Endoscopy is a nonsurgical procedure used to examine a person's digestive tract. Using an endoscope, a flexible tube with a light and camera attached to it, the doctor can view pictures of your digestive tract on a color TV monitor.
1. Upper GI endoscopy:
During an upper endoscopy, an endoscope is easily passed through the mouth and throat and into the esophagus, allowing the doctor to view the esophagus, stomach, and upper part of the small intestine. Patients are being advised to come nil per oral at 9.00 AM at endoscopy for the procedure. Total number of Upper GI endoscopy done in 2017-18 was 4432 and numbers have increased by more than 200% from 2008 to 2018.
2. Lower GI endoscopy:
During lower GI endoscopy (colonoscopy) endoscopes can be passed into the large intestine (colon) through the rectum to examine this area of the intestine. This procedure is called sigmoidoscopy or colonoscopy depending on how far up the colon is examined. Patients are advised to take polytheneglycolpeparation in water one day prior to procedure in a prescribed format to ensure the clear bowel prior to the procedure. Total number of Lower GI endoscopy done in 2017-18 was 182 and numbers have increased by more than 80% from 2008-2018.
3. Endoscopic Retrograde Cholangio-pancreaticography:
A special form of endoscopy called endoscopic retrograde cholangio-pancreaticography, or ERCP, allows to take pictures of the pancreatic duct andbiliary system. ERCP is also used for stent placement and biopsies. The patients are instructed to come nil per oral on the day of procedure with prescribed medications at ERCP Room No. 3, Ground Floor, Department of Radiology, PGI. The procedure is done under fluoroscopy (X-ray) and hence avoided in pregnant patients. Total number of ERCPs done in 2017-18 was 377 and numbers have increased by more than 66% from 2008-2018.
