Background:
Redo ileocolic resection for recurrent Crohn's disease is associated with increased technical complexity and higher complication rates compared to primary resection. Literature concerning redo surgery for recurrent Crohn's disease is scarce and it is controversial whether a redo is a risk factor for postoperative anastomotic leak.
Objective:
This study aimed to hypothesized that redo ileocolic resection for Crohn's disease is an independent risk factor for anastomotic leak.
Design:
Retrospective, case-control study from 1994 to 2019 with multivariate analysis and propensity score weighting.
Setting:
Quaternary, IBD-referral center.
Patients:
Adult patients aged >18 years were included in the study.
Interventions:
Primary or redo ileocolic resection with an anastomosis, with or without diverting ileostomy.
Main Outcome Measures:
Thirty-day anastomotic leak rate.
Results:
A total of 991 patients (56% primary and 44% redo ileocolic resections) were included. Patients who underwent redo resection were significantly older with more comorbidities, fewer medications, and less fistulizing disease compared to the primary group. On univariate analysis, patients who underwent redo resection had more overall complications (50.5% vs 36.2%, p < 0.001), and the cumulative number of prior ileocolic resections was significantly associated with increased risk for overall morbidity ( p < 0.001). There were 31 (3%) anastomotic leaks; leak rates did not differ between groups ( p = 0.60). Multivariable analysis indicated that extensive adhesiolysis ( p < 0.001), ileostomy omission ( p = 0.009), and intraoperative abscess/fistula ( p = 0.02) were independently associated with leaks but not redo resection ( p = 0.27). Patients with 0, 1, 2, or 3 of these risk factors had observed leak rates of 1.1%, 1.3%, 6.0%, and 11.6.% ( p = 0.03), respectively.
Limitations:
The limitations of this study were selection bias, referral bias, and single quaternary center.
Conclusions:
Compared to primary procedures, redo ileocolic resection for recurrent Crohn's disease is associated with increased overall morbidity but not anastomotic leak. See Video Abstract at http://links.lww.com/DCR/C132 .
La Reseccin Ileoclica Rehecha No Es Un Factor De Riesgo Independiente De Fuga Anastomtica En La Enfermedad De Crohn Recurrente:
ANTECEDENTES:La resección ileocólica para la enfermedad de Crohn recurrente se asocia con una mayor complejidad técnica y mayores tasas de complicaciones en comparación con la resección primaria. La literatura sobre la reintervención quirúrgica para la enfermedad de Crohn recurrente es escasa y es controvertido si una redo es un factor de riesgo para la fuga anastomótica posoperatoria.OBJETIVO:Tenemos la hipótesis de que rehacer la resección ileocólica para la enfermedad de Crohn es un factor de riesgo independiente para la fuga anastomótica.DISEÑO:Estudio retrospectivo de casos y controles de 1994 a 2019 con análisis multivariado y ponderación de puntuación de propensión.AJUSTE:Centro de referencia de enfermedad inflamatoria intestinal de cuarto nivel.PACIENTES:Pacientes adultos >18 años.INTERVENCIONES:Resección ileocólica primaria o rehecha con una anastomosis, con o sin derivación de ileostomía.PRINCIPALES MEDIDAS DE RESULTADO:Tasa de fuga anastomótica a los 30 días.RESULTADOS:Se incluyeron un total de 991 pacientes (56% resecciones primarias y 44% resecciones ileocólicas rehechas). Los pacientes de reintervención eran significativamente mayores con más comorbilidades, menos medicamentos y menos enfermedad fistulizante en comparación con el grupo primario. En el análisis univariado, los pacientes reoperados tuvieron más complicaciones generales (50,5% frente a 36,2%, p < 0,001) y el número acumulado de resecciones ileocólicas previas se asoció significativamente con un mayor riesgo de morbilidad general ( p < 0,001). Hubo 31 (3%) fugas anastomóticas; las tasas de fuga no difirieron entre los grupos ( p = 0,6). El análisis multivariado indicó que la adhesiolisis extensa ( p < 0,001), la omisión de ileostomía ( p = 0,009) y el absceso/fístula intraoperatorios ( p = 0,02) se asociaron de forma independiente con fugas, pero no con nueva resección ( p = 0,27). Los pacientes con 0, 1, 2 o 3 de estos factores de riesgo observaron tasas de fuga del 1,1%, 1,3%, 6,0% y 11,6% ( p = 0,03), respectivamente.LIMITACIONES:Sesgo de selección, Sesgo de referencia, un centro de cuarto nivelCONCLUSIÓN:En comparación con los procedimientos primarios, la resección ileocólica para la enfermedad de Crohn recurrente se asocia con una mayor morbilidad general, pero no con una fuga anastomótica.

01:27Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
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...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
