Background:
The recent advent of the Kono-S anastomosis has raised the question of the impact of anastomotic configuration on recurrence following ileocecectomy for Crohn's disease. Determining whether there is a superior configuration is an opportunity for improvement in optimization in surgical care for Crohn's disease patients. At the University of Chicago, we perform a variety of anastomotic configurations, including side-to-side, end-to-end, end-to-side, side-to-end, and Kono-S.
Objective:
Determine whether there is a difference in recurrence between anastomotic configurations following ileocecectomy for Crohn's disease at a high-volume IBD center.
Design:
Retrospective medical record review.
Setting:
The University of Chicago Medical Center.
Patients:
Two hundred thirty-nine patients who underwent an ileocecectomy for Crohn's disease from January 1, 2018, through December 31, 2022.
Main Outcome Measures:
Endoscopic recurrence rate for each anastomotic configuration.
Results:
Two hundred thirty-nine patients with Crohn's disease who underwent ileocecectomy were included. The anastomotic configurations were similar in terms of patient characteristics. The end-to-side anastomoses were associated with lower blood loss and shorter OR times. On multivariable analysis, elective surgery and end-to-side anastomotic configurations were associated with lower recurrence of Crohn's disease at an average follow-up of 32 months.
Limitations:
The study is retrospective in nature and was conducted at a single institution.
Conclusions:
End-to-side anastomosis configuration is a safe, technically easy-to-perform reconstruction method that may reduce the rate of disease recurrence. See Video Abstract .
La Anastomosis Ileoclica Trminolateral Tras La Ileocecectoma Por Enfermedad De Crohn Es Una Opcin Segura Con Baja Tasa De Recurrencia:
ANTECEDENTES:La reciente aparición de la anastomosis Kono-S ha planteado la cuestión del impacto de la configuración anastomótica en la recurrencia tras la ileocecectomía por enfermedad de Crohn. Determinar si existe una configuración superior representa una oportunidad para optimizar la atención quirúrgica de los pacientes con enfermedad de Crohn. En la Universidad de Chicago, realizamos diversas configuraciones anastomóticas, incluyendo latero-lateral, término-terminal, término-lateral, latero-terminal y Kono-S.OBJETIVO:Determinar si existe una diferencia en la recurrencia entre las distintas configuraciones anastomóticas tras la ileocecectomía por enfermedad de Crohn en un centro especializado en EII de alto volumen.DISEÑO:Revisión retrospectiva de historias clínicas.ÁMBITO:Centro Médico de la Universidad de Chicago.PACIENTES:Doscientos treinta y nueve pacientes sometidos a ileocecectomía por enfermedad de Crohn entre el 1 de enero de 2018 y el 31 de diciembre de 2022.PRINCIPALES MEDIDAS DE RESULTADO:Tasa de recurrencia endoscópica para cada configuración anastomótica.RESULTADOS:Se incluyeron 239 pacientes con enfermedad de Crohn sometidos a ileocecectomía. Las configuraciones anastomóticas fueron similares en cuanto a las características de los pacientes. Las anastomosis término-laterales se asociaron con menor pérdida de sangre y tiempos quirúrgicos más cortos. En el análisis multivariado, la cirugía electiva y la configuración anastomótica término-lateral se asociaron con una menor recurrencia de la enfermedad de Crohn con un seguimiento promedio de 32 meses.LIMITACIONES:El estudio es retrospectivo y se realizó en una sola institución.CONCLUSIONES:La configuración de anastomosis término-lateral es un método de reconstrucción seguro y técnicamente fácil de realizar que puede reducir la tasa de recurrencia de la enfermedad.

01:30Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by transmural...
