临床医学研究与实践2023年3月第8卷第9期恶性胆道梗阻是因胆管、胆囊、胰腺的恶性肿瘤及肝脏的原发性或继发性肿瘤等引起的胆管梗阻,此病可导致患者肝功能迅速恶化,并引发严重感染、消化道出血及肾衰竭,若患者未及时得到有效治疗,病情持续发展,可导致患者死亡[1]。外科根治术是此类患者的传统治疗手段,但大部分恶性胆道梗阻患者早期无明显症状表现,导致确诊时疾病多已发展至中晚期,此阶段患者已错失外科根治术的最佳时机[2]。经皮经肝胆道引流术(percutaneoustranshep-aticcholangialdrainage,PTCD)成为此阶段患者的首选治疗措施,其属于微创性姑息疗法,虽有一定应用价值,但疗效以改善病情为主,无法取得理想的根治效果,故需寻求更佳的手术方案[3]。经内镜胆道支架置入术是近年来随着医疗科技不断发展而衍生的新型手术方式,属于微创术式,可在明确胆道梗阻的性质、部位及范围,取得明确手术效果的同时,利用支架内引流管恢复胆汁在肠管中的作用,对促使患者肠道功能恢复、增加术后肠道营养吸收、恢复肝肠功能循环等均具有积极意义,可在保障疗效的同时,缩短患者的康复进程[4]。基于此,本研究分析经内镜胆道支架ClinicalstudyofendoscopicbiliarystentplacementinthetreatmentofmalignantbiliaryobstructionLUTianyou,WUTianwen,PANWeilai,TANBinsi(GeneralSurgeryDepartment,LuodingPeople'sHospital,Luoding527200,China)ABSTRACT:ObjectiveToanalyzetheclinicaleffectofendoscopicbiliarystentplacementinthetreatmentofmalignantbiliaryobstruction.MethodsAtotalof34patientswithmalignantbiliaryobstructionadmittedinourhospitalfromJanuary2014toDecember2018wereselectedaspercutaneoustranshepaticcholangialdrainage(PTCD)group(treatedwithPTCD),and30patientswithmalignantbiliaryobstructionadmittedinourhospitalfromJuly2020toFebruary2023wereselectedasstentgroup(treatedwithendoscopicbiliarystentplacement).Thetherapeuticeffectsofthetwogroupswerecompared.ResultsThetotaleffectiverateoftreatmentinthestentgroupwassignificantlyhigherthanthatinthePTCDgroup,andthedifferencewasstatisticallysignificant(P<0.05).ThetotalincidenceofcomplicationsinthestentgroupwassignificantlylowerthanthatinthePTCDgroup,andthedifferencewasstatisticallysignificant(P<0.05).Afteroperation,theliverfunctioni...
