Sleeve Gastrectomy versus gastric bypass surgery


In my opinion, both procedures are effective for weight loss. Gastric Sleeve is less invasive, has less down time and quicker recovery time. You will need one night hospital stay. You will loss significant weight and there is usually no need for supplemental vitamins. With gastric bypass surgery, you could potentially loss more weight. It is more invasive, has longer down time  and may require lifetime of supplements. The best procedure is the one that is selected based on your BMI, your underlying medical condition(s) and the procedure that your surgeon and his team are most comfortable with.

Sleeve Gastrectomy is preferable to Gastric bypass


Yes, it's true that studies show slightly better early weight loss with Gastric bypass than with sleeve gastrectomy; but that comes at a price of more than twice the rate of short-term complications (including death).  Add in the long-term risk of internal hernia, anemia, and osteoporosis, which essentially NEVER occur with sleeve gastrectomy... and to me, there's no question that sleeve gastrectomy is a better option for most patients.

There are also other problems that are being discovered with gastric bypass, such as insulin hypersecretion, which may contribute to long-term weigh regain.

And finally, since both patients carry a risk of weight regain, it is important to note that sleeve gastrectomy has the most salvage options, from re-sleeve, to plication, to conversion to duodenal switch.  There are no good options for patients who regain after gastric bypass.

Choosing Between Sleeve Gastrectomy and Gastric Bypass


The gastric bypass is still considered the gold standard for bariatric surgery worldwide. There is greater weight loss, better control of co-morbidities, and lesser weight regain in most series of gastric bypass compared to the sleeve. Long term results of sleeve gastrectomy (Doctor Weiner in Germany has one of the largest data) show significant weight regain in sleeve patients after five years. Therefore, if one can find a really skilled surgeon who does a lot of bypasses, with low morbidity, the bypass would be the preferred procedure. Sleeves are a reasonable choice in patients who have significant anemia, are smokers, or have had previous intestinal surgery. Your surgeon, if he is skilled in both procedures, should be able to help you make the right decision.
