Topical diltiazem for pain after closed hemorrhoidectomy

Comparison of ointment-based agents after excisional procedures for hemorrhoidal disease: a network meta-analysis of randomized controlled trials

INTRODUCTION

Efficient postoperative pain control is important after hemorrhoidal surgery. Although several locally applied medications have been used, current evidence regarding the optimal strategy is still conflicting. This network meta-analysis assessed analgesic efficacy and safety of the various topical medications in patients submitted to excisional procedures for hemorrhoids.

METHODS

The present study followed the Cochrane Handbook for Systematic Reviews of Interventions and the PRISMA guidelines. The last systematic literature screening was performed at 15 June 2023. Comparisons were based on a random effects multivariate network meta-analysis under a Bayesian framework.

RESULTS

Overall, 26 RCTs and 2132 patients were included. Regarding postoperative pain, EMLA cream (surface under the cumulative ranking curve (SUCRA) 80.3%) had the highest ranking at 12-h endpoint, while aloe vera cream (SUCRA 82.36%) scored first at 24 h. Metronidazole ointments had the highest scores at 7 and 14 days postoperatively. Aloe vera had the best analgesic profile (24-h SUCRA 84.8% and 48-h SUCRA 80.6%) during defecation. Lidocaine (SUCRA 87.9%) displayed the best performance regarding overall morbidity rates.

CONCLUSIONS

Due to the inconclusive results and several study limitations, further RCTs are required.

Still a Case of "No Pain, No Gain"? An Updated and Critical Review of the Pathogenesis, Diagnosis, and Management Options for Hemorrhoids in 2020

The treatment of haemorrhoids remains challenging: multiple treatment options supported by heterogeneous evidence are available, but patients rightly demand a tailored approach. Evidence for newer surgical techniques that promise to be less painful has been conflicting. We review the current evidence for management options in patients who present with varying haemorrhoidal grades. A review of the English literature was performed utilizing MEDLINE/PubMed, Embase, and Cochrane databases (31 May 2019). The search terms (haemorrhoid OR haemorrhoid OR haemorrhoids OR haemorrhoids OR “Hemorrhoid”[Mesh]) were used. First- and second-degree haemorrhoids continue to be managed conservatively. The easily repeatable and cost-efficient rubber band ligation is the preferred method to address minor haemorrhoids; long-term outcomes following injection sclerotherapy remain poor. Conventional haemorrhoidectomies (Ferguson/Milligan-Morgan/Ligasure haemorrhoidectomy) still have their role in third- and fourth-degree haemorrhoids, being associated with lowest recurrence; nevertheless, posthaemorrhoidectomy pain is problematic. Stapled haemorrhoidopexy allows quicker recovery, albeit at the costs of higher recurrence rates and potentially serious complications. Transanal Haemorrhoidal Dearterialization has been promoted as nonexcisional and less invasive, but the recent HubBLe trial has questioned its overall place in haemorrhoid management. Novel “walk-in-walk-out” techniques such as radiofrequency ablations or laser treatments will need further evaluation to define their role in modern-day haemorrhoid management. There are numerous treatment options for haemorrhoids, each with their own evidence-base. Newer techniques promise to be less painful, but recurrence rates remain an issue. The balance continues to be sought between long-term efficacy, minimisation of postoperative pain, and preservation of anorectal function.

Topical analgesia following excisional haemorrhoidectomy: a systematic review and meta-analysis of randomised controlled trials

PURPOSE

Post-operative pain following excisional haemorrhoidectomy poses a particular challenge for patient recovery, as well as a burden on hospital resources. There appears to be an increasing role for topical agents to improve this pain, but their efficacy and safety have not been fully assessed. This systematic review aims to assess all topical agents used for pain following excisional haemorrhoidectomy.

METHODS

The study was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Two authors independently assessed MEDLINE, EMBASE, and CENTRAL databases to 27 June 2019. All randomised controlled trials (RCTs) in English that investigated topical agents following excisional haemorrhoidectomy were included. Meta-analysis was performed using Review Manager, version 5.3.

RESULTS

A total of 3639 records were identified. A final 32 RCTs were included in the qualitative analysis. Meta-analysis was performed on 9 RCTs that investigated glyceryl trinitrate (GTN) (5 for diltiazem, 2 for metronidazole and 2 for sucralfate). There were mixed significant changes in pain for GTN compared with placebo. Diltiazem resulted in significant reduction of pain on post-operative days 1, 2, 3 and 7 (p < 0.00001). Metronidazole resulted in significant reduction of pain on days 1 (p = 0.009), 7 (p = 0.002) and 14 (p < 0.00001). Sucralfate resulted in signification reduction of pain on days 7 and 14 (both p < 0.00001).

CONCLUSION

Topical diltiazem, metronidazole and sucralfate appear to significantly reduce pain at various timepoints following excisional haemorrhoidectomy. GTN had mixed evidence. Several single trials identified other promising topical analgesics.

A prospective randomized double-blind study of pain control by topical calcium channel blockers versus placebo after Milligan-Morgan hemorrhoidectomy

INTRODUCTION

Post-hemorrhoidectomy pain is significantly associated with a hypertonicity of the internal anal sphincter. We evaluated the effects of topical diltiazem, a calcium channel blocker, in reducing pain after hemorrhoidectomy. Purpose of our study was to determine difference in extent of pain control by application of topical calcium channel blocker (diltiazem 2%) versus placebo ointment.

METHODS

This was a prospective randomized double-blind clinical study conducted at Sawai Man Singh Hospital, Jaipur, from May 2016 to May 2017. Sixty patients, who had undergone hemorrhoid, were randomly assigned to receive 2% diltiazem ointment (n = 30) or a placebo ointment (n = 30) postoperatively. Ointments were applied to the perianal region three times daily for 7 days. Pain scores were recorded using visual analog scale at 6, 24, and 48 h and seventh day postoperatively and number of analgesic doses consumed by patients in the first 3 days.

RESULTS

Patients using the diltiazem ointment had significantly less pain and greater benefit than those in the placebo group throughout the first postoperative week (p < 0.001) except for reading at 6 h. Also, there was significantly less number of analgesic doses consumed in the diltiazem group compared to the placebo group.

CONCLUSION

Perianal application of 2% diltiazem ointment after hemorrhoidectomy significantly reduces postoperative pain and is perceived as beneficial.
