title: Rectal distensibility and symptoms after stapled and Milligan-Morgan operation for hemorrhoids.
abstract: BACKGROUND
  In a previous uncontrolled study, a reduction of rectal distensibility and volume thresholds for sensations have been related to the occurrence of fecal urgency and/or increased stool frequency after stapled hemorrhoidopexy.
  
  
  OBJECTIVE
  The aim of this study was to compare rectal symptoms and sensory-motor function after stapled hemorrhoidopexy and Milligan-Morgan hemorrhoidectomy.
  
  
  METHODS
  The clinical records of 12 (four women) and ten patients (four women) with third- and fourth-degree hemorrhoids, respectively, who underwent stapled hemorrhoidopexy or Milligan-Morgan's hemorrhoidectomy, were evaluated. One week before and 6 months after surgery, rectal motor and sensory response to distension was assessed by an electronic barostat, and bowel and rectal symptoms were recorded by means of a 7-day diary and Bristol Index scale and psychological symptoms with SCL-90 questionnaire.
  
  
  RESULTS
  Rectal distensibility and volume thresholds for sensations were significantly lower after surgery (P < 0.02) in the stapled group. Increased stool frequency and/or fecal urgency arose in 41% of patients in the stapled group and associated with altered rectal distensibility. No difference within and between groups could be demonstrated in SCL-90 score.
  
  
  CONCLUSIONS
  Rectal distensibility and volume thresholds for sensations decrease after stapled hemorrhoidopexy. Altered rectal distensibility was associated with rectal urgency and/or increased stool frequency.
