Discussion
Ultrasonography was performed with a linear transducer in supine position. On transverse image the pylorus was identified to the left of gallbladder. The typical ‘target sign’ or ‘doughnut sign’ was seen due to thickened pyloric muscle. On the longitudinal image the pylorus was elongated. The pyloric canal length measured 18 mm. The pyloric muscle thickness measured 4.6 mm and the pyloric diameter measured 14mm. The stomach was distended and there was failure of the pyloric canal to open during the scan.

The diagnostic accuracy of ultrasonography for hypertrophic stenosis is high. The sensitivity and specificity approach 100 % [1] and ultrasonography is now the procedure of choice for the detection of pyloric stenosis.

CRITERIA FOR DIAGNOSIS[2]:
Muscle thickness >- 3mm.
Pyloric canal length >- 1.2 cm.
No peristalsis through pylorus.

Other important features to look for are the double mucosal canal of pylorus, excessive antral peristalsis, delayed or absent passage of fluid into the duodenum. It is important to note these additional features, as pylorospasm may mimic hypertrophic pyloric stenosis and to avoid false –positive diagnosis[3].

Pylorospam is a condition which is typically transient.

VIABLE
ABDOMINAL
ULTRASOUND

the external liver surface should be be smooth & linear
Liver cirrhosis is suspected when surface is irregular or rough

The portal vein branches to Rt & Lt portal veins at the hilum
The Rt P. brabnch wall should be bright & well visualized without tortousness. The inner aspect should be seen as lumina structure without echogenicity

The diaphragm is a firm fibro tic tissue seen as hyper echoing smooth line.
It is a landmark showing the size of the Rt liver lobe at a glance
Every continuity should be seen in a plane in normal case ...but when Rt lobe is enlarged, it displaces the diaphragm to the posterior & makes diaphragm invisible...

The inferior vena cava

This structure located Rt lateral
side between posterior of the liver & anterior of vertebra
It leads to the Rt atrium

Para umbilical vein & collateral veins are originated at the umbilical portion of the left portal vein branch

Liver parenchymal tissue

It constitutes of fine & homogeneous liver parenchymal
There is neither loss or enhance of echogenecity
Intrahepatic bile duct should not be seen
To scan around PV : view point at 8 0,clock position :: let pt bulge his abdomen vigorously with probe heading to Cephalon direction

To scan around the HV
view point at 8-9 O'clock position
Let pt make baden flaccid & scan with probe firmly pressing
heading to Cephalon direction abdomen obliquely
Find out 3 linear vessels which drain into IVC


To scan PV & CBD
view point at 9-10 O'clock position
Let pt bulge out abdomen slightly & scan with pushing probe roads abdomen

The main PV is formed by the superior & inferior mesenteric
veins and the splenic vein
It carries blood (75% of liver blood flow )from git..GB.. pancreas..& spleen to liver

Normal PV dieter is less than 1.5 cm from inner to inner walls

During hepatic scanning
..Size.parenchym echo. ..P.texture surface or margin. . SO. . PV or HV dilatation.. lntrahep.duct dilatation ..lntrahep or lntraductal stone ..fluid

CBD
Normal diameter less than 7 mm
It locates in front ie anterior to PV
when CBD dilated will be larger than PV diameter

GB
scan method best visualizing bile duct between GB & CBD

MPV dipper looks Red as it drains obliquely upward to the probe
