To evaluate the safety and efficiency of variceal ligation compared with endoscopic sclerotherapy, 88 patients with cirrhosis with recent variceal bleeding were randomized to undergo either treatment.
Sclerotherapy was performed using ethanolamine and polidocanol injection at 1, 2, and 3 weeks and every 3 weeks thereafter. The Stiegmann-Goff device was used for variceal ligation at the same intervals.
The rate of variceal eradication was the same for both groups, but eradication was accomplished sooner in patients undergoing variceal ligation (5.3+/-1.6 vs. 6.6+/-2.4 endoscopic sessions, p < 0.05) and with fewer complications (19 vs. 6, p < 0.005). The rate of recurrent bleeding was lower in patients treated by ligation (31% vs. 50%, p < 0.05). After eradication, variceal recurrence was more frequent in patients treated by variceal ligation at 1 and 3 years (47% and 92% vs. 23% and 55%, p < 0.01). Portal hypertensive gastropathy was significantly worse in the patients who had variceal ligation (17 patients vs. 6, p < 0.01). Survival and treatment failure were similar in both groups.
Variceal ligation was superior to sclerotherapy in terms of the rate of recurrent bleeding and the occurrence of complications but worse with respect to recurrence of varices and the evolution of portal hypertensive gastropathy. Long-term follow-up studies are required to find out whether there are deleterious effects of variceal ligation.
为评估与内镜下硬化治疗相比,静脉曲张结扎术的安全性和有效性,将88例近期有静脉曲张出血的肝硬化患者随机分组接受其中一种治疗。
硬化治疗在第1、2、3周使用乙醇胺和聚多卡醇注射,此后每3周注射一次。使用施蒂格曼-戈夫器械以相同间隔进行静脉曲张结扎。
两组的静脉曲张根除率相同,但接受静脉曲张结扎的患者根除完成得更快(内镜治疗次数分别为5.3±1.6次和6.6±2.4次,p<0.05),且并发症更少(分别为19例和6例,p<0.005)。结扎治疗的患者再出血率更低(31%对50%,p<0.05)。根除后,静脉曲张结扎治疗的患者在1年和3年时静脉曲张复发更频繁(分别为47%和92%对23%和55%,p<0.01)。静脉曲张结扎患者的门脉高压性胃病明显更严重(17例对6例,p<0.01)。两组的生存率和治疗失败情况相似。
静脉曲张结扎术在再出血率和并发症发生率方面优于硬化治疗,但在静脉曲张复发和门脉高压性胃病进展方面更差。需要进行长期随访研究以确定静脉曲张结扎术是否存在有害影响。
