Introduction:In cholelithiasis, lipid and histopathological alterations have been found and suggest the accumulation of lipids in the gallbladder tissue (cholesterolosis), due to the few existing reports a study was carried out to determine their association. Objectives: The aim of the study was to evaluate the association between the lipid profile and gallbladder histopathology in patients with cholelithiasis undergoing cholecystectomy. Methodology: An observational, cross-sectional, analytical, and prospective study was carried out in a group of patients from the Hospital General de México "Eduardo Liceaga" undergoing elective laparoscopic cholecystectomy from January 2015 to January 2020. With approval of the protocol by the ethics and research committee, the following variables were considered: age, sex, BMI, comorbidities (diabetes, dyslipidemia, hypertension, cirrhosis) , LDL-C, HDL-C, total cholesterol, triglycerides, and histopathological findings (cholesterolosis, polyps, xanthogranulomatosis, acute cholecystitis, and cholecystitis chronicle). A descriptive and inferential analysiswas performed with SPSS v.24. It was considered p < 0.05 as significant. Results: From a group of 302 patients, 133 cases (108 women and 25 men) were included in the study. They presented overweight (39%) and obesity (33%), the lipid profile with hypoalphalipoproteinemia (61%), hypertriglyceridemia (40%), hypercholesterolemia (17%), and elevated LDL-C (16%); and in histopathology chronic cholecystitis (70%), cholesterolosis (28%), and acute cholecystitis (7%). Discussion: Our sample is representative of the Mexican population (in physical characteristics and lipid profile). However, no significant association was found between dyslipidemia and histopathological findings.

Background: Hernia is defined as a defect of fascial and muscle-aponeurotic structures, allowing the protrusion of elements. The most frequent is inguinal region, prevailing in men 3:1 vs female. The most frequent complications are persistent chronic pain.Methods: A descriptive, prospective and cross-sectional study was performed in postoperative inguinal plasty patients, using a laparoscopic approach and open approach, the presence or absence of inguinodynia was studied using the visual analogue pain scale (VAS) and the Semmes-Weinstein monofilament, in addition to a systematic investigation in the following PubMed, Medline, Clinical Key and Index Medicus databases, with articles from July 2019 to April 2020.Results: Inguinodynia was present in laparoscopic surgery and open approach, 58 patients had inguinodynia at two weeks associated with the inflammatory response of the tissues and the presence of a foreign body (mesh), 77% of the patients with persistence of pain at 3 months reported mild pain (VAS 1-4), 21% moderate pain that did not limit their daily activities (VAS 5-8) and 2% of the patients reported severe pain which limited physical activity and effort   (VAS 9-10).Conclusions: Inguinodynia has an impact on hospital costs and quality life, we consider it is essential to domain the anatomical variants of the region. We propose an extensive follow-up of this group of patients, to make a comparison of diagnostic methods, as well as conservative management vs. modern techniques for pain control.

Antecedentes. El cáncer pancreático es la séptima causa de muerte en el mundo, siendo el adenocarcinoma ductal del páncreas la neoplasia más frecuente. La mitad de los pacientes que son diagnosticados presentan metástasis al momento del diagnóstico. Objetivo. Se realizó una revisión sobre el tratamiento del adenocarcinoma pancreático resecable con enfermedad oligometastásica con el fin de presentar un panorama sobre la evidencia existente. Método. Se realizó una búsqueda bibliográfica en PubMed/Medline, Clinical Key e Index Medicus con términos MESH desde 1993 hasta 2022. Resultados. Los pacientes con metástasis hepáticas o pulmonares por adenocarcinoma ductal de páncreas que son sometidos a cirugía y quimioterapia tienen una mayor sobrevida en casos cuidadosamente seleccionados. Conclusiones. La evidencia respecto a la cirugía en pacientes con adenocarcinoma ductal de páncreas y oligometástasis es limitada y se necesitan ensayos controlados aleatorizados adicionales para ambos escenarios, así como criterios bien establecidos que ayuden a la selección de los pacientes que pueden recibir este tipo de tratamiento.
