title: Partial stapled hemorrhoidopexy versus circular stapled hemorrhoidopexy for grade III-IV prolapsing hemorrhoids: a two-year prospective controlled study.
abstract: BACKGROUND
  Circular stapled hemorrhoidopexy (CSH) is an effective technique for treating prolapsing hemorrhoids; but urgency and anal stenosis are common postoperative complications. The aim of this study was to assess the efficacy and postoperative outcomes of partial stapled hemorrhoidopexy (PSH), compared with CSH.
  
  
  METHODS
  Seventy-two consecutive patients with grade III and IV hemorrhoids who met the inclusion/exclusion criteria were divided in a non-randomized manner to undergo either PSH (n = 34) or CSH (n = 38). Intraoperative and postoperative parameters in both groups were collected and compared.
  
  
  RESULTS
  The postoperative visual analog score for pain at first defecation was significantly lower in the PSH group than that in the CSH group (P = 0.001). Fewer patients in the PSH group experienced postoperative urgency, compared with those in the CSH group at 12 h, 1 day, and 7 days after surgery (P = 0.025, P = 0.019, and P = 0.043, respectively). Gas incontinence occurred in 3 patients (7.9%) in the CSH group, but in none of patients in the PSH group (P = 0.242). Postoperative anal stenosis developed in one patient (2.6%) in the CSH group, but in none of the patients in the PSH group (P = 1.0). The 2-year recurrence rate was 2.9 and 5.3%, respectively, in the PSH and CSH groups (P = 1.0).
  
  
  CONCLUSIONS
  The 2-year recurrence rate is similar in patients with grade III-IV hemorrhoids treated with PSH or CSH. However, PSH is associated with less postoperative pain, fewer episodes of urgency, and no anal incontinence or anal stenosis.
