−
* Pancreatic tumours in particular can extend and impinge on the [[Duodenum - Anatomy & Physiology|duodenum]].
  −
* Pedicles of tumours such as lipomas in horses can become wound in loops of intestine leading to obstruction and possible strangulation.

* '''Clinical'''

** Occasional [[Control of Feeding - Anatomy & Physiology#The Vomit Reflex|vomiting]] and ntermittent [[Intestine Diarrhoea - Pathology|diarrhoea]] over several weeks. 
  −
* '''Pathogenesis'''
  −
** Seen occasionally in cat (rarer in dog)
  −
** Usually towards end of intestines
  −
*** E.g. at the ileocaecocolic valve.
  −
** Gut proximal to tumour  becomes thickened due to hypertrophy of smooth muscle as a result of trying  to force ingesta past progessively narrowing lumen.
  −
** Produces "hose pipe intestine".
  −
** Seen with carcinoma, lymphoma, leiomyoma and other tumours.[[Category:Obstruction, Intestinal]]
