Background: Previous studies reported similar complication rates, including anastomotic leakage, after elective and emergency surgery for right-sided colon cancer. This led to the consensus that emergency resection with primary anastomosis is safe. However, recent evidence suggests higher complication rates after emergency surgery, indicating that alternative strategies, such as a bridge to surgery, may be more suitable.
Objective: To assess whether complication rates, particularly anastomotic leakage, are higher after emergency resections compared to elective resections in patients with right-sided colon cancer.
Design: A retrospective cohort study using data from the Dutch ColoRectal Audit from 2010 to 2019.
Settings: Nationwide data from hospitals across the Netherlands.
Patients: Patients who underwent resection for right-sided colon cancer (n = 5056 emergency resections matched 1:1 to elective resections using propensity score matching).
Main Outcome Measures: Incidence of anastomotic leakage, 90-day complication rates, and mortality rates after elective versus emergency surgery for right-sided colon cancer.
Results: After matching, no significant baseline differences remained. There was no significant difference in anastomotic leakage rates. However, the mortality rate was twice as high in the emergency group (9.4% vs 4.2%, p < 0.001), and the 90-day complication rate was also higher (41.7% vs 33.0%, p < 0.001).
Limitations: Minimal missing data were handled with multiple imputation. Although propensity score matching was used, bias from unknown confounders may persist. The emergency group included more high-risk patients, potentially influencing outcomes.
Conclusions: Emergency resections for right-sided colon cancer are associated with higher complication and mortality rates compared to elective surgery. A bridge-to-surgery approach could reduce these risks by converting emergency cases to elective procedures. Further research is needed to validate these findings. See Video Abstract.
Resultados Tras La Reseccin Electiva Frente A La Reseccin De Emergencia Para Cncer De Colon Del Lado Derecho Un Anlisis De Puntuacin De Propensin Coincidente: ANTECEDENTES:Estudios previos informaron tasas de complicaciones similares, incluida la fuga anastomótica, después de una cirugía electiva y de emergencia para el cáncer de colon del lado derecho. Esto llevó al consenso de que la resección de emergencia con anastomosis primaria es segura. Sin embargo, evidencia reciente sugiere tasas de complicaciones más altas después de la cirugía de emergencia, lo que indica que las estrategias alternativas, como un puente a la cirugía, pueden ser más adecuadas.OBJETIVO:Evaluar si las tasas de complicaciones, en particular la fuga anastomótica, son más altas después de las resecciones de emergencia en comparación con las resecciones electivas en pacientes con cáncer de colon del lado derecho.DISEÑO:Un estudio de cohorte retrospectivo que utiliza datos de la Dutch ColoRectal Audit de 2010 a 2019.ESCENARIO:Datos a nivel nacional de hospitales de los Países Bajos.PACIENTES:Pacientes que se sometieron a una resección por cáncer de colon del lado derecho (n = 5056 resecciones de emergencia emparejadas 1:1 con resecciones electivas mediante emparejamiento por puntaje de propensión).PRINCIPALES MEDIDAS DE VALORACIÓN:Incidencia de fuga anastomótica, tasas de complicaciones a los 90 días y tasas de mortalidad después de cirugía electiva versus cirugía de emergencia para cáncer de colon del lado derecho.RESULTADOS:Después del emparejamiento, no se mantuvieron diferencias significativas al inicio. No hubo diferencias significativas en las tasas de fuga anastomótica. Sin embargo, la tasa de mortalidad fue dos veces más alta en el grupo de emergencia (9,4% frente a 4,2%, p < 0,001) y la tasa de complicaciones a los 90 días también fue mayor (41,7% frente a 33,0%, p < 0,001).LIMITACIONES:Los datos faltantes mínimos se manejaron con imputación múltiple. Si bien se utilizó el emparejamiento por puntaje de propensión, puede persistir el sesgo de factores de confusión desconocidos. El grupo de emergencia incluyó más pacientes de alto riesgo, lo que potencialmente influyó en los resultados.CONCLUSIONES:Las resecciones de emergencia para cáncer de colon del lado derecho se asocian con mayores tasas de complicaciones y mortalidad en comparación con la cirugía electiva. Un enfoque de puente a la cirugia podría reducir estos riesgos al convertir los casos de urgencia en procedimientos electivos. Se necesitan más investigaciones para validar estos hallazgos.

Aim And Background: This study investigates the impact of D3 lymph node dissection extent on postoperative bowel function and nutritional status in patients undergoing radical surgery for right-sided colon cancer. Given that postoperative diarrhea can significantly affect the quality of life, we examined whether dissection boundaries influence these outcomes.
Methods: This was a prospective, randomized controlled trial conducted at a high-volume tertiary hospital.

Aim: The clinical characteristics of colonic diverticular perforation are poorly understood. We aimed to clarify the clinical characteristics of colonic diverticular perforation.
Methods: Patients who underwent surgery for colonic diverticular perforation from 2011 to 2021 were retrospectively evaluated.

Background: To compare doses deposited to the liver during right breast radiotherapy with static and dynamic radiotherapy techniques. The second aim was to introduce the liver load index (LLI), a novel index developed to estimate radiation exposure to the liver prior to treatment selection.
Materials And Methods: We prepared radiotherapy treatment plans for ten patients with right breast cancer.

Background And Aims: Data comparing the location of polyp yield in patients with positive stool tests can aid screening test selection. We conducted a cross sectional analysis of New Hampshire Colonoscopy Registry data to compare the location, left versus right side of the colon, of neoplasia detected on colonoscopy following a mt-sDNA+ or FIT+ test as compared to a reference group having colonoscopy without a stool test.
Methods: Our outcomes were advanced lesions (adenoma and/or serrated polyp, including cancer), advanced adenomas (AA), or advanced serrated polyps (ASP), stratified by location.

Introduction: Minimally invasive surgery offers significant advantages, including smaller incisions, reduced postoperative pain, and shorter recovery, especially in surgeries requiring access to multiple abdominal quadrants. However, robot-assisted resection of synchronous colorectal cancer (sCRC) remains technically challenging and unstandardized due to its rarity. Herein, we propose an N-shaped configuration of five-trocar placement for the simultaneous right- and left-sided colectomies with intracorporeal anastomosis.
