Pathology results of endoscopic ultrasound-guided tissue acquisition in retroperitoneal masses: a multicenter study.

Background: Malignant etiologies are found in 70-80% of symptomatic retroperitoneal masses. Histology is required for diagnosis and treatment. Information about endoscopic ultrasound (EUS)-guided tissue acquisition (EUS-GTA) is scant for retroperitoneal masses.

Comparing perspectives: frontal and oblique endoscopic ultrasound.

The oblique-view echoendoscope is currently the sole tool for ultrasound-guided endoscopic procedures (EUS) in most hospital centers, despite its limitations like a lack of forward vision, issues with needle angle, and restricted accessory device size due to channel angulation. However, our study revealed no significant differences between the oblique and frontal endoscopes, except for minor variations in specific regions. For routine diagnostic studies, interchangeability between the devices is feasible.

Circulating miRNAs as Noninvasive Biomarkers for PDAC Diagnosis and Prognosis in Mexico.

Among malignant neoplasms, pancreatic ductal adenocarcinoma (PDAC) has one of the highest fatality rates due to its late detection. Therefore, it is essential to discover a noninvasive, early, specific, and sensitive diagnostic method. MicroRNAs (miRNAs) are attractive biomarkers because they are accessible, highly specific, and sensitive.

Surgical site infection following pancreaticoduodenectomy in a referral cancer center in Mexico.

Background: Pancreaticoduodenectomy is the standard treatment for resectable periampullary cancer. Surgical site infections (SSI) are common complications with increased morbidity. The study aimed to describe the prevalence, risk factors, microbiology, and outcomes of SSI among patients undergoing pancreaticoduodenectomy.

Microbiological findings in bile cultures of patients with acute cholangitis undergoing endoscopic retrograde cholangiography.

Acute cholangitis (AC) is potentially fatal. Microbiological identification and susceptibility to antibiotics is essential in every hospital to direct treatment (1). Our hospital is a third-level cancer center.

Efficacy and safety of radiofrequency ablation in patients with unresectable malignant biliary strictures.

Introduction: previous studies have shown that endoscopic radiofrequency ablation in unresectable biliary duct tumors prolongs survival.

Methods: this was an observational study of patients with an unresectable malignant stricture. The aim was to evaluate survival, stent patency and adverse events of radiofrequency compared with a matched control group.

Fecal Immunologic Test Results and Diagnostic Colonoscopy in a Mexican Population at Average Risk for Colorectal Cancer.

Colorectal cancer is preventable and treatable by screening and early detection. Fecal immunochemical tests (FIT) for average risk individuals is an effective strategy for screening. Incidence and mortality in Mexico is increasing and large-scale screening programs do not yet exist.

Boceprevir and telaprevir for chronic genotype 1 hepatitis C virus infection. A systematic review and meta-analysis.

Background: Treatment of hepatitis C virus (HCV) infection with newer direct-acting antivirals is unrealistic in some countries because of the lack of availability.

Aim: Assess benefits and harms of boceprevir (BOC) and telaprevir (TLV) in treatment of genotype 1 HCV infection, and identifying subgroups with most benefit.

Material And Methods: Search from 2009-2013 in PubMed, EMBASE, and "gray literature" of published and unpublished randomized trials reporting sustained viral response (SVR) or adverse events (AE) with BOC or TLV + pegylated interferon and ribavirin (PR) in HCV-infected patients; cohorts or case reports for comparison protease inhibitors (PI), evaluation of predictors of SVR, and resistant variants.

Portal vein thrombosis: what is new?

Portal vein thrombosis (PVT) is one of the most common vascular disorders of the liver with significant morbidity and mortality. Large cohort studies have reported a global prevalence of 1%, but in some risk groups it can be up to 26%. Causes of PVT are cirrhosis, hepatobiliary malignancy, abdominal infectious or inflammatory diseases, and myeloproliferative disorders.

Granulomatous hepatitis caused by Q fever: a differential diagnosis of fever of unknown origin.

The differential diagnosis of fever of unknown origin (FUO) includes infectious, neoplastic, rheumaticinflammatory and miscellaneous diseases. We report the case of a 35-year-old man with FUO caused by Q fever. A liver biopsy showed the characteristic fibrin-ring lipogranulomas compatible with Q fever.
