Seroma formation was a major problem with the non-perforated Surgisis mesh repair, as was the post-operative pain. On the other hand, post-operative diastasis and hernia recurrence were a major problem with the Alloderm mesh. Further design improvements are required in both forms of these new mesh products. Surgeons should be aware of these potential complications prior to the selection of either of these products and the patient should be informed and educated accordingly.

In patients in whom gastroplasty, gastric bypass or both have failed to provide adequate weight loss, or worse have resulted in complications, DS can be performed as a safe revisional operation. The revision of other failed bariatric operations to DS results in both weight loss and resolution of the complications.

DS improves both hepatic steatosis and its resulting inflammation. No detrimental effects on hepatic function were noted after 6 months.

Carcinoid is a rare gastrointestinal tumor. We have noticed a high incidence of carcinoid in our patient population during the gastric reduction-duodenal switch operation. Further studies are needed to identify any potential correlation between morbid obesity and carcinoid tumors.
