Comparison of mean pain score using topical and oral metronidazole in post milligan morgan hemorrhoidectomy patient; A randomized controlled trial

Topical metronidazole after haemorrhoidectomy to reduce postoperative pain: a systematic review

Excisional haemorrhoidectomy is the gold standard for operating haemorrhoids, but it is accompanied by a significant problem: postoperative pain. Several strategies have been adopted to minimize this condition. Oral metronidazole has been proven to reduce postoperative pain but with some complications. This systematic review was conducted to investigate the effects and general efficacy of topical metronidazole administration and to evaluate its potential superiority over the oral formula. A systematic review of the literature was carried out. Randomized controlled trials published until September 2023 on PubMed, Central, and Web of Science were considered. The primary outcome considered was postoperative pain, which was evaluated using visual analogue scores. The secondary outcomes were analgesic use, return to work, and complications. Six randomized controlled trials were included, with a total of 536 patients. Topical metronidazole was compared with placebo in two studies, with oral formula in three studies, and with placebo and oral administration in one study. Topical metronidazole was found to be effective for treating postoperative pain when compared to a placebo but had no significant advantage over the oral formula. No complications were reported in the studies. Topical and oral metronidazole are effective solutions for postoperative pain after excisional haemorrhoidectomy. No superiority was demonstrated based on the route of administration, and complications were marginal for both formulas. Further studies are required to determine the best metronidazole solution.

Milligan-Morgan hemorrhoidectomy combined with non-doppler hemorrhoidal artery ligation for the treatment of grade III/IV hemorrhoids: a single centre retrospective study

BACKGROUND

Milligan-Morgan hemorrhoidectomy (MMH) is the most widely used surgical procedure because of its precise curative effect, but it has the disadvantages such as obvious postoperative pain and bleeding. To retrospectively evaluate the efficacy and safety of MMH combined with non-Doppler hemorrhoidal artery ligation (MMH + ND-HAL) for the treatment of grade III/IV hemorrhoids.

METHODS

We conducted a retrospective analysis of 115 patients with grade III/IV hemorrhoids, 53 patients had received MMH + ND-HAL, and the remaining 62 patients received MMH. We collected and compared demographic and clinical characteristics of both groups, including intraoperative blood loss, postoperative visual analog scale (VAS) for pain, analgesic consumption, postoperative bleeding, perianal incision edema, urinary retention, anal stenosis, anal incontinence incidence, recurrence rate (prolapse or bleeding), and patient satisfaction.

RESULTS

The VAS pain score of the first postoperative defecation and at the postoperative 12 h, 1 day, 2 days, 3 days, and 7 days, as well as the total analgesic consumption within 7 days, for the MMH + ND-HAL group were lower than those for the MMH group (P < 0.05). The intraoperative blood loss, the incidence of postoperative bleeding, perianal incision edema, and urinary retention in the MMH + ND-HAL group was lower than that in the MMH group (P < 0.05). No anal stenosis or anal incontinence occurred in either group. At follow-up by telephone or outpatient 12 months after surgery, the recurrence rate (prolapse or bleeding) was lower in the MMH + ND-HAL group than in the MMH group (P < 0.05), and satisfaction was higher in the MMH + ND-HAL group than in the MMH group (P < 0.05).

CONCLUSIONS

MMH + ND-HAL was a satisfactory surgical modality for treating III/IV hemorrhoids.

PROSPECT guideline for haemorrhoid surgery: A systematic review and procedure-specific postoperative pain management recommendations

BACKGROUND

Haemorrhoidectomy is associated with moderate-to-severe postoperative pain.

OBJECTIVE

The aim of this systematic review was to assess the available literature and update previous PROSPECT (procedure specific postoperative pain management) recommendations for optimal pain management after haemorrhoidectomy.

DESIGN AND ELIGIBILITY CRITERIA

A systematic review utilising PROSPECT methodology was undertaken.

DATA SOURCES

Randomised controlled trials published in the English language from January 1, 2016 to February 2, 2022 assessing postoperative pain using analgesic, anaesthetic, and surgical interventions were identified from MEDLINE, EMBASE and Cochrane Database.

RESULTS

Of the 371 randomized controlled trials (RCTs) identified, 84 RCTs and 19 systematic reviews, meta-analyses met our inclusion criteria (103 publications). Interventions that improved postoperative pain relief included: paracetamol and nonsteroidal anti-inflammatory drugs or cyclo-oxygenase-2 selective inhibitors, systemic steroids, pudendal nerve block, topical metronidazole, topical diltiazem, topical sucralfate or topical glyceryl trinitrate, and intramuscular injection of botulinum toxin.

DISCUSSION

This review has updated the previous recommendations written by our group. Important changes are abandoning oral metronidazole and recommending topical metronidazole, topical diltiazem, topical sucralfate, topical glyceryl trinitrate. Botulinum toxin can also be administered. Contemporary publications confirm the analgesic effect of bilateral pudendal nerve block but invalidate recommendations on perianal infiltration. The choice of the surgery is mostly left to the discretion of the surgeons based on their experience, expertise, type of haemorrhoids, and risk of relapse. That said, excisional surgery is more painful than other procedures.

Utility of botulinum toxin injection for post-operative pain management after conventional hemorrhoidectomy: a systematic review and meta-analysis of clinical trials

BACKGROUND

Botulinum Toxin (BTX) has been found to have anti-spasm and analgesic effects. The utility of BTX after conventional hemorrhoidectomy remains unclear. Thus, a systematic review and meta-analysis are required to find out its utility after conventional hemorrhoidectomy.

METHODS

Using specific keywords, we comprehensively go through the potential articles on PubMed, ClinicalTrials.gov, and Europe PMC sources until March 27th, 2022. All published studies on botulinum toxin anal sphincter injection after conventional hemorrhoidectomy were collected. We were using Review Manager 5.4 software to conduct statistical analysis.

RESULTS

Five clinical trial studies with a total of 260 patients undergoing hemorrhoidectomy were included in the analysis Our pooled analysis revealed that BTX injection after hemorrhoidectomy was associated with lower VAS at 24 h post-operative [Mean Difference -1.35 (95% CI -1.90, -0.80), p < 0.00001, I2 = 0%] and shorter time to return work [Mean Difference -8.94 days (95% CI -12.57, -5.30), p < 0.00001, I2 = 0%]. However, BTX injection did not differ significantly from placebo in terms of time to first defecation (p = 0.22), fecal incontinence (p = 0.91) and urinary retention incidence (p = 0.18).

CONCLUSION

BTX sphincter injection may offer some benefit after conventional hemorrhoidectomy in reducing pain from the first day after the procedure and promoting wound healing without complication. Further randomized clinical trials are still needed to confirm the results of our study.

Psychological states could affect postsurgical pain after hemorrhoidectomy: A prospective cohort study

Background

Open hemorrhoidectomy is one of the standard procedures for grade IV hemorrhoids. Postsurgical pain is a common problem for patients. We aim to prospectively evaluate potential factors affecting postoperative pain among hemorrhoidectomy patients.

Methods

An observational study was conducted on 360 patients who had undergone Milligan-Morgan open hemorrhoidectomy. Details of the surgery and baseline information were recorded. Preoperative anxiety and depression were analyzed via the self-rating anxiety scale 20 (SAS-20) and self-rating depression scales 20 (SDS-20), respectively. Postoperative pain score was performed daily after surgery until the patient was discharged. The numerical pain score was evaluated by the visual analogue scale (VAS). The association between preoperative psychological states (anxiety or depression) and postoperative pain was analyzed using a generalized additive mixed model.

Results

A total of 340 patients eventually provided complete data and were included in our study. The average age was 43.3 ± 14.4 years, and 62.1% of patients were women. In total, 14.9% of patients had presurgical anxiety and 47.1% had presurgical depression. Postsurgical pain reached a peak point 1-2 days after surgery and went down to a very low level around 4-5 days after surgery. More excision of hemorrhoids could lead to more pain experience after surgery. Presurgical depression was associated with postsurgical pain. Patients who had presurgical depression had higher pain scores after surgery (2.3 ± 1.9 vs. 3.3 ± 1.9, p = 0.025).

Conclusion

Preoperative depression and the amount of excisional hemorrhoids are positively related to postsurgical pain.

Laser hemorrhoidoplasty for hemorrhoidal disease: a systematic review and meta-analysis

Laser hemorrhoidoplasty (LHP) is known as a new minimally invasive and painless procedure for symptomatic hemorrhoids. However, Milligan-Morgan (MM) may offer the best result of long-term cure rates. In this study, we aim to compare the efficacy between LHP and MM for hemorrhoidal disease treatment. Using specific keywords, we comprehensively go through the potential articles on PubMed, Europe PMC, and Google Scholar sources until April 19, 2022. All published studies on LHP and MM hemorrhoidectomy were collected. Statistical analysis was done by using Review Manager 5.4 software. Twelve studies with a total of 1756 patients with hemorrhoid grades II-IV were included for the analysis. Our pooled analysis revealed that LHP was associated with shorter operative time (p < 0.00001), shorter length of hospital stay (p = 0.0005), lower risk of urinary retention (p = 0.005) and anal stenosis (p = 0.0004), and lower VAS 24-h post-operative (p < 0.00001) when compared with MM. However, LHP and MM did not differ in terms of recurrence rate (p = 0.70). LHP was superior to MM procedure in terms of shortening the recovery time and minimizing post-operative complications for patients with hemorrhoidal disease.
