Key result
Not being on a full diet by post-operative day 2 significantly increased the risk of severe post-operative ileus in hip and knee patients (OR 7.96) and spine patients (OR 11.70).
Why the study?
Post-operative ileus is common and can cause significant morbidity, but the incidence of and risk factors for severe post-operative ileus after elective orthopedic surgery remained to be identified.
Case-Control (n=231)
No
Odds Ratio: 7.96 (95% CI 1.17–53.94)
p-value: p=0.034
Delayed progression to a full diet by post-operative day 2 and longer operative times are significant risk factors for severe post-operative ileus after elective orthopedic surgery.

Delayed diet advancement by POD 2 signals elevated SPOI risk after orthopedic procedures; hypothesis-generating and requires prospective validation before changing practice.
Mandl et al. (2019) conducted a case-control in Severe post-operative ileus (SPOI) after elective orthopedic surgery (n=231). Not being on a full diet by post-operative day 2 vs. Being on a full diet by post-operative day 2 was evaluated on Severe post-operative ileus (SPOI) in hip and knee surgery patients (OR 7.96, 95% CI 1.17-53.94, p=0.034). Not being on a full diet by post-operative day 2 significantly increased the risk of severe post-operative ileus in hip and knee patients (OR 7.96) and spine patients (OR 11.70).
