Diagnostic value of plain abdominal radiography in stroke patients with bowel dysfunction.

Abstract

ObjectiveTo evaluate the diagnostic value of plain abdominal radiography in stroke patients with bowel dysfunction.MethodsA total of 59 stroke patients were recruited and assigned into constipation or non-constipation group. Patients were interviewed to obtain clinical information, constipation score, and Bristol stool form scale. The total and segmental colon transit time (CTT) was measured using radio-opaque markers (Kolomark). The degree of stool retention was evaluated by plain abdominal radiography and scored by two different methods (Starreveld score and Leech score). The relationship between the clinical aspects, CTT, and stool retention score using plain abdominal radiography was determined.ResultsAverage constipation score was 4.59±2.16. Average Bristol stool form scale was 3.86±1.13. The total and segmental CTTs showed significant differences between the constipation and non-constipation groups. There was statistically significant (p<0.05) correlation between the total CTT and constipation score or between Starreveld score and Leech score. Each segmental CTT showed significant correlation (p<0.05) between segmental stool retention scores.ConclusionThe stool retention score showed significant correlation with constipation score as well as total and segmental CTT. Thus, plain abdominal radiography is a simple and convenient method for the evaluation of bowel dysfunction in stroke patients.
