自制内镜外套管在治疗食管胃静脉曲张出血中的应用

目的 探讨自制内镜外套管在治疗食管胃静脉曲张出血中的成功率及并发症的预防.方法 选择食管胃静脉曲张出血患者11例,采用内径1.05 cm、外径1.35 cm,长50 cm的钢丝强化塑料套管,将塑料制成的直径3.8 cm×3.8 cm气囊固定于套管的头部,其腔与尾部的注气管相连,尾部内镜插入口有防反流垫,侧面有冲洗孔的内镜外套管套在内镜外,随内镜一起插入食管胃内边冲洗边从外套管侧孔抽出积血.如发现食管静脉出血先用外套管头部气囊压迫止血,同时在其出血灶肛侧注射硬化剂,如发现胃静脉出血用外套管气囊压迫近贲门处的食管静脉,在其出血静脉注射硬化剂止血.结果 所有患者的出血病灶经外套管冲洗后视野清晰,暴露充分,给予血管内注射硬化剂后出血全部停止.未出现误吸、穿孔等并发症.结论 在急诊内镜治疗食管胃静脉曲张破裂出血中应用外套管可有效清除积血,保持视野清晰,是提高硬化剂止血成功率的有效方法 .

Application of self-made gastroscope outer casing in treatment of esophagogastric variceal bleeding

Objective To estimate the success rate of emergency endoscopic treatment in patients with esophagogastric variceal bleeding using self-made gastroscope outer casing and to investigate bow to prevent complications. Methods A total of 11 patients with esophagogastric variceal bleeding underwent endoscopic treatment with self-made gastroscope outer casing, which consisted of a wire reinforced plastic casing (1.05 cm in inner diameter, 1.35 cm in outer diameter and 50 cm in length), a 3.8 cm×3.8 cm balloon fixed on the casing head and its cavity connected to the gas pipeline placed in casing tail, an anti-reflux pad in the insert entrance of the endoscope tail as well.as a flushing hole. The endoscopy was introduced to the esophagus or stomch together with outer casing to wash and pump the hematocele out from the side of flushing hole. In patients with hemorrhagic lesion in esophageal vein, the balloon was used to press bleeding vein and intravascular sclerotherapy was performed simutanously. In those with hemorrhagic lesion in gastric vein, the balloon was pressed on esophageal vein near to the cardia and intravascular sclerotherapy was performed. Results During the process of examination, the hemorrhagic lesion was fully exposed because of flushing, and bleeding was controlted in all patients after sclerotherapy. No complication such as aspiration or perforation was seen. Conclusions For emergency endoscopic treatment of esophagogastric variceal bleeding, gastroscope outer casing is helpful in removing intragastric hematocele and maintaining a clear field of vision. It can be effectively improving the efficacy of sclerot herapy.
