Abstract：Esophageal varices bleding（EVB）isthemostsevere complicationoflivercirrhosis，witharebleeding rate as high as 60% 80% within one year after endoscopic treatment and a mortality rate of 25% 50% .Endoscopic injection sclerotherapy（EIS），as the current mainstream treatment，achieves emergency hemostasis rates exceeding 90% .The transparentcap，asanauxiliarydeviceduringEIS，significantlyenhances treatmenteficacybyimproving visualfieldand stabilizing targetveins.Thisarticlesystematicalyreviews theclinical valueof transparentcaps inEIS basedonrecent domesticand internationalresearch，focusing on six majoradvantages：efectivelyreducing intraoperative bleeding， optimizing visual clarity，improving operational precision，decreasingperforationrisk，reducingcomplicationrates，and shortening procedure time.However，there existsomelimitations，such aspotentialvascular injurydue tothecap's sharp edges.Although clinical reportsontransparentcap-asistedEIS foresophageal varicesremain limited，itshighsafety profile，operational simplicity，shortened procedureduration，and significantlyreducedcomplicationratesmakeithighly recommendable for clinical application.

食管静脉曲张破裂出血（Esophagealvaricesbleeding，EVB）是肝硬化最严重的并发症，也是引起肝硬化失代偿期患者最终死亡的关键原因[1-2]文献报道约 50% 的肝硬化患者合并EVB，首次出血率为 5%～15% ，内镜下治疗1年后再出血率高达60%～80% ，死亡率也较高，达 25%～50%[3.6] 。（剩余7588字）
