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.

With the plethora of subspecialties in medicine, patients frequently experience confusion about what type of doctor to visit for specific problems. As a gastroenterologist, I help patients with an array of conditions involving the gastrointestinal tract, including all of the organs in the digestive system. With such a wide scope, gastroenterologists provide care for common conditions such as acid reflux, ulcers, gallbladder disease, irritable bowel syndrome, nutrient malabsorption, and many others.
Gastroenterologists are medical doctors who have completed a four-year medical degree, a three-year internal medicine residency, and a gastroenterology fellowship. While learning diagnosis and treatment, gastroenterologists also receive training dedicated to endoscopy, which involves employing lighted tubes to see inside the intestinal tract.
Your general practitioner may refer you to a gastroenterologist, and in many cases, you may be able to self-refer as well. Nearly all people visit a gastroenterologist at some point in their lives because some of the critical functions doctors in this specialty perform include sigmoidoscopy and colonoscopy, which physicians recommend to detect colorectal cancer beginning at the age of 50.
