RESUMEN

OBJECTIVE: The significance of thought differences has always held importance in medicine, but it could be considered as increasingly acknowledged and valued to a greater extent in recent times as more emphasis is placed on diversity, equity, and inclusion. These unique perspectives have been examined according to race, gender, and ethnicity, but there is limited published data examining the prevalence of leadership roles within surgical departments in terms of training background. Our main objective is to identify trends in surgical leaders' education, and emphasize training diversity in surgical leadership. DESIGN: A descriptive study of the training background of all surgical academic leaders. SETTING: This internet search was performed at a tertiary care, academic medical center. PARTICIPANTS: Academic chairpersons, division directors, and program directors. RESULTS: 124 programs had pertinent information available. There was a mean of 7.6 leaders per institute examined: total 939 positions (119 chairs, 704 division directors, 116 program directors). 90/119 (76%) of the Chairs led at institutions outside of the places they completed their training. 4/119 (3%) did all their training at the same institution they chaired. 25/119 (21%) completed at least some but not all their training there, and later rose to the role of Chair. Among division directors, 217/704 (31%) did some training at that institution, and program directors were significantly more likely to have completed some training at their current institute (53/116, 46%; p = 0.001). There were no statistically significant differences when examined geographically. Women made up 18% of the leaders and were significantly more likely to lead as program director rather than a chair or division director (p < 0.001). CONCLUSION: A majority of surgery chairs hold positions at institutions where they did not complete their medical training. This suggests that outside perspective could be a contributing factor when searching for this position.

RESUMEN

PURPOSE: Diagnosis and treatment of perianal Crohn's disease is challenging and requires its own domain of therapy. Different types of perianal disease require a spectrum of treatment strategies. Treatment options range from conservative therapy, including immunosuppressives, biologics, or stem cell therapy, to surgical treatment with specific indications depending on the underlying lesion. This is part III of the series "state-of-the-art surgery for Crohn's disease," focusing on the management of perianal disease. We discuss the definition and diagnosis of perianal Crohn's disease, the treatment of perianal lesions, and specific surgical indications and techniques. RESULTS AND CONCLUSION: Pitfalls and complications play a substantial role in the treatment of perianal Crohn's disease, and surgical therapy may fail. Realistic treatment goals and an individual patient-oriented treatment approach are crucial in the treatment of perianal Crohn's disease.

RESUMEN

Despite advances in medical therapy, surgery continues to play a vital role in the management of Crohn's disease and its complications. Continuing from Part I of this series (small intestine/ileal disease), we focus next on colonic Crohn's disease and associated neoplasms. We will first review the surgical management of medical-refractory Crohn's colitis and its complications and then examine cancer risk, surveillance, and surgical management of Crohn's-associated colorectal dysplasia and malignancy. We conclude with a discussion of restoration of gastrointestinal continuity following colonic surgery for Crohn's disease.

RESUMEN

BACKGROUND: The need to continue providing care to patients during the corona virus disease 2019 pandemic facilitated telemedicine's rapid adoption, including in surgical clinic settings. Our purpose was to evaluate integration of telemedicine into an academic colorectal surgery practice and assess physician experiences providing telemedicine care. METHODS: Patients seen in colorectal surgery clinic by telemedicine and in person from March 31, 2020 to August 31, 2020 were evaluated. Demographic and clinical outcomes were assessed for patients. Physician responses to a survey were collected. RESULTS: Two hundred and thirty-one telemedicine visits were performed by 4 physicians, comprising 20% of visits during the study period. Patients were 47.6% male and 90.9% Caucasian. In addition, 85.7% were established patients and 21.2% were postoperative visits. Diagnoses evaluated by telemedicine included benign and malignant anorectal and colorectal disease as well as inflammatory bowel disease. All providers reported being able to provide adequate care via telemedicine and were planning to continue providing telemedicine. Patients seen via telemedicine were more likely to be Caucasian and less likely to be African American (P < .001) and more likely to be established patients than those seen in person (P < .001). CONCLUSION: During the COVID-19 pandemic, telemedicine was most successfully used to facilitate care for established patients, particularly the long-term care of colorectal cancer and inflammatory bowel disease. We identified significant differences in ethnicity between patients seen via telemedicine and those seen in person. Telemedicine represents an exciting advancement in patient care, although ongoing study is required regarding providing access to this technology to all colorectal surgery patients, particularly minority populations.

RESUMEN

The management of Crohn's disease has evolved significantly over the past 20 years. The arrival of biologic therapies has altered not only the management and outcomes but also rates for refractory disease requiring surgery. New surgical techniques have paralleled these medical advances, and this article will provide an overview of these new modalities as well as their outcomes. This is the first of a three-part series and will focus on terminal ileal and ileocolic disease.

RESUMEN

BACKGROUND: Healthcare reimbursement is rapidly moving away from a fee-for-service model toward value-based purchasing. An integral component of this new focus on quality is patient-centered outcomes. One metric used to define patient satisfaction is the Press Ganey Patient Satisfaction Survey. Data are lacking to accurately benchmark these scores based on diagnosis. We sought to identify if different colorectal disease processes affected a patient's perception of their healthcare experience. METHODS: Adult colorectal patients seen between July 2015 and September 2016 in a tertiary hospital colorectal clinic were mailed a Press Ganey survey. Patients were stratified based on diagnosis: neoplasia, IBD, anorectal and benign colorectal disease. Survey scores were compared across the groups with adjustment for confounding variables. RESULTS: 312 patients responded and formed the cohort. The mean age was 61 (range 18-93) and 56% were women. The cohort breakdown was 38% neoplasia, 32% anorectal, 21% benign, and 9% IBD. In a multivariable model, there was a difference in PG scores by diagnosis; patients with neoplasia had higher Overall scores (ß 10.2; Std Error 4.0; p = 0.01), Care Provider scores (ß 8.5; Std Error 4.2; p = 0.04), Nurse Assistant scores (ß 15.0; Std Error 5.7; p = 0.01), and Personal Issues scores (ß 11.8; Std Error 5/0; p = 0.01). CONCLUSION: Press Ganey scores were found to vary significantly. Patients with a neoplasia diagnosis reported higher overall satisfaction, Care Provider, Nurse Assistant, and Personal Issues scores. Adjustment for disease condition is important when assessing patient satisfaction as an indicator of quality and as a metric for reimbursement. This study adds to increasing evidence about bias in these scores.

RESUMEN

BACKGROUND: A subset of patients with rectal cancer who undergo neoadjuvant chemoradiation therapy will develop a complete pathologic tumor response. Complete nodal response is not universal in these patients and is difficult to assess clinically. Quantifying the risk of nodal disease would allow for targeted therapy with either radical resection or "watchful waiting." OBJECTIVE: This study aimed to identify risk factors for residual nodal disease in ypT0 rectal adenocarcinoma. DESIGN: This is a retrospective case control study. SETTINGS: The National Cancer Database 2006 to 2014 was used to identify patients for this study. PATIENTS: Patients with stage II/III rectal adenocarcinoma who completed chemoradiation therapy followed by resection and who had ypT0 tumors were included. Patients with metastatic disease and <2 lymph nodes evaluated were excluded. Patients were divided into 2 groups: node positive and node negative. MAIN OUTCOME MEASURES: The main outcome was nodal disease. The secondary outcome was overall survival. RESULTS: A total of 42,257 patients with stage II/III rectal cancer underwent chemoradiation therapy and radical resection; 4170 (9.9%) patients had ypT0 tumors and 395 (9.5%) were node positive. Of patients with clinically node-negative disease (ie, pretreatment imaging), 6.2% were node positive after chemoradiation therapy and resection. In multivariable analysis, factors predictive of nodal disease included increasing (pretreatment) clinical N-stage, high tumor grade (3/4), perineural invasion, and lymphovascular invasion. Higher clinical T-stage was inversely associated with residual nodal disease. Overall 5-year survival was significantly different between patients with ypN0, ypN1, and ypN2 disease (87.4%, 82.2%, and 62.5%, p = 0.002). LIMITATIONS: This study was limited by the lack of clinical detail in the database and the inability to assess recurrence. CONCLUSIONS: Ten percent of patients with ypT0 tumors had positive nodes after chemoradiation therapy and resection. Factors associated with residual nodal disease included clinical nodal disease at diagnosis and poor histologic features. Patients with any of these features should consider radical resection regardless of tumor response. Others could be suitable for "watchful waiting" strategies.

RESUMEN

OBJECTIVE: Inherited endocrinopathies are rare tumor predisposition syndromes associated with significant morbidity and mortality and have implications for both patients and their families. Prior studies suggest that early diagnosis of inherited endocrinopathies may reduce morbidity and mortality. Although genetic counseling and testing can help inform the appropriate management of at-risk relatives, barriers to care still exist. We explored patient perceptions to identify barriers and promote the uptake of genetic counseling. METHODS: An anonymous survey of patients from a multidisciplinary inherited endocrinopathy clinic at a tertiary care, university-based medical center was conducted. Data collected and analyzed included demographics, socioeconomic status, perceived risks, benefits, and both motivating and dissuading factors to genetic counseling and testing. RESULTS: Our study suggests barriers to genetic testing include concerns regarding cost and the potential for discrimination with respect to employers and insurers. CONCLUSION: This highlights the importance of genetic counseling to discuss benefits of genetic testing, while dispelling misperceptions. Knowledge of the common barriers to genetic counseling and testing can guide initiatives and education to foster genetic testing of at-risk relatives in the inherited endocrinopathy population.

RESUMEN

Significance: Although the wound healing cascade is similar in many tissues, in the gastrointestinal tract mucosal healing is critical for processes such as inflammatory bowel disease and ulcers and healing of the mucosa, submucosa, and serosal layers is needed for surgical anastomoses and for enterocutaneous fistula. Failure of wound healing can result in complications including infection, prolonged hospitalization, critical illness, organ failure, readmission, new or worsening enterocutaneous fistula, and even death. Recent Advances: Recent advances are relevant for the role of specific micronutrients, such as vitamin D, trace elements, and the interplay between molecules with pro- and antioxidant properties. Our understanding of the role of other small molecules, genes, proteins, and macronutrients is also rapidly changing. Recent work has elucidated relationships between oxidative stress, nutritional supplementation, and glucose metabolism. Thresholds have also been established to define adequate preoperative nutritional status. Critical Issues: Further work is needed to establish standards and definitions for measuring the extent of wound healing, particularly for inflammatory bowel disease and ulcers. In addition, a mounting body of evidence has determined the need for adequate preoperative nutritional supplementation for elective surgical procedures. Future Directions: A large portion of current work is restricted to model systems in rodents. Therefore, additional clinical and translational research is needed in this area to promote gastrointestinal wound healing in humans, particularly those suffering from critical illness, patients with enterocutaneous fistula, inflammatory bowel disease, and ulcers, and those undergoing surgical procedures.

RESUMEN

Increased growth of residual tumors in the proximity of acute surgical wounds has been reported; however, the mechanisms of wound-promoted tumor growth remain unknown. Here, we used a syngeneic, orthotopic mouse model of breast cancer to study mechanisms of wound-promoted tumor growth. Our results demonstrate that exposure of metastatic mouse breast cancer cells (4T1) to SDF-1α, which is increased in wound fluid, results in increased tumor growth. Both, wounding and exposure of 4T1 cells to SDF-1α not only increased tumor growth, but also tumor cell proliferation rate and stromal collagen deposition. Conversely, systemic inhibition of SDF-1α signaling with the small molecule AMD 3100 abolished the effect of wounding, and decreased cell proliferation, collagen deposition, and neoangiogenesis to the levels observed in control animals. Furthermore, using different mouse strains we could demonstrate that the effect of wounding on tumor growth and SDF-1α levels is host dependent and varies between mouse strains. Our results show that wound-promoted tumor growth is mediated by elevated SDF-1α levels and indicate that the effect of acute wounds on tumor growth depends on the predetermined wound response of the host background and its predetermined wound response.

RESUMEN

OBJECTIVE: Arginase plays important regulatory roles in polyamine, ornithine, and nitric oxide syntheses. However, its role in the healing process has not been delineated. In this study, we used a highly potent and specific inhibitor of arginase, namely 2(S)-amino-6-boronohexanoic acid NH4 (ABH) to evaluate the role of arginase function in wound healing. MATERIALS AND METHODS: ABH or saline was applied topically to full thickness, dorsal, excisional wounds in C57BL/6 mice every 8 hours for 14 days post surgery and the rate of wound closure was estimated planimetrically. Wound tissue was harvested from mice sacrificed on postoperative days 3 and 7 and examined histologically. The extent of epithelial, connective, and granulation tissue present within the wound area was estimated histomorphometrically. The effect of ABH on wound arginase activity, production of nitric oxide metabolites (NO(x)), and presence of smooth muscle actin positive cells (myofibroblasts) was evaluated. RESULTS: While arginase activity was inhibited in vivo, the rate of wound closure significantly increased 7 days post-surgery, (21 ± 4%: P < .01; Student t test) in ABH treated animals. This was accompanied by an early increase in wound granulation tissue and accumulation of NO(x) followed by enhanced re-epithelialization and localization of myofibroblasts beneath the wound epithelium. CONCLUSION: Arginase inhibition improves excisional wound healing and may be used to develop therapeutics for early wound closure.

RESUMEN

BACKGROUND: HMGB1, a non-histone chromosomal protein, can bind to the receptor for advanced glycation end products (RAGE) and act as an inflammatory mediator. We examined the role of HMGB1 in incisional wound healing and its possible mechanism of action through receptor for advanced glycation end products (RAGE). METHODS: Male Sprague-Dawley rats undergoing full-thickness incisional wounding with subcutaneous implantation of PVA sponges were given daily injections of ethyl pyruvate (EP) (40 mg/kg, i.p.), a potent inhibitor of HMGB1 release. At 7 d post-wounding, wound breaking strength, sponge collagen content, and wound fluid HMGB1 levels were assessed. In vitro rat dermal or wound-derived fibroblasts were cultured with recombinant HMGB1 or advanced glycation end product (AGE). Some cultures were co-treated with a RAGE-blocking antibody. Fibroblast proliferation and collagen synthesis were assayed. RESULTS: In vivo treatment with EP significantly decreased wound HMGB1 levels (P < 0.05), which was paralleled by increased wound breaking strength (P < 0.05) and wound collagen content (P < 0.05). In vitro treatment with HMGB1 (100 ng/mL) had no effect on fibroblast proliferation but significantly reduced collagen synthesis (P < 0.05). This effect was abrogated by co-treatment with anti-RAGE antibody. Fibroblasts treated with AGE had lower collagen synthesis (P < 0.01), which was restored by anti-RAGE antibody treatment. CONCLUSION: HMGB1 impairs fibroblast collagen synthesis. Reducing wound HMGB1 levels lead to increased tensile strength and collagen synthesis. The data suggest that HMGB1 affects collagen synthesis through activation of RAGE.

RESUMEN

Nutrition has always been noted to be one of the major influences on the successful outcome of wound healing. The exuberant cellular and biochemical events that constitute the wound-healing cascade require energy, amino acids, oxygen, metals, trace minerals, and vitamins for successful completion. Many nutritional deficiencies impact on wound healing by impeding fibroblast proliferation, collagen synthesis, and epithelialization. There are also nutrients that can enhance wound-healing responses. It is imperative for physicians to obtain a complete nutritional history and consider nutritional intervention as a means of affecting the course of healing. This review examines many of the advances that have occurred in understanding nutrition/wound interactions.

RESUMEN

The abdominal cavity represents one of the most active areas of surgical activity. Surgical procedures involving the gastrointestinal (GI) tract are among the most common procedures performed today. Healing of the GI tract after removal of a segment of bowel and healing of the peritoneal surfaces with subsequent adhesion formation remain vexing clinical problems. Interventions to modify both the responses are myriad, yet a full understanding of the pathophysiology of these responses remains elusive. Different aspects of GI and peritoneal healing, with associated factors, are discussed in this article.
