Conversion of Failed J Pouch to Kock Pouch: Indications, Contraindications and Outcomes

Abstract

BACKGROUND: The ileal pouch-anal anastomosis has been successful in restoring intestinal continuity and preserving continence in the majority of patients requiring a proctocolectomy. However, a subset of individuals experience significant complications that might result in pouch failure. The conversion of the J pouch to a continent ileostomy pouch represents a significant surgical procedure. In this article, we discuss the indications and contraindications, present the technical principles applied for the conversion, and describe the outcomes of such conversion in the literature. OBJECTIVE: The main objective during the conversion of the J pouch to a continent ileostomy is the creation of a sufficiently sized reservoir with a high-quality valve mechanism while preserving as much small bowel as possible. CONCLUSIONS: The conversion of the J pouch to a continent ileostomy represents a significant surgical procedure. When performed in centers of expertise, it can be a good option for patients who otherwise will require an end ileostomy. Indications for conversion include most cases of J pouch failure, with few important exceptions. See Video.
