Primary Biliary Cholangitis (PBC) in St. Louis, MO
What is PBC (primary biliary cholangitis)? Primary biliary cholangitis (PBC), once known as primary biliary cirrhosis, is a rare chronic liver condition. PBC is a degenerative immune system condition that steadily damages the bile ducts (called the intrahepatic bile ducts) in your liver. Bile helps digest fats and transports away bad cholesterol, impurities, and bilirubin.

Friendly and accommodating staff. Very comfortable environment. Dr. Banerjee and staff are the best. Thank you.
No waiting to be seen. Pibi was prompt and thorough with the exam. Very pleased.
The procedure, the staff, and the facility are 5 stars.
The prep is horrible. While it worked well, the price is insane. $90 co pay. And to make it worse, the company has a coupon that EXCLUDES federal employees.
I will forgo colonoscopy for the rest of my life before I support that company

Excellent care and interaction with the staff and Dr Thyssen!
My complicated SIBO/SIFO situation was met with understanding and an ongoing search for treatment and hopeful resolution. It is a refreshing change from other doctors.
Dr. Weinstock has been such a blessing to me. He is ridiculously smart and caring. He is consistently open to learning and that makes him an excellent doctor. I am lucky to be his patient. His staff is helpful, professional and responsive.
I do recommend Dr. Leonard Weinstock, M.D. and the Advanced Endoscopy Center. From instructions beforehand to test results afterward, Dr. Weinstock and the staff took good care of me.
This group is incredibly compassionate and efficient. Everything flows like clockwork and at the same time they manage to be so comforting and communicative. Would recommend this practice to anyone needing this healthcare service.
