LAP-BAND TO GASTRIC BYPASS (RNY OR MINI)

Service Description

A Lap-Band to Gastric Bypass revision—either Roux-en-Y (RYGB) or Mini Gastric Bypass (MGB/OAGB)—is a common and highly effective revisional bariatric surgery for patients who experienced complications or failure after adjustable gastric banding. 🔄 Lap-Band to Gastric Bypass Revision A Powerful Conversion for Improved Weight Loss and Symptom Resolution 🩺 What Is It? This revision involves removal of the gastric band, followed by either: Roux-en-Y Gastric Bypass (RYGB) – the gold standard for bypass surgeries, using two anastomoses to create a small pouch and bypass part of the small intestine Mini Gastric Bypass (MGB/OAGB) – a simplified alternative that uses a single gastrojejunal anastomosis to achieve both restriction and malabsorption 🧬 Why Convert a Band to a Bypass? Lap-Band complications or failure are common long-term: Reason for Conversion and Description 🛑 Band intolerance: Nausea, vomiting, dysphagia, pain 🔁 Weight regain or failure: Insufficient weight loss 🔧 Mechanical issues: Slippage, erosion, port infection 🌡️ GERD or esophagitis: Band pressure on LES leads to reflux 💊 Need for stronger metabolic control: Especially for diabetes or insulin resistance ✅ Benefits of Band to Bypass Revision ✔️ Removes foreign body (the band) ✔️ Improves or resolves reflux and esophageal problems ✔️ Offers strong weight loss and diabetes remission ✔️ Better long-term satisfaction and durability ✔️ Can be done in one stage (band removal + bypass) or two stages if there's severe inflammation Risks and Considerations - Adhesions and scar tissue: May increase technical difficulty - Leak risk: Slightly higher in revisions than in primary surgery - Deficiency risks: Must monitor B12, iron, calcium, etc. - Longer recovery: Especially if done as a two-stage revision Outcomes - % Excess Weight Loss: 65–85% depending on procedure and patient adherence - GERD Resolution: 80–95% (RYGB best) - Diabetes Remission: 60–80% = Complication Rate: 5–12% (higher than primary bypass, but acceptable) 🧠 Summary - Converting a Lap-Band to RYGB is ideal when reflux or metabolic issues are present. - Converting to MGB is a simpler, faster alternative when GERD is not an issue. - Both offer substantial improvements in weight loss, comorbidity resolution, and quality of life.
