Background Medical education has traditionally relied on in-person-based curriculums in medical school and residency . However, due to the COVID19 pandemic, medical schools and residency programs have been forced to rapidly transition to virtual platforms for learning. Surgical education poses a particular challenge, as virtual platforms cannot adequately replace hands-on learning of surgical skills. In this review, we will discuss the various ways in which virtual learning has been employed in surgical education and how it may be used to enhance learning of medical students and residents in the future. Methods We conducted a comprehensive literature search to identify articles published regarding medical school and surgical residency curriculum changes after COVID19. Results Over the past year, several surgery departments have piloted programs using virtual learning modules, live online lectures and training workshops, and remote streaming into the OR to supplement more traditional in-person learning. Overall, these programs have received positive feedback from participating medical students and residents, suggesting that virtual and online tools may be helpful in supplementing surgical education. However, several programs also noted the possibility for significant disparities in learning due to variable access to internet and availability of newer technologies. Conclusion Going forward, distance learning will play an important role in surgical education to further enhance learning of medical students and residents in a field with rapid technological advancements.

A Minimally Invasive Limited Ligation Endoluminal-assisted Revision (MILLER) banding procedure has been used for treating patients with dialysis access–related steal syndrome (DASS) and high-flow vascular access–related pulmonary hypertension (PHT) and heart failure (HF). We performed a retrospective analysis of patients undergoing the MILLER procedure performed for DASS, HF, and PHT from our Vascular Access Database from September 2017 to October 2019. Outcomes included primary patency of banding, primary assisted patency, and secondary patency, using time-to-event analyses with Kaplan-Meier curves and life tables to estimate 6- and 12-month rates. A total of 13 patients (6 men and 7 women, mean age 60 ± 14 years) underwent the MILLER procedure, 6 patients for DASS and 7 patients for pulmonary hypertension and heart failure (PHT/HF). Technical success was achieved in all patients. The longest duration of follow-up was 28 months (median 12 months [IQR 7, 19]). One patient died at 1 month after the intervention due to stroke. One patient developed access thrombosis of the graft 3 days after the procedure. Repeat banding was required in 1 patient 8 months after the first procedure. The 6-month primary patency rate of banding following this procedure was 83% while the 12-month rate was 66%. The 6- and 12-month secondary patency rates were 87% and 75%, respectively. The MILLER procedure can be performed for DASS and PHT/HF with improvement of symptoms and good long-term patency rates. Additional interventions to maintain patency and efficacy are required on long-term follow-up.
