Abstract

Background: Factors associated with postoperative ileus and increased resource utilization for patients who undergo operative intervention for small-bowel obstruction are not extensively studied. We evaluated the association between total duration of preoperative symptoms and postoperative outcomes in this population. Materials and methods: We performed a retrospective review of patients who underwent surgery for small-bowel obstruction (2013-2016). Clinical data were recorded. Total duration of preoperative symptoms included all symptoms before operation, including those before presentation. Primary endpoint was time to tolerance of diet. Secondary endpoints included length of stay, total parenteral nutrition use, and intensive care unit admission. Association between variables and outcomes was analyzed using univariable analysis, multivariable Poisson modeling, and t-test to compare groups. Results: Sixty-seven patients were included. On presentation, the median duration of symptoms before hospitalization was 2 d (range 0-18 d). Total duration of preoperative symptoms was associated with time to tolerance of diet on univariable analysis (Pearson's moment correlation: 0.28, 95% confidence interval: 0.028-0.5, P = 0.03). On multivariable analysis, ascites was correlated with time to tolerance of diet (P < 0.01), but total duration of preoperative symptoms (P = 0.07) was not. Length of stay (Pearson's correlation: 0.24, 95% confidence interval: −0.02 to 0.47, P = 0.07) was not statistically different in patients with longer preoperative symptoms. Symptom duration was not statistically associated with intensive care unit (P = 0.18) or total parenteral nutrition (P = 0.3) utilization. Conclusions: Our findings demonstrate that preoperative ascites correlated with increased time to tolerance of diet, and duration of preoperative symptoms may be related to postoperative ileus.
