Polypropylene mesh used to repair abdominal wall hernias routinely induces dense adhesions if there is direct contact between the mesh and the viscera. Adhesions may lead later to difficult reoperation, intestinal obstruction, or enteric fistula. ⋯ 1) Sepramesh alone reduces polypropylene mesh adhesions by roughly three-quarters. 2) Sepramesh plus Seprafilm nearly eliminates such visceral adhesions. 3) Mesothelial cell coverage of polypropylene mesh confers adhesion resistance.

Comparative Study
Hepatic resection with reconstruction of the inferior vena cava or hepatic venous confluence for metastatic liver tumor from colorectal cancer.
Resection of colorectal liver metastases infiltrating the inferior vena cava (IVC) or hepatic venous confluence (HVC) is technically feasible, but the procedure frequently involves invasive techniques, and its long-term outcome has not yet been fully described. ⋯ Hepatic resection combined with the IVC or HVC reconstruction for colorectal liver metastases can be performed with acceptable morbidity, and possibly with no mortality. Although no definite conclusion on long-term survival can be drawn from our study, given the limited number of patients, their overall survival was unsatisfactory. Further studies are needed to clarify the contribution of combined resection and reconstruction of IVC/HVC to long-term survival, because surgical resection currently provides the only hope of cure.

Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Use of an oxygen therapeutic as an adjunct to intraoperative autologous donation to reduce transfusion requirements in patients undergoing coronary artery bypass graft surgery.
The benefits of intraoperative autologous donation (IAD) in reducing the need for allogeneic blood transfusion in surgery have been debated for several years. The purpose of this study was to determine if IAD alone or in conjunction with hemoglobin raffimer (HR) confers a reduction in red cell or blood component transfusion compared with results in standard clinical practice. ⋯ In this study, patients treated with HR in conjunction with IAD received fewer transfusions overall and a lower volume of allogeneic RBCs and non-RBC allogeneic blood products than did the two comparison groups. This confers a real benefit on the overall blood supply by decreasing use and increasing availability.
