RESUMEN
AIM: The National Accreditation Program for Rectal Cancer (NAPRC) was developed to improve rectal cancer patient outcomes in the United States. The NAPRC consists of a set of process and outcome measures that hospitals must meet in order to be accredited. We aimed to assess the potential of the NAPRC by determining whether achievement of the process measures correlates with improved survival. METHODS: The National Cancer Database was used to identify patients undergoing curative proctectomy for non-metastatic rectal cancer from 2010 to 2014. NAPRC process measures identified in the National Cancer Database included clinical staging completion, treatment starting <60 days from diagnosis, carcinoembryonic antigen level measured prior to treatment, tumour regression grading and margin assessment. RESULTS: There were 48 669 patients identified with a mean age of 62 ± 12.9 years and 61.3% of patients were men. The process measure completed most often was assessment of proximal and distal margins (98.4%) and the measure completed least often was the serum carcinoembryonic antigen level prior to treatment (63.8%). All six process measures were completed in 23.6% of patients. After controlling for age, gender, comorbidities, annual facility resection volume, race and pathological stage, completion of all process measures was associated with a statistically significant mortality decrease (Cox hazard ratio 0.88, 95% CI 0.81-0.94, P < 0.001). CONCLUSION: Participating institutions provided complete datasets for all six process measures in less than a quarter of patients. Compliance with all process measures was associated with a significant mortality reduction. Improved adoption of NAPRC process measures could therefore result in improved survival rates for rectal cancer in the United States.

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.

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.

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.

BACKGROUND: Although guidelines recommend open adrenalectomy for most resectable adrenal malignancies, minimally invasive adrenalectomies are performed. Robotic adrenalectomies have become more popular recently, but there is a paucity of literature comparing laparoscopic and robotic resections. METHODS: Patients who underwent a planned minimally invasive adrenalectomy for adrenal malignancies (adrenocortical carcinoma, malignant pheochromocytoma, other carcinoma) were identified in the National Cancer Database. The primary outcome was the conversion rate from minimally invasive to open. Other post-operative outcomes and survival were compared. RESULTS: 416 patients (76.5%) underwent a laparoscopic adrenalectomy and 128 (23.5%) underwent a robotic operation. Demographics and clinical characteristics were similar. Approximately 19% of tumors resected by a minimally invasive approach were > 10 cm. The intra-operative conversion rate was decreased among robotic adrenalectomies relative to laparoscopic on univariate (7.8% vs. 18.3%, p = 0.005) and multivariable (odds ratio 0.39, p = 0.01) analyses. Using marginal standardization, there was a stepwise increase in the conversion rate as tumor size increased (< 5, 5-10, > 10 cm) for laparoscopic (7.5%, 18.0%, 33.2%) and robotic (3.1%, 8.3%, 17.3%) adrenalectomies. Operations which required conversion had a greater margin positivity rate, greater length of stay, and an association with poor overall survival. CONCLUSION: In contrast to most clinical guidelines, minimally invasive adrenalectomies are being performed on large malignant tumors. A laparoscopic approach was associated with a greater conversion rate and subsequent poor outcomes. If a surgeon is not planning an open adrenalectomy, but adrenal malignancy is a possibility, robotic adrenalectomy may be the preferred approach for resectable adrenal tumors.

BACKGROUND: Guidelines recommend resection of non-functional neuroendocrine tumors of the pancreas (NF-pNETs) that are ≥2 cm in size. We compared utilization of surgery based on race. METHODS: We identified non-Hispanic White and Black patients with localized NF-pNETs ≥2 cm and Charlson-Deyo score 0-1 in the NCDB (2004-2016). We compared utilization of surgery by race, adjusting for clinicodemographic variables. Overall survival was compared based on management. RESULTS: A total of 3459 patients were included (White = 3005; Black = 454). Black patients were younger (58vs63 years) and more often treated at academic facilities (65.3%vs60.3%). Overall, Black and White patients underwent surgery at similar rates (77.3%vs79.6%). When stratified by primary site, Black patients with body/tail tumors were less likely to undergo surgery (78.5%vs84.7%). On multivariable analysis, Black race was associated with a lower likelihood of surgery overall (OR 0.74,p = 0.034) and in patients with body/tail tumors (OR 0.56,p = 0.001). Non-operative management was associated with a higher risk of death (HR 3.19,p < 0.001). CONCLUSION: In a national cohort of patients with NF-pNETs meeting criteria for resection, Black race is associated with lower frequency of surgery. Operative intervention is associated with prolonged survival. Persistent racial disparities in management of a surgically curable disease should be targeted for improvement.

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.

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.

BACKGROUND: Adrenocortical carcinoma (ACC) is often a contraindication to minimally invasive adrenalectomy (MIA). We used an administrative data set to analyze postoperative outcomes. We hypothesized that small tumors would have better short- and long-term outcomes, independent of the operative approach. METHODS: The National Cancer Database (2010-2016) identified patients with ACC who underwent adrenalectomy. Tumors were grouped: <5 cm (n = 125), 5-10 cm (n = 431), and >10 cm (n = 443). The primary and secondary outcomes were margin positivity and overall survival, respectively. RESULTS: Nine hundred and ninety-nine patients were analyzed: 37% MIA and 63% open adrenalectomy (OA). As the size increased, the rate of attempted MIA decreased. Larger tumors were associated with conversion to open. Although tumors with local invasion and those which required conversion to open were associated with an increased likelihood of a positive margin, tumor size was not. Although "complete" MIA (vs. OA) and tumor size were not associated with differences in survival, conversion (HR = 1.83, p = .02), positive margins (HR = 1.54, p = .01), and local invasion (HR = 1.84, p < .001) were associated with poor survival. CONCLUSION: Positive margins are associated with poor survival in ACC. Tumors ≥ 5 cm were associated with an increased conversion rate and subsequent increase in margin positivity. MIA may be considered for select patients with small tumors but adequate oncologic resection is critical.

BACKGROUND AND OBJECTIVES: This study investigated the impact of treating facility type on guideline-concordant sentinel lymph node biopsy (SLNB) management in T1a* (defined as a Breslow depth <0.76 mm without ulceration or mitoses) and T2/T3 melanoma. METHODS: This was a retrospective cohort study utilizing the National Cancer Database from 2012 to 2016. RESULTS: Our cohort included 109,432 patients. For T1a* melanomas, 85% of patients received guideline-concordant SLNB management at community and academic facilities versus 75% of patients at integrated network facilities (p < .001). Over 83% of patients with T2/T3 melanoma treated at an academic facility received guideline-concordant SLNB management versus 77% treated at a community facility (p < .001). Adjusting for demographic and clinical factors, integrated (adjusted odds ratio, aOR = 0.54), and comprehensive community (aOR = 0.74) facilities were less likely to provide guideline-concordant SLNB management in patients with T1a* melanoma compared to academic facilities. Community facilities (aOR = 0.72) were less likely to provide guideline-concordant SLNB management in patients with T2/T3 melanoma compared to academic facilities. CONCLUSION: Academic facilities provide the highest rate of guideline-concordant sentinel lymph node management. Comparatively, community programs may underutilize SLNB in T2/T3 disease, while integrated and comprehensive community facilities may over-utilize SLNB in T1a* disease.

BACKGROUND: Per oral endoscopic myotomy (POEM) is used to treat a variety of esophageal motility disorders and is associated with relatively few complications. However, complications in patients on antithrombotic therapy (AT) is not well-studied. We hypothesize AT patients have a higher risk of post-operative bleeding and 30-day complication rate compared to all other patients, even when these medications are held peri-operatively. METHODS: A single-institution retrospective review of a prospectively collected database of patients who underwent POEM procedures January 2011-July 2019 was performed. All 30-day complications were recorded, as well as management of AT medications peri-operatively. Demographic and clinical characteristics were compared using t test, Chi-Square, and Fisher's exact test as appropriate. Multivariate logistic regression was performed to examine factors associated with post-operative complications. RESULTS: A total of 219 POEM procedures were performed. 50.2% of patients were male, and AT patients tended to be older (66.9 vs. 55.4, p = 0.01). The major complication rate was higher among AT patients (36.8% vs. 9.0%, p = 0.01), as was the rate of post-operative bleeding (10.5% vs. 1.0%, p = 0.04). After adjusting for gender and age, the use of antithrombotic therapy was significantly associated with 30-day complications (OR 6.03, p = 0.001). CONCLUSIONS: Patients on AT who undergo POEM are significantly more likely to experience complications, including bleeding, within 30 days of surgery. Safe timing of post-operative resumption of antithrombotic medications remains a difficult decision that must be carefully considered by the endoscopist.

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.

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.

BACKGROUND AND OBJECTIVES: Sarcopenia is associated with poor long-term outcomes in many gastrointestinal cancers, but its role in anal squamous cell carcinoma (ASCC) is not defined. We hypothesized that patients with sarcopenic ASCC experience worse long-term outcomes. METHODS: A retrospective review of patients with ASCC treated at an academic medical center from 2006 to 2017 was performed. Of 104 patients with ASCC, 64 underwent PET/computed tomography before chemoradiation and were included in the analysis. The skeletal muscle index was calculated as total L3 skeletal muscle divided by height squared. Sarcopenia thresholds were 52.4 cm2 /m2 for men and 38.5 cm2 /m2 for women. Cox regression analysis was performed to assess overall and progression-free survival. RESULTS: Twenty-five percent of the patients were sarcopenic (n = 16). Demographics were similar between groups. There was no difference in the clinical stage or comorbidities between groups. On multivariate analysis, factors associated with worse overall survival were male gender (hazard ratio [HR] 3.7, P = .022) and sarcopenia (HR 3.6, P = .019). Male gender was associated with worse progression-free survival (HR 2.6, P = .016). CONCLUSIONS: Sarcopenia is associated with worse overall survival in patients with anal cancer. Further studies are indicated to determine if survival can be improved with increased attention to nutritional status in sarcopenic patients.

BACKGROUND AND OBJECTIVES: Right-sided colon cancers (R-CC) are associated with worse outcomes compared to left-sided colon cancers (L-CC). We hypothesize that R-CC with synchronous liver metastases who undergo resection of primary and metastatic sites have worse survival and that survival will vary significantly among R-CC, L-CC, and rectal cancer (ReC). METHODS: The Surveillance, Epidemiology, and End Results (SEER) database from 2010 to 2016 was used to identify colorectal cancer patients with liver metastases who underwent surgical resection of both primary and metastatic disease. Survival was analyzed by multivariate Cox regression. RESULTS: A total of 2275 patients were included; 38% R-CC, 46% L-CC, and 16% ReC. R-CC primary tumors tended to be larger than 5 cm, higher grade, and mucinous (all P < .001). Compared to patients with R-CC, both L-CC and ReC had improved overall (HR 0.72; P < .001; HR 0.75, P = .006) and disease-specific (HR 0.71, P < .001; HR 0.73, P = .008) survival. There was no difference in survival between L-CC and ReC. CONCLUSIONS: Patients with R-CC have significantly worse survival than L-CC or ReC. This provides additional evidence that R-CC tumors are fundamentally different from L-CC and ReC tumors. Future studies should determine factors responsible for this disparity, and identify targeted treatment based on primary tumor location.
RESUMEN
BACKGROUND: Socioeconomic and racial differences have been associated with disparities in cancer care within the US, including disparate access to minimally invasive surgery for rectal cancer. We hypothesized that robotic approach to rectal cancer may be associated with similar disparities. METHODS: The National Cancer Database (NCDB) was used to identify patients over 18 years old with clinical stage I-III rectal adenocarcinoma who underwent a proctectomy between 2010 and 2014. Demographic and hospital factors were analyzed for association with robotic approach. Factors identified on bivariate analyses informed multivariate analysis. RESULTS: We identified 33,503 patients who met inclusion criteria; 3702 (11.1%) underwent robotic surgery with 7.8% conversion rate. Patients who received robotic surgery were more likely to be male, white, privately insured and with stage III cancer. They were also more likely to live in a metropolitan area, more than 25 miles away from the hospital and with a higher high school graduation rate. The treating hospital was more likely to be academic and high volume. CONCLUSIONS: Robotic surgery is performed rarely and access to it is limited for patients who are female, black, older, non-privately insured and unable to travel to high-volume teaching institutions. The advantages of robotic surgery may not be available to all patients given disparate access to the robot. This inherent bias in access to robot may skew study populations, preventing generalizability of robotic surgery research.

BACKGROUND: Minimally invasive surgery is now preferred to open in many surgical procedures. This has led to changes in training to ensure skills acquisition and education in minimally invasive technique. There have been limited data regarding the effect of the number of open procedures being performed in training. The aim of this paper is to examine the relationship in trends for open and laparoscopic procedures performed by general surgery residents. METHODS: A retrospective review of the Accreditation Council for Graduate Medical Education publicly available resident case log statistical reports for the academic years from 1999-2000 to 2017-2018 was performed for laparoscopic and open anti-reflux surgery, appendectomy, colectomy, splenectomy, and inguinal hernia repair. The data were grouped by time period and compared to evaluate changes in operative patterns. RESULTS: The mean number for all (open and MIS) of the selected procedures increased from 159.1 in 2000 to 223.8 in 2018 (40.7%). The mean number of laparoscopic cases increased from 23.6 to 135.6 (462%), and open decreased from 135.5 to 88.2 (- 34.9%). There was a significant decrease in the average number of open procedures performed in each period among anti-reflux operations (3.4, 1.8, 1.5, 0.7, p < 0.01), appendectomy (30.7, 23.4, 13.6, 6.8, p < 0.01), and splenectomy (3.0, 2.0, 1.6, 1.4, p < 0.05); the number of open colectomies decreased significantly from Period 2 to Period 4 (46.1, 38.5, 33.4, p < 0.02). There was a significant increase in the number of laparoscopic procedures performed in each period among appendectomy (13.1, 28.3, 48.9, 58.4, all p < 0.02), colectomy (2.9, 10.1, 19.1, 23.4, all p < 0.01), and inguinal hernia repair (9.7, 14.9, 25.6, 34.1, all p < 0.01). CONCLUSION: The number of open procedures performed by general surgery residents continues to decline despite an increase in total cases reported. The reduction in open surgical experience may result in surgeons who lack technical skills to safely complete open procedures.

BACKGROUND: The increase in female surgeons has resulted in scrutiny of widely variable parental leave policies. We hypothesized that academic and private practice surgeons have different experiences based on difference in workplace expectations. METHODS: A 25-question survey was disseminated via social media and through the Association of Women Surgeons social media platforms from June 1 to September 15, 2017. An analysis of attending surgeons working in the USA in an academic or private practice setting was performed. RESULTS: Of 1115 total respondents, 477 were attending surgeons practicing in the USA. Practice distribution was 34% private and 47% academic. There was no difference in marital status, work status, or the number who report having been pregnant between the groups. Compared to academic surgeons, private practice surgeons were statistically less likely to have paid leave (p < 0.001) and were more likely to continue to pay benefits while on leave (p < 0.001). Private practitioners were more likely to return to work sooner than desired due to financial (p = 0.022) and supervisor (p = 0.004) pressures and were more likely to leave a job (p = 0.01). Academic surgeons were more likely to experience a delay in job advancement (p = 0.031). On multivariate analysis, more than two pregnancies were associated with an increased risk of perception of a bias and discrimination against pregnancy in the workplace. CONCLUSIONS: Parental leave policies and attitudes vary between academic and private practice, creating unique challenges for female surgeons and different issues for family planning depending on employment model.

BACKGROUND: Mentorship is a key component in preventing burnout and attrition in surgical training, yet many residencies lack a formal program, one method used to establish successful mentor relationships. We aimed to measure the difference in resident perceptions and experience after the implementation of a mentorship program. METHODS: An anonymous survey was distributed to all general surgery residents at a single academic institution before and after implementation of a year-long mentorship program that involved assigned mentors, two social events, and recommended mentorship meetings. Responses were recorded on a five-point Likert scale. RESULTS: Half of respondents (n = 17, 53%) attended at least one event, and 66% (n = 21) had at least one mentor meeting. The proportion of residents who identified a faculty mentor increased from 59% to 75%. Residents with two or more mentor meetings (n = 12, 38%) were more likely to report faculty were interested in mentoring and cared about their development (3.5 versus 4.6, 3.6 versus 4.6, P < 0.001). They were more likely to identify faculty approachable for resident performance (3.8 versus 4.6, P < 0.02) and outside of work concerns (3.2 versus 4.3, P < 0.01) and were more likely to be satisfied with the amount of mentorship received (2.8 versus 4.0 P < 0.001). CONCLUSIONS: Implementation of a formal mentorship program resulted in an improvement in resident perception of faculty involvement and support. Meeting with a mentor resulted in a significant improvement in resident perception. Implementation of a mentorship program can improve resident experience, and few interactions are needed to affect the change.

INTRODUCTION: Handoffs between the operating room (OR) and post-anesthesia care unit (PACU) require a high volume and quality of information to be transferred. This study aimed to improve perioperative communication with a handoff tool. METHODS: Perioperative staff at a quaternary care center was surveyed regarding perception of handoff quality, and OR to PACU handoffs were observed for structured criteria. A 25-item tool was implemented, and handoffs were similarly observed. Staff was then again surveyed. A multidisciplinary team led this initiative as a collaboration. RESULTS: After implementation, nursing reported improved perception of time spent (2.63-3.68, p = .02) and amount of information discussed (2.85-3.73, p = .05). Anesthesia also reported improved personal communication (3.69-4.43, p = .004), effectiveness of handoffs (3.43-3.82, p = .02), and amount of information discussed (4.26-4.76, p = .05). After implementation, observed patient information discussed during handoffs increased for both surgical and anesthesia team members. The frequency of complete and near-complete handoffs increased (40%-74%, p < .001). CONCLUSIONS: A structured handoff tool increased the amount of essential information reported during handoffs between the OR and PACU and increased team members' perception of handoffs.
