Background: Patients with inflammatory bowel disease have an increased risk of colorectal cancer and are recommended to undergo increased surveillance compared to the general population. Currently, inadequate evidence exists to guide management of colonic dysplasia discovered during screening of inflammatory bowel disease patients.
Objective: The goal of this study was to determine the risk of colorectal cancer in patients with ulcerative colitis or Crohn's disease with dysplasia on colonoscopy.
Design: This was a retrospective study.
Setting: This study was conducted at a high-volume, quaternary referral center with an inflammatory bowel disease program.
Patients: Patients with a diagnosis of inflammatory bowel disease with colonoscopy within 6 months of colectomy were included.
Main Outcome Measures: The primary outcome measures included finding of colorectal cancer at time of colectomy.
Results: There were 621 patients, 233 with ulcerative colitis and 388 with Crohn's disease. Of ulcerative colitis patients, 25 had low-grade dysplasia on colonoscopy with 1 (4%) found to have colorectal cancer at colectomy. High-grade dysplasia was noted preoperatively in 14 and colorectal cancer was found in 4 (29%) after colectomy. Compared to no dysplasia, low-grade dysplasia did not increase the risk of colorectal cancer (OR 1.98, p = 0.47), but high-grade dysplasia had an increased risk (OR 19.0, p < 0.001) of colorectal cancer. For the 7 patients with Crohn's disease and low-grade dysplasia, colorectal cancer was found in 1 patient (14%) at colectomy. High-grade dysplasia was noted preoperatively in 4 patients with Crohn's Disease, and colorectal cancer was found in 3 patients (75%) after colectomy. Compared to no dysplasia, low-grade dysplasia did not increase the risk of colorectal cancer (OR 12.4, p = 0.88), but high-grade dysplasia did increase the risk of colorectal cancer (OR 223.2, p < 0.001).
Limitations: This study was limited by its retrospective review.
Conclusion: In both ulcerative colitis and Crohn's disease, low-grade dysplasia was not associated with colorectal cancer. High-grade dysplasia was associated with an increased risk of colorectal cancer at time of colectomy. While continued surveillance may be appropriate for low-grade dysplasia, high-grade dysplasia necessitates surgical resection given the high likelihood of colorectal cancer.

Displasia De Alto Grado En La Enfermedad Inflamatoria Intestinal Indicacin De Colectoma: ANTECEDENTES:Los pacientes con enfermedad inflamatoria intestinal tienen un mayor riesgo de cáncer colorrectal y se recomienda someterse a una mayor vigilancia en comparación con la población general. Actualmente, existe evidencia inadecuada para guiar el manejo de la displasia colónica descubierta durante la valoracion de pacientes con enfermedad inflamatoria intestinal.OBJETIVO:Determinar el riesgo de cáncer colorrectal en pacientes con colitis ulcerosa o enfermedad de Crohn con displasia en la colonoscopia.DISEÑO:Este fue un estudio retrospectivo.AJUSTE:Este estudio se llevó a cabo en un centro de referencia cuaternario de alto volumen con un programa de enfermedad inflamatoria intestinal.PACIENTES:Pacientes con diagnóstico de enfermedad inflamatoria intestinal con colonoscopia dentro de los 6 meses posteriores a la colectomía.PRINCIPALES MEDIDAS DE RESULTADO:Las principales medidas de resultado incluyeron el hallazgo de cáncer colorrectal en el momento de la colectomía.RESULTADOS:Hubo 621 pacientes: 233 con colitis ulcerosa y 388 con enfermedad de Crohn. De los pacientes con colitis ulcerosa, 25 tenían displasia de bajo grado en la colonoscopia y 1 (4%) tenía cáncer colorrectal en la colectomía. Se observó displasia de alto grado antes de la operación en 14 y cáncer colorrectal en 4 (29%) después de la colectomía. En comparación con la ausencia de displasia, la displasia de bajo grado no aumentó el riesgo de cáncer colorrectal (Odds Ratio 1,98, p = 0,47), pero la displasia de alto grado tuvo un mayor riesgo (OR 19,0, p <0,001) de cáncer colorrectal. Para los 7 pacientes con enfermedad de Crohn y displasia de bajo grado, se encontró cáncer colorrectal en 1 (14%) en la colectomía. Se observó displasia de alto grado antes de la operación en 4 pacientes con enfermedad de Crohn y cáncer colorrectal en 3 pacientes (75%) después de la colectomía. En comparación con la ausencia de displasia, la displasia de bajo grado no aumentó el riesgo de cáncer colorrectal (Odds Ratio 12.4, p = 0.88), pero la displasia de alto grado sí aumentó el riesgo de cáncer colorrectal (Odds Ratio 223.2, p <.001).LIMITACIONES:Este estudio estuvo limitado por su revisión retrospectiva.
Conclusin: Tanto en la colitis ulcerosa como en la enfermedad de Crohn, la displasia de bajo grado no se asoció con el cáncer colorrectal. La displasia de alto grado se asoció con un mayor riesgo de cáncer colorrectal en el momento de la colectomía. Si bien la vigilancia continua puede ser apropiada para la displasia de bajo grado, la displasia de alto grado requiere resección quirúrgica dada la alta probabilidad de cáncer colorrectal.

Background: Radiation segmentectomy (RS) is an alternative potential local curative treatment for selected colorectal liver metastases (CLMs) not amenable to ablation or limited resection.
Purpose: The aim of this study was to evaluate the dosimetric response of low volume CLMs to RS in heavily pretreated patients who are not candidates for resection or percutaneous ablation.
Patients And Methods: This single-center retrospective study evaluated CLMs patients treated with RS (prescribed tumor dose >190 Gy) from 2015 to 2023.
Introduction: Recently, a three-step endoscopic scale, known as the Diverticular Inflammation and Complication Assessment (DICA), was introduced to predict the course of diverticular disease (DD), yielding some promising outcomes. However, analyses were performed only for symptomatic individuals.
Objectives: The aim of our study was to prospectively evaluate the predictive value of DICA in asymptomatic individuals with no previous diagnosis of DD who underwent colorectal cancer screening colonoscopy.

Background: Minimally invasive surgery is associated with improved short-term outcomes and similar long-term oncologic outcomes for colorectal cancer patients compared with open surgery. Although the robotic approach has ergonomic and technical benefits, how it has impacted utilization of traditional laparoscopic surgery and minimally invasive surgery overall is unclear.
Objective: Describe trends in open, robotic, and laparoscopic approaches for colorectal cancer resections and examine factors associated with minimally invasive surgery.

Background: Despite the current diagnostic techniques and therapeutic methods for colorectal cancer (CRC), patients are often diagnosed at advanced stages of colorectal cancer with poor prognosis and distant metastasis. Recently, numerous investigations have highlighted the crucial role of lncRNAs in cancer development, progression, invasion, and metastasis. This study investigated less well-characterized genes in the colorectal cancer metastasis process using bioinformatics analysis and their confirmation by experimental methods.
