muscularis propria
subserosa
serosa
where is the esophagus on ultrasound
posterior to left lobe of the thyroid
location of gastroesophageal junction on ultrasound
between left lobe and aorta
2 openings of the stomach
cardiac and pyloric
2 curvatures of the stomach
lesser and greater
2 surfaces of the stomach
anterior and posterior
parts of the stomach
-fundus
-body
-pyloric antrum
-pylorus
folds of the stomach are called
rugae
3 parts of the small intestine
-duodenum
-jejunum
-ileum
ileo-cecal orifice
markes the entry into large intestine
landmark to find appendix
large intestine divides into
appendix
cecum
ascending, transverse, descending colon
rectum
normal wall thickness in distended bowel
3mm
normal wall thickness in non distended bowel
5mm
“keyboard sign”
tubular structure
mixture of fluid
small bowel obstruction
gut signature
target sign
peristalsis
contractions which move food along digestive tract
duplication cyst
malformation of GI tract
more common in small intestine,ILEUM
duplication cyst on ultrasound
anechoic w/ thin echogenic rim (mucosa)
outer hypoechoic rim (muscle)
polyp
solid mass adherent to gastric wall
leiomyoma
most common tumor of the stomach
assoc w/ gall stones, peptic ulcer
gastric carcinoma
half occur in the pylorus
lesion may be ulcerated, diffuse, polypod, superficial
gastric carcinoma ultrasound
target or pseudokidney sign
appendicitis symptoms
sudden pain in RLQ
nausea vomiting
fever
appendicitis on ultrasound
target lesion
noncompressible
fluid and abscess
diameter >6mmm
wall thickness >3mm
increased vasculature
perforation
loculated pericecal fluid
crohns disease
recurrent inflammatory disease
involves entire thickness of bowel wall
crohns disease symptoms
diarrhea
fever
RLQ pain
intussusception
when one portion of bowel slides into the next like a telescope
creates blockage, swelling, inflammation, decreased blood flow
intussusceptions occurs most in….
most often in babies between 5 - 10 months
more common in boys
pyloric stenosis
narrowing of pylorus
most common cause of intestinal obstruction during infancy
pyloric stenosis symptoms
sudden vomiting
weight loss
dehydration
palpable abd mass
