Factors Predicting Surgical Treatment in Patients with Adhesive Small Bowel Obstruction: Retrospective Single-centre Study.

Abstract

To investigate the factors which predict treatment strategy in patients with adhesive small bowel obstruction. Descriptive study. General Surgery Clinic, Marmara University Medical Faculty, Istanbul, Turkey, between January 2016 and December 2020. Data of the patients with adhesive small bowel obstruction (ASBO) was retrospectively collected. The demographic characteristics and laboratory findings were evaluated. Patients, who underwent conservative treatment and surgical intervention, were compared. Differences between the two groups in terms of demographic characteristics, prognostic nutritional index (PNI) scores, and neutrophil (NEU)-to-lymphocyte (LYM) ratio (NLR), were evaluated. One-hundred thirty-seven patients were included in the study. Seventy-four (54%) of the patients had conservative treatment. There was no statistically significant difference between the surgical and conservative treatment groups according to the age, gender, and ASA score (p=0.77, 0.21 and 0.95 respectively). The patients with congenital aetiology and low PNI scores were in significantly higher numbers among the surgical treatment group (p <0.001 and p=0.004, respectively). In patients, who underwent surgery, the resection rate was found significantly higher in older age (63 vs. 52, p=0.01). Patients with low PNI scores and congenital adhesive small bowel obstruction undergo operative treatment more frequently than conservative treatment. Future studies focusing on diagnostic scores to predict early surgery in ASBO patients may include these variables. Adhesive small bowel obstruction, PNI, Treatment strategy, Surgery.
