    Ultrasonic mucosal proctectomy removes rectal lining without perineal dissection, offering a less morbid alternative to abdominoperineal resection for specific rectal diseases.

    Area of Science:

    • Colorectal Surgery
    • Gastroenterology
    • Surgical Innovation

    Background:

    • Surgical treatment for familial polyposis coli and ulcerative colitis often necessitates rectal removal.
    • Abdominoperineal resection, a common method, is associated with significant patient morbidity.

    Purpose of the Study:

    • To evaluate the efficacy and safety of ultrasonic mucosal proctectomy as an alternative surgical technique.
    • To assess the potential for reduced morbidity compared to traditional abdominoperineal resection.

    Main Methods:

    • Ten adult mongrel dogs underwent ultrasonic mucosal proctectomy and proximal rectal resection with end colostomy.
    • The rectal remnant was examined two months post-procedure after sacrifice.

    Main Results:

    Related Experiment Videos

    • The rectal remnant exhibited shrinkage and fibrous healing of the muscular wall, leading to lumen obliteration.
    • No mucosal regeneration was observed in the remaining rectal tissue.
    • The procedure successfully removed distal rectal mucosa while preserving the muscularis.

    Conclusions:

    • Ultrasonic mucosal proctectomy achieves similar outcomes to abdominoperineal resection without perineal dissection morbidity.
    • This technique may be a viable option for rectal removal in benign diseases where endorectal pull-through is not suitable.
