NB: the time to development of reflux is proportional to the distance to the intestinal segment involved, (e.g. 4 hours with duodenal obstruction<ref>Puotunen-Reinert, A, Huskamp, B (1986) Experimental duodenal obstruction in the horse.

+NB: rupture of a stomach containing dry, fibrous material may produce a more insidious onset of clinical signs of peritonitis than rupture of a fluid distended viscus. This probably relates to the speed at which gastric contents are able to disperse around the peritoneum.(Proudman)
