PURPOSE: Stapled hemorrhoidopexy is designed to replace the hemorrhoids into the anal canal by excising the redundant rectal mucosa above the anorectal ring, thus resulting in an intrarectal suture. Few studies have evaluated rectal function after this procedure. This prospective study was designed to use the electronic barostat to assess whether rectal motor and sensory functions change after stapled hemorrhoidopexy. METHODS: Ten patients (4 women, mean age, 46±9 years) with third-degree and fourth-degree hemorrhoids who underwent stapled hemorrhoidopexy were studied. One week before and six months after surgery, they underwent three different rectal distensions (pressure-controlled stepwise, volume-controlled stepwise, and ramp) controlled by an electronic barostat. RESULTS: Rectal distensibility was significantly lower after surgery during pressure stepwise (P=0.01), during volume stepwise (P=0.006), and during ramp distension (P=0.001). Volume thresholds for desire to defecate, urgency, and discomfort were significantly lower after surgery during all three distensions (P
