Endoscopic self-expandable metal stent versus endoscopy vacuum therapy for traumatic esophageal perforations: a retrospective cohort study.

Background: Traumatic esophageal perforations (TEP) are a grave medical condition and require immediate intervention. Techniques such as Esophageal Self-Expandable Metal Stent (E-SEMS) and Endoscopic Vacuum Therapy (EVT) show promise in reducing tissue damage and controlling esophageal leakage. The present study aims to compare the application of EVT to E-SEMS placement in TEP.

The role of TNF-α and NFkβ in an experimental model of intestinal carcinogenesis with 1,2-dimethyhydrazine.

Purpose: To analyze the potential of tumor necrosis factor-α (TNF-α) and factor nuclear kappa B (NF-κB) as colorectal cancer (CRC) biomarkers in an experimental model of intestinal carcinogenesis with 1,2-dimethyhydrazine (1,2-DMH).

Methods: Twenty-four male Wistar rats were divided into two groups: sham and 1,2-DMH. First, 1,2-DMH (20 mg/kg/week) was administered for 15 consecutive weeks.

Pterostilbene and Probiotic Complex in Chemoprevention of Putative Precursor Lesions for Colorectal Cancer in an Experimental Model of Intestinal Carcinogenesis with 1,2-Dimethylhydrazine.

Dietary supplementation with pterostilbene (PS) and/or a probiotic (PRO) may ameliorate the intestinal microbiota in disease conditions. This study aims to evaluate PS and PRO for the chemoprevention of putative precursor lesions for colorectal cancer (CRC) in an experimental model of intestinal carcinogenesis with 1,2-dimethylhydrazine (1,2-DMH). Sixty male Wistar rats were equally divided into five groups: Sham, 1,2-DMH, 1,2-DMH + PS, 1,2-DMH + PRO, and 1,2-DMH + PS + PRO.

Evaluation tool for a gastroenterostomy simulated training1.

Purpose: To create a checklist to evaluate the performance and systematize the gastroenterostomy simulated training.

Methods: Experimental longitudinal study of a quantitative character. The sample consisted of twelve general surgery residents.

Effect of co-administration of BRL-37344 and tadalafil on reduction of overactive bladder symptoms after induction of detrusor overactivity in mice1.

Purpose: To evaluate the impact of the combination of BRL 37344 and tadalafil (TDF) on the reduction of overactive bladder (OB) symptoms.

Methods: Thirty mice were randomized into 5 groups (G) of 6 animals each. L-NAME was used to induce DO.

Hepatic retractor in an ex vivo model1.

Purpose: To discuss the use of models of hepatic retraction by laparoscopy, to present a new Hepatic Retractor (HR) and to evaluate its practicality, efficacy and safety in Esophageal Hiatus Exposure (EHE).

Methods: Experimental cross - sectional study with a quantitative character. It was carried out in the Laboratory of Health Training of Christus University Center.

Simulated training of a laparoscopic vesicourethral anastomosis.

Purpose: To develop a model and curriculum for simulated training of an effective and well accepted laparoscopic vesicourethral anastomosis (VUA).

Methods: Experimental longitudinal study of quantitative character. The sample consisted of 12 general surgery residents and 6 urology residents (R3).

LIVER TRANSPLANTATION IN HEPATITIS DELTA: SOUTH AMERICA EXPERIENCE.

Background: The Amazon region is one of the main endemic areas of hepatitis delta in the world and the only one related to the presence of genotype 3 of the delta virus.

Objective: To analyze the profile, mortality and survival of cirrhotic patients submitted to liver transplantation for chronic hepatitis delta virus and compare with those transplanted by hepatitis B virus monoinfection.

Methods: Retrospective, observational and descriptive study.

Model for simulated training of laparoscopic gastroenterostomy.

Purpose:: To develop a model of gastroenterostomy and to analyze the acquisition of skills after training by simulation.

Methods:: Experimental longitudinal study and of a quantitative character. The sample consisted of twelve general surgery residents from four hospitals.
