Mini-gastric bypass.
A mini gastric bypass surgery functions just like a traditional gastric bypass surgery bun that the stomach is divided into upper and lower pouches and the small intestine is rerouted. This allows for both restrictive and malabsorption weight loss.
The primary difference between mini gastric bypass surgery and a full gastric bypass is that the mini version of the surgery is performed in a modified manner that involves less intestinal rerouting and a shorter overall surgery time.
The mini-gastric bypass was developed to reduce operating time, simplify the procedure and reduce complications. Recent studies show that it does reduce operating time, may lead to similar weight loss (some studies show that mini-gastric bypass may actually produce more weight loss), and reduce overall complication rates compared to gastric bypass surgery
What are the benefits of a mini-gastric bypass surgery?
The primary benefits of mini gastric bypass are that they offer results comparable to a traditional gastric bypass through a shorter and less invasive surgical procedure. That typically means an easier recovery process with less chance of complications.
Mini-gastric bypass is a quicker operation compared to traditional laparoscopic gastric bypass surgery. Operating times are reduced, on average by 50 minutes. Pain is usually not an issue. Yes, you will be in some pain. This is particularly true during the first two weeks and is very evident when you twist your torso. Pain can be managed well with medication.
What are the benefits compared to Gastric bypass?
- Shorter operating time.
- Less re-routing of the intestines.
- One fewer anastomosis (connection of intestines), which in theory means less chance of a complication.
- Technically easier for the surgeon.
- Similar weight loss and recovery.
Procedural steps:
- The stomach is divided with a laparoscopic stapler. Most of the stomach is no longer attached to the esophagus and will no longer receive food. Your new stomach is much smaller and shaped like a small tube.
- Between 2 to 7 feet of intestines are bypassed. The surgeon will attach the remainder of the intestines to the new stomach.
- Food now flows into your small tube-like stomach and then bypasses between 2 to 7 feet of intestines where it resumes the normal digestive process in you’re the remaining intestine.
Post-operative care.
After mini gastric bypass surgery, you will have to stay in the hospital for about 1 to 2 days. Your doctor will prescribe pain relieving medications to keep you comfortable. You will be given instructions to follow regarding wound care, diet and activity such as:
- Keep the incision area clean and dry.
- Avoid strenuous exercises and lifting heavy weights
- You may not be able to eat food for the first 1 to 2 days, after which you will be put on a liquid diet followed by pureed or soft foods.
- Sip water throughout the day to prevent dehydration.
- Follow the diet regimen given to you by the dietician.
- Follow an exercise program per your surgeon’s instructions to maintain the weight loss.
Risks and Complications.
As with any surgery there are potential risks and complications involved. Complications associated with Mini Gastric Bypass include:
- Problems associated with anaesthesia
- Bleeding
- Infection
- Leaks in your gastrointestinal tract
- Deep vein thrombosis (blood clot in the leg)
- Dumping syndrome leading to diarrhoea and nausea
- Intractable Bile Reflux
- Gallstones
- Malnutrition
- Marginal Ulcers
