WHAT IS MINI GASTRIC BYPASS SURGERY?
The traditional gastric pass surgery has garnered excellent results for weight loss. However, the procedure is technically challenging and carries a potential risk of 7 % for any kind of complication. The newly popular mini gastric bypass was developed in 1997 by Dr. Rober Rutledge. It is quicker, technology friendly and much safer procedure than the traditional surgery with a lower complication rate of 2.9%. The mini gastric bypass procedure is restrictive and malabsorptive. It means that it restricts your food intake while reducing the size of your stomach. The procedure bypasses up to 6 feet of intestines thus reducing the absorption of food.
- Enter the abdominal cavity: 5 small (1 inch) incisions are made on the abdominal wall to allow the insertion of access ports. Surgical instruments are then passed through the various ports to complete the operation.
- Retraction of the Liver: The liver must be lifted out of the way in order to complete the operation.
- Creation of the Mini-Stomach: The stomach is divided into 2 parts. One part, a long narrow tube that will serve as your new “mini-stomach”. The second part is the larger remaining part of your stomach which remains alive and well but is now “defunctionalized”, which means it no longer receives or processes food.
- Bypass of the small intestine: The length of small intestine bypassed varies usually ranging from 3 to 7 feet. The actual length of intestine bypassed will be determined by the surgeon based on multiple factors including your height and weight, your weight loss expectations, and a careful review of the risks and benefits.
- Removal of ports and closure of skin incisions: Upon completion of the operation, all instruments and ports are removed and the 5 small skin incisions are closed with skin closure staples.
Benefits of Mini Gastric Bypass
- Operating time is less: On an average of 50 minutes as compared to traditional gastric laparoscopic bypass surgery.
- Lesser re-routing of the intestines: The re-routing of intestines is much lower thus the operating time also is quicker.
- Technology friendly surgery: The mini gastric bypass surgery is new and advanced in terms of technology and much easier for the surgeons.
- Weight loss and recovery: The recovery is similar to that of a gastric bypass surgery, however, the complication rate is much lower at 2.9 %.
- Fewer anastomosis: This Is related to the intestines, which means lesser chances of a complication.
Potential Risks and Complications
- Severe acid flux: The gastric juices may enter the pouch as the lower section of the stomach is still connected to the intestines.Thus the juices can travel up and down causing such a problem.
- Pain: Minimal amount of pain will be there in the initial weeks of recovery.This will be because of the incisions made in the belly.
- Minor complications: Hernias incision infections, ulcers could develop at the surgical site.
- Major complications: Complications such as staple line leaks, pulmonary embolisms and strictures.These should be managed well & attentively by the surgeon.Before the surgery the patient should be informed of such risks and complications and symptoms for it.
