Ulcerative Colitis – Faulty Immune Response Cited as Possible Cause

Based in Torrance, California, Robert M. Webman, MD, is a gastroenterologist with extensive experience in gastrointestinal (GI) endoscopic procedures. One common GI problem that Dr. Robert Webman treats is ulcerative colitis.

Estimated to affect 700,000 Americans, ulcerative colitis is a chronic disease of the colon (large intestine) that typically affects people in their mid-30s and older.

Ulcerative colitis occurs when the colon’s lining becomes inflamed and affected by ulcers, or open sores. The result is cramp-like abdominal discomfort and a colon that empties with increased frequency and urgency. Typical symptoms include diarrhea and bloody stool. In addition, people may experience fatigue and reduced energy, as well as loss of appetite and weight loss. These symptoms are often periodic in nature, and many patients experience periods of months or years with no distress.

Researchers believe that ulcerative colitis is related to the complex interactions between the immune system and bacterial and viral infections affecting the colon. In particular, the immune system mistakes normal bacteria and food in the system as invading substances and generates excess white blood cells that ultimately cause ulceration.

Dr. Robert M. Webman – The Utilization of ERCP with Sphincterotomy

Dr. Robert M. Webman is a veteran southern California gastroenterologist who provides care in both private practice and hospital settings. Robert M. Webman, MD’s experience includes upper gastrointestinal treatments, such as endoscopic retrograde cholangiopancreatography (ERCP) with sphincterotomy.

Undertaken with radiography, the ERCP scope provides an accurate visualization of the pancreatic and bile ducts, which drain the pancreas and the liver. Primarily a therapeutic procedure, ERCP can be used to treat conditions such as chronic pancreatitis by removing painful duct stones. It is also employed in the removal of bile, stricture dilation, and in stent placement.

Sphincterotomy involves using a specialized catheter device to cut the muscle of the papilla, or the duct opening. The ERCP scope is vital in viewing this extremely small cut, which enables a number of duct treatments to proceed. In cases where bile duct stones need to be removed, the sphincterotomy enlarges the papilla to a point where the stones can be pulled into the bowel and removed. In cases of very large stones, they may need to be crushed into fragments within the duct, prior to removal.
