Upper GI Endoscopy (Gastroscopy)
Upper GI endoscopy, also known as gastroscopy, allows
Dr. (Brig) Pankaj Puri to examine the food pipe (esophagus),
stomach, and the first part of the small intestine (duodenum) when digestive
symptoms do not improve with medication alone. The procedure is performed at
Fortis Escorts Liver & Digestive Diseases Institute, Okhla Road,
providing advanced diagnostic and therapeutic care for patients across South Delhi.
During the procedure, a thin, flexible tube with a camera and light is gently
passed through the mouth into the upper digestive tract. This enables Dr. Puri
to examine the lining of the esophagus, stomach, and duodenum in real time,
identify abnormalities, take small tissue samples (biopsies) when required,
and perform treatments such as controlling bleeding or removing small polyps
during the same procedure.
Upper GI endoscopy is a safe day-care procedure that is usually performed with
mild sedation or a numbing throat spray. The examination generally takes
10–15 minutes, and most patients can return home the same day.
