Hepatic infarction with portal thrombosis

A case of hepatic infarction with portal thrombosis is reported. A 63-year-old woman with liver cirrhosis and esophageal varices was admitted for treatment of the esophagel varices. Endoscopic variceal ligation (EVL) and endoscopic injection sclerotherapy (EIS) were performed. Two months later, she experienced right hypochondralgia and right flank pain. Serum transaminase levels were suddenly elevated, and computed tomography scans of the liver showed multiple small nodular lesions. Her condition worsened, and she died of hepatic failure. Autopsy revealed splenic and portal vein thrombosis, multiple hepatic infarction, and evidence of chronic pancreatitis. We believe that liver cirrhosis and chronic pancreatitis were the main risk factors for the portal thrombosis, and the treatment for esophageal varices appeared to have triggered the thrombosis. The hepatic infarction was caused by the portal thrombosis.

Anti-osteoporotic effect of Erythrina variegata L. in ovariectomized rats

The present study was designed to investigate whether Erythrina variegata L. (EV), which belongs to the leguminous family, exerted any beneficial effects on bone in ovariectomized rats. Daily oral administration of the EV extract at 300 and 600 mg/kg for 14 weeks to rats prevented the OVX-induced increase in the serum OCN, ALP, and urinary DPD levels. Histomorphometric analysis of the proximal end of the tibia showed that the EV extract prevented the estrogen deficiency-induced decrease in trabecular thickness and trabecular area, as well as restoring the increase in trabecular separation in a dose-dependent manner. Moreover, the EV extract improved the energy absorption and stiffness of the mid-shaft of the rat femur. Thus, the present study clearly demonstrated that EV could suppress the high rate of bone turnover induced by estrogen deficiency, inhibit bone loss and improve the biomechanical properties of bone in the OVX rats.     

Application of a Remodeled Stiegmann-ligator to Esophageal Varix

Abstract: The Stiegmann-ligator has been recently proved to be useful for the treatment of esophageal varices. With those ligators, however, we found difficulty in performing ligation when the pathological change was on the tangent line or relatively large, such as F₃, or associated with concentrated RC signs. To overcome these problems, we modified the Stiegmann O-ring ligator by diagonally cutting the tip of the inner sleeve. Using this ligator, we conducted some animal-model experiments and clinical trials. In all cases, the remodeled ligator covered a wider range of lesions. We no longer encountered difficulties in performing ligation with the remodeled ligator when pathological changes were on the tangent line. The procedure did not cause any complications apart from temporary chest discomfort after surgery.     

超声内镜指导胃镜下食管静脉曲张套扎术在胃黏膜间质瘤中的应用

目的观察超声内镜指导胃镜下食管静脉曲张套扎术在胃黏膜间质瘤中的效果。方法经超声内镜检查诊断筛选胃黏膜下小间质瘤83例,大小0.6～1.5 cm,以食管静脉曲张套扎器行内镜下黏膜套扎术治疗,于术后3个月、半年随访观察。结果胃黏膜下良性小间质瘤83例均起源于胃固有肌层;胃贲门6例,胃底19例,胃体31例,胃窦27例,部分细针穿刺组织,病理符合率为100%,进行胃黏膜下间质瘤的套扎术,成功81例,成功率97.59%,超声内镜随访,间质瘤消除82例,随访清除率98.80%。结论在超声内镜检查指导下选择合适胃黏膜间质瘤,用食管静脉曲张套扎器套扎,治愈率高、安全、有效、简便,值得进一步推广。     

Venous ablation therapy: indications and outcomes

Venous disease has long been recognized as a progressive, debilitating, and recurrent problem. Until recently, venous insufficiency was often undertreated due to a lack of therapeutic modalities. During the past decade, an explosion in the treatment options has occurred. Endovenous ablation therapy has nearly replaced the conventional surgical treatments for patients with superficial venous insufficiency. Dramatic changes in therapy are also available for deep venous thrombosis but are not the subject of this review. These newer techniques are much less invasive and consequently have reduced risks of wound complications or bleeding. In addition, they can be performed easily in the office setting with local anesthesia. Higher-risk patients can now be considered for these less invasive treatments to reduce their ambulatory venous hypertension. With the lower procedural risks and the dramatically shortened recovery times, earlier intervention can be entertained. This helps prevent the development of venous stasis ulceration and other sequelae of progressive venous insufficiency.     

Endoscopic treatment of esophagogastric variceal bleeding in patients with noncirrhotic extrahepatic portal vein thrombosis: a long-term follow-up study

BACKGROUND: Esophagogastric variceal bleeding is the most important complication of extrahepatic portal vein thrombosis (EPVT) and is usually treated endoscopically. Little is known about the prognosis of these patients. OBJECTIVES: To investigate the long-term clinical outcome and efficacy of endoscopic treatment in patients with esophagogastric variceal bleeding secondary to EPVT. DESIGN: Retrospective observational study. SETTINGS: Single university center. PATIENTS: Twenty-seven consecutive patients with esophagogastric variceal bleeding, secondary to noncirrhotic, nonmalignant EPVT, who underwent endoscopic treatment between 1982 and 2005. INTERVENTIONS: Endoscopic band ligation and/or endoscopic sclerotherapy. MAIN OUTCOME MEASUREMENTS: The overall rebleeding risk, overall survival, complications of the endoscopic procedures, and predictive values of rebleeding. Analyses were performed by the Kaplan-Meier method and univariate Cox regression. RESULTS: All patients were followed-up after the first endoscopically treated variceal bleeding. A total of 241 endoscopic procedures were performed. In all patients, initial control of bleeding was obtained. The overall rebleeding risk was 23% (95% CI, 0%-24%) at 1 year and 37% (95% CI, 43%-83%) at 5 years. Extension of thrombosis into the splenic vein and the presence of fundal varices were significant predictors of rebleeding, with a nearly 5-fold increased risk for patients with EPVT and fundal varices at the time of the first variceal hemorrhage (hazard ratio 5.07, P = .01). A portosystemic shunt procedure was performed in 5 patients: 4 for variceal bleeding and in one patient for refractory ascites. Seven patients died, none from variceal bleeding. Overall 5-year and 10-year survivals were 100% and 62% (95% CI, 38%-96%), respectively. LIMITATIONS: Retrospective design. CONCLUSIONS: In patients with variceal bleeding secondary to EPVT endoscopic treatment, in particular, band ligation appears safe and effective. EPVT-related mortality is primarily determined by other causes than variceal bleeding.
