Hemorrhoid banding using videoendoscopic anoscopy and a single-handed ligator: an effective, inexpensive alternative to endoscopic band ligation

Long-term outcome and efficacy of endoscopic hemorrhoid ligation for symptomatic internal hemorrhoids

AIM: To assess the long-term outcome of endoscopic hemorrhoid ligation (EHL) for the treatment of symptomatic internal hemorrhoids.

METHODS: A total of 759 consecutive patients (415 males and 344 females) were enrolled. Clinical presentations were rectal bleeding (593 patients) and mucosal prolapse (166 patients). All patients received EHL at outpatient clinics. Hemorrhoid severity was classified by Goligher’s grading. The mean follow-up period was 55.4 mo (range, 45-92 mo).

RESULTS: The number of band ligations averaged 2.35 in the first session for bleeding and 2.69 for prolapsed patients. Bleeding was controlled in 587 (98.0%) patients, while prolapse was reduced in 137 (82.5%) patients. After treatment, 93 patients experienced anal pain and 48 patients had mild bleeding. Patient subjective satisfaction was 93.6%. Repeat treatment or surgery was performed if symptoms were not relieved in the first session. In the bleeding group, the recurrence rate was 3.7% (22 patients) at 1 year, and 6.6% and 13.0% at 2 and 5 years. In the prolapsed group, the recurrence rate was 3.0%, 9.6% and 16.9% at 1, 2 and 5 years, respectively.

CONCLUSION: EHL is an easy and well-tolerated procedure for the treatment of symptomatic internal hemorrhoids, with good long-term results.

Elastic band ligation of hemorrhoids: Flexible gastroscope or rigid proctoscope?

AIM: To compare rigid proctoscope and flexible endoscope for elastic band ligation of internal hemorrhoids.

METHODS: Patients between 18 and 80 years old, with chronic complaints (blood loss, pain, itching or prolapse) of internal hemorrhoids of grade I-III, were randomized to elastic band ligation by rigid proctoscope or flexible endoscope (preloaded with 7 bands). Patients were re-treated every 6 wk until the cessation of complaints. Evaluation by three-dimensional anal endosonography was performed.

RESULTS: Forty-one patients were included (median age 52.0, range 27-79 years, 20 men). Nineteen patients were treated with a rigid proctoscope and twenty two with a flexible endoscope. Twenty-nine patients had grade I hemorrhoids, 9 patients had grade II hemorrhoids and 3 patients had grade III hemorrhoids. All patients needed a minimum of 1 treatment and a maximum of 3 treatments. A median of 4.0 bands was used in the rigid proctoscope group and a median of 6.0 bands was used in the flexible endoscope group (P < 0.05). Pain after ligation tended to be more frequent in patients treated with the flexible endoscope (first treatment: 3 vs 10 patients, P < 0.05). Three-dimensional endosonography showed no sphincter defects or alterations in submucosal thickness.

CONCLUSION: Both techniques are easy to perform, well tolerated and have a good and fast effect. It is easier to perform more ligations with the flexible endoscope. Additional advantages of the flexible scope are the maneuverability and photographic documentation. However, treatment with the flexible endoscope might be more painful and is more expensive.

Prospective randomized clinical trial on suction elastic band ligator versus forceps ligator in the treatment of haemorrhoids

OBJECTIVE

This prospective randomized clinical trial was undertaken to compare the use of a single-operator vacuum suction ligator and the traditional forceps ligator in terms of pain perception following the procedure, intra-procedure bleeding and other complications.

METHODS

One hundred consecutive patients with second- and third-degree haemorrhoids presenting between July 2002 and September 2003 were randomized into suction and forceps groups for rubber band ligations. They were equally distributed in both groups, with a mean age of 48.7 years (range, 15-83 years). The immediate, 24-hour, 7-day and 14-day pain scores after the procedure were evaluated using a visual analogue scale. Intra-procedure bleeding and other complications at follow-up were evaluated.

RESULTS

Pain perception was worse in the forceps group immediately after ligation, with a mean score of 6.08 compared with 3.08 in the suction group (p < 0.001). Pain score remained high among the forceps patients at 24 hours post-banding, with a mean score of 4.00 compared with 1.92 in the suction group (p < 0.001). There was no significant difference in terms of immediate and 24-hour pain perceptions whether two or three haemorrhoids were banded per session (p = 0.904 and p = 0.058). The amount of analgesia consumed after banding correlated well with the severity of pain reported, being higher among the forceps group with a mean of 4.48 tablets (p = 0.003). Intra-procedure bleeding occurred in 25 patients in the forceps group compared with five in the suction group (p < 0.001). There were no severe complications such as perianal sepsis, urinary retention, sphincter dysfunction or bleeding during the trial.

CONCLUSION

Suction band ligation is superior to forceps ligation for the treatment of second- and third-degree haemorrhoids in terms of pain tolerance, amount of analgesia consumed and intra-procedure bleeding.

Hemorrhoidal elastic band ligation with flexible videoendoscopes: a prospective, randomized comparison with the conventional technique that uses rigid proctoscopes

BACKGROUND

Elastic band ligation by means of a rigid proctoscope is the treatment of choice for patients with symptoms caused by internal hemorrhoids of grade 2 to 3. In contrast to the flexible videoendoscope, the rigid proctoscope has limited maneuverability, has a narrower field of view, and does not allow adequate documentation. Therefore, a randomized trial was conducted to compare the safety and the efficacy of conventional elastic band ligation with videoendoscopic elastic band ligation.

METHODS

A total of 100 consecutive patients (mean age 47 [12] years) with chronically bleeding grade 2 or 3 internal hemorrhoids were randomized to elastic band ligation or videoendoscopic elastic band ligation. For videoendoscopic elastic band ligation, a reusable multiband ligator was attached to the end of a therapeutic upper videoendoscope. From one to 3 bands were placed per session in both groups. Re-treatment was performed every 2 to 3 weeks in both groups until cessation of bleeding and eradication of the hemorrhoids (at least grade 2) were achieved. Thereafter, the patients were followed to assess complications and efficacy. Recurrent bleeding was considered a treatment failure.

RESULTS

To achieve the desired therapeutic aims, a significantly lower number of treatment sessions was required in the videoendoscopic elastic band ligation group (1.8 [0.8] vs. 2.4 [0.9]; p < 0.01) and the total number of bands applied was significantly less (2.8 [1.1] vs. 3.7 [1.4]; p < 0.01). Pain was noted after ligation by 25% of patients in the elastic band ligation group compared with 27% of those who had videoendoscopic elastic band ligation. However, analgesic medications were required in only 7% after elastic band ligation and 9% after videoendoscopic elastic band ligation (NS). Post-ligation bleeding that had to be treated endoscopically occurred in 3.5% of the patients of the elastic band ligation group and 3.2% of those in the videoendoscopic elastic band ligation group (NS). Blood transfusion was not required. At a median follow-up of 12 months, there was no recurrence of bleeding in 40 patients (80%) in the conventional elastic band ligation group vs. 43 (86%) in the videoendoscopic elastic band ligation (NS).

CONCLUSIONS

The long-term efficacy and safety of conventional elastic band ligation and videoendoscopic elastic band ligation are highly comparable. However, when videoendoscopic elastic band ligation is performed, significantly fewer treatment sessions are required.

Medical management of fecal incontinence

Diarrhea and constipation are known risk factors for fecal incontinence. This report reviews how to diagnose and medically treat patients with chronic diarrhea, chronic constipation with overflow incontinence, and incontinence resulting from rectal mucosal prolapse secondary to hemorrhoids. Antidiarrheal agents (including loperamide, diphenoxylate, and difenoxin) and the tricyclic antidepressant amitriptyline improve continence in patients with diarrhea-associated incontinence. Other antidiarrheal agents are under investigation. The mechanism is believed to be decreased intestinal motility and stool frequency resulting in more formed stools. Increases in anal canal resting pressure may also contribute to improvement in continence. Adverse effects are constipation from excessive use. In addition to antidiarrheal drugs, fiber supplements may improve incontinence associated with diarrhea. Transient, benign cases of constipation usually respond to increasing fluid intake and dietary fiber, improving mobility, or eliminating the concurrent use of constipating drugs. For mild to moderate constipation, bulking agents, laxatives, and stool softeners are used cautiously so as not to excessively loosen stools and exacerbate anal incontinence. Laxatives have been shown to improve continence, possibly through the mechanism of eliminating fecal impaction. Prolapsing hemorrhoids may partially obstruct defecation and cause soilage from the passage of fecal material, mucus, or blood. With endoscopic banding, a ligator is attached to an endoscope and a tight band is placed around the enlarged vein, causing the hemorrhoid to thrombose.

Endoscopic hemorrhoidal ligation of symptomatic internal hemorrhoids

BACKGROUND

This study assessed the efficacy of endoscopic hemorrhoidal ligation for treatment of patients with symptoms caused by internal hemorrhoids.

METHODS

A total of 576 consecutive patients with symptoms caused by internal hemorrhoids were enrolled in the study. Symptoms were rectal bleeding (239 patients) and prolapse (337 patients). The severity of the hemorrhoids was classified by using the grading system of Goligher.

RESULTS

All patients were treated by the same operator. Mean follow-up was 17.5 months (range 8 to 24 months). The mean number of band ligations per session was 2.86. The mean number of treatment sessions was 1.24. At least one grade reduction in the severity of the hemorrhoids was achieved in most patients (93.58%). Moreover, rectal bleeding was controlled in 228 patients (95.4%), and rectal prolapse was reduced in 310 patients (91.99%). After treatment, 85 patients experienced anal pain, 37 had mild bleeding, 4 developed external hemorrhoidal thrombosis, and one had a peri-anal abscess. The latter 5 patients were treated surgically and recovered uneventfully.

CONCLUSIONS

Endoscopic hemorrhoidal ligation is a simple, safe, and effective treatment for patients with symptoms caused by internal hemorrhoids.

Infrared coagulation versus rubber band ligation in early stage hemorrhoids

The ideal therapy for early stages of hemorrhoids is always debated. Some are more effective but are more painful, others are less painful but their efficacy is also lower. Thus, comfort or efficacy is a major concern. In the present randomized study, a comparison is made between infrared coagulation and rubber band ligation in terms of effectiveness and discomfort. One hundred patients with second degree bleeding piles were randomized prospectively to either rubber band ligation (N = 54) or infrared coagulation (N = 46). Parameters measured included postoperative discomfort and pain, time to return to work, relief in incidence of bleeding, and recurrence rate. The mean age was 38 years (range 19-68 years). The mean duration of disease was 17.5 months (range 12 to 34 months). The number of male patients was double that of females. Postoperative pain during the first week was more intense in the band ligation group (2-5 vs 0-3 on a visual analogue scale). Post-defecation pain was more intense with band ligation and so was rectal tenesmus (P = 0.0059). The patients in the infrared coagulation group resumed their duties earlier (2 vs 4 days, P = 0.03), but also had a higher recurrence or failure rate (P = 0.03). Thus, we conclude that band ligation, although more effective in controlling symptoms and obliterating hemorrhoids, is associated with more pain and discomfort to the patient. As infrared coagulation can be conveniently repeated in case of recurrence, it could be considered to be a suitable alternative office procedure for the treatment of early stage hemorrhoids.

Retroflexed endoscopic band ligation of bleeding internal hemorrhoids

BACKGROUND

Elastic band ligation is a well-established nonoperative method for treatment of bleeding internal hemorrhoids, stages II-III. Usually, one or two bands are placed at a single session by using rigid instruments. The aim of this study was to assess the feasibility, tolerability, safety, and efficacy of multiple band ligation of internal hemorrhoids performed in one session by using a flexible endoscope with an attached band ligation device in the retroflexed position.

METHODS

Eighty-three patients with chronically bleeding and/or prolapsing internal hemorrhoids were treated by retroflexed endoscopic band ligation. From 1 to 6 bands were placed in a single session. Bands were targeted at the apex and proximal body of the internal hemorrhoid so that final band placement was entirely proximal to the dentate line. Malpositioned bands were removed by using a novel method. Patients were followed prospectively to assess tolerance, complications, and efficacy. Retreatment was offered if the desired result was not achieved.

RESULTS

A mean of 3.0 (SD 1.2) bands (range 1-6) were placed in a single session. Five percent of bands were malpositioned and removed. Patients were followed for 26 (17) months (range 1-52 months). An excellent result was achieved in 80% of patients with stage II hemorrhoids. Patients with stage II hemorrhoids were more likely to have an excellent result compared with patients with stage III hemorrhoids (80% vs. 54%, p < 0.01). Retroflexed endoscopic band ligation was well tolerated overall. The rate of major, nonfatal complications was 4%.

CONCLUSIONS

Retroflexed endoscopic band ligation is a feasible, well-tolerated, effective, and safe for treatment of bleeding stage II internal hemorrhoids. A novel method of endoscopic band removal is described.
