Effect of esophageal variceal sclerotherapy on hemorrhoids, anorectal varices and portal colopathy 总被引:3,自引:0,他引:3
BACKGROUND AND STUDY AIMS: Endoscopic sclerotherapy (EST) results in an increase in the prevalence of portal hypertensive gastropathy (PHG). However, the effects of sclerotherapy on hemorrhoids, anorectal or colonic varices and portal hypertensive colopathy are not known. The aim of this study was to investigate these effects. PATIENTS AND METHODS: A total of 39 patients with portal hypertension were studied. Upper gastrointestinal endoscopy and full-length colonoscopy were carried out before the patients underwent EST for esophageal varices, and after obliteration of the varices following sclerotherapy. RESULTS: The obliteration of esophageal varices by EST did not significantly affect the prevalence of hemorrhoids (32 % before and after), anorectal varices (45% before and after) or portal hypertensive colopathy (60.5 % before and 66 % after, P > 0.05). CONCLUSION: Obliteration of esophageal varices does not affect the prevalence of hemorrhoids, anorectal varices, or portal hypertensive colopathy. 相似文献

Colonic changes in patients with cirrhosis and in patients with extrahepatic portal vein obstruction 总被引:2,自引:0,他引:2
BACKGROUND AND STUDY AIMS: Figures for the prevalence of anorectal varices and portal hypertensive colopathy have varied considerably in the available studies of patients with cirrhosis, and few studies have observed these changes in patients with extrahepatic portal vein obstruction (EHPVO). Our aim was to investigate the colonic changes, if any, in patients with EHPVO and to compare them with those seen in patients with cirrhosis of the liver. PATIENTS AND METHODS: A total of 50 patients with cirrhosis and 35 patients with EHPVO, all of whom had a history of at least one episode of bleeding from esophageal varices, underwent both upper gastrointestinal endoscopy and colonoscopy. RESULTS: Anorectal varices were seen more commonly in patients with EHPVO than in patients with cirrhosis (63 % vs. 38 %, P < 0.03). Of the patients with anorectal varices, large anorectal varices were also more common in patients with EHPVO than in patients with cirrhosis (73 % vs. 32 %, P < 0.01). Colopathy was noted in 40 % of patients with EHPVO and in 62 % of patients with cirrhosis (P < 0.05). Of the patients with EHPVO, colopathy was noted in 27 % of patients who also had anorectal varices and in 61.5 % of patients without anorectal varices (P < 0.05). Similarly, patients with both cirrhosis and anorectal varices were found to have a lower prevalence of colopathy than cirrhotic patients without anorectal varices (42 % vs. 74 %, P < 0.03). CONCLUSIONS: Anorectal varices are more common in patients with EHPVO, while portal hypertensive colopathy is more common in patients with cirrhosis. Large anorectal varices are also more common in patients with EHPVO than in patients with cirrhosis and there is an inverse relationship between anorectal varices and colopathy in both cirrhotic patients and patients with EHPVO. 相似文献

Clinical relevance of colonic lesions in cirrhotic patients with portal hypertension 总被引:2,自引:0,他引:2
BACKGROUND AND STUDY AIMS: This prospective study was conducted in order to evaluate whether the colonic lesions previously described in cirrhotic patients may be of clinical relevance. PATIENTS AND METHODS: Eighty-five patients with cirrhosis of the liver, but without colonic or systemic diseases unrelated to the liver disease, underwent colonoscopy and were followed up for at least 2 years. RESULTS: Colonic varices were observed in 31 % of the patients, portal hypertensive colopathy (PHC; defined as diffuse hyperemia, edema, spider angiomas, and spontaneous bleeding of the colonic mucosa) in 54 %, and normal colonic findings in 18 %. Colonic varices and PHC were present simultaneously in 27 % of the patients. Previous sclerotherapy or band ligation treatment for esophageal varices had been carried out in 27 % and 23 % of the patients, respectively. Portal hypertensive gastropathy was observed in 42 % of the patients. Polyps were found in 12 % of the cirrhotic patients and cancer in 3 %. All of the patients were followed up for at least 2 years; 34 % of them developed upper gastrointestinal hemorrhage (81 % from esophageal varices, 19 % from the stomach), while only 6 % developed lower gastrointestinal bleeding. CONCLUSIONS: Colonic lesions are frequent in cirrhotic patients, but statistical analysis showed that these lesions are not specific for the disease and do not correlate with the etiology and degree of cirrhosis, with the endoscopic treatment of esophageal varices, or with the risk of bleeding from the lower gastrointestinal tract. 相似文献

Esophageal and gastric varices are common manifestations of advanced chronic liver disease, but other endoscopic gastrointestinal manifestations of portal hypertension may occur. In the upper gastrointestinal tract, portal hypertensive gastropathy, particularly when severe, and gastric antral vascular ectasias are important alternative causes of gastrointestinal bleeding. Portal hypertensive enteropathy is an uncommon source of gastrointestinal bleeding, and its overall clinical significance remains unknown. In the lower gastrointestinal tract, portal hypertension may be associated with hemorrhoids, anorectal varices, and portal hypertensive colopathy, all of which are occasional causes of gastrointestinal bleeding. 相似文献

The newer diagnostic and therapeutic options continue to evolve and important developments have been made in the field of variceal bleeding and portal hypertension. A meeting was held at Baveno to update consensus on different terminologies in relation to portal hypertension. beta-blockers continue to be the mainstay for primary prophylaxis of variceal bleeding, and endoscopic variceal ligation (EVL) is fast emerging as a strong contender. The role of vasoactive drugs in the management of variceal bleeding was assessed. Octreotide and terlipressin were shown to be as effective as sclerotherapy in achieving initial hemostasis, and octreotide was shown to be safe and efficacious in the prevention of rebleeding. EVL was superior to endoscopic sclerotherapy (EST) for obliteration of esophageal varices. Sequential and simultaneous ligation and sclerotherapy were more effective than ligation alone, in reducing the recurrence rate after variceal obliteration. For gastric varices, cyanoacrylate glue continues to be the first line of treatment, and band ligation is being assessed further. Bleeding ectopic varices were dealt by appropriate endoscopic means. Endosonography has developed strongly in the assessment of variceal eradication and prediction of variceal recurrence. Transjugular intrahepatic portosystemic shunting (TIPS) significantly reduces rebleeding rates compared to EVL. 相似文献

BACKGROUND AND STUDY AIMS: Endoscopic injection sclerotherapy (EIS) using cyanoacrylate and balloon-occluded retrograde transvenous obliteration (B-RTO) are the main procedures used to treat gastric varices. However, neither technique is free of problems. EIS for gastric varices may cause embolism in other organs; B-RTO requires a gastrorenal shunt and may aggravate esophageal varices. We have developed a combined form of endoscopic therapy involving band ligation and sclerotherapy which is an effective and safe procedure for treating gastric varices. PATIENTS AND METHODS: Fifty-six patients with gastric varices and liver cirrhosis were treated at Almeida Memorial Hospital from June 1997 to May 2002 using the combined procedure. Each gastric varix was tightly ligated with O-rings, and 1 % polidocanol was injected into the submucosa around the ligated varix. If necessary, additional sclerotherapy was carried out after the initial treatment. RESULTS: The rate of hemostasis for variceal bleeding was 100 %, and no critical complications were noted. Complete disappearance of the gastric varices was observed endoscopically in all cases. Computed tomography showed that collateral vessels outside the gastric wall were not occluded by the treatment. Endoscopic follow-up examinations were carried out, and gastric varices recurred in seven patients (12.5 %). Only two of the patients (3.6 %) had a small amount of oozing bleeding. Additional endoscopic variceal ligation (EVL) and/or EIS were performed in these seven cases, and none of the patients died as a result of a bleeding gastric varix. CONCLUSIONS: The combined procedure was easily performed immediately after endoscopic examination, and required no special apparatus. It was found to be a safe and effective method of treating gastric varices. 相似文献

During intravariceal sclerotherapy of esophageal varices with polidocanol in 32 patients with portal hypertension due to liver cirrhosis of various etiologies, endosonographic assessment of both esophageal and gastric intramural vessels was carried out in order to evaluate the usefulness of endosonography in the follow-up of the variceal status. In all cases endosonography demonstrated esophageal and gastric varices; in contrast, only five cases of gastric varices could be demonstrated by endoscopy. Furthermore, different stages of variceal obliteration following sclerotherapy could be demonstrated by means of endosonography, and it was possible to identify incomplete obliteration in about one-third of the patients in whom inadequate sclerotherapy was suspected endoscopically. In addition, the status of gastric varices during sclerotherapy was demonstrated by means of endosonography. Only in cases of adequate sclerotherapy of esophageal varices, as assessed by both endoscopic and endosonographic criteria, were gastric varices plugged. On the basis of these findings endosonography would appear to be a useful technique for the diagnosis and follow-up of esophageal and gastric varices during intravariceal sclerotherapy. 相似文献

BACKGROUND AND STUDY AIMS: Portal vein thrombosis is a rare event in patients with liver cirrhosis in the absence of a related neoplasm. Endoscopic sclerotherapy of esophageal varices has been anecdotally associated with the development of portal vein thrombosis. We tested the hypothesis that genetic thrombophilia plays a role in the development of portal vein thrombosis in patients with liver cirrhosis undergoing endoscopic sclerotherapy. PATIENTS AND METHODS: From June 1998 to December 1999, 61 consecutive patients underwent multiple sessions of endoscopic sclerotherapy for bleeding esophageal varices. Doppler ultrasound of the portal vein was performed before sclerotherapy and every 3 months thereafter. Antiphospholipid antibodies, factor V Leiden (FVL) mutation, prothrombin mutation G20210A (PTHRA20210) and mutation TT677 of methylenetetrahydrofolate reductase (MTHFR C677T) were evaluated in all patients. RESULTS: Portal vein thrombosis developed in 16 % of the patients (10 of 61) after a mean follow-up period of 16 months. A genetic cause for thrombosis was found in 70 % of patients with liver cirrhosis who developed portal vein occlusion, but only in 8 % of patients without this complication. CONCLUSIONS: Endoscopic sclerotherapy of esophageal varices may represent a trigger factor for portal vein thrombosis in cirrhotic patients with genetic thrombophilia. 相似文献

BACKGROUND AND STUDY AIMS: Acute variceal bleeding is a life-threatening complication of liver cirrhosis. Essential factors for survival after variceal bleeding are the rapidity and efficacy of initial primary hemostasis. Endoscopic and vasoactive therapy is the gold standard in the management of acute variceal hemorrhage. The primary aim of this study was to evaluate the use of self-expandable metallic stents to arrest uncontrollable acute variceal bleeding. PATIENTS AND METHODS: Between November 2002 and May 2005, esophageal stents were implanted in 20 patients (18 men, two women; mean age 52, range 27-87) with massive ongoing bleeding from esophageal varices, as an alternative treatment to balloon tamponade. The patients had not been successfully managed with prior pharmacologic or endoscopic therapy. They had had one to five previous bleeding episodes (mean 2.4). Eight of the patients were in Child-Pugh grade B and 12 in grade C. A new type of stent with special introducers was developed that allowed placement without radiographic assistance. RESULTS: The stents were successfully placed in all of the patients and were left in place for 2-14 days. Bleeding from the esophageal varices ceased immediately after implantation of the stent in all cases. While the stent was in place, further diagnostic steps were carried out to optimize management of the patients' illness and portal hypertension. No recurrent bleeding, morbidity, or mortality occurred during treatment with the esophageal stent. All of the stents were extracted without any complications after definitive treatment had been started. CONCLUSIONS: In this pilot study, the new method of implantation of an esophageal stent was found to be a safe and effective treatment for massive bleeding from esophageal varices in patients with liver cirrhosis. These initial clinical results will of course have to be confirmed in comparative studies including a large number of patients. 相似文献

BACKGROUND AND STUDY AIMS: The azygos vein plays an important role as a drainage system for the superior portosystemic collateral circulation in portal hypertensive patients. Endoscopic ultrasonography (EUS) and Doppler EUS allow the performance of hemodynamic studies of the azygos vein. In this study, we observed the changes in the azygos vein which occur with variceal obliteration by endoscopic injection sclerotherapy (EIS). PATIENTS AND METHODS: We recruited patients with portal hypertension and bleeding varices who were not on portal pressure-lowering agents and who were scheduled for the EIS program. EUS was performed in these patients to study the azygos vein at the start of EIS. The azygos vein diameter, maximal velocity (Vmax), and blood flow volume index (BFVI) were measured. After variceal obliteration and within 1 week, another EUS study of the azygos vein was carried out. RESULTS: Out of 40 patients recruited into the study variceal obliteration and EUS assessment of the azygos vein, within 1 week of obliteration, was achieved in 33. We noticed a significant increase in azygos vein diameter (P<0.001) and BFVI (P=0.001) following variceal obliteration. No significant change was observed in Vmax (P>0.05). In one patient, marked caliber irregularities were observed in the azygos vein after variceal obliteration. CONCLUSIONS: Using EUS and Doppler EUS, hemodynamic studies of the azygos vein blood flow can be performed, allowing the monitoring of the effects of EIS and variceal obliteration on the superior portosystemic collateral circulation. The clinical significance of the observed changes in azygos blood flow that occur with variceal obliteration should be investigated in further studies and correlated with short-term and long-term outcome. 相似文献

套扎与硬化剂比较治疗肝硬化食管静脉曲张出血的中文随机试验的系统评价 总被引:5,自引:0,他引:5
目的系统评价国内有关套扎治疗与硬化剂治疗肝硬化食管静脉曲张出血的有效性和安全性。方法计算机检索CBMdisc(1979~2006)和CNKI (1994~2006),收集有关套扎与硬化剂比较治疗肝硬化食管静脉曲张出血的随机对照试验(RCT)和半随机对照试验(CCT),由两名评价员独立对纳入文献进行质量评价和数据提取,并使用RevMan4.2.7软件进行Meta分析。结果共纳入9个RCT,包括1371例患者,其中套扎组688例,硬化剂组683例。Meta分析结果显示:对于死亡率,两组间差异有统计学意义[RR=0.60,95%CI (0.36,0.98)],套扎治疗组低于硬化剂治疗组;对于急诊止血率、出血复发率和并发症发生率,套扎治疗组也显示出更好的疗效趋势;而对于曲张静脉消失率和曲张静脉复发率,硬化剂治疗组则显示出更好的疗效趋势。结论在治疗肝硬化食管静脉曲张出血患者时,套扎较硬化剂治疗显示出更好的疗效及更少的并发症。但由于纳入研究质量不高,这一结论的强度受到一定的限制,尚需今后开展高质量随机对照试验来进一步验证。 相似文献
