Reduced port laparoscopic surgery using umbilical zigzag incision for Meckel’s diverticulitis

IntroductionReduced port laparoscopic surgery using an umbilical zigzag incision is comparable to conventional multiport laparoscopic surgery. This method is associated with improved cosmesis and decreased wound pain.Presentation of caseA 67-year-old man visited our hospital. He presented emergency room with a chief complaint of right lower abdominal pain by walking. The patient was diagnosed Meckel’s diverticulitis by computed tomography (CT). At first, antibiotics therapy and fasting were performed. Three months later, the patient underwent resection of Meckel’ diverticulum with zigzag transumbilical laparoscopic surgery. The patient’s postoperative course was good, and he rarely felt wound pain. The patient started oral intake three days after surgery, and was discharged 10 days after surgery.DiscussionZigzag transumbilical laparoscopic surgery is very useful for resection of the small intestine. This method is associated with improved cosmesis and decreased wound pain. In the case of Meckel’s diverticulitis, we suggest that interval resection of Meckel’s diverticulum was very useful as it was an operation that could be performed easily.ConclusionReduced port laparoscopic surgery using an umbilical zigzag incision is considered to be an excellent technique in terms of operability and aesthetic outcomes.     

Design and test of a vascular access device

Transarterial left ventricular assist devices (LVADs), such as the Hemopump, IABP, and PUCA-pump, are meant to be introduced into the body via the femoral or axillary artery without major surgery. For certain applications, introduction is performed directly into the aorta via an open thorax procedure. A prototype of a vascular access device has been realized that allows direct access into the aorta as an alternative for the common surgical graft anastomosis suturing technique. The device consists of a metal tube acting as a circular knife to cut a hole in the aortic wall, a screw to store the removed part of the aortic wall, and a plastic tube that is introduced through the hole and tightly connected to the aortic wall. The device could be placed without aortic clamping. The device has been tested on a slaughterhouse porcine aorta. A low-pressurized aorta appeared to be the worst case; thus, two animal experiments in the low-pressurized pulmonary artery were performed. No leakage occurred for pressures between 40 and 300 mm Hg.     

Assessment of pelvic stabilization devices for improved field reproducibility

The aim of this study was to evaluate the improvement in patient comfort and field positional accuracy provided by a new pelvic stabilization system when delivering multiple field radiotherapy to the pelvis. The Pelvic Cradle (BEHTS Manufacturing, Brisbane, Qld, Australia) is a stabilization device that provides reproducible patient positioning and levelling. Ninety patients were randomized into three groups. The first group was treated using the Pelvic Cradle, the second group was treated using current stabilization practices, and the third group was treated using the Pron Pillo (Chattanooga Pharmacal Company, USA) and current stabilization practices. Port films were assessed for field displacement in the lateral and cranio-caudal directions. A patient survey was used to evaluate the patient's perception of comfort while receiving treatment. When compared to the control group, the pelvic cradle group demonstrated a 48% improvement in the mean lateral deviation from 3.8 mm to 2.0 mm (P < 0.001) and a 36% improvement in the mean cranio-caudal deviation from3.9 mm to 2.5 mm (P < 0.001). The Pelvic Cradle was found to provide an improved level of field positional accuracy while maintaining patient comfort.     

可穿戴式心电、呼吸传感器与检测系统的研制

叙述了一种可用于移动条件下对重要生命信号（心电、呼吸等）无损检测的可穿戴式传感器及其测量和传输系统的研制。导电纺织面料缝合在普通背心内侧特定位置上作为检测电极，通过缝在背心上的导电纺织线将电极上的信号引出到背心边缘，再连接到信号测量和传输系统，由其中的单片机和激励、放大和处理电路测量心电、心率、呼吸数据，通过RS232串口、蓝牙等通讯方式传送到PC机上，用Visual Basic编写的程序接收并显示图形和数据。     

经药盒导管系统化疗栓塞治疗肝癌及相关药物监测

目的探讨经药盒导管系统(PCS)化疗栓塞治疗肝癌的临床价值。方法100例患者分成两组,PCS组(56例)经药盒导管系统灌注抗癌药与碘油混合成的乳剂,TACE组(44例)按常规方法栓塞治疗,对每组患者的疗效及药物代谢特征分别进行观察。结果PCS组患者肿瘤内的阿霉素可维持相当持久的较高浓度,7周后平均值7.9ug/克并取得较好治疗效果,其1、3年生存率分别为36/56(64%)及13/56(23%)。TACE组结果则较差,其阿霉素值为4.4ug/克,1、3年生存率分别为19/44(43%)及5/44(11%)。结论经PCS给药方法简便,疗效确切,经药物监测符合药代动力学规律,是治疗肝癌的较好方法。
