While conventional bariatric surgery seems to treat diabetes, many are evaluating procedures specifically geared to treat diabetes on its own. Conventional operations already in practice addressing obesity include laparoscopic adjustable gastric banding, Roux-en-Y gastric bypass, biliopancreatic diversion with duodenal switch, and sleeve gastrectomy. Laparoscopic adjustable gastric banding is strictly restrictive, with the band wrapping the proximal stomach, just below the gastro-esophageal junction.
The notion of surgery for diabetes brings with it certain understandings. First, surgery is by design an invasive treatment modality and carries risks related to both anesthesia and the procedure itself. Like with all other surgical treatments, patients will have to be carefully screened. For instance, not every patient with carotid stenosis merits or warrants an endarterectomy; likewise, a surgical treatment for diabetes is not for everyone.
