Objective To observe the effects of endoscopic drug therap on hemostasis, re-bleeding and the risk of occurrence of complication in patients with acute esophageal and gastric variceal bleeding (EGVB). Methods A retrospective method was conducted, and 100 patients with EGVB who were admitted to the Affiliated Hospital of Yan'an University from June 2015 to June 2017 were enrolled. According to the difference in treatment methods, they were divided into an endoscopy Sclerotherapy and Ligation group and transjugular intrahepatic portosystemic shunt (TIPS) group, 50 cases in each group. The TIPS group was treated with TIPS; the endoscopy Sclerotherapy and Ligation group underwent endoscopic variceal sclerotherapy, endoscopic esophageal variceal ligation and postoperative non-selective β blockers oral administration. After 2 years of follow-up, the patients' hemostasis, re-bleeding at acute stage, survival situation and the incidences of complications were recorded. Before treatment and 2 weeks after treatment, the levels of serum albumin (Alb), total bilirubin (TBil) and platelet count (PLT) were measured by Hitachi automatic biochemical analyzer in the two groups. Results The success rate of hemostasis in the endoscopy Sclerotherapy and Ligation group was significantly higher than that in the TIPS group [98.0% (49/50) vs. 82.0% (41/50) ], and the recurrence rate of varices, during 1- and 2-year follow-up, the recurrence rate of bleeding and the incidences of complications were significantly lower than those in TIPS group [the recurrence rate of varicose veins: 6.0% (3/50) vs. 24.0 (12/50), 1-year re-bleeding rate: 12.0% (6/50) vs. 30.0% (15/50), 2-year re-bleeding rate: 42.0% (21/50) vs. 66.0% (33/50), esophageal ulcer: 2.0% (1/50) vs. 14.0% (7/50), upper abdominal discomfort: 2.0% (1/50) vs. 14.0% (7/50), hepatic encephalopathy:4.0% (2/50) vs. 16.0% (8/50), chest pain: 6.0% (3/50) vs. 20.0% (10/50), all P < 0.05]. After treatment, the levels of Alb and PLT in the endoscopy Sclerotherapy and Ligation group were higher than those in the TIPS group [Alb (g/L):43.84±4.34 vs. 40.83±3.21, PLT (×109/L): 26.33±3.37 vs. 21.12±3.89, both P < 0.05], and the TBil was lower than that in the TIPS group (μmol/L: 13.82±4.32 vs. 19.33±4.59). Conclusion Endoscopic Sclerotherapy and Ligation can significantly improve the effect of hemostasis of patients with acute EGVB, the rate of re-bleeding does not increase compared with that of western medicine group using TIPS, and the incidences of complications are significantly lower than those of applying TIPS.

Research on Relationship of Serum Urea Nitrogen Level and Upper Gastrointestinal Bleeding / 现代检验医学杂志

Objective To examine characteristics of patients with blood urea nitrogen (BUN) levels higher and lower than the normal limit.Methods During January 2012 to January 2015,116 patients with upper gastrointestinal diseases were selected to study,according to the patient's blood urea nitrogen level,all the patients were divided into high BUN group and low BUN group,and there were 76 patients in the high BUN group,and 40 patients in low BUN group,compared the biochemical indices,gastrointestinal bleeding forrest grading and disease severity of the two groups,and univariate logistic regression analysis.Results The serum white blood cell count,blood urea nitrogen,creatinine and glycated hemoglobin levels in patients of high BUN group [(9 593±5 012)× 102/μl,368.1±162.3 mg/L,11.2±3.7 mg/L and 6.38±1.08％] were significantly higher than that of low BUN patients [(6 804 ± 2 087) × 102/μl,121.0 ± 39.3 mg/L,8.1 ± 3.2 mg/L and 5.51 ± 0.42 ％] (t =3.645～12.659,all P＜0.05),and the hemoglobin levels (87.3±35.1 g/L) of the patients in high BUN group was significantly lower than that of the low BUN patients (108.0 ± 31.2 g/L) (t=3.252,P=0.032).Logistic regression analysis showed the presence of hemoglobin and glycosylated hemoglobin levelst of wo groups of patients was significantly different (P＜0.05),and showed that showed the highest correlation with BUN.Gastrointestinal bleeding forrest hierarchical data of the two groups of patients showed no significant difference (P＞0.05).The proportion of patients with gastric ulcers of high BUN patients was significantly higher than that of the low BUN patients (x2 =39.655,P=0.000).Conclusion Patients with high expression of serum urea nitrogen had more severe upper gastrointestinal bleeding,and it is worthy of attention in the process of clinical diagnostic.
