ENDOSCOPY PROCEDURES · PATIENT EDUCATION
Colonoscopyexplained plainly.
Colonoscopy is an endoscopic examination of the large intestine using a thin flexible camera. It diagnoses bleeding, polyps and cancer, and can remove polyps in the same sitting — preventing colon cancer before it starts.

What is a colonoscopy?
A colonoscopy uses a slim flexible tube with a camera to examine the entire large intestine. It is the gold-standard test for colon cancer screening and for investigating bleeding or a change in bowel habits.
What it detects & treats
Colonoscopy finds polyps, inflammation, diverticular disease and cancers. Crucially, polyps can be removed during the same procedure (polypectomy), preventing them from becoming cancer.
What to expect
After a bowel-cleansing preparation, the procedure is performed under sedation and takes about 20–30 minutes. Most people return home the same day and resume normal activity quickly.

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.
“A colonoscopy caught a polyp early. Calm, reassuring and thorough — I am grateful for the careful approach.”
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.
