The combination of mitomycin-induced blood cells with a temporary treatment of ciclosporin A prolongs allograft survival in vascularized composite allotransplantation.
Vascularized composite allotransplantation (VCA) is a rapidly expanding field of transplantation and provides a potential treatment for complex tissue defects. Peripheral blood mononuclear cells (PBMCs) shortly incubated with the antibiotic and chemotherapeutic agent mitomycin C (MMC) can suppress allogeneic T cell response and control allograft rejection in various organ transplantation models. MMC-incubated PBMCs (MICs) are currently being tested in a phase I clinical trial in kidney transplant patients. Previous studies with MICs in a complex VCA model showed the immunomodulatory potential of these cells. The aim of this study is to optimize and evaluate the use of MICs in combination with a standard immunosuppressive drug in VCA. ⋯ The findings of this study show that the combination of MICs with a temporary CsA treatment significantly prolongs the rejection-free interval in a complex VCA model. The combination of MICs with CsA showed no adverse events such as graft-versus-host disease. MICs, which are generated by a simple and reliable in vitro technique, represent a potential therapeutic tool for prolonging allograft survival through immunomodulation.

Robotic-assisted Roux-en-Y hepaticojejunostomy after bile duct injury.
The Da Vinci Robotic Surgical System has positioned itself as a tool that improves the ergonomics of the surgeon, facilitating dissection in confined spaces and enhancing the surgeon's skills. The technical aspects for successful bile duct repair are well-vascularized ducts, tension-free anastomosis, and complete drainage of hepatic segments, and all are achievable with robotic-assisted approach. ⋯ Robotic surgery is feasible and can be safely performed, with acceptable short-term results, in bile duct injury repair providing the advantages of minimally invasive surgery. Further studies with larger number of cases and longer follow-up are needed to establish the role of robotic assisted approaches in the reconstruction of BDI.

Review Meta AnalysisRecovery after intracorporeal anastomosis in laparoscopic right hemicolectomy: a systematic review and meta-analysis.
Although intracorporeal anastomosis (IA) appears to guarantee a faster recovery compared to extracorporeal anastomosis (EA), the data are still unclear. Thus, we performed a systematic review of the literature with meta-analysis to evaluate the recovery benefits of intracorporeal anastomosis. ⋯ Although intracorporeal anastomosis appears to be safe in terms of postoperative complications and is potentially more effective in terms of recovery after surgery, further ad hoc randomized clinical trials are needed, given the heterogeneity of the data available in the current literature.
