位置、直径、出血风险在食管胃底静脉曲张破裂出血患者分型中应用初探

Development of a classification system for gastroesophageal varices according to its location, diameter and risk of bleeding

目的初步探讨应用静脉曲张位置、直径、出血风险对食管胃底静脉曲张破裂出血患者进行分型（LDRf分型）的可行性。方法回顾分析381例因食管胃底静脉曲张破裂出血行内镜下急诊治疗患者，对静脉曲张位置、直径和出血危险因素进行分析，并尝试进行LDRf分型。结果食管胃底静脉出血好发于食管中下段，不同直径的曲张静脉均有出血，曲张静脉多见有红色征。所有患者均可进行LDRf分型，食管静脉曲张破裂出血患者中，Rf1共计133例（45．4％），RL共计160例（54．6％）；胃静脉曲张破裂出血患者中，眦共计47例（53．4％），Rf2共计41例（46．6％）。结论LDRf可用于食管胃静脉曲张的分类并对诊断治疗有一定指导意义。

Objective To evaluate the feasibility of developing a novel classification system for gastroesophageal varices according to its location（L）, diameter（D） and risk of bleeding（R）. Methods The data of 381 patients with gastroesophageal variees, who underwent emergency endoscopy because of variceal bleeding, were retrospectively analyzed. The varices were classified into different types according to their location, diameter and risk of bleeding （LDRf）. Results Bleeding was most common in varices located at middle and lower part of the esophagus, and red sign on variees was a risk factor of bleeding. All varices could be classified into one certain type according to LDRf. Of 293 cases of esophageal varices, 133 （45.4%） were Rf1 and 160 （54. 6% ） were Rf2 ; of 88 cases of gastric varices, 47 （53.4%） were Rf1 and 41 （46. 6% ） were Rf2. Conclusion The LDRf classification system is feasible in gastroesophageal varices.
