Recurrence After Operative Treatment of Adhesive Small-Bowel Obstruction
Postoperative adhesions are a common cause of small-bowel obstruction, and up to 53% of patients operated on for adhesive small-bowel obstruction (ASBO) experience recurrence. The primary aim of this study was to identify predictors for recurrence of ASBO.
We reviewed medical records including operation descriptions from patients who underwent emergency surgery due to ASBO at our institution between 2004 and 2013. Information on the peri- and postoperative periods, including conservatively and surgically treated recurrent ASBO, were obtained from medical records.
In total, 478 patients were included in the study. Of these, 58 (12.1%) patients experienced recurrence of ASBO during median 2.2 years follow-up. Female gender (hazard ratio [HR] 2.00, P = 0.023), multiple/matted adhesions (HR 1.72, P = 0.046), and fascial dehiscence (HR 3.26, P = 0.009) were associated with increased risk of recurrence. Conversely, intestinal resection decreased the risk of recurrence (HR 0.47, P = 0.036).
The overall recurrence rate after surgically treated ASBO was 12.1%, and the risk of recurrence was persistent several years after index operation. Factors associated with an increased risk were female gender, multiple/matted adhesions, and fascial dehiscence.
