Brazil-TNT: A Randomized Phase 2 Trial of Neoadjuvant Chemoradiation Followed by FOLFIRINOX Versus Chemoradiation for Stage II/III Rectal Cancer.

Background: Neoadjuvant radiation and oxaliplatin-based systemic therapy (total neoadjuvant therapy-TNT) have been shown to increase response and organ-preservation rates in localized rectal cancer. However, trials have been heterogeneous regarding treatment protocols and few have used a watch-and-wait (WW) approach for complete responders. This trial evaluates if conventional long-term chemoradiation followed by consolidation of FOLFIRINOX increases complete response rates and the number of patients managed by WW.

Robot-assisted transanal minimally invasive surgery for the treatment of rectal adenocarcinoma.

This is a video vignette of a 57-year-old asymptomatic female patient. The patient underwent a screening colonoscopy which revealed a 10 mm scar in the rectum. Biopsy resulted in a well-differentiated tubular adenocarcinoma.

Does Tri-Staple™ technology reduce the risk of anastomotic leakage in colorectal surgery? A propensity score matching analysis.

Background And Objectives: This study evaluates the Tri-Staple™ technology in colorectal anastomosis.

Methods: Patients who underwent rectosigmoidectomy between 2016 and 2022 were retrospectively evaluated and divided into two groups: EEA™ (EEA) or Tri-Staple™ (Tri-EEA). The groups were matched for age, sex, American Society of Anesthesiologists (ASA), and neoadjuvant radiotherapy using propensity score matching (PSM).

Implementation of the Fast-track Protocol for Total Hip Arthroplasty in a Public Hospital in the State of São Paulo - Brazil.

 Evaluate the results of the implementation of the Fast Track Protocol (FTP), a medical practice based on scientific evidence, for elective total hip arthroplasty surgery, mainly comparing the National Average Hospital Admission Rate of 7.1 days.  98 patients who underwent elective total hip arthroplasty surgery via the direct anterior approach, anterolateral approach and posterior approach were included in the FTP from December 2018 to March 2020, being followed up preoperatively, intraoperatively and immediately postoperatively.
