Interventional Sialendoscopy for Parotid Ductal Calculi: Our Preliminary Experience

With this article we present our initial experience with interventional sialendoscopy of the parotid duct for the parotid calculi. We carried out a prospective study of patients of parotid calculi in a tertiary referral centre. Diagnostic and interventional sialendoscopy was performed in five cases of parotid calculi. The outcome was classified on the basis of clearance of the lumen of the duct and resolution of symptoms. Diagnostic sialendoscopy was able to diagnose the calculus in all cases. Interventional sialendoscopy was done under general anesthesia in all cases and calculus was successfully removed. The average size of sialolith was 8.2 mm. No complications occurred in any of the cases. Check sialendoscopy was done in all cases after a minimum follow up of 6 months, which showed the duct lumen to be free of stone with no stricture of the duct. Sialendoscopy is an optimal technique for removal of intraductal parotid calculi and avoids removal of the gland. In our series there was no associated morbidity and complication.     

Tiny cystine stones in the gallbladder of a patient with cholecystolithiasis complicating acute cholecystitis: a case report

Cystine stones, the main component of which is cystine, are very common urinary calculi, but are rare in the gall bladder. In animals, there has been only one report of cystine gallstones in tree shrews, and to our knowledge, this is the first report of cystine gallstones in humans.     

American Public Health Association Meeting

Unit managers do need formal supervisory training. Training should focus on their approach to the decision making process as wel as their performance within it. Quality circle training was deemed most appropriate, because it focuses on team management and the development of skills needed to handle interactions in team settings.     

胆囊息肉样病变彩色多普勒超声检查的临床意义

<正>胆囊息肉样病变(polypoid lesions of gallbladder,PLG)又称胆囊隆起性病变,是一种常见的胆囊黏膜局限性隆起病变的统称,多数PLG为良性病变,但也有少部分为恶性或癌前病变。临床上对PLG直径10mm,并伴有临床症状的患者,多采用胆囊切除术作为治疗手段;对于息肉直径≤10mm的患者鉴别腺瘤和早期胆囊癌具有重要的临床意义[1]。本文对我院269例PLG患者的超声影像特征和手术病理结果进     

胆肠吻合术后吻合口结石的原因及预防

【摘要】 胆肠吻合术是重建胆道通路,使胆汁通畅引流的一种手术方式。术后吻合口结石成因复杂,治疗起来相对困难,且容易复发,这已经成为普外科医师亟待解决的临床难题之一。本文综述了胆肠吻合术后吻合口结石形成的原因,包括胆道系统术后病理生理改变、手术适应证的选择不当、原发病处理不充分以及术中操作不当及相应的预防措施,为今后胆肠吻合术后吻合口结石的防治提供参考。     

尿源性脓毒症的研究进展

尿源性脓毒症是指由于泌尿系统或者男性生殖器官的感染引起的脓毒症。近年来随着腔镜泌尿外科的发 展,尿源性脓毒症的发病率和相关死亡人数逐年上升。作为泌尿外科风险最大、预后最差的并发症之一,尿源性脓 毒症病情进展迅速,如对其未能早期诊断并及时正确处理,易迅速进展为脓毒症休克,危及患者生命。因此,早期 识别及正确诊治尿源性脓毒症对降低相关病死率和改善预后具有重要意义。尿源性脓毒症的治疗关键在于早期液体 复苏、早期使用抗生素及控制和消除易感因素,其围手术期处理需要外科,ICU,感染科及麻醉科医生之间的多学科协作及共同管理。本文就尿源性脓毒症的诊断标准及流行病学、病因及发病机制、危险因素和围手术期处理等相关研究进展作一综述。     

补充计量学研究可视化分析

本文对来自于中国知识基础设施工程（China National Knowledge Infrastructure,CNKI）数据库中研究补充计量学的相关文献进行收集整理,并使用CiteSpace软件进行可视化分析,分析方法有关键词聚类、作者聚类、作者合作网络等。分析结果显示中文补充计量学相关研究主要聚焦在补充计量学、学术影响力研究、科学评价研究、相关性分析研究、社交网络研究这几个方面。同时,分析结果也揭示出理论创新不足、合作研究较少等情况,建议这两方面进一步加强。     

晚期胆囊癌的外科治疗

目的：提高晚期胆囊癌的生存率及治疗效果。方法：对1990年1月至2001年6月我科手术治疗的80例晚期胆囊癌患者的资料进行回顾性分析。其中71例伴有阻塞性黄疸，15例扪及腹部包块，对已润周围器官及胆管但尚无肝脏广泛转移或远处转移的39例晚期胆囊癌进行了扩大根治术（其中11例合并胰十二指肠切除术），结果：该39例术后丰活8－37个月（平均存活18．1个月），1，2，3年生存率分别为43．6％，20．5％及5．1％，对另41例已有肝脏转移或腹膜种植转移的晚期胆囊癌仅行姑息性手术，术后随访除1例存活19个月外，其余均于1年内死亡，结论：对晚期胆囊癌的治疗应尽可能地行扩大根治术。
