Obstruction of small intestine

Description

Hindrance of the passage of luminal contents in the small intestine. Obstruction of the small intestine can be partial or complete, and caused by intrinsic or extrinsic factors.

Strangulating obstruction is associated with impaired blood flow to the small intestine in addition to obstructed flow of luminal contents.
