Post-Hepatic Obstruction With Chronic Cholangitis In A 12-Year-Old FS Poodle Mix: Our Case Of the Month 2019
Pain, icterus, elevated total bilirubin and liver values - a bell goes off in every sonographer's head over this combo. Effectively imaging the portal hilus region- including the gallbladder, cystic duct, common bile duct, duodenal papilla, pancreas and pancreatic region- is essential and is exactly how Heidi Putnam, SDEP™ Certified Clinical Sonographer with Animal Sounds Northwest, handled the imaging of this case
The patient is under the diligent care of Dr. Bugarovich of VCA Westmoreland Animal Hospital. Patient is fairly stable on medical therapy post scan; surgery is still being considered an option if patient starts to decline.
Want to learn how to image the critical portal hilus as beautifully and throughly as this, so you can nail down a diagnosis? This view is SDEP Position 13, standard in the SDEP protocol and taught in our labs. For a list of our remaining 2019 labs, click here. Our 2020 lecture/lab dates will be available soon.
The patient was presented for painful abdomen, pyrexia, vomiting, and anorexia. After 12 hours on IVF and supportive care the patient's pyrexia resolved and there was no further vomiting. A painful abdomen persisted and mild icterus was evident in both the sclera and mucous membranes. The patient was treated with Cerenia, Unasyn, Metronidazole, Gabapentin, and Famotidine. Blood chemistry found AST 70, ALT 553, ALK. Phos. 8162, GGT 46, T. Bili. 7.2, K 3.4, Chol. 720, Trig. 609, amylase 2038, PSL 697. Urine specific gravity 1.011, proteinuria 2+, bilirubinuria 3+.
The liver revealed coarse architecture and increased portal markings. Gallbladder polyps and calculi were noted. The common bile duct was dilated to 0.6 cm. A shadowing structure was noted at the termination of the common bile duct with tissue thickening or mucoduct personation in the last 2.0 cm of the common bile duct prior to the duodenal papilla. The echotexture of the sludge and shadowing material in the common bile duct would be most consistent with calculus and concurrent thickening of the common bile duct with inflammation. Expansive masses were not present. Acoustic shadowing was noted. The calculus measured approximately 0.4 cm. Grouping of calculi measured approximately 1.0 cm.
