Background: Sub-acute intestinal obstruction resulting from intestinal tuberculosis is more prevalent in developing countries including Bangladesh.
Objective: To evaluate the prevalence of intestinal tuberculosis in sub-acute intestinal obstruction in relation to age, sex, social class, occupation and residence.
Methods: This Prospective observational cross sectional study was done at Rangpur Medical College Hospital, Rangpur from December2013 to June 2014 where 50 patients were selected by purposive sampling as a diagnosed case of sub acute intestinal obstruction. During the study in formed written consent was taken from each of the patients or legal guardians before taking any interview. The consent form clearly describes the purpose and method of the study. After enrollment of the relevant data from history, physical examination and investigations, the information was recorded in predesigned case record form.
Results: The data analysis of 50 patients yielded the following results. Among the 50 patients with sub-acute intestinal obstruction, 20 (40%) patients were from 31-40 years age group followed by 41-50 years age group where the numbers of respondents were 15(30%). Male to female ratio was 4:1. 72% respondents were rural people.
Conclusion: Prevalence of sub-acute intestinal obstruction due to intestinal TB is increasing in TB-endemic countries such as south-east Asia. Due to the lack of characteristic specific symptoms and signs and the fact that laboratory findings are commonly non-specific or show no abnormality, diagnosis of such cases is difficult. Further studies are needed for better outcome.
