Endterm Flashcards
Radiographic examination which includes the distal part of esophagus, stomach, duodenum and proximal part of jejunum with the use of barium sulfate.
UPPER GI SERIES
11 Indications for UGIS
Diverticulum, gastritis, gastric outlet obstruction, sol, abdominal new growth, peptic ulcer, duodenal atresia, hiatal hernia, tumor, polps, bezoar
Remember (UGIS)
Activities of the stomach, stomach habitus, regions of abdomen, quadrants of abdomen, stomach habitus, variation of stomach, and structures adjacent to stomach
3-6 inches inferiorly esp. distal and pyloric portion with pylorus moving as high a T12 and as low as the sacrum
Erect
Best depiction of relationship of stomach to the spine which measurements indicates the depth of retro-gastric space
Left lat erect
offer most superior displacement of stomach in this the gastric contents tends to flow into the fundus with some air within the stomach while fluid gravitates to the most dependent portion of the stomach. Best demonstrate the DCS of the body of stomach and pylorus.
Supine
greater tendency for a lower position of the stomach than in supine and to fall obliquely. Forward and downward. Barium tends to gravitates and fills up the distal end of the body of stomach, pylorus, bulb, and C-loop while there is usually mixtures of air and barium and BA. Coated mucosa of the fundus, thus DCS is achieved in the fundus
Prone
Llr swing backwards
Rlr
Dcs of body of stomach
Oblique/lao
Caused of barium retention in the stomach
Hypoacidity and emotional stress

2. Stomach-
- Rpo up.
- Rpo up, ap recumbent, lao recumbent, pa recumbent, spot fil 4:1 bulb
Ways of producing air in the stomach?
Two straw one outside one inside, breath thru his/her mouth of swallow air after ingestion of barium, Gas producing tablet- gastroluft, ez gas, ans alka seltzer, carbonated drinks
Pylorus and bulb for hypersthenic (45* cranially)
Gordon’s modification
Infants (35* cranially)
Gugliantini modification
Demonstrate a leaf like pattern of pylorus and bulb
Hamptons modification
Retro-gastric space to evaluate pancreatic mass
Popple’s method
35* hiatal hernia
Sommer-foegelle method
Rao
Wolf method
Roentologic investigation of biliary system of liver by means of functioning radiopaque cm
Cholangiography/cholecystography
Methods (cholangiography/cholecystography)
- Oral
- Iv
Indications (cholangiography/cholecystography)
- Determine function of liver, ability to remove cm from blood stream and excrete it with bile
- Determine patency of biliary ducts,
3.Conditions such as biliary calculi, papillomas,
4.Cholelithiasis
5.cholecystitis
6.neoplasm
7.biliary stenosis
8.congenital anomalies
Contra-indications (cholangiography/cholecystography)
- Advance hepato renal disease
- Active GI disease (V/D)
- Hypersensitivity to iodine
Modification for cholangiography/cholecystography
Trendelenburg maneuver
Fleischner modification
Post motor meal for cholangiography/cholecystography
1.Determine contracting and emptying power of GB
2. ap/pa (recumbent or upright)
functional study of biliary system
IVC
Indications for IVC
- Demonstrate biliary ducts of cholecystectomized subjects
- Investigate biliary ducts and gb of non-cholecystectomized subjects
- Incase of non-visualization of gb in oral method
- Incase of vomiting and diarrhea
- Physiology of GB
- Hepatoma
- Tumor
8 new growth
9 stones and biliary stenosis

60min- after meal
-same as oral chole
-px instructed to refrain from eating fatty foods for 4 days
-px may take 2 tabs of telepaque after each meal 4 days
Four day telepaque test
- Direct examination of biliary tract or pancreatic duct
- Non-functional study
- Invasive
- Oral/IV
- Px bring to RR
- Complication- PNM
Endoscopic retrograde cholangio-pancreatography
- Pre operative radiologic exploration of biliary tract
- Non-functional study/invasive method
Percutaneous transhepatic cholangiogram
Direct examination of GB and is done in operating room
Intraoperative cholangiogram
Indications for IOC
- Investigation of patency of bile duct and status of sphincter of ODDI
- Reveal presence of calculi that cannot be detected by palpation
3.demonstrate condition such as tumors, structures, or dilation of passage - Determine status of hepatopancreatic ampulla
Positioning for IOC
Ap,pa,rpo,lpo,ap fowlers and trendelenburg
Things to do in IOC
Necessary numbers of film and cassettes (with grid)- 10x12
Hangers and lead aprons goggles and thyroid shield
