Article Synopsis
- Colonoscopy has a failure rate of 3-5%, highlighting the need for ongoing training and skill development for both trainees and experienced endoscopists to enhance their performance and reduce complications.!* -
- A new hybrid colonoscopy training simulator combines physical and virtual elements to visualize pressure applied during procedures, providing quantitative feedback to improve skills among 33 study participants, including both trainees and experts.!* -
- Results show that trainees apply significantly higher pressure than experts, especially in the recto-sigmoid area, demonstrating the simulator's effectiveness as a learning tool, with participants agreeing on its usability and potential impact on training programs.!*
Article Synopsis
- The study investigates how the designation of bariatric centers impacts clinical outcomes for patients needing repeat abdominal surgery after initial bariatric procedures.
- Researchers analyzed data from 3301 Ontario residents who had primary bariatric surgeries between 2010 and 2017, focusing on complications, mortality, readmission, and hospital stay length.
- Findings indicate no significant differences in complications or mortality between designated bariatric and non-bariatric centers, though complex hernia surgeries showed better outcomes at bariatric centers.
Background: Correct identification of the surgical tissue planes of dissection is paramount at the operating room, and the needed skills seem to be improved with realistic dynamic models rather than mere still images. The objective is to assess the role of adding video prequels to still images taken from operations on the precision and accuracy of tissue plane identification using a validated simulation model, considering various levels of surgeons' experience.
Methods: A prospective observational study was conducted involving 15 surgeons distributed to three equal groups, including a consultant group [C], a senior group [S], and a junior group [J].
Background: Same-day surgery is an increasingly utilized and cost-effective strategy to manage common surgical conditions. However, many institutions limit ambulatory surgical services to only healthy individuals. There is also a paucity of data on the safety of same-day discharge among high-risk patients.

Current guidelines do not endorse age limits for surgery; however, older patients may encounter difficulties with access given perceived risks. This study compares the adjusted probability of failing to receive bariatric surgery between older (≥ 60 years) and younger (< 60 years) patients referred to a publicly funded program.

Methods: Articles published between January 2004 and January 2019 were screened. A total of 167 reports were identified in combined literature search, of which 61 articles were selected after exclusion of duplicate and unrelated articles.
Background: Esophagectomy has been the standard of care for patients with intramucosal adenocarcinoma (IMC) in the setting of Barrett's esophagus. It is, however, associated with significant post-operative morbidity and mortality. Endoscopic mucosal resection (EMR) offers a minimally invasive approach with lesser morbidity.
