in all patients with PDS with mean PAGI-QOL score of 31.30 ± 15.05, median of 30, minimum score of 12 and maximum score of 66. Measurement of proximal gastric area with 2D-ultrasonography is simple and non-invasive. Proximal gastric area in patients was lower than controls, indicating impaired gastric accommodation. Poor quality of life was universal in patients with postprandial distress syndrome.
