Background/Aims: Distinction is vague between severe constipation and postoperative ileus (POI) in terms of pathogenesis, clinical features, and treatment options. However, no data are available regarding their associations.
Methods: After retrospective review of data from patients who underwent orthopedic surgery during the first 6 months of 2011, a total of 612 patients were included. Severe constipation was defined as symptoms of constipation requiring treatment using at least 2 laxatives from different classes for at least 6 months. POI was defined as paralytic ileus lasting more than 3 days post-surgery and associated with 2 or more of the following: (1) nausea/vomiting, (2) inability to tolerate an oral diet over a 24-hour period, and (3) absence of flatus over a 24-hour period. The subjects were divided into non-POI and POI groups, and we compared patient-, surgery-, and pharmaceutical-related factors.
Results: Thirteen (2.1%) out of 612 experienced POI. In comparisons between the non-POI and POI groups, univariate analysis showed significant differences in the mean age (51.4 vs 71.6 years), mean body mass index (24.1 vs 21.8 kg/m2), severe constipation (5.8% vs 76.9%), co-morbidities (33.2% vs 84.6%), type of orthopedic surgery (spine/hip/limb: 19.4/11.0/65.6% vs 23.1/61.5/15.4%), and estimated blood loss (50 vs 300 mL). Multivariate logistic regression analysis, after adjustment for age, body mass index, co-morbidities, type of orthopedic surgery, and estimated blood loss, showed that severe constipation was an independent risk factor for POI (OR, 35.23; 95% CI, 7.72?160.82; P < 0.001).
Conclusions: Severe constipation is associated with POI after orthopedic surgery.
