“…Arti cial blood vessels were selected based on the following factors: availability of the same simulation material for all participants, cost, safety, animal welfare, ease of access, and similarity to actual surgery. There are many reports on the practice of vascular anastomosis using arteries from chicken wings [1,6], and the similarity to actual human blood vessels has been discussed. However, for this study, arti cial blood vessels were select because they could serve as a better guarantee of identity than a chicken wing artery.…”

Objective: The increase in minimally invasive surgery and endovascular procedures has led to a decrease in surgical experience. This may adversely affect both surgical training and postoperative management. Since it poses no risk to a patient, simulation training may be a solution these problems. COVID-19 requires social distancing which has created a negative impact on the simulation educational environment. To date, there is only limited research examining whether skills are evaluated objectively and equally in simulation training, especially in microsurgery. The purpose of this study was to analyze the objectivity and equality of simulation evaluation results conducted in a contest format.Methods: A nationwide recruitment process was conducted to select study participants. Participants were recruited from a pool of qualified physicians with less than 10 years’ experience. In this study, the simulation procedure consisted of incising a 1 mm thick artificial blood vessel and suturing it with a 10-0 thread using a surgical microscope. To evaluate the simulation procedures, a scoring chart was developed with a maximum of 5 points each for eight different evaluation criteria. Five neurosurgical supervisors from different hospitals were asked to use this scoring chart to grade the simulation proceduresResults: Initially, we planned to have the neurosurgical supervisors score the simulation procedure by direct observation. However, due to COVID-19 some study participants were unable to attend. Thus requiring some simulation procedures to be scored by video review. A total of 14 trainees participated in the study. The Cronbach's alpha coefficient among the scorers was 0.99, indicating a strong correlation. There was no statistically significant difference between the scores from the video review and direct observation judgments. There was a statistically significant difference (p < 0.001) between the scores for some criteria. For the eight criteria, individual scorers assigned scores in a consistent pattern. However, this pattern differed between scorers indicating that some scorers were more lenient than others.Conclusions: The results of this study indicate that both video review and direct observation methods are useful and highly objective techniques evaluate simulation procedures. Despite differences in score assignment patterns between individual scorers.

“…Practice in various training models will give you practical skills, confidence and allow you to reduce your trial errors. From using synthetic models to small rat vessels, training will allow you to practice a wide variety of techniques and help you achieve the proficiency you need to have a successful outcome . When insetting the flap, replanting the distal finger or closing a wound after LVA, one must anticipate the postoperative swelling and ensure that swelling will not increase tension to the anastomosis site.…”

Supermicrosurgery is defined as microsurgery in less than 0.8 mm vessels. It is an evolved form of microsurgery but with the same principle: (1) enhanced working environment including microscopes and finer instruments; (2) detailed preoperative evaluation and planning; (3) supermicrosurgical technique; and (4) postoperative care.Supermicrosurgery now provides reconstructive solutions to address lymphedema, distal finger amputations, allows minimal invasive reconstruction using a perforator to perforator approach, and will eventually allow targeted customized reconstruction.application of supermicrosurgery, lymphedema, oncologic reconstruction, perforator to perforator supermicrosurgery, supermicrosurgery

“…The use of nonliving models has become the most widespread alternative for training and the chicken wing seems to be the preferred choice for training in small vessels (Hayashi et al, 2018;Rodriguez, Yañez, Cifuentes, Varas, & Dagnino, 2016). Nevertheless, search for vessels under 0.3 mm can be tedious and time-consuming.…”
