Background and Objectives:Bariatric surgery has been shown to be an effective weight loss treatment for the morbidly obese, but some primary care physicians remain hesitant about postoperative treatment and management of patients who have undergone the surgery and recommend it to their obese patients infrequently. The purpose of this study was to evaluate perceptions of primary care physicians of the role of bariatric surgery in the management of obese patients and to identify possible barriers to treatment.Methods:A survey of PCPs within our institution was conducted to determine attitudes, knowledge, and practices regarding the treatment of morbidly obese patients, with a specific focus on identifying factors that influence referral patterns for bariatric surgery.Results:Among 161 eligible PCPs, 57 (35.4%) responded. Most respondents (59%) reported that at least 1 in 4 of their patients had a BMI ≥35 kg/m2. Although 39% thought that diet and exercise were an effective means of sustained weight loss, only 12% were satisfied with prescribing nonsurgical interventions. Sixty-three percent agreed that bariatric surgery is generally effective in the long term. All respondents were aware of the commonly established benefits, including improvement of diabetes, hypertension, and hyperlipidemia. In addition, 65% were familiar with the indications for bariatric surgery, and 70% felt comfortable discussing it with patients as a treatment option. Fewer than half of the respondents felt confident in providing postoperative management. Cost was a perceived limitation, with 53% reporting that most of their patients could not afford bariatric surgery.Conclusions:The general attitude of PCPs toward bariatric surgery is supportive. Physicians are largely aware of the indications and benefits; however, far fewer are comfortable in management of patients after surgery. A lack of supplemental information and concerns regarding the cost of surgery can impede treatment and referrals.

Modern advances in tissue engineering have transformed the plastic surgeon's management strategies across a wide variety of applications. Comprehension of the fundamentals of biologic constructs is critical to navigating the available armamentarium. It is essential that plastic surgeons become familiar with some of the existing methods for utilizing biologics as well as the advantages and limitations to their use. In this article, the authors describe the basic science of biologics with a focus on acellular dermal matrices (ADMs), and review the recent evidence behind their use for a variety of reconstructive and aesthetic purposes. The review is organized by system and examines the common indications, techniques, and outcomes pertaining to the application of ADMs in select anatomic areas. The final section briefly considers possible future directions for using biologics in plastic and reconstructive surgery.
Painful neuroma formation is a common and debilitating sequela of traumatic or oncologic nerve amputations. Studies suggest that isolating transected nerve stumps within protective caps during amputation surgery or revision procedures may assist in preventing symptomatic nerve-end neuroma formation. This study evaluated the local effects of two porcine small intestine submucosa (pSIS) nerve caps of differing configurations on a terminal nerve end in an animal model. The tibial nerves of 57 Sprague Dawley rats were transected and transposed to the lateral hind leg. The nerves were treated with one of three SIS materials, including (i) a nerve cap with spiraling chambering, termed spiral nerve cap (SNC), (ii) a nerve cap with bifurcated chambers termed chambered nerve cap (CNC), or (iii) an open tube. The surgical control consisted of nerve stumps that were not treated. Overall tissue response, axonal swirling, optical density of axons, and behavioral pain response were quantified at 8 and 12 weeks postoperatively. There were no notable differences between the performance of the SNC and CNC groups. The pSIS nerve caps mitigated aberrant axonal regeneration and decreased neuroma formation and associated pain response. These findings suggest that nerve caps with internal chambers for axonal outgrowth may improve axonal alignment, therefore reducing the likelihood of symptomatic neuroma formation.
