Intro Dz Of Intestinal Tract

Question 1

What is the difference between vomiting and regurgitation? (Abdominal contractions, process, sphincters, bile, content, prodromal nausea, time after eating)

Answer 1

Vomiting: abdominal contractions, reverse peristalsis from stomach/duodenum, sphincters actively open/relax, can have bile, content is liquid, digested/U digested food, there is prodromal nausea and/or retching

Regurg: no abdominal contractions, backflow from esophagus or pharynx, no change in sphincters, no bile, contents are undigested food and or liquid/mucus, no prodromal nausea/retching

Time is variable for both

Question 2

Answer 2

Small bowel
(Normal to mild increase in frequency, increased volume, no urgency, no tenesmus, unlikely to have mucous in feces, no hematochezia, melena possible, steatorrhea with malabsorption)

Large bowel
(Marked increase in frequency, normal to mild increase in volume, urgency, tenesmus, mucous and hematochezia often, no melena or steatorrhea)
