Gastroenterology Surgery Procedures

Endoscopic Retrograde Cholangiopancreatography (ERCP):   This procedure uses a long, thin flexible tube with a camera and a torch attached to it called endoscope.  The endoscope is inserted via the mouth through the oesophagus into the stomach and duodenum (the initial portion of the small intestine).  Contrast dye is injected via the common bile duct once the endoscope nears the papilla (mouth of the common bile duct).  This procedure allows the doctor to take images.

Flexible Sigmoidoscopy:  This procedure allows the doctor to visualise the inside of the sigmoid colon. The colon, known as the large intestine, is the end portion of the gastrointestinal system. The part of the large intestine nearest to the rectum and anus is called the sigmoid. The sigmoid colon consists of 20 inches of the large intestine which is 4 feet long. The primary function of the large intestine is to store faeces till they are evacuated.

Colonoscopy : The colon or the large bowel is the end portion of the gastrointestinal system. Colonoscopy is done to visualise the colon using a colonoscope.  The scope is inserted and some amount of air is passed into the colon. The physician then takes images of the colon while steering the colonoscope throughout the colon.

Capsule Endoscopy : This procedure is done to visualise the small intestine. A tablet-sized capsule is swallowed which has its own source of light and camera. The video capsule sends images while going through the gastrointestinal tract. The images are sent to the waist belt worn by the patient that has a data recorder.

Liver Biopsy:  Liver biopsy is done to diagnose liver diseases such as liver inflammation, fibrosis, etc.

Endoscopic Ultrasonography (EUS): This diagnostic procedure is done to determine the extent of disease in the gastrointestinal tract. Gallbladder and pancreas are can also be investigated with the help of this procedure.

Double Balloon Enteroscopy:  This procedure is done to examine those parts of small bowel which are unreachable using other procedures.  A high-resolution endoscope is utilised which has latex balloons. These balloons which are positioned at the tips can be either deflated or inflated using a pressure controlled pump. Inflation and deflation cycles push the scope deeper into the small intestine. This procedure is helps in diagnosing Crohn’s disease, diarrhoea of unknown cause and gastrointestinal bleeding.

Upper Gastrointestinal Endoscopy:  This procedure is done to examine the stomach, duodenum and oesophagus.  This procedure is done to look for causes of abdominal or stomach pain, tumours, ulcers, bleeding, difficulty swallowing, heartburn, etc.
