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.

Conventional endoscopy is limited in its ability to examine the small bowel and perform long-term monitoring due to the risk of infection and tissue perforation. Wireless Capsule Endoscopy (WCE) is a painless and non-invasive method of examining the body's internal organs using a small camera that is swallowed like a pill. The existing active locomotion technologies do not have a practical localization system to control the capsule's movement within the body.

Colorectal cancer (CRC) is a leading cause of cancer mortality, with many patients presenting with malignant colorectal obstruction (MCO). Self-expandable metal stents (SEMSs) have emerged as a minimally invasive key intervention, both as a bridge to surgery (BTS) in curative setting sand for palliation in advanced disease. This review aims to provide an evidence-based analysis of SEMS indications, contraindications, and efficacy across curative and palliative contexts, with focus on long-term outcomes.

Background: Tamuzimod (VTX002) is a selective sphingosine 1-phosphate receptor 1 modulator in development for ulcerative colitis. We aimed to assess the safety and efficacy of tamuzimod in patients with moderately-to-severely active ulcerative colitis.
Methods: This double-blind, randomised, placebo-controlled, phase 2 induction trial was conducted at 122 centres across 15 countries in Asia, Europe, and North America.

Rationale: Triple gallbladder is a rare congenital anatomical abnormality because of the incomplete regression of rudimentary bile ducts and is often not found until it is accidentally detected during imaging research.
Patient Concerns: We report a rare case of triple gallbladder malformation and review the English literature on biliary tract variation caused by gallbladder malformation. The diagnosis, treatment, and postoperative situation of the patients were summarized and analyzed.
