Background: There is no standard timing for switching to surgical management for children with adhesive small bowel obstruction (ASBO) who initially receive conservative treatment. We hypothesized that an increased gastrointestinal drainage volume may indicate the need for surgical intervention.
Methods: The study population included 150 episodes in the patients less than 20 years of age who received treatment for ASBO in our department from January 2008 to August 2019. Patients were divided into two groups: the successful conservative treatment group (CT) and the eventual surgical treatment group (ST). Following the analysis of all episodes (Study 1), we limited our analysis to only first ASBO episodes (Study 2). We retrospectively reviewed their medical records.
Results: There were statistically significant differences in the volume on the 2nd day in both Study 1 (9.1 ml/kg vs. 18.7 ml/kg; p < 0.01) and study 2 (8.1 ml/kg vs. 19.7 ml/kg; p < 0.01). The cut-off value was the same for both Study 1 and Study 2 (11.7 ml/kg).
Conclusions: The gastrointestinal drainage volume on the 2nd day in ST was significantly larger than that in CT. Accordingly, we considered that the drainage volume may predict eventual surgical intervention for children with ASBO who initially receive conservative treatment.
Level of evidence: Level IV.
