CT定位穿刺经胆肠Roux-en-Y吻合输出袢通路治疗肝内胆管结石1例

胆肠Roux-en-Y吻合术后肝内胆管结石复发或胆肠吻合口狭窄比较常见,通常需要通过再次经腹手术来处理,亦有通过经皮经肝胆道镜取石术和留置皮下空肠盲袢,或经小肠ERCP等创伤小的胆道通路来解决。2023年12月我院收治1例肝内胆管结石患者,无合适经皮肝或空肠盲袢通路,通过CT定位下经皮穿刺建立胆肠Roux-en-Y吻合输出袢通路取出结石,诊疗经过顺利,无并发症发生,报告如下。

腹腔镜Roux-en-Y胃旁路术后内疝肠梗阻的防治

随着腹腔镜Roux-en-Y胃旁路术的开展,手术例数逐渐增加,其并发症的防治至关重要。肠梗阻是腹腔镜Roux-en-Y胃旁路术的严重并发症之一,临床症状不典型,诊断假阴性率较高,容易发展为肠坏死,造成严重后果。因此预防、诊断、治疗腹腔镜Roux-en-Y胃旁路术后肠梗阻是减少围手术期死亡、肠坏死等严重并发症的关键。内疝是肠梗阻最常见的病因,预防、早期诊断、治疗内疝可预防大部分肠梗阻的发生。本文现总结国内外减重代谢外科医师的工作经验,对腹腔镜Roux-en-Y胃旁路术后内疝肠梗阻的发病情况、影响因素、诊断要点、治疗方法及预防措施作一综述。

肝胆管盆式Roux-en-Y吻合术治疗复杂肝内胆管结石一例

左右叶肝内同时存在多发肝内胆管充满型成堆结石,或全肝5个或以上肝段内存在多发肝内胆管充满型成堆结石,而且不能通过肝段和(或)肝叶切除来除净的肝内胆管结石即称为复杂肝内胆管结石^([1-2])。目前临床上对复杂肝内胆管结石的治疗以肝切除术为主,少数甚至需要行肝移植术。有症状的肝内胆管结石既是患者的痛苦历程,亦往往是对外科医生的严峻挑战。70年代黄志强教授提出“解除梗阻、祛除病灶、取尽结石、通畅引流”的十六字原则。复杂肝内胆管结石治疗中采用盆式胆肠吻合术是指将已切开的1~3级肝管拼合、整形。

Heterogeneity of Outcomes Reporting in Trials Evaluating Traditional Chinese Medicine Breast Massage for Stasis Acute Mastitis: A Methodological Review

Objective To systematically analyze the current status of outcomes reporting in clinical trials on treating stasis acute mastitis with Traditional Chinese Medicine breast massage.Methods We searched CNKI,Wanfang,VIP,Sino Med,Pub Med,Web of Science,Embase,Cochrane library,JBI,CINAHL,Psyc INFO,Clinical Trials Registry Platform portal,Clinical Trials Registry,Australian New Zealand Clinical Trials Registry,Center Watch Registry from inception to May 15,2022 to find randomized controlled trials,non-randomized controlled trials,case series and cohort studies which reported the outcomes of stasis acute mastitis managed with Traditional Chinese Medicine breast massage,with search terms of mastitis,acute mastitis,lactation mastitis,puerperal mastitis,breast problem,breast engorgement,milk stasis,blocked ducked,breast pain,breast massage,and acupoint massage.Outcomes and the measurement schemes(measurement methods,timing of assessing outcome,frequency of assessing outcome,measurers)were extracted from the included studies.We used the Management of Otitis Media with Effusion in Children with Cleft Palate(MOMENT)to assess the quality of each study,then categorized outcomes derived from the included studies into different domains according to the Outcome Measures in Rheumatology Arthritis Clinic Trials(OMERACT)Filter 2.1 framework.Results We identified 85 clinical trials,in which 54 different outcomes were reported.A total of 81.2%(69/85)of studies were assessed as medium quality with a mean score of 2.6,and 18.8%(16/85)as low quality with a mean score of 0.9.These outcomes were organized in three core areas.Lump size(89.4%,76/85)was the most frequently reported outcome,followed by breast pain(69.4%,59/85)and milk excretion(68.2%,58/85).Five methods were used to assess lump size and four methods to assess breast pain.Conclusions The outcomes reported in clinical trials regarding stasis acute mastitis treated by Traditional Chinese Medicine breast massage are heterogeneous.Developing a core outcome set to achieve consistent standards for reporting outcomes and modalities for validation of the outcomes is clearly warranted.

Translation stalling and ribosome collision leading to proteostasis failure:implications for neurodegenerative diseases

Proteostasis denotes a cellular state in which protein synthesis,folding,and degradation are maintained at a homeostatic state such that an intact yet dynamic proteome is preserved.Cellular capacity to preserve proteostasis declines with age,which is assumed to contribute to the pathogenesis of age-related diseases.Proteostasis failure manifested as the formation of aberrant protein aggregates,including the amyloid plaques in Alzheimer’s disease(AD),Lewy bodies in Parkinson’s disease,and TAR DNA binging protein 43 inclusions in amyotrophic lateral sclerosis(ALS),is a defining feature of neurodegenerative diseases.
