Three years of close follow-up of patients who had undergone laparoscopic sleeve gastrectomy demonstrated satisfactory weight loss results. Promising results were also obtained regarding various comorbidities of obese patients. Longer follow-up studies for more patients are needed to delineate the exact role of sleeve gastrectomy on postoperative outcomes.

This matched case-control study verifies the already reported lack of differences regarding IL-1. Controversy still exists on likely IL-6 differences. The inadequately studied IL-8 does not seem to play an important role in immunologic differences. The immunologically beneficial IFN-γ, produced by the principal effectors of cell-mediated immunity Th1 cells, seems to have a more active presence following laparoscopic colectomy, potentially contributing to an immunologic "advantage" by counteracting "harmful" cytokines, such as IL-1.

The authors conclude that complete laparoscopic excision of adrenal schannoma allows for a definitive histological diagnosis and treatment of choice.
