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.

Both Ligasure™ and Harmonic Ace® provide surgeons ergonomy, and no significant differences were shown in operative time and complications. Safety and efficacy in such demanding operations is of critical importance. Choice between these two shears lies with surgeon's preference.

We report a case of jejunoileal intussusception in a 42-year-old patient with Crohn's disease caused by a gastrointestinal stromal tumor. The patient complained of vague diffuse abdominal pain for a period of 4 mo. Intussusception was suspected at computer tomography and magnetic resonance imaging scans. Segmental resection of the small intestine was performed. Pathological examination of the surgical specimen revealed a gastrointestinal stromal tumor as well as aphthous ulcerations and areas of inflammation, which were characteristic of Crohn's disease. This is the first report of small bowel intussusception due to a gastrointestinal stromal tumor coexisting with Crohn's disease.

Giant paraesophageal hernias (PEHs) are associated with progression of symptoms in up to 45 per cent of patients. Recently, many series have reported that laparoscopic repair of PEH is technically feasible, effective, and safe. A retrospective review of the University of Athens tertiary care hospitals patient database and the patient medical records identified 45 patients who underwent elective repair of a giant PEH between 2002 and 2009. Elective laparoscopic repair of a giant PEH was attempted in 45 patients who were treated with Gore-Tex dual mesh with or without Nissen fundoplication. They all had a mesh repair. Intraoperative complications included one pulmonary embolism and one recurrent hernia. The use of a mesh seems to be effective in the treatment of large hernias. It appears to offer the benefit of a shorter hospital stay and a quicker recovery.

LSG represents a safe and attractive treatment strategy for morbidly obese adolescents and young adults with comorbidities. In this study group excellent resolution of excess weight and comorbid conditions is achieved 2 years after LSG.
