Endoscopic resection for subepithelial lesions-pure endoscopic full-thickness resection and submucosal tunneling endoscopic resection.

Endoscopic full-thickness resection (EFTR) and submucosal tunneling endoscopic resection (STER) are the frontier of therapeutic endoscopic. These two methods rely on the skillset and equipment of endoscopic submucosal dissection (ESD) while going beyond the boundaries of the gastrointestinal lumen. They are both representatives of natural orifice transluminal endoscopic surgery, with STER being a direct off-shoot of peroral endoscopic myotomy (POEM). Both techniques are designed for the removal of gastrointestinal tumors originating from the muscularis propria but tend to be used in different organs and come with respective challenges. In this review we will go over the history, indication, technique and literature of these two techniques.

Regenerative Wound Surgery: Practical Application of Regenerative Medicine in the OR.

Chronic nonhealing wounds cause significant morbidity and mortality and remain a challenging condition to treat. Regenerative wound surgery involves operative debridement of wounds to remove dead and healing-impaired tissue and bacterial contamination and, subsequently, the application of regenerative medicine treatments to accelerate healing. Regenerative treatments aim to restore native tissue structure and function by targeting biological mechanisms underlying impaired healing. A wide range of regenerative modalities are used for treating chronic and complex wounds, including decellularized scaffolds, living engineered donor tissues, autologous stem cells, and recombinant growth factors. Each of these modalities has specific and sometimes complex requirements for implementation. The advanced wound care team, including OR staff members, should be aware of how these products are used and regulated. This article highlights some of the common and emerging regenerative treatments that are applied in wound surgery and focuses on how the products are used practically in the OR.

A Framework to Assist Providers in the Management of Patients with Chronic, Nonhealing Wounds.

GENERAL PURPOSE: To describe the development of an evidence-based wound electronic medical record (WEMR) framework for providers to execute timely, protocol-based, best-practice care for patients with chronic, nonhealing wounds. TARGET AUDIENCE: This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care. LEARNING OBJECTIVES/OUTCOMES: After completing this continuing education activity, you should be better able to: ABSTRACT: The care of patients with nonhealing wounds involves a host of treatment modalities. The authors developed a wound-specific framework to enhance provider management of these wounds and a summary sheet to involve patients and caregivers in their own healthcare to improve treatment adherence and outcomes. Implementing evidence-based practice for chronic wounds enables corrective actions to optimize care.

Practical Application of Granulocyte-Macrophage Colony-Stimulating Factor (GM-CSF) in Patients with Wounds.

Rapidly evolving advances in wound-care technologies and treatment modalities, including locally injectable granulocyte-macrophage colony-stimulating factor (GM-CSF), are increasingly being used. Based on its role in the stimulation and recruitment of key contributors to wound healing, such as keratinocytes, macrophages, and fibroblasts, GM-CSF is considered to play an essential role in the wound-healing cascade. Synthetic GM-CSF has been shown to have a positive effect on the healing of chronic wounds when given as a local injection in a small number of patients. Subsequent randomized, controlled trials demonstrated that GM-CSF accelerated the healing of chronic wounds. This paper reviews the proposed mechanism of action of GM-CSF in wound healing. We also describe its method of application in the operating room at a tertiary care center for patients with wounds. Key Messages: Many types of chronic wounds have an altered keratinocyte and macrophage function that can be potentially assuaged by the addition of locally injected growth factor therapy to standard-of-care treatment. Granulocyte-macrophage colony-stimulating factor (GM-CSF) has been shown to be beneficial for the treatment of chronic, non-healing wounds. This article reviews the data on GM-CSF, reports a proposed mechanism of action, and describes its use by a team of wound surgeons.

Wound Care Center of Excellence: A Process for Continuous Monitoring and Improvement of Wound Care Quality.

GENERAL PURPOSE: To provide information about a study using a new process for continuous monitoring to improve chronic wound care quality.This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care.After completing this continuing education activity, you should be better able to:1. Recognize problems associated with chronic wound care.2. Identify methods used in this project to improve care.3. Illustrate the findings from this and similar projects and implications for providing improved wound care.Patients with chronic wounds require complex care because of comorbidities that can affect healing. Therefore, the goal of this project was to develop a system of reviewing all hospitalized patients seen by the study authors' wound care service on a weekly basis to decrease readmissions, morbidity, and mortality. Weekly multidisciplinary conferences were conducted to evaluate patient data and systematically assess for adherence to wound care protocols, as well as to create and modify patient care plans. This review of pathology and the performance of root-cause analyses often led to improved patient care.

A Perioperative Approach to Increase Limb Salvage When Treating Foot Ulcers in Patients With Diabetes.

Foot ulceration in patients with diabetes increases the risk of lower extremity amputation. Major amputations produce substantial adverse consequences, increase length of hospital stay, diminish quality of life, and increase mortality. In this article, we describe approaches that decrease amputations and improve the quality of life for patients with diabetes and foot ulcers. We highlight the role of the perioperative nurse, who is essential to providing optimal patient care in the perioperative period. Perioperative care of patients with diabetes involves providing optimal surveillance for a break in the skin of the foot, screening for neuropathy, following guidelines for foot ulcer infections, preparing for pathophysiology-based debridement, using adjuvant therapies, and offloading the patient's affected foot. Nurses should understand the disease process and pathophysiology and how to use these approaches in the perioperative setting to assist in curtailing the morbidity and mortality associated with foot ulcers in patients with diabetes.

The Future of Data-Driven Wound Care.

Care for patients with chronic wounds can be complex, and the chances of poor outcomes are high if wound care is not optimized through evidence-based protocols. Tracking and managing every variable and comorbidity in patients with wounds is difficult despite the increasing use of wound-specific electronic medical records. Harnessing the power of big data analytics to help nurses and physicians provide optimized care based on the care provided to millions of patients can result in better outcomes. Numerous applications of machine learning toward workflow improvements, inpatient monitoring, outpatient communication, and hospital operations can improve overall efficiency and efficacy of care delivery in and out of the hospital, while reducing adverse events and complications. This article provides an overview of the application of big data analytics and machine learning in health care, highlights important recent advances, and discusses how these technologies may revolutionize advanced wound care.

Protocol for Psychopharmacologic Management of Behavioral Health Comorbidity in Adult Patients with Diabetes and Soft Tissue Infections in a Tertiary Care Hospital Setting.

GENERAL PURPOSE: To provide information about the effect of psychiatric comorbidities on wound healing in patients with diabetes mellitus (DM). TARGET AUDIENCE: This continuing education activity is intended for physicians, physician assistants, nurse practitioners, and nurses with an interest in skin and wound care. LEARNING OBJECTIVES/OUTCOMES: After participating in this educational activity, the participant should be better able to:1. Discuss the connection between DM and the development of psychiatric comorbidities.2. Identify the drugs recommended in the treatment of these psychiatric comorbidities.3. List cautions and contraindications related to the drugs discussed. ABSTRACT: In patients with diabetes mellitus type 2, psychiatric comorbidities such as depressive and anxiety disorders are 60% or more prevalent than in the general population. The severity of mental illness and the duration of diabetes have been shown to correlate with worsening glycemic control, thus impeding wound healing. A retrospective chart review was conducted in all patients with diabetes mellitus admitted to the wound service with prior or current psychiatric symptoms of anxiety, depression, or cognitive impairment. A psychopharmacologic protocol was developed based on the clinical data collected and treatment parameters used by the behavioral health consultation liaison service.

Major Histopathologic Diagnoses of Chronic Wounds.

PURPOSE: To clarify the histopathology of acute osteomyelitis, chronic osteomyelitis, primary vasculitis, and secondary-type vasculitis. TARGET AUDIENCE: This continuing education activity is intended for physicians and nurses with an interest in skin and wound care. OBJECTIVES/OUTCOMES: After participating in this educational activity, the participant should be better able to:1. Describe the parameters and significance of this study.2. Identify chronic wound diagnosis and treatment.3. Differentiate the histopathology of osteomyelitis and vasculitis. OBJECTIVE: The presence of a chronic wound can result in significant morbidity/mortality. Understanding the pathological alterations of wound tissue that are refractory to standard wound therapy is essential for effective wound management and healing. The authors describe 4 wound etiologies, specifically, acute osteomyelitis, chronic osteomyelitis, primary vasculitis, and secondary-type vasculitis. SETTING: A tertiary care hospital. DESIGN: A retrospective review of 1392 wound operations performed during a 24-month period at a tertiary care hospital was conducted. Tissue specimens reviewed included soft tissue infections of the lower extremity, sacrum, hip/pelvis, trunk, perineum, and buttocks. MAIN RESULTS: Acute osteomyelitis is defined as bone tissue with a predominance of polymorphonuclear leukocytes, evidence of osteoclast bone resorption with scalloping of the cortical bone edges, and bone detritus. Chronic osteomyelitis is defined as bone tissue with a significant amount of fibrosis surrounding devitalized tissue and heavy infiltration of lymphocytes and plasma cells. Primary-type vasculitis is defined primarily as inflammation and necrosis of blood vessel walls. In cutaneous lesions of granulomatosis with polyangiitis, ulceration with numerous inflammatory granulomas is seen in the papillary dermis. Secondary vasculitis is defined by vessel wall infiltration by inflammatory cells and fibrinoid necrosis of the small vessel wall. CONCLUSIONS: Pathologies of these 4 types of wounds can complicate standard algorithms designed for diagnosis and treatment, and accurate diagnosis through histopathologic analysis can help tailor targeted treatment.
