Background:
Dialysis patients are at high risk for surgery, but their outcomes after splenectomy are unclear. We compared postoperative complications between dialysis and non-dialysis patients.
Methods:
Data were retrieved from the National Surgical Quality Improvement Program for this retrospective cohort. Adult patients undergoing elective splenectomy between 2005 and 2020 were included.
Results:
Among 10,339 included patients, 143(1.4%) were on chronic dialysis. Postoperative mortality was higher in dialysis vs. non-dialysis patients (9.1% vs. 1.8%). Dialysis patients were more likely to have 30-day major morbidity, infectious and non-infectious complications, reoperation, and prolonged hospital stay. On multivariable regression, dialysis dependence significantly increased odds of mortality, major morbidity, blood transfusion, prolonged length of stay, reoperation, and failure-to-rescue (FTR).
Conclusion:
Dialysis patients were at higher risk of postoperative morbidity following splenectomy. Additionally, the risk of FTR in this patient population is also significantly more compared to non-dialysis patients.

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
