A Practical Predictive Index for Intra-abdominal Septic Complications After Primary Anastomosis for Crohn's Disease: Change in C-Reactive Protein Level Before Surgery.

Abstract

BACKGROUND:

Postoperative intra-abdominal septic complications are difficult to manage in Crohn's disease, which makes prevention especially important.

OBJECTIVE:

The purpose of this study was to examine the risk factors for intra-abdominal septic complications after primary anastomosis for Crohn's disease and to seek a practical predictive index for intra-abdominal septic complications.

DESIGN:

This was a retrospective study.

SETTINGS:

The study was conducted in a tertiary referral hospital.

PATIENTS:

Based on a computerized database of 344 patients with Crohn's disease who underwent primary anastomosis between 2004 and 2013, the patients were placed into an intra-abdominal septic complications group and a group without intra-abdominal septic complications.

MAIN OUTCOME MEASURES:

Univariate and multivariate analyses were performed to identify risk factors, and the predictive accuracy of possible predictors was assessed using receiver operating characteristic curves.

RESULTS:

Overall, 39 patients (11.34%) developed intra-abdominal septic complications. Preoperative C-reactive protein level >10 mg/L was found to be an independent risk factor (p < 0.01) for intra-abdominal septic complications. For prediction of intra-abdominal septic complications, receiver operating characteristic curve analysis showed that a C-reactive protein cutoff of 14.50 mg/L provided negative and positive predictive values of 96.84% and 34.07%. In addition, the change in C-reactive protein levels over the 2 weeks before surgery was greater in the intra-abdominal septic complications group than the group with no intra-abdominal septic complications (p < 0.01), and the directions of change were opposite, upward in the former and downward in the latter. Apart from being a risk factor for intra-abdominal septic complications (p < 0.01), receiver operating characteristic curve analysis showed that the change in C-reactive protein levels before surgery had a negative predictive value for intra-abdominal septic complications of 98.66% and a positive predictive value of 76.09%.

LIMITATIONS:

This was a retrospective study.

CONCLUSIONS:

Changes in C-reactive protein before surgical treatment of Crohn's disease could serve as a practical predictive index for postoperative intra-abdominal septic complications.
