Abstract
Introduction: Fecal incontinence is a common chronic disease, which not only brings inconvenience to the lives of patients, but also causes great psychological harm to patients. Artificial anal sphincter is an innovative method that may treat fecal incontinence, and now has been clinically applied.
Areas covered: This article will review recent developments in mechanisms and clinical applications of artificial anal sphincter. The current results of clinical trials show that the implantation of artificial sphincter will cause morphological changes of surrounding tissues, and related biomechanical imbalance will lead to the loss of effectiveness of the device and various complications. In terms of safety, postoperative patients suffer from various complications such as infection, corrosion, tissue ischemia, mechanical failure, and difficulty in emptying. In terms of effectiveness, there is currently no long-term research data to prove that the implanted device can maintain a long-term functional state.
Expert opinion: The key issue for the safety and effectiveness of implantable devices is the biomechanical compatibility of implantable devices was proposed. Based on the superelasticity of shape memory alloy, this article proposes a new type of constant force artificial sphincter device, which provides a new direction for solving the clinical application of artificial anal sphincter.
期刊介绍:
The journal serves the device research community by providing a comprehensive body of high-quality information from leading experts, all subject to rigorous peer review. The Expert Review format is specially structured to optimize the value of the information to reader. Comprehensive coverage by each author in a key area of research or clinical practice is augmented by the following sections:
Expert commentary - a personal view on the most effective or promising strategies
Five-year view - a clear perspective of future prospects within a realistic timescale
Key issues - an executive summary cutting to the author''s most critical points
In addition to the Review program, each issue also features Medical Device Profiles - objective assessments of specific devices in development or clinical use to help inform clinical practice. There are also Perspectives - overviews highlighting areas of current debate and controversy, together with reports from the conference scene and invited Editorials.
