Match detection analysis on SentiMag® system and standard technique in SLNB of breast cancer.

Introduction: In breast cancer surgery, there are techniques for sentinel lymph node biopsy (SLNB) that do not require Nuclear Medicine, such SentiMag®, which uses ferromagnetic particles. The main purpose of this analysis is to study the degree of concordance in SLNB between SentiMag® and the standard method (Tc99 radiotracer). The secondary objective is to identify factors that impact in sentinel node detection rate and matching detection rate between both probes.

Duodeno-jejunal tube placement in an experimental model of obesity: effects on food behaviour and basal energy expenditure.

Background: Metabolic surgery can modulate weight as well as food intake and basal energy expenditure. In this study, we evaluate the effectiveness of duodenal exclusion by analysing anthropometric results, intake variations, food behaviour and calorimetric parameters.

Methods: This is an experimental study with 8-week-old Sprague-Dawley male rats.

[Evaluation of surgical skills in medical students using a virtual simulator].

Introduction: The use of virtual simulators together with hospital practicals during undergraduate training can improve basic surgical skills, and may even be an important motivating focal point. The aim of this work is to determine the endoscopy skill level and its learning curve in three stages within the Medical degree (second, fourth, and sixth year) using a virtual simulator.

Material And Methods: The Lapsim simulator with 7 basic modular exercises was used.

Gastric volvulus after sleeve gastrectomy for morbid obesity.

Background: Laparoscopic sleeve gastrectomy in morbid obesity has proved to be a safe and reproducible technique. Sleeve gastrectomy, however, is not free of complications. On the other hand, gastric volvulus is reported in those subjects where, either because of laxity of the gastric anatomical fixations or incorrect position of the stomach, rotation or turning is facilitated.
