Nomogram to Predict Postoperative Intra-abdominal Septic Complications After Bowel Resection and Primary Anastomosis
1Department of General Surgery, Jinling Hospital, Medical School of Nanjing University, Nanjing, China.
Background:
Postoperative intra-abdominal septic complications of Crohn's disease substantially increase the healthcare expenditure and prolong hospitalization.
Objective:
We aimed to develop and validate a prediction model for intra-abdominal septic complications after bowel resection and primary anastomosis for Crohn's disease.
Design:
This was a retrospective cohort study.
Settings:
This study was conducted in a tertiary center.
Patients:
Data of 949 Crohn's disease-related primary bowel resections and anastomosis from January 2011 to December 2017 were collected.
Main Outcome Measures:
Primary outcomes were prevalence of intra-abdominal septic complications.
Results:
Overall prevalence of intra-abdominal septic complications after Crohn's disease surgery was 11.6%. Predictors included preoperative C-reactive protein level ≥40 mg/L (OR = 3.545), preoperative glucocorticoids (OR = 1.829) and infliximab use (OR = 3.365), upper GI involvement (OR = 2.072), and hypoalbuminemia (albumin level <30 g/L, OR = 2.406). Preoperative exclusive enteral nutrition was a protector for postoperative septic complications (OR = 0.192) compared with partial enteral nutrition/parenteral nutrition/straight to surgery. A nomogram was computed to facilitate risk calculation; this had a predictive discrimination, measured as area under the receiver operating characteristic curve, of 0.823.
Limitations:
This model is generated from retrospective data. A major limitation of this model is the lack of external validation.
Conclusions:
A new model to predict postoperative intra-abdominal septic complications was developed, which may guide preoperative optimization and candidate selection for primary anastomosis after bowel resection for Crohn's disease.

NOMOGRAMA PARA PREDECIR COMPLICACIONES SéPTICAS INTRAABDOMINALES POSTOPERATORIAS DESPUéS DE RESECCIóN INTESTINAL Y ANASTOMOSIS PRIMARIA EN ENFERMEDAD DE CROHN: Las complicaciones sépticas intraabdominales postoperatorias en la enfermedad de Crohn aumentan sustancialmente los costos de atención médica y prolongan la hospitalización.Nuestro objetivo fue desarrollar y validar un modelo de predicción para las complicaciones sépticas intraabdominales después de resección intestinal y anastomosis primaria en enfermedad de Crohn.Este fue un estudio de cohorte retrospectivo.Este estudio se realizó en un centro de tercer nivel.Se recopilaron datos de 949 resecciones intestinales primarias con anastomosis por enfermedad de Crohn de enero de 2011 a diciembre de 2017.El resultado primario fue la prevalencia de complicaciones sépticas intraabdominales.La prevalencia general de complicaciones sépticas intraabdominales después de cirugía por enfermedad de Crohn fue 11.6%. Los predictores incluyeron un nivel preoperatorio de proteína C reactiva ≥ 40 mg / L (odds ratio = 3.545), glucocorticoides preoperatorios (odds ratio = 1.829) y uso de infliximab (odds ratio = 3.365), compromiso gastrointestinal superior (odds ratio = 2.072) e hipoalbuminemia (albúmina <30g / L, odds ratio = 2.406). La nutrición enteral exclusiva preoperatoria fue un protector para las complicaciones sépticas postoperatorias (odds ratio = 0.192, en comparación con la nutrición enteral parcial / nutrición parenteral / envío directo a cirugía. Se calculó un nomograma para facilitar el cálculo del riesgo; esto tuvo una discriminación predictiva, medida como área bajo la curva de la característica de operación del receptor, de 0.823.Este modelo se generó a partir de datos retrospectivos. Una limitación importante de este modelo es la falta de validación externa.Se desarrolló un nuevo modelo para predecir complicaciones sépticas intraabdominales postoperatorias, que puede guiar la optimización preoperatoria y la selección de candidatos para anastomosis primaria después de resección intestinal en enfermedad de Crohn.

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.
