Sugar the Rim


    Sugar the Rim

    “Want to hear the funniest therapy that actually works?” – Dr. Ben Schnapp, former Chief Resident extraordinaire

    It was my first month of intern year, and I had just presented a patient with a recurrent rectal prolapse. Ben Schnapp, the senior resident, was delighted to show me what he said was the “the funniest therapy that actually works.” I followed Ben up to the cafeteria, where he rummage through the concessions grabbing several stray sugar packets. This was to become a teaching pearl that, despite my best efforts, I would never forget.

    How to reduce a rectal prolapse

    Step One: Apply gentle steady pressure with a gloved hand
    Step Two:  If you have difficulty reducing the prolapse, apply granulated sugar to the prolapse.
    Step Three: Let the sugar sit for 15 minutes and then reattempt the reduction. The sugar will absorb the extra water and cause the prolapse to shrink.
    Step Four: If “sugaring the rim” fails, the next step is surgical reduction – so call your consult and pass that baton!
    Pro Tip: Yes, you must use granulated sugar. A sugar substitute will not work! (Sorry, no Splenda!)

    Case reports suggest this method works about 50% of the time. That may seem small but if it saves someone a trip to the OR then it’s worth a try.
