“…Pushing the sample towards the coapted tissue end prior to irradiation may avoid tissue separation during laser irradiation. A review paper published in 2004 identified 37 relevant studies of LAVA/LAVR , and we found additional 31 relevant studies published mainly after 2004 . Of these 68 studies, 26 evaluated LAVA/LAVR without stay sutures .…”

“…Current prospective studies are being performed in our laboratory. Finally, it is not possible to become familiar with alternative techniques of conventional microvascular microanastomoses such as laser [16,17]. Despite the above limitations, the simplicity, effectiveness, and low price all suggest that training with this animal model will significantly grow and develop in the near future.…”

Background Microvascular anastomosis is the cornerstone of free tissue transfers. Irrespective of the microsurgical technique that one seeks to integrate or improve, the time commitment in the laboratory is significant. After extensive previous training on several animal models, we sought to identify an animal model that circumvents the following issues: ethical rules, cost, time-consuming and expensive anesthesia, and surgical preparation of tissues required to access vessels before performing the microsurgical training, not to mention that laboratories are closed on weekends. Methods Between January 2012 and April 2012, a total of 91 earthworms were used for 150 microsurgical training exercises to simulate vascular end-to-side microanastomosis. The training sessions were divided into ten periods of 7 days. Each training session included 15 simulations of end-to-side vascular microanastomoses: larger than 1.5 mm (n = 5), between 1.0 and 1.5 mm (n = 5), and smaller than 1.0 mm (n = 5). A linear model with the main variables being the number of weeks (as a numerical covariate) and the size of the animal (as a factor) was used to determine the trend in time of anastomosis over subsequent weeks as well as the differences between the different size groups. Results The linear model shows a significant trend (p \ 0.001) in time of anastomosis in the course of the training, as well as significant differences (p \ 0.001) between the groups of animals of different sizes. For microanastomoses larger than 1.5 mm, the mean anastomosis time decreased from 19.3 ± 1.0 to 11.1 ± 0.4 min between the first and last week of training (decrease of 42.5 %). For training with smaller diameters, the results showed a decrease in execution time of 43.2 % (diameter between 1.0 and 1.5 mm) and 40.9 % (diameter \1.0 mm) between the first and last periods. The study demonstrates an improvement in the dexterity and speed of nodes execution. Conclusion The earthworm appears to be a reliable experimental model for microsurgical training of endto-side microanastomoses. Its numerous advantages are discussed here and we predict training on earthworms will significantly grow and develop in the near future.

“…We identified four clinical series using 1950-nm diode laser [16][17][18][19], which were performed after extensive animal experience [20]. This laser seems to have an ideal wavelength for microvascular anastomoses with a 150 mm penetration that matches the thickness of the vascular wall's adventitia and media [21].…”

This study followed the methods used in Preferred Reporting Items for Systematic Reviews and Meta-Analyses [4]. Eligibility criteria were specified unambiguously to ensure that studies were selected in a systematic and unbiased manner. Via PubMed, a Medline literature search was performed. Keywords used were sutureless microvascular anastomosis, vascular closure staples, laser, tissue adhesives, and Unilink. This was combined with cross-referencing from the reference lists of all recovered and relevant publications on this subject. In total, 650 publications were discovered, of which, 180 were relevant. The inclusion criteria were sutureless devices or sutureless procedures for microvascular anastomosis, English language, clinical studies, and animal research on technologies already used in clinical practice or on refinements of existing techniques. Out of the 470 articles excluded, 120 were non-animal studies or animal experimental studies with low numbers, and 350 articles were not relevant to our topic (Figure 1).

1.9 µm diode laser assisted vascular microanastomoses: Experience in 40 clinical procedures

Abstract: The success rates for reconstructive free flap surgery realized with LAMA appear excellent. Technical innovation will most likely lead to widespread use of the handpiece laser in the operating room.
