RESUMEN
BACKGROUND: The transanal abdominal transanal radical proctosigmoidectomy was developed in 1984 as a sphincter preservation surgery in patients with low rectal cancers after preoperative radiation therapy. While serving as a catalyst for disruptive sphincter preservation surgery, it continues to be used and evolve. With the controversy over safety and local recurrence in other sphincter-preserving surgery, review of transanal abdominal transanal radical proctosigmoidectomy long-term oncologic outcomes is warranted. OBJECTIVE: To assess local recurrence and survival after transanal abdominal transanal radical proctosigmoidectomy after neoadjuvant chemoradiation therapy. DESIGN: Retrospective cohort study of a prospectively maintained database. SETTINGS: Tertiary rectal cancer referral center. PATIENTS: Patients with low adenocarcinoma (≤5 cm anorectal ring) receiving neoadjuvant chemoradiation therapy and then transanal abdominal transanal radical proctosigmoidectomy for curative resection between 1998 and 2021. MAIN OUTCOME MEASURES: Local recurrence rates and overall survival rates. RESULTS: Of 255 included patients, 67.8% were men (n = 173); the mean age was 58.7 years (SD 11.5) and the mean BMI was 27.1 (SD 5.4), with 50.2% (n = 128) having ASA class II and 49.8% (n = 127) having ASA class III/IV. The mean tumor size was 4.8 cm (SD 1.9), the majority of patients had clinical T3 disease (81.8%; n = 184), and 52.1% had nodal disease (n = 100). The median radiation dose was 5400 cGy, with 73.7% (n = 149) achieving good response and 90.2% (n = 230) receiving minimally invasive surgery. The complete total mesorectal excision rate was 94.3%, and 100% of patients (n = 255) had negative distal margins. The mean number of examined lymph nodes were 13.9 (SD 10.7). After a median follow-up of 55.4 months, 5.1% of patients (n = 13) developed local recurrence at a median time of 29.6 months. The 5-year overall survival was 84.1% (95% CI, 78.8-89.4). LIMITATIONS: Retrospective review with risk of bias and lack of generalizability. CONCLUSIONS: In this longitudinal study, the transanal abdominal transanal radical proctosigmoidectomy demonstrated excellent long-term locoregional control and survival in very low rectal cancers. The superior transanal abdominal transanal radical proctosigmoidectomy outcomes are durable over time, warranting expansion of the sphincter-preserving surgery technique. See Video Abstract .

RESUMEN
BACKGROUND: Robotics has increased rates of minimally invasive surgery, with distinct advantages over open surgery. However, current commercially available robotic platforms have device and system issues that limit robotic-assisted surgery expansion. OBJECTIVE: To demonstrate the safety and efficacy of a novel miniaturized robotic-assisted surgery device in colectomy. DESIGN: Prospective, Investigational Device Exemption clinical study following the idea, development, exploration, assessment, and long-term follow-up framework (stage 2b, exploration). SETTINGS: Three centers with high-volume robotic colorectal cases and surgeons. PATIENTS: Patients scheduled for a right or left colectomy for benign or malignant disease. INTERVENTION: Colectomy with the novel miniaturized robotic-assisted surgery device. MAIN OUTCOME MEASURES: For safety, intraoperative and device-related adverse events and 30-day morbidity. For efficacy, successful completion of predefined procedural steps without conversion. RESULTS: Thirty patients (13 women, 17 men) were analyzed. The mean age was 59.4 (SD 13.4) years. Seventy percent of patients (n = 21) were overweight/obese and 53.3% of patients (n = 16) had prior abdominal surgery. Forty percent of patients had malignant and 60% had benign disease. Cases were 15 right and 15 left colectomies. Overall operative time was a median of 146 (range, 80-309) minutes; console time was 70 (range, 34-174) minutes. There were no conversions to open surgery and no intraoperative or device-related adverse events. In 100% of patients (n = 30), the primary dissection was completed, and hemostasis was maintained with the novel miniaturized robotic-assisted surgery device. The morbidity rate was 26.7% minor and 3.3% major. The median length of stay was 2 days. There were no mortalities. LIMITATIONS: Single-arm study, short-term follow-up. CONCLUSIONS: This first clinical study of a novel miniaturized robotic-assisted surgery device along the IDEAL framework demonstrated that it was safe and effective. Given this success, further assessment and long-term follow-up of the miniaturized robotic-assisted surgery device are planned for comparative clinical and economic effectiveness in colorectal surgery.

BACKGROUND: Single-incision laparoscopic surgery (SILS) may offer improved cosmesis, reduced postoperative pain and faster recovery than conventional platforms, but widespread implementation was limited by technical demands. A single-port robotic platform was recently introduced, with components that further enhance SILS benefits without the technical challenges. No study to date has compared the two platforms to validate benefits. Our goal was to compare outcomes of SP robotics and SILS in colorectal cancer (CRC). METHODS: A prospective cancer registry was reviewed for CRC patients undergoing curative resection through a SILS or SP robotic approach from 2010 to 2022. Patient and cancer demographics, intraoperative, and postoperative outcomes were compared in a 1:1 propensity score-matched cohort, adjusting for baseline characteristics. The main outcome measures were complications, operative time, and oncologic quality measures. RESULTS: Matching resulted 50 SP robotic and 50 SILS patients. Cohorts were well matched in all demographics, but SP robotic rectal cancer cases were significantly closer to the anorectal ring than SILS (1.8 cm vs. 3.4 cm, p = 0.018). SP robotic and SILS platforms had similar operative times. Intraoperative conversions was comparable, but more SILS cases required additional ports to be placed (p = 0.040). The intraoperative complications rate, complete total mesorectal excision rates, and lymph node yield were not statistically significantly different. There were no positive margins in either group. Postoperatively, groups had analogous day of return of bowel function, comparable morbidity, and discharge destination. There was no mortality in either group. The length of stay was significantly shorter with SP robotics than SILS (mean 4.135 vs. 5.282 days, median 4 (2-8) vs. 5 (2-14) days; p = 0.045). CONCLUSIONS: Single-port robotics provided high quality oncologic surgery, adding the technical benefits of robotics to clinical and cosmetic benefits of single-port surgery. There were comparable operative time, complication rates, and oncologic outcomes in CRC cases, with shorter hospital stays with SP robotics. This early data is encouraging for expansion SP robotic technology.

INTRODUCTION: The growth of surgeon burnout is of significant concern. As we work to reimagine the practice of surgery, an accurate understanding of the extent of surgeon burnout is essential. Our goal was to define the current prevalence of burnout and quality of life (QOL) among SAGES surgeons. METHODOLOGY: An electronic survey was administered to SAGES members to establish a current baseline for QOL, burnout, depression, and career satisfaction. To assess outcomes, we utilized the validated Maslach Burnout Inventory for Medical Personnel, the Medical Outcomes Study Short Form, and the Primary Care Evaluation of Mental Disorders. All scoring followed validated norm-based methods. RESULTS: Of 4194 active members, 604 responded (14.40%). 69% met burnout threshold, with high levels of emotional exhaustion and depersonalization, and low personal accomplishment. 81% reported "being at the end of their rope", 74% felt emotionally drained, and 65% felt used up daily. Nearly all maintained caring about what happened to their patients (96%), easily understanding how their patients feel (84.3%) and being capable of dealing effectively with their patient's problems (87.6%). However, respondents never, rarely, or occasionally felt energetic (77.5%) or experienced a sense of professional accomplishment (57.8%). The overall QOL score was 69/100, with lower Mental than Physical scores (62.69 (SD 10.20) vs.77.27 (SD 22.24)). More than half of respondents met depression criteria. While 77% supported they would become a physician again, less than half would choose surgery again or recommend surgery to their children. Furthermore, less than a third felt work allowed sufficient time for their personal lives. CONCLUSIONS: Participating SAGES surgeons reported alarmingly high rates of burnout and depression. Despite experiencing emotional exhaustion and depersonalization, they maintained a strong commitment to patient care. These findings likely reflect the broader state of surgeons, underscoring the urgent need for action to address this critical issue.
RESUMEN
BACKGROUND: Transanal surgery facilitates organ preservation in select patients with benign and early malignant rectal lesions to avoid the functional consequences of radical surgery. The transanal endoscopic microsurgery (TEM) platform created a standard for local excision with lower margin positivity and recurrence rates than traditional transanal excision. The single-port robot (SP r) presents a promising alternative transanal platform. The goal of this study was to compare perioperative and pathologic outcomes of TEM and SP r for excision of rectal lesions. METHODS: A review of consecutive patients who underwent local excision of rectal lesions at a tertiary referral center from 1/2001 to 5/2022 was performed. Cases were stratified into TEM or SP rTAMIS in a 1:1 propensity score-matched cohort, adjusting for all baseline characteristics. Clinical, tumor-specific, and perioperative outcomes were compared using χ2, and Mann-Whitney U-tests. The main outcomes were oncologic quality measures, complications, and operative time. RESULTS: Matching resulted 50 patients in each cohort. Groups had similar age, gender, body mass index, comorbidity, diagnosis, lesion characteristics, and neoadjuvant chemoradiation rates. There were no intraoperative complications in either cohort. Three SP rTAMIS cases were converted intraoperatively; there were no conversions in TEM. SP rTAMIS had significantly shorter operative times than TEM (mean 104 vs. 245, p = 0.027). The rates of positive distal margins (2% TEM, 0% SP rTAMIS) and piecemeal resection (4% TEM, 0% SP rTAMIS) were similar. SP rTAMIS had significantly lower postoperative morbidity rates than TEM (9% vs. 20%, p = 0.031). There was no mortality in either cohort. CONCLUSIONS: SP robotics provided high-quality outcomes similar to TEM for local excision of rectal lesions. SP robotics had faster operative time with comparable clinical and oncologic outcomes to TEM. These early data are promising for expanding use of SP robotic platforms.

INTRODUCTION: Endoscopy is an essential skill for all surgeons. However, endoscopic competency, training, and practice may vary widely among them. The EAES Flexible Endoscopy Subcommittee is working towards a standardized set of fundamental endoscopic knowledge and skills. To best advise on current practice patterns of flexible endoscopy among surgeons worldwide, a snapshot audit was conducted on the training, use, and limitations of flexible endoscopy in practice. METHODS: An online survey was distributed via email distribution and social media platforms for EAES, SAGES, and WebSurg members. Respondent demographics, training, and practice patterns were assessed. The main outcome measure was the annual endoscopic volume. Multivariate regression and machine learning models analyzed relationships between outcomes and independent variables of age, geographic region, laparoscopic surgery practice, and surgical specialization. RESULTS: A total of 1486 surgeons from 195 countries completed the survey. Respondents were mainly general (n = 894/1486, 60.2%), colorectal (n = 189/1486, 12.7%), bariatric (n = 117/1486, 7.9%), upper gastrointestinal (GI)/foregut (n = 108, 7.3%), hepatobiliopancreatic/HPB (n = 59/1486, 4%), and endocrine surgeons (n = 11/1486, 0.7%) in active practice. Eighty-two percent (n = 1,204) mentioned having used endoscopy in their practice, and 64.7% (n = 961/1486) received formal flexible endoscopy training. Of those performing endoscopy annually, 64.2% (n = 660/1486) performed between 0 and 20 endoscopies, 15.2% (n = 156/1486) performed between 20 and 50 endoscopies, 10.1% (n = 104/1486) performed between 50 and 100 endoscopies, and 10.5% (n = 108/1486) performed over 100 endoscopies. From the regression analysis, there was no statistical correlation between the annual endoscopy volume and age, geographic region, laparoscopic surgery practice, or surgical specialization. Performing advanced endoscopy was directly related to the bariatric subspecialty and to performing over 50% of cases in a minimally invasive fashion. CONCLUSIONS: This international snapshot audit revealed significant heterogeneity in endoscopic practices among surgeons worldwide. There was a nonindependent relationship between endoscopy volumes and other variables tested. Barriers to practicing and receiving endoscopy training were common among respondents. The EAES Flexible Endoscopy Subcommittee will consider such results when developing an equitable and effective standardized flexible endoscopy curriculum.
RESUMEN
BACKGROUND: As the population ages, more older adults are presenting for surgery. Age-related declines in physiological reserve and functional capacity can result in frailty and poor outcomes after surgery. Hence, optimizing perioperative care in older patients is imperative. Enhanced Recovery After Surgery (ERAS) pathways and Minimally Invasive Surgery (MIS) may influence surgical outcomes, but current use and impact on older adults patients is unknown. The aim of this study was to provide evidence-based recommendations on perioperative care of older adults undergoing major abdominal surgery. METHODS: Expert consensus determined working definitions for key terms and metrics related to perioperative care. A systematic literature review and meta-analysis was performed using the PubMed, Embase, Cochrane Library, and Clinicaltrials.gov databases for 24 pre-defined key questions in the topic areas of prehabilitation, MIS, and ERAS in major abdominal surgery (colorectal, upper gastrointestinal (UGI), Hernia, and hepatopancreatic biliary (HPB)) to generate evidence-based recommendations following the GRADE methodology. RESULT: Older adults were defined as 65 years and older. Over 20,000 articles were initially retrieved from search parameters. Evidence synthesis was performed across the three topic areas from 172 studies, with meta-analyses conducted for MIS and ERAS topics. The use of MIS and ERAS was recommended for older adult patients particularly when undergoing colorectal surgery. Expert opinion recommended prehabilitation, cessation of smoking and alcohol, and correction of anemia in all colorectal, UGI, Hernia, and HPB procedures in older adults. All recommendations were conditional, with low to very low certainty of evidence, with the exception of ERAS program in colorectal surgery. CONCLUSIONS: MIS and ERAS are recommended in older adults undergoing major abdominal surgery, with evidence supporting use in colorectal surgery. Though expert opinion supported prehabilitation, there is insufficient evidence supporting use. This work has identified evidence gaps for further studies to optimize older adults undergoing major abdominal surgery.

BACKGROUND: Standard management of stage III colon cancer includes surgical resection and adjuvant chemotherapy. Despite improved overall survival with adjuvant chemotherapy in stage III colon cancer, it is reportedly underused in older adults. To date, no contemporary national analysis of adjuvant chemotherapy use and its impact on older adults with stage III colon cancer exists. OBJECTIVE: This study aimed to assess the current use of adjuvant chemotherapy in older adults with stage III colon cancer and determine factors associated with noncompliance. DESIGN: Retrospective cohort study. SETTINGS: Conducted using the National Cancer Database. PATIENTS: This study included patients aged 65 years and older undergoing curative resection for stage III colon adenocarcinomas, 2010-2017. MAIN OUTCOME MEASURES: Adjuvant chemotherapy use, factors associated with adjuvant chemotherapy use, and overall survival with and without adjuvant chemotherapy in older adults with pathologic stage III disease. RESULTS: Of 64,608 patients included, 64.3% received adjuvant chemotherapy. Adjuvant chemotherapy was significantly independently associated with improved 1-, 3-, and 5-year overall survival vs no adjuvant chemotherapy (92.8%, 75.3%, 62.4% vs 70.8%, 46.6%, 32.7%; HR 0.475; 95% CI, 0.459-0.492; p <0.001). Compared with the no adjuvant chemotherapy cohort, patients who received adjuvant chemotherapy were younger, female, and less comorbid ( p < 0.001). Factors associated with adjuvant chemotherapy noncompliance included advancing age, lower annual income, open approach, longer length of stay, pathologic stage IIIA, and fewer than 12 lymph nodes. LIMITATIONS: Administrative data source with inherent risks of bias, coding errors, and limitations in the fields available for analysis. CONCLUSIONS: Adjuvant chemotherapy significantly improved overall survival but was only used in 64.3% of older adults with stage III colon cancer. Adjuvant chemotherapy noncompliance was seen in the most vulnerable and highest-risk patients, including those with greater comorbidity, lower income, and patients who received open surgery.

A pesar de la mejora de la supervivencia general con la quimioterapia adyuvante en el cáncer de colon en estadio III, se reporta que se utiliza poco en los adultos mayores. Hasta la fecha, no existe ningún análisis nacional actual, sobre el uso de quimioterapia adyuvante y su impacto en adultos mayores con cáncer de colon en etapa III.OBJETIVO: Evaluar el uso actual de quimioterapia adyuvante en adultos mayores con cáncer de colon en estadio III y determinar los factores asociados con el incumplimiento.DISEÑO: Estudio de cohorte retrospectivo.AJUSTES: Realizado y utilizando la Base de Datos Nacional de Cáncer.PACIENTES: Pacientes de 65 años o más sometidos a resección curativa por adenocarcinomas de colon en estadio III de 2010-2017.PRINCIPALES MEDIDAS DE RESULTADO: Uso de quimioterapia adyuvante, factores asociados con el uso de quimioterapia adyuvante y supervivencia general con y sin quimioterapia adyuvante en adultos mayores con enfermedad en estadio patológico III.RESULTADOS: De 64.608 pacientes incluidos, el 64,3% recibió quimioterapia adyuvante. La quimioterapia adyuvante se asoció de forma significativa e independiente con una mejor supervivencia general a 1, 3 y 5 años frente a ninguna quimioterapia adyuvante (92,8 %, 75,3 %, 62,4 % frente a 70,8 %, 46,6 %, 32,7 %; respectivamente, HR 0,475, 95 % IC 0,459-0,492, p < 0,001). En comparación con la cohorte sin quimioterapia adyuvante, los pacientes que recibieron quimioterapia adyuvante eran más jóvenes, mujeres y con menos comorbilidad. (p < 0,001). Los factores asociados con el incumplimiento de la quimioterapia adyuvante incluyeron edad avanzada (OR 0,857, IC del 95 % 0,854-0,861), ingresos anuales más bajos (OR 0,891, IC del 95 % 0,844-0,940), abordaje abierto (0,730, IC del 95 % 0,633-0,842), mayor duración de la estancia (OR 0,949, IC 95% 0,949-0,954) y estadio patológico IIIA (0,547, IC 95% 0,458-0,652) y <12.LIMITACIONES: Fuente de datos administrativos con riesgos inherentes de sesgo, errores de codificación y limitaciones en los campos disponibles para el análisis.CONCLUSIONES: La quimioterapia adyuvante mejoró significativamente la supervivencia general, pero solo se utilizó en el 64,3 % de los adultos mayores con cáncer de colon en estadio III. El incumplimiento de la quimioterapia adyuvante se observó en los pacientes más vulnerables y de mayor riesgo, incluidos aquellos con mayor comorbilidad, menores ingresos y pacientes que recibieron cirugía abierta.

AIM: Slow laparoscopy adoption accelerated the uptake of robotic surgery. However, the current robotic platforms have limitations in transanal applications and multiple port sites. The da Vinci single-port (SP) robot is currently used on trial for colorectal surgery, and broad assessment of outcomes is needed. We aimed to report findings of a phase II clinical trial of SP robotic colorectal surgery. METHODS: A sequentially reported prospective case series was performed on patients using SP robotics at a tertiary referral centre from 1 October 2018 to 31 August 2021. Cases were stratified into abdominal and transanal cohorts. Demographics, intra-operative variables and 30-day postoperative outcomes were evaluated. Univariate analysis was performed, with statistical process control for the docking process. Main outcomes were conversion rates, morbidity, mortality and point of standardization of docking. RESULTS: In all, 133 patients were included: 93 (69.92%) abdominal and 40 (30.08%) transanal. The main diagnosis was rectal cancer (n = 59) and the procedure performed a robotic transanal abdominal transanal radical proctosigmoidectomy (n = 30). There were no conversions to open surgery. Two abdominal (2.15%) and three transanal cases (7.50%) were converted to laparoscopy. All colorectal adenocarcinomas had negative margins, proper lymph node harvest and complete mesorectal excision, as appropriate. Docking became a standardized process at cases 34 (abdominal) and 23 (anorectal). After surgery, bowel function returned on mean day 2 (abdominal) and 1 (transanal). The morbidity rate was 15.05% (abdominal) and 27.50% (transanal). There were two major morbidities in each cohort. Overall, there were three (2.65%) readmissions, one reoperation and no mortality. CONCLUSIONS: Single-port robotics is feasible for all types of colorectal procedures, with good clinical and oncological outcomes. With this development in colorectal surgery, further studies can develop best practices with this novel technology.

BACKGROUND: From clinical experience, many patients undergoing robotic assisted surgery (RAS) have a poor understanding of the technology. To ensure informed consent and appropriate expectations, a needs assessment for patient-centered education and outcome metrics in RAS is warranted. Our goal was to perform an assessment of patient understanding, comfort with robotic technology, and ability to obtain critical information from their surgeon when undergoing RAS. METHODS: Twenty patients planned for RAS by three surgeons were asked to complete a six-item Likert agreement scale survey prior to signing informed consent. The study coordinator administered surveys, while the surgeon left the room. Indicator statements were crafted to reduce bias and two-way evaluated for consistency. The surgeons were additionally asked their perception of each patient's understanding and comfort with RAS. Frequency statistics and tendencies were analyzed. RESULTS: Surgeons strongly agreed all patients appropriately understood how RAS functioned and would ask more questions before signing consent, if needed. Patients were predominately not familiar with RAS and felt surgeons did not explain how RAS worked. There was wide variability on if patients understood how RAS worked for their treatment. Overall, patients were not completely comfortable with RAS for their care, did not understand the risks of RAS compared to other approaches, and did not feel their surgeon understood what they needed to know to make informed decisions. CONCLUSIONS: This needs assessment demonstrated critical gaps in patient knowledge about RAS, surgeon communication skills, and the ability of surgeons to know what was important from the patient perspective. The development of RAS patient-centered education and outcome metrics could help address these gaps.

BACKGROUND: Single snapshot imaging of optical properties (SSOP) is a relatively new non-invasive, real-time, contrast-free optical imaging technology, which allows for the real-time quantitative assessment of physiological properties, including tissue oxygenation (StO2). This study evaluates the accuracy of multispectral SSOP in quantifying bowel ischaemia in a preclinical experimental model. METHODS: In six pigs, an ischaemic bowel segment was created by dividing the arcade branches. Five regions of interest (ROIs) were identified on the bowel loop, as follows: ROI 1: central ischaemic; ROI 2: left marginal; ROI 3: left vascularised; ROI 4: right marginal; and ROI 5: right vascularised. The Trident imaging system, specifically developed for real-time tissue oxygenation imaging using SSOP, was used to image before (T0) and after ischaemia induction. Capillary and systemic lactates were measured at each time point (T0, T15, T30, T45, T60), as well as StO2 values acquired by means of SSOP (SSOP-StO2). RESULTS: The mean value of SSOP-StO2 in ROI 1 was 30.08 ± 6.963 and was significantly lower when compared to marginal ROIs (ROI 2 + ROI 4: 45.67 ± 10.02 p = < 0.0001), and to vascularised ROIs (ROI 3 + ROI 5: 48.08 ± 7.083 p = < 0.0001). SSOP-StO2 was significantly correlated with normalised lactates r = - 0.5892 p < 0.0001 and with histology r =- 0.6251 p = 0.0002. CONCLUSION: Multispectral SSOP allows for a contrast-free accurate assessment of small bowel perfusion identifying physiological tissue oxygenation as confirmed with perfusion biomarkers.

PURPOSE: Social media (SoMe) is increasingly important in surgical education and may be necessary in the current learning environment. Whilst expanding in use and applications, few studies detail the impact of SoMe on measurable outcomes. The goal of this study was to quantify the impact of a dedicated SoMe strategy on engagement metrics for surgical research. METHODS: A retrospective review of a peer-reviewed surgical journal's Twitter microblog platform (@ColorectalDis) was performed from 6/2015 to 4/2021. A formal SoMe strategy was introduced in September 2018. Data were stratified into 2 time periods: pre-intervention (6-2015 to 9-2018) and post-SoMe intervention (9-2018 to 4-2021). The main outcome was the impact of the SoMe strategy on user engagement with the Twitter platform, journal, and traditional journal metrics. Twitter Analytics and Twitonomy were used to analyse engagement. RESULTS: From conception to analysis, the microblog published 1198 original tweets, generating 5 million impressions and 231,000 engagements. Increased account activity (increased tweets published per month-5.51 vs 28.79; p < 0.01) was associated with significant engagement growth, including new monthly followers (213 vs 38; p < 0.01) and interactions with posted articles (4,096,167 vs 269,152; p < 0.01). Article downloads increased twenty-fold post-SoMe intervention (210,449 vs 10,934; p < 0.01), with significant increases in traditional journal metrics of new subscribers (+11%), article submissions (+24%), and impact factor (+0.9) (all p < 0.01). CONCLUSION: SoMe directly impacts traditional journal metrics in surgical research. By examining the patterns of user engagement between SoMe and journal sites, the growing beneficial impact of a structured social media strategy and SoMe as an educational tool is demonstrated.

BACKGROUND: Anorectal cases may be a common gateway to the opioid epidemic. Opioid reduction is inherent in enhanced recovery after surgery (ERAS) protocols, but little work has evaluated ERAS in these cases. OBJECTIVE: To determine if ERAS could reduce postoperative opioid utilization in ambulatory anorectal surgery without sacrificing patient pain or satisfaction. METHODS: A randomized controlled trial assigned ambulatory anorectal patients to ERAS (experimental) or routine care (surgeon's choice) for pain management (control) over 30-days postoperatively. Primary outcome was overall days of opioid use. Secondary outcomes included pain and satisfaction scores over multiple time points and new persistent opioid use. The Visual Analog Scale, Functional Pain Scale, and EQ-5D-3L measured patient-reported pain and satisfaction. Univariate analysis compared outcomes overall and at individual time points. Two-way mixed ANOVA evaluated pain and satisfaction measures between groups and over time. RESULTS: Thirty-two patients were randomized into each arm (64 total). The control group consumed significantly more opioids after discharge (median 121.3MME vs 23.5MME, P < 0.001). Significantly more control patients requested additional narcotics (Pâ = â0.004), made unplanned calls (P = 0.009), and had unplanned clinic visits (P = 0.003). The control group had significantly more days on opioids (mean 14.4 vs 2.2, P < 0.001). Three control patients (9.4%) versus no experimental patients had new persistent opioid use. The mean global health, EQ5D-3L, Visual Analog Scale, and Functional Pain scores were comparable between groups over time. CONCLUSIONS: An ERAS protocol in ambulatory anorectal surgery is feasible, and resulted in reduced opioid use, and healthcare utilization, with no difference in pain or patient satisfaction. This challenges the paradigm that extended opioids are needed for effective postoperative pain management.

BACKGROUND: Decision-making under uncertainty may be influenced by an individual's personality. The primary aim was to explore associations between surgeon personality traits and colorectal anastomotic decision-making. METHODS: Colorectal surgeons worldwide participated in a two-part online survey. Part 1 evaluated surgeon characteristics using the Big Five Inventory to measure personality (five domains: agreeableness; conscientiousness; extraversion; emotional stability; openness) in response to scenarios presented in Part 2 involving anastomotic decisions (i.e. rejoining the bowel with/without temporary stomas, or permanent diversion with end colostomy). Anastomotic decisions were compared using repeated-measure ANOVA. Mean scores of traits domains were compared with normative data using two-tailed t tests. RESULTS: In total, 186 surgeons participated, with 127 surgeons completing both parts of the survey (68.3 per cent). One hundred and thirty-one surgeons were male (70.4 per cent) and 144 were based in Europe (77.4 per cent). Forty-one per cent (77 surgeons) had begun independent practice within the last 5 years. Surgeon personality differed from the general population, with statistically significantly higher levels of emotional stability (3.25 versus 2.97 respectively), lower levels of agreeableness (3.03 versus 3.74), extraversion (2.81 versus 3.38) and openness (3.19 versus 3.67), and similar levels of conscientiousness (3.42 versus 3.40 (all P <0.001)). Female surgeons had significantly lower levels of openness (P <0.001) than males (3.06 versus 3.25). Personality was associated with anastomotic decision-making in specific scenarios. CONCLUSION: Colorectal surgeons have different personality traits from the general population. Certain traits seem to be associated with anastomotic decision-making but only in specific scenarios. Further exploration of the association of personality, risk-taking, and decision-making in surgery is necessary.

AIM: Stage II colon cancers are a heterogeneous category, with controversy over use of adjuvant chemotherapy (AC). Patients with high-risk features may benefit from AC to improve overall survival (OS). Current guidelines do not routinely recommend AC in low-risk cases, but the actual use and benefit on OS in this cohort have not been fully examined on a national scale. We aimed to evaluate the use and impact of AC on OS in low-risk Stage II colon cancer. METHODS: The national cancer database was reviewed for Stage II colon cancers undergoing curative resection (2010-2015). Cases with preoperative radio-chemotherapy or high-risk features were excluded. Cases were stratified into 'AC' and 'no AC' cohorts, and then propensity score matched. Kaplan-Meier and Cox regression analysed OS. The main outcome measures were the incidence and impact of AC on OS in low-risk Stage II colon cancer. RESULTS: Of 39 926 patients evaluated, 8.2% (n = 3275) received AC. Matching resulted in 3275 cases per cohort. AC significantly improved 1-, 3- and 5-year OS versus no AC (P = 0.0017). The 5-year absolute risk reduction was 2.6%, relative risk reduction 12%, with a number needed to treat of 38. In the Cox model, AC remained significantly associated with increased OS (hazard ratio 0.816; 95% CI 0.713-0.934; P < 0.003). CONCLUSIONS: From this dataset, AC was associated with improved OS in low-risk Stage II disease. These findings from a large-scale sample question current guidelines and the need for better risk stratification. Further study with more robust variables is warranted to determine AC best practices.

BACKGROUND: Amid increasing awareness of early-onset colorectal cancer (CRC), guidelines in the United States (US) recently lowered the recommended routine CRC screening age from 50 to 45 in average-risk individuals. There are little data on the number of patients in this age group diagnosed with CRC prior to these changes. Our objective was to audit the historic CRC case trends and impact of CRC in the 45-to-50-year-old category prior to new screening recommendations. METHODS: Colorectal adenocarcinoma cases in 45-to-50-year-old patients were queried from the NCDB (2004-2017). Cases were stratified by sex, race, and site. The disability-adjusted lost years (DALY) and lost earnings were estimated. The average annual percentage changes (AAPC) of CRC incidence were estimated using jointpoint analysis. The main outcome measures were DALY and lost earnings. Secondary outcome measures were the 2004-2017 AAPC and the cumulative incidence of potential CRC cases in the 45-to-50 cohort through 2030 without guideline changes. RESULTS: 67,442 CRC patients in the 45-to-50 demographic were identified. The CRC burden resulted 899,905 DALY and $17 billion in lost earnings. The 2004-2017 AAPC was 1.6%, with an estimated 13-year increase of 25%. There were sex-, race-, and anatomic site-specific discrepancies with estimated 13-year increases of 30% for males, 110% for American Indian/ Alaska Natives/ Asian American/ Pacific Islander races, and 31% for rectal cancer by 2030. CONCLUSION: CRC has been steadily increasing in the 45-to-50 age group, with tremendous disability and cost ensuing. There is great potential benefit from lowering the recommended routine CRC screening age to 45. Targeted intervention could ensure the most vulnerable segments benefit from the new guidelines, in both reducing the incidence and improving survivorship in CRC patients.

BACKGROUND: As one of the 12 clinical pathways of the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) Masters Program, the Colorectal Pathway intends to deliver didactic content organized along 3 levels of performance (competency, proficiency and mastery) each represented by an anchoring procedure (laparoscopic right colectomy, laparoscopic left/sigmoid colectomy, and intracorporeal anastomosis during minimally invasive (MIS) ileocecal or right colon resection). In this article, the SAGES Colorectal Task Force presents focused summaries of the top 10 seminal articles selected for laparoscopic right colectomy which surgeons should be familiar with. METHODS: Using a systematic literature search of Web of Science, the most cited articles on laparoscopic right colectomy were identified, reviewed, and ranked by the SAGES Colorectal Task Force and invited subject experts. Additional articles not identified in the literature search were included if deemed impactful by expert consensus. The top 10 ranked articles were then summarized, with emphasis on relevance and impact in the field, findings, strengths and limitations, and conclusions. RESULTS: The top 10 seminal articles selected for the laparoscopic right colectomy anchoring procedure include articles on surgical techniques for benign and malignant disease, with anatomical and video illustrations, comparative outcomes of laparoscopic vs open colectomy, variations in technique with impact on clinical outcomes, and assessment of the learning curve. CONCLUSIONS: The top 10 seminal articles selected for laparoscopic right colectomy illustrate the diversity both in content and format of the educational curriculum of the SAGES Masters Program to support practicing surgeon progression to mastery within the Colorectal Pathway.

BACKGROUND: Positive circumferential resection margin is a predictor of local recurrence and worse survival in rectal cancer. National programs aimed to improve rectal cancer outcomes were first created in 2011 and continue to evolve. The impact on circumferential resection margin during this time frame has not been fully evaluated in the United States. OBJECTIVE: The purpose of this study was to determine the incidence and predictors of positive circumferential resection margin after rectal cancer resection, across patient, provider, and tumor characteristics. DESIGN: This was a retrospective cohort study. SETTINGS: The study was conducted using the National Cancer Database, 2011-2016. PATIENTS: Adults who underwent proctectomy for pathologic stage I to III rectal adenocarcinoma were included. MAIN OUTCOME MEASURES: Rate and predictors of positive circumferential resection margin, defined as resection margin ≤1 mm, were measured. RESULTS: Of 52,620 cases, circumferential resection margin status was reported in 90% (n = 47,331) and positive in 18.4% (n = 8719). Unadjusted analysis showed that patients with positive circumferential resection margin were more often men, had public insurance and shorter travel, underwent total proctectomy via open and robotic approaches, and were treated in Southern and Western regions at integrated cancer networks (all p < 0.001). Multivariate analysis noted that positive proximal and/or distal margin on resected specimen had the strongest association with positive circumferential resection margin (OR = 15.6 (95% CI, 13.6-18.1); p < 0.001). Perineural invasion, total proctectomy, robotic approach, neoadjuvant chemoradiation, integrated cancer network, advanced tumor size and grade, and Black race had increased risk of positive circumferential resection margin (all p < 0.050). Laparoscopic approach, surgery in North, South, and Midwest regions, greater hospital volume and travel distance, lower T-stage, and higher income were associated with decreased risk (all p < 0.028). LIMITATIONS: This was a retrospective cohort study with limited variables available for analysis. CONCLUSIONS: Despite creation of national initiatives, positive circumferential resection margin rate remains an alarming 18.4%. The persistently high rate with predictors of positive circumferential resection margin identified calls for additional education, targeted quality improvement assessments, and publicized auditing to improve rectal cancer care in the United States.

PREDICTORES PARA UN MARGEN POSITIVO DE RESECCIN CIRCUNFERENCIAL EN EL CNCER DE RECTO UNA AUDITORA VIGENTE DE LA BASE DE DATOS NACIONAL DE CANCER: ANTECEDENTES:El margen positivo de resección circunferencial es un predictor de recurrencia local y peor sobrevida en el cáncer de recto. Los programas nacionales destinados a mejorar los resultados del cáncer de recto se crearon por primera vez en 2011 y continúan evolucionando. La repercusión del margen de resección circunferencial durante este período de tiempo no se ha evaluado completamente en los Estados Unidos.OBJETIVO:Determinar la incidencia y los predictores para un margen positivo de resección circunferencial posterior a la resección del cáncer de recto, según las características del paciente, el proveedor y el tumor.DISEÑO:Estudio de cohorte retrospectivo.AMBITO:Base de datos nacional de cáncer, 2011-2016.PACIENTES:Adultos que se sometieron a proctectomía por adenocarcinoma de recto con un estadío por patología I-III.PRINCIPALES VARIABLES EVALUADAS:Tasa y predictores para un margen positivo de resección circunferencial, definido como margen de resección ≤ 1 mm.RESULTADOS:De 52,620 casos, la condición del margen de resección circunferencial se informó en el 90% (n = 47,331) y positivo en el 18.4% (n = 8,719). El análisis no ajustado mostró que los pacientes con margen positivo de resección circunferencial se presentó con mayor frecuencia en hombres, tenían un seguro social y viajes más cortos, se operaron de proctectomía total abierta y robótica, y fueron tratados en las regiones del sur y el oeste en redes integradas de cáncer (todos p <0,001). El análisis multivariado destacó que el margen proximal y / o distal positivo de la pieza resecada tenía la asociación más fuerte con el margen postivo de resección circunferencial (OR 15,6; IC del 95%: 13,6-18,1, p <0,001). La invasión perineural, la proctectomía total, el abordaje robótico, la quimioradioterapia neoadyuvante, la red de cáncer integrada, el tamaño y grado del tumor avanzado y la raza afroamericana tenían un mayor riesgo de un margen de una resección positiva circunferencial (todos p <0,050). El abordaje laparoscópico, la cirugía en las regiones Norte, Sur y Medio Oeste, un mayor volumen hospitalario y distancia de viaje, estadio T más bajo y mayores ingresos se asociaron con una disminución del riesgo (todos p <0,028).LIMITACIONES:Estudio de cohorte retrospectivo con variables limitadas disponibles para análisis.CONCLUSIONES:A pesar del establecimiento de iniciativas nacionales, la tasa de margen positivo de resección circunferencial continúa siendo alarmante, 18,4%. El índice continuamente elevado junto a los predictores de un margen positivo de resección circunferencial hace un llamado para una mayor educación, evaluaciones específicas de mejora de la calidad y difusión de las auditorías para mejorar la atención del cáncer de recto en los Estados Unidos.

BACKGROUND: There is wide variation in gender distribution in colorectal surgery across different European countries. OBJECTIVE: This study aimed to evaluate female representation, implicit bias, and members' perception on female participation and representation at the European Society of Coloproctology 2017 annual scientific meeting. DESIGN: This was a retrospective mixed-methods cross-sectional observational study. SETTINGS: The study was conducted using data from the 2017 European Society of Coloproctology annual scientific meeting program and attendees. MAIN OUTCOME MEASURES: The primary outcome measure was the percentage of female speakers in the formal program and assessment for implicit bias. Secondary outcomes were the percentage of women attending the conference, the percentage of women serving on committees, and the results of the online survey. METHODS: Female representation was retrospectively quantified by role, session type, and topic. Implicit bias was measured classifying the introductions of speakers by moderators as formal (using a professional title) or informal (using name only), then further stratified by gender. An online survey was disseminated and analyzed to investigate the members' perception as a benchmark analysis. RESULTS: Disparities were found between sexes, with fewer women attending the conference (25%), serving as session chairs (8%), speakers (21%), and on committees (10%) compared with men. There were no differences across sexes regarding the formal or informal introduction. The survey among our members showed that significantly fewer women felt equally endorsed within the society compared with men (33% versus 63%; p < 0.001). LIMITATIONS: The retrospective design with data available to be analyzed was limited by the sessions recorded (27/49) and survey respondents (28%). CONCLUSIONS: Female representation within European Society of Coloproctology as chair, speaker, attendee, and committee member was much lower than male representation, both in absolute numbers and relative to membership. Greater awareness of this disparity and inclusiveness are aims of our society. The impact of these initiatives will be determined by reevaluating these metrics at the 2020 annual meeting.

REPRESENTACIN Y POSICIN FEMENINA EN LA SOCIEDAD EUROPEA DE COLOPROCTOLOGA BASADA EN LOS HECHOS Y LAS OPINIONES DE SUS MIEMBROS: ANTECEDENTES:Existe una amplia variabilidad en la distribución de géneros en la cirugía colorrectal en los diferentes países de Europa.OBJETIVO:Evaluar la representación femenina, el sesgo implícito y la percepción de los miembros sobre la participación y representación femenina en el 12° Congreso científico anual de la Sociedad Europea de Coloproctología.DESIGN:Este fué un estudio observacional retrospectivo de métodos mixtos transversales.AJUSTES:Los análisis se realizaron utilizando los datos del programa cintífico de la reunión y los datos de los presentes en el Congreso de la ESCP en 2017.MEDIDAS PRINCIPALES DE RESULTADOS:La principal medida en el resultado fue el porcentaje de disertantes femeninas en el programa definitivo y la evaluación del sesgo implícito. Los resultados secundarios fueron el porcentaje de mujeres que asistieron a la conferencia, trabajaron en los comités y los resultados de la encuesta informática.METODOS:La representación femenina se cuantificó retrospectivamente según el rol, tipo de sesión y temas. Se midió el sesgo implícito clasificando las introducciones de los disertantes por parte de los moderadores de manera formal (usando un título profesional) o informal (usando solamente el nombre), y luego fueron estratificadas por género. Se difundió y analizó una encuesta informática para investigar la percepción de los miembros como análisis de referencia.RESULTADOS:Se encontraron disparidades de género, con menos mujeres presentes en la conferencia (25%), obrando como presidentes de sesión (8%), como disertantes (21%) y como miembros de comités (10%) comparadas con los hombres. No hubo diferencia entre sexos con respecto a la introducción formal o informal. La encuesta informática entre los miembros mostró significativamente que menos mujeres se sentían respaldadas igualitariamente dentro de la sociedad comparadas con los hombres (33% frente a 63%, p<0.001).LIMITACIONES:Diseño retrospectivo de datos limitados a las sesiones grabadas (27/49) y a los encuestados (28%) disponibles para el análisis.CONCLUSIONES:La representación femenina dentro de la Sociedad Europea de Coloproctología como presidente, disertante, asistente ó como miembro del comité fué mucho menor que la representación masculina, tanto en números absolutos como en relación con la membresía. Crear una mayor conciencia de esta disparidad de inclusión son prioridad en nuestra sociedad. El impacto de estas iniciativas se determinará re-evaluando estas variables en reuniones futuras.

AIM: Colorectal cancer staging has evolved to define N1c as the presence of tumour deposits without concurrent positive lymph nodes. Work to date reports poor prognosis in N1c colon cancer, with Stage III categorization and adjuvant chemotherapy (AC) recommended. No study has yet evaluated the prevalence, treatment compliance or treatment-related outcomes on a national scale. We aimed to evaluate the prevalence of N1c colon cancer, use, outcomes and factors associated with AC in the USA. METHOD: The National Cancer Database was reviewed for N1cM0 colon adenocarcinomas that underwent resection from 2010 to 2016. Cases were stratified into 'AC' or 'no AC' cohorts. The Kaplan-Meier method was used to estimate overall survival (OS) and compare the AC and no AC cohorts using the log-rank test. Multivariable logistic regression identified factors associated with AC. The main outcome measures were the prevalence and factors associated with AC use and its impact in N1c disease. RESULTS: Of the 5684 (1.59% of 357 752) colon adenocarcinomas that were N1c, 55% (n = 3071) received AC. AC significantly improved 1-, 3- and 5-year OS compared with no AC (96.2%, 80%, 67.4% and 72.9%, 48.5%, 33.8%, respectively; P < 0.001). Compared with the no AC group, AC patients were younger, had less comorbidity, were of the male gender and received minimally invasive surgery at an academic treatment centre (all P < 0.05). Socioeconomic and procedural factors significantly impacted the use of AC. CONCLUSION: In the USA, AC is underutilized in N1c colon cancer despite significantly improved OS. Socioeconomic and procedural factors associated with AC were identified, highlighting disparities in AC use and opportunities to improve oncological outcomes and survival.
