International Residents' Perspectives on Education and Challenges in Microsurgery Training.

Objective Microsurgery remains an integral component of the surgical skillset and is essential for a diversity of reconstructive procedures. The apprenticeship also requires overcoming a steep learning curve, among many challenges. The method of microsurgical training differs depending on the countries' regions and resources of their health care system. Methods The Journal of Hand and Microsurgery leadership held an international webinar on June 19, 2021, consisting of a panel of residents from 10 countries and moderated by eminent panelists. This inaugural event aimed to share different experiences of microsurgery training on a global scale, identifying challenges to accessing and delivering training. Results Residents shared various structures and modes of microsurgical education worldwide. Areas of discussion also included microsurgical laboratory training, simulation training, knowledge sharing, burnout among trainees, and challenges for female residents in microsurgical training. Conclusion Microsurgical proficiency is attained through deliberate and continued practice, and there is a strong emphasis globally on training and guidance. However, much remains to be done to improve microsurgical training and start acting on the various challenges raised by residents. Level of Evidence Level V.

Leakage of ruptured silicone breast implants through abdominal laparoscopic port sites: A rare complication following transabdominoplasty breast augmentation.

BACKGROUND: Abdominoplasty and breast augmentation are two of the most commonly performed aesthetic procedures in the UK. When performed as a combined procedure, separate inframammary and abdominoplasty incisions are most frequently used. Transabdominoplasty breast augmentation, performed via a single abdominoplasty incision is also described. CASE: A 69-year-old female, having undergone a transabdominoplasty breast augmentation 20 years previously, was diagnosed with ascending colon cancer and admitted for a laparoscopic-assisted, right hemi-colectomy. Despite all the port sites being abdominal and below the inframammary fold, on their removal, silicone from ruptured breast implants was leaking through the port sites. OUTCOME: The patient subsequently underwent an uneventful explantation of bilateral, ruptured, subglandular implants and recovered well. LEARNING POINTS: We recommend that breast implant explantation should be considered when patients indicated for elective intra-abdominal surgery are noted to have ruptured breast implants on staging CT imaging, especially when inserted via an abdominoplasty approach.

International microsurgery simulation society (IMSS) consensus statement on the minimum standards for a basic microsurgery course, requirements for a microsurgical anastomosis global rating scale and minimum thresholds for training.

INTRODUCTION: Microsurgery is a surgical technique that uses optical magnification as well as specific instruments to address necessary reconstructive procedures in different medical specialties. The apprenticeship of this technique requires overcoming a steep learning curve. There is a need for standardization of the training criteria in microsurgery. The International Microsurgery Simulation Society (IMSS) was born in 2011, since then its main objective has been to connect the main international specialists and educators of this sub-specialty to share and discuss the ethical and scientific basis of preclinical microsurgery teaching. METHODS: In order to achieve a consensus on the minimum standards for the organization of basic microsurgery training courses, the requirements for a microsurgical anastomosis global rating scale and minimum thresholds for training, a total of nineteen independent global experts participated in a formal consultative consensus development program. The agreement criteria for each statement was established when consensus of 65-100% was reached. RESULTS: There have been established six recommendations concerning minimum standards for a basic microsurgery course, one recommendation in relation to minimum thresholds for training and four recommendations regarding the global rating scale as gold standard for a microsurgical anastomosis assessment. The eleven defined recommendations reached the agreement threshold of 65-100%. CONCLUSIONS: The development of this consensus sets the minimum recommended requirements for conducting basic microsurgery training courses, as well as suggestions for objective assessment of the learning curve and skills of trainees.

Osteocutaneous flaps for head and neck reconstruction: A focused evaluation of donor site morbidity and patient reported outcome measures in different reconstruction options.

With significant improvements in success rates for free flap reconstruction of the head and neck, attention has turned to donor site morbidity associated with osteocutaneous free flaps. In this review, we address the morbidity associated with harvest of the four most commonly used osteocutaneous flaps; the free fibula flap, the scapula flap, the iliac crest flap and the radial forearm flap. A comprehensive literature search was performed to identify articles relevant to donor site morbidity for these flaps. We assessed morbidity in terms of incidence of delayed healing, chronic pain, aesthetic outcomes, site specific complications and patient satisfaction/quality of life. Weighted means were calculated when sufficient studies were available for review. The radial forearm and free fibula flaps are associated with high rates of delayed healing of approximately 20% compared to the scapular (<10%) and iliac flaps (5%). The radial forearm flap has higher rates of chronic pain (16.7%) and dissatisfaction with scar appearance (33%). For the majority of these patients harvest of one of these four osteocutaneous does not limit daily function at long-term follow-up. The scapular osteocutaneous flap is associated with the lowest relative morbidity and should be strongly considered when the recipient defect allows. The radial forearm is associated with higher morbidity in terms of scarring, fractures, chronic pain and wrist function and should not be considered as first choice when other flap options are available.

Towards standardization of training and practice of reconstructive microsurgery: an evidence-based recommendation for anastomosis thrombosis prophylaxis.

BACKGROUND: Despite significant improvements in survival rates, free flap failures still occur even in experienced hands and are most commonly due to arterial or venous thrombosis. In the absence of an evidence-based guideline on the prevention of thrombosis, we reviewed the literature to assess the evidence base for commonly used interventions aimed at its prevention. METHODS: A comprehensive literature search was performed using the following keywords "free flap" and microsurgery with "pre-operative screening," "prevention of thrombosis," "ketorolac," "heparin," "low molecular weight heparin," "aspirin," "dextran," and "statins." RESULTS: Thirteen clinical studies were included in this review. No high-level evidence is available to support any perioperative or postoperative interventions aimed at reducing the risk of flap thrombosis. CONCLUSIONS: Higher level studies are needed to investigate the clinical use of antithrombotic medications in microsurgery; however, given the small failure rates in modern practice, these will need to be large multicenter trials in order to reach sufficient power.Level of Evidence: Level III, risk/prognostic study.

Bilateral patellar tendon rupture associated with statin use.

Patellar tendon rupture is an uncommon clinical presentation, which generally affects the under 40s who are active in sport. Bilateral rupture of both tendons is much rarer. It occurs most frequently in patients with predisposing factors such as corticosteroid use or systemic diseases. The authors present the case of a 56-year-old male on long-term statin therapy who sustained this injury following a fall on ice. He had no known risk factors for tendon rupture. Surgical treatment involved tendon repair using Krakow suture via bony tunnels in the patella. Statins have previously been associated with tendon ruptures at other sites but there have been no published cases of bilateral patellar tendon rupture linked to statin use. We review the literature regarding the association between statins and tendon rupture.

Randomized controlled trial testing the effects of weight loss on nonalcoholic steatohepatitis.

UNLABELLED: Nonalcoholic steatohepatitis (NASH) is a chronic progressive liver disease that is strongly associated with obesity. Currently, there is no approved therapy for NASH. Weight reduction is typically recommended, but efficacy data are lacking. We performed a randomized controlled trial to examine the effects of lifestyle intervention using a combination of diet, exercise, and behavior modification, with a goal of 7% to 10% weight reduction, on clinical parameters of NASH. The primary outcome measure was the change in NASH histological activity score (NAS) after 48 weeks of intervention. Thirty-one overweight or obese individuals (body mass index [BMI], 25-40 kg/m(2)) with biopsy-proven NASH were randomized in a 2:1 ratio to receive intensive lifestyle intervention (LS) or structured education (control). After 48 weeks of intervention, participants assigned to LS lost an average of 9.3% of their weight versus 0.2% in the control group (P = 0.003). A higher proportion of participants in the LS group had a reduction of NAS of at least 3 points or had posttreatment NAS of 2 or less as compared with the control group (72% versus 30%, P = 0.03). NAS improved significantly in the LS group (from 4.4 to 2.0) in comparison with the control group (from 4.9 to 3.5) (P = 0.05). Percent weight reduction correlated significantly with improvement in NAS (r = 0.497, P = 0.007). Participants who achieved the study weight loss goal (>or=7%), compared with those who lost less than 7%, had significant improvements in steatosis (-1.36 versus -0.41, P < 0.001), lobular inflammation (-0.82 versus -0.24, P = 0.03), ballooning injury (-1.27 versus -0.53, P = 0.03) and NAS (-3.45 versus -1.18, P < 0.001). CONCLUSION: Weight reduction achieved through lifestyle intervention leads to improvements in liver histology in NASH.
