Many conditions in the esophagus, stomach and colon are diagnosed and treated through endoscopy by general gastroenterologists. Complex interventional endoscopy offers effective options for diagnosis and treatment of more complex conditions in these parts of the body, but also in the deep small intestine and other digestive organs, such as the liver and pancreas. Utilizing cutting-edge multimodality imaging and therapeutic technologies, the Paul May and Frank Stein Interventional Endoscopy Center at CPMC in San Francisco is able to diagnose and treat a wide variety of complex diseases and conditions including:

• Barrett's esophagus
• Early stage cancers
• Obstructive cancers
• Benign stricture
• Bile and pancreatic cancer
• Bile and pancreatic stones
• Variceal bleeding
• Non-variceal bleeding
• Fistulas and leaks
• Zenker's diverticulum
• Obesity and diabetes
• GERD
• Achalasia
• Large polyps
• Submucosal tumors
• Pseudocysts, walled off necroses (WON)
• Acute cholecystitis and gallstones
• Gastric outlet obstruction

Pioneering Procedures

Our world-class interventional endoscopy subspecialists at the Paul May and Frank Stein Interventional Endoscopy Center at CPMC are researching and developing new advanced procedures and devices for non-surgical treatment of these conditions as well as others. An example is the lumen-apposing metal stent (LAMS), invented by Dr. Kenneth Binmoeller, which is used to relieve blockages of various causes and create a direct connection (“bypass”)  between neighboring structures like the gallbladder and bowel. Through the Interventional Endoscopy Center, the most cutting-edge, state-of-the-art advanced endoscopic options are offered.
