Modifiable Analgesia-/Anesthesia-Related Factors and Risk of Severe Gastrointestinal Complications After Lower Extremity Total Joint Arthroplasty: A Nationwide Analysis.

We studied the epidemiology of severe GI complications after THA/TKA and associations with anesthesia- and/or analgesia-related factors.
