RESUMEN
BACKGROUND: Despite the established National Institute of Health Revitalization Act, which aims to include ethnic and racial minority representation in surgical trials, racial and ethnic enrollment disparities persist. OBJECTIVE: To assess the proportion of patients from minority races and ethnicities that are included in colorectal cancer surgical trials and reporting characteristics. DATA SOURCES: Search was performed using MEDLINE (Ovid), Embase, Web of Science, and Cochrane Central. STUDY SELECTION: Inclusion criteria included 1) trials performed in the United States between January 1, 2000, and May 30, 2022; 2) patients with colorectal cancer diagnosis; and 3) surgical intervention, technique, or postoperative outcome. Trials evaluating chemotherapy, radiotherapy, or other nonsurgical interventions were excluded. INTERVENTIONS: Pooled proportion and regression analysis was performed to identify the proportion of patients by race and ethnicity included in surgical trials and the association of year of publication and funding source. MAIN OUTCOME MEASURES: Proportion of trials reporting race and ethnicity and proportion of participants by race and ethnicity included in surgical trials. RESULTS: We screened 10,673 unique publications, of which 80 were examined in full text. Fifteen studies met our inclusion criteria. Ten (66.7%) trials did not report race, 3 reported races as a proportion of White participants only, and 3 reported 3 or more races. There was no description of ethnicity in 11 (73.3%) trials, with 2 describing "non-Caucasian" as ethnicity and 2 describing only Hispanic ethnicity. Pooled proportion of White participants was 81.3%, of Black participants was 6.2%, of Asian participants was 3.6%, and of Hispanic participants was 3.5%. LIMITATIONS: A small number of studies was identified that reported racial or ethnic characteristics of their participants. CONCLUSIONS: Both race and ethnicity are severely underreported in colorectal cancer surgical trials. To improve outcomes and ensure the inclusion of vulnerable populations in innovative technologies and novel treatments, reporting must be closely monitored.

BACKGROUND: Rectal prolapse (RP) typically presents in the elderly, though it can present in younger patients lacking traditional risk factors. The current study compares medical and mental health history, presentation, and outcomes for young and older patients with RP. METHODS: This is a single-center retrospective review of patients who underwent abdominal repair of RP between 2005 and 2019. Individuals were dichotomized into two groups based on age greater or less than 40 years. RESULTS: Of 156 patients, 25 were < 40. Younger patients had higher rates of diagnosed mental health disorders (80% vs 41%, p < 0.001), more likely to take SSRIs (p = .02), SNRIs (p = .021), anxiolytics (p = 0.033), and antipsychotics (p < 0.001). Younger patients had lower preoperative incontinence but higher constipation. Both groups had low rates of recurrence (9.1% vs 11.6%, p = 0.73). CONCLUSIONS: Young patients with RP present with higher concomitant mental health diagnoses and represent unique risk factors characterized by chronic straining compared to pelvic floor laxity.

BACKGROUND: In patients with ulcerative colitis who undergo IPAA, a diverting ileostomy is used to diminish the severity of anastomotic complications. Typically, the ileostomy is closed after an interval of 2 to 4 months. The safety of earlier closure of the ileostomy after pouch surgery is unknown. OBJECTIVE: This study aimed to compare postoperative outcomes in patients randomly assigned to early (7-12 days) or late (≥8 weeks) ileostomy closure after ileal pouch construction. DESIGN: This was a multicenter, prospective randomized trial. SETTING: The study was conducted at colorectal surgical units at select United States hospitals. PATIENTS: Adults with ulcerative colitis who underwent 2- or 3-stage proctocolectomy with IPAA were included. MAIN OUTCOME MEASURES: The primary outcomes included Comprehensive Complication Index at 30 days after ileostomy closure. The secondary outcomes included complications, severe complications, reoperations, and readmissions within 30 days of ileostomy closure. RESULTS: The trial was stopped after interim analysis because of a high rate of complications after early ileostomy closure. Among 36 patients analyzed, 1 patient (3%) had unplanned proctectomy with end-ileostomy. Of the remaining 35 patients, 28 patients (80%) were clinically eligible for early closure and underwent radiologic assessment. There were 3 radiologic failures. Of the 25 remaining patients, 22 patients (88%) were randomly assigned to early closure (n = 10) or late closure (n = 12), and 3 patients were excluded. Median Comprehensive Complication Index was 14.8 (0-54) and 0 (0-23) after early and late closure (p = 0.02). One or more complications occurred in 7 patients (70%) after early closure and in 2 patients (17%) after late closure (p = 0.01)' and complications were severe in 3 patients (30%) after early closure and 0 patients after late closure (p = 0.04). Reoperation was required in 1 patient (10%) and 0 patients (p = 0.26) after early closure and readmission was required in 7 patients (70%) and 1 patient (8%) after late closure (p = 0.003). LIMITATIONS: This study was limited by early study closure and selection bias. CONCLUSIONS: Early closure of a diverting ileostomy in patients with ulcerative colitis who underwent IPAA is associated with an unacceptably high rate of complications.

ALTA TASA DE COMPLICACIONES DESPUS DEL CIERRE PRECOZ DE LA ILEOSTOMA TERMINACIN TEMPRANA DEL ENSAYO ALEATORIZADO DE INTERVALO CORTO VERSUS LARGO PARA LA REVERSIN DE LA ILEOSTOMA EN ASA DESPUS DE LA CIRUGA DE RESERVORIO ILEAL: ANTECEDENTES:En los pacientes con colitis ulcerosa que se someten a una anastomosis del reservorio ileoanal, se utiliza una ileostomía de derivación para disminuir la gravedad de las complicaciones de la anastomosis. Por lo general, la ileostomía se cierra después de un intervalo de 2 a 4 meses. Se desconoce la seguridad del cierre más temprano de la ileostomía después de la cirugía de reservorio.OBJETIVO:Comparar los resultados posoperatorios en pacientes asignados al azar al cierre temprano (7-12 días) o tardío (≥ 8 semanas) de la ileostomía después de la construcción de un reservorio ileal.DISEÑO:Este fue un ensayo aleatorizado prospectivo multicéntrico.ESCENARIO:El estudio se realizó en unidades quirúrgicas colorrectales en hospitales seleccionados de los Estados Unidos.PACIENTES:Se incluyeron adultos con colitis ulcerosa que se sometieron a proctocolectomía en 2 o 3 tiempos con anastomosis ileoanal con reservorio.PRINCIPALES MEDIDAS DE RESULTADO:Los resultados primarios incluyeron el Índice Integral de Complicaciones a los 30 días después del cierre de la ileostomía. Los resultados secundarios incluyeron complicaciones, complicaciones graves, reoperaciones y readmisiones dentro de los 30 días posteriores al cierre de la ileostomía.RESULTADOS:El ensayo se detuvo después del análisis interino debido a una alta tasa de complicaciones después del cierre temprano de la ileostomía. Entre los 36 pacientes analizados, 1 (3%) tuvo una proctectomía no planificada con ileostomía terminal. De los 35 pacientes restantes, 28 (80%) fueron clínicamente elegibles para el cierre temprano y se sometieron a una evaluación radiológica. Hubo 3 fracasos radiológicos. De los 25 pacientes restantes, 22 (88 %) se asignaron al azar a cierre temprano (n = 10) o tardío (n = 12) y 3 fueron excluidos. La mediana del Índice Integral de Complicaciones fue de 14,8 (0-54) y 0 (0-23) después del cierre temprano y tardío (p = 0,02). Una o más complicaciones ocurrieron en 7 pacientes (70%) después del cierre temprano y 2 (17%) pacientes después del cierre tardío (p = 0,01) y fueron graves en 3 (30%) y 0 pacientes, respectivamente (p = 0,04). Requirieron reintervención en 1 (10%) y 0 (p = 0,26) y reingreso en 7 (70%) y 1 (8%) pacientes (p = 0,003).LIMITACIONES:Este estudio estuvo limitado por el cierre temprano del estudio; sesgo de selección.CONCLUSIONES:El cierre temprano de una ileostomía de derivación en pacientes con colitis ulcerosa con anastomosis de reservorio ileoanal se asocia con una tasa inaceptablemente alta de complicaciones.

Though rates of colorectal cancer (CRC) screening continue to improve with increased advocacy and awareness, there are numerous disparities that continue to be defined within different health systems and populations. We aimed to define associations between patients' socio-demographic characteristics and CRC screening in a well-resourced safety-net health system. A retrospective review was performed from 2018 to 2019 of patients between 50 and 75-years-old who had a primary care visit within the last two years. Numerous patient characteristics were extracted from the medical record, including self-reported race, self-reported ethnicity, insurance, preferred language, severe mental health diagnoses (SMHD), and substance use disorder (SUD). Multivariate logistic regression assessed characteristics associated with CRC screening. Of 22,145 included patients, 16,065 (72.5%) underwent CRC screening. <40% of the population was White or of North American/European ethnicity and 38% had limited English proficiency. Hispanic patients had the highest screening rate while White patients had the lowest among races (78.1% vs 68.5%, respectively). White patients had higher rates of SMHD and SUD (p < 0.001). In multivariable analysis, most other races (Black, Asian, and Hispanic), ethnicities, and languages had significantly higher odds of screening, ranging from 20% to 55% higher, when White, North American/European, English-speakers are used as reference. In a well-resourced safety-net health system, patients who were non-White, non-North American/European, and non-English-speaking, had higher odds of CRC screening. This data from a unique health system may better guide screening outreach and implementation strategies in historically under-resourced communities, leading to strategies for equitable colorectal cancer screening.

PURPOSE: Prior studies suggest postoperative C-reactive protein (CRP) trends are sensitive for predicting anastomotic leak (AL) after elective colorectal surgery. However, in the setting of enhanced recovery pathways, multi-day CRP trends may not be feasible. This study aimed to assess the realistic and clinical utility of CRP in prediction of AL. METHODS: A retrospective review of patients who underwent elective colectomy or proctectomy from January 2019 to October 2020 at a single institution was performed. Comorbidities, operative characteristics, and perioperative outcomes were recorded. CRP was checked routinely on POD1 and on a clinical basis subsequently. The association between 10-point change in CRP-POD1 and AL was evaluated using multivariable logistic regression. The relationships between CRP-POD3, CRP-POD1, and AL were assessed using exploratory analyses. RESULTS: Among 332 patients, 23 (6.9%) developed AL, of which 9 cases (39%) were diagnosed upon readmission. AL was not associated with mortality. Median length of stay was 3 days (IQR 2-5). Median days to AL diagnosis was 7 (IQR 4-15). Adjusting for diverting stoma, steroid use, diagnosis, and open surgery, each 10-point increase in CRP was associated with increased odds of AL (OR 1.12, 95% CI 1.03-1.21, p=0.008). CRP-POD1 had poor discriminant utility for detecting AL (AUC 0.62, 95% CI = 0.494-0.746; p=0.061). CONCLUSION: CRP on POD1 is not a reliable method to predict a leak, and trending CRP may not be practical with decreasing lengths of stay in colorectal surgery.

PURPOSE: Although not considered standard therapy, neoadjuvant chemotherapy (NAC) is an encouraging alternative for selected patients with locally advanced colon cancer (LAC). The aim of this study was to compare 30-day postoperative outcomes between patients undergoing upfront surgery and those undergoing NAC for LAC. METHODS: Using the ACS-NSQIP data from 2016 to 2020, 11,498 patients with LAC were divided into those who underwent upfront colectomy (96.2%) and those who received NAC (3.8%). The primary outcome was a composite outcome encompassing 30-day major postoperative complications. Propensity score matched (PSM) analysis and multivariable logistic regression were performed. RESULTS: After PSM analysis, there was no statistically significant difference in the development of a major complication. NAC was not significantly associated with the primary outcome. Risk factors for postoperative complications were T4 stage, older age, male sex, black race, smoking, dependent status, severe COPD, hypoalbuminemia, and preoperative transfusion. Laparoscopic and robotic surgery was protective. CONCLUSION: NAC did not increase the odds of developing a major complication.

BACKGROUND: The Tn antigen (CD175) is an O-glycan expressed in various types of human adenocarcinomas, including colorectal cancer (CRC), though prior studies have relied heavily upon poorly characterized in-house generated antibodies and lectins. In this study, we explored Tn expression in CRC using ReBaGs6, a well-characterized recombinant murine antibody with high specificity for clustered Tn antigen. METHODS: Using well-defined monoclonal antibodies, expression patterns of Tn and sialylated Tn (STn) antigens were characterized by immunostaining in CRC, in matched peritumoral [transitional margin (TM)] mucosa, and in normal colonic mucosa distant from the tumor, as well as in adenomas. Vicia villosa agglutinin lectin was used to detect terminal GalNAc expression. Histo-scoring (H scoring) of staining was carried out, and pairwise comparisons of staining levels between tissue types were performed using paired samples Wilcoxon rank sum tests, with statistical significance set at 0.05. RESULTS: While minimal intracellular Tn staining was seen in normal mucosa, significantly higher expression was observed in both TM mucosa (p < 0.001) and adenocarcinoma (p < 0.001). This pattern was reflected to a lesser degree by STn expression in these tissue types. Interestingly, TM mucosa demonstrates a Tn expression level even higher than that of the adenocarcinoma itself (p = 0.019). Colorectal adenomas demonstrated greater Tn and STn expression relative to normal mucosa (p < 0.001 and p = 0.012, respectively). CONCLUSIONS: In summary, CRC is characterized by alterations in Tn/STn antigen expression in neoplastic epithelium as well as peritumoral benign mucosa. Tn/STn antigens are seldom expressed in normal mucosa. This suggests that TM mucosa, in addition to CRC itself, represents a source of glycoproteins rich in Tn that may offer future biomarker targets.

BACKGROUND: Dose-intensified rescue therapy with infliximab for hospitalized patients with ulcerative colitis has become increasingly popular in recent years. However, there is ongoing debate about both the efficacy of these regimens to reduce the rate of colectomy and the associated risks of increased infliximab exposure. OBJECTIVE: The purpose of this study was to compare the colectomy and postoperative complication rates in hospitalized patients with severe ulcerative colitis receiving standard infliximab induction therapy (3 doses of 5 mg/kg at weeks 0, 2, and 6) and dose-intensified regimens including a higher weight-based dosing or more rapid interval. DESIGN: This was a retrospective cohort study. SETTINGS: This study was conducted at an academic tertiary care hospital. PATIENTS: A total of 145 adult patients received inpatient rescue infliximab therapy for the treatment of ulcerative colitis between 2008 and 2020. MAIN OUTCOME MEASURES: The primary outcome was colectomy rate within 3 months of rescue therapy. Secondary outcomes include mid-term colectomy rates, as well as perioperative complications in patients receiving colectomy within 3 months of rescue infliximab initiation. RESULTS: The proportion of dose-intensified regimens increased over time. Unadjusted 3-month colectomy rates were 14% in patients who received standard rescue infliximab dosing, 16% in patients given a single dose-escalated dose, and 24% in patients given multiple inpatient dose-escalated doses. These rates were not statistically significantly different. Of the patients requiring colectomy within 3 months of infliximab rescue, those who received multiple inpatient doses of dose-escalated therapy had a higher percentage of colectomy during the initial hospitalization but a lower rate of perioperative complications. LIMITATIONS: This study was limited by the use of retrospective data and the limited power to account for the heterogeneity of disease. CONCLUSIONS: No significant difference was found in colectomy rates between patients receiving standard or dose-intensified regimens. However, dose-intensified regimens, including multiple inpatient doses given to patients with more severe disease, were not associated with a greater risk of perioperative complications.

LA TERAPIA DE RESCATE CON DOSIS INTENSIFICADA DE INFLIXIMAB EN COLITIS ULCEROSA GRAVE NO REDUCE LAS TASAS DE COLECTOMA A CORTO PLAZO NI AUMENTA LAS COMPLICACIONES POSOPERATORIAS: ANTECEDENTES:La terapia de rescate de dosis intensificada con infliximab para pacientes hospitalizados con colitis ulcerosa se ha vuelto cada vez más popular en los últimos años. Sin embargo, existe un debate en curso sobre la eficacia de estos regímenes para reducir la tasa de colectomía y los riesgos asociados a una mayor exposición al infliximab.OBJETIVO:El propósito de este estudio fue comparar las tasas de colectomía y complicaciones posoperatorias en pacientes hospitalizados con colitis ulcerosa grave que recibieron terapia estándar de inducción de infliximab (3 dosis de 5 mg/kg en las semanas 0, 2, 6) y regímenes de dosis intensificada que incluyen una dosificación más alta basada en el peso o intervalo más rápido.DISEÑO:Fue un estudio de cohorte retrospectivo.ENTORNO CLÍNICO:Este estudio se realizó en un hospital académico de tercer nivel.PACIENTES:Un total de 145 pacientes adultos que recibieron terapia de rescate con infliximab para el tratamiento de la colitis ulcerosa entre 2008 y 2020.PRINCIPALES MEDIDAS DE VALORACIÓN:El resultado principal fue la tasa de colectomía dentro de los 3 meses posteriores a la terapia de rescate. Los resultados secundarios incluyen tasas de colectomía a mediano plazo, así como las complicaciones perioperatorias en pacientes que reciben colectomía dentro de los 3 meses posteriores al inicio de infliximab de rescate.RESULTADOS:La proporción de regímenes de dosis intensificada aumentó con el tiempo. Las tasas de colectomía de 3 meses no ajustadas fueron del 14% en los pacientes que recibieron dosis estándar de infliximab de rescate, del 16% en los pacientes que recibieron una dosis única escalonada y del 24% en los pacientes que recibieron múltiples dosis hospitalarias escalonadas. Estas tasas no fueron estadísticamente significativas. De los pacientes que requirieron colectomía dentro de los 3 meses posteriores al rescate de infliximab, aquellos que recibieron terapia de múltiples dosis hospitalarias escalonadas tuvieron un mayor porcentaje de colectomía durante la hospitalización inicial pero una menor tasa de complicaciones perioperatorias.LIMITACIONES:Datos retrospectivos y poder limitado para explicar la heterogeneidad de la enfermedad.CONCLUSIONES:No se encontraron diferencias significativas en las tasas de colectomía entre los pacientes que recibieron regímenes estándar o de dosis intensificada. Sin embargo, los regímenes de dosis intensificadas, incluidas múltiples dosis hospitalarias administradas a pacientes con enfermedad más grave, no se asociaron con un mayor riesgo de complicaciones perioperatorias.

BACKGROUND: Current standard of care for creation of small bowel anastomoses after a loop ileostomy reversal includes the use of stapler devices and sutures. Compression anastomosis devices have been used for decades, aimed toward improved outcomes with a "staple free" & "suture free" anastomosis. The self-forming magnet (SFM) device is a type of compression anastomosis device used to safely and effectively create an end-to-end small bowel anastomosis without the localized inflammatory response seen with sutures or staples, as no foreign bodies are left behind. METHODS: A Good Laboratory Practice preclinical study using a porcine model to evaluate creating an in vivo anastomosis via magnetic compression between two segments of small bowel (jejunum or ileum) was performed. Magnetic anastomoses were compared to stapled and handsewn anastomoses. Six animals were used for the magnetic anastomosis and eight for the two control groups for a total of 14 subjects. RESULTS: Mean creation times were 17.1 min (SD 6.06) for the SFM group, 10.3 min (SD 6.55, CI 95%) for the stapled anastomosis group, and 28.3 min (SD 2.63, CI 95%) for the suture anastomosis group, with a statistically significant difference among groups (p < 0.0021). All evaluated SFM anastomosis, stapled anastomosis, and handsewn anastomosis underwent a burst test with a pressure of 1.3 PSI. All six magnets used for anastomoses were naturally expelled. The range of days to expel magnets was 10-17 days. Intestinal anastomoses using magnets had considerably less residual scarring and intestinal distortion than anastomoses done with either suture or staples. CONCLUSION: This preclinical study documents the safety and efficacy of creating end-to-end small bowel anastomoses after ileostomy takedown using a magnetic compression device. The result is an anastomosis free of foreign objects with less inflammation, scarring, distortion, and mural thickening than seen in sutured or stapled anastomoses.

BACKGROUND: Health Industry and physician collaboration generates innovation. Colorectal Surgeon (CRS) selection to collaborate might not be random. We aim to identify CRS personal and professional characteristics that facilitate collaboration with the Industry. METHOD: Cross-sectional study of Industry payments to CRS (2014-2018) using Open Payments Database from Centers for Medicare & Medicaid Services. Multivariable regression compared variables predicting payment amount including gender, years in practice, leadership positions, H-index, Twitter presence and geographic location. RESULTS: Surgeons who were male received 3.1 times the amount in Industry payments as compared to females (p = 0.014). Chairs and Division Chiefs received 2.7 times the amount in payments as compared to those without these leadership positions (p = 0.003). Surgeons with an H-index ≥ 8 received 2.2 times the amount in payments as compared to those with H-index < 8 (p = 0.001). Surgeons in practice for 12-19 and 20-30 years received 3 times and 4.4 times the amount in payments as compared to surgeons in practice for 1-11 years (p = 0.036 and p = 0.017, respectively). Surgeons in the South received 3.2 times and 2 times the amount in payments as compared to surgeons in the Northeast (p < 0.0005) and in the Midwest (p = 0.006). Surgeons with Twitter accounts received 1.7 times the amount in payments as compared to surgeons without Twitter (p = 0.036). Among Twitter users, those with 321-17,200 followers received 4.7 times and 9.5 times the amount in payments as compared to those with 0-15 and 16-79 followers, respectively (p = 0.008 and p = 0.009). CONCLUSION: Industry payments are more commonly addressed to male, senior surgeons in leadership tracks with strong social media outreach. With the increasing gender and racial variety in the CRS field, it is expected that collaborations between industry and surgeons will become more diverse and inclusive.

BACKGROUND: In the setting of multidisciplinary standardized care of locally advanced rectal cancer, preoperative chemoradiotherapy and total mesorectal excision have become the mainstay treatment. OBJECTIVE: This study aimed to evaluate whether the lack of preoperative chemoradiotherapy or poor response to it is associated with higher radial margin disease involvement in patients with locally advanced rectal cancer. DESIGN: This is a retrospective cohort study using a publicly available database. SETTING: Data were collected from the proctectomy-targeted National Surgical Quality Improvement Project file from 2016 to 2017. PATIENTS: A total of 1161 patients were analyzed. They were categorized into 3 groups: patients who did not receive any preoperative chemoradiotherapy (28.6%), patients who received and responded to preoperative chemoradiotherapy (41.2%), and patients who received but did not respond to preoperative chemoradiotherapy (30.2%). MAIN OUTCOME MEASURES: Response to treatment was determined by using the American Joint Committee on Cancer pretreatment and final pathological staging. Circumferential radial margin was extracted from the targeted proctectomy file. RESULTS: Disease-involved positive circumferential radial margin was found in 86 (7.4%) cases. Positive radial margin was noted in 11 of 479 patients (2.3%) who underwent preoperative chemoradiotherapy and responded to treatment, 30 of 350 patients (8.6%) who did not respond or had a poor response to preoperative chemoradiotherapy, and 45 of 332 patients (13.6%) who did not receive preoperative chemoradiotherapy (p < 0.001). Regression analysis demonstrated that patients who do not receive preoperative chemoradiotherapy or have poor response to it have 6.6 and 4 times higher chances of having a positive radial margin. LIMITATIONS: There is a risk of selection bias, unidentified confounders, and missing data despite the use of a nationwide cohort. CONCLUSIONS: Omission of indicated preoperative chemoradiotherapy or poor response to it is associated with increased risk of radial margin positivity. More efforts are needed for standardized rectal cancer care with the appropriate use of preoperative chemoradiotherapy. See Video Abstract at http://links.lww.com/DCR/B467.

BACKGROUND: The emergency department plays a common and critical role in the treatment of postoperative patients. However, many quality improvement databases fail to record these interactions. As such, our understanding of the prevalence and etiology of postoperative emergency department visits in contemporary colorectal surgery is limited. Visits with potentially preventable etiologies represent a significant target for quality improvement, particularly in the current era of rapidly evolving postoperative and ambulatory care patterns. OBJECTIVE: We aimed to characterize postoperative emergency department visits and identify factors associated with these visits for potential intervention. DESIGN: This was a retrospective cohort study. SETTINGS: The study was conducted at an academic medical center. PATIENTS: Consecutive patients undergoing colectomy or proctectomy within the division of colorectal surgery at an academic medical center between 2014 and 2018 were included. MAIN OUTCOME MEASURES: Frequency and indication for emergency department visits, as well as clinical and sociodemographic factors associated with emergency department visits in the postoperative period, were included measures. RESULTS: From the 1763 individual operations, there were 207 emergency department visits from 199 patients (11%) within 30 days of discharge. Two thirds of emergency department visits led to readmission. Median (interquartile range) time to presentation was 8 days (4-16 d). Median time in the emergency department was 7.8 hours (6.0-10.1 h). One third of visits were identified as potentially preventable, most commonly for pain (17%) and stoma complications (excluding dehydration; 13%). A primary language other than English was associated with any postoperative emergency department visit risk ratio of 2.7 (95% CI, 1.3-5.3), as well as a preventable visit risk ratio of 3.6 (95% CI, 1.7-8.0). LIMITATIONS: This was a single-center study and a retrospective review. CONCLUSIONS: One third of emergency department visits after colorectal surgery are potentially preventable. Special attention should be directed toward those patients who do not speak English as a primary language. See Video Abstract at http://links.lww.com/DCR/B648. SE PUEDEN EVITAR LAS VISITAS AL SERVICIO DE URGENCIA DESPUS DE UNA CIRUGA COLORECTAL: ANTECEDENTES:Las unidades de emergencia tienen un rol fundamental en el periodo posterior a una cirugía. Sin embargo muchos de los registros en las bases de datos de estas secciones no son de buena calidad. Por esto analizar la prevalencia y etiología de las visitas postoperatorias en cirugía colorectal resulta ser bastante limitada. Para lograr una mejoría en la calidad es fundamental analizar las causas potencialmente evitables, especialmente al considerer la rapida evolucion de los parametros de medición actuales.OBJETIVO:Nuestro objetivo es caracterizar las visitas postoperatorias al servicio de urgencias e identificar los factores asociados potencialmente evitables.DISEÑO:Estudio de cohorte retrospectivo.AJUSTE:Centro médico académico, 2014-2018.PACIENTES:Pacientes consecutivos sometidos a colectomía o proctectomía dentro de la división de cirugía colorrectal en un centro médico académico entre 2014 y 2018.PRINCIPALES MEDIDAS DE RESULTADO:Frecuencia e indicación de las visitas al servicio de urgencias en el period postoperatorio: factores clínicos y sociodemográficos.RESULTADOS:De 1763 operaciones individuales, hubo 207 visitas al departamento de emergencias de 199 pacientes (11%) en los 30 días posteriores al alta. Dos tercios de las visitas al servicio de urgencias dieron lugar a readmisiones. La mediana [rango intercuartílico] de tiempo hasta la presentación fue de 8 [4-16] días. La mediana de tiempo en el servicio de urgencias fue de 7,8 [6-10,1] horas. Un tercio de las visitas se identificaron como potencialmente evitables, más comúnmente dolor (17%) y complicaciones del estoma (excluida la deshidratación) (13%). En los pacientes con poco manejo del inglés se asoció con una mayor frecuencia razón de visitas al departamento de emergencias posoperatorias [IC del 95%] 2,7 [1,3-5,3], así como opetancialmente evitables con un RR de 3,6 [1,7-8,0].LIMITACIONES:Estudio de un solo centro y revisión retrospectiva.CONCLUSIÓN:Al menos un tercio de las visitas al servicio de urgencias después de una cirugía colorrectal son potencialmente evitables. Se debe prestar especial atención a los pacientes que no hablan inglés como idioma materno. Consulte Video Resumen en http://links.lww.com/DCR/B648.

BACKGROUND: Relationships between high-volume surgeons and improved postoperative outcomes have been well documented. Colorectal procedures are often performed by general surgeons, particularly in emergent settings, and may form a large component of their practice. The influence of subspecialized training on outcomes after emergent colon surgery, however, is not well described. OBJECTIVE: The purpose of this study was to determine whether subspecialty training in colorectal surgery is associated with differences in postoperative outcomes after emergency colectomy. DESIGN: This was a retrospective cohort study. SETTINGS: Three tertiary care hospitals participating in the National Surgical Quality Improvement Project were included. PATIENTS: Patients undergoing emergent colon resections were identified at each institution and stratified by involvement of either a colorectal surgeon or a general or acute care surgeon. MAIN OUTCOME MEASURES: Propensity score matching was used to isolate the effect of surgeon specialty on the primary outcomes, including postoperative morbidity, mortality, length of stay, and the need for unplanned major reoperation, in comparable cohorts of patients. RESULTS: A total of 889 cases were identified, including 592 by colorectal and 297 by general/acute care surgeons. After propensity score matching, cases performed by colorectal surgeons were associated with significantly lower rates of 30-day mortality (6.7% vs 16.4%; p = 0.001), postoperative morbidity (45.0% vs 56.7%; p = 0.009), and unplanned major reoperation (9.7% vs 16.4%; p = 0.04). In addition, length of stay was ≈4.4 days longer among patients undergoing surgery by general/acute care surgeons (p < 0.001). LIMITATIONS: This study was limited by its retrospective design, with potential selection bias attributed to referral patterns. CONCLUSIONS: After controlling for underlying disease states and illness severity, emergent colon resections performed by colorectal surgeons were associated with significantly lower rates of postoperative morbidity and mortality when compared with noncolorectal surgeons. These findings may have implications for referral patterns for institutions. See Video Abstract at http://links.lww.com/DCR/A767.

The MarketScan databases are a family of administrative claims databases that contain data on inpatient and outpatient claims, outpatient prescription claims, clinical utilization records, and healthcare expenditures. The three main databases available for use are each composed of a convenience sample for one of the following patient populations: (1) patients with employer-based health insurance from contributing employers, (2) Medicare beneficiaries who possess supplemental insurance paid by their employers, and (3) patients with Medicaid in one of eleven participating states. Eleven supplemental databases are available, which are utilized to overcome the limited clinical data available in the core MarketScan databases. There are several limitations to this database, primarily related to the fact that individuals or their family members within two of the core databases mandatorily possess some form of employer-based health insurance, which prevents the dataset from being nationally representative. Nonetheless, this database provides detailed and rigorously maintained claims data to identify healthcare utilization patterns among this cohort of patients.
RESUMEN
BACKGROUND: The American Joint Committee on Cancer includes extranodal tumor deposits in the tumor-node-metastasis classification of colon cancer. However, it is unclear how tumor deposits compare with lymph node metastases in prognostic significance. This study evaluated the survival impact of tumor deposits relative to lymph node metastases in stage III colon cancer. METHODS: The US National Cancer Database (2010-2012) was reviewed for resectable stage III adenocarcinoma of the colon, and stratified by presence of tumor deposits and lymph node metastases. Univariate and multivariate survival analyses were performed. RESULTS: Of 6424, 10.1% had both tumor deposits and lymph node metastases [5-year survival (5YS) 40.2%], 2.5% had tumor deposits alone (5YS 68.1%), and 87.4% had lymph node metastases alone (5YS 55.4%). Patients with lymph node metastases alone tended to have a greater number of lymph nodes retrieved (20.9 versus 18.8, p = 0.0126) and were more likely to receive adjuvant therapy (66.9 vs 58.0%, p = 0.003) than those with only tumor deposits. Patients with both had significantly worse survival at all T stages (p < 0.05, all). There was no significant difference in survival between tumor deposits alone and lymph node metastases alone at any T stage (p > 0.8, all). After controlling for patient, disease, and treatment characteristics, patients with tumor deposits alone [hazard ratio (HR) 0.56, p = 0.001] or only lymph node metastases (HR 0.64, p < 0.001) were associated with improved survival relative to patients with both. CONCLUSIONS: Concomitant presence of tumor deposits and lymph node invasion carries poor prognostic significance. Tumor deposits alone appear to have prognostic implications similar to lymph node invasion alone.

BACKGROUND: Endoscopic mucosal resection comprises the first-line treatment for large cecal polyps. With up to 14% of unresectable colonic polyps harboring malignancy, the management of endoscopically unresectable cecal polyps remains an oncologic right hemicolectomy, which can be associated with substantial postoperative morbidity. OBJECTIVE: This study compares the outcomes of patients with cecal polyps who underwent either endoscopic mucosal resection, a cecectomy, or a right hemicolectomy. DATA SOURCES: Patients undergoing either endoscopic mucosal resection, partial cecectomy, or right hemicolectomy from 2008 to 2017 at a single tertiary care institution were selected. STUDY SELECTION: This was a retrospective cohort study. MAIN OUTCOME MEASURES: The primary outcomes measured were the rate of malignancy, complication rate, estimated blood loss, and hospital length of stay between surgical cohorts. RESULTS: One hundred twenty-nine patients with cecal polyps were identified, of which 52 were referred for surgery. Nineteen underwent partial cecectomy and 33 (27.3%) underwent right hemicolectomy. Two patients undergoing cecectomy required conversion to hemicolectomy because the resected specimen did not contain the polyp. The 2 surgical cohorts did not differ significantly regarding age, sex, or ASA classification. Procedural complication rates were higher among those undergoing hemicolectomy compared with those undergoing cecectomy (37.1% versus 5.9%, p = 0.02). Estimated blood loss (50 vs 10 mL, p = 0.02), operative duration (98 vs 76 minutes, p = 0.009), and length of stay (4 vs 2 days, p < 0.001) were higher in patients undergoing hemicolectomy than in those undergoing cecectomy. No invasive malignancies were identified on final pathology within the cecectomy cohort. LIMITATIONS: Single-institution data and retrospective design were limitations of this study. CONCLUSIONS: In tertiary centers, the majority of large cecal polyps are benign and can be addressed by using endoscopic mucosal resection. When involvement of the appendiceal orifice or ileocecal valve precludes endoscopic treatment, surgical resection is the standard of care. In the subset of cases not involving the ileocecal valve and without preoperative evidence of malignancy, partial cecectomy spares the ileocecal valve and can offer reduced postoperative morbidity compared with a formal right hemicolectomy.

BACKGROUND: Robotic approaches for colorectal surgery have been growing in popularity as experience with the new technology develops, but are frequently associated with longer operative time. It is unclear whether prolonged operative duration in robotic cases translates to increased morbidity. This study aims to compare the outcomes of non-emergent laparoscopic and robotic colon resections. METHODS: Patients undergoing non-emergent laparoscopic (LC) or robotic (RC) colon resections were identified in National Surgical Quality Improvement Project (2013-2015). Patients were matched 1:1 between cohorts using propensity score matching. To account for the prolonged operative time associated with robotic cases, operative times were stratified into approach-specific (LC or RC) tertiles (low, medium, and high) as covariates in the matching algorithm. RESULTS: RC increased significantly over time and had lower conversion rates (6.0% among RC versus 11.5% among LC, P < 0.001). RC cases were longer (226 min versus 178 min, P < 0.001). Unadjusted complication rates were higher in the LC cohort (17.5% versus 15.2%, P < 0.001). After propensity score matching, RC was not associated with a significant difference in postoperative morbidity (15.2% among RC versus 15.9% among LC, P = 0.434). The robotic approach was associated with a one-half day shorter length of stay (4.6 d versus 5.2 d, P < 0.001), but similar 30-day readmission rates (8.9% versus 8.3%, P = 0.368). CONCLUSIONS: After controlling for operative duration and patient covariates, RC was associated with similar rates of postoperative morbidity, but decreased conversion rates and shorter length of stay. Further studies examining costs are needed to evaluate whether these benefits offset the increased costs associated with robotic approaches.

PURPOSE: Anxiety and depression (A&D) are more common in inflammatory bowel disease (IBD) and in IBD patients who undergo proctocolectomy with ileal pouch-anal anastomosis (IPAA). Our aim was to test the hypothesis that chronic inflammatory conditions in IPAA are associated with increased incidence of A&D. METHODS: Retrospective cohort study at a single tertiary care referral center using a consented IBD and colon cancer natural history registry. Demographic and clinical factors, including surgical and psychiatric history, were abstracted. RESULTS: We compared A&D rate in three cohorts: (1) ulcerative proctocolitis with IPAA (UC) (n = 353), (2) Crohn's disease/indeterminate proctocolitis with IPAA (CDIC) (n = 49), and (3) familial adenomatous polyposis with IPAA (FAP) (n = 33). Forty-six CDIC patients (93.9%) demonstrated pouch-related inflammation, while 126 UC patients (35.7%) and 2 FAP patients (6.1%) developed pouchitis. CDIC had a higher rate of A&D co-diagnosis compared to UC and FAP (20.4 vs.12.7 vs.12.1% respectively; p < 0.05). UC patients with pouchitis also exhibited a higher rate of A&D than UC without pouchitis (19.8 vs.8.8%; p < 0.05). Multivariable analysis demonstrated that pre-operative corticosteroid use (OR = 4.46, CI = 1.34-14.87, p < 0.05), female gender (OR = 2.19, CI = 1.22-3.95, p < 0.01), tobacco use (OR = 2.92, CI = 1.57 = 5.41, p < 0.001), and pouch inflammation (OR = 2.37, CI = 1.28-4.39, p < 0.05) were each independently associated with A&D in these patients. CONCLUSIONS: Anxiety and depression were more common in patients experiencing inflammatory conditions of the pouch. UC without pouchitis and FAP patients demonstrated lower rates of A&D (that were comparable to the general population), implying that having an IPAA alone was not enough to increase risk for A&D. Factors independently associated with A&D in IPAA included an inflamed pouch, corticosteroid use, smoking, and female gender.
