All rights reserved.Introduction: Emergency department visits (EDV) and hospital readmission (HR) after bariatric surgery (BS) are important indicators of quality and safety in surgery, however there is little information on their characteristics in our national environment. Aim: In this work we analyze EDV and HR in patients undergoing a primary BS in a high-volume university center, and identify variables that could be associated with these indicators. Materials and Method: A retrospective observational study where we identified all patients undergoing Roux-in-Y gastric bypass (RYGBP) or primary laparoscopic sleeve gastrectomy (SG) performed consecutively at our institution during the period 2006-2007 and 2012-2013. Using our clinical records and prospective follow-up database, we identify those patients with EDV and/or HR in our hospital during the first 30 days after discharge. Results: 1146 primary BS were included, of these 53% (n = 613) were RYGBP and 47% (n = 533) SG. 8,03% (n = 92) of the patients had at least one EDV, of these 3,7% (n = 42) had an HR. The independent variables associated with EDV and HR were the operative time and preoperative body mass index (BMI). No statistical association was found, in the period studied, for the type of BS performed with EDV or HR. Conclusion: There is a low proportion of patients who require EDV and HR after BS, which demonstrates the safety of these interventions.

    Isolated manifestation of necrotizing vasculitis of the bladder. A case report
    (SPRINGER HEIDELBERG, 2008) Becker, A.; Astroza, G.; Quezada, N.; Riano, C.; Urrutia, J.; Guzman, S.
    Isolated vasculitis involving the bladder is rare. We describe a case of irritative voiding and hematuria with slightly elevated inflammatory parameters. In order to exclude a neoplastic process we performed cystoscopy and computed tomography. Secondary systemic causes such as lupus erythematosus or rheumatoid arthritis were excluded. Cytopathological examination of the biopsies showed necrotizing vasculitis of the small bladder vessels, which responded to treatment with steroids and cyclophosphamide.
