Surgical management of duodenal crohn's disease.

BACKGROUND: Operative options for duodenal Crohn's disease include bypass, stricturoplasty, or resection. What factors are associated with operation selection and whether differences exist in outcomes is unknown. METHODS: Patients with duodenal Crohn's disease requiring operative intervention across a multi-state health system were identified. Patient and operative characteristics, short-term surgical outcomes, and the need for future endoscopic or surgical management of duodenal Crohn's disease were analyzed. RESULTS: 40 patients underwent bypass (n = 26), stricturoplasty (n = 8), or resection (n = 6). Median age of diagnosis of Crohn's disease was 23.5 years, and over half of the patients had undergone prior surgery for CD. Operation type varied by the most proximal extent of duodenal involvement. Patients with proximal duodenal CD underwent bypass operations more commonly than those with mid- or distal duodenal disease (p = 0.03). Patients who underwent duodenal stricturoplasty more often required concomitant operations for other sites of small bowel or colonic CD (63%) compared to those who underwent bypass (39%) or resection (33%). No patients required subsequent surgery for duodenal CD at a median follow-up of 2.8 years, but two patients required endoscopic dilation (n = 1 after stricturoplasty, n = 1 after resection). CONCLUSION: Patients who require surgery for duodenal Crohn's disease appear to have an aggressive Crohn's disease phenotype, represented by a younger age of diagnosis and a high rate of prior resection for Crohn's disease. Choice of operation varied by proximal extent of duodenal Crohn's disease.

Creation and Implementation of an Online Tool for Feedback on Resident Teaching: A Pilot Study.

OBJECTIVE: There are few assessments of the competence and growth of surgical residents as educators. We developed and piloted an observation-based feedback tool (FT) to provide residents direct feedback during a specific teaching session, as perceived by medical students (MS). We hypothesized that residents' performance would improve with frequent, low stakes, observation-based feedback. SETTING: This prospective study took place at an academic general surgery program. PARTICIPANTS: Focus groups of MS, surgical residents, and faculty informed FT development. MS completed the FT regarding resident teaching. DESIGN: The FT utilized 5 slider-bar ratings (0 to 100) about the teaching encounter and a checklist of 16 desirable teaching behaviors. QR codes and weekly email links were distributed for 12 months (6 clerkship blocks) to promote use. Residents were sent their results after each block. A survey after each block assessed motivation for use and gathered feedback on the FT. Descriptive statistics were used for analysis (medians, IQRs). Primary measures of performance were median of the slider-bar scores and the number of teaching behaviors. RESULTS: The FT was used 111 times; 37 of 46 residents were rated by up to 65 MS. The median rating on the slider-bars was 100 and the median number of desirable teaching behaviors was 12; there were no differences based on gender or PGY level. 10 residents had 5 or more FT observations during the year. Four residents had evaluations completed in 4 or more blocks and 19 residents had evaluations completed in at least 2 blocks. Over time, 13 residents had consistent slider-bar scores, 1 resident had higher scores, and 5 residents had lower scores (defined as a more than 5-point change from initial rating). Frequency of use of the FT decreased over time (38, 32, 9, 21, 7, 5 uses per block). The post-use survey was completed by 24 MS and 19 residents. Most common reasons for usage were interest in improving surgical learning environment, giving positive feedback (MS), and improving teaching skills (residents). Most common reasons for lack of usage from residents were "I did not think I taught enough to ask for feedback," "I forgot it existed," and "I did not know it existed." CONCLUSIONS: The FT did not lead to any meaningful improvement in resident scores over the course of the year. This may be due to overall high scores, suggesting that the components of the FT may require reevaluation. Additionally, decreased utilization of the instrument over time made it challenging to assess change in performance of specific residents, likely due to lack of awareness of the FT despite frequent reminders. Successful implementation of observation-based teaching assessments may require better integration with residency or clerkship objectives.

Disparities in Clinical Trial Enrollment and Reporting in Rectal Cancer: A Systematic Review and Demographic Comparison to the National Cancer Database.

BACKGROUND: Cancer care guidelines based on clinical trial data in homogenous populations may not be applicable to all rectal cancer patients. The aim of this study was to evaluate whether patients enrolled in rectal cancer clinical trials (CTs) are representative of United States (U.S.) rectal cancer patients. METHODS: Prospective rectal cancer CTs from 2010 to 2019 in the United States were systematically reviewed. In trials with multiple arms reporting separate demographic variables, each arm was considered a separate CT group in the analysis. Demographic variables considered in the analysis were age, sex, race/ethnicity, facility location throughout the United States, rural vs urban geography, and facility type. Participant demographics from trial and the National Cancer Database (NCDB) participants were compared using chi-squared goodness of fit and one-sample t-test where applicable. RESULTS: Of 50 CT groups identified, 42 (82%) studies reported mean or median age. Trial participants were younger compared to NCDB patients (P < .001 all studies). All but three trials had fewer female patients than NCDB (48.2% female, P < .001). Less than half the CT groups reported on race or ethnicity. Eighteen out of 22 trials (82%) had a smaller percentage of Black patients and 4 out of 8 (50%) trials had fewer Hispanic or Spanish origin patients than the NCDB. No CTs reported comorbidities, socioeconomic factors, or education. CT primary sites were largely at academic centers and in urban areas. CONCLUSION: The present study supports the need for improved demographic representation and transparency in rectal cancer clinical trials.

Surgical Education: Disparities in Education May Impact the Quality and Likelihood of Completion of Training.

Female surgical trainees experience bias that begins at the preclinical stages of medical school, extending into their surgery clerkships, and then into their residency training. There are important implications in terms of training opportunities and career advancement, mentorship, sponsorship, and ultimately burnout. Childbearing and lactation also impact the experiences and perceptions of female trainees who have children. There are limited interventions that have improved the experience of women in surgical training. Mentorship appears to play an important role in ameliorating some of the negative consequences of the training environment and improving outcomes for women surgeons.

The impact of a "Residents as Teachers" Workshop at one year follow-up.

INTRODUCTION: "Residents as Teachers" (RaT) Workshops have been implemented in many General Surgery residency programs to improve resident teaching ability. The aim of this project was to assess whether there was significant degradation of teaching skills and knowledge one year after a RaT workshop. METHODS: A 4-h interactive workshop was delivered at an academic general surgery residency program. Pre- and post-workshop assessments evaluated participants' knowledge and confidence regarding teaching skills and they were re-evaluated one-year later. RESULTS: On a 5-point Likert scale, residents improved confidence and self-perception following the workshop was stable after one year. A decrease was found in the resident's perception of the education-related training received and scores on the knowledge-based questions. CONCLUSION: The confidence residents obtained from single-day RaT workshop was maintained at one year, but the knowledge was not. Resident perception of their educational training may benefit from more frequent reinforcement.

Functional Not Medical Frailty Is Associated With Long-Term Disability After Surgery for Colorectal Cancer.

BACKGROUND: Frailty has been associated with increased morbidity after surgery. However, few studies investigate long-term functional outcomes. METHODS:  Patients ≥ 65 years old who underwent surgery for colorectal cancer were surveyed regarding their ability to perform activities of daily living, measured by Barthel Index, before and after surgery. Patients also reported time to return to their functional baseline. RESULTS: Pre-operative moderate dependency was associated with declining function at six months (OR: 8.8; CI: 1.8-42.6) and one year post-operatively (OR: 17.5; CI: 2.8-109.8). Pre-operative functional frailty was associated with subjective failure to return to baseline (OR: 4.8 and 4.2) for slightly and moderately dependent patients and a longer time to return to baseline. Medical frailty, based on the modified Frailty Index, was not significantly associated with failure to return to baseline. CONCLUSIONS: Measures of functional frailty are better predictors of failure to return to baseline, than measures of medical frailty.

General Surgery Residents' Retention of Knowledge After an Anorectal Skills Workshop.

INTRODUCTION: Studies have demonstrated suboptimal resident exposure to anorectal pathology. A workshop was developed at an academic general surgery residency. This study assesses durability of learning from the workshop. METHODS: Thirty-six residents participated in a skills laboratory addressing diagnosis and management of anorectal complaints. The skills laboratory was broken into didactic and hand-on skills stations. Residents completed pre-, post- and 6-mo after workshop assessments to evaluate knowledge and confidence. Knowledge and confidence-based scores pre-, post- and 6-mo after workshop were compared. RESULTS: Scores demonstrated retention of information. Knowledge-based question median scores improved from 63.2% pre-workshop to 73.7% post-workshop and 76.3% at 6 mo (P = 0.0005). Median confidence scores improved from 31 pre-workshop to 40 post-workshop, and were stable at 6 mo (P = 0.0001). CONCLUSIONS: Knowledge and confidence gained from an anorectal skills workshop was stable or improved at 6 mo. These results suggest that an anorectal curriculum is effective at improving general surgery resident background knowledge and confidence when managing anorectal complaints.

Effects of surgical approach on short- and long-term outcomes in early-stage rectal cancer: a multicenter, propensity score-weighted cohort study.

BACKGROUND: Randomized controlled trials have been unable to demonstrate noninferiority of minimally invasive surgery for rectal cancer. The aim of this study was to assess oncologic resection success, short- and long-term morbidity, and overall survival by operative approach in a homogenous early-stage rectal cancer cohort. METHODS: This is a multicenter, propensity score-weighted cohort study utilizing deidentified data from the National Cancer Database. Individuals who underwent a formal proctectomy for early-stage rectal cancer (T1-2, N0, M0) from 2010 to 2015 were included. The primary outcome was a composite variable indicating successful oncologic resection stratified by operative approach, defined as negative margins with at least 12 lymph nodes evaluated. RESULTS: Among 3649 proctectomies for rectal adenocarcinoma, 1660 (45%) were approached open, 1461 (40%) laparoscopically, and 528 (15%) robotically. After propensity score weighting, compared to open approach, there were no differences in odds of successful oncologic resection (ORadj = 1.07, 95% CI 0.9, 1.28 and ORadj = 1.28, 95% CI 0.97, 1.7). Open approach was associated with longer mean (± SD) length of stay compared to laparoscopic (7.7 ± 0.18 vs. 6.5 ± 0.25 days, p < 0.001) and robotic (7.7 ± 0.18 vs. 6.3 ± 0.35 days, p < 0.001) approaches. In regard to 90-day mortality, compared to open approach, laparoscopic (ORadj = 0.56, 95% CI 0.36, 0.88) and robotic (ORadj = 0.45, 95% CI 0.22, 0.94) approaches were associated with a reduced odd of 90-day mortality. This mortality benefit persists in the long-term for laparoscopic approach (p = 0.003). CONCLUSION: For individuals with early-stage rectal cancer treated with proctectomy, successful oncologic resection can be achieved irrespective of technical approach. Minimally invasive approaches provide short-term reduction in morbidity. Surgical approach must be tailored to each patient based on surgeon experience and judgement in collaboration with a multi-disciplinary team.

Neoadjuvant radiation above NCCN guidelines for rectal cancer is associated with age under 50 and early clinical stage.

INTRODUCTION: Recent data suggest patients with early-onset rectal cancer (EORC) receive neoadjuvant radiation above recommended doses without oncologic benefit. The use of excessive radiation may lead to worse outcomes and patient harm. We sought to evaluate predictors of aggressive neoadjuvant radiation (A-XRT) use in EORC patients and compare this to late-onset rectal cancer (LORC) patients. METHODS: The National Cancer Database from 2004 to 2014 was queried for rectal adenocarcinoma patients undergoing surgical resection. Patients with stage 0 or IV disease, positive margins, and incomplete data were excluded. Standard neoadjuvant radiation (S-XRT) was based upon NCCN guidelines: 25-50.4 Gray for stage II/III patients and none for stage I. Excess radiation was considered A-XRT. Patients diagnosed at age < 50 years were labeled EORC; those ≥ 50 years were LORC. Categorical data were analyzed with chi-square test. Logistic regression was used to analyze clinicodemographic associations with A-XRT. RESULTS: 45,403 patients were included: 7999 (17.6%) EORC and 37,404 (82.4%) LORC. Multivariable logistic regression demonstrated that A-XRT use among stage I patient was associated with male gender, age under 50, urban location, mucinous histology, and poor tumor differentiation. Among stage II and III patients, A-XRT use was associated with male gender, age under 50, higher education and income, and urban location. Cox hazards did not demonstrate a significant association of A-XRT use with survival. CONCLUSION: Our data reaffirm that EORC patients more frequently receive A-XRT and that use is based on demographic features independent of tumor characteristics. Reasons for A-XRT, particularly in EORC patients, should be clarified to promote adherence to guidelines and minimize patient harm.

Predictors of curative-intent oncologic management among patients with stage IV rectal cancer.

BACKGROUND: Management of stage IV rectal adenocarcinoma is categorized into curative and palliative-intent strategies. The aim of this study is to determine the incidence of and associations with curative-intent treatment in stage IV rectal cancer. METHODS: The National Cancer Database from 2010 to 2016 was queried for patients with stage IV rectal adenocarcinoma and were grouped into curative-intent and non-curative management. Multivariable logistic regression was used to predict use of curative-intent management. RESULTS: 16,862 patients were included in this study: 4886 (30.0%) curative-intent and 11,975 (71.0%) non-curative. Multivariable regression demonstrated curative intent was associated with young age, female gender, white race, private insurance, mucinous histology and anaplastic grade. CONCLUSION: Use of curative intent oncologic management among patients with stage IV rectal adenocarcinoma is influenced by age, tumor biology and location of metastatic disease. Association with gender and insurance imply the presence of disparity in the delivery of cancer care among this patient population.

Evaluation of Demographics and Management of Rectal Cancer by Age Group: A Retrospective Propensity Matched Cohort Analysis of the National Cancer Database.

Background Data suggests there are demographic and biological differences in colon cancer between young and typical-onset patients. However, it is unclear if these differences persist in rectal cancer patients, exclusive of colon cancer. This is a retrospective review of a large national database to evaluate age-based differences in demographics, tumor features, and treatment among patients with rectal adenocarcinoma. Methods The National Cancer Database from 2004-2014 was queried for rectal adenocarcinoma. Patients were grouped by age at diagnosis: early-onset, defined as <40 years, mid-onset 40-49, and late-onset ≥50. Propensity matching controlled for demographic variation among cohorts. Pairwise Chi-square with Bonferroni correction was used for analysis. Results Thirty thousand nine hundred seventy-eight patients were included: 1,249 (4%) early-onset, 4,156 (13%) middle-onset, and 25,573 (83%) late-onset. Significant differences existed between all three cohorts in nearly all demographic and pathologic metrics. Control for demographic variation revealed early-onset and middle-onset cohorts differed only with respect to the stage at presentation, while early-onset and late-onset cohorts differed more significantly on the basis of stage, histology, and oncologic management. Conclusion The demographic differences observed demonstrate that patients under 50 should not be considered one cohort. Propensity matching led to a decrease in tumor trait differences among cohorts, suggesting that demographics other than age drive variation in tumor biology. Young patients received more aggressive management, implying the presence of an age bias. Age-based screening is likely insufficient and may exclude the rising proportion of young patients at risk for disease, while age-based management may lead to under- or overtreatment of patients at either end of the age spectrum.

Evaluating disparities in delivery of neoadjuvant guideline-based chemoradiation for rectal cancer: A multicenter, propensity score-weighted cohort study.

BACKGROUND: Despite guideline recommendations, some patients still receive care inappropriate for their clinical stage of disease. Identification of factors that contribute to variation in guideline base care may help eradicate disparities in the treatment of early and locally advanced rectal cancer. METHODS: The American College of Surgeons National Cancer Database from 2010 to 2015 was analyzed with propensity score weighting to identify factors associated with delivery and omission of neoadjuvant guideline-based chemoradiation (GBC) for those with early and locally advanced rectal cancer. RESULTS: Only 74% of patients with rectal cancer received stage-appropriate neoadjuvant chemoradiation; 4544 (88%) of those with early stage disease and 8675 (68%) in locally advanced disease. Chemotherapy and radiotherapy were not planned in 27% and 34% respectively, of those who did not receive GBC. Factors associated with receipt of non-guideline-based neoadjuvant chemoradiation were age >65 years, Medicare insurance, treatment at a community facility, West-South-Central geography, having locally advanced disease, and Charlson-Deyo score >3. Receipt of ideal guideline-based neoadjuvant chemoradiation conferred a survival benefit at 5 years. CONCLUSION: Patient and non-patient factors contribute to disparities in guideline-based delivery of neoadjuvant chemoradiation in the treatment of rectal cancer. Identification of these risk factors are important to help standardize care and improve survival outcomes.

Effect of "Residents as Teachers" Workshop on Learner Perception of Trainee Teaching Skill.

BACKGROUND: Surgical residencies use variable structures for formal training in education. We hypothesized that a one-day workshop intervention would improve resident teaching ability measured by self-assessment and learner evaluation. MATERIALS AND METHODS: Faculty educators delivered a Residents as Teachers (RAT) workshop to general surgery residents on setting expectations, positive learning environment, difficult feedback and the 1-min preceptor model. For three months before and after the workshop, junior residents and medical students evaluated their supervising residents' teaching skill monthly using a Likert scale questionnaire. Pre- and postworkshop surveys were administered to resident participants to assess their knowledge of the material and teaching confidence. Results were analyzed using Wilcoxon rank sum tests. This study was conducted at a tertiary academic center with a large surgical residency program. RESULTS: Thirty-nine PGY 1-5 residents participated in the Residents as Teachers workshop and were included in the study. Pre- and post- workshop survey results demonstrated significant improvements in participants' knowledge and teaching confidence. On monthly assessments of seniors by junior residents, significant improvements were noted in three domains. Medical student ratings did not reflect significant improvements in resident teaching skill. CONCLUSIONS: This is the first study using learner evaluation of a comprehensive surgical RAT program. Despite a significant increase in surgery residents' self-assessment following participation in an education workshop, no improvement was seen in resident teaching skill as perceived by medical students.

Population demographics in geographic proximity to hospitals with robotic platforms do not correlate with disparities in access to robotic surgery.

BACKGROUND: Disparities in access to robotic surgery have been shown on the local, regional, and national level. This study aims to see if the location of hospitals with robotic platforms (HWR) correlates with population trends to explain the disparity in access to robotic surgery. METHODS: Hospitals with da Vinci surgical systems were identified by compiling data from the publicly available da Vinci surgeon locator website. Demographic, and economic data were compiled. Multivariate logistic regression and place-based analysis were used to determine population characteristics associated with geographic proximity to HWR. RESULTS: The United States has 1971 HWR (5.93 hospitals with robots per 1 million people). The states with the most HWR are Texas (203), California (175), and Florida (162). Multivariate logistic regression analysis of Texas counties determined population (OR 1.97, 95% CI 1.40-3.38) education level (OR 1.64, 95% CI 1.07-3.21), and urban designation (OR 1.15, 95% CI 1.05-1.31) remained significantly associated with HWR. When applied to a national level, population remained associated with higher numbers of HWR (R = 0.945), however level of education and urbanization were not. CONCLUSIONS: Based on this study of population-level data, disparities in access to robotic surgery seen in prior literature cannot be explained exclusively by sociodemographic factors related to the geographic proximity of HWR. This suggests other biases are involved in the lack of robotic procedures performed among minority and underprivileged populations.

Gender Equity at Surgical Conferences: Quantity and Quality.

BACKGROUND: Participation of women at national surgery conferences is an important aspect of achieving gender equity; however, participation has to be meaningful and representative of scientific and clinical achievement. We hypothesized that the presence of women on planning committees would increase the number of women speakers and the presence of women as moderators would increase the number of women panelists. Furthermore, we hypothesized that although women may be included as speakers, they are less likely to speak on clinical and technical surgical topics than men. METHODS: Four 2018 national surgery conferences were chosen for investigation: Eastern Association for the Surgery of Trauma, Society of American Gastrointestinal and Endoscopic Surgeons, Academic Surgical Conference, and the American Society of Breast Surgeons because of varied subject matter. The published online conference programs were reviewed and participant gender, presentation role, type, and topic were recorded. Submitted abstract and scientific articles were excluded from analysis; moderators of these sessions were included. Statistical analyses were performed using chi-squared tests and t-tests where appropriate. RESULTS: The overall mean percentage of female speakers was 28%. The percentage of women on the program committees positively correlated with the number of women speaking at the conference (Eastern Association for the Surgery of Trauma, 15.4% women on committee vs 18.92% speakers; Society of American Gastrointestinal and Endoscopic Surgeons, 27% versus 22%; Academic Surgical Conference, 38.5% versus 32%; and the American Society of Breast Surgeons, 50% versus 58.55 %; P < 0.001). Panels with greater than 50% female moderators were more likely to have female panelists than those with less than 50% female moderators (23.6% versus 14.8%; P < 0.001). Women were most likely to present awards, introductions, and keynote speeches, then most likely to speak on professionalism (54.84% and 36.29%; P < 0.001). They were significantly less likely to present on a clinical topic, technical skill, or moderate a scientific presentation (25.68% and 26.75%; P < 0.001). CONCLUSION: Despite increasing attention on improving diversity at surgical conferences, disparities continue to persist. As demonstrated in nonsurgical literature, planning committee gender diversity positively correlated with speaker diversity, and moderator diversity positively correlated with panel diversity. Women were more likely to speak on topics considered "soft sciences", such as professionalism and advocacy, and less likely to present on clinical topics, technical skill, or scientific research.

Intimate Partner Violence Among Surgeons: We are Not Immune.

OBJECTIVE: The incidence and risk factors for IPV are not well-studied among surgeons. We sought to fill this gap in knowledge by surveying surgeons to estimate the incidence and identify risk factors associated with IPV. SUMMARY OF BACKGROUND DATA: An estimated 36.4% of women and 33.6% of men in the United States have experienced IPV. Risk factors include low SES, non-White ethnicity, psychiatric disorders, alcohol and drug abuse, and history of childhood abuse. Families with higher SES are not exempt from IPV, yet there is very little data examining incidence and risk factors among these populations. METHODS: An anonymous online survey targeting US-based surgeons was distributed through 4 major surgical societies. Demographics, history of abuse, and related factors were assessed. Chi-square analysis and multivariable logistic regression were utilized to evaluate for potential risk factors of IPV. RESULTS: Eight hundred eighty-two practicing surgeons and trainees completed the survey, of whom 536 (61%) reported experiencing some form of behavior consistent with IPV. The majority of respondents were women (74.1%, P = 0.004). Emotional abuse was most common (57.3%), followed by controlling behavior (35.6%), physical abuse (13.1%), and sexual abuse (9.6%).History of mental illness, [odds ratio (OR) 2.32, P < 0.001], alcohol use (frequent/daily OR 1.76, P = 0.035 and occasional OR 1.78, P = 0.015), childhood physical abuse (OR 1.96, P = 0.020), childhood emotional abuse (OR 1.76, P = 0.008), and female sex (OR 1.46, P = 0.022) were associated with IPV. CONCLUSIONS: As the first national study of IPV among surgeons, this analysis demonstrates surgeons experience IPV and share similar risk factors to the general population.

Prophylactic Gynecologic Surgery at Time of Colectomy Benefits Women with Lynch Syndrome and Colon Cancer: A Markov Cost-Effectiveness Analysis.

BACKGROUND: Women with Lynch syndrome who have completed childbearing should be offered prophylactic hysterectomy and bilateral salpingo-oophorectomy for gynecologic cancer prevention. The benefit of prophylactic gynecologic surgery at the time of colon cancer resection is unclear. OBJECTIVE: This study aimed to compare the cost, quality of life, and likelihood of being alive and free from colon, endometrial, and ovarian cancer between operative choices for patients with Lynch syndrome undergoing surgery for colon cancer. DESIGN: A Markov decision tree spanning 40 years was constructed for a hypothetical cohort of 30-year-old women with Lynch syndrome who had been diagnosed with colon cancer. Outcomes of 6 surgical strategies were compared, including segmental or total abdominal colectomy with or without hysterectomy alone or combined with bilateral salpingo-oophorectomy. SETTINGS: A Markov cost-effectiveness analysis was performed at a single center. PATIENTS: A literature search was performed identifying studies of patients with genetically diagnosed Lynch syndrome that described cost, risk of mortality, and quality of life after colon cancer resection and prophylactic gynecologic surgery. MAIN OUTCOME MEASURES: The primary outcomes measured were quality-adjusted life-years and the likelihood of being alive and free from colon, endometrial, and ovarian cancer 40 years after surgery. RESULTS: Women with Lynch syndrome who underwent a total abdominal colectomy and hysterectomy with bilateral salpingo-oophorectomy had the highest likelihood of being alive and cancer free. Total abdominal colectomy with hysterectomy was a close second, but yielded the largest amount of quality-adjusted life-years and lowest cost. LIMITATIONS: This study is limited by the statistical method and quality of studies used. CONCLUSIONS: Total abdominal colectomy with prophylactic hysterectomy at 30 years of age was the most cost-effective surgical choice in women with Lynch syndrome and colon cancer. The addition of bilateral salpingo-oophorectomy offered the highest event-free survival and lowest mortality. However, the additional morbidity of premature menopause of prophylactic salpingo-oophorectomy for younger women outweighed the benefit of ovarian cancer prevention.

LA CIRUGÍA GINECOLÓGICA PROFILÁCTICA EN EL MOMENTO DE LA COLECTOMÍA BENEFICIA A LAS MUJERES CON SÍNDROME DE LYNCH Y CÁNCER DE COLON: UN ANÁLISIS DE COSTO-EFECTIVIDAD DE MARKOV: Las mujeres con síndrome de Lynch que han completado la maternidad deberían recibir histerectomía profiláctica y salpingooforectomía bilateral para la prevención del cáncer ginecológico. El beneficio de la cirugía ginecológica profiláctica en el momento de la resección del cáncer de colon no está claro.Comparar el costo, la calidad de vida y la probabilidad de estar viva y libre de cáncer de colon, endometrio y ovario entre las opciones quirúrgicas para pacientes con síndrome de Lynch sometidos a cirugía por cáncer de colon.Se construyó un árbol de decisión de Markov que abarca cuarenta años para una cohorte hipotética de mujeres de 30 años con síndrome de Lynch diagnosticadas con cáncer de colon. Se compararon los resultados de seis estrategias quirúrgicas, incluida la colectomía abdominal segmentaria o total con o sin histerectomía sola o combinada con salpingooforectomía bilateral.Se realizó un análisis de costo-efectividad de Markov en un solo centro.se realizó una búsqueda bibliográfica para identificar estudios de pacientes con síndrome de Lynch con diagnóstico genético que describieron el costo, el riesgo de mortalidad y la calidad de vida después de la resección del cáncer de colon y la cirugía ginecológica profiláctica.años de vida ajustados por calidad y probabilidad de estar vivo y libre de cáncer de colon, endometrio y ovario 40 años después de la cirugía.Las mujeres con síndrome de Lynch que se sometieron a una colectomía e histerectomía abdominal total con salpingooforectomía bilateral tuvieron la mayor probabilidad de estar vivas y libres de cáncer. La colectomía abdominal total con histerectomía fue un segundo lugar cercano, pero produjo la mayor cantidad de años de vida ajustados por calidad y el costo más bajo.Este estudio está limitado por el método estadístico y la calidad de los estudios utilizados.La colectomía abdominal total con histerectomía profiláctica a los 30 años fue la opción quirúrgica más rentable en mujeres con síndrome de Lynch y cáncer de colon. La adición de salpingooforectomía bilateral ofreció la mayor supervivencia libre de eventos y la menor mortalidad. Sin embargo, la morbilidad adicional de la menopausia prematura de la salpingooforectomía profiláctica para las mujeres más jóvenes superó el beneficio de la prevención del cáncer de ovario.

Where is the leak in the surgeon pipeline?

INTRODUCTION: In order to care for an increasingly diverse population, the surgical workforce must improve in gender, racial, and ethnic diversity. We aim to identify deficiencies in the surgical pipeline. METHODS: Data from the United States Census, Bureau of Labor Statistics, and Association of American Medical Colleges were collected from 2004 to 2018, and evaluated for changing population over time. RESULTS: Women comprise 51% of the population, 32% of surgeons, and representation is increasing at a rate of 0.4% per year. 13% of the population and 6% of surgeons are black, and representation is decreasing at a rate of -0.1% per year. Hispanics represent 18% of the population, 6% of surgeons, and representation is increasing at a rate of 0.04% per year. CONCLUSIONS: While the proportion of women and Hispanic surgeons is slowly increasing, the proportion of black surgeons is decreasing. Recruitment methods need to be focused to improve surgical workforce diversity.
