Which anatomical site is associated with periumbilical pain?

Periumbilical pain is typically associated with issues in the small bowel. This region of the abdomen is innervated by the T10-12 spinal nerves, which is why pain originating from the small intestine often presents in the periumbilical area. Conditions like small bowel obstruction, appendicitis (in its early stages), and other small bowel pathologies can manifest as periumbilical pain due to the anatomical and neural connections.

The bladder primarily causes suprapubic pain, while gastric issues generally lead to epigastric discomfort. Pancreatic problems often present as pain radiating to the back or epigastric region rather than specifically around the umbilicus. This anatomical understanding helps clarify why the small bowel is the relevant structure in this context.
