Amyand's hernia in a patient with acute complicated diverticulitis. A case report and review of the literature.

Introduction: Amyand's hernia with an inflamed or perforated appendix is rare with incidence of 0.1 % and 0.01 % of cases respectively.

Laparoscopic Common Bile Duct Exploration Using a Disposable Bronchoscope.

Unlabelled: Laparoscopic common bile duct exploration (LCBDE) remains underutilized in the management of common bile duct (CBD) stones. The exact cause of this under-utilization remains unclear; however, identified barriers to LCBDE implementation include lack of training and unavailability of dedicated instruments. LCBDE is an attractive alternative for stone retrieval in patients with Roux-en-Y gastric bypass given the anatomical difficulty in endoscopic retrograde cholangiopaneatography (ERCP).

Indocyanine green fluorescence angiography in colorectal surgery. First case series in Mexico.

Introduction And Aim: Anastomosis leak occurs in 1-19% of colorrectal surgeries. Our objective was to present the first Mexican case series on colorrectal surgery using indocyanine green fluorescence angiography to evaluate perfusion prior to carrying out the anastomosis.

Materials And Methods: A retrospective, analytic, descriptive study was conducted.

[Severe bowel complications in SARS-CoV-2 patients receiving protocolized care].

Introduction And Aims: A case series of ten patients that received protocolized care for SARS-CoV-2 infection and developed severe gastrointestinal complications, is presented. The aim of our study was to contribute to the ongoing discussion regarding gastrointestinal complications related to SARS-CoV-2 infection. After reviewing the current literature, ours appears to be the first detailed case series on the topic.

Non-Hodgkin Lymphoma Epidemiology in Children From 2 Socioeconomic Regions in Mexico: 20-Year Registry (1996-2015).

Purpose: We analyzed the epidemiologic characteristics of different types of non-Hodgkin Lymphoma (NHL), excluding Burkitt Lymphoma, in 2 Mexican regions with different socioeconomic status.

Materials And Methods: In this surveillance study, we analyzed the incidence rates (cases per million children/year) of different types of NHL according to the ICCC3, registered in 1996-2015, from 2 different socioeconomic regions in Mexico: central and southern, with higher and lower status, respectively.

Results: The principal NHL subgroups were precursor (IIb1), mature B cell (IIb2), mature T/NK cell, and no other specification (NOS; 42.

Ampulary tumors: presurgical staging by endoscopic ultrasonography. Diagnostic test study.

Objective: To analyze the accuracy of endoscopic ultrasound (EUS) in the evaluation of ampullary tumors compared to histopathology (HP) staging.

Methods: A retrospective diagnostic test study. Patients with ampullary tumors staged by EUS and postpancreatoduodenectomy HP attended during 2012-2018 at tertiary level hospital.

[Bayesian analysis. Basic and practical concepts for its interpretation and use].

Bayesian statistics is based on subjective probability. It works with evidence updating considering the knowledge acquired prior to an investigation, plus the evidence obtained thereof. Results' interpretation requires for the hypotheses to be tested to be specified and their a priori probability to be estimated before the study.

[Clinical significance vs statistical significance. How to interpret the confidence interval at 95].

The validity of a study depends on its proper planning, execution and analysis. If these are sufficiently correct, the decision to apply the recommendations issued depends on the expected clinical effect. This effect may have random variations, hence the need to use statistical inference.
