While lesions with intraperitoneal perforation have an almost imperative indication to surgery, whether or not to manage retroperitoneal perforations surgically is still an area of debate. The aim of the present work was to review the available clinical evidence on the operatively and medi cally treated ERCP-related retroperitoneal perforations. From MEDLINE/Pub Med databases 137 patients with retroperito neal perforation were included from 12 studies that met the selection criteria for data investigation and analysis. Twenty four patients were treated by prompt surgery; 113 were primarily managed conservatively and about 20% of these patients required surgery subsequently. Overall, the morbid ity and mortality were 15.4% and 6.6%, respectively. Although most patients with retroperitoneal perforation may benefit from a non-operative management, a considerable number of patients fail to respond to medical treatment and require sur gery afterwards. Identifying those patients who are at highest risk of poor outcome after conservative treatment should be considered a research priority.展开更多

Liver resection or liver transplantation is the therapeutic gold standards in patient with HCC. Due to advanced disease, extrahepatic metastases, or inadequate liver reserve, only 15% to 30% of patients with HCC can undergo to surgery （2）. Five-year risk of recurrence of HCC after resection is as high as 70% because the underlying chronic liver disease continues to put the patient at risk for the development of new cancer nodules （3）. Starting from the assumption that recurrence may be newly treated with surgery, laparoscopic approach is recommended,展开更多

As a consequence, AFP represents a useful but poorly manageable tool to increase the ability to better select HCC patients waiting for LT. Trying to find a "filrouge" in the recent literature, no definitive answers can be done to several open questions:(1) the best AFP value to adopt;(2) the best cut-off measurement; and(3) the best way to comfortably capture the effective, time-related, fluctuations of this biological marker. More, structured and prospective, studies using serial determination of AFP values within and without the context of locoregional therapies are needed in order to find the "ideal"(static and dynamic) cut-off values allowing to respond to all the still open questions in this field of transplant oncology.展开更多

METHODS From December 2001 to February 2016, 270 liver transplantations were performed at San Camillo Hospital. IH occurred in 78 patients(28.8%). IH usually appeared early within the first year post-orthotopic liver transplantation. In the first era, fascial defect was repaired by primary closure for defects smaller than 2.5 cm or with synthetic mesh for greater defects. Recently, we started using biological mesh(Permacol?, Covidien). We present a series of five transplanted patients submitted to surgery for abdominal wall defect correction repaired with biological mesh(Permacol?, Covidien). RESULTS In our cases, the use of biological prosthesis(Permacol?, Covidien) have proven to be effective and versatile in repairing hernia defects of different kinds; patients did not suffer infections of the prosthesis and no recurrence was observed. Furthermore, the prosthesis remains intact even in the years after surgery. CONCLUSION The cases that we presented show that the use of biological mesh(Permacol?, Covidien) in transplanted patients may be safe and effective, being careful in the management of perioperative immunosuppression andrenal and graft function, although the cost of the product itself has been the main limiting factor and there is need for prospective studies for further evaluations.展开更多
