ba.meal final
DESCRIPTION
TRANSCRIPT
Barium meal is radiological study of esophagus, stomach, duodenum.
Done by oral administration of contrast media barium sulphate
Gastric or duodenal obstruction Malignancies of gastro esophageal
junction, stomach, duodenum Upper abdominal mass Motility disorders Systemic diseases like Tb Git hemorrhage
Epigastric pain suggestive of peptic ulceration
Anorexia Weight loss Vomiting Anemia Heart burn Dyspepsia
CAUSE OF VOMITING:
Gastro esophageal reflex Pyloric obstruction Mal rotation
1.Complete large bowel obstruction 2.Suspected perforation (unless water
soluble contrast medium used)PATIENT PREPARATION : 1. NPO after midnight(6 hrs) 2.abstain from-smoking, chewing gum or
antacids- ->dec fluid in stomach which impairs
barium coating.
1.Hypotonic agent Buscopan(hyoscine butyl bromide,20 mg i.v) or 0.1-0.2 mg i.v glucagon is injected intravenously -relax stomach and suspend peristalsis.
A packet of effervescent granules swallowed with small amount of water- releases CO2 and gastric distension.(approx 400ml CO2)
High density barium is swallowed(120 ml- 250% w/v) and double contrast views of oesophagus is obtained standing RAO.
Patient faces Xray table,lowered to horizontal
Then turned onto left side and finally supine.
Patient rolled from side to side so as
barium coats mucosal surfaces properly-washes over the mucus .

When barium enters duodenum, patient is turned RAO – fills duodenum with gas, DC films are taken.
Under fluoroscopic guidance, on the compression views-filling defects or abnormal collections are detected.
Note: young children- main indication identify cause of vomiting eg:-pyloric obstruction, malrotation,and GOR.single contrast technique preferred(30% w/v Barium sulfate with no paralytic agent).
Flow technique identifies-subtle mucosal abnormalities.
Note : kV range double contrast- 70-120 kV.
single contrast-120-150kV . Note: If partial gastrectomy or drainage
procedures (eg; pyloroplasty or gastrenterostomy), begin with prone swallow using high density barium. Reaching duodenum or Genterostomy-turned supine for DC films.DC of stomach and esophagus follows.
ADVANTAGES: Pylorospasm, Fistulae, Enlarged
Gastric Rugae Are Best Seen Filling Defect Due To Large Mass
Easily IdentifiableDISADVANTAGES: Lack of sensitivity of small erosion
linear ulceration sup gastric ca subtle mucosal abnormalities
ADVANTAGE: highly accurate detecting abnormalities
following gastric surgery, bile reflex gastritis, marginal ulceration, recurrent carcinomas
Abnormalities of efferent loopDISADVANTAGES: Misses some polyp, ulcers, erosion , sup
carcinoma

Surface: reticular pattern – multiple interconnecting grooves.
Divides- polygonal islands(2-4 mm)areae gastricae.distal 2/3rds.
Presence- excludes diffuse atrophic gastritis
>4mm sign of gastritis Fundus and body.- longitudinal folds or
rugae.
Duodenum- Extends from pylorus to duodenojejunal
flexure-cap,second part(descending horizontal,third part(ascending) and fourth part.
Barium meal-cap-fine velvety reticular surface pattern by villi.
Barium caught under mucosal pattern – incomplete erosive duodenitis
Barium caught underfold between 1st and 2 nd part of duodenum-ulcer pic
Beyond cap-mucosal folds-narrow bands across whole width.
Major papilla of Vater(2ND PART) Central fold and 2 oblique folds Minor papilla(Santorini- 2 CM PROXIMAL)
Frail and immobile, modification. Single contrast examination: 100%w/v barium – oesophagus, stomach
and duodenum Compression applied-lower stomach and
duodenum. Approximates front and back walls with thin layer in between.
Protruding lesion-radiolucent filling defect Depressed-eg:ulcer --focal extra density.

COMPLICATION; Peritonitis Aspiration pneumonia Impaction,-convert partial obstruction
into complete obstruction Gastric dilatation Barium embolisation if bleeding ulcer is
present
BENIGN MALIGNANTRound to oval punched out lesion with straight walls &
flat smooth base
Irregular outline with necrotic or hemorrhagic
base
Smooth margins with normal surrounding
mucosa
Irregular & raised margins
Mostly on lesser curvature Anywhere
Majority<2cm Any size
Normal adjoining rugal folds that extend to the
margins of the base
Prominent & edematous rugal folds that usually do not extend to the margins
X-ray showing Gastric ulcer With symmetrical radiating
Mucosal folds.By histology, no evidence of Malignancies was observed.
X-ray showing Extensive carcinoma involving the cardia & Fundus
Pyloric stenosis
