    The novel four loop (W) reservoir offers improved functional outcomes and avoids catheterization compared to older methods. This surgical technique demonstrates high patient continence and spontaneous bowel function.

    Area of Science:

    • Colorectal Surgery
    • Surgical Innovation
    • Patient Outcomes

    Background:

    • The J reservoir and S reservoir have limitations, including functional deficits and the frequent need for catheterization.
    • A new surgical approach is needed to enhance functional results and patient convenience.

    Purpose of the Study:

    • To evaluate the efficacy and functional outcomes of the four loop (W) reservoir.
    • To compare the W reservoir to existing J and S reservoir techniques.

    Main Methods:

    • A cohort of 64 patients underwent the four loop (W) reservoir procedure.
    • Surgical construction complexity and postoperative outcomes were assessed.
    • Functional outcomes, including defecation frequency, continence, and medication use, were evaluated over a mean follow-up of 18.6 months.

    Main Results:

    • The W reservoir procedure showed no mortality and a mean hospital stay of 24 days.
    • 92% of patients achieved normal continence, with only 8% experiencing minor leakage.
    • All patients achieved spontaneous defecation, with 14% requiring nighttime evacuation and 20% needing antidiarrheal medication.

    Conclusions:

    • The four loop (W) reservoir is a safe and effective surgical option for fecal diversion.
    • This technique improves functional results and patient continence while avoiding catheterization requirements.
    • The W reservoir represents a significant advancement in surgical management for patients requiring fecal diversion.
