目的研究肝硬化患者胆囊结石的发生率与肝功能分级的关系。方法回顾性分析195例肝硬化患者的临床资料,以同期230例健康体检者为对照组。结果肝硬化患者的胆囊结石发病率明显高于健康对照组(43.1%比6.1%,P〈0.01),且胆囊结石发病率与肝功能损害程度呈正相关,Child—PughB级和C级患者的胆囊结石发病率显著高于A级患者(A级25.5%比B级52.4%比C级44.7%,P〈0.01)。不同病因的肝硬化患者的胆囊结石发病率差异无统计学意义。胆囊结石为肝硬化患者合并急性胆囊炎、急性胰腺炎的主要原因(54.8%),经积极抗炎、利胆等对症治疗后大部分患者症状好转。结论肝硬化患者的胆囊结石发病率明显增加,并与肝脏疾病的进展呈正相关。 相似文献

Aim: This study investigated the relationship between portal hypertensive gastropathy (PHG) and splenomegaly, and the effect of laparoscopic splenectomy on PHG in cirrhotic patients with portal hypertension.
Methods: Seventy patients with liver cirrhosis and portal hypertension were prospectively studied. Indication for laparoscopic splenectomy was bleeding tendency in 10 patients, induction of interferon in 45, treatment of hepatocellular carcinoma in seven, and treatment for endoscopic injection sclerotherapy-resistant esophagogastric varices in eight. The severity of PHG was classified into none, mild, or severe according to the classification by McCormack et al. The severity of liver disease was classified using the Child–Pugh score. All patients underwent upper gastrointestinal endoscopy before and 1 month after the operation.
Results: The prevalence of PHG was significantly correlated with the severity of liver disease using the Child–Pugh score. The severity of PHG was significantly correlated with the resected spleen volume. One month after the operation, PHG was improved in 16 of 17 patients with severe PHG and in 12 of 32 with mild PHG. The Child–Pugh score showed a significant improvement (6.8 ± 1.4 to 6.2 ± 1.2) at 3 months after laparoscopic splenectomy ( P < 0.0001).
Conclusions: PHG may be associated with splenomegaly, and laparoscopic splenectomy may have a beneficial effect on PHG, at least for a short time. 相似文献

Expression of a 72-kDa heat shock protein, and its cytoprotective function, in gastric mucosa in cirrhotic rats 总被引:8,自引:0,他引:8
Watanabe D Otaka M Mikami K Yoneyama K Goto T Miura K Ohshima S Lin JG Shibuya T Segawa D Kataoka E Konishi N Odashima M Sugawara M Watanabe S 《Journal of gastroenterology》2004,39(8):724-733
Background Portal hypertensive gastropathy (PHG) is a clinical entity that is observed frequently in patients with liver cirrhosis. In PHG, gastric mucosa is highly susceptible to mucosal injury caused by noxious agents. Many studies, including ours, have reported that a 72-kDa heat shock protein (HSP72) has a crucial cytoprotective function in gastric mucosa. In this study, we investigated the expression and cytoprotective effect of HSP72 on gastric mucosa in portal hypertensive rats.Methods PHG was produced by bile duct ligation (BDL) or carbon tetrachloride administration in male Sprague-Dawley rats. The expression of HSP72 in the gastric mucosa was evaluated by Western blotting. Induction of gastric mucosal HSP72 by 6-h water-immersion stress was compared between cirrhotic and control rats. Also, mucosal protective abilities against hydrochloric acid (HCl; 0.6N) following pretreatment with water-immersion stress to induce HSP72 were studied in both groups.Results Portal venous pressure was significantly higher in cirrhotic rats compared with control rats (P < 0.05). Baseline expression (before water-immersion stress) of mucosal HSP72 was significantly lower in cirrhotic rats compared with control rats. HCl-induced gastric mucosal lesions were significantly suppressed in control rats compared with cirrhotic rats, especially when HSP72 was preinduced by water-immersion stress.Conclusions These findings suggest that HSP72 in the gastric mucosa plays a crucial role with respect to cytoprotection; the induction of HSP72 may provide therapeutic strategies for protection against mucosal injury in PHG. 相似文献

Portal hypertensive gastropathy (PHG) is a painless condition of gastric mucosal ectasia and impaired mucosal defense, commonly seen in patients with elevated portal pressures. While it is typically asymptomatic and incidentally discovered on upper endoscopy, acute and chronic bleeding may occur. There are no definitive recommendations for treatment of asymptomatic PHG. Non-selective β-blockers represent the mainstay of therapy for chronic bleeding, while somatostatin and vasopressin and their derivatives may be used in conjunction with supportive measures for acute bleeding. Salvage therapy with transjugular intrahepatic portosystemic shunt or rarely surgical shunt is appropriate when medical management fails. The role of endoscopic therapy for PHG is controversial. Liver transplantation should be considered as a final resort in cases of refractory bleeding due to PHG. 相似文献

目的探讨门静脉高压性胃病(PHG)胃镜下胃黏膜特征及其与食管胃静脉曲张、溃疡病及肝硬化并发症之间的关系。方法回顾性分析2012年8月-2018年6月陆军军医大学大坪医院867例肝硬化患者临床资料,统计其胃镜下食管胃静脉曲张、PHG、溃疡病发生的情况,收集肝硬化并发自发性细菌性腹膜炎、肝性脑病、原发性肝癌的数据资料。计数资料组间比较采用χ2检验,相关性分析采用Spearman相关性检验。结果肝硬化患者PHG发生率高达66.2%(574/867),轻度PHG胃黏膜改变以红点灶(68.6%)和蛇皮征(56.8%)为主,而重度PHG以弥漫红斑为主(76.5%)。PHG在不同程度的食管静脉曲张中发生率差异显著(χ2=304.712,P<0.05),并且随着食管静脉曲张加重,PHG程度亦越来越重(r=0.515,P<0.05)。不同程度胃静脉曲张的患者PHG发生率差异有统计学意义(χ2=81.004,P<0.05),且PHG程度与胃静脉曲张程度相关(r=0.292,P<0.05)。不同部位静脉曲张患者PHG的发生率差异显著(χ2=41.361,P<0.05),当患者仅出现胃静脉曲张时,PHG发生率(34.8%)最低,且均为轻度;而食管和胃均出现静脉曲张时,PHG发生率(85.6%)最高。未合并PHG患者中有71例(24.2%)因呕血和(或)黑便就诊住院,而574例PHG患者中有316例(55.1%)因此而住院,二者差异显著(χ2=74.562,P<0.05)。结论不同PHG严重程度的患者胃黏膜特征差异显著,PHG的发生和严重程度与食管胃静脉曲张程度密切相关,且是肝硬化消化道出血重要原因,应积极治疗和预防PHG以降低消化道出血风险和相关并发症。 相似文献
