Mini Gastric Bypass Surgery | Pristyn Care

Risk Factors

Candidacy risk factors include:

• BMI above 35 with obesity-related comorbidities
• Failed conservative weight management programmes
• Poorly controlled type 2 diabetes or metabolic syndrome
• Severe obstructive sleep apnoea
• Significant cardiovascular or hepatic comorbidity
• Age 18-65 (selected cases outside this range)

Who Is a Candidate

Patients with BMI above 35 and obesity-related conditions, or BMI above 40, who have failed diet and exercise programmes are ideal candidates. Those with type 2 diabetes benefit particularly from the strong metabolic effect of mini gastric bypass.

Diagnosis

Pre-operative workup includes:

• Upper GI endoscopy to exclude Helicobacter pylori and significant GERD
• Blood tests: full blood count, HbA1c, lipid profile, liver function tests
• Ultrasound abdomen for gallstones
• Pulmonary function tests and sleep study if indicated
• Cardiac evaluation for high-risk patients
• Psychological and dietary assessment by specialist team

Treatment: Mini Gastric Bypass

Pristyn Care performs laparoscopic mini gastric bypass using a standardised technique with a 150-200 cm biliopancreatic limb, achieving excellent weight loss and metabolic outcomes with 2-3 day hospital stay.

Mini Gastric Bypass Procedure

Surgical procedure involves:

• General anaesthesia with 4-5 laparoscopic ports
• Creation of a long narrow gastric tube along the lesser curvature
• Measurement of 150-200 cm from Treitz ligament for biliopancreatic limb
• Single loop antecolic gastrojejunostomy
• Leak test with methylene blue or air insufflation
• Drain placement and port-site closure
• Total operative time approximately 60-90 minutes

After the Surgery

Post-operative care includes:

• Clear liquids day 1, pureed food at 2-3 weeks, soft diet at 6 weeks
• Lifelong daily multivitamins, B12, iron, and calcium supplements
• Avoidance of NSAIDs and alcohol
• Follow-up at 1, 3, 6 months and annually thereafter
• HbA1c and metabolic monitoring for diabetic patients
• Exercise programme introduced from 4-6 weeks post-op

Possible Complications of Mini Gastric Bypass

Potential complications include:

• Anastomotic leak at gastrojejunostomy
• Bile reflux into the gastric tube (managed with revision if persistent)
• Marginal ulceration
• Nutritional deficiencies (B12, iron, calcium, vitamin D)
• Dumping syndrome (early and late)
• Internal hernia (less common than in Roux-en-Y gastric bypass)
• Anastomotic stricture requiring endoscopic dilation
