Retrospective analysis in lower limb reconstruction : propeller perforator flaps versus free flaps
Background: Technical advancements and increasing experience in the management of soft tissue defects in lower extremities have led to the evolution of decisional reconstructive algorithms. Both propeller perforator flaps (PPFs) and free flaps (FFs) proved to be useful methods of reconstruction for lower extremities defects, offering alternative reconstructive tools. We present a case series of PPFs and FFs for reconstruction of lower limbs defects, analyzing and comparing treatment and outcomes.
Methods: Through a retrospective analysis, we report our experience in performing PPFs or FFs for reconstruction of soft tissue defects of the lower extremities, in patients admitted between 2010 and 2015 at the Department of Plastic and Reconstructive Surgery, University of Palermo. In these patients, we evaluated location and causes of defects, types of flaps used, recipient vessels, complications, time to healing, and aesthetic outcome.
Results: A primary healing rate was obtained in 13 patients for PPF and 16 cases for FF. Revision surgery for partial skin necrosis was required in eight cases (PPF: four and FF: four). Recovery time and hospitalization period were eventually shorter in patients with FFs, due to lower rate of complications and revision surgery.
Conclusion: In the past years, our indications for reconstruction with PPFs in the lower limb have become more restricted, while we favor reconstruction with FFs. Recommendations are provided to orient surgical treatment in small, medium, and large lower limb defects
Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study
Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.

Fournier’s gangrene secondary to male’s circumcision – a case report and review of the literature
Background: Fournier's gangrene is necrotizing fasciitis of the genitalia, perineal and perianal region associated with a significant mortality rate. The potentially fatal disease is caused both by aerobic and anaerobic bacteria and primarily occurs in men. The majority of Fournier's gangrene cases is idiopathic or derived from perineal and genital skin infections. Early surgical debridement of necrotic tissues and antibiotics are fundamental. Case: We report a rare case of Fourniers gangrene of a 57-year-old man secondary to circumcision. The patient presented due to painful swelling of the scrotum and perineum associated with high-grade fever. The patient received broad-spectrum antibiotics and underwent immediate surgical debridement; a total of five other debridements were performed during the recovery until the wounds healed. On a second recovery phase, we performed a penile reconstruction with full thickness skin graft with satisfactory cosmetic and functional results. Conclusion: FG remains an urgent condition associated with a high mortality rate, requiring immediate treatment. More statistical reports and standard guidelines are necessary to improve the rate of its survival
Malattia di Dupuytren
La malattia di Dupuytren ancora oggi rimane avvolta nel mistero: è incerta la paternità della sua prima descrizione, sebbene, e con molte polemiche, da centoottantuno anni è storicamente legata all’illustre chirurgo francese Guillaume Dupuytren. Un enigma per gli studiosi è anche la sua eziopatogenesi, in cui fattori ambientali, comportamentali, genetici, e biomolecolari, in parte ancora sconosciuti, interagiscono a più livelli, generando reazioni biochimiche a cascata che portano alla ben nota iperproliferazione dei fibroblasti e alla conseguente deposizione di collagene. Essa rappresenta inoltre una sfida per il chirurgo che deve districarsi tra tecniche operatorie differenti in relazione allo stadio della malattia, età del paziente, esigenze di vita quotidiana, in un distretto che per complessità anatomica non ha eguali nel resto del corpo. Fino ad ora la chirurgia è stata la sola opzione terapeutica codificata che abbia permesso di ottenere la correzione delle deformità digitali a lungo termine. Risultati incoraggianti sono stati raggiunti di recente con la collagenasi, di cui ancora non esistono risultati a distanza statisticamente significativi. Sono ancora necessari ulteriori studi e approfondimenti che richiedono contributi e collaborazioni tra i “diversi campi del sapere? al fine di trovare soluzioni sempre meno invasive per la cura definitiva di questa malattia
A propeller flap for single-stage nose reconstruction in selected patients: supratrochlear artery axial propeller flap
The paramedian forehead flap is the gold standard technique for nose reconstruction. It requires two different surgical operations which prolonged the postoperative dressing and care. We present our 5-year experience with a propeller flap based on the supratrochlear artery, which allows one-stage transfer of the forehead skin to the nose without the need for pedicle division. This technique is indicated in a selected group of patients who are not suitable for multiple-stage reconstructions because they have concurrent medical conditions, reduced mobility, or live far away from specialized medical centers. We have renamed this procedure as supratrochlear artery axial propeller flap, from the acronym STAAP flap, to stress the axial, well known and constant, vascularization of the flap. In the past 5 years, we have been performing 25 STAAP flaps; full-thickness nasal reconstruction was performed in 11 cases. The patients were 16 males and 9 females, with a mean age of 79.5 years. All patients had multiple comorbidities. Complete flap survival was observed in 23 cases and healing was complete in 7 days. In two cases, there was a partial distal necrosis of the flap treated conservatively. Cosmetic results were good and the patient's satisfaction was significant. These results indicate that the STAAP flap is a reliable and useful technique in selected cases, as old or noncompliant patients who benefit from a one-stage technique of nose reconstruction

A systematic review on external ear melanoma
Background External ear melanoma accounts for only 1% of all cutaneous melanomas, and data on its optimal management and prognosis are limited. Aim We aim to review the literature on external ear melanoma to guide surgeons in the treatment of this uncommon and peculiar pathology. Materials and methods A systematic review of English language studies on ear melanoma published from 1993 to 2013 was performed using the PubMed electronic database. Data on epidemiology, oncological treatment (tumor resection and regional lymph nodes management), and reconstruction were extrapolated from selected papers. Results The total number of patients was 858 (30 studies). The helix was the most common location (57%); superficial spreading melanoma was the most common histopathological subtype (41%). The mean Breslow thickness was 2.01 mm, with 88% of stage I-II patients. Sentinel lymph node biopsy was performed in 45% of patients, with 8% of positive nodes. Available data on its prognosis are fragmentary and contrasting, but the Breslow thickness appears to be the main prognostic factor. There is a tendency towards reduced resection margins and preservation of the underlying perichondrium and cartilage. Local flaps are the most popular reconstructive option. Conclusion To the best of our knowledge, this systematic review presents the largest data series on external ear melanoma. There is no general agreement on its surgical management, but a favorable prognosis seems to justify the tendency towards conservative treatments
Effects of pre-operative isolation on postoperative pulmonary complications after elective surgery: an international prospective cohort study
We aimed to determine the impact of pre-operative isolation on postoperative pulmonary complications after elective surgery during the global SARS-CoV-2 pandemic. We performed an international prospective cohort study including patients undergoing elective surgery in October 2020. Isolation was defined as the period before surgery during which patients did not leave their house or receive visitors from outside their household. The primary outcome was postoperative pulmonary complications, adjusted in multivariable models for measured confounders. Pre-defined sub-group analyses were performed for the primary outcome. A total of 96,454 patients from 114 countries were included and overall, 26,948 (27.9%) patients isolated before surgery. Postoperative pulmonary complications were recorded in 1947 (2.0%) patients of which 227 (11.7%) were associated with SARS-CoV-2 infection. Patients who isolated pre-operatively were older, had more respiratory comorbidities and were more commonly from areas of high SARS-CoV-2 incidence and high-income countries. Although the overall rates of postoperative pulmonary complications were similar in those that isolated and those that did not (2.1% vs 2.0%, respectively), isolation was associated with higher rates of postoperative pulmonary complications after adjustment (adjusted OR 1.20, 95%CI 1.05-1.36, p = 0.005). Sensitivity analyses revealed no further differences when patients were categorised by: pre-operative testing; use of COVID-19-free pathways; or community SARS-CoV-2 prevalence. The rate of postoperative pulmonary complications increased with periods of isolation longer than 3 days, with an OR (95%CI) at 4-7 days or >= 8 days of 1.25 (1.04-1.48), p = 0.015 and 1.31 (1.11-1.55), p = 0.001, respectively. Isolation before elective surgery might be associated with a small but clinically important increased risk of postoperative pulmonary complications. Longer periods of isolation showed no reduction in the risk of postoperative pulmonary complications. These findings have significant implications for global provision of elective surgical care
