Which statement concerning SBO is not true?

May lead to metabolic acidosis
Causes distention of proximal intestine
May lead to metabolic alkalosis
Causes distention of distal intestine

The correct answer is: Causes distention of distal intestine

In the context of small bowel obstruction (SBO), it is essential to understand the physiological effects of this condition. SBO primarily causes distention in the sections of the intestine that are proximal to the obstruction, not distal. When an obstruction occurs, the accumulation of fluid and gas occurs in the segment of intestine before the blockage, leading to significant distention. This proximal distention results in various complications, including risk of bowel ischemia and perforation. The other statements accurately describe the consequences of SBO. For example, severe vomiting can occur when the obstruction is high in the intestine, potentially causing metabolic alkalosis as a result of loss of gastric acid. Additionally, bowel obstruction can lead to metabolic acidosis due to the buildup of intestinal contents in the proximal loops of the bowel. Understanding these dynamics is crucial for managing patients with SBO, as the location of the obstruction heavily influences the presentation, treatment options, and potential complications.
