Abstract:
Small bowel obstruction is a common potentially catastrophic surgical emergency in all age 
group in the world. Pattern and treatment outcome of Small bowel obstruction in eastern 
Ethiopia communities have not yet been thoroughly investigated. 
Objective: The aim of the study is to assess pattern and treatment outcome of small bowel 
obstruction among patients admitted with acute abdomen to surgical ward of HiwotFana 
Comprehensive Specialized Hospital surgical ward, harar, Ethiopia. Data was retrieved from 
September 1, 2020 – September 30, 2022. 
Method: The study was conducted among 192 cases using crossectional study design and 
following convenience sampling technique. Structured extraction format was used to collect 
relevant data. Data was interred to Epi info 7.2; analyzed using Statistical Package for the Social 
Sciences version 25 software package. Bi-variate and Multi-variate logistic regression was 
employed to assess association between dependent and independent variables with 95% CI and 
p-value less than 0.05.
Result:A total of 192 files were used; with data retrieval rate of 88.48 %.Twenty two patients 
were managed non operatively and 170 patients were operated. The mean age was 34 +
14.3years and the male to female ratio was 9:1.Simple small bowel volvulus was the 
predominant intraoperative finding (40.8%) followed by gangrenous Small bowel obstruction 
(29.8%) of any causes then Adhesion or band (21.2%). Derotation was the common procedure 
done (50%). Favorable outcome was found in 66.7% of the cases. Surgical Site Infection 
(27.5%) was the most common complication. gangrenous Small Bowel Obstruction had 91.1% 
times more likely to have unfavorable outcome compared to those with simple Small Bowel 
Obstruction (AOR-0.089 CI=95% (0.009-0.850)P-0.036.
Conclusion and Recommendation: common pattern was primary Small bowel volvulus. 
Comorbidity, Leukocytosis and having abdominal tenderness were associated with unfavorable 
outcome. Community awareness about bowel obstruction should increase to avoid late 
presentation.
