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.

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.

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.

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.

Hemorrhoidal disease (HD) is a frequent health problem with considerable repercussions on patients' quality of life. However, much of the clinical practice related to HD is based on knowledge without scientific evidence and supported largely by empirical experience of the physician who deals with this pathology. As in other countries, the goal of this consensus is to establish statements supported by solid scientific evidence and whose purpose will be to standardize and guide the diagnosis and management of HD both in the general population and in some particular groups of patients.

Our purpose was to compare the efficacy, complications, success rate, recurrence rate at 1 year, and crossovers of rubber band ligation (RBL) with those of bipolar electrocoagulation (BPEC) treatment for chronically bleeding internal hemorrhoids.

A total of 45 patients of mean age 51.5 years, who had rectal bleeding from grade II or III hemorrhoids and in whom intensive medical therapy failed, were randomized in a prospective study comparing RBL with BPEC. Treatment failure was predefined as continued bleeding, occurrence of a major complication, or failure to reduce the size of all internal hemorrhoidal segments to grade I in < or =3 treatments. Patients were followed up for 1 year.

With similar patients, rectal bleeding and other symptoms were controlled with significantly fewer treatments of RBL than of BPEC (2.3+/-0.2 vs. 3.8+/-0.4, P<0.05), and RBL had a significantly higher success rate (92% vs. 62%, P<0.05). RBL had more cases of severe pain during treatment (8% vs. 0%, P<0.05), but significantly fewer failures and crossovers (8% vs. 38%). Symptomatic recurrence at 1 year was 10% RBL and 15% BPEC.

For patients with chronically bleeding grade II or III internal hemorrhoids that are unresponsive to medical therapy, safety and complication rates of banding and BPEC were similar. The success rate was significantly higher with RBL than with BPEC. Symptom recurrence rates at 1 year were similar.

Infrared photocoagulation (IRP) is commonly used in the treatment of hemorrhoids, but rectal bleeding can persist after this procedure. Adjuvant therapy may thus be considered for more definitive control of symptoms, particularly bleeding.

The goal of this study was to compare the efficacy of a treatment combining IRP and oral micronized purified flavonoid fraction (MPFF) versus each treatment used alone on bleeding cessation in patients with grades I, II, and III acute internal hemorrhoids.

This was a prospective, randomized, controlled, single-blind study. Consecutive outpatients were randomly assigned to a treatment combining MPFF and IRP or to each treatment separately. For each patient, bleeding status was reported at day 0 (day of inclusion) and compared with that at day 5 after treatment by observers blinded to treatment assignment. Follow-up visits were planned at days 7, 30, 60, and 90 of therapy, including monitoring of treatment-related side effects and self-reporting by patients of any problem related to hemorrhoidal disease.

A total of 351 patients (180 women, 171 men) were enrolled in the study. Their mean age was 49.2 years (range, 29-71 years). Hemorrhoids were grade I in 33.6% (118 patients), grade II in 48.7% (171 patients), and grade III in 17.7% (62 patients) of the study population. Patients were randomly assigned to each of the 3 treatment groups (117 patients in each), with no significant difference between groups in the age, sex, or distribution of grade of hemorrhoids. The percentage of patients with no bleeding after 5 days of treatment was higher in the combined treatment group (74.8%) compared with MPFF alone (59.6%; P = 0.023) or with IRP alone (55.6%; P = 0.004). MPFF alone was as effective as IRP alone at stopping bleeding. Patients with grades I and II hemorrhoids responded significantly better (82.5% and 61.7%, respectively) to either treatment than those with grade III hemorrhoids (22.9%; P < 0.001). Of the 216 patients who were followed up for 90 days, 3 had a gastrointestinal adverse event, and 19 had a relapse of bleeding.

Five days of treatment combining MPFF with IRP significantly reduced bleeding status in these study patients with grades I and II acute internal hemorrhoids compared with each treatment used alone.

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

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.

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.

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.

The purpose of this study was to assess whether any method of hemorrhoid therapy has been shown to be superior in randomized, controlled trials.

A meta-analysis was performed of all randomized, controlled trials assessing two or more treatment modalities for symptomatic hemorrhoids. Outcome variables included response to therapy, need for further therapy, complications, and pain.

A total of 18 trials were available for analysis. Hemorrhoidectomy was found to be significantly more effective than manual dilation of the anus (P = 0.0017), with less need for further therapy (P = 0.034), no significant difference in complications (P = 0.60), but significantly more pain (P < 0.0001). Patients undergoing hemorrhoidectomy had a better response to treatment than did patients treated with rubber band ligation (P = 0.001), although complications were greater (P = 0.02) as was pain (P < 0.0001). Rubber band ligation was better than sclerotherapy in response to treatment for all hemorrhoids (P = 0.005) as well as for hemorrhoids stratified by grade (Grades 1 to 2; P = 0.007; Grade 3 hemorrhoids, P = 0.042), with no difference in the complication rate (P = 0.35). Patients treated with sclerotherapy (P = 0.031) or infrared coagulation (P = 0.0014) were more likely to require further therapy than those treated with rubber band ligation, although pain was greater after rubber band ligation (P = 0.03 for sclerotherapy; P < 0.0001 for infrared coagulation).

Rubber band ligation is recommended as the initial mode of therapy for Grades 1 to 3 hemorrhoids. Although hemorrhoidectomy showed better response rates, it is associated with more complications and pain than rubber band ligation, thus should be reserved for patients who fail to respond to rubber band ligation.

Internal hemorrhoids are the most common cause of lower gastrointestinal bleeding. Although new anoscopic therapies are available, few comparative randomized studies have evaluated them in regard to long-term efficacy, recurrence rates, and safety. Our purpose was to compare the treatment of internal hemorrhoids with direct current (Ultroid, Cabot Medical, Langhorn, Pa.) and bipolar (BICAP, Circon ACMI, Stamford, Conn.) hemorrhoid probes. One hundred patients with symptomatic internal hemorrhoids were randomized: 50 to direct current electrocoagulation and 50 to bipolar electrocoagulation. Follow-up and treatment were at 3- to 4-weekly intervals; two to three hemorrhoid segments were treated at each session until relief of symptoms (bleeding, prolapse, and discharge) and a reduction in hemorrhoid size to grade 1 or 0 were noted. The hemorrhoids of 98% of all patients studied were grade 2 or 3; 2% of patients had grade 1 hemorrhoids and none had grade 4 hemorrhoids. At 1 year after treatment, most patients had no (69%) or only mild (23%) recurrence, and a few had severe, symptomatic (8%) hemorrhoid recurrence. A greater recurrence rate was noted after direct current treatment (34%) than bipolar treatment (29%). In contrast, rebleeding at 1 year occurred less frequently after direct current treatment (5%) than after bipolar treatment (20%). Our conclusions were as follows: (1) Both direct current and bipolar probes were effective for control of chronic bleeding from grade 1 to 3 internal hemorrhoids. (2) Bipolar probe was significantly faster than direct current probe. (3) Direct current treatment produced fewer complications than bipolar treatment (12% versus 14%). (4) Recurrence rates were low after 1 year with either device (8%).(ABSTRACT TRUNCATED AT 250 WORDS)

Fifty patients with bleeding internal hemorrhoids unresponsive to 6 weeks of standard medical therapy were randomly assigned to receive treatment with direct current or bipolar electrocoagulation. Treatment groups were similar in bleeding severity and internal hemorrhoid grade. Treatment sessions were significantly longer for direct current electrocoagulation (8.8 +/- 0.2 minutes) than for bipolar electrocoagulation (0.1 +/- 0.03 minutes) (p < 0.001). When compared to the bipolar electrocoagulation group, direct current electrocoagulation patients had more procedural pain that terminated therapy (5 of 25 patients [20%] versus 0 of 25 [0%], for a difference of 20% [95% confidence interval, 4% to 36%]; p = 0.05) and prolonged pain after the procedure (4 of 25 patients [16%] versus 1 of 25 [4%], for a difference of 12% [95% confidence interval, -4% to 28%]; p = 0.35). However, more post-treatment rectal ulcerations were seen in the bipolar electrocoagulation-treated group (6 of 25 patients [24%] versus 1 of 25 [4%], for a difference of 20% [95% confidence interval, 2% to 38%]; p = 0.10). Treatment groups did not differ in number of treatment sessions or months of follow-up. The rates of success, defined as obliteration of the hemorrhoids or cessation of bleeding with reduction of the hemorrhoids to grade 1 or less, for the direct current electrocoagulation and the bipolar electrocoagulation groups were 88% and 92%, respectively. Failures in the direct current electrocoagulation group were uncontrollable bleeding (n = 1) and refusal to continue therapy because of pain (n = 2).(ABSTRACT TRUNCATED AT 250 WORDS)

Recently, laser technology has been advocated for the treatment of hemorrhoids. However, there has been little scientific evaluation of the use of the Nd:YAG laser for excisional treatment of hemorrhoidal disease. The purpose of this study was to perform a prospective randomized study of the Nd:YAG laser vs. scalpel excision, when performing a standard Ferguson-closed hemorrhoidectomy.

Patients presenting for internal-external hemorrhoidectomy were eligible for study. Hemorrhoidectomies were performed under epidural or caudal blocks. The standard Ferguson closed hemorrhoidectomy technique was used. Data evaluated included: age, sex, estimated blood loss, operative time, postoperative pain scores, postoperative analgesic use, wound healing, and time for return to work. Eighty-six patients were eligible for study (laser, N = 51; scalpel, N = 35).

There were no significant differences between the groups, except for a greater degree of wound inflammation and dehiscence at the 10 day postoperative visit for the laser group (laser, 1.7 +/- .2; scalpel, 0.8 +/- .2; P < 0.05, t-test). The use of the Nd:YAG laser added $480 per case; as a result, the treatment cost for the laser group was $15,360 higher than that of the conventional group.

The results indicate that there are no patient care advantages associated with the use of the Nd:YAG laser for excisional hemorrhoidectomy compared with scalpel excision. As new technology becomes available, surgeons must rigorously assess therapeutic efficacy and cost-benefit ratio before deciding to employ this technology for patient care.

Hemorrhoids should be classified so that the treatment can be individualized. Minor or asymptomatic hemorrhoids usually do not require any treatment. Diet modification is a useful adjunct in all degrees of hemorrhoids. Fixation procedures may be employed in the office for first-, second-, and minor third-degree hemorrhoids. These techniques are valuable in elderly and poor-risk patients. Excisions may be performed by standard instruments or lasers with good results. These techniques may be employed with local anesthesia and in an outpatient setting. Lasers may be effective as either a fixation device or an excisional tool. The problem is cost and maintenance of the equipment and the cost of the disposable apparatus. If the equipment is already available or can be shared for multidisciplinary use, hemorrhoidectomy can be accomplished in a cost-effective manner with excellent results.

Many new modalities have been developed to treat symptomatic hemorrhoidal disease. In order to determine whether direct current electrotherapy therapy is effective, a prospective, crossover study was done. Sixteen patients referred for treatment of symptomatic hemorrhoids underwent a 16-week treatment protocol. Patients were randomized to receive either medical therapy with a sham therapy, or medical therapy with active direct current electrotherapy at 4-week intervals. All patients were instructed in medical therapy including sitz baths, hydrocortisone suppositories, topical preparations, and a high fiber diet with an educational booklet. Patients who did not respond to initial therapy were crossed over at 8 weeks, receiving alternate therapy twice. Improvement in symptoms, or lack thereof, was not statistically different between the two treatment groups. Comparisons of the internal sphincter pressure, external sphincter pressure, maximum squeeze pressure, and rectal sensitivity to balloon insufflation (volume) were not statistically different before, during, or after any treatment modality (p = 0.46, 0.60, 0.33). The size and grade of hemorrhoids on entry into the study had no bearing on the outcome. In a prospective crossover trial, no difference could be found between standard medical therapy and direct current electrotherapy in the treatment of symptomatic-hemorrhoidal disease.
