Gastrointestinal Flashcards
(134 cards)
Bechet syndrome triad
Recurrent oral aphous ulcers
Genital Ulcers
Uveitis
Aphthous ulcer suggest presence of?
Inflammatory bowel diseases, Bechet syndrome
2 precursor lesions of sq cell carcinoma of mouth
Leukoplakia
Erythroplakia and Hairy
How to differentiate Leukoplakia, thrush and hairy leukoplakia
Leukoplakia cannot be scraped away (thrush can)
Hairy leukoplakia is on LATERAL tongue and is hairy looking (think HIV and EBV)
3 organs affected by mumps
Bilateral parotids
Orchitis
Pancreatitis
Think Amylase for diagnosis
Pleomorphic adenoma components
Stroma (cartilage!) and epithelial tissue –> BIPHASIC
Cystic parotid tumor with lymphoid tissue and germinal centers in the parotid
Warthin tumor (recall smoking and men)
TE fistula presentation (4)
Vomiting and coughing with FIRST FEEDING
Abdominal distension
Polyhydramnios
Esophageal web presentation and complication
dysphagia for solid, SCCA
Zenker diverticulum layers
Mucosa and submucosa only (false diverticlum)
Zenker location, the mechanism
b/w upper esophageal sphincter and pharynx, motor dysfunction*
Painful hematemesis in bullemic or alcoholic/retching
Mallory Weiss
Mallory weiss defect
longitudinal of mucosa at Gastroesophageal junction
Acute pain, X Ray haziness in mediastinum w/ shoulder pain, no hematemesis, Cardiac enzymes- normal
Borhaave syndrome –> ruputred GE junction
Usually Painless and Massive hematemesis of venous blood
Ruptured esophageal varicies
Dysphagia for solids + liquids with halitosis
Achalasia
Achalasia underlying defect
No ganglion cells in myenteric plexus = no relaxation
Imaging findings in Achalasia
Dilated esophagus
Increased LES pressure
Infectious cause of achalasia
Trypanasoma cruzi
Hiatal hernia- Sliding- complications?
Cardia of stomach herniates into esophagus–> GERD
“bowel sounds in the lung fields” is characteristic of
Hiatal hernia
late complication of GERD
Ulceration w/ stricture or adenocarcinoma
specific cell changes that occur in Barrets Esophagus
Non Keratinized Stratified Squamous epithelium –> Non ciliated columnar epithelium w/ goblet cells
Adenocarcinoma of esophagus location
