Mini Gastric Bypass Surgery in Ahmedabad — Expert Bariatric Procedure & Results

Q: What is mini gastric bypass surgery?

Mini gastric bypass (MGB) is a simplified bariatric procedure that creates a small stomach pouch and connects it directly to the small intestine, bypassing a portion of the stomach and intestine for effective weight loss.

What is Mini Gastric Bypass Surgery?

Mini gastric bypass, also known as One Anastomosis Gastric Bypass (OAGB), is a simplified version of the traditional Roux-en-Y gastric bypass. This procedure creates a smaller stomach pouch and establishes a single connection (anastomosis) to the small intestine, bypassing a significant portion of the stomach and proximal small bowel.

The procedure works through two primary mechanisms:

Restrictive Component: Creates a small stomach pouch (30-50ml) limiting food intake
Malabsorptive Component: Bypasses 150-200cm of small intestine, reducing calorie and nutrient absorption
Hormonal Changes: Alters gut hormones (GLP-1, GIP) improving insulin sensitivity and satiety

💡 Key Advantage of Mini Gastric Bypass
The simplified technique with single anastomosis reduces operative time, complications, and provides comparable weight loss results to traditional gastric bypass with potentially fewer nutritional deficiencies.

Mini Gastric Bypass Candidacy Criteria

Primary Indications

BMI ≥40 kg/m² (severe obesity)
BMI ≥35 kg/m² with significant obesity-related comorbidities
Age 18-65 years (case-by-case evaluation beyond this range)
Failed conservative treatment for at least 6 months

Sleep Apnea	Strong	80-90% improvement
Dyslipidemia	Moderate	70-80% improvement
GERD	Moderate*	Variable (requires careful evaluation)
Fatty Liver Disease	Moderate	85-95% improvement

Mini Gastric Bypass Surgical Technique

Dr. Ruchir Bhavsar performs mini gastric bypass surgery using advanced laparoscopic and robotic techniques at Gastroplus Hospital, Ahmedabad. The choice between laparoscopic and robotic surgery depends on patient factors, surgeon preference, and complexity of the case.

Pre-operative Preparation

Comprehensive Evaluation (2-4 weeks before surgery)
- Complete blood count, comprehensive metabolic panel
- HbA1c, lipid profile, thyroid function tests
- Vitamin B12, folate, iron studies, vitamin D
- Upper GI endoscopy (to rule out H. pylori, ulcers)
- Chest X-ray, ECG, echocardiogram (if indicated)
- Psychological evaluation and nutritional counseling
Pre-operative Diet (2 weeks)
- Low-calorie diet (800-1000 kcal/day)
- High protein intake (60-80g/day)
- Liver size reduction for safer surgery
Medical Optimization
- Diabetes management (target HbA1c <8%)
- Blood pressure control
- Smoking cessation (minimum 6 weeks)
- Sleep apnea treatment optimization

Surgical Procedure Steps

Laparoscopic Mini Gastric Bypass

Patient Positioning & Port Placement
- Reverse Trendelenburg position (30-45 degrees)
- 5-6 port technique (5-12mm ports)
- CO₂ insufflation to 12-15 mmHg
Gastric Pouch Creation
- Mobilization of greater curvature
- Division starting 2-3cm from GE junction
- Creation of 30-50ml gastric pouch
- Use of linear stapler (blue/gold cartridges)
Biliopancreatic Limb Measurement
- Identification of ligament of Treitz
- Measurement of 150-200cm from DJ junction
- Marking the anastomotic site
Gastrojejunal Anastomosis
- Side-to-side or end-to-side configuration
- Hand-sewn or stapled technique
- Anastomotic diameter 1.5-2cm
- Reinforcement with interrupted sutures
Final Checks
- Leak test with methylene blue or air insufflation
- Hemostasis verification
- Positioning of drains (if indicated)
