Which symptom is NOT indicative of a small bowel obstruction?

In the context of a small bowel obstruction, abdominal distension, pain, and vomiting are all common and indicative symptoms. They arise due to the accumulation of intestinal contents and gas as the flow is obstructed, leading to increased pressure within the bowel and resulting in discomfort, cramping, and visible swelling of the abdomen. Vomiting often occurs as the body attempts to expel the accumulated contents.

On the other hand, fever is not typically associated with a simple small bowel obstruction. While a fever can indicate an inflammatory process, infection, or perforation, it is not a hallmark symptom of a small bowel obstruction by itself. In most uncomplicated cases, the absence of bowel movement and the characteristics of the pain and distress are more critical for diagnosis rather than a rise in body temperature. Thus, in this case, identifying fever as the symptom not indicative of a small bowel obstruction is accurate.
