内镜下鼻胆管引流治疗急性梗阻性化脓性胆管炎(附25例报告)

目的探讨急性梗阻性化脓性胆管炎伴多器官衰竭的治疗方法。方法对25例急性梗阻性化脓性胆管炎伴多器官衰竭的患者采取以内镜下鼻胆管引流术、经鼻胆管冲洗及灌注抗生素为主的非手术综合治疗,观察患者治疗前后的血清总胆红素水平、B超下胆总管内径变化,并对患者临床资料进行回顾性分析。结果本组25例患者除2例需转外科急诊手术治疗外,其余23例内镜下胰胆管造影、内镜下鼻胆管引流术成功,胆汁引流通畅,多器官衰竭得以纠正,急性梗阻性化脓性胆管炎伴多器官衰竭治愈率为92.0%。结论对急性梗阻性化脓性胆管炎伴多器官衰竭患者采取内镜下鼻胆管引流术、静脉应用和经鼻胆管冲洗及灌注抗生素为主的综合治疗是有效、安全的。     

Microformats: Three Proposed Standards for Solving the Need for Standard Data Presentation

The continuous glucose monitor market is just starting to develop. Current trends in the availability of diabetes information tools highlight the need for standard data presentation for continuous glucose monitors. These trends and their implications are discussed. This article proposes a set of standards for blood glucose data presentation. If device manufacturers adopt these standards, they will ensure that their continuous glucose monitors meet both the short-term and the long-term needs of users. This should increase the demand for these monitors and enable future device developments that appeal to a wider range of users.     

双J管临床应用及美蓝在置管术中的作用

目的探讨双J管(双J输尿管支架管)在泌尿系疾病治疗中的应用效果以及美蓝在置放术中的作用。方法对215例患者采用放置双J管作内支架和内引流治疗,近期48例术中以美蓝协助定位。结果术后留置尿管5~7d,无切口感染、尿瘘等并发症。术后1~3个月拔除双J管,随访3~6个月,肾功能、肾积水明显好转,吻合口通畅。以美蓝协助定位者无双J管上移致拔管困难。结论双J管具有内支架和内引流作用,操作简单,引流效果好,并发症少,缩短住院时间。以美蓝协助定位,值得推广应用。     

泵式自体输血过滤引流系统在急症救护中的应用

自体输血、胸腔闭式引流，是缓解血源矛盾、赢得抢救时机、防治心肺衰竭及ＡＲＤＳ／ＭＯＦ的重要措施。笔者研制成功的手控泵式储血过滤引流系列在战地、灾害现场，以及平时的心肺手术中，共应用３０００余例，现重点对其功能设计和用于自体输血、紧急救护做讨论和评估。     

Experimental laparoscopic aortobifemoral bypass

The goal of the present study is to develop a technique for laparoscopic aortobifemoral bypass.Piglets weighing between 60 and 78 kg were anesthetized with halothane. The lateral retroperitoneal approach was preferred to the more familiar anterior transperitoneal approach and was successfully completed in 19 piglets. The piglets were placed in the right lateral decubitus position. The first port (2 cm) was inserted halfway between the tip of the 12th rib and the iliac crest. Four other trocars were placed in the retroperitoneum after balloon inflation had allowed creation of a space which permitted visualization of the aorta from the left renal artery down to the aorto-iliac junction. After evacuation of the retropneumoperitoneum, the cavity was maintained using an abdominal lift device and a retractor.Using this approach, we performed four aortobifemoral bypasses (end-to-end aortic anastomosis) after conventional intravenous heparinization (100 IU/kg) in less than 4 h. Blood loss did not exceed 250 ml and the hematocrit remained stable. Postmortem evaluation of the grafts revealed they were positioned as in a conventional bypass, their limbs having followed in the created retroperitoneal tunnels along the path of the native arteries. No mortality occurred before sacrifice of the animals. We believe that this first performed series of totally retroperitoneal laparoscopic aortobifemoral bypasses in the porcine model is useful in preparation for human application due to the anatomical similarities in the periaortic region.     

完全性肺静脉异位引流的手术治疗经验

为评估影响完全性肺静脉异位引流（ＴＡＰＶＤ）手术纠治的因素，本组纳入了２８例在中度低温体外循环和１５例在深低温停循环下手术纠治者。结果手术死亡４例，死亡率９．３％。随访３２例，２例肺静脉回流梗阻分别于术后５个月和２年３个月死亡。结论认为，ＴＡＰＶＤ必须早期手术防止肺血管阻塞性病变；术后定期随访；改进手术方法，防止心房内补片粘连所致肺静脉回流梗阻。     

Efficacy of an air-cleaning device equipped with a high efficiency particulate air filter in house dust mite respiratory allergy

The efficacy of an air-cleaning device equipped with a high efficiency particulate air (HEPA) filter (without further avoidance measures) was studied in patients allergic to house dust mite. The effects of the air-cleaner on indoor Dermatophagoides sp. levels, symptom score and bronchial hyperresponsiveness in nine mite-allergic patients were assessed using a cross-over controlled study. No significant effect was demonstrated on indoor Dermatophagoides sp. levels when comparing the period of air-cleaner activity (2 months) with the control period (2 months). The Dermatophagoides sp. levels in the houses studied were lower than the risk level for asthmatic attacks, making it difficult to assess any effect on asthma; however, neither bronchial hyperresponsiveness nor rhinitis symptom score were changed by air-cleaner activity. During the trial period, however the mean level of Dermatophagoides sp. allergen in the houses changed spontaneously from 4.4 micrograms/g (mean level in the first 2 trial months) to 1.75 micrograms/g of dust (second 2 months) (P less than 0.05). Owing to this change, the mean rhinitis symptom score also decreased (P less than 0.05), even if no significant correlation was demonstrated (r = 0.4 P = 0.089). HEPA filter air-cleaners appear insufficient as substitutes for standard avoidance measures in mite allergic patients.     

Endoscopic fistulotomy and biliary drainage as the ultimate palliative treatment for obstruction due to malignant tumors of the papilla of Vater

Summary This report describes the technique and results of endoscopic fistulotomy as a drainage procedure in cases of malignant obstruction of the biliary system from bulky and friable growths in the papilla of Vater. Fistulotomy, coupled with insertion of stents, was successful in seven of eight patients and was associated with relief of jaundice. It is suggested that the method be applied when conventional transpapillary insertion of stents is impossible either due to distortion of the papilla or bleeding of the growth on touch.
