Todd Huntley Baron is an American gastroenterologist who is Professor of Medicine at the University of North Carolina School of Medicine.Additionally, he currently serves as the Director of Advanced Therapeutic Endoscopy within UNC's Division of Gastroenterology and Hepatology. He is known for his publishing in the field of gastroenterology particularly in endoscopic retrograde cholangiopancreatography (ERCP), endoscopic ultrasound (EUS) and other advanced endoscopic procedures. He has developed interventional endoscopic techniques for the care of patients with gastrointestinal, liver and other medical conditions. He was the first to describe endoscopic drainage of the gallbladder, placement of a colonic stent, and endoscopic pancreatic necrosectomy.
Baron was born in Danbury, Connecticut in 1960, but was raised in South Florida from an early age. At the age of nine he entered competitive kart racing where he won numerous Florida State and Regional racing Championships and eventually won two International Kart Federation Grand National Championships.
Baron completed both his undergraduate and medical degrees from the University of Florida in Gainesville, Florida. He completed his internal medicine residency, chief residency and gastroenterology fellowship at the University of Alabama at Birmingham. He completed additional training at Duke University in ERCP before joining the faculty at the University of Alabama at Birmingham, where he founded the ERCP program. He was recruited to the Mayo Clinic in Rochester, Minnesota where he became the director of pancreaticobiliary endoscopy.In 2014 he joined the faculty at the University of North Carolina as a professor of medicine and director of advanced therapeutic endoscopy.
Gastroenterology is the branch of medicine focused on the digestive system and its disorders. The digestive system consists of the gastrointestinal tract, sometimes referred to as the GI tract, which includes the esophagus, stomach, small intestine and large intestine as well as the accessory organs of digestion which include the pancreas, gallbladder, and liver. The digestive system functions to move material through the GI tract via peristalsis, break down that material via digestion, absorb nutrients for use throughout the body, and remove waste from the body via defecation. Physicians who specialize in the medical specialty of gastroenterology are called gastroenterologists or sometimes GI doctors. Some of the most common conditions managed by gastroenterologists include gastroesophageal reflux disease, gastrointestinal bleeding, irritable bowel syndrome, inflammatory bowel disease (IBD) which includes Crohn's disease and ulcerative colitis, peptic ulcer disease, gallbladder and biliary tract disease, hepatitis, pancreatitis, colitis, colon polyps and cancer, nutritional problems, and many more.
Hepatology is the branch of medicine that incorporates the study of liver, gallbladder, biliary tree, and pancreas as well as management of their disorders. Although traditionally considered a sub-specialty of gastroenterology, rapid expansion has led in some countries to doctors specializing solely on this area, who are called hepatologists.
Cholecystectomy is the surgical removal of the gallbladder. Cholecystectomy is a common treatment of symptomatic gallstones and other gallbladder conditions. In 2011, cholecystectomy was the eighth most common operating room procedure performed in hospitals in the United States. Cholecystectomy can be performed either laparoscopically, or via an open surgical technique.
Endoscopic retrograde cholangiopancreatography (ERCP) is a technique that combines the use of endoscopy and fluoroscopy to diagnose and treat certain problems of the biliary or pancreatic ductal systems. It is primarily performed by highly skilled and specialty trained gastroenterologists. Through the endoscope, the physician can see the inside of the stomach and duodenum, and inject a contrast medium into the ducts in the biliary tree and pancreas so they can be seen on radiographs.
Gastrointestinal diseases refer to diseases involving the gastrointestinal tract, namely the esophagus, stomach, small intestine, large intestine and rectum, and the accessory organs of digestion, the liver, gallbladder, and pancreas.
Common bile duct stone, also known as choledocholithiasis, is the presence of gallstones in the common bile duct (CBD). This condition can cause jaundice and liver cell damage. Treatments include choledocholithotomy and endoscopic retrograde cholangiopancreatography (ERCP).
Magnetic resonance cholangiopancreatography (MRCP) is a medical imaging technique. It uses magnetic resonance imaging to visualize the biliary and pancreatic ducts non-invasively. This procedure can be used to determine whether gallstones are lodged in any of the ducts surrounding the gallbladder.
Double-balloon enteroscopy, also known as push-and-pull enteroscopy, is an endoscopic technique for visualization of the small bowel. It was developed by Hironori Yamamoto in 2001. It is novel in the field of diagnostic gastroenterology as it is the first endoscopic technique that allows for the entire gastrointestinal tract to be visualized in real time.
Ascending cholangitis, also known as acute cholangitis or simply cholangitis, is inflammation of the bile duct, usually caused by bacteria ascending from its junction with the duodenum. It tends to occur if the bile duct is already partially obstructed by gallstones.
Therapeutic endoscopy is the medical term for an endoscopic procedure during which treatment is carried out via the endoscope. This contrasts with diagnostic endoscopy, where the aim of the procedure is purely to visualize a part of the gastrointestinal, respiratory or urinary tract in order to aid diagnosis. In practice, a procedure which starts as a diagnostic endoscopy may become a therapeutic endoscopy depending on the findings, such as in cases of upper gastrointestinal bleeding, or the finding of polyps during colonoscopy.
Sphincter of Oddi dysfunction refers to a group of functional disorders leading to abdominal pain due to dysfunction of the Sphincter of Oddi: functional biliary sphincter of Oddi and functional pancreatic sphincter of Oddi disorder. The sphincter of Oddi is a sphincter muscle, a circular band of muscle at the bottom of the biliary tree which controls the flow of pancreatic juices and bile into the second part of the duodenum. The pathogenesis of this condition is recognized to encompass stenosis or dyskinesia of the sphincter of Oddi ; consequently the terms biliary dyskinesia, papillary stenosis, and postcholecystectomy syndrome have all been used to describe this condition. Both stenosis and dyskinesia can obstruct flow through the sphincter of Oddi and can therefore cause retention of bile in the biliary tree and pancreatic juice in the pancreatic duct.
Endoscopic stenting is a medical procedure by which a stent, a hollow device designed to prevent constriction or collapse of a tubular organ, is inserted by endoscopy. They are usually inserted when a disease process has led to narrowing or obstruction of the organ in question, such as the esophagus or the colon.
Peter B. Cotton is a British Gastroenterologist best known for his advancement in digestive disease, pioneering and naming the ERCP procedure and creating the Digestive Disease Center at the Medical University of South Carolina.
Cystogastrostomy is a surgery to create an opening between a pancreatic pseudocyst and the stomach when the cyst is in a suitable position to be drained into the stomach. This conserves pancreatic juices that would otherwise be lost. This surgery is performed by a pancreatic surgeon to avoid a life-threatening rupture of the pancreatic pseudocyst.
Amit Prabhakar Maydeo is an Indian gastroenterologist and endoscopy expert known for his pioneering efforts on therapeutic endoscopy and endoscopic retrograde cholangiopancreatography (ERCP). In 2013, he was honoured by the Government of India with the Padma Shri, the fourth highest civilian award, for his contributions to the fields of medicine and medical education. His son, Dr. Rohan Maydeo, is a surgeon from MGM Medical College and Hospital, Aurangabad.
Michel Kahaleh is an American gastroenterologist and an expert in therapeutic endoscopy.
Choledochoduodenostomy (CDD) is a surgical procedure to create an anastomosis, a surgical connection, between the common bile duct (CBD) and an alternative portion of the duodenum. In healthy individuals, the CBD meets the pancreatic duct at the ampulla of Vater, which drains via the major duodenal papilla to the second part of duodenum. In cases of benign conditions such as narrowing of the distal CBD or recurrent CBD stones, performing a CDD provides the diseased patient with CBD drainage and decompression. A side-to-side anastomosis is usually performed.
Nib Soehendra is a German surgeon known for numerous contributions to the field of endoscopy and therapeutic endoscopy.
Kenneth Frank Binmoeller is a medical doctor and author of multiple scientific contributions and over 300 publications, as well as the inventor of the lumen-apposing metal stent (LAMS) and AXIOS System. These are medical devices used to relieve blockages while creating a direct connection between two bodily structures. He practices in the field of Gastroenterology with a specialty of Advanced Endoscopic Intervention. Binmoeller has been published for his innovations in medical devices and training in the field of Endoscopy.
Biliary endoscopic sphincterotomy is a procedure where the sphincter of Oddi and the segment of the common bile duct where it enters the duodenum are cannulated and then cut with a sphincterotome, a device that includes a wire which cuts with an electric current (electrocautery).
