Panniculectomy Performed in Conjunction with Gynecologic Surgery in the Morbidly Obese Patient - a NSQIP Analysis and Meta-Analysis of the Literature

Purpose: Panniculectomy is a common procedure in plastic surgery, often performed following massive weight loss and in morbidly obese patients. It can be performed in combination with various gynecologic procedures based on the rational that it will reduce complication rates.1, 2, 3 These studies fail to provide proof of these claims for reasons including study design and the lack of inclusion of both morbidly obese and non-morbidly obese patients. Recent medical practice has focused increasingly on minimizing patient morbidity and trends in reimbursement are moving towards penalizing practices which increase complications. Methods/Results:We reviewed the NSQIP database to assess the association of complications with panniculectomy combined with gynecologic surgery. The query identified 296 patients with a BMI \u3e 30 who had panniculectomy concomitant with gynecologic surgery. The results demonstrated a statistically significant relationship (P Our review of NSQIP and the existing literature does not support the premise that there is a statistically significant benefit to patients of performing panniculectomy in conjunction with gynecologic surgery in the morbidly obese patient population. In the light of the risks to patients and current direction of medical practice the addition of elective panniculectomy to gynecologic surgery should be re-considered in the morbidly obese patient population

A modified heterotopic swine hind limb transplant model for translational vascularized composite allotransplantation (VCA) research.

Vascularized Composite Allotransplantation (VCA) such as hand and face transplants represent a viable treatment option for complex musculoskeletal trauma and devastating tissue loss. Despite favorable and highly encouraging early and intermediate functional outcomes, rejection of the highly immunogenic skin component of a VCA and potential adverse effects of chronic multi-drug immunosuppression continue to hamper widespread clinical application of VCA. Therefore, research in this novel field needs to focus on translational studies related to unique immunologic features of VCA and to develop novel immunomodulatory strategies for immunomodulation and tolerance induction following VCA without the need for long term immunosuppression. This article describes a reliable and reproducible translational large animal model of VCA that is comprised of an osteomyocutaneous flap in a MHC-defined swine heterotopic hind limb allotransplantation. Briefly, a well-vascularized skin paddle is identified in the anteromedial thigh region using near infrared laser angiography. The underlying muscles, knee joint, distal femur, and proximal tibia are harvested on a femoral vascular pedicle. This allograft can be considered both a VCA and a vascularized bone marrow transplant with its unique immune privileged features. The graft is transplanted to a subcutaneous abdominal pocket in the recipient animal with a skin component exteriorized to the dorsolateral region for immune monitoring. Three surgical teams work simultaneously in a well-coordinated manner to reduce anesthesia and ischemia times, thereby improving efficiency of this model and reducing potential confounders in experimental protocols. This model serves as the groundwork for future therapeutic strategies aimed at reducing and potentially eliminating the need for chronic multi-drug immunosuppression in VCA
