Complications in Patients with Surgically Altered Gastrointestinal Anatomy Undergoing Endoscopic Retrograde Cholangiopancreatography: 15-Year Experience at a Tertiary Care Center in Latin America.

Background: Endoscopic retrograde cholangiopancreatography (ERCP) is a common procedure, but it poses challenges in patients with surgically altered gastrointestinal anatomy (SAGA). Alternative techniques like single-balloon enteroscopy (SBE), double-balloon enteroscopy (DBE), or push enteroscopy (PE) have been used, albeit with potential complications. Limited Latin American data exists on ERCP complications in SAGA patients.

Left psoas abscess due to duodenal fistula as a late complication of necrotizing pancreatitis treated by endoscopic approach.

Gastrointestinal fistulas can be a complication of severe acute pancreatitis, and their incidence is low and sporadically reported in the literature. The most frequently reported site is in the colon, followed by duodenal fistulas. Psoas abscess is a rare condition.

Hepatitis C virus-positive donors in HCV-negative recipients in liver transplantation: Is it possible in Mexico?

Hepatitis C virus (HCV) infection is a worldwide public health problem associated with significant morbidity and mortality. In the context of liver transplantation, the demand for organs continues to exceed the supply, prompting the consideration of using organs from HCV-positive donors in HCV-negative recipients. The introduction of direct-acting antivirals (DAAs), which have demonstrated great efficacy in eradicating the virus, has made transplantation of organs from donors with HCV infection possible.

Portopulmonary Hypertension: An Updated Review.

Portal hypertension may have major consequences on the pulmonary vasculature due to the complex pathophysiological interactions between the liver and lungs. Portopulmonary hypertension (PoPH), a subset of group 1 pulmonary hypertension (PH), is a serious pulmonary vascular disease secondary to portal hypertension, and is the fourth most common subtype of pulmonary arterial hypertension. It is most commonly observed in cirrhotic patients; however, patients with noncirrhotic portal hypertension can also develop it.

[Sustained virologic response in patients with hepatitis C and chronic kidney disease].

Background: Patients with chronic kidney disease (CKD) have a higher prevalence of hepatitis C virus (HCV) infection compared to the general population, and they also present higher morbidity and mortality if they are not treated. Current treatment is based on different direct-acting antiviral (DAA) schemes, which are available in the Mexican health system. However, the efficacy and safety of DAA treatment in patients with CKD on hemodialysis and HCV infection are unknown in Mexican population.
