According to this planned interim analysis, adjuvant HAI, when used in this dose and schedule in patients with resection of colorectal liver metastases, reduced the risk of death at best by 15%, but at worst the risk of death was doubled. Thus, the chance of detecting an expected 50% improvement in survival by the use of HAI was only 5%. Patient accrual was therefore terminated.
Microsurgical techniques are being increasingly applied in almost all surgical disciplines. However, the opportunities to learn these skills in a structured course are rare. We have conducted a 5-day microsurgical training course on a yearly basis since 1991. The course follows step-by-step training, starting with nonvital models for vascular and nerval microanastomoses. As the participants improve, exercises on laboratory animals are offered to close the gap between nonliving models and the clinical situation. Lectures provide theoretical and clinical background information. Clinical and experimental applications can be witnessed and practiced in a second part of the course. With this step-by-step curriculum, we conduct a successful training program, e.g., each participant is able to perform microvascular and nerval anastomoses on a reproducible basis. The organization, program, and execution of the training course are presented, together with an evaluation of the course concept by the participants concerning expectations, learning success, and level of satisfaction.
Acute liver failure after hepatic surgery is still plaqued with high mortality rate. Recently, a liver dialysis system (MARS) that allows detoxification of albumin-bound substances and may hereby support liver regeneration and patient's recovery has been developed. In the present study, we report our experiences with MARS dialysis in patients with liver failure after hepatic resection or transplantation. Between September 1999 and January 2001, five patients were treated with MARS (2-5 courses). Though beneficial effects such as improvement of encephalopathy and renal function as well as reduced bilirubin levels were recorded during MARS therapy, only one patient survived. Neither significant technical problems nor adverse effects occurred by using MARS dialysis. We conclude that in surgical patients, acute liver failure is usually part of a complicated clinical course affecting multipleorgan systems. Thus, it is difficult to determine the specific influence of MARS on patient's outcome. However, beneficial effects observed in our patients justify its continuous use and may stimulate further evaluation in controlled studies with surgical patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
