title: [Complications after procedure for prolapse and hemorrhoids for circular hemorrhoids].
abstract: OBJECTIVE
  To investigate the perioperative and postoperative  long-term complications of procedure for prolapse and hemorrhoids(PPH) for the treatment of circular internal hemorrhoids and circular mixed hemorrhoids.
  
  
  METHODS
  A retrospective study was performed in 2152 patients with circular internal hemorrhoids and circular mixed hemorrhoids eligible for PPH from January 2002 to December 2011. The perioperative and postoperative long-term complications were recorded and assessed.
  
  
  RESULTS
  The median length of follow-up was 73 months. Perioperative complications and adverse events were reported including acute urinary retention(n=360, 16.7%) which was managed by temporary cathether indwelling, anastomotic bleeding(n=45, 2.1%) managed by surgical or endoscopic procedures, chronic anoperineal sustained pain(n=30, 1.4%) managed by local treatment or stapler removal, and thrombosed external hemorrhoid(n=28, 1.2%) managed by conservative treatment or resection. Long-term postoperative complications were reported including mild fecal incontinence(n=112, 6.3%), postoperative recurrence(n=82, 4.6%), anal distention and defecatory urgency(n=50, 2.8%), anastomotic stenosis(n=4, 0.2%). Postoperative recurrence developed in 82 patients(4.6%), 28 of whom were managed by repeat PPH and 54 by conservative treatment.
  
  
  CONCLUSIONS
  PPH appears to be a safe technique for patients with circular internal hemorrhoids and circular mixed hemorrhoids.
