Background: Nonoperative management of rectal cancer in patients who achieve near-complete response following total neoadjuvant therapy remains controversial and understudied.
Methods: This retrospective cohort study conducted at a tertiary National Cancer Institute-designated cancer center included patients with rectal cancer who initiated active surveillance after achieving near-complete response following induction radiotherapy and consolidation chemotherapy. Near-complete response was determined based on restaging endoluminal evaluation and pelvic magnetic resonance imaging.
Objective: Identify changes in general surgery resident autonomy and resident postgraduate year (PGY) level in Entrustable Professional Activity (EPA) cases over time.
Design: Retrospective cohort study.
Setting: United States Veterans Affairs (VA) hospital system, 2004 to 2020.
Article Synopsis
- The study aimed to gather validity evidence for the Anastomosis Objective Structured Assessment of Technical Skills (A-OSATS) tool, designed to assess the performance of a specific surgical procedure (bowel anastomosis) in surgery residents.
- Residents conducted simulated surgeries on an ex vivo pig model, were evaluated using A-OSATS, and underwent a leak test on their work to measure performance.
- Results showed that more experienced residents (PGY-5s) scored significantly higher and completed tasks faster than PGY-4s, indicating the A-OSATS tool is reliable for assessing surgical skills, though further improvements are needed before its use in critical evaluations.
Objective: Simulation training for minimally invasive colorectal procedures is in developing stages. This study aims to assess the impact of simulation on procedural knowledge and simulated performance in laparoscopic low anterior resection (LLAR) and robotic right colectomy (RRC).
Design: LLAR and RRC simulation procedures were designed using human cadaveric models.
