GIST
explained plainly.
Written for patients, reviewed by the surgeons who perform this treatment.
GISTs are rare tumours that grow in the wall of the digestive tract, most often the stomach. They are treated by precise surgical removal — frequently by laparoscopic surgery — and, when needed, highly effective targeted (oral) therapy.
- DEFINITION
- Tumour arising in the wall of the GI tract
- COMMON SITE
- Most often the stomach, then the small intestine
- WHEN TO SEE A SURGEON
- A submucosal mass found on endoscopy, bleeding, or a known GIST
- CURATIVE OPTION
- Surgical removal (often laparoscopic) ± targeted therapy
What is a GIST?
A gastrointestinal stromal tumour (GIST) arises from specialised pacemaker cells in the wall of the digestive tract. Unlike common cancers that start in the lining, GISTs grow within the wall itself. Most occur in the stomach, and they range from small, incidental lesions to larger tumours that need treatment.
Symptoms & diagnosis
Small GISTs are often found by chance during endoscopy for another reason. Larger ones can cause bleeding (sometimes seen as anaemia or black stools), vague abdominal discomfort or a feeling of fullness. Diagnosis uses gastroscopy, endoscopic ultrasound (EUS) with biopsy, and CT for staging.
Treatment options
The main treatment for a localised GIST is precise surgical removal with a clear margin, frequently achievable by laparoscopic surgery for tumours in suitable locations. For larger, higher-risk or advanced GISTs, targeted oral therapy (tyrosine-kinase inhibitors) is remarkably effective and may be used before or after surgery.
Why precise surgery matters
GISTs should be removed intact with a clear margin while avoiding rupture, as careful technique strongly influences outcome. Combining experienced surgery with modern targeted therapy gives excellent long-term results.

08 / 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.
