ENDOSCOPY PROCEDURES · PATIENT EDUCATION
Gastroscopyexplained plainly.
Gastroscopy is a quick, sedated examination of the food pipe, stomach and duodenum with a thin flexible camera. It investigates acidity, ulcers, swallowing problems, bleeding and early cancer — and allows a biopsy to be taken in the same sitting.

What is a gastroscopy?
A gastroscopy (upper GI endoscopy) passes a slim flexible camera through the mouth to inspect the food pipe (esophagus), stomach and the first part of the small intestine (duodenum). It gives a direct, detailed view that scans cannot, making it the key test for upper-digestive symptoms.
What it detects & treats
Gastroscopy diagnoses reflux damage, hiatus hernia, gastritis, ulcers, H. pylori infection, narrowings and early cancers. It is also therapeutic — it can take biopsies, stop bleeding ulcers, remove small lesions and stretch narrowings, all without surgery.
What to expect
After a few hours of fasting, the procedure is performed under light sedation or with a numbing throat spray and usually takes 10–15 minutes. Most people go home the same day; if sedation is used, you will need someone to accompany you.

DOCUMENTED CASE · COLONOSCOPY & POLYPECTOMY
Polyp to Prevention: How a Colonoscopy Stopped a Cancer
1BEFORE TREATMENT
A patient in their 50s with a family history of colon cancer and subtle change in bowel habit, anxious about screening.
2TREATMENT
The polyp was lifted and excised endoscopically in full, with clear margins, during the same colonoscopy.
3AFTER TREATMENT
Pathology confirmed a pre-cancerous lesion removed completely — a cancer prevented. A surveillance schedule was set so any future polyps are caught equally early.
Outcomes vary between patients. These accounts describe individual experiences, not a guaranteed result.

10 / WHY DWARIKA HOSPITALABOUT THE HOSPITAL
Four promises.
One standard.
What every patient can expect here — from the first call to the last follow-up.
01.
Super-specialist led
Surgery here is performed by MCh-qualified surgical gastroenterologists, not general surgeons operating outside their specialty.
02.
Keyhole by default
Laparoscopic and scarless techniques are the standard approach, reserving open surgery for cases that genuinely need it.
03.
One team, one plan
Diagnosis, surgery, nutrition and follow-up sit under one roof — you are not handed between disconnected clinics.
04.
Counselling before consent
Every patient is told what the operation can and cannot achieve, with costs stated upfront, before anything is scheduled.
