Overview
Epidemiology and Demographics
The lifetime incidence of SBO varies between 0.1% and 5% in patients who have not undergone previous surgery, yet may rise to over 60% in patients who have undergone previous surgery. [1] [2] [3] In patients with Crohn disease, the incidence may be upward of 25%. In children, 1 in 5000 cases are reported at birth and 0.5% in the first 2 years of life. [4] [5]
Large bowel obstruction is a common symptom of colorectal cancer, with an incidence range of 15% to 29%. [2]Obstruction is also the most common indication for emergency surgery for colorectal cancer, comprising 77% of emergencies. [3]Similarly, colonic malignancy is the most common cause of large bowel obstruction in adults. [4]
For colonic volvulus, data from the US indicate an incidence of 1.47 per 100,000 per year, and 1.7 per 100,000 per year in the UK. [5] [6] Much higher incidences are reported from Africa (i.e., 12 per 100,000 per year). [1] [6] [7] [8]
Incidence
- The incidence of bowel obstruction is 1.47 per 100,000 per year in the United States.[1][2][3]
- The incidence of large bowel obstruction is approximately 15 - 29% in patients with colorectal cancer.
Prevalence
- The prevalence of small bowel obstruction is approximately 0.1 - 5% in patients who have not undergone previous abdominal surgery.
- The prevalence of small bowel obstruction is approximately 60% in patients who have undergone previous abdominal surgery.
Case-fatality rate/Mortality rate
- In [year], the incidence of [disease name] is approximately [number range] per 100,000 individuals with a case-fatality rate/mortality rate of [number range]%.
- The case-fatality rate/mortality rate of [disease name] is approximately [number range].
Age
- The incidence of bowel obstruction in newborns is 1 in 2000 live births.
- The incidence of bowel obstruction in children is 1 in 5000.
- The incidence of bowel obstruction after the first 2 years of life is 0.5%.
Race
- There is no racial predilection to [disease name].
- [Disease name] usually affects individuals of the [race 1] race. [Race 2] individuals are less likely to develop [disease name].
Gender
- [Disease name] affects men and women equally.
- [Gender 1] are more commonly affected by [disease name] than [gender 2]. The [gender 1] to [gender 2] ratio is approximately [number > 1] to 1.
Region
- The majority of [disease name] cases are reported in [geographical region].
- [Disease name] is a common/rare disease that tends to affect [patient population 1] and [patient population 2].
