Revisions After LAP BAND Surgery
The revision rate for the LAP BAND is approximately 10% during the first two years due to either device-related problems or unsatisfactory weight loss. A complication specific to this type of procedure is slippage of the gastric band, which requires a follow-up procedure to fix the problem. While some patients will have the band replaced, others choose to revise to another procedure.
Revisions After Gastric Bypass Surgery
A gastric bypass revision is necessary in approximately 5 to 10% of patients over 5 years due to complications, unsatisfactory weight loss, or weight regain. Complications that may occur after gastric bypass surgery, such as ulcers, chronic vomiting, hernia, staple line failure, can often be improved through revisional bariatric surgery.
If gastric bypass fails a patient has several options, including:
- If the problem is lack of weight loss or weight regain, non-surgical approach includes examining eating habits and exercise routines and participating in nutritional counseling, exercise program, behavior modification therapy, psychological counseling, and support groups
- If the problem is lack of weight loss or weight regain, surgical options include placement of an adjustable gastric band on the stomach pouch, conversion to distal gastric bypass, and conversion to duodenal switch
- If stomach pouch or stomach opening has enlarged, a LAP BAND may be added to reduce amount of food that can be eaten and slow the movement of food from the stomach to the small intestine
- If stomach pouch or stomach opening has enlarged, the bariatric surgeon can try and fix the problem by re-operating to either remove more stomach and re-stapling the stomach line or stitching up the stomach opening to make it smaller, although it may only be a temporary fix and happen again
- If surgical complication, such as popped staple line, ulcers, or hernia, the bariatric surgeon will need to surgically repair the problem
- StomaphyX, a non-surgical revision for gastric bypass surgery, that treats the stretched stomach pouch or enlarged stomach outlet
Patient Criteria for Revisional Bariatric Surgery
Before a revisional bariatric procedure is performed, the patient will be examined by the bariatric surgeon to determine the cause of failure and to evaluate for the appropriate treatment options. Bariatric surgery is a very specialized and complicated treatment process that doctors approach carefully. Great care is given to maximizing weight loss success while minimizing risks and complications. The bariatric surgeon will need to determine if post operative weight loss failure is due to a problem with the original surgery or the patient’s inability to follow the necessary lifestyle changes. The doctor will want to discuss the options and what a patient should expect with the bariatric revision.
Results with a Bariatric Revision
Although the results can vary widely depending on the original procedure and the reason for the revision, bariatric surgery revisions are usually successful in resolving the associated problems and promoting further weight loss. Weight loss following a revision is usually not as dramatic as the initial bariatric procedure, but it can be substantial over time. As revision surgery can be more complex and involve more risks than general bariatric surgery, it is important to choose a bariatric surgeon that is experienced and skilled in performing revision bariatric surgery and that the operation is performed as a medical facility that is designated as a Bariatric Surgery Center of Excellence.
As with all bariatric procedures, the best weight loss results are achieved by patients who are able to comply with the diet and exercise recommendations of their bariatric surgeon. The post-bariatric process can be a struggle and patients will benefit in their weight loss efforts by attending support groups, talking to a nutritionist for dietary advice, working out with a bariatric exercise program, and if needed talking to a psychologist to help deal with emotional aspect of obesity and weight loss surgery.
