RESUMEN
PURPOSE: Pain and reduced quality of life (QoL) are major subjects of interest after surgery for hemorrhoids. The aim of this study was to find predictive parameters for postoperative pain and QoL after hemorrhoidectomy. METHODS: This is a follow-up analysis of data derived from a multicenter randomized controlled trial including 770 patients, which examines the usefulness of tamponade after hemorrhoidectomy. Different pre-, intra-, and postoperative parameters were correlated with pain level assessed by NRS and QoL by the EuroQuol. RESULTS: At univariate analysis, relevant (NRS > 5/10 pts.) early pain within 48 h after surgery was associated with young age (≤ 40 years, p = 0.0072), use of a tamponade (p < 0.0001), relevant preoperative pain (p = 0.0017), pudendal block (p < 0.0001), and duration of surgery (p = 0.0149). At multivariate analysis, not using a pudendal block (OR 2.64), younger age (OR 1.55), use of a tamponade (OR 1.70), and relevant preoperative pain (OR 1.56) were significantly associated with relevant early postoperative pain. Relevant pain on day 7 was significantly associated only with relevant early pain (OR 3.13, p < 0.001). QoL overall remained at the same level. However, n = 229 (33%) patients presented an improvement of QoL and n = 245 (36%) an aggravation. Improvement was associated with a reduction of pain levels after surgery (p < 0.0001) and analgesia with opioids (p < 0.0001). CONCLUSION: Early relevant pain affects younger patients but can be prevented by avoiding tamponades and using a pudendal block. Relevant pain after 1 week is associated only with early pain. Relief in preexisting pain and opioids improve QoL. TRIAL REGISTRATION: DRKS00011590 12 April 2017.

BACKGROUND: Symptomatic haemorrhoids are a common anorectal disorder. The aim of the study was to investigate whether the omission of tamponade dressings after haemorrhoidectomy reduces postoperative pain without increasing the risk of severe bleeding. METHOD: This was an open-label, randomized clinical trial conducted at 14 German hospitals. All patients with third- or fourth-degree haemorrhoids undergoing haemorrhoidectomy were considered eligible for selection in the intervention (no dressing) or control group (tamponade applied). Two co-primary outcomes were analysed by testing hierarchically ordered hypotheses. First, maximum pain intensity within 48â h after surgery was compared between the groups (superiority). This was followed by an analysis of severe bleeding complications, defined as any bleeding requiring surgical re-intervention within 7 days (non-inferiority). Secondary outcomes included health-related quality of life, patient satisfaction, haemoglobin levels, and adverse events. RESULTS: Out of 950 patients screened, 754 were randomized and 725 received intervention (366 patients in the intervention and 359 patients in the control group). In the group with tamponade dressings, median pain intensity on the 0 to 10 scale was 6 (interquartile range (i.q.r.) 4-7). Patients without tamponade dressings reported significantly less pain (median 5 (i.q.r. 3-7), P < 0.001). In each group, five patients (1.4 per cent) experienced severe bleeding. The absolute difference for the severe bleeding rate was -0.03 per cent with the 90 per cent confidence interval ranging from -1.47 per cent to +1.41 per cent, in line with the non-inferiority aim. No significant between-group difference was found for secondary outcomes. CONCLUSIONS: The practice of inserting tamponade dressings after haemorrhoidectomy correlates with increased postoperative pain and does not provide benefits in terms of reduced postoperative bleeding.
