Electrical injuries represent life-threatening emergencies. Evidence on differences between high (HVI) and low voltage injuries (LVI) regarding characteristics at presentation, rhabdomyolysis markers, surgical and intensive burn care and outcomes is scarce. Consecutive patients admitted to two burn centers for electrical injuries over an 18-year period (1998–2015) were evaluated. Analysis included comparisons of HVI vs. LVI regarding demographic data, diagnostic and treatment specific variables, particularly serum creatinine kinase (CK) and myoglobin levels over the course of 4 post injury days (PID), and outcomes. Of 4075 patients, 162 patients (3.9%) with electrical injury were analyzed. A total of 82 patients (50.6%) were observed with HVI. These patients were younger, had considerably higher morbidity and mortality, and required more extensive burn surgery and more complex burn intensive care than patients with LVI. Admission CK and myoglobin levels correlated significantly with HVI, burn size, ventilator days, surgical interventions, amputation, flap surgery, renal replacement therapy, sepsis, and mortality. The highest serum levels were observed at PID 1 (myoglobin) and PID 2 (CK). In 23 patients (14.2%), cardiac arrhythmias were observed; only 4 of these arrhythmias occurred after hospital admission. The independent predictors of mortality were ventilator days (OR 1.27, 95% CI 1.06–1.51, p = 0.009), number of surgical interventions (OR 0.47, 95% CI 0.27–0.834, p = 0.010) and limb amputations (OR 14.26, 95% CI 1.26–162.1, p = 0.032). Patients with electrical injuries, HVI in particular, are at high risk for severe complications. Due to the need for highly specialized surgery and intensive care, treatment should be reserved to burn units. Serum myoglobin and CK levels reflect the severity of injury and may predict a more complex clinical course. Routine cardiac monitoring > 24 h post injury does not seem to be necessary.

Background: Tracheoesophageal fistulae (TEF) after oncologic resections and multimodal treatment are life-threatening and surgically challenging. Radiation and prior procedures hamper wound healing and lead to high complication rates. We present an interdisciplinary algorithm for the treatment of TEF derived from the therapy of consecutive patients. Patients and methods: 18 patients (3 females, 15 males) treated for TEF from January 2015 to July 2017 were included. Two patients were treated palliatively, whereas reconstructions were attempted in 16 cases undergoing 24 procedures. Discontinuity resection and secondary gastric pull-up were performed in two patients. Pedicled reconstructions were pectoralis major (n = 2), sternocleidomastoid muscle (n = 2), latissimus dorsi (n = 1) or intercostal muscle (ICM, n = 7) flaps. Free flaps were anterolateral thigh (ALT, n = 4), combined anterolateral thigh/anteromedial thigh (ALT/AMT, n = 1), jejunum (n = 3) or combined ALT–jejunum flaps (n = 2). Results: Regarding all 18 patients, 11 of 16 reconstructive attempts were primarily successful (61%), whereas long-term success after multiple procedures was possible in 83% (n = 15). The 30-day survival was 89%. Derived from the experience, patients were divided into three subgroups (extrathoracic, cervicothoracic, intrathroracic TEF) and a treatment algorithm was developed. Primary reconstructions for extra- and cervicothoracic TEF were pedicled flaps, whereas free flaps were used in recurrent or persistent cases. Pedicled ICM flaps were mostly used for intrathoracic TEF. Conclusion: TEF after multimodal tumor treatment require concerted interdisciplinary efforts for successful reconstruction. We describe a differentiated reconstructive approach including multiple reconstructive techniques from pedicled to chimeric ALT/jejunum flaps. Hereby, successful reconstructions are mostly possible. However, disease and patient-specific morbidity has to be anticipated and requires further interdisciplinary management.

Microsurgical breast reconstruction demands the highest level of expertise in both reconstructive and aesthetic plastic surgery. Implementation of such a complex surgical procedure is generally associated with a learning curve defined by higher complication rates at the beginning. The aim of this study was to present an approach for teaching deep inferior epigastric artery perforator (DIEP) and transverse upper gracilis (TUG) flap breast reconstruction, which can diminish complications and provide satisfying outcomes from the beginning. DIEP and TUG flap procedures for breast reconstruction were either performed by a senior surgeon (>200 DIEP/TUG, ”no-training group”), or taught to one of five trainees (>80 breast surgeries; >50 free flaps) in a step-wise approach. The latter were either performed by the senior surgeon, and a trainee was assisting the surgery (“passive training”); by the trainee, and a senior surgeon was supervising (“active training”); or by the trainee without a senior surgeon (“after training”). Surgeries of each group were analyzed regarding OR-time, complications, and refinement procedures. A total of 95 DIEP and 93 TUG flaps were included into this study. Before the first DIEP/TUG flap without supervision, each trainee underwent a mean of 6.8 DIEP and 7.3 TUG training surgeries (p > 0.05). Outcome measures did not reveal any statistically significant differences (passive training/active training/after training/no-training: OR-time (min): DIEP: 331/351/338/304 (p > 0.05); TUG: 229/214/239/217 (p > 0.05); complications (n): DIEP: 6/13/16/11 (p > 0.05); TUG: 6/19/23/11 (p > 0.05); refinement procedures (n): DIEP:71/63/49/44 (p > 0.05); TUG: 65/41/36/56 (p > 0.05)), indicating safe and secure implementation of this step-wise training approach for microsurgical breast reconstruction in both aesthetic and reconstructive measures. Of note, despite being a perforator flap, DIEP flap required no more training than TUG flap, highlighting the importance of flap inset at the recipient site.

Die chirurgische Behandlung von Dekubitalgeschwüren ist ein herausfordernder Teil der Therapie von Haut- und Weichteildefekten. Nicht nur die Wahl der richtigen Methode, sondern auch die Selektion von Patient*innen und deren Nachbehandlung entscheiden maßgeblich über Erfolg und Misserfolg der operativen Behandlung. Eine neue Leitlinie zur Behandlung von Druckgeschwüren ist in Arbeit. Article published online: 20 November 2025 © 2025. Thieme. All rights reserved.

Introduction: Various scoring systems are applied to burn patients to assess the perioperative and mortality risks as well as comorbidities. Objective: The purpose of this study was to compare the predictive accuracies for mortality of different scoring systems: the Abbreviated Burn Severity Index (ABSI), Bogenhausen ABSI (BABSI), American Society of Anesthesiologists (ASA) classification, Charlson Comorbidity Index (CCI) and modified Frailty Index-5 (mFI-5). Materials and Methods: We retrospectively analyzed 644 burn patients treated at one burn center between September 2018 and May 2022. Results: Median scores were 5 (range: 1–16), 5 (range: 2–17.5), 2 (range: 1–5), 0 (range: 0–14) and 0 (range: 0–5) for the ABSI, BABSI, ASA, CCI and mFI-5, respectively. Significantly different median score results were observed between survivors and non-survivors: ABSI: 5 vs. 10; BABSI: 5 vs. 10.5; ASA: 2 vs. 4; CCI: 0 vs. 5; and mFI-5: 0 vs. 2 (p < 0.001 for all scores). Predictive accuracies were excellent for the BABSI (AUC = 0.963), ABSI (AUC = 0.952), and ASA (AUC = 0.916), whereas fair predictive accuracies were found for the CCI (AUC = 0.851) and mFI-5 (AUC = 0.760). Good calibration was observed for the BABSI, ABSI, CCI, and mFI-5, whereas calibration was poor for the ASA. Conclusion: All five scores significantly differentiate between survivors and non-survivors. However, the strongest discriminatory power and best calibration for mortality prediction were observed for the BABSI and ABSI scores. Therefore, the application of both scores is recommended in daily routine.
