Abstract

Background/Aims: Endoscopic submucosal dissection (ESD) is the preferred technique for treating early gastric cancer (EGC). However, very few studies have been conducted in South America. This study aimed to assess the efficacy and safety of ESD for EGC. Methods: We analyzed data from a prospective cohort from 2013 to 2020. A total of 152 superficial gastric neoplasms that fulfilled the absolute or expanded criteria for ESD were included. Outcomes were en bloc, R0, and curative resection rates, incidence of adverse events, and length of procedure. Results: The age of the enrolled patients was 68.4±11.3 years. The number of included patients based on the absolute and expanded indications was 150 and 2, respectively. En bloc, R0, and curative resections were achieved in 98.0%, 96.1%, and 89.5% of the cases, respectively. Bleeding and perforation were reported in 5.9% and 6.6% of the cases, respectively. Histopathological examination revealed low-grade dysplasia, high-grade dysplasia, well-differentiated adenocarcinoma, and poorly differentiated adenocarcinoma in 13, 20, 117, and 2 cases, respectively. Conclusions: Our study shows that ESD performed by properly trained endoscopists in reference centers is safe and effective, with comparable therapeutic outcomes to those reported in the Eastern series.

Abstract

Resumen Fasciola hepatica es un parasito de la clase Trema-toda comun en paises en desarrollo. La infeccion en el ser humano se caracteriza por la triada de fiebre, dolor abdominal en el cuadrante superior derecho y eosinofilia. Se presenta el caso de una mujer de 67 anos procedente de una zona rural al norte de Lima, con historia de dolor abdominal de seis meses de evolucion, con una imagen hipodensa hepatica en el TAC abdominal y eosinofilia. La biopsia hepatica mostro un infiltrado inflamatorio con eosinofilia. En el diagnostico diferencial en pacientes con un tumor hepatico y eosinofilia, se deben incluir infecciones parasitarias como F. hepatica ; sobre todo en pacientes que proceden de areas endemicas.

Abstract

Objective: The objective of this study was to determine the prevalence of clarithromycin-resistant Helicobacter pylori in asymptomatic children in a rural community of Cajamarca (northern Peru). Results: Helicobacter pylori was detected in 17.2% (49/285) of the samples. Unboiled water consumption the most frequent associated factor in patients with positive PCR for H. pylori infection (93.9%). Clarithromycin resistant mutations were found in 79.6% (39/49) of the positive samples for H. pylori. The most frequent mutation was A2142G (46.9%), followed by the double-mutation A2142G–A2143G (28.6%). [ABSTRACT FROM AUTHOR]
