Gastrointestinal Complications Following Total Joint Arthroplasty Are Rare but Have Severe Consequences

Abstract Background Gastrointestinal (GI) complications following total joint arthroplasty (TJA) are rare, but can result in substantial morbidity and mortality, especially when intervention is required. The purpose of this study is to identify modifiable risk factors for the development of GI complications and determine their impact on short-term outcomes following TJA. Methods We queried patients who underwent primary TJA at a single academic center from 2009 through 2018 by 19 surgeons and collected data on demographics, comorbidities, operative and perioperative details, and short-term outcomes. Patients who suffered at least one GI complication during the same hospitalization as their TJA were identified. The type of GI complication and intervention performed, if necessary, was recorded. Variables that independently affected the risk of GI complication were identified. Multivariate regression was performed to determine the effect suffering a GI complication had on outcomes. Results Of 17,402 patients, 106 (0.6%) suffered a GI complication. Constipation/obstruction, followed by diarrhea/malabsorption, hemorrhage, and Clostridium difficile were the most commonly reported complications. Patients suffering a GI complication were significantly older (68.5 vs 63.7, p Conclusion Patients suffering a GI complication following TJA require longer hospital stays and greater post-acute care resources and have substantially higher risk of mortality.
