MC benign gastric tumor
Dilated appendix filled with mucous.
Regional enteritis. Peristalsis absent or sluggish.
Digestive tract / Alimentary tract
Mouth, pharynx, esophagus, stomach, small intestine, large intestine.
Salivary glands, liver, pancreas
Secrete digestive juice into digestive system
Gastrin (via stomach)
Cholecystokinin (via fat in intestines, contracts GB)
Secretin: (via sm bowel to release bicarbonate to dec acid)
5 gut layers. Max diam 3 mm when distended, 5 mm when not.
Walled off gut during embryologic development.
Masses of congealed ingested foreign materials such as hair, veggie matter, inorganic matter. (Sand)
Not dx by US, older males, 1/2 in pylorus
Target, pseudokidney sign
Assoc with obstruction of appendicial lumen leading to inflammation
MC cause of childhood ab pain. 4-15 yrs. >200,000 cases/yr in US.
Fever, periumbilical pain, inc wbc, nausea, vomit due to pain, point tenderness RLQ
Noncompressible, inc color flow "ring of fire", "thyroid in the belly sign", hypo thick wall, periappendicieal fluid collection, appendicolith. Diam > 6mm, wall thick > 2mm
Tx: laparoscopy (small incision) or laparotomy (large)
Mc Burney's sign. Pain when pressure release RLQ
Normal appendix sausage shape diam < 6mm and no Doppler flow.
Bacterial infection leads to gangrene and perforation
Appendix > 6mm or an appendicolith is highly suggestive of appendicitis
Mc Burney's Point
1/3 from ASIS to umbilicus is location of appendix
Hypertrophic Pyloric Stenosis
Narrowing of the pylorus
Pylorus = channel between stomach and duodenum. It becomes thick due to contractility defect.
Projectile vomiting in neonates, palp olive shape mass

Usually 2-6wks (17 mm, muscle thickness >3.5 mm, AP diam >10 mm
X-ray shows string sign.
Tx: pyloromyotomy, Ramsteadt

90% ileocolic, males
6mn-2yrs, colicky ab pain, abd distention, vomit, abd mass, rectal bleed
Dark red jelly stool
LLQ pain, fever, leukocytosis
Thickened bowel, abscess in LLQ highly suggests diverticulitis
Congenital duodenal obstruction
Double bubble sign
Fluid filled duodenum and stomach separated by pylorus
Dec artery supply to intestinal system
