A Multiple Regression Analysis of Postoperative Complications After Body-Contouring Surgery: a Retrospective Analysis of 205 Patients : Regression Analysis of Complications.

BACKGROUND: As bariatric surgery becomes ever more popular, so does body-contouring surgery to eliminate excess skin after radical weight loss. To date, the literature has described a number of risk factors affecting the postoperative outcome. Our study aimed to define those factors more closely, focusing on abdominoplasty ("tummy tuck") patients who suffered intra- and postoperative complications. METHODS: The study collective included 205 patients over 5 years (2001-2006) who underwent dermolipectomy at our department. The mean follow-up was 5.94 years. Every abdominoplasty was performed under general anesthesia with intraoperative one-dose antibiotic. The analysis included a complete review of all medical records. Statistical analysis was performed with the R-2.5.0 Software for Windows. RESULTS: The overall rate for major complications that required operative revision and/or antibiotics was 10.2 %, including 2.9 % cases of infections. Forty-one percent had minor complications, such as seromas, hematomas, wound healing problems, and wound dehiscences. The logistic regression models demonstrated that smoking combined with the age, a BMI higher than 30 kg/m(2), and the amount of removed tissue (measured in g) lead to significantly more wound healing problems in nearly all age groups. The probability of infections correlated with later drain removal. CONCLUSIONS: Regardless of the amount of tissue removed, no main risk factor for complications could be identified. A complication-free course and good outcome can be best achieved with careful patient selection and preoperative planning.

[Is there a psychological and physiological difference between DIEP- and free TRAM-flap? A retrospective patient survey]. / Besteht ein Unterschied zwischen DIEP- und freiem TRAM-Lappen aus physiologischer und psychologischer Sicht? Eine retrospektive Patientenbefragung.

BACKGROUND: The DIEP- (Deep Inferior Epigastric Perforator) flap and the free TRAM- (Transverser Rectus Abdominis Musculocutaneous) flap are common procedures for breast reconstruction. The aim of the study was to identify a difference in the psychological and physiological patient satisfaction between DIEP- and free TRAM-flap. MATERIAL AND METHODS: To provide a homogenous group, with a stable result of the reconstruction, the collective for questioning was picked out of the years 2009 and 2010. All patients included underwent a breast reconstruction with a DIEP-flap or free TRAM-flap at our division. For evaluation we formed 2 groups: DIEP-flap group (DLG) and TRAM-flap group (TLG). After preparing the questionnaire a telephone survey was performed. For the null hypothesis we postulated that there is no difference between DLG and TLG in the patient satisfaction. RESULTS: We contacted 44 patients, 30 of them took part in our survey (15 from the DLG and 15 from the TLG). The mean BMI in the questionnaire group was 26.9 kg/m² and the mean age was 48.3 years. 2 questions (lifting heavy loads (p=0.005) and performing sit-up's (p=0.001)) show a significant difference between DLG and TLG, a benefit of the DLG could be seen. Both questions had the physiology of the rectus abdominis muscle as background. The complication rate for partial flap loss or partial necrosis was one third lower (p=0.299) in the TLG than compared to the DLG. CONCLUSION: Up to now, physicians think that the DIEP-flap seems to be the best possible procedure for breast reconstruction with belly flaps. However, numerous studies disprove the superiority in the donor site morbidity. In the literature, an advantage of the TRAM-flap is clearly visible by comparing the complication rates. Our oral interviewing also states that there is no -difference in the psychological and physiological satisfaction of the patients. We can recommend a precise patient selection if a DIEP-flap for breast reconstruction should be performed. In case of comorbidities the possibility of the safer free TRAM-flap should be considered. In the future, a comparative analysis between the DIEP-flap, free TRAM-flap and pedicled TRAM-flap should be performed, by keeping the patients satisfaction, the complication rate and the cost effectiveness in mind.

[Model aeroplanes: a not to be ignored source of complex injuries]. / Modellflug: Eine nicht zu unterschätzende Quelle für komplexe Verletzungen.

With the incidence of work-related injuries decreasing, we continue to observe an unchanged trend in leisure-related accidents. As in any other hobby, model flying devices bear the risk for accidents among builders and flyers ranging from skin lacerations to complicated and even life-threatening injuries. The fast-moving razor-sharp propeller blades predominantly cause trauma to the hands and fingers resulting in typical multiple parallel skin injuries also affecting structures deep to the dermis (e. g., tendons, vessels and nerves). The resultant clinical management involves complex reconstructive surgical procedures and prolonged rehabilitative follow-up. Improving the legal framework (e. g., warnings by the manufacturer) on the one hand, providing informative action and sensitising those affected on the other, should form a basis for an altered prevention strategy to reduce model flying device-related injuries in the future.

Use of 2-octyl cyanoacrylate together with a self-adhering mesh (Dermabond™ Prineo™) for skin closure following abdominoplasty: an open, prospective, controlled, randomized, clinical study.

BACKGROUND: Abdominoplasty is one of the most commonly performed procedures in plastic surgery. The appearance of the scar is a major factor that contributes to the aesthetic outcome of the procedure and depends largely on the technique of wound closure. The new Prineo™ wound closure system was introduced to combine the effectiveness of 2-octyl cyanoacrylate (Dermabond™) together with a self-adhering mesh. METHODS: Fifty-two women and eight men aged between 21 and 65 years who were scheduled for abdominoplasty were included in the study. The total operating times after abdominoplasty of the traditional wound closure technique and the Prineo™-type wound closure technique were compared. Furthermore, an analysis comparing the cost of the two methods was performed. Two weeks after surgery the wounds were examined and graded using the Hollander Cosmesis Scale. At the 6- and 12-month follow-ups, the aesthetic outcome of the abdominal scar was evaluated using the Vancouver Scar Scale. Twelve months after surgery, the patients were asked to answer their part of the Patient Scar Assessment Scale. RESULTS: The mean total operating time for the new skin closure system was statistically significantly shorter than that of intradermal sutures. The mean price difference per patient was 104.27 (134.79$) in favor of Prineo™. The Hollander Cosmesis Scale indicated a significantly more favorable overall result with Prineo™ at 2 weeks after surgery. The Vancouver Scar Scale demonstrated a better cosmetic outcome in favor of Prineo™ 6 and 12 months after surgery. The Patient Scar Assessment Scale scores 12 months after surgery indicated that the patients noted significantly less pain, thickness, and irregularity with Prineo™. CONCLUSION: Based on our results, we conclude that Prineo™ is a safe and effective substitute for superficial skin closure, with good cosmetic results and no increase in wound complications. The use of Prineo™ decreases operative time and cost and enhances the patient's postoperative comfort.

[Clinical experiences using the Versajet system in burns: indications and applications]. / Klinische Erfahrungen mit dem Versajet-System in der Verbrennungsbehandlung - Indikationen und Anwendungen.

Early debridement and early skin grafting are the "Gold standard" in the surgical treatment of burns. There are different debridement methods available. Concerning the treatment of burns, surgical-sharp debridement, laser ablation and hydrosurgery system are used. While in full thickness burns the sharp debridement is advisable, the Versajet shows its benefits in the treatment of partial thickness burns. Especially for debridement of difficult to treat areas - face, neck, lips, fingers, interdigital spaces, convex and concave areas the Versajet System shows its benefits. With the Versajet System, tissue excision is precise; moreover it helps to avoid the damage of viable tissue and its vascular supply.
