Incidence and Risk Factors of Parastomal Bulging in Patients With Ileostomy or Colostomy
Incidence and Risk Factors of Parastomal Bulging in Patients With Ileostomy or Colostomy
The purpose of this study is to use routinely-collected health data from registers to examine
 the incidence of parastomal bulging (PB) at different time points in the first year after
 surgery for ileostomy or colostomy. Additionally, the purpose is to investigate risk factors
 for development of PB.
Parastomal bulging (PB) in patients with ileostomy and colostomy in the Capital Region of
 Denmark up to one year after surgery is the primary outcome in this study. The investigators
 will use a register-based study design to evaluate routinely-collected health data from the
 Danish Stoma Database Capital Region (DSDCR). Incidence of PB one year post surgery and at
 different points of follow-up during the first year will be investigated using survival
 analysis. Potential risk factors will be investigated controlling for potential confounders.
 In order to include relevant variables on lifestyle, comorbidity, and physical status, data
 from the DSDCR will be linked to data from the Danish Anaesthesia Database.
Inclusion Criteria:

 -  Subject is registered in the Danish Stoma Database Capital Region

 -  Is registered as having either ileostomy, jejunostomy, sigmoidostomy, or
 transversostomy
