PERIOPERATIVE AND COMPLICATION MANAGEMENT FOR ADENOCARCINOMA OF THE ESOPHAGUS AND ESOPHAGOGASTRIC JUNCTION

Esophagectomy remains a challenging procedure both for the patient and the surgeon. Patient selection and evaluation aims at preventing individuals unfit for surgery or without chance of cure from this operation. The use of modern operative techniques and in some cases sequential strategies help reduce the operative trauma. Regional anesthaesia and an individualized concept of perioperative pain treatment, early extubation, fluid restriction, mobilisation and physiotherapeutic assistance aims at the prevention of pulmonary complications, one of the dominant threats to this patient population. Rapid recognition and aggressive diagnostic work-up of any complication, especially anastomotic leaks, in the post-operative period is essential to prevent an uncontrolled progression of pathophysiologic cascades. A close multidisciplinary cooperation of surgeons, anaesthetists, endoscopists, radiologists and other associated disciplines is essential to further reduce the perioperative morbidity and mortality in this demanding surgical procedure

Impact of daclizumab, low-dose cyclosporine, mycophenolate mofetil and steroids on renal function after kidney transplantation

Background. Early and long-term use of cyclosporine A (CsA) leads to increased risks of renal toxicity. We hypothesized that administration of daclizumab in combination with mycophenolate mofetil (MMF) allows a relevant reduction in the dose of CsA. Methods. We carried out a 3-year, prospective, randomized, controlled clinical multi-centre trial in 156 patients. The patients were randomized to standard treatment (CsA, MMF, steroids) or to high-dose daclizumab (first dose: 2 mg/kg), in combination with low-dose CsA, MMF and steroids. We maintained the mean CsA levels of daclizumab patients at 57% of standard patients (132 versus 216 ng/ml) on Day 7 post-transplant, and 84% by 6 months. Results. Primary outcome, creatinine clearance (with imputation of informative dropouts) at 12 months, was significantly better in daclizumab-treated (34 ± 17) than standard patients (29 ± 17; P = 0.028, two sided). Only 5 cases of BPAR were recorded in the daclizumab compared to 22 in the standard group (P = 0.0016). Daclizumab patients had 91% event-free survival after 1 year compared to 66% in standard patients (P = 0.00017). Conclusion. We demonstrate here that high-dose daclizumab in combination with lower CsA levels in adult renal transplant recipients is as or more effective than standard regimen (CsA, MMF, steroids) and may result in better outcomes at 12 months post-transplant with no increase in adverse reaction
