Disadvantages of sleeve gastrectomy were usually related to the magnitude of surgery:

• Complications, although rare, and are usually more serious when compared with other weight loss surgeries, like gastric banding. If a leak occurs it may be a problem which can take some months to resolve the problem. The sleeve gastrectomy was relatively a new surgery. This surgery results in very little long-term data (data which will extends to over 10 years) to know what is happened with the weight loss. It is likely that sleeve will dilate with the time & weight loss will not be as good after 10 years as it was after 1 to 2 years. All bariatric surgeries will suffer in some way with the problem.
