Here are the most reputed hospitals in India for Gastric Sleeve Revision Surgery. These hospitals are known for advanced infrastructure, international accreditations, and high success rates.
Gastric sleeve revision surgery is a second bariatric operation performed on patients who have previously had a sleeve gastrectomy and are experiencing inadequate weight loss, significant weight regain, or severe acid reflux. Because the original surgery permanently altered the stomach's anatomy, revision is more complex than the first procedure and requires careful evaluation to determine the best approach. The four main pathways are re-sleeve gastrectomy (trimming a stretched sleeve back to a narrower tube), conversion to Roux-en-Y gastric bypass (the most common choice when reflux dominates), conversion to duodenal switch with biliopancreatic diversion (for maximum weight loss in severe obesity), and conversion to SADI-S (a single-anastomosis variation of the duodenal switch). Most revision operations are performed laparoscopically under general anaesthesia and take two to four hours. Recovery is generally slower than after the original sleeve, with hospital stays of three to five days and a return to normal activities within four to six weeks.
The stretched remaining sleeve is trimmed and re-stapled into a narrower tube, restoring restriction without altering the intestinal route.
Estimated cost: ~$500 – $1,000
Typical tests for this variant: Upper GI endoscopy, Upper GI contrast swallow study or CT abdomen, CBC, LFT, KFT, Vitamin D, B12, folate, iron, calcium levels, HbA1c and fasting blood glucose, ECG. Done in India before hospital admission.
Estimated cost in India: $5,000 – $6,500
Pre-procedure stay (outside hospital): ~3 days
Hospitalisation: ~4 days
Recovery period (outside hospital): ~12 days recommended
Total stay: approx 19 days
The sleeve is converted into a small stomach pouch connected to the mid-small intestine, bypassing most of the stomach and providing strong reflux control alongside additional weight loss.
Estimated cost: ~$500 – $1,000
Typical tests for this variant: Upper GI endoscopy, Upper GI contrast swallow study or CT abdomen, CBC, LFT, KFT, Vitamin D, B12, folate, iron, calcium levels, HbA1c and fasting blood glucose, ECG, 2D Echocardiography (if indicated), PT/INR. Done in India before hospital admission.
Estimated cost in India: $5,500 – $8,000
Pre-procedure stay (outside hospital): ~3 days
Hospitalisation: ~5 days
Recovery period (outside hospital): ~14 days recommended
Total stay: approx 22 days
The sleeve is preserved and the duodenum is connected to a loop of lower small intestine in a single join, delivering strong metabolic effect with a simpler operation than the full duodenal switch.
Estimated cost: ~$500 – $1,000
Typical tests for this variant: Upper GI endoscopy, Upper GI contrast swallow study or CT abdomen, CBC, LFT, KFT, Vitamin D, B12, folate, iron, calcium, fat-soluble vitamins (A, E, K), HbA1c and fasting blood glucose, ECG, 2D Echocardiography (if indicated), PT/INR. Done in India before hospital admission.
Estimated cost in India: $7,000 – $9,000
Pre-procedure stay (outside hospital): ~3 days
Hospitalisation: ~5 days
Recovery period (outside hospital): ~15 days recommended
Total stay: approx 23 days
The sleeve stomach is kept and the small intestine is rearranged with two connections to maximise calorie malabsorption, offering the greatest long-term weight loss of all revision options.
Estimated cost: ~$500 – $1,000
Typical tests for this variant: Upper GI endoscopy, Upper GI contrast swallow study or CT abdomen, CBC, LFT, KFT, Vitamin D, B12, folate, iron, calcium, fat-soluble vitamins (A, E, K), zinc, HbA1c, fasting blood glucose, lipid panel, ECG, 2D Echocardiography, PT/INR, Pulmonary function test (if indicated). Done in India before hospital admission.
Estimated cost in India: $8,000 – $10,000
Pre-procedure stay (outside hospital): ~3 days
Hospitalisation: ~6 days
Recovery period (outside hospital): ~18 days recommended
Total stay: approx 27 days
