Room for Improvement: The Impact of Guideline-Recommended Extended Thromboprophylaxis in Patients Undergoing Abdominal Surgery for Colorectal and Anal Cancer at a Tertiary Referral Center.

BACKGROUND: Venous thromboembolism occurs in approximately 2% of patients undergoing abdominal and pelvic surgery for cancers of the colon, rectum, and anus and is considered preventable. The American Society of Colon and Rectal Surgeons recommends extended prophylaxis in high-risk patients, but there is low adherence to the guidelines. OBJECTIVE: This study aims to analyze the impact of venous thromboembolism risk-guided prophylaxis in patients undergoing elective abdominal and pelvic surgeries for colorectal and anal cancers from 2016 to 2021. DESIGN: This was a retrospective analysis. SETTING: The study was conducted at a multisite tertiary referral academic health care system. PATIENTS: Patients who underwent elective abdominal or pelvic surgery for colon, rectal, or anal cancer. MAIN OUTCOME MEASURES: Receipt of Caprini-guided venous thromboembolism prophylaxis, 90-day postoperative rate of deep vein thrombosis, pulmonary embolism, venous thromboembolism, and bleeding events. RESULTS: A total of 3504 patients underwent elective operations, of whom 2224 (63%) received appropriate thromboprophylaxis in the inpatient setting. In the postdischarged cohort of 2769 patients, only 2% received appropriate thromboprophylaxis and no thromboembolic events were observed. In the group receiving inappropriate thromboprophylaxis, at 90 days postdischarge, the deep vein thrombosis, pulmonary embolism, and venous thromboembolism rates were 0.60%, 0.40%, and 0.88%, respectively. Postoperative bleeding was not different between the 2 groups. LIMITATIONS: Limitations to our study include its retrospective nature, use of aggregated electronic medical records, and single health care system experience. CONCLUSION: Most patients in our health care system undergoing abdominal or pelvic surgery for cancers of the colon, rectum, and anus were discharged without appropriate Caprini-guided venous thromboembolism prophylaxis. Risk-guided prophylaxis was associated with decreased rates of inhospital and postdischarge venous thromboembolism without increased bleeding complications. See Video Abstract . MARGEN DE MEJORA EL IMPACTO DE LA TROMBOPROFILAXIS RECOMENDADA POR LAS DIRECTRICES EN PACIENTES SOMETIDOS A CIRUGA ABDOMINAL POR CNCER COLORRECTAL Y ANAL EN UN CENTRO DE REFERENCIA TERCIARIO: ANTECEDENTES:El tromboembolismo venoso ocurre en aproximadamente el 2% de los pacientes sometidos a cirugía abdominal y pélvica por cánceres de colon, recto y ano, y se considera prevenible. La Sociedad Estadounidense de Cirujanos de Colon y Recto recomienda una profilaxis prolongada en pacientes de alto riesgo, pero el cumplimiento de las directrices es bajo.OBJETIVO:Este estudio tiene como objetivo analizar el impacto de la profilaxis guiada por el riesgo de tromboembolismo venoso (TEV) en pacientes sometidos a cirugías abdominales y pélvicas electivas por cáncer colorrectal y anal entre 2016 y 2021.DISEÑO:Este fue un análisis retrospectivo.AJUSTE:El estudio se llevó a cabo en un sistema de salud académico de referencia terciaria de múltiples sitios.PACIENTES:Pacientes sometidos a cirugía abdominal o pélvica electiva por cáncer de colon, recto o ano.PRINCIPALES MEDIDAS DE RESULTADO:Recepción de profilaxis de tromboembolismo venoso guiada por Caprini, tasa postoperatoria de 90 días de trombosis venosa profunda, embolia pulmonar, tromboembolismo venoso y eventos de sangrado.RESULTADOS:Un total de 3.504 pacientes se sometieron a operaciones electivas, de los cuales 2.224 (63%) recibieron tromboprofilaxis adecuada en el ámbito hospitalario. En el cohorte de 2.769 pacientes después del alta, solo el 2% recibió tromboprofilaxis adecuada en la que no se observaron eventos tromboembólicos. En el grupo que recibió tromboprofilaxis inadecuada, a los 90 días después del alta, las tasas de trombosis venosa profunda, embolia pulmonar y tromboembolia venosa fueron del 0,60%, 0,40% y 0,88%, respectivamente. El sangrado posoperatorio no fue diferente entre los dos grupos.LIMITACIONES:Las limitaciones de nuestro estudio incluyen su naturaleza retrospectiva, el uso de registros médicos electrónicos agregados y la experiencia de un solo sistema de atención médica.CONCLUSIÓN:La mayoría de los pacientes en nuestro sistema de salud sometidos a cirugía abdominal o pélvica por cánceres de colon, recto y ano fueron dados de alta sin una profilaxis adecuada de TEV guiada por Caprini. La profilaxis guiada por el riesgo se asoció con menores tasas de tromboembolismo venoso hospitalario y dado de alta sin un aumento de las complicaciones de sangrado.

Comparative Outcomes of Robotic Versus Open Proctectomy for Rectal Cancer at High Risk of Positive Circumferential Resection Margin.

BACKGROUND: Concerns persist regarding the effectiveness of robotic proctectomy compared with open proctectomy for locally advanced rectal cancer with a high risk of circumferential resection margin involvement. OBJECTIVE: Comparison of surrogate cancer outcomes after robotic versus open proctectomy in this subpopulation. DESIGN: Retrospective cohort study. SETTING: Three academic hospitals (Mayo Clinic Arizona, Florida, and Rochester) with data available through the Mayo Data Explorer platform. PATIENTS: Patients at high risk of circumferential resection margin involvement were selected on the basis of the MRI-based definition from the MERCURY I and II trials. MAIN OUTCOME MEASURES: Rate of pathologic circumferential resection margin involvement (≤1 mm), mesorectal grading, and rate of distal margin involvement. RESULTS: Out of 413 patients, 125 (30%) underwent open and 288 (70%) underwent robotic proctectomy. Open proctectomy was significantly associated with a greater proportion of cT4 tumors (39.3% vs 24.8%, p = 0.021), multivisceral/concomitant resections (40.8% vs 18.4%, p < 0.001), and less frequent total neoadjuvant therapy use (17.1% vs 47.1%, p = 0.001). Robotic proctectomy was less commonly associated with pathologic circumferential resection margin involvement (7.3% vs 17.6%, p = 0.002), including after adjustment for cT stage, neoadjuvant therapy, and multivisceral resection (OR 0.326; 95% CI, 0.157-0.670, p = 0.002). Propensity score matching for 66 patients per group and related multivariable analysis no longer indicated any reduction of circumferential positive margin rate associated with robotic surgery ( p = 0.86 and p = 0.18). Mesorectal grading was comparable (incomplete mesorectum in 6% robotic proctectomy patients vs 11.8% open proctectomy patients, p = 0.327). All cases had negative distal resection margins. LIMITATION: Retrospective design. CONCLUSIONS: In patients with locally advanced rectal cancer at high risk of circumferential resection margin involvement, robotic proctectomy is an effective approach and could be pursued when technically possible as an alternative to open proctectomy.

RESULTADOS COMPARATIVOS ENTRE LA PROCTECTOMA ROBTICA Y LA PROCTECTOMA ABIERTA EN CASOS DE CNCER DE RECTO CON ALTO RIESGO DE MRGEN DE RESECCIN CIRCUNFERENCIAL POSITIVO: ANTECEDENTES:Persisten preocupaciones con respecto a la efectividad de la proctectomía robótica en comparación con la proctectomía abierta en casos de cáncer de recto localmente avanzado con un alto riesgo de margen de resección circunferencial positivo.OBJETIVO:Comparar los resultados en la subpoblación de portadores de cáncer luego de una proctectomía robótica versus una proctectomía abierta.DISEÑO:Estudio retrospectivo de cohortes.AJUSTE:Realizado en tres hospitales académicos (Mayo Clinic de Arizona, Florida y Rochester) a través de la plataforma Mayo Data Explorer.PACIENTES:Fueron seleccionados aquellos pacientes con alto riesgo de compromiso sobre el margen de resección circunferencial, según la definición de los Estudios Mercury I-II basada en la Imágen de Resonancia Magnética.MEDIDAS DE RESULTADO PRINCIPALES Y SECUNDARIAS:La tasa de compromiso patológico sobre el margen de resección circunferencial (≤1 mm), la clasificación mesorrectal y la tasa del compromiso del margen distal.RESULTADOS:De 413 pacientes, 125 (30%) fueron sometidos a una proctectomía abierta y 288 (70%) a proctectomía robótica. La proctectomía abierta se asoció significativamente con una mayor proporción de tumores cT4 (39,3% frente a 24,8%, p = 0,021), las resecciones multiviscerales/concomitantes fueron de 40,8% frente a 18,4%, p < 0,001 y una adminstración menos frecuente de terapia neoadyuvante total (17,1). % vs 47,1%, p = 0,001).La proctectomía robótica se asoció con menos frecuencia con la presencia de una lesión sobre el margen de resección circunferencial patológico (7,3% frente a 17,6%, p = 0,002), incluso después del ajuste por estadio cT, de la terapia neoadyuvante y de resección multivisceral (OR 0,326, IC 95% 0,157-0,670, p = 0,002). El apareado de propensión por puntuación en 66 pacientes por grupo y el análisis multivariable relacionado, no mostraron ninguna reducción en la tasa de margen positivo circunferencial asociado con la cirugía robótica ( p = 0,86 y p = 0,18). La clasificación mesorrectal fue igualmente comparable (mesorrecto incompleto en el 6% de los pacientes con RP frente al 11,8% de los pacientes con OP, p = 0,327). Todos los casos tuvieron márgenes de resección distal negativos.LIMITACIÓN:Diseño retrospectivo.CONCLUSIÓN:En pacientes con cáncer de recto localmente avanzado con alto riesgo de compromiso del margen de resección circunferencial, la proctectomía robótica es un enfoque eficaz y podría realizarse cuando sea técnicamente posible como alternativa a la proctectomía abierta.

Trends and Distribution of IPAAs in the United States: Becoming Harder to Find in Colon and Rectal Surgery Residency Training?

BACKGROUND: There has been concern among colon and rectal surgery residency programs in the United States that IPAA procedures have been decreasing, but evidence is limited. OBJECTIVE: The study aimed to evaluate the number of IPAAs performed by colon and rectal surgery residents in the United States and analyze the distribution of these cases on a national level. DESIGN: Retrospective. SETTINGS: The Accreditation Council for Graduate Medical Education Case Log National Data Reports were used to evaluate the number of IPAAs performed by residents from 2005 to 2021. The Nationwide Inpatient Sample database was used to identify all patients undergoing these procedures from 2005 to 2019. PATIENTS: All IPAA procedures regardless of indication. MAIN OUTCOME MEASURES: The primary outcome was the number of IPAAs performed by residents yearly. The secondary outcome was the national distribution of these procedures. RESULTS: Among colon and rectal surgery residents, case log data revealed an increase in mean and total number of IPAAs from 2005 to 2013, followed by a decline in both metrics after 2013. Despite the decrease, the mean number of cases per resident remained fewer than 6 between 2011 and 2021. A weighted national estimate of 48,532 IPAA patients were identified in the Nationwide Inpatient Sample database. A significant decrease was noted in the number of IPAAs after 2015 that persisted through 2019. There was a significant decrease in rural and urban nonteaching hospitals (from 2.1% to 1.6% and 25.6% to 4.3%, respectively; p < 0.001) and an increase in urbanteaching hospitals (from 72.4% to 94.1%; p < 0.001). LIMITATIONS: Nonrandomized retrospective study design. CONCLUSIONS: Despite the recent increase in the percentage of IPAAs performed at urban academic centers, there has been a decrease in cases performed by colon and rectal surgery residents. This can have significant implications for residents who graduate without adequate experience in performing this complex procedure independently, as well as training programs that may face challenges with maintaining accreditation.

El resultado secundario es la distribución nacional de estos procedimientos.RESULTADOS:Entre los residentes de cirugía de colon y recto, los datos de los registros de casos revelaron un aumento en el número medio y total de anastomosis anal con bolsa ileal de 2005 a 2013, seguido de una disminución en ambas métricas después de 2013. A pesar de la disminución, el número medio de casos por El residente permaneció >6 entre 2011 y 2021. Se identificó una estimación nacional ponderada de 48 532 pacientes con anastomosis anal con bolsa ileal en la base de datos de la Muestra Nacional de Pacientes Hospitalizados. Se observó una disminución significativa en el número de anastomosis anales con bolsa ileal después de 2015 que persistió hasta 2019. Hubo una disminución significativa en los hospitales no docentes rurales y urbanos (del 2,1% al 1,6% y del 25,6% al 4,3% respectivamente, p < 0,001) y un aumento en los hospitales universitarios urbanos (del 72,4% al 94,1%, p < 0,001).LIMITACIONES:Estudio retrospectivo no aleatorizado.CONCLUSIÓN:A pesar del reciente aumento en el porcentaje de anastomosis anal con bolsa ileal realizadas en centros académicos urbanos, ha habido una disminución en los casos realizados por residentes de cirugía de colon y recto. Esto puede tener implicaciones significativas para los residentes que se gradúan sin la experiencia adecuada en la realización de este complejo procedimiento de forma independiente, así como para los programas de capacitación que pueden enfrentar desafíos para mantener la acreditación.

The SAGES MASTERS program presents: the top 10 seminal articles for laparoscopic left and sigmoid colectomy pathway for uncomplicated disease.

BACKGROUND: As one of the 8 Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) Masters Program clinical pathways, the Colorectal Pathway aims to deliver educational content for the general surgeon organized along 3 levels of performance (competency, proficiency and mastery) each represented by an anchoring procedure. In this article, the SAGES Colorectal Task Force presents focused summaries of the top 10 seminal articles selected for laparoscopic left/sigmoid colectomy for uncomplicated disease. METHODS: Using a systematic literature search of Web of Science, the most cited articles on laparoscopic left and sigmoid colectomy were identified, reviewed, and ranked by members of the SAGES Colorectal Task Force. Additional articles not identified in the literature search were included if deemed impactful by expert consensus. The top 10 ranked articles were then summarized, including their findings, strengths and limitations with emphasis on relevance and impact in the field. RESULTS: The top 10 articles selected focus on variations in minimally invasive surgical techniques, video demonstrations, stratified approaches for benign and malignant disease as well as assessments of the learning curve. CONCLUSIONS: The selected top 10 seminal articles for laparoscopic left and sigmoid colectomy in uncomplicated disease are considered by the SAGES colorectal task force to be fundamental to the knowledge base of minimally invasive surgeons as they progress to mastery in these procedures.

Risk adjusted venous thromboembolism prophylaxis following pancreatic surgery.

This study analyzes pancreatectomy cases performed between 2016 and 2021 to determine the impact of using Caprini guideline indicated VTE prophylaxis on VTE and bleeding complications. This is a retrospective study of cases performed in a single academic health care system, in which Caprini score and VTE prevention measures were determined retroactively and prevention practices binarized as appropriate or not appropriate. Univariate and multivariate analyses were performed of 1,299 pancreatectomy case. Most patients were stratified as high risk for postoperative VTE. Receiving appropriate VTE prophylaxis during admission was associated with a 3-fold reduction in VTE complications (0.82% vs. 2.64%, p=0.01) without increasing bleeding complications. All VTE complications occurring with 30-day (1.2%) and 90-day (2.7%) from hospital discharged occurred in those not receiving appropriate prophylaxis, and discharged bleeding complications were also not associated with receivng appropriate discharged VTE prophylaxis. The findings our the study are significant as it highlights the ongoing need for standardization in VTE risk assessment and prevention measures to increase compliance to risk adjusted VTE prevention practice guidelines, thus reducing preventable VTE complications and potentially associated morbidity and mortality.

Continuous Glucose Monitoring for Patients with COVID-19 Pneumonia: Initial Experience at a Tertiary Care Center.

OBJECTIVE: Patients hospitalized with COVID-19 and hyperglycemia require frequent glucose monitoring, usually performed with glucometers. Continuous glucose monitors (CGMs) are common in the outpatient setting but not yet approved for hospital use. We evaluated CGM accuracy, safety for insulin dosing, and CGM clinical reliability in 20 adult patients hospitalized with COVID-19 and hyperglycemia. METHODS: Study patients were fitted with a remotely monitored CGM. CGM values were evaluated against glucometer readings. The CGM sensor calibration was performed if necessary. CGM values were used to dose insulin, without glucometer confirmation. RESULTS: CGM accuracy against glucometer, expressed as mean absolute relative difference (MARD), was calculated using 812 paired glucometer-CGM values. The aggregate MARD was 10.4%. For time in range and grades 1 and 2 hyperglycemia, MARD was 11.4%, 9.4%, and 9.1%, respectively, with a small variation between medical floors and intensive care units. There was no MARD correlation with mean arterial blood pressure levels, oxygen saturation, daily hemoglobin levels, and glomerular filtration rates. CGM clinical reliability was high, with 99.7% of the CGM values falling within the "safe" zones of Clarke error grid. After CGM placement, the frequency of glucometer measurements decreased from 5 to 3 and then 2 per day, reducing nurse presence in patient rooms and limiting viral exposure. CONCLUSION: With twice daily, on-demand calibration, the inpatient CGM use was safe for insulin dosing, decreasing the frequency of glucometer fingersticks. For glucose levels >70 mg/dL, CGMs showed adequate accuracy, without interference from vital and laboratory values.

Caprini assessment utilization and impact on patient safety in gynecologic surgery.

PURPOSE: Postoperative venous thromboembolism (VTE) can potentially be associated with significant morbidity, mortality, and healthcare costs. The aim of this study was to determine the utilization of Caprini guideline indicated VTE in elective gynecologic surgery patients and its impact on postoperative VTE and bleeding complications. METHODS: This was a retrospective cohort study of elective gynecologic surgical procedures performed between January 1, 2016, and May 31, 2021. Two study cohorts were generated: (1) those who received and (2) those who did not receive VTE prophylaxis based on Caprini score risk stratification. Outcome measures were then compared between the study cohorts and included the development of a VTE up to 90-days postoperatively. Secondary outcome measures included postoperative bleeding events. RESULTS: A total of 5471 patients met inclusion criteria and the incidence of VTE up to 90 days postoperatively was 1.04%. Overall, 29.6% of gynecologic surgery patients received Caprini score-based guideline VTE prophylaxis. 39.2% of patients that met high-risk VTE criteria (Caprini > 5) received appropriate Caprini score-based prophylaxis. In multivariate regression analysis, the American Society of Anesthesiologists (ASA) score (OR 2.37, CI 1.27-4.45, p < 0.0001) and Caprini score (OR 1.13, CI 1.03-1.24, p = 0.008) predicted postoperatively VTE occurrence. Increasing Charlson comorbidity score (OR 1.39, CI 1.31-1.47, P < 0.001) ASA score (OR 1.36, CI 1.19-1.55, P < 0.001) and Caprini score (OR 1.10, CI 1.08-1.13, P < 0.001) were associated with increased odds of receiving appropriate inpatient VTE prophylaxis. CONCLUSION: While the overall incidence of VTE was low in this cohort, enhanced adherence to risk-based practice guidelines may provide more patient benefit than harm to postoperative gynecologic patients.

Re-resection of Microscopically Positive Margins Found on Intraoperative Frozen Section Analysis Does Not Result in a Survival Benefit in Patients Undergoing Surgery and Intraoperative Radiation Therapy for Locally Recurrent Rectal Cancer.

BACKGROUND: Intraoperative frozen-section analysis provides real-time margin resection status that can guide intraoperative decisions made by the surgeon and radiation oncologist. For patients with locally recurrent rectal cancer undergoing surgery and intraoperative radiation therapy, intraoperative re-resection of positive margins to achieve negative margins is common practice. OBJECTIVE: This study aimed to assess whether re-resection of positive margins found on intraoperative frozen-section analysis improves oncologic outcomes. DESIGN: This is a retrospective cohort study. SETTINGS: This study was an analysis of a prospectively maintained multicenter database. PATIENTS: All patients who underwent surgical resection of locally recurrent rectal cancer with intraoperative radiation therapy between 2000 and 2015 were included and followed for 5 years. Three groups were compared: initial R0 resection, initial R1 converted to R0 after re-resection, and initial R1 that remained R1 after re-resection. Grossly positive margin resections (R2) were excluded. MAIN OUTCOME MEASURES: The primary outcome measures were 5-year overall survival, recurrence-free survival, and local re-recurrence. RESULTS: A total of 267 patients were analyzed (initial R0 resection, n = 94; initial R1 converted to R0 after re-resection, n = 95; initial R1 that remained R1 after re-resection, n = 78). Overall survival was 4.4 years for initial R0 resection, 2.7 years for initial R1 converted to R0 after re-resection, and 2.9 years for initial R1 that remained R1 after re-resection ( p = 0.01). Recurrence-free survival was 3.0 years for initial R0 resection and 1.8 years for both initial R1 converted to R0 after re-resection and initial R1 that remained R1 after re-resection ( p ≤ 0.01). Overall survival did not differ for patients with R1 and re-resection R1 or R0 ( p = 0.62). Recurrence-free survival and freedom from local re-recurrence did not differ between groups. LIMITATIONS: This study was limited by the heterogeneous patient population restricted to those receiving intraoperative radiation therapy. CONCLUSIONS: Re-resection of microscopically positive margins to obtain R0 status does not appear to provide a significant survival advantage or prevent local re-recurrence in patients undergoing surgery and intraoperative radiation therapy for locally recurrent rectal cancer.

La supervivencia global fue de 4,4 años para la resección inicial R0, 2,7 años para la R1 inicial convertida en R0 después de la re-resección y 2,9 años para la R1 inicial que permaneció como R1 después de la re-resección ( p = 0,01). La supervivencia libre de recurrencia fue de 3,0 años para la resección inicial R0 y de 1,8 años para el R1 inicial convertido en R0 después de la re-resección y el R1 inicial que permaneció como R1 después de la re-resección ( p ≤ 0,01). La supervivencia global no difirió para los pacientes con R1 y re-resección R1 o R0 ( p = 0,62). La supervivencia libre de recurrencia y la ausencia de recurrencia local no difirieron entre los grupos.LIMITACIONES:Población de pacientes heterogénea, restringida a aquellos que reciben radioterapia intraoperatoria.CONCLUSIONES:La re-resección de los márgenes microscópicamente positivos para obtener el estado R0 no parece proporcionar una ventaja de supervivencia significativa o prevenir la recurrencia local en pacientes sometidos a cirugía y radioterapia intraoperatoria para el cáncer de recto localmente recurrente.

Temporary vs. permanent stoma: factors associated with the development of complications and costs for rectal cancer patients.

OBJECTIVE: To compare in-hospital complication rates and treatment costs between rectal cancer patients receiving permanent and temporary stomas. Surgical complications and costs associated with permanent stoma formation are still poorly understood. While choosing between the two stoma options is usually based on clinical and technical factors, disparities exist. METHODS: Patients with rectal cancer, stoma formation, complications, and cost of care were identified from the Florida Agency for Health Care Administration Discharge Database. Rectal cancer patients who underwent elective surgery and received a permanent or temporary stoma were identified using ICD-10 codes. Patients who underwent colostomy with resection were included in the "Permanent stoma" group, and those who underwent "resection with ileostomy" were included in the "temporary stoma" group. Multivariable models compared patients receiving temporary vs. permanent stomas. RESULTS: Regression models revealed no difference in the odds of having a complication between patients who obtained permanent versus temporary stoma (OR 0.96, 95% CI: 0.70-1.32). Further, after adjusting for the number of surgeries, demographic variables, socioeconomic and regional factors, comorbidities, and type of surgery, there was a significant difference between permanent and temporary stomas for rectal cancer (ß - 0.05, p = 0.03) in the log cost of creating a permanent stoma. CONCLUSION: Our findings suggest there are no differences associated with complications, and reduced cost for permanent compared to temporary stomas. Increased costs are also associated with receiving minimally invasive surgery. As a result, disparities associated with receipt of MIS could ultimately influence the type of stoma received.

Risk of malignancy and outcomes of surgically resected presacral tailgut cysts: A current review of the Mayo Clinic experience.

AIM: The aim of this study was to describe the surgical management, outcomes and risk of malignancy of presacral tailgut cysts. METHOD: A retrospective analysis of all patients who underwent resection of tailgut cyst at Mayo Clinic in Arizona, Florida and Minnesota between 2008 and 2020 was performed. Demographics, presentation, evaluation, surgical approach, postoperative complications, pathology and recurrence rates were reviewed. RESULTS: Seventy-three patients were identified (81% female) with a mean age of 45 years. Thirty-nine patients (53%) were symptomatic, most commonly with pelvic pain (26 patients). Digital rectal examination identified a palpable mass in 68%. Mean tumour size was 6 cm. Resection was primarily performed through a posterior approach (77%, n = 56), followed by a transabdominal approach (18%, n = 13) and a combined approach (5%, n = 4). Six patients underwent a minimally invasive resection (laparoscopic/robotic). Coccygectomy or distal sacrectomy was performed in 41 patients (56%). Complete resection was achieved in 94% of patients. Thirty-day morbidity occurred in 18% and was most commonly wound related; there was no mortality. Malignancy was identified in six patients (8%). For the 30 patients with follow-up greater than 1 year, the median follow-up was 39 months (range 1.0-11.1 years). Local recurrence was identified in three patients and distant metastatic disease in one patient. CONCLUSION: The rate of malignancy in presacral tailgut cysts based on this current review was 8%. Overall recurrence was 5% at a median of 24 months.

Robotic Surgery for Rectal Cancer Provides Advantageous Outcomes Over Laparoscopic Approach: Results From a Large Retrospective Cohort.

OBJECTIVE: To compare short term outcomes of patients undergoing laparoscopic or robotic rectal cancer surgery. BACKGROUND: Significant benefits of robotic rectal cancer surgery over laparoscopy have yet to be demonstrated. Operative time and direct institutional cost seem in favor of the laparoscopic approach. METHODS: We performed a retrospective review of consecutive patients operated on for rectal cancer with a mini-invasive approach at Mayo Clinic from 2005 to 2018. The primary aim of this study was to investigate the difference in postoperative morbidity between the laparoscopic and robotic approach. Multivariable models for odds to complications and prolonged (≥6 days) length of stay were built. RESULTS: A total of 600 patients were included in the analysis. The number of patients undergoing robotic surgery was 317 (52.8%). The 2 groups were similar in respect to age, sex, and body mass index. Laparoscopic surgery was correlated to shorter operative time (214 vs 324 minutes; P < 0.001). Patients undergoing robotic surgery had a lower overall complications rate (37.2% vs 51.2%; P < 0.001). Robotic surgery was found to be the most protective factor [odds ratio (OR) 0.485; P = 0.006] for odds to complications. The event of a complication (OR 9.33; P < 0.001) and conversion to open surgery (OR 3.095; P = 0.002) were identified as risk factors for prolonged length of stay whereas robotic surgery (OR 0.62; P = 0.027) was the only independent protective factor. CONCLUSIONS: Robotic rectal cancer surgery is strongly associated with better short-term outcomes over laparoscopic surgery.

The intersection of tumor location and combined bowel preparation: Utilization differs but anastomotic leak risk reduction does not.

BACKGROUND AND OBJECTIVE: Whether bowel preparation utilization rates or effectiveness varies based on tumor location is unknown. METHODS: The 2012-2016 American College of Surgeons National Surgical Quality Improvement Program Colectomy Targeted participant user file was queried for patients undergoing elective colorectal resection for cancer. Bowel preparation was classified as combined, mechanical bowel preparation alone, oral antibiotic alone, or none. Cochran-Armitage tests were used for trend analysis. Multivariable analyses stratified by tumor location were performed for the outcome of anastomotic leak. An additional multivariable model including all tumor locations assessed for interaction between bowel preparation and tumor location on an anastomotic leak. RESULTS: A total of 29,739 operations were included and the anastomotic leak rate was 1.9% with combined preparation versus 4.0% without preparation. Combined bowel preparation utilization increased over time as tumor location became more distal (both p < .0001). However, the adjusted effect of combined bowel preparation on anastomotic leak risk reduction did not differ by individual tumor location or across all tumor locations (p = .43 for interaction). CONCLUSION: Though the utilization rate of combined bowel preparation increased as tumor location became more distal, its risk-reducing effect remained similar. Quality improvement initiatives should focus on increased utilization of combined bowel preparation with an emphasis on tumors in the ascending colon.

Influence of surgeon specialty and volume on the utilization of minimally invasive surgery and outcomes for colorectal cancer: a retrospective review.

BACKGROUND: Utilization of minimally invasive surgery (MIS) has multiple determinants, one being the specialization of the surgeon. The purpose of this study was to assess the differences in the utilization of MIS, associated length of stay (LOS), and complications for colorectal cancer between colorectal (CRS) and general surgeons (GS). Previous studies have documented the influence of surgical volume and surgeon specialty on clinical outcomes and patient survival following colorectal cancer surgery. It is unclear whether there are differences in the utilization of MIS for colorectal cancer based on surgeon's specialization and how this influences clinical outcomes. METHODS: Using the 2013-2015 Florida Inpatient Discharge Dataset and the National Plan & Provider Enumeration System, colorectal cancer patients experiencing a colorectal surgery were identified as well as the operating physician's specialty. Mixed-effects regression models were used to identify associations between the use of MIS, complications during the hospital stay, and patient LOS with patient, physician, and hospital characteristics. RESULTS: There is no difference in the use of MIS, complication, nor LOS between GS and CRS for colorectal cancer surgery. However, physician volume was associated with increased use of MIS (OR 1.26, 95% CI 1.09, 1.46) and MIS was associated with decreases in certain complications as well as reductions in LOS overall (ß = - 0.16, p < 0.001) and for each specialty (GS: ß = - 0.18, p < 0.001; CRS ß = - 0.12, p < 0.001) CONCLUSIONS: Despite the higher amount of proctectomies performed by CRS, no difference in MIS utilization, complication rate, or LOS was found for colorectal cancer patients based on surgeon specialty. While there are some differences in clinical outcomes attributable to specialized training, results from this study indicate that differences in surgical approach (MIS vs. Open), as well as the patient populations encountered by these two specialties, are key factors in the outcomes observed.

Permanent stoma: a quality outcome in treatment of rectal cancer and its impact on length of stay.

BACKGROUND: This study aimed to identify socioeconomic predictors of permanent stoma in rectal cancer treatment and examine its association with length of stay at the treatment facility. METHODS: Rectal cancer patients who underwent elective surgery between January 2015 and December 2018 were identified from the Agency for Health Care Administration Florida Hospital Inpatient Discharge Dataset. Multivariate regression models were utilized to identify demographic and socioeconomic factors associated with receiving a permanent stoma as well as the associated length of stay of these patients. RESULTS: Of 2630 rectal cancer patients who underwent surgery for rectal cancer, 21% had a permanent stoma. The odds of receiving permanent stoma increased with higher Elixhauser score, metastatic disease, advanced age, having open surgery, residence in Southwest Florida, and having Medicaid insurance or no insurance/self-payers (p < 0.05). Patients with a permanent stoma had a significantly extended stay after surgery (p < 0.001). CONCLUSIONS: Patients with a permanent stoma following cancer resection were more likely to have open surgery, had more comorbidities, and had a longer length of stay. Having permanent stoma was higher in patients living in South West Florida, patients with Medicaid insurance, and in the uninsured. Additionally, the payer type significantly affected the length of stay.

Factors Associated With Minimally Invasive Surgery for Colorectal Cancer in Emergency Settings.

BACKGROUND: Minimally invasive surgery (MIS) is associated with improved colorectal cancer (CRC) outcomes, but it is used less frequently in emergency settings. We aimed to assess patient-level factors associated with emergency presentation for CRC and the use of MIS in emergency versus elective settings. METHODS: This retrospective study examined the clinical data of patients who underwent emergency and elective resections for CRC from 2013 to 2015 using the Florida Inpatient Discharge Dataset. Multivariable analyses were performed to assess differences in gender, age, race, urbanization, region, insurance, and clinical characteristics associated with mode of presentation and surgical approach. In-hospital mortality and length of stay by mode of presentation were recorded. RESULTS: Of 16,277 patients identified, 10,224 (61%) had elective surgery and 6503 (39%) had emergency surgery. Emergency presentations were more likely to be black (14.2% versus 9.5%), Hispanic (18.9% versus 15.4%), Medicaid-insured (9.7% versus 4.2%), and have metastatic cancer (34.4% versus 20.2%) or multiple comorbidities (12.6% versus 4.0%). MIS was the surgical approach in 31.8% of emergency cases versus 48.1% of elective cases. Factors associated with lower odds of MIS for emergencies include Medicaid (odds ratio (OR) 0.79, 95% confidence interval (CI) 0.63-0.99), metastases (OR 0.56, CI 0.5-0.63), and multiple comorbidities (OR 0.53, CI 0.4-0.7). Emergency cases experienced higher in-hospital mortality (3.7% versus 1.0%) and a longer median length of stay (10 d versus 5 d). CONCLUSIONS: Emergency CRC presentations are associated with racial minorities, Medicaid insurance, metastatic disease, and multiple comorbidities. Odds of MIS in emergency settings are lowest for patients with Medicaid insurance and highest clinical disease burden.

Factors Influencing Colon and Rectal Surgery Residency Program Selection.

BACKGROUND: Little information exists to help colon and rectal surgery residency programs determine which factors applicants find important when selecting a training program. Our aim was to identify factors applicants find pertinent in the selection of their desired colon and rectal surgery residency program. METHODS: After the 2016 and 2017 National Resident Matching Program (The Match), a 58-question anonymous web-based survey was sent to all trainees who applied to our colon and rectal surgery residency program to determine factors applicants find important in selecting colon and rectal surgery residency training programs. RESULTS: Of 196 invitation emails sent, a total of five were returned with unidentifiable addresses leaving 191 surveys for possible completion. The survey response rate was 62.8% (n = 120). The top 10 areas identified as strongly to moderately influential in residency program selection included faculty experience, balanced training, operative volume, operative complexity, autonomy, faculty reputation, employment opportunities, Accreditation Council for Graduate Medical Education index case volumes, office/clinic complexity, and current resident/fellow input. CONCLUSIONS: Multiple elements were identified as strongly to moderately influential when selecting a training program. Training programs can use these named factors for resident recruitment, development, and self-assessment.

Trends and outcomes of sphincter-preserving surgery for rectal cancer: a national cancer database study.

PURPOSE: Previous studies have shown that sphincter-preserving surgery is associated with better quality of life in postsurgical rectal cancer patients. However, the factors predicting the likelihood of undergoing sphincter-preserving surgery have not been well-described. The aim of this study was to report the factors that determined the likelihood of undergoing sphincter-preserving surgery. METHODS: Characteristics of 24,018 rectal cancer patients undergoing sphincter-preserving surgery and abdominoperineal resection diagnosed from 2008 to 2012 from the National Cancer Database were investigated retrospectively for rate, pattern, and differences in mortality. Cox proportional hazards models were used to calculate hazard ratios for assessing mortality. Odds ratios were calculated using logistic regressions models for outcome sphincter-preserving surgery. RESULTS: Eighteen thousand four hundred fifty-two (77%) patients had sphincter-preserving surgery. Majority of sphincter-preserving surgery patients were aged < 70 (74%), had private insurance (52%), and got treatment at a comprehensive community cancer program (54%). Multivariable analysis showed that patients with age ≥ 70 (OR 0.87, 95% CI 0.80-0.95), male gender (OR 0.90, 95% CI 0.84-0.96), having Medicare (OR 0.83, 95% CI 0.76-0.90), Medicaid (OR 0.72, 95% CI 0.63-0.81), and poorly differentiated grade (OR 0.78, 95% CI 0.71-0.85) were less likely to undergo sphincter-preserving surgery. Multivariable analysis showed that patients having abdominoperineal resection have higher likelihood of mortality than sphincter-preserving surgery (HR 1.26, 95% CI 1.16-1.36). CONCLUSIONS: We were able to identify several patient and tumor-related factors impacting the likelihood of undergoing sphincter-preserving surgery. Patients undergoing non-sphincter sparing surgery had a higher mortality that sphincter preservation.

Surgical Care for Women with Endometrial Cancer in Florida.

Objective: The goal of this research was to analyze if disparities in route of hysterectomy for endometrial cancer exist in Florida. Materials and Methods: In this retrospective cohort study, Florida inpatient and ambulatory surgery databases (2014-2016) were examined to find cases of patients with endometrial cancer who underwent hysterectomy in the state. Logistic regression models were used to compare patient- and hospital-level factors associated with having minimally invasive surgery (MIS) versus open surgery, and complications in patients having open hysterectomy versus MIS. Results: Overall, 6513 patients met the inclusion criteria. MIS was performed in 81.4% of cases. The odds of using a minimally invasive approach to hysterectomy (vaginal, robotic, or laparoscopic) were significantly lower for black women (odds ratio [OR]: 0.41; 95% confidence interval [CI]: 0.34-0.50) as well as for other non-white patients (OR: 0.64; 95% CI: 0.49-0.84). Patients with Medicaid (OR: 0.42; 95% CI: 0.30-0.59) or Medicare managed care (OR: 0.73; 95% CI: 0.59-0.91), or who received care at a teaching hospital (OR: 0.82; 95% CI: 0.68-0.98) or government hospital (OR: 0.50; 95% CI: 0.38-0.65) were also less likely to receive MIS. Patients receiving care at a high-volume (OR: 1.69; 95% CI: 1.30-2.20) or medium-volume (OR: 3.11; 95% CI: 2.37-4.08) hospital, or patients who were located in the Central (OR: 1.71; 95% CI: 1.17-2.48) or Peninsula (OR: 1.73; 95% CI: 1.17-2.56) regions, compared to the Florida Panhandle, had greater odds of receiving MIS. Conclusions: Although Florida has a high adoption of MIS for treating endometrial cancer, disparities persist. Efforts of state-level entities should focus on improving access to minimally invasive hysterectomy for racial minorities with endometrial cancer.

ERAS protocol validation in a propensity-matched cohort of patients undergoing colorectal surgery.

PURPOSE: Enhanced recovery after surgery (ERAS) provides many benefits. However, important knowledge gaps with respect to specific components of enhanced recovery after surgery remain because of limited validation data. The aim of the study was to validate a mature ERAS protocol at a different hospital and in a similar population of patients. METHODS: This is a retrospective analysis of patients undergoing elective colorectal surgery from 2009 through 2016. Patients enrolled in ERAS are compared with those undergoing the standard of care. Patient demographic characteristics, length of stay, pain scores, and perioperative morbidity are described. RESULTS: Patients (1396) were propensity matched into two equal groups (ERAS vs non-ERAS). No significant difference was observed for age, Charlson Comorbidity Index, American Society of Anesthesiologists score, body mass index, sex, operative approach, and surgery duration. Median length of stay in ERAS and non-ERAS groups was 3 and 5 days (P < .001). Mean pain scores were lower in the ERAS group, measured at discharge from the postanesthesia unit (P < .001), on postoperative day 1 (P = .002) and postoperative day 2 (P = .02) but were identical on discharge. CONCLUSIONS: This ERAS protocol was validated in a similar patient population but at a different hospital. ERAS implementation was associated with an improved length of stay and pain scores similar to the original study. Different than most retrospective studies, propensity score matching ensured that groups were evenly matched. To our knowledge, this study is the only ERAS validation study in a propensity-matched cohort of patients undergoing elective colorectal surgery.

PROACTIVE PROTOCOL-BASED MANAGEMENT OF HYPERGLYCEMIA AND DIABETES IN COLORECTAL SURGERY PATIENTS.

OBJECTIVE: The management of diabetic patients undergoing elective abdominal surgery continues to be unsystematic, despite evidence that standardized perioperative glycemic control is associated with fewer postoperative surgical complications. We examined the efficacy of a pre-operative diabetes optimization protocol implemented at a single institution in improving perioperative glycemic control with a target blood glucose of 80 to 180 mg/dL. METHODS: Patients with established and newly diagnosed diabetes who underwent elective colorectal surgery were included. The control group comprised 103 patients from January 1, 2011, through December 31, 2013, before protocol implementation. The glycemic-optimized group included 96 patients following protocol implementation from January 1, 2014, through July 31, 2016. Data included demographic information, blood glucose levels, insulin doses, hypoglycemic events, and clinical outcomes (length of stay, re-admissions, complications, and mortality). RESULTS: Patients enrolled in the glycemic optimization protocol had significantly lower glucose levels intra-operatively (145.0 mg/dL vs. 158.1 mg/dL; P = .03) and postoperatively (135.6 mg/dL vs. 145.2 mg/dL; P = .005). A higher proportion of patients enrolled in the protocol received insulin than patients in the control group (0.63 vs. 0.48; P = .01), but the insulin was administered less frequently (median [interquartile range] number of times, 6.0 [2.0 to 11.0] vs. 7.0 [5.0 to 11.0]; P = .04). Two episodes of symptomatic hypoglycemia occurred in the control group. There was no difference in clinical outcomes. CONCLUSION: Improved peri-operative glycemic control was observed following implementation of a standardized institutional protocol for managing diabetic patients undergoing elective colorectal surgery.
