Characterization of Mesenchymal and Neural Stem Cells Response to Bipolar Microsecond Electric Pulses Stimulation.

In the tissue regeneration field, stem cell transplantation represents a promising therapeutic strategy. To favor their implantation, proliferation and differentiation need to be controlled. Several studies have demonstrated that stem cell fate can be controlled by applying continuous electric field stimulation.

O-Arm Navigation-Guided Unilateral Biportal Endoscopic Decompression of Far-Out Syndrome.

The main aim of this video article is to demonstrate the combined use of O-arm navigation and unilateral biportal endoscopy (UBE) to manage far-out syndrome (FOS). In FOS there is entrapment and compression of the fifth lumbar nerve beyond the foramen and between L5 transverse process and the sacral ala at the lumbosacral junction. Conventional microscopic decompression using a paraspinal approach had been the gold standard for its management.

Single incision laparoscopic appendectomy with surgical-glove port is cost-effective and reliable in complicated acute appendicitis: A casecontrol multicenter study in Colombia.

Background: The single-port (SPL) and multi-port (MPL) laparoscopic approach are the gold standard of management of acute appendicitis, due to its multiple advantages over open surgery, mainly because of its direct effects on recovery, esthetics and costs of the procedure. However, in third-world countries, the laparoscopic approach is not yet fully reproducible due to the costs of the technique. The surgical-glove port single incision laparoscopic appendectomy (SGP-SILA) has been proposed as a viable option.

Long-Term Outcomes of Laparoscopic Common Bile Duct Exploration Through Diathermy, Choledochotomy, and Primary Closure: A 6-Year Retrospective Cohort Study.

Choledocholithiasis is a frequent pathology, unfortunately when its endoscopic management fails, there is no consensus of how it should be addressed. The aim of this study was to evaluate the safety, feasibility, and long-term outcomes of laparoscopic common bile duct exploration (LCBDE) using electrosurgery (coagulation) for choledochotomy followed by primary closure after endoscopic treatment failure. A retrospective cohort study of patients who underwent LCBDE from 2013 to 2018 was conducted in Bogotá, Colombia.

Predicting mortality in penetrating cardiac trauma in developing countries through a new classification: Validation of the Bogotá classification.

Introduction: Penetrating chest trauma (PCT) represents 10% of worldwide mortality, with developing countries counting as some of the most affected by high mortality rates due to cardiac trauma. Colombia is considered one of the most violent countries due to the high mortality rate associated with war and crime, hence the validation of an own classification for penetrating cardiac injuries (PCI) is mandatory.

Methods: Retrospective cross-sectional study which included adult patients with PCIs at a level 4 trauma center in Colombia, between January 2018 and April 2020.

Laparoendoscopic surgery for the treatment of gastrointestinal stromal tumors: A case series.

Introduction: Gastrointestinal stromal tumors (GISTs) are the most common mesenchymal neoplasms of the gastrointestinal tract.
