Randomized, prospective trial of direct current versus bipolar electrocoagulation for bleeding internal hemorrhoids

Interventional treatments for prolapsing haemorrhoids: network meta-analysis

BACKGROUND

Multiple treatments for early-moderate grade symptomatic haemorrhoids currently exist, each associated with their respective efficacy, complications, and risks. The aim of this study was to compare the relative clinical outcomes and effectiveness of interventional treatments for grade II-III haemorrhoids.

METHODS

A systematic review was conducted according to PRISMA criteria for all the RCTs published between 1980 and 2020; manuscripts were identified using the MEDLINE, Embase, and CENTRAL databases. Inclusion criteria were RCTs comparing procedural interventions for grade II-III haemorrhoids. Primary outcomes of interest were: symptom recurrence at a minimum follow-up of 6 weeks, postprocedural pain measured on a visual analogue scale (VAS) on day 1, and postprocedural complications (bleeding, urinary retention, and bowel incontinence). After bias assessment and heterogeneity analysis, a Bayesian network meta-analysis was performed.

RESULTS

Seventy-nine RCTs were identified, including 9232 patients. Fourteen different treatments were analysed in the network meta-analysis. Overall, there were 59 RCTs (73 per cent) judged as being at high risk of bias, and the greatest risk was in the domain measurement of outcome. Variable amounts of heterogeneity were detected in direct treatment comparisons, in particular for symptom recurrence and postprocedural pain. Recurrence of haemorrhoidal symptoms was reported by 54 studies, involving 7026 patients and 14 treatments. Closed haemorrhoidectomy had the lowest recurrence risk, followed by open haemorrhoidectomy, suture ligation with mucopexy, stapled haemorrhoidopexy, and Doppler-guided haemorrhoid artery ligation (DG-HAL) with mucopexy. Pain was reported in 34 studies involving 3812 patients and 11 treatments. Direct current electrotherapy, DG-HAL with mucopexy, and infrared coagulation yielded the lowest pain scores. Postprocedural bleeding was recorded in 46 studies involving 5696 patients and 14 treatments. Open haemorrhoidectomy had the greatest risk of postprocedural bleeding, followed by stapled haemorrhoidopexy and closed haemorrhoidectomy. Urinary retention was reported in 30 studies comparing 10 treatments involving 3116 participants. Open haemorrhoidectomy and stapled haemorrhoidopexy had significantly higher odds of urinary retention than rubber band ligation and DG-HAL with mucopexy. Nine studies reported bowel incontinence comparing five treatments involving 1269 participants. Open haemorrhoidectomy and stapled haemorrhoidopexy had the highest probability of bowel incontinence.

CONCLUSION

Open and closed haemorrhoidectomy, and stapled haemorrhoidopexy were associated with worse pain, and more postprocedural bleeding, urinary retention, and bowel incontinence, but had the lowest rates of symptom recurrence. The risks and benefits of each treatment should be discussed with patients before a decision is made.

[Nonsurgical therapy of hemorrhoids]

Hemorrhoids are a clinical and anatomical subject that has not been completely investigated. A link between the anatomy and the symptoms has still not been established. For this reason, it is difficult to class the different treatments. Non-surgical treatment is intended not to remove but to reposition and hold the hemorrhoids in an anatomically correct position and the reduce the vascularity. Different techniques have been studies but not all of them have been approved. For the moment, the recognised techniques include: infrared therapy, sclerotherapy, rubber band ligation. Cryotherapy has not been studied in controlled studies. One hopes that new techniques such as Doppler-guided artery ligation will soon be tested and validated.

Comparison of electrotherapy of hemorrhoids and Ferguson hemorrhoidectomy in a randomized prospective study

BACKGROUND

Ferguson hemorrhoidectomy has been shown to be associated with significant amount of post-operative (post op) pain and complications. However, electrotherapy in which hemorrhoidal tissue is not excised might not be associated with severe complications.

OBJECTIVE

Our aim was to compare the results of Ferguson hemorrhoidectomy with electrotherapy methods using 16 and 30 mA (milliampers) direct current (DC).

METHODS

Four hundred and eight patients with symptomatic hemorrhoids, grades 1, 2 and 3, were randomly assigned into 3 groups. Group A (136 patients) underwent Ferguson hemorrhoidectomy, group B1 (136 patients) and group B2 (136 patients) were subjected to electrotherapy using 16 and 30 mA, respectively. The groups were compared in terms of duration of procedures, duration of hospital stay, post op pain severity and post op complications including recurrence, infection and non-healing ulcers.

RESULTS

All patients in group A had severe pain for 7-14 days of post op. However, in group B1, 88(65%) patients had mild pain during the treatment and 1st post op day; 28(21%) of them could not tolerate the operation; 20(15%) of them had mild pain and 10(7.5%) of them had moderate pain up to day 7. In group B2, 47(35%) of patients had sever pain for 6 h and 20(15%) of them experienced mild pain for 2-7 days post op. The one day hospital stay in group A and group B2 were 82 and 97%, respectively, while patients in group B1 were treated as out patients. Mean procedure time for one hemorrhoidectomy in group A was 23 min, in electrotherapy using 16 and 30 mA was 9.7 and 6.1 min, respectively. The overall success rate with the first application in group B1 was 57% and in group B2 was 93%.

CONCLUSION

Electrotherapy method using 30 mA DC could significantly decrease post op pain, operation time and hospital stay. This method had good success rate and very low post op complications compared to Ferguson hemorrhoidectomy and using 16 mA method. Therefore, due to its effectiveness, less pain, rapidity and safeness, we recommend it.

Prospective randomized comparative study of bipolar electrocoagulation versus heater probe for treatment of chronically bleeding internal hemorrhoids

BACKGROUND

Our purpose was to compare the efficacy, complications, failure rates, and crossovers of heater and bipolar probe treatments of chronically bleeding internal hemorrhoids.

METHODS

Eighty-one patients (31 female, 50 male) with mean age of 53 years had large (grade 2 to 3) internal hemorrhoids with bleeding for a mean of 12 years, had failed medical management, and were randomized in a prospective study of anoscopic treatments to heater versus bipolar probes. Failure was defined as a major complication or failure to reduce the size of all internal hemorrhoids with three or more treatments.

RESULTS

With similar background variables and no difference in treatment times, rectal bleeding and other symptoms were controlled in a shorter time with the heater probe than with the bipolar probe (77 versus 121 days). Five complications (fissures, bleeding, or rectal spasm) occurred with the bipolar probe, and two occurred with the heater probe. The heater probe caused more pain during treatments but had significantly fewer failures and crossovers.

CONCLUSIONS

For patients who had failed medical management of chronically bleeding internal hemorrhoids, the techniques and complications of heater and bipolar probes were similar, but pain was more common, failures and crossovers were less frequent, and the time to symptom relief was shorter with the heater probe than with the bipolar probe.
