Canine gallbladder mucoceles and cholecystitis are common. Silent progression of gallbladder mucoceles often precede an emergent event where costly diagnostics, surgical intervention and post-operative critical care are required. While advancements in diagnostic imaging have led to earlier detection of a spectrum of gallbladder disease in dogs, many questions remain regarding causal aetiologies, diagnostic methodologies, the effectiveness of medical therapy, and when cholecystectomy is warranted.

This panel discussion connects a group of internationally renowned specialists in diagnostic imaging, internal medicine, and surgery to provide insight on canine gallbladder mucoceles and cholecystitis from three unique vantage points. We will discuss the relationship, if any, between these two diseases with special focus on current medical consensus and points of contention in the management of gallbladder mucoceles and cholecystitis in dogs. 

Abby graduated from Cambridge in 2001. After 5 years in busy first opinion small animal practice, she returned to Cambridge for a residency in Diagnostic Imaging, gaining the European Diploma in 2009. Since then she has worked as a specialist radiologist, currently combining specialist referral imaging at Dick White Referrals near Newmarket with teleradiology and research. She is a European and RCVS specialist in Veterinary Diagnostic Imaging, and became an RCVS fellow in 2022. 

She enjoys teaching and has trained number of imaging residents, and also enjoys helping general practitioners develop their imaging skills in particular teaching ultrasound and imaging of critical patients. She is currently an examiner for the ECVDI, and was previously Secretary of the European College, and Chair of the British and Irish Division of EAVDI. She has authored many papers and book chapters in the field of  veterinary diagnostic imaging. 

Dr. Johnston earned her B.S. in Microbiology and Veterinary Sciences from the University of Arizona and her D.V.M. from Tufts University School of Veterinary Medicine. She completed her residency in Small Animal Internal Medicine at Cornell and earned her Ph.D. in Molecular Biology from UT Southwestern in Dallas. Dr. Johnston is currently an assistant professor at LSU School of Veterinary Medicine, where she is investigating the role of mitochondrial membrane protein PGAM5 in hepatocellular carcinoma. Her clinical interests are canine and feline hepatobiliary disease.

Dr. Cynthia R. Leveille-Webster is a Professor and Associate Chair of Research at the Cummings School of Veterinary Medicine at Tufts University.

Dr. Webster is an expert in canine and feline liver disease and a board-certified small animal medicine internist. At the Cummings School, she leads the veterinary Liver Study Group, an umbrella organization of the Comparative Gastroenterology Society. Her research interests include how the liver regulates its ability to survive after toxic insults, especially during times when bile flow is attenuated.

Dr. Webster grew up in a small town in western Massachusetts. She says she was drawn to comparative medicine so that she could one day not only care for dogs and cats, but also solve problems in human medicine. After attending Cornell University’s veterinary school and doing post-graduate work in liver disease at Tufts University School of Medicine, Dr. Webster now has a joint appointment that allows her to do just that: she teaches gastrointestinal and liver pharmacology, pathology and medicine to DVM students at the Cummings School and lectures graduate students at Tufts Graduate School of Biomedical Sciences in Boston.

JP qualified in 1991 from the Veterinary School of Nantes, France. After few years in small animal practice in France, he went to perform a Small Animal Internship at Colorado State University, USA. Then, he worked in a small animal referral practice before entering a small animal surgery residency training program at the University of Bristol, United-Kingdom. He became a diplomate of the European College of Veterinary Surgeons in 2004. Following his residency he went back to Nantes to work as a small animal soft tissue surgeon in a referral practice. With other specialists he set up in 2006 a small animal referral hospital (CHVA) in Nantes, France. He is still working in the same hospital as a small animal soft tissue surgeon with a special interest in gastrointestinal, thoracic and minimally invasive surgery. JP was very active in his specialist college (ECVS) over the last 10 years. He lectures extensively at national and international courses/conferences on small animal surgery has published several papers in peer-reviewed veterinary journals and text books.
