25. Evaluating anal canal pressure and rectal sensation of dyssynergic defecation patients in HRAM
Main Article Content
Abstract
This study evaluated clinical symptoms, anal canal pressures and rectal sensation levels on high - resolution anorectal manometry (HRAM) in patients having dyssynergic defecation (DD). This is a cross-sectional study of 52 patients aged ≥ 18 years old, with suspected symptoms of DD and were later diagnosed with DD in HRAM between March 2022 and August 2022 at the Institute of Gastroenterology and Hepatology. The results showed that the most common symptoms were incomplete evacuation feeling (88.5%), straining (69.2%), sensation of anorectal obstruction (62.5%) and constipation (51.9%). Type II was the most popular type in DD (48%). There was no difference among 4 types in clinical symptoms and HRAM values. The proportions of anal hypotension was 15.4%, anal hypertension was 9.6%, anal hypocontractility was 3.8% and rectal hyposensitivity was 7.7%. In conclusion, the symptoms of DD were various and not specific. Although type II was the most common in DD, there were no difference in clinical symptoms and HRAM values among 4 types.
