GI/Nutritional Flashcards
What separated upper GI bleed from lower GI bleed
ligament of treitz
Signs of UGI bleed
hematemesis and melena
Signs of LGI bleed
hematachezia (bright red blood per rectum)
can also be melena
Cullen Signs
umbilical ecchymosis
Grey Turner
flank ecchymosis
Pancreatitis tx
Supportive → IVF, Bowel rest (NPO) & Pain meds → Meperidine (Demerol), Morphine
Gallstone pancreatitis → cholecystectomy (after recovery from pancreatitis)
Fever, leukocytosis several days/not improving → CT w/ contrast look for necrosis
Severe, necrotizing, cholangitis → broad spectrum ABX (Imipenem)
Biliary sepsis, obstructive jaundice → ERCP
Calcifications + Steatorrhea + DM
Triad of chronic pancreatits
calcified pancreas
chronic pancreaitis
define Cholelithaisis
Gallstones in gallbladder or bile duct (NO INFLAMMATION)
EPISODIC, abrupt RUQ ↑↓ pain that lasts 30 min - 1hr a/w nausea
Precipitated by a fatty/large meals
Cholelithaisis
Cholelithaisis tx
Asx → Observation, Ursodeoxycholic acid (dissolve small stones, prevent formation)
Sxs → Cholecystectomy
define Cholecystitis
Gallstone in cystic duct → obstruction → inflam/infxn
CONSTANT & severe RUQ pain → shoulder (Boas sign - phrenic nerve irritation)
Cholecystitis
Cholecystitis tx
NPO + IVF + ABXs (Ceftriaxone + Metro) + Pain meds → Cholecystectomy
Cholangitis Gold stand dx
Cholangiography via ERCP
Charcot’s Triad
Fever + RUQ pain + Jaundice
For Cholangitis
Reynolds Pentad
Charcot’s + Sepsis + AMS
For Cholangitis
For Cholangitis tx
ABXs
ToC =ERCP (Endoscopic Retrograde CholangioPancreatography) aka sphincterotomy
Decompress CBD/stone extraction
Cant do ERCP → PTC (Percutaneous Transhepatic Cholangiography)
MCC exophageal ca

GERD/Barrett’s esophagea ca type + location
lower 1/2 (adenocarcinoma)
long bird’s beak w/irreg narrowing
Esophageal Cancer
Esophageal Cancer tx
Surg (Esophag resection) = only cure (Most die w/in 5 yrs, 5 yr survival rate = 5-10%)
Radiation/chemo
“Bird’s Beak esophagus”*
Achalasia
Achalasia tx
↓ LES pressure → Botox inj, Nitrates, CCBs
Disrupt LES w/
Endoscopic Pneumatic Dilation (inflate balloon, break esophageal muscle w/out perforating esophagus)
Surg (Esophageal Myomectomy) - complic = GERD
Achalasia GS dx
Esophageal Manometry**→ ↑ LES pressure, ↓ peristalsis
Pressing on neck facilitates food passage
Halitosis (retained food)
Sense of lump in neck/neck mass
Zenker’s Diverticulum
Zenker’s Diverticulum dx
Barium Esophagram
Ring of mucosal tissue in distal esophagus
Schatzki’s Ring
Schatzki’s Ring dx
Barium swallow/esophagram → notches
Schatzki’s Ring tx
NO Reflux → disrupt ring w/ Endoscopic dilation
Reflux → Antireflux surg
