Peroral Endoscopic Myotomy for Achalasia.

Peroral endoscopic myotomy surgery is an incisionless, minimally invasive, natural orifice technique used to treat the symptoms of achalasia and other spastic disorders of the esophagus. Recent experience demonstrates that it can be performed safely by experienced esophageal surgeons and there are very good short-term outcomes comparable to laparoscopic myotomy. The rapid worldwide adoption of this technique demonstrates its potential to replace the current therapies available for achalasia. A cautionary note is important in that long-term outcomes are not yet available in terms of dysphagia and GERD symptoms.

Technology-Enhanced Simulation Improves Trainee Readiness Transitioning to Cardiothoracic Training.

OBJECTIVE: Transitioning from medical school and general surgery training to cardiothoracic (CT) surgical training poses unique challenges for trainees and patient care. We hypothesized that participation in technology-enhanced simulation modules that provided early exposure to urgent/emergent CT patient problems would improve cognitive skills and readiness to manage common urgencies/emergencies. DESIGN: Traditional and integrated cardiothoracic residents at our institution participated in a technology-enhanced simulation curriculum. The course comprised of didactics, hands-on simulation, virtual models, and mock oral examinations. Residents also were given a validated pretest and post-test to evaluate knowledge retention and integration. Resident performance was graded using a previously validated objective structured clinical examination. Resident perception of course usefulness and relevance was determined through the completion of a perception survey. SETTING: This study occurred at the University of Pittsburgh School of Medicine with the Department of Cardiothoracic Surgery. The facility used was the Peter Winter Institute for Simulation, Education and Research. PARTICIPANTS: From 2013 to 2015, 25 traditional and integrated cardiothoracic residents participated in these training modules who have completed all portions of the simulation were used for analysis. RESULTS: For our participants, knowledge base significantly increased by 7.9% (pretest = 76.0% vs. post-test = 83.9%, p < 0.01). According to trained-rater evaluation, 93.6% of responses to the 11 objective structured clinical examination competencies were deemed adequate. Postcourse perception survey demonstrated 92% of participants scoring the sessions as important or very important toward development and confidence in managing the cardiothoracic scenarios. These findings were present despite historical assumption that these learners were prepared for complex patient care. CONCLUSIONS: After completing a technology-enhanced course combining didactics, simulation, and real-time assessment, residents demonstrated objective improvements in cognitive skills and readiness in managing CT patients. Resident postcourse feedback indicated enhanced confidence, suggesting increased preparedness transitioning to CT surgery. This has strong implications for improved patient safety during these potentially labile transition periods.

Chordal relocation for repair of anterior mitral leaflet flail: a reproducible option.

Repair of anterior mitral leaflet (AML) flail is considered to be among the more technically challenging mitral procedures. While neochord reconstruction is an excellent technique, sizing challenges may limit wide reproducibility. Chordal relocation of secondary or tertiary AML chords can minimize sizing imprecision in open or minimally invasive repair while providing patients with a safe, durable and reproducible option. Native chords can be readily released and re-implanted from positions in the body of the leaflet to provide primary AML support, provided there is preservation of ipsilateral papillary muscle alignment. We illustrate the sole use of this reproducible method to repair AML flail.
