Racial disparities in survival of early onset colon cancer (Age<50): A matched NCDB analysis.

BACKGROUND: Early-onset colon cancer (EOCC) has increasing incidence and disproportionately affects African-Americans. This analysis aims to compare EOCC survival among Black and White patients after matching relevant socio-demographic factors and stage. METHODS: The 2004-2017 NCDB database was queried for Black and White patients, age<50, who underwent colectomy for adenocarcinoma. A one-to-one match on race was performed based on sociodemographic factors and disease stage (I-IV). Five-year survival differences were analyzed with Cox proportional hazards models. RESULTS: 5322 Black-White matched pairs were analyzed. Compared to White patients, Black patients averaged more days to surgery (19 â€‹± â€‹68 vs 16 days â€‹± â€‹32, p â€‹< â€‹0.001) and to chemotherapy (63 â€‹± â€‹8 vs. 57 â€‹± â€‹39, p â€‹< â€‹0.001). Black stage III patients were 20% less likely to receive chemotherapy (OR 0.8, 95% CI 0.7-0.9, p â€‹= â€‹0.0006), and had a 17% increased rate of death (HR 1.17, 95% CI 1.0-1.3, p â€‹= â€‹0.01) after adjusting for sex, comorbidity score, tumor location and chemotherapy. CONCLUSIONS: Black patients with stage 3 EOCC are less likely to receive chemotherapy and have worse survival. Further evaluation is warranted to identify potential factors driving these observed.

Impact of Gender Inequity on Women Surgeons in the Professional Setting.

The concept of equity ensures that each individual is given the environment, treatment, and resources needed to reach an equal outcome to those around them. Equity is central to initiatives for advancing diversity and inclusion among physicians. This article will identify key barriers to equity that women surgeons face within the professional setting. More specifically, inadequate female representation, discrimination in the form of unconscious gender bias and microaggressions, and sexual harassment will be explored regarding their continued threats to gender equity, as well as constructive ways to mitigate these effects.

Assessing the Quality of Online Health Information and Trend Data for Colorectal Malignancies.

INTRODUCTION: Patients often refer to the internet to learn about different health conditions. This study aims to assess the landscape of online health information on malignant colorectal conditions, focusing on the popularity, quantity, and quality of internet resources pertaining to these conditions. This information can be used as a guide for surgeons to supplement patient information at the time of surgical evaluation and to help design optimal online health information. METHODS: The terms "colon cancer," "rectal cancer," "anal cancer," and "colorectal cancer" were searched using the Google search engine. The number of search results or "hits" obtained per search term was recorded and the first 50 websites for each search term were reviewed. Included websites did not have a password requirement, were in English, and were free. Quality assessments were performed using the DISCERN instrument, and mean DISCERN scores were compared using analysis of variance. The popularity of each search term was determined using Google Trends, which generates a relative search volume score. RESULTS: A total of 431 million hits were obtained for the term "colon cancer," 72.5 million for "rectal cancer," 244 million for "anal cancer," and 194 million for "colorectal cancer." Mean DISCERN scores for reviewed websites ranged between 39.7 and 40.6, and were thus within the "fair" category. There were no significant differences in mean DISCERN scores across search terms (P = 0.5). Colon cancer had the highest relative search volume score (61.8), followed by colorectal cancer (43.4/100), rectal cancer (42.5/100), and anal cancer (41.7/100). CONCLUSIONS: Although there is a large amount of online information on malignant colorectal conditions, the quality of the available information is inadequate. Clinician guidance to resources aimed at higher quality from guidance of the DISCERN tool may be of value for patient education.

Prospective Evaluation of a Tiered Opioid Prescribing Guideline for Inpatient Colorectal Operations.

OBJECTIVE: This study sought to prospectively validate an institutional prescribing guideline based on previously defined opioid consumption patterns following inpatient colorectal operations. BACKGROUND: In light of the opioid epidemic, reducing excess prescription quantities is key while still tailoring to patient needs. METHODS: This is a cohort study of elective colorectal operations (colectomies, proctectomies, and ostomy reversals) at a single tertiary care medical center. Opioid prescribing and consumption patterns [quantified as Equianalgesic 5 mg Oxycodone Pills (EOP)] were compared before and after adoption of a tiered opioid prescribing guideline. Tiers were divided based on opioid consumption in the 24 hours before discharge: Tier 1 (0 EOP), Tier 2 (0.1-3 EOP), and Tier 3 (>3 EOP). Our guideline recommended maximum prescriptions of 0 EOP for Tier 1, 12 EOP for Tier 2, and 30 EOP for Tier 3. Results: The study included 100 patients before and 101 after guideline adoption. Demographic and operative characteristics were similar between cohorts. Guideline adherence was 85%. Overall, there was a 41%reduction in mean prescription quantity and 53% reduction in excess pills per prescription. No change in opioid consumption or refill rates was observed. CONCLUSIONS: Adoption of a tiered opioid prescribing guideline significantly reduced opioid prescription quantity with no change in consumption or refill rates. Standardization of discharge prescriptions based on patient consumption in the 24 hours before discharge may be an important step toward minimizing excess prescribing.

Colonoscopy Needs for Implementation of a Colorectal Cancer Screening Program in Ukraine.

BACKGROUND: In Ukraine, there is no established colorectal cancer screening program. We aimed to project the number of screening colonoscopies needed for implementation of various CRC screening strategies in Ukraine. METHODS: We modified a previously developed Markov microsimulation model to reflect the natural history of adenoma and CRC progression among average-risk 50-74-year-olds. We simulated colonoscopies needed for the following screening strategies: no screening, fecal occult blood test yearly, FOBT yearly with flexible sigmoidoscopy every 5 years, FS every 5 years, fecal immunohistochemistry test (FIT) yearly, or colonoscopy every 10 years. Assuming 80% screening adherence, we estimated colonoscopies required at 1 and 5 years depending on the implementation rate. In one-way sensitivity analyses, we varied implementation rate, screening adherence, sensitivity, and specificity. RESULTS: Assuming an 80% screening adherence and complete implementation (100%), besides a no screening strategy, the fewest screening colonoscopies are needed with an FOBT program, requiring on average 6,600 and 26,800 colonoscopies per 100,000 persons at 1 and 5 years post-implementation, respectively. The most screening colonoscopies are required with a colonoscopy program, requiring on average 76,600 and 101,000 colonoscopies per 100,000 persons at 1 and 5 years post-implementation, respectively. In sensitivity analyses, the biggest driver of number of colonoscopies needed was screening adherence. CONCLUSIONS: The number of colonoscopies needed and therefore the potential strain on the healthcare system vary substantially by screening test. These findings can provide valuable information for stakeholders on equipment needs when implementing a national screening program in Ukraine.

Efficacy and satisfaction of asynchronous TeleHealth care compared to in-person visits following colorectal surgical resection.

BACKGROUND: The feasibility of remote visits following abdominal colorectal surgery has not been studied in relation to efficacy, patient satisfaction, and surgeon satisfaction. This study aims to assess reliability and satisfaction with a web-based questionnaire for post-operative visits following abdominal colorectal surgery. METHODS: This was a prospective single-arm cohort study at single-tertiary care center during admission for abdominal colorectal surgery. Using a web-based patient portal, patients completed a questionnaire 48 h prior to their scheduled in-person follow-up visits and submitted photographs of their incisions. Surgeons reviewed patient-entered data and responded within 24 h. Following the subsequent in-person visit, surgeons completed questionnaires to compare the accuracy of the web-based vs. in-person evaluations. Lastly, patients and surgeons completed separate satisfaction surveys after the in-person visits. RESULTS: A total of 33 patients were enrolled, of which 30 (90.9%) successfully completed the web questionnaire. Providers reported the online questionnaire to be concordant with the in-person visit in 90% of cases. Of the patients who completed the study, only half found the survey alone to be acceptable for follow-up. Patients spent significantly less time completing the online questionnaire (≤ 10 min) than in-person visits, including travel time (75 min, IQR 50-100). Only 12 patients (40%) uploaded photographs of their incisions. During in-person visits, management changes were employed in four patients (13.3%), of which 3 required treatment of superficial surgical site infections (10%). CONCLUSION: This asynchronous web-based visit format was acceptable to colorectal surgeons but was only embraced by half of patients, despite considerable time savings. While patients preferred in-person visits, there may be opportunities to expand TeleHealth acceptance that focus on patient selection and education. CLINICALTRIALS: gov: NCT05084131.

Promoting Female Leadership in Academic Surgery: Disrupting Systemic Gender Bias.

Gender bias is a pervasive issue in academic surgery and is characterized by familiar patterns previously described in the business world. In this article, the authors illuminate gender bias patterns in academic surgery identified in prior in-depth interviews with female surgical department chairs across the United States. The 4 main gender bias patterns drawn from the business world and illuminated with data from the interviews are (1) prove-it-again, (2) tightrope or double-blind dilemma, (3) maternity wall or benevolent bias, and (4) tug-of-war. The authors propose steps to disrupt systemic gender bias issues recognized in the academic surgery community. The proposed steps are informed by guidance from surgical diversity task forces, by existing literature, and by the authors' own experiences in the field. The steps are divided into 3 main categories: education, structured mentorship, and transparency. The proposed changes include improving training and recognition of unconscious bias, establishing level-appropriate and deliberate mentorship across all stages of training and practice, standardizing promotional requirements, and eliminating outdated standards that contribute to the gender pay gap. Although this article addresses gender bias in academic surgery, the proposed steps toward change can promote equity across the surgical community as a whole and extend to other underrepresented groups in the field.

S184: preoperative sarcopenia is associated with worse short-term outcomes following transanal total mesorectal excision (TaTME) for rectal cancer.

INTRODUCTION: Malnutrition and deconditioning impact postoperative morbidity and mortality. Computed tomography (CT) body composition variables are used as markers of nutritional status and sarcopenia. The objective of this study is to evaluate the impact of sarcopenia, using CT variables, on postoperative outcomes following transanal total mesorectal excision (TaTME) for rectal cancer. METHODS: This was an institutional retrospective cohort analysis of consecutive rectal cancer patients who underwent TaTME between April 2014 and May 2020. Psoas muscle index (PMI) was calculated from diagnostic CT scans. Based on previous studies, patients in the lowest PMI tertile by gender were considered sarcopenic. Fisher's exact and Mann-Whitney U test were used to compare categorical and continuous variables, respectively. Readmission rates and postoperative complications were compared between groups. Backward stepwise logistic regression was used to determine the association between sarcopenia and 30-day postoperative complications. RESULTS: 85 patients were analyzed, of which 63% were male, with a median age of 59 (IQR: 51-65), and median BMI of 28 (IQR: 24-32). Of the entire cohort, 34% (n = 29) were sarcopenic (median PMI 5.39 IQR: 4.49-6.71). No significant difference in baseline characteristics between sarcopenic and nonsarcopenic patients were observed. 55% of sarcopenic patients experienced a complication within 30 days compared to 24% of nonsarcopenic patients (p = 0.01). 41% of sarcopenic patients required hospital readmission within 30 days compared to 17% of their nonsarcopenic counterparts (p = 0.014). Sarcopenic patients also experienced significantly higher rates of post-operative small bowel obstruction (10% vs. 0%, p = 0.04). Multivariable analyses identified that sarcopenic patients have a fourfold increase in odds of experiencing a 30-day postoperative complication (OR: 4.44, 95%CI: 1.6-12.4, p < 0.05) after adjusting for gender. CONCLUSION: Preoperative sarcopenia is associated with increased 30-day postoperative complications following TaTME for rectal cancer. Postoperative complications can have serious oncologic implications by delaying adjuvant chemotherapy. Therefore, preoperative recognition of sarcopenia prior to undergoing TaTME for rectal cancer may provide an opportunity for early intervention with prehabilitation programs.

Oncologic Outcomes After Transanal Total Mesorectal Excision for Rectal Cancer.

BACKGROUND: Recent series have raised concerns about the oncologic outcomes of transanal total mesorectal excision for mid and low rectal cancer. There is a paucity of large data sets from the United States to contribute to the ongoing international discourse. OBJECTIVE: This study aimed to investigate the rate of local recurrence and other oncologic outcomes in patients undergoing transanal total mesorectal excision for rectal adenocarcinoma. DESIGN: This study is a retrospective review of patients undergoing transanal total mesorectal excision for primary rectal cancer from January 2014 to December 2019. SETTINGS: This study was conducted at a single academic tertiary care medical center in the United States. PATIENTS: Consecutive patients aged ≥18 years undergoing surgical resection for primary rectal cancer were selected. INTERVENTION: The transanal total mesorectal excision procedures were performed utilizing a 2-team approach. MAIN OUTCOME MEASURES: Primary outcomes were pathologic quality, local and distant recurrence, treatment-related complications, and overall- and cancer-specific survival. RESULTS: Seventy-nine consecutive patients were included. The median age was 58 years (interquartile range, 50-64), and median BMI was 28 kg/m2 (interquartile range, 24.6-32.4). The mesorectum was complete in 69 patients (87.3%), nearly complete in 9 (11.4%), and incomplete in 1 (1.3%). There was circumferential resection margin involvement (<1 mm) in 4 patients (5.1%), and no patients had a positive distal margin (<1 mm) or intraoperative rectal perforation. Composite optimal pathology was achieved in 94.9% of specimens. Median follow-up was 29 months (range, 6-68). There were no local recurrences. Distant metastases were found in 10 (13.5%) patients and diagnosed after a median of 14 months (range, 0.6-53). Disease-free survival was 91.2% at 2 years, and overall survival was 94.7% at 2 years. LIMITATIONS: Retrospective design, a single center, and relatively short follow-up period were limitations of this study. CONCLUSION: The oncologic outcomes of this cohort support the use of transanal total mesorectal excision in the surgical management of mid to low rectal cancer at centers with appropriate expertise.

Use of medical chaperones by colon and rectal surgeons in outpatient practice.

BACKGROUND: The purpose of this study is to determine the frequency and motivations for medical chaperone use during anorectal exams by colon and rectal surgeons in the outpatient setting. STUDY DESIGN: This cross-sectional study examined factors impacting chaperone use via an anonymous online survey distributed via the American Society of Colon and Rectal Surgeons email list. Routine chaperone use was defined as ≥ 90%. RESULTS: Of 1,380 emailed board-certified colon and rectal surgeons, 402 (29.1%) completed the survey in November 2019. Median years in practice was 14, and 72.3% were male. Overall, 65.2% reported routine use of chaperones during anorectal exams. Over half (56.3%) felt chaperones should be mandatory and were more likely to report routine use than those who did not (85.7 vs. 39.1%; p < 0.001). Only 23.7% reported that their institutions had formal chaperone policies. The most common reason for use was medicolegal (91.8%), and the most common barrier was chaperone availability (56.7%). When chaperones were used, 42% did not document use in the medical record. On multivariable analysis, increased odds of routine chaperone use were independently associated with: being ≤ 10 years in practice, routine chaperone use during fellowship, and chaperones being routinely available. CONCLUSION: Half of surgeons felt that chaperones should be mandatory, suggesting lack of consensus among the cohort. Despite expressing legal concerns, one-third did not use chaperones and nearly half who used chaperones did not document their use. Efforts to improve chaperone availability, documentation of chaperone use, and knowledge of policies are necessary.

Development of a Practice Guideline for Discharge Opioid Prescribing After Major Colorectal Surgery.

BACKGROUND: Better alignment of opioid prescription quantities with patient need could help reduce excessive prescribing. OBJECTIVE: The study sought to develop an institutional prescribing guideline based on defined opioid consumption patterns after inpatient colorectal operations. DESIGN: This was a retrospective cohort study. SETTINGS: The study was conducted at a single tertiary care center. PATIENTS: Patients who underwent elective major colorectal procedures between July 2018 and January 2019 were included. MAIN OUTCOME MEASURES: The study measured prescription and consumption quantities measured as equianalgesic oxycodone 5-mg pills. RESULTS: Patients were categorized into 3 groups based on consumption in the 24-hour period before discharge: tier 1 consumed 0 equianalgesic oxycodone 5-mg pills (n = 53), tier 2 consumed 0.1 to 3.0 equianalgesic oxycodone 5-mg pills (n = 25), and tier 3 consumed >3.0 equianalgesic oxycodone 5-mg pills (n = 22). Average prescription quantity was 17.5 ± 10.5 equianalgesic oxycodone 5-mg pills (range, 0-78). Patients consumed a mean of 6.7 ± 10.9 equianalgesic oxycodone 5-mg pills after discharge and had 10.8 ± 10.2 equianalgesic oxycodone 5-mg pill excess, whereas 51% of patients consumed no pills. Opioid consumption was significantly different between each tier (p < 0.001). A prescribing guideline was developed to satisfy the majority of patients: 0 equianalgesic oxycodone 5-mg pills if tier 1, 12 pills if tier 2, and 30 pills if tier 3. Tiered guideline adoption could reduce prescribed pills by 45% and excess pills per prescription by 73%. Patient history of IBD was independently associated with increased odds of exceeding the guideline (adjusted OR = 7.2 (95% CI, 1.6-32.6)). LIMITATIONS: The study was limited by its single-center, retrospective design and that outpatient opioid consumption was self-reported. CONCLUSIONS: Following hospital discharge after major colorectal surgery, more than half of patients consumed no opioid pills, and 62% of prescribed opioids were in excess. Outpatient opioid consumption was highly associated with inpatient opioid use in the 24 hours before discharge. Prospective validation of this prescribing guideline is needed, but adoption could reduce excessive prescribing. See Video Abstract at http://links.lww.com/DCR/B575. DESARROLLO DE UNA GUA PRCTICA PARA LA PRESCRIPCIN DE OPIOIDES AL EGRESO DESPUS DE UNA CIRUGA COLORRECTAL MAYOR: ANTECEDENTES:Una mejor alineación de las cantidades de prescripción de opioides con las necesidades del paciente podría ayudar a reducir la prescripción excesiva.OBJETIVO:El estudio buscó desarrollar una guía institucional de prescripción basada en patrones definidos de consumo de opioides luego de cirugías colorrectales hospitalarias.DISEÑO:Estudio de cohorte retrospectivo.ENTORNO CLÍNICO:El estudio se llevó a cabo en un solo centro de atención terciaria.PACIENTES:Pacientes que se sometieron a procedimientos colorrectales mayores electivos entre julio de 2018 y enero de 2019.PRINCIPALES MEDIDAS DE RESULTADO:El estudio midió las cantidades de prescripción y consumo medidas como píldoras de 5 mg de oxicodona equianalgésica (EOP).RESULTADOS:Los pacientes se clasificaron en tres grupos según el consumo en el período de 24 horas antes del egreso: el nivel 1 consumió 0 EOP (n = 53), el nivel 2 consumió 0,1-3 EOP (n = 25) y el nivel 3 consumió más de 3 EOP (n = 22). La cantidad promedio de prescripción fue 17,5 (± 10,5) EOP (rango: 0-78). Los pacientes consumieron una media de 6,7 (± 10,9) EOP posterior al egreso y tuvieron un exceso de 10,8 (± 10,2) EOP, mientras que el 51% de los pacientes no consumieron píldoras. El consumo de opioides fue significativamente diferente entre cada nivel (p <0,001). Se desarrolló una guía de prescripción para satisfacer a la mayoría de los pacientes: 0 EOP del nivel 1, 12 EOP del nivel 2 y 30 EOP del nivel 3. La adquisición de una guía escalonada podría reducir las píldoras recetadas en un 45% y el exceso de píldoras por receta en un 73%. El historial del paciente de enfermedad inflamatoria intestinal se asoció de forma independiente con un aumento de las probabilidades de superar la guía (ORa 7,2; IC del 95%: 1,6-32,6).LIMITACIONES:El estudio estuvo limitado por su diseño retrospectivo de un solo centro y por el consumo de opioides del paciente ambulatorio el cual fue autoinformado.CONCLUSIONES:Tras el egreso hospitalario de una cirugía colorrectal mayor, más de la mitad de los pacientes no consumieron pastillas opioides y el 62% de los opioides prescritos estaban en exceso. El consumo de opioides como paciente ambulatorio estuvo altamente asociado con el uso de opioides como paciente hospitalizado en las 24 horas previas al egreso. Se necesita una validación prospectiva de esta guía de prescripción, pero la adopción podría reducir la prescripción excesiva. Consulte Video Resumen en http://links.lww.com/DCR/B575.

Total Transperineal Laparoscopic Proctectomy for the Treatment of Crohn's Proctitis.

INTRODUCTION: Completion proctectomy is traditionally performed using a combination of abdominal and perineal approaches. Access to and exposure of the pelvis through the abdominal cavity can be limited in patients with prior surgery or inflammatory conditions. We describe a novel technique for a total transperineal approach for proctectomy for Crohn's proctitis, avoiding technical challenges, risks, and recovery associated with abdominal surgery. TECHNIQUE: We utilized the skills and expertise acquired from our experience with transanal total mesorectal excision to perform a total transperineal laparoscopic proctectomy in a male patient with medically refractory proctitis. He previously underwent an anterior resection, drainage of a chronic presacral abscess, omental pedicle flap transposition to the pelvis, and end colostomy for severe Crohn's colitis. The total transperineal laparoscopic proctectomy approach avoids the need for abdominal access, including the risks associated with abdominal entry, adhesiolysis, pelvic access and visualization, and wound-related issues. Following an initial intersphincteric perineal dissection, the GelPOINT Path minimal access platform is utilized to perform a total transperineal proctectomy. RESULTS: The patient recovered uneventfully and was discharged to home 2 days after surgery. At 1-month postoperative follow-up, the patient is recovering well with complete healing of the perineal wound. CONCLUSION: We demonstrate the feasibility, safety, and technical steps of a minimally invasive completion proctectomy for fistulizing Crohn's proctitis by using a total transperineal approach. This approach allowed us to utilize direct, inline, high-definition visualization to access and safely operate in the distal aspects of a narrow, scarred, and fibrotic pelvis while avoiding the need for any abdominal access. Advanced experience with redo pelvic and minimally invasive transanal surgery is critical. See Video at http://links.lww.com/DCR/B664.
