What is the definition of a bowel obstruction?

A bowel obstruction is defined as a partial or complete block of the small or large intestine. This definition encompasses both types of obstructions, which can prevent the passage of contents through the bowel, leading to various symptoms such as abdominal pain, vomiting, and constipation. The obstruction can result from various causes, such as adhesions, tumors, hernias, or strictures, and can affect either part of the gastrointestinal tract.

On the other hand, the other definitions listed do not accurately represent a bowel obstruction. For instance, a complete halt of digestive processes is too broad and doesn't specifically refer to the blockage of the bowel. Similarly, a complete tear of the intestines, known as a perforation, is a different medical condition that leads to leakage of intestinal contents into the abdominal cavity and is not simply a blockage. Lastly, a blockage that only affects the large intestine doesn't encompass the totality of what a bowel obstruction can involve, as obstructions can occur in both the small and large intestines. Thus, the stated definition effectively captures the essence of what a bowel obstruction entails.
