Gastric stasis must be differentiated from gastric dilation which is usually associated with intestinal obstruction. See Harcourt Brown F M (2007), Gastric dilation and intestinal obstruction in 76 rabbits Veterinary Record 161 409 – 414 and Harcourt Brown T R (2007) Management of Acute Gastric Dilation in Rabbits Journal of Exotic Pet Medicine 16 (3) 168 – 174.

==Pathophysiology==
===The difference between gastric dilation and gut stasis===
Gastric dilation develops rapidly, suddenly and unexpectedly, whereas gut stasis develops slowly and insidiously, usually followed by a painful or stressful episode. Note that a moving foreign body could mimic gut stasis except that the stomach is not impacted (stomach may or may not be impacted).
===Pathophysiology===
(Pathological) obstruction of small intestine accompanied by (physiological) continuous production of saliva which leads to:
(Pathological) obstruction of small intestine accompanied by (physiological) continuous production of saliva which leads to:
*Accumulation of fluid in stomach and small intestine cranial to obstruction
*Accumulation of fluid in stomach and small intestine cranial to obstruction
**note dilation of gut proximal to obstruction
**note dilation of gut proximal to obstruction
*Non-passage of the blockage leads to devitalisation and necrosis of intestine
*Non-passage of the blockage leads to devitalisation and necrosis of intestine
