Endoscopic hemorrhoid band ligation (HBL) is an important advancement in the treatment of symptomatic internal hemorrhoids. This procedure is simple, safe, and effective. Multiple rubber bands can be applied in one session, and further bands can be applied in subsequent sessions if a single session fails to completely eradicate the internal hemorrhoids. The treatment success rate is high, while the long-term recurrence rate is low.
Symptomatic hemorrhoids in adults is considered one of the most prevalent anorectal disorders. Hemorrhoids of different grades can be found in more than 80-90% of patients undergoing sigmoidoscopy or colonoscopy. [1] Hemorrhoids are either internal or external depending on the localization above or below the dentate line. [2]
Internal hemorrhoids may be classified into four grades on the basis of the Goligher system, as follows [2] :
Grade I, II, and III hemorrhoids are managed nonsurgically, whereas grade IV hemorrhoids require surgical intervention.
Stiegman and Goff were the first to propose the technique of elastic band ligation for the treatment of esophageal and gastric varices using a gastroscope, [3, 4] and that technique was also applied to treat symptomatic internal hemorrhoids. Two devices can be used: a smaller one with a gastroscope and a larger one with a colonoscope.
Patients with symptomatic internal hemorrhoids in whom conservative management has failed or who request a nonsurgical therapeutic modality are candidates for HBL. [5] In addition, patients who cannot tolerate surgery, given the risk of anesthesia, may be advised to undergo banding instead of hemorrhoidal surgery.
HBL also provides an alternative therapeutic modality in patients at higher risk for bleeding (cirrhosis and uremia). A significant advantage of HBL is that it can be performed repeatedly, if needed, with further sessions for patients whose symptoms persist after the first session. [6, 7]
Contraindications for HBL include the following [8] :
HBL is contraindicated in patients who are receiving anticoagulants or who have a bleeding disorder, as well as those with concurrent anorectal sepsis. [9]
Preparation includes conscious or deep sedation. Internal hemorrhoids should be graded to achieve optimal management results.
Patients should be asked about their medications (mainly antithrombotics and antiplatelets) before the procedure so as to minimize the risk of early and late bleeding after band ligation.
Misapplication of the band below the dentate line should be avoided; if it is not, severe anal pain may ensue. In some cases, thrombosis is caused by leftover hemorrhoids distal to the rubber band, and therefore ligation must be applied close to the dentate line. [8] Sepsis and hemorrhage may result from ulceration and sloughing after banding. [10]
The success rate of HBL is in the range of 70-97%. [2] Favorable outcomes depend on the banding technique, the internal hemorrhoid grade, and the timing of the follow-up. [8]
Other endoscopic nonoperative techniques used for the treatment of symptomatic internal hemorrhoids include sclerotherapy, cryotherapy, and infrared coagulation. [11]
HBL using video-endoscopic anoscopy compared favorably with traditional banding via anoscopy. [8, 12] The ability to perform band ligation in the clinic makes this technique a popular treatment option for internal hemorrhoids. [13] In addition, the rubber bands used for this procedure are inexpensive and are easy to deploy.
In a meta-analysis of 18 prospective randomized trials performed by MacRae and McLeod, band ligation was the most effective among office-based procedures, with a lower recurrence rate. [12] Several internal hemorrhoidal treatment modalities were compared, and it was concluded that band ligation was superior to sclerotherapy, which demonstrated good short-term but poor long-term benefits. [12] With cryosurgery, patient satisfaction was less, and local complications were more frequent. A cap-assisted endoscopic sclerotherapy approach has been described, which is reported to be convenient, safe, and effective. [14]
Compared to infrared coagulation, band ligation causes more pain but has a lower recurrence rate. [15, 16] In a study by Gupta et al, 80 patients with grade II bleeding internal hemorrhoids were prospectively randomized to undergo HBL (n=44) or radiofrequency ablation (RFA; n=36). Patients in the RFA group had longer procedure times and higher recurrence rates, but earlier return to work (2 days vs 5 days). Pain and tenesmus were more severe with band ligation.
Stiegman and Goff were the first to propose the technique of elastic band ligation for the treatment of esophageal and gastric varices using a gastroscope, [3, 4] and that technique was also applied to treat symptomatic internal hemorrhoids. Two devices can be used: a smaller one to a gastroscope and a larger one to a colonoscope.
In 1997, following band ligation, 95% of internal hemorrhoids were downgraded by more than one point, as reported by Trowers et al. [17] Afterward, the retroflexion manoeuver was introduced by Berkelhammer and Moosvi, [18] with excellent results noted in more than 80% of cases (the highest success rates were in patients with grade II internal hemorrhoids).
Su et al enrolled a total of 759 consecutive patients (415 males, 344 females) to assess the long-term outcome of endoscopic HBL for the treatment of symptomatic internal hemorrhoids. The clinical presentations were bleeding per rectum (n=593) and mucosal prolapse (n=166). All patients underwent the procedure in outpatient clinics. The mean follow-up period was 55.4 months. The average number of bands used ranged from 2.35 to 2.69. Bleeding was controlled in 98% of patients; 82.5% reported reduction in the prolapse. Anal pain was reported in 93 patients, bleeding in 48. The mean recurrence rate was 3.7% at 1 year, 6.6% at 2 years, and 13% at 5 years; 93.6% of patients were satisfied with the procedure. [2]
Forty-one patients (20 men, 21 women) were enrolled in a study comparing rigid proctoscopy (n=19) with flexible gastroscopy (n=22) by Cazemier et al. [19] The median age was 52 years. Twenty-nine patients had grade I, nine had grade II, and three had grade III internal hemorrhoids. A median of four bands were used with the rigid scope, whereas six were used in the flexible endoscope group. Three versus 10 patients reported postligation pain when a rigid proctoscope was used rather than a flexible gastroscope. No sphincter defects were reported with this technique. [19, 20]
