Large bowel obstruction, Ethiopia, Sigmoid volvulus



Background: Mechanical Large Bowel Obstruction (MLBO) has been contributed significant burden of emergency admission.

Objective: To determine the magnitude of mechanical large bowel obstruction and outcome predictors for morbidity and mortality in Debre Tabor General Hospital Northcentral Ethiopia, 2020

Methods: Hospital-based cross-sectional study employed in Debre Tabor general hospital Northcentral Ethiopia. A medical review conducted on the medical chart from Jan1, 2016 to Dec31, 2019. The reviewed data checked manually for completeness, consistency, coded and entered to SPSS version 23 for data processing and analysis.  Binary logistic regression used to measure the association of each covariate with the outcome variable. In addition, factors that have an association with the outcome variables were taken into multivariable logistic regression analysis to control the potential confounders. The result of the final model expressed in terms of adjusted Odd Ratios (AOR) and 95% CI and statistical significance declared if the P-value is less than 0.05. 

Results: Mechanical Large bowel Obstruction (MLBO) was accounted 33.1 %( 135) of bowel obstruction. Majority of MLBO were males (N=129, 95.6%).The mean and median age were 56.56(SD=±14.58) and 58(IQR±18) respectively. Over all mean of hospital stay was 8.65 (SD±4.8) days and the media was 8(IQR±5) days. The leading etiologies of mechanical large bowel obstruction were sigmoid volvulus (N=124, 91.9%) and colorectal cancer (N=7, 5.2%). Overall complication rate was 21.5 %( N=29) and mortality rate was 8.9 %( N=12

Conclusion: Sigmoid volvulus was the most common cause of mechanical large bowel obstruction.
