    Antecolic versus retrocolic alimentary limb in laparoscopic Roux-en-Y gastric bypass: a comparative study
    (2007) Escalona, Alex; Devaud, Nicolas; Perez, Gustavo; Crovari, Fernando; Boza, Carnilo; Viviani, Paola; Ibanez, Luis; Guzman, Sergio
    Background: Laparoscopic Roux-en-Y gastric bypass (LRYGB) has become the most common surgical treatment for morbid obesity. Intestinal obstruction and internal hernias are cornplications more commonly observed after LRYGB than after open RYGB. The aim of this study was to evaluate the incidence of these cornplications in patients who had undergone LRYGB using an antecolic versus a retrocolic technique.

    Laparoscopic sleeve gastrectomy with ileal transposition (SGIT)
    (2008) Boza, Camilo; Gagner, Michel; Devaud, Nicolas; Escalona, Alex; Munoz, Rodrigo; Gandarillas, Monica
    Iroduction ariatric surgery has evolved into multiple forms in the last decades, combining food restriction and malabsorption. The aim of this study was to develop a new technique based on food restriction and early stimulation of the distal gut, thus maintaining the alimentary tract continuity.

    Resolution of early stage diabetic nephropathy in an obese diabetic patient after gastric bypass
    (2006) Perez, Gustavo; Devaud, Nicolas; Escalona, Alex; Downey, Patricio
    Epidemiological studies have proven that obesity is a significant risk factor for type 2 diabetes. Long-term progression of diabetes leads to various microvascular complications, of which diabetic nephropathy has become of increasing importance, and is the main cause of end-stage renal failure in occidental countries, Microalbuminuria is the first marker of incipient diabetic nephropathy, an early stage glomerulopathy which can progress to renal failure and which historically has been treated with angiotensin converting enzyme (ACE) inhibitors or angiotensin II receptor antagonists. We report a severely obese diabetic patient on treatment for diabetic nephropathy with ACE-inhibitors and poor results, which resolved after Roux-en-Y gastric bypass.

    Sleeve gastrectomy as obesity after orthotopic treatment for severe liver transplantation
    (2007) Butte, Jean M.; Devaud, Nicolas; Jarufe, Nicolas P.; Boza, Camilo; Perez, Gustavo; Torres, Javiera; Perez-Ayuso, Rosa M.; Arrese, Marco; Martinez, Jorge
    Obesity is highly prevalent in both liver transplant candidates and recipients, and can have a significant impact on perioperative morbidity and mortality and the overall cost of transplantation. Herein, we describe an obese patient who was managed sequentially with an intragastric balloon in the pre-transplant setting and a gastric sleeve following transplantation, with good long-term results. Sleeve gastrectomy is a non-malabsorptive bariatric procedure with potential benefit for liver transplant patients due to its lack of influence on the absorption of immunosuppressive agents.
