Background: Sigmoid volvulus is a major cause of mechanical large bowel obstruction in volvulus belt countries. The objective of this study to explore the magnitude and clinical characteristics of Sigmoid Volvulus
Methods: Hospital-based retrospective 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 collected data checked manually for completeness and consistency. The final data 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 p=0.25 with the outcome variables were taken into a 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.
Result: There were 124 patients with sigmoid volvulus admitted within four years of the study. During the study period, 408 patients with bowel obstructions were admitted, among Mechanical large bowel obstruction (MLBO) 135 (33.1%), Mechanical small bowel obstruction (MSBO) 251(61.5%), and Ileosigmoid knotting 22(5.4%). Our study showed that sigmoid volvulus accounted for 91.9% and 30.4% of Mechanical Large bowel obstruction and Bowel obstruction respectively. Most of the patients were male 97.6 %( N=121) and rural residents 91.1 %( N=113). The peak age was 56-65 years accounted for 29 % and 65.3 %( N=81) of patients were above age 50years. The age ranged from 19-88 years. The mean and median ages were 56.52± (SD=14.4) and 58.5± (IQR=17.75) respectively. The mean of hospital stay for elective admission was 10.98(SD±4.33) days and the median was 11 (IQR±5) days. The mean of hospital stay for emergency admission excluding death and leave against medical advice was 8.4(SD±4.1) days and median was 8 (IQR±2) days
Conclusion: Primary resection and anastomosis was the common procedure for management of sigmoid volvulus. Mortality rate was 6.45% and higher in gangrenous sigmoid volvulus (14.6 % vs. 2.4%)
