National survey on the management of primary hyperparathyroidism by Swiss endocrinologists

Background From the endocrine surgeon’s perspective, it is important to know how endocrinologists manage patients with primary hyperparathyroidism (pHPT). The aim of this survey was to evaluate the preoperative diagnostic workup and referral pattern for parathyroidectomy by Swiss endocrinologists. Materials and methods The survey was conducted by mailing a questionnaire to all members of the Swiss Society for Endocrinology and Diabetes in spring 2005. Results The questionnaire was sent back by 68 of 124 endocrinologists (55%). The median annual case volume of patients with pHPT was 6 (range 1–50). The mean fraction of these patients referred for surgery was 59 ± 24%. This fraction was significantly higher in the German-speaking part of Switzerland than in the French-speaking part (67 ± 21% vs 51 ± 27%). When considering surgery for asymptomatic pHPT, 62% of the endocrinologists rely routinely on the recommendations of the NIH consensus conference and 86% on the subsequent guidelines of the workshop in 2002. Sixty-seven percent of the endocrinologists routinely perform localization studies before possible referral for surgical exploration. Typically, they consisted of an ultrasonography of the neck (93%) and a ^99mTc-MIBI scintigraphy (80%). The impact of the availability of a minimally invasive surgical procedure on the number of patients referred for surgery seems to be considerable. Sixty-one percent of the participants would expand the indication for surgery if the operation could be done by a limited surgical approach. Conclusions In a relevant fraction of patients with pHPT, endocrinologists still do not regard curative therapy as mandatory. Surprisingly, there are significant cultural differences concerning referral patterns to surgery between the German-speaking and the French-speaking parts of Switzerland. Minimally invasive procedures seem to lower the threshold for referral for surgical therapy. This work was presented at the 2nd Biennial Congress of the ESES, May 2006, Krakow, Poland.

Robotic surgery in gynecologic oncology: evolution of a new surgical paradigm

Robotic surgical platforms were first developed with telesurgery in mind. Conceptualized by NASA and the military to provide surgical expertise to remote locations, some telesurgical success has been documented, but progress has been held back by communication bandwidth limitations. Telepresence surgery, where the surgeon is in proximity to the patient but is provided with an ergonomic console equipped with three-dimensional vision and autonomous control of wristed laparoscopic surgical instruments and energy sources, has shown efficacy first in cardiac and then urologic cancer surgery. Interest is currently focused on the application of this technology in the field of gynecology, with techniques being described to perform simple hysterectomy, myomectomy, tubal anastomosis, and pelvic reconstruction procedures. This article will review the application of robotic- and computer-assisted surgery in the specialty of gynecologic oncology.

X线透视导航技术在创伤骨科的应用

X线透视导航技术对创伤骨科尤为重要。因为术前骨折块及骨折移位的方向可发生改变,所以需在术中将骨折块整复对位后,才能进行透视图像的获取和导航手术操作。X线透视导航技术的优点包括减少X线暴露的时间、准确放置植入物、术中适时测量评估及改善创伤骨科的微创操作。随着软件和硬件的不断改进及发展,许多需要术中X线透视监控的手术操作现在都可以借助X线透视导航技术完成。我们过去四年的临床经验已证实X线透视导航技术的优点及不断扩大的应用领域。X线透视导航技术在不断进展,因此需要更多的临床实践来评价此技术的使用价值。另外,X线透视导航系统在虚拟外科环境的外科培训和评价中发挥重要作用。这一技术将不仅为年轻外科医生提供实践机会,而且也将产生设计外科技术资格客观评价系统的新领域。     

计算机辅助导航骨科手术及医用机器人技术在创伤骨科的应用

本文介绍了计算机辅助导航骨科手术(CAOS)及医用机器人技术在创伤骨科应用中的主要进展、当前在临床应用中存在的主要问题和相关对策,并对其未来的发展趋势进行了预测,同时简要介绍了北京积水潭医院创伤骨科在计算机辅助导航骨科手术及医用机器人技术方面的研究进展。当前骨科手术导航定位所应用的医学图象导引系统已经由使用单一的C型臂、CT等传统影像设备向应用三维C型臂、多模态图像处理系统等新型影像设备转变,基于多模态图像的导航系统将有可能成为导航手术的主流。医用机器人已经在自动化程度和人机交互模式方面,有了长足进展,摆脱了原有工业机器人的结构模式。医学图像后处理技术及其它相关信息技术极大地丰富了导航和机器人外科,只有在不断完善光学定位技术的同时,加大对其它定位方法的研究,才能够提高定位精度;要对相关设备进行开放式结构设计,使不同导航系统的注册软件能够互相兼容,手术器械能够通用,降低设备成本。骨科医生要正确认识计算机辅助导航骨科手术及医用机器人技术,在充分了解CAOS的技术特点、基本原理、操作程序的基础上,对要实施的手术具有深刻的理解,才能开展CAOS手术。目前,迫切需要建立CAOS技术标准、临床适应证和手术操作规范,进行CAOS产品之间的技术比较和评估,便于医生选择合适的CAOS产品。伴随快速发展的信息技术,数字化手术室、智能化微创导航手术系统、医用机器人辅助的远程医疗将有可能成为未来CAOS技术的主要组成部分。
