| Question | Answer |
|---|---|
| Radiographic and Fluoroscopic procedure of the Small Intestine, also referred to as a Small Bowel Series | SBFT - Small Bowel Follow Through |
| An SBFT is often performed in Combination with what? | UGI |
| What is the purpose of the exam? | To demonstrate radiographically the form and function of the Small Intestine and to detect abnormal anatomic and functional conditions |
| What type of exam is an SBFT? | A motility or timed exam - investigates how fast it takes contrast to travel through the entire Small Intestine |
| Clinical Indications for performing a SBFT: | Enteritis, regional Enteritis or Crohn's Disease, Giardiasis, Intrinsic or Extrinsic masses or tumors, Ileus, Sprue - Celiac Disease |
| Clinical Symptoms that the patient would be experiencing that would indicate the need to perform a SBFT: | Unexplained diarrhea (undiagnosed with a BE), Intestinal bleeding (positive stool test - blood in stool), changes in motility |
| Inflammation of the Small Intestine | Enteritis |
| What causes Enteritis? | Bacterial or Viral Infections |
| Radiographically, what happens when someone has inflammation of their Small Intestine? | The irritation of the Lumen of the Small Intestine can become thickened, irregular, and narrowed |
| A form of inflammatory bowel disease of unknown origin is known as? | Regional Enteritis/Segmental Enteritis - often referred to as Crohn's Disease |
| What part of the body is commonly involved when a person has Regional Enteritis or Crohn's Disease? | The Terminal Ileum of the Small Intestine |
| What can result in a Chronic Inflammatory Disorder? | The body's immune system attacks the GI Tract |
| What can Regional Enteritis or Crohn's Disease lead to? | Scarring (adhesions), thickening of the bowel wall, intestinal obstruction, fistula, and abscess formation |
| Two radiographic signs demonstrate the presence of Crohn's Disease: 1. 2. | 1. Cobblestone appearance of the intestine from scar tissue 2. String sign where segments of the intestine become narrowed due to chronic spasm |
| A common infection of the Lumen of the Small Intestine that is caused by a flagellate protozoan, often spread by contaminated food and water. | Giardiasis |
| How does it affect and what does Giardiasis affect? | It affects the Duodenum and Jejunum with spasms, irritability and increased secretions |
| How will a SBFT demonstrate Giardiasis? | As dilation of the Intestine, with thickening of the circular folds |
| How is Giardiasis confirmed? | By laboratory analysis of a stool specimen, |
| Malignant tumors found in the Small Intestine, particularly in the Duodenum and Proximal Jejunum. | Adenocarcinomas |
| Adenocarcinoma tumors of the Small Intestine produce what radiographically? | Short, napkin-ring defects within the lumen of the bowel |
| An obstruction of the Small Intestine | Ileus |
| What two types of bowel obstructions are there? | Mechanical and Adynamic |
| Types of mechanical bowel obstructions? | Volvulus or Adhesions which causes the Lumen of the bowel to stick together due to the Mucosal lining |
| Twisting of the Intestine | Volvulus |
| Scar Tissue | Adhesions |
| What type of bowel obstructions are due to loss of voluntary movement or lack of peristalsis (caused by medications, anesthesia, or disease process) which usually affects the entire GI Tract? | Adynamic |
| What is the radiographic appearance of a Small Bowel Obstruction or Ileus? | Dilated loops of small bowel that looks like stacks of coins on their side |
| A general term used to describe a variety of malabsorption syndromes in which the gastrointestinal tract is unable to process and absorb certain nutrients | Sprue |
| an autoimmune response to eating gluten, a protein found in wheat, barley and rye? | Celiac Disease |
| In whom does Celiac Disease usually occur? | Genetically predisposed people of all ages from middle infancy onward |
| Dependent on patient condition, what are the 4 different options available to visualize the Small Intestine radiographically? | 1. UGI with SBFT 2. SBFT only 3. Enteroclysis 4. Intubation SBFT |
| What procedure is performed to investigate the Stomach along with the Small Intestine? | UGI with SBFT |
| After UGI Overheads are performed, what does the patient do during a UGI with SBFT exam , and what is done following? | Drink an additional cup of Barium Sulfate and then images are taken at specific time intervals until the contrast medium passes into the Large Intestine |
| A procedure of the Small Intestine that begins with the patient drinking 2 cups of Barium Sulfate | Small Bowel Follow Through (SBFT) |
| When a patient is having a SBFT exam performed, after the patient drinks 2 cups of Barium Sulfate, when is overhead imaging performed? | At specific time intervals - routinely every 15-30 minutes during the first hour of the exam - after the first hour images are taken every half hour until Barium reaches the Large Intestine |
| During a SBFT procedure, what follows Overhead imaging when the Barium finally reaches the Large Intestine? | Fluoroscopic SPOT images are taken |
| A radiographic and Fluoroscopic procedure of the Small Intestine through an NG or feeding tube | An Enteroclysis |
| Tube placement for an Enteroclysis procedure? | Under Fluoroscopy, through the nose and passed to the junction of the Duodenum and Jejunum at the Angle of Treitz |
| How is contrast medium administered and why for an Enteroclysis? | By attaching a syringe to the NG or feeding tube and injecting it into the Small Intestine to dilate the loops of bowel, increasing mucusal lining visibility |
| A radiographic and fluoroscopic procedure of the Small Intestine through a specialized NG tube called a bilboa or Sellink tube | An Intubation SBFT |
| Where is the NG tube placed for an Intubation SBFT? | Into the Jejunum through the nose using Fluoroscopy |
| What type of Contrast Medium is used for an Intubation SBFT? | Water-Soluble Iodinated Contrast Medium |
| How is contrast medium administered in an Intubation SBFT? | By attaching a tube and injecting the contrast media into tubing |
| The Intubation SBFT can also be ______ if the patient has a known Small Bowel Obstruction | Therapeutic |
| Once tube placement has occurred during an Intubation SBFT, what is then done with the tube and for what reason? | The tube is then connected to a suction machine to remove gas and fluid to relieve distention of the bowel caused by a Small Bowel Obstruction |
| Type of contrast media used for a SBFT is dependent on patient condition and procedure to be performed, what are the options available when performing a SBFT? | Thin Barium or Water Soluble Iodinated Contrast medium |
| If the patient exhibits hypomotility of the Small Intestine, what can be done to promote the transit time of Barium (SBFT)? | Ice water may be provided to the patient |
| What is added to Barium to increase peristalsis and transit time of contrast media through the Small Intestine (SBFT)? | Water-Soluble Iodinated Contrast Medium |
| True or False? Oral Water-soluble iodinated contrast media travels faster through the GI tract than barium - which may affect the timing of Overhead Imaging if a UGI is ordered in conjunction with a SBFT or if only an SBFT is performed | True |
| Barium Sulfate is contraindicated under the following circumstances because it is not soluble and cannot be absorbed by the body: 1. 2. 3. | 1. Suspected GI or bowel perforation 2. Pre-surgery 3. Large Bowel Obstruction |
| In the even of contraindications to Barium Sulfate, what is used instead? | Oral Water-soluble Contrast Media |
| GI preparation prior to an SBFT may require the patient to be on a ____-______ diet ___ hours prior to exam | low-residue; 48 |
| GI preparation requirements prior to an SBFT exam? 1. 2. 3. 4. | 1. NPO after midnight of the day of the examination 2. Food and fluids wihtheld for at least 8 hours 3. No smoking or chewing gum during the NPO period |
| Why is there no smoking or gum chewing during the patient NPO period? | These activities tend to increase gastric secretions and salivation, which would prevent proper coating of barium to the gastric mucosa |
| Articles needed for an SBFT: 1. 2. 3. 4. | 1. 2-3 cups of Thin Barium (in conjunction with UGI, additional cup of Barium) 2. Emesis Basin 3. Protective lead apparel 4. 14x17 Image Receptors |
| What is commonly performed if a Small Bowel Follow Through exam is ordered without performing the UGI? | An AP SCOUT Projection |
| What Projections are taken of the Small Intestine are taken after the ingestion of barium in a timed sequence? | AP or PA Projections (Some Radiologists alternate) |
| When does the Fluoroscopic portion of an SBFT occur? | During the procedure if an area of interest is identified by radiologist on one of the Overhead images or at the end of the procedure |
| Why is the Fluoroscopic portion of the SBFT performed? | to demonstrate the Ileocecal Valve and to document that the entire length of the Small Intestine has been investigated |
