A Retrospective Chart Review of Ostomy Pouching Systems in New Ileostomy Patients: A Sub-Analysis.

Background/Objectives: Ostomy creation surgery is a common intervention for patients with conditions such as colorectal cancer, ulcerative colitis, Crohn's disease, or acute events like trauma and gastrointestinal perforation. Individuals with an ileostomy face unique challenges when managing their new ostomies due to the liquid caustic nature of the effluent, increasing the likelihood of leakage and peristomal skin complications (PSCs). This sub-analysis evaluates the prevalence of leakage and PSCs in a cohort of individuals with a new ileostomy and examines the risk of leakage of different ostomy pouching systems and their impact on leakage and PSCs. Methods: This sub-analysis examined a cohort of 98 patients from a previously published retrospective chart review of stoma-creation surgeries at the University of Pittsburgh Medical Center. Data on pouching system selection, leakage, and PSCs were collected from electronic medical records and evaluated across 479 pouch changes. Two main barrier pouching systems were analyzed: elastic tapeless border (ETB) and ceramide-infused tape-border (CIB) barriers. Statistical analyses using generalized linear mixed models assessed the risk of leakage for each barrier type and controlled for significant differences in the sub-groups. Results: The prevalence of leakage in the ileostomy cohort was 19%, with the prevalence of leakage increasing over successive pouch changes. The ETB sub-group experienced a significantly lower risk of leakage (13.7%) compared to CIB (29.3%), reflecting a 53.2% lower risk of leakage with ETB (p = 0.03; OR 2.45). Conclusions: This sub-analysis of ileostomy patients confirms that ETB significantly reduces the risk of leakage in this more difficult to manage population compared to CIB, a clinically important consideration in PSC development and overall ostomy management. Evidence-based selection of ostomy barriers can improve patient outcomes, enhance quality of life, and reduce healthcare resource utilization.
