Colostomy formation in a peritoneal dialysis patient

This case report discusses the complex management of a 46-year-old man with poorly controlled type 1 diabetes mellitus, stage 5 chronic kidney disease, and severe neuropathic complications, which led to bilateral leg amputations. The patient experienced persistent diarrhea due to diabetic neuropathy, significantly impairing his daily functioning. Despite transitioning from hemodialysis to peritoneal dialysis, the diarrhea persisted. A colostomy was subsequently performed, which, although it did not completely resolve the diarrhea, allowed for better control, improving the patient's self-care and independence. Notably, the catheter exit site was maintained on the opposite side of the abdomen. Despite initial concerns about the feasibility of peritoneal dialysis (PD) in patients with stomas, including the challenges of creating a stoma in patients with an existing PD catheter, this case demonstrates the successful continuation of PD following a colostomy. Traditionally, intestinal stomas have been viewed as a relative contraindication to PD due to risks such as leakage and infection. However, current guidelines recommend using extended catheters with a presternal exit site to minimize these risks. The patient's quality of life improved significantly after the colostomy, with no major complications observed during follow-up. This report underscores the importance of tailoring treatment to individual patient needs, balancing risks with potential well-being benefits, and highlights the necessity of interdisciplinary collaboration and adherence to best practices. Given the limited literature on PD in patients with intestinal stomas, this case contributes valuable clinical insights for future management.
