What's the difference between stenosis and stricture?

Stenosis


Definition:

  • (n.) A narrowing of the opening or hollow of any passage, tube, or orifice; as, stenosis of the pylorus. It differs from stricture in being applied especially to diffused rather than localized contractions, and in always indicating an origin organic and not spasmodic.

  • (19) The concomitant reduction in aortic pressure and increase in heart rate following total occlusion of the portal vein were most pronounced during the first weeks after stenosis, and were probably due to diminished venous return to the heart.
  • (20) The average size of stenosis after dilation was 32%.

Stricture


Definition:

  • (n.) Strictness.
  • (n.) A stroke; a glance; a touch.
  • (n.) A touch of adverse criticism; censure.
  • (n.) A localized morbid contraction of any passage of the body. Cf. Organic stricture, and Spasmodic stricture, under Organic, and Spasmodic.
