ABSTRACT
BACKGROUND: Advanced endoscopy can be used for the complete removal of large colorectal polyps. To date, few surgeons perform advanced endoscopy, and it is unknown how many procedures are needed to reach proficiency. OBJECTIVE: This study aimed to determine the learning curve for colorectal advanced endoscopy. DESIGN: Retrospective. SETTING: Tertiary referral center. PATIENTS: We queried a prospectively maintained institutional database of advanced endoscopy performed by a high-volume colorectal surgeon between 2011 and 2018. MAIN OUTCOME MEASURES: Advanced endoscopy characteristics were compared for 6 chronological intervals. Primary end points were the rates of complications and polyp recurrence. Secondary end point was the change in polyp removal rate (mm/h) over time. RESULTS: A total of 207 patients underwent advanced endoscopy for a single colorectal polyp. The median polyp size was 30 (4-70) mm, 61.5% were located in the right colon, and 8.8% were malignant. The mean procedure time was 77 (range, 16-320) minutes. Immediate colon resection occurred in 25 patients because of suspicion of cancer or concern for perforation and was excluded from the learning curve analysis. The remaining 182 advanced endoscopy procedures were divided into intervals of 30 procedures. The median removal rate was highest in the last interval and in the endoscopy suite. A removal rate of 30 mm/h was achieved after performing 100 cases. The complication rate (bleeding or return to operating room) was 12.1% and was similar across intervals. The readmission rate was 11.5%, and 6.6% of 6-month follow-up colonoscopies showed polyp recurrence at the resection site. LIMITATIONS: Retrospective design and single surgeon. CONCLUSION: The learning curve for achieving proficiency with advanced endoscopy in the colon and rectum required a minimum of 100 cases with a low complication rate, low polyp recurrence rate, high en bloc resection rate, and a polyp removal rate of 30 mm/h.

Hasta la fecha, pocos cirujanos realizan endoscopia avanzada y se desconoce cuántos procedimientos se necesitan para alcanzar la competencia.OBJETIVO:Determinar la curva de aprendizaje de la endoscopia colorrectal avanzada.DISEÑO:Retrospectivo.AJUSTE:Centro de referencia terciario.PACIENTES:Consultamos una base de datos institucional mantenida prospectivamente de endoscopia avanzada realizada por un cirujano colorrectal de alto volumen entre 2011 y 2018.PRINCIPALES MEDIDAS DE RESULTADO:Se compararon las características de la endoscopia avanzada en seis intervalos cronológicos. Los puntos finales primarios fueron las tasas de complicaciones y recurrencia de pólipos. El criterio de valoración secundario fue el cambio en la tasa de eliminación de pólipos (mm/h) a lo largo del tiempo.RESULTADOS:Un total de 207 pacientes se sometieron a una endoscopia avanzada por un solo pólipo colorrectal. La mediana del tamaño de los pólipos fue de 30 (4-70) mm, el 61,5% se ubicaron en el colon derecho y el 8,8% fueron malignos. El tiempo medio del procedimiento fue de 77 (rango: 16-320) minutos. La resección inmediata del colon ocurrió en 25 pacientes debido a la sospecha de cáncer o preocupación por la perforación y fueron excluidos del análisis de la curva de aprendizaje. Los restantes 182 procedimientos de endoscopia avanzada se dividieron en intervalos de 30 procedimientos. La mediana de la tasa de extirpación fue más alta en el último intervalo y en la sala de endoscopia. Se logró una tasa de extirpación de 30 mm/hr después de realizar 100 casos. La tasa de complicaciones (sangrado o retorno al quirófano) fue del 12,1% y fue similar en todos los intervalos. La tasa de reingreso fue del 11,5% y el 6,6% de las colonoscopias de seguimiento a los 6 meses mostraron recurrencia de pólipos en el sitio de la resección.LIMITACIONES:Diseño retrospectivo, cirujano único.CONCLUSIÓN:La curva de aprendizaje para lograr el dominio de la endoscopia avanzada en el colon y el recto requiere un mínimo de 100 casos con una baja tasa de complicaciones, baja tasa de recurrencia de pólipos, alta tasa de resección en bloque y una tasa de eliminación de pólipos de 30 mm/h.

Background: There has been an increase in opioid usage and opioid-related deaths. Opioids prescribed to surgical patients have similarly increased. The aim of this study was to assess opioid consumption in patients undergoing laparoscopic appendectomy (LA) and laparoscopic cholecystectomy (LC) and to determine whether a standardized prescription could affect opioid consumption without affecting patient satisfaction. Methods: Patients undergoing LA or LC were recruited prospectively during 2 time periods (April to June 2017 and November 2017 to January 2018). In the first phase, surgeons continued their usual postoperative analgesia prescribing patterns. In the second phase, a standardized prescription was implemented. Patients were contacted by telephone and a questionnaire was completed for both phases of the study. The primary outcome was the quantity of opioids prescribed and consumed. Results: In the first phase, 166 patients who underwent LC or LA were recruited. The median number of prescribed opioid tablets was 20 and the median number consumed was 2. Ninety-five percent of patients reported satisfaction with their analgesia. Based on these results, a standardized prescription for multimodal analgesia was implemented for the second phase, consisting of 10 opioid tablets. In the second phase, 129 patients who underwent LA or LC were recruited. There was a significant decrease in the median number of opioid pills filled (10) and consumed (0), with no difference in reported satisfaction with analgesia. Conclusion: Patients are prescribed an excess of opioids after LA or LC. Implementation of a standardized prescription based on a quality improvement intervention was effective at decreasing the number of opioids prescribed and consumed.
Contexte: On a observé une augmentation de la consommation d'opioïdes, ainsi qu'une hausse des décès associés à ces substances. On a aussi constaté une augmentation semblable dans la prescription d'opioïdes aux patients ayant subi une chirurgie. La présente étude visait à évaluer la consommation d'opioïdes chez les personnes ayant subi une appendicectomie par laparoscopie (AL) ou une cholécystectomie par laparoscopie (CL), de même qu'à déterminer si une ordonnance normalisée pouvait modifier la consommation d'opioïdes sans nuire à la satisfaction des patients. Méthodes: Des patients devant subir une AL ou une CL ont été recrutés de façon prospective entre avril et juin 2017 et entre novembre 2017 et janvier 2018. Durant la première phase de l'étude, les chirurgiens ont maintenu leurs habitudes de prescription d'analgésie postopératoire. Durant la deuxième phase, toutefois, ils devaient avoir recours à une ordonnance normalisée. Dans les 2 phases de l'étude, les patients ont été joints par téléphone et un questionnaire a été rempli. Le principal résultat à l'étude était la quantité d'opioïdes prescrits et consommés. Résultats: Pour la première phase de l'étude, 166 patients ont été recrutés. Les nombres médians de comprimés prescrits et consommés étaient de 20 et de 2, respectivement. De tous les patients, 95 % se sont dits satisfaits de leur analgésie. Pour la deuxième phase, une ordonnance normalisée d'analgésie multimodale, qui comptait 10 comprimés, a été mise en place, et 129 patients ont été recrutés. On a alors observé une diminution significative du nombre médian de comprimés remis (10) et consommés (0), et aucune différence quant au degré de satisfaction déclaré. Conclusion: Les patients se voient prescrire trop d'opioïdes après une AL ou une CL. La création d'une ordonnance normalisée dans le cadre d'une intervention d'amélioration de la qualité a réduit efficacement le nombre de comprimés d'opioïdes prescrits et consommés.

BACKGROUND: Risk factors for pouch survival may or may not have a linear relationship with pouch loss over time. Conditional survival is a method to describe these nonlinear time-to-event relationships by reporting the expected survival at various time points. OBJECTIVE: The aim of this study was to calculate conditional pouch survival based on occurrence of risk factors for pouch loss. DESIGN: This was a retrospective study from an institutional database. SETTINGS: The study was conducted at the Cleveland Clinic Foundation. PATIENTS: Patients with ulcerative or indeterminate colitis who underwent index IPAA construction between 1986 and 2016 were included. MAIN OUTCOME MEASURES: Patients were stratified based on postoperative anastomotic leak, abscess, or fistula occurrence. The Kaplan-Meier method with conditional survival was used to estimate overall and cause-specific survival at 10 years. RESULTS: A total of 3468 patients underwent IPAA during the study period. The overall 10-year pouch survival rate was 0.94 (95% CI, 0.93-0.95), and after 1 year the conditional pouch survival increased to 0.95 (95% CI, 0.94-0.96), after 3 years to 0.97 (95% CI, 0.96-0.98), and after 5 years to 0.98 (95% CI, 0.98-0.99). A total of 122 patients (3.5%) developed anastomotic leak, and the 10-year IPAA survival in patients with leak was 0.85 (95% CI, 0.77-0.93). In this group, after 1 year of pouch survival, the conditional pouch survival increased to 0.89 (95% CI, 0.82-0.96) and after 3 years to 0.98 (95% CI, 0.94-1.00). A similar pattern was seen for IPAA with postoperative abscess. The conditional survival curve was stable over time for patients with a fistula. LIMITATIONS: This was a retrospective, single-institution study. CONCLUSIONS: Overall conditional pouch survival improved over time for patients with postoperative anastomotic leak and abscess. These novel findings can be useful to counsel patients regarding expectations for long-term pouch survival even if they develop leaks and abscesses.

SUPERVIVENCIA CONDICIONAL DESPUÉS DE ANASTOMOSIS CON BOLSA ÍLEO ANAL, PARA COLITIS ULCERATIVA E INDETERMINADA: ¿LA SOBREVIDA DE LA BOLSA A LARGO PLAZO, MEJORA O EMPEORA CON EL TIEMPO?: Los factores de riesgo para la sobrevida de la bolsa, pueden o no tener una relación lineal con la pérdida de la bolsa y con el tiempo. La supervivencia condicional es un método para describir estas relaciones no lineales de tiempo, hasta el evento informando la supervivencia esperada en varios puntos de tiempo.El objetivo de este estudio fue calcular la supervivencia condicional de la bolsa, en función de aparición de factores de riesgo para la pérdida de bolsa.Estudio retrospectivo de una base de datos institucional.Cleveland Clinic Foundation.Pacientes con colitis ulcerativa o indeterminada, sometidos a una anastomosis de bolsa íleo anal, de 1986 a 2016.Los pacientes fueron estratificados en función de la fuga anastomótica postoperatoria, absceso o aparición de fístula. El método de Kaplan Meier con supervivencia condicional, se utilizó para estimar la supervivencia general y la causa específica a los 10 años.Un total de 3.468 pacientes fueron sometidos a anastomosis ileal con bolsa anal durante el período de estudio. La tasa de supervivencia global de la bolsa a 10 años, fue de 0,94 (0,93 a 0,95), y después de 1 año, la supervivencia condicional de la bolsa aumentó a 0,95 (0,94 a 0,96), después de 3 años a 0,97 (0,96 a 0,98) y después de 5 años a 0.98 (0.98 - 0.99). Un total de 122 (3,5%) pacientes desarrollaron fuga anastomótica, y la supervivencia de la anastomosis de bolsa íleo anal a 10 años en pacientes con fuga fue de 0,85 (IC del 95%: 0,77 a 0,93). En este grupo, después de 1 año de supervivencia de la bolsa, la supervivencia condicional de la bolsa aumentó a 0,89 (IC del 95%: 0,82 a 0,96), y después de 3 años a 0,98 (IC del 95%: 0,94 a 1). Se observó un patrón similar para la anastomosis de bolsa íleo anal con absceso postoperatorio. La curva de supervivencia condicional fue estable en el tiempo para los pacientes con una fístula.Estudio retrospectivo, de una sola institución.La supervivencia condicional global de la bolsa, mejoró con el tiempo para pacientes con fuga anastomótica postoperatoria y absceso. Estos nuevos hallazgos pueden ser útiles para aconsejar a los pacientes con respecto a las expectativas de supervivencia de la bolsa a largo plazo, incluso si desarrollan fugas y abscesos.

PURPOSE: Patients with rectal cancer (RCa) and prior radiation for prostate cancer (PCa) are clinically complicated and may have worse outcomes than other RCa patients. This study investigates the impact of previous radiation for PCa on survival for patients with RCa. METHOD: We conducted a population-based study identifying men who underwent surgical treatment of RCa from 2002 to 2010. Patients were classified into three cohorts: no prior PCa, prior PCa treated without radiotherapy, and prior PCa treated with radiotherapy. The primary outcome was overall survival. Secondary outcomes included RCa surgical approach, ICU admission, length of stay, ER visits, and delayed formation of a new stoma. RESULTS: Seven thousand ninety-six men underwent surgery for RCa; 6867 patients had no prior PCa, 58 had prior PCa treated without radiotherapy, and 171 had prior PCa treated with radiotherapy. The 5-year overall survival was 62% (95% CI 61-64%) for patients without prior PCa, 46% (95% CI 25-65%) for patients with prior PCa treated without radiotherapy, and 42% (95% CI 29-54%) for patients with prior PCa treated with radiotherapy (p < 0.0001). In multivariable analysis, patients with prior PCa treated with radiotherapy were at increased risk of death (aHR 1.38, 95% CI 1.12-1.69) compared to those without prior PCa. Furthermore, patients with prior PCa treated with radiotherapy had a significantly increased risk of resection with permanent stoma. CONCLUSIONS: Prior radiotherapy for PCa is a poor prognostic factor in RCa patients with significantly increased risk of death. Additionally, patients with prior radiotherapy for PCa are more likely to require a permanent stoma.

BACKGROUND: Over the past 2 decades, there has been an increase in opioid use and subsequently, opioid deaths. The amount of opioid prescribed to surgical patients has also increased. The aim of this systematic review was to determine postdischarge opioid consumption in surgical patients compared with the amount of opioid prescribed. Secondary outcomes included adequacy of pain control and disposal methods for unused opioids. OBJECTIVE: The objective of this study is to characterize postdischarge opioid consumption and prescription patterns in surgical patients. METHODS: A systematic search in MEDLINE and EMBASE identified 11 patient survey studies reporting on postdischarge opioid use in 3525 surgical patients. RESULTS: The studies reported on a variety of surgical operations, including abdominal surgery, orthopedic procedures, tooth extraction, and dermatologic procedures. The majority of patients consumed 15 pills or less postdischarge. The proportion of used opioids ranged from 5.6% to 59.1%, with an outlier of 90.1% in pediatric spinal fusion patients. Measured pain scores of those taking opioids ranged between 2 and 5 out of 10 and the majority of patients were satisfied with their pain control. Seventy percent of patients kept the excess opioids. Where planned disposal methods were reported, between 4% and 59% of patients planned proper disposal. CONCLUSION: This study suggests that surgical patients are using substantially less opioid than prescribed. There is a lack of awareness regarding proper disposal of leftover medication, leaving excess opioid that may be used inappropriately by the patient or others. Education for providers and clinical practice guidelines that provide guidance on prescription of outpatient of opioids are required.

PUPRPOSE: Benign polyps that are technically challenging and unsafe to remove via polypectomy are known as complex polyps. Concerns regarding safety and completeness of resection dictate they undergo advanced endoscopic techniques, such as endoscopic mucosal resection or surgery. We provide a comprehensive overview of complex polyps and current treatment options. METHODS: A review of the English literature was conducted to identifyarticles describing the management of complex polyps of the colon and rectum. RESULTS: Endoscopic mucosal resection is the standard of care for the majority of complex polyps. Only polyps that fail endoscopic mucosal resection or are highly suspicious of invasive cancer but which cannot be removed endoscopically warrant surgery. CONCLUSION: Several factors influence the treatment of a complex polyp; therefore, there cannot be a "one-size-fitsall" approach. Treatment should be tailored to the lesion's characteristics, the risk of adverse events, and the resources available to the treating physician.

BACKGROUND: Locally advanced colon cancer is considered a relative contraindication for laparoscopic resection, and clinical trials addressing the oncologic safety are lacking. OBJECTIVE: The aim of this study was to synthesize the oncologic outcomes associated with laparoscopic versus conventional open surgery for locally advanced colon cancers. DATA SOURCES: We systematically searched Medline, Embase, Central, and ClinicalTrials.gov. STUDY SELECTION: Two reviewers independently screened the literature for controlled trials or observational studies comparing curative-intent laparoscopic and open surgery for colon cancer. Studies were included if it was possible to determine outcomes for the T4 colon cancers separately, either reported in the article or calculated with individual patient data. INTERVENTIONS: Included studies were systematically reviewed and assessed for risk of bias. Meta-analyses were done by using random-effects models. MAIN OUTCOME MEASURES: Outcomes of interest were disease-free survival, overall survival, resection margins, and lymph node harvest. RESULTS: Of 2878 identified studies, 5 observational studies met eligibility criteria with a total of 1268 patients (675 laparoscopic, 593 open). There was no significant difference in overall survival (HR, 1.28; 95% CI, 0.94-1.72), disease-free survival (HR, 1.20; 95% CI, 0.90-1.61), or positive surgical margins (OR, 1.16; 95% CI, 0.58-2.32) between the groups. The open group had a larger lymph node retrieval (pooled mean difference, 2.26 nodes; 95% CI, 0.58-3.93). The pooled rate of conversion from laparoscopy to an open procedure was 18.6% (95% CI, 9.3%-27.9%). LIMITATIONS: These results are limited by the inherent selection bias in the included nonrandomized studies. CONCLUSIONS: Based on the available literature, minimally invasive resection of selected locally advanced colon cancer is oncologically safe. There is a small increase in lymph node harvest with open resections, but it is unclear whether this is clinically significant. Surgeons should be prepared for a significant rate of conversion to laparotomy as required to perform en bloc resection.

BACKGROUND: Robotic surgery has emerged as a minimally invasive alternative to traditional laparoscopy. Robotic surgery addresses many of the technical and ergonomic limitations of laparoscopic surgery, but the literature regarding clinical outcomes in colorectal surgery is limited. We sought to compare robotic and laparoscopic colorectal resections with respect to 30-day perioperative outcomes. METHODS: The American College of Surgeons National Surgical Quality Improvement Program database was used to identify all patients who underwent robotic or laparoscopic colorectal surgery in 2013. We performed a logistic regression analysis to compare intraoperative variables and 30-day outcomes. RESULTS: There were 8392 patients who underwent laparoscopic colorectal surgery and 472 patients who underwent robotic colorectal surgery. The robotic cohort had a lower incidence of unplanned intraoperative conversion (9.5% v. 13.7%, p = 0.008). There were no significant differences between robotic and laparoscopic surgery with respect to other intraoperative and postoperative outcomes, such as operative duration, length of stay, postoperative ileus, anastomotic leak, venous thromboembolism, wound infection, cardiac complications and pulmonary complications. On multivariable analysis, robotic surgery was protective for unplanned conversion, while male sex, malignancy, Crohn disease and diverticular disease were all associated with open conversion. CONCLUSION: Robotic colorectal surgery has comparable 30-day perioperative morbidity to laparoscopic surgery and may decrease the rate of intraoperative conversion in select patients.
BACKGROUND: La chirurgie robotique est de plus en plus utilisée comme option de rechange peu effractive à la laparoscopie classique. La robotique permet de remédier à bon nombre des restrictions techniques et ergonomiques de la chirurgie laparoscopique, mais peu d'articles font état des résultats cliniques en chirurgie colorectale. Nous avons donc cherché à comparer les 2 techniques de résection colorectale en ce qui concerne les résultats peropératoires dans les 30 jours suivant l'intervention. METHODS: À l'aide de base de données du National Surgical Quality Improvement Program de l'American College of Surgeons, nous avons recensé tous les patients ayant subi une résection colorectale par chirurgie laparoscopique ou robotique en 2013. Nous avons ensuite mené une analyse de régression logistique pour comparer des variables peropératoires et les résultats après 30 jours. RESULTS: En tout, 8392 patients avaient subi une chirurgie colorectale par laparoscopie pendant la période visée, et 472 avaient subi une intervention par chirurgie robotique. Le second groupe avait une incidence plus faible de conversion peropératoire imprévue (9,5 % par rapport à 13,7 %; p = 0,008). On n'a relevé aucune différence significative entre les 2 types d'intervention quant aux autres résultats peropératoires et postopératoires, soit la durée de l'intervention, la durée du séjour à l'hôpital et la survenue d'un iléus, d'une fuite anastomotique, d'une thromboembolie veineuse, d'une infection de la plaie ou de complications cardiaques ou pulmonaires. D'après l'analyse multivariables, la chirurgie robotique préviendrait les conversions imprévues, tandis que le sexe masculin, la présence d'une tumeur maligne, la maladie de Crohn et la diverticulose colique étaient associés à une conversion peropératoire. CONCLUSION: Les taux de morbidité peropératoire après 30 jours pour une résection colorectale par chirurgie robotique et une intervention par chirurgie laparoscopique sont comparables. La chirurgie robotique pourrait de plus réduire le taux de conversion peropératoire chez certains patients.

We present a case report of colorectal cancer arising in a young patient with ulcerative colitis of only 6 years duration. The pathology was unusual with extensive pancolonic involvement in a lintitis plastica fashion. This case represents a clinical example where colon cancer occurred prior to the onset of recommended screening according to guidelines regarding patients with ulcerative colitis.

Elective abdominal surgery for inflammatory bowel disease is common. Surgery for Crohn's disease is not curative, and treatment must be individualized to the disease process. Surgery for ulcerative colitis generally is curative but consideration of patient-specific factors is important for staging of the procedure and determining whether ileal pouch-anal anastomosis is appropriate.

BACKGROUND: Regional variation in the use of surgery implies that there is uncertainty regarding appropriate use. The objectives of this study were to identify which surgical procedures are most commonly performed in the province of Ontario and measure the extent of variation in the use of surgical procedures across Ontario counties. METHODS: We used the Canadian Institute for Health Information Discharge Abstract Database, Same Day Surgery Database and National Ambulatory Care Reporting System to retrieve information on all inpatient and day surgery visits in Ontario between Apr. 1, 2002, and Mar. 31, 2011. We identified the 84 most common procedures according to Canadian Classification of Interventions codes. We calculated rates of use for each procedure throughout the 49 Ontario counties and then calculated measures of variation (quartile ratio and systematic component of variation) in use between the counties. RESULTS: Colonoscopy was the most commonly performed procedure during the study period, with an average adjusted rate of 2012 per 100 000 population. The procedure with the highest measure of variation was iridectomy, with a quartile ratio of 6.7, followed by colposcopy (5.2), cervical biopsy (4.2) and femoral arteriography (4.1). These procedures were less commonly performed. Common procedures such as colonoscopy, cataract extraction and vaginal delivery had lower quartile ratios. Analysis using the systematic component of variation as the measure of variation gave similar results. INTERPRETATION: Colonoscopy was the most commonly performed procedure in Ontario, and cataract extraction was the most common surgical procedure. Procedures with the highest measures of variation between counties tended to be those that occurred less commonly in Ontario, and common procedures were associated with less regional variation.
