Abstract Background: Small bowel volvulus (SBV) is a benign gastrointestinal surgical condition in which there is a torsion of all or parts of a segment of small bowel on its mesenteric axis. It has been contributed significant burden of surgical emergency as cause of small bowel obstruction in developing countries. The main objective this study was to explore clinical and epidemiological profile of Small bowel volvulus in Northcentral Ethiopia. Method: The study was conducted at Debre Tabor General Hospital, South Gondar in Northcentral Ethiopia. The medical records of patients with a discharge diagnosis of small bowel volvulus were reviewed. The patients were seen for a 4-year period from Jan1, 2016-Dec31, 2019. The study was hospital-based retrospective cross-sectional and data were collected with a standardized structure questioner tool. The collected data checked for any inconsistency, code, and enter SPSS version 23 for data processing and analysis. Descriptive analyses were represented as frequency, percent, mean ± standard deviation for normal distribution, and Median ± Interquartile range for skewed data. Cross tabulation analysis was done for risk factors contributed for mortality and morbidity of SBV. Result: There were 148 patients with Small bowel volvulus as a cause of small bowel obstruction was admitted within 4 years. The annual occurrence rate was 35cases per year. It represented 59% of small bowel obstruction and 36.3% of bowel obstruction. The majority were males (N = 125, 84.5%) and females were (N = 23, 15.5%). The age ranged from 15 to 78 years. The mean age was 41.14 ± (SD = 15.4). The most common clinical presentation was abdominal pain 98% and vomiting 91.2%. The median time of hospital stay was 5 days (± IQR = 2). The mean duration of illness before hospital admission was 2 days (± SD = 1.4) and median was 1 day (± IQR = 2). The morbidity rate was 5.4% (N = 8) and the mortality rate was 3.4%(N = 5). Conclusion: Annual occurrence of SBV was 37 cases per year. The prevalence of SBV was 59% of small bowel obstruction and 36.3% of bowel obstruction respectively.
