PROSPER trial: A comparison of treatments for rectal prolapse

One discussion this week involved the PROSPER trial of treatment for rectal prolapse.

Summary: The PROSPER randomised control trial is a pragmatic, factorial (2 × 2) design trial in which 293 patients were randomised between abdominal and perineal surgery (i) (n=49), suture vs resection rectopexy for those receiving an abdominal procedure (ii) (n=78), or Altemeier’s vs Delorme’s for those receiving a perineal procedure (iii) (n=213). Primary outcome measures were recurrence of the prolapse, incontinence, bowel function and quality of life scores measured up to 3 years.

Recurrence rates were not significant in any comparisons:

  • abdominal vs perineal surgery: 20% vs 26%
  • suture vs resection rectopexy: 13% vs 26%
  • Altemeier’s vs Delorme’s: 24% vs 31%

It was noted that substantial improvements from baseline in quality of life following all procedures. Additionally, Vaizey, bowel thermometer and EQ-5D scores were not significantly different in any of the comparisons (Senapati et al, 2013).
