The second Mexican consensus on hepatocellular carcinoma. Part II: Treatment.

Hepatocellular carcinoma (HCC) is more frequently manifesting as one of the main complications of cirrhosis of the liver, its principal risk factor. There have been modifications in its incidence over the past decade, related to an epidemiologic transition in the etiology of cirrhosis, with a decrease in the prevalence of hepatitis C and an increase in nonalcoholic fatty liver disease (NAFLD) as a cause, as well as the development of HCC in the non-cirrhotic liver due to NAFLD. Genetic markers associated with the disease have been identified, and surveillance and diagnosis have improved. Regarding treatment, surgical techniques, in both resection and transplantation, have advanced and radiologic techniques, at the curative stage of the disease, have enhanced survival in those patients. And finally, there have been radical changes in the systemic approach, with much more optimistic expectations, when compared with the options available a decade ago. Therefore, the Asociación Mexicana de Hepatología decided to carry out the Second Mexican Consensus on Hepatocellular Carcinoma, which is an updated review of the available national and international evidence on the epidemiology, risk factors, surveillance, diagnosis, and treatment of the disease, to offer the Mexican physician current information on the different topics regarding hepatocellular carcinoma. In this second part of the document, the topics related to the treatment of HCC are presented.

Operative safety of orthotopic liver transplant in patients with prior transjugular intrahepatic portosystemic shunts: A 20-year experience.

INTRODUCTION AND AIMS: Orthotopic liver transplant (OLT) is the definitive treatment of most types of liver failure. Transjugular intrahepatic portosystemic shunt (TIPS) and portocaval shunt placement procedures reduce the systemic vascular complications of portal hypertension. TIPS placement remains a "bridge" therapy that enables treatment of refractory symptoms until transplantation becomes available. The aim of the present study was to describe the operative impact of TIPS prior to OLT. MATERIALS AND METHODS: A retrospective review was conducted on patients that underwent liver transplant at the Hospital San José within the timeframe of 1999 and February 2020. RESULTS: We reviewed a total of 92 patients with OLT. Sixty-six patients were male and 26 were female, with a mean age of 52 years. Nine (9.8%) of the 92 patients had a TIPS, before the OLT. Preoperative Child-Pugh class, MELD score, and sodium and platelet levels were similar between groups. We found no difference in the means of intensive care unit stay, operative time, or blood transfusions for liver transplant, with or without previous TIPS. There was no significant difference between groups regarding vascular and biliary complication rates or the need for early intervention. The overall one-year mortality rate in the TIPS group was 11%. CONCLUSIONS: TIPS is an appropriate therapeutic bridge towards liver transplant. We found no greater operative or postoperative complications in patients with TIPS before OLT, when compared with OLT patients without TIPS. The need for transfusion, operative time, and ICU stay were similar in both groups.

[Uterine arteriovenous malformation as cause of uterine bleeding of sudden onset. Doppler ultrasound utility, other imaging methods and the minimally invasive treatment]. / Malformación arteriovenosa uterina como causa de hemorragia uterina súbita. Utilidad del ultrasonido Doppler de consultorio, otros métodos de imagen y tratamiento de mínima invasion.

Background: Uterine arteriovenous malformation is a rare disorder that can cause sudden life-threatening vaginal bleeding. Objetive: To present the clinical features in addition to the use of office gynecologic ultrasound and other imaging techniques in the diagnosis and minimally-invasive treatment of a patient with sudden vaginal bleeding resulting from a uterine arteriovenous malformation. Case report: A 31 year old woman presented sudden onset vaginal bleeding requiring the transfusion of 3 units of red blood cells. An initial diagnosis of uterine arteriovenous malformation was made using an office gynecological ultrasound and Color Doppler sonography. The patient was referred to interventional radiology for confirmation of the diagnosis and patient care. The diagnosis and localization of the uterine arteriovenous malformation was confirmed using magnetic resonance imaging. Therapeutic management proceeded with superselective angiography and embolization of the supplying arteries resulting in immediate symptomatic resolution. Conclusion: The use of office gynecologic ultrasound in combination with other imaging techniques is an important tool in the diagnosis and localization of uterine arteriovenous malformation. Embolization of supplying arteries is considered a safe and effective therapeutic option due to advances in radiologic intervention techniques. Advantages of this procedure include a minimally-invasive technique, low morbidity and preservation of uterine function.
