Endoscopic hemorrhoidal ligation: preliminary clinical experience

Rubber band ligation or shaobei injection for the endoscopic treatment of symptomatic hemorrhoids? A retrospective study

BACKGROUND

It is unknown whether Shaobei injection is superior to band ligation for endoscopic symptomatic hemorrhoid treatment. We compared the clinical efficacy, safety, and health economics of the two techniques.

AIMS

This study aims to compare the efficacy, safety and health economics of endoscopic injection of Shaobei and endoscopic ligation in the treatment of grade I-IV symptomatic hemorrhoids.

METHODS

This retrospective cohort study collected clinical data from 413 patients with grade I-IV symptomatic hemorrhoids treated with endoscopy between January 2019 and March 2023. Recurrence rate, postoperative complications, hospitalization costs, hospitalization time, postoperative quality of life (QoL), and postoperative satisfaction were compared between Shaobei injection (treatment group; n = 79) and band ligation (control group; n = 334) groups within 3 months postoperatively.

RESULTS

Before propensity score matching (PSM), the basic characteristics of patients significantly differed between groups (P < 0.05); no differences existed after PSM (Shaobei injection: n = 53; band ligation: n = 83). Recurrence rates did not differ between groups at 3 months postoperatively (P = 0.439). Postoperative symptom grading did not differ between groups (all P > 0.05) but was improved from baseline (all P < 0.001). However, the injection group experienced significantly less pain than the band ligation group on postoperative days 1 (P < 0.001) and 7 (P = 0.003). Significantly lower incidences were observed in the injection than in the ligation group for postoperative anal distention within 1 day (P < 0.001) and complications within 7 days (P < 0.001). No differences between groups were observed for other variables.

CONCLUSION

Endoscopic Shaobei injection is effective and safe for treating grade I-IV symptomatic hemorrhoids, with less postoperative discomfort and fewer postoperative complications than with band ligation.

Shifting Paradigms in Hemorrhoid Management: The Emergence and Impact of Cap-Assisted Endoscopic Sclerotherapy

Hemorrhoidal disease (HD) is a prevalent proctological condition that has puzzled people since ancient times, and the most common symptom is painless bleeding. Traditional treatments include conservative treatment, nonsurgical office-based treatments, and surgery. Sclerotherapy is one of the oldest forms of nonoperative intervention and is widely used to treat internal hemorrhoids with the development of endoscopy technology. However, sclerotherapy is always accompanied by complications such as bleeding, pain, abscess, etc., when the sclerosant is injected into the wrong site. Cap-assisted endoscopic sclerotherapy (CAES), a new minimally invasive technology, was first time coined in 2015 for the treatment of hemorrhoidal disease. The left-posterior-right-anterior (LPRA) anus positioning method under endoscopy provides reliable methodological support for advancing hemorrhoidal treatment via endoscopy. The current trend is that treatment for HD has shifted from being performed predominantly by the Department of Proctology Surgery to being managed mostly by the Department of Gastroenterology. This review reviewed the shifting paradigms of sclerotherapy for HD and discussed the emerging development of CAES.

Effect of lidocaine on postoperative analgesia of endoscopic rubber band ligation combined with injection sclerotherapy for treatment of internal hemorrhoids: A retrospective study (with video)

BACKGROUND AND STUDY AIMS

Endoscopic minimally invasive treatment of internal hemorrhoids may cause postoperative pain. The aim of the study is to investigate the analgesic effect of lidocaine plus lauromacrogol on postoperative pain caused by endoscopic rubber band ligation (ERBL) combined with injection sclerotherapy (IS) for internal hemorrhoids treatment.

PATIENTS AND METHODS

Clinical data of grade Ⅲ internal hemorrhoids patients who underwent ERBL combined with IS in department of Digestive Medicine, Shenzhen Hospital of Southern Medical University, were retrospectively analyzed. According to difference in the composition of sclerosing solution, the patients were divided into control group (lauromacrogol group, 46 patients) and study group (lidocaine plus lauromacrogol group, 20 patients). Postoperative pain (quantized by Visual Analogue Scale, VAS), pain relief time and postoperative adverse reactions were compared. The therapeutic effect was followed up 1 month after operation.

RESULTS

VAS of postoperative pain was 0.80 ± 0.42 points and pain relief time was 0.90 ± 0.56 days in the study group, while VAS of postoperative pain was 4.11 ± 1.37 points and pain relief time was 2.57 ± 0.83 days in the control group, there was statistical difference between them (P < 0.05). There was no significant difference in the incidence of postoperative adverse reactions and follow-up therapeutic effect between the control group and the study group.

CONCLUSION

Lidocaine plus lauromacrogol is useful for pain alleviation on ERBL combined with IS for internal hemorrhoids treatment because of its convenient procedure, low adverse reaction incidence and good therapeutic effect, which is worthy of promotion.

Progress in Endoscopic Treatment of Hemorrhoids

Hemorrhoids are one of the most common diseases of the anorectal region. Previously, treatment for hemorrhoids included conservative treatment, outpatient treatment, and surgical treatment. The development of flexible reversible endoscopes has provided precise controllability and imaging, enabling further improvement and development of various endoscopic techniques to treat hemorrhoids. This article discusses several of these endoscopic techniques: rubber band ligation, sclerotherapy, and electrocoagulation. The development, efficacy, and advantages of these treatments are summarized and evaluated. It is expected that going forward, endoscopic technology will be further applied in clinical practice and may become the first-line method for the treatment of hemorrhoids.

ENDOSCOPIC BAND LIGATION FOR THE TREATMENT OF HEMORRHOIDAL DISEASE

ABSTRACT BACKGROUND: There are several therapeutic options for symptomatic hemorrhoids, from hygienic and dietary measures to conventional surgery. The best technique adopted for alternative and non-surgical treatment for intermediate grade (II and III) hemorrhoidal disease is rubber band ligation. More recently, the technique has been used with the aid of a gastroscope and a kit of elastic rubber bands for esophageal varices. This technique was called Endoscopic Rubber Band Ligation of hemorrhoids (ERBL). OBJECTIVE: The objective is Compare the results and the incidence of the immediate and late complications in patients undergoing ERBL. The satisfaction with the treatment of patients undergoing different number of rubber band ligatures were also analyzed. METHODS: This is a cohort study included patients undergoing ERBL from 2007 to 2014 at the hospital. The incidence of early and late complications and the satisfaction with the treatment of patients undergoing until two ligatures and patients undergoing three or more ligatures in the same procedure were compared. RESULTS: The study included 116 patients. The most frequently reported symptom was anal bleeding (n=72; 62.1%). The number of rubber band ligatures performed during the ERBL procedure varied from one to six; 84 (72,4%) patients had three or more rubber band ligatures performed during the procedure. No significant associations were observed between the incidence of early or late complications and satisfaction with ERBL among the group subjected until two rubber band ligatures or three or more rubber band ligatures. CONCLUSION: The endoscopic elastic ligation method proved to be a feasible, safe and efficient for the treatment of symptomatic hemorrhoidal disease grades II and III. The technique had moderate rates of immediate and late complications, but most of the complications are considered of low magnitude, easily resolved and without clinical repercussions, no matter how much ligations were performed in the same procedure.

Rubber band ligation of hemorrhoids: A guide for complications

Rubber band ligation is one of the most important, cost-effective and commonly used treatments for internal hemorrhoids. Different technical approaches were developed mainly to improve efficacy and safety. The technique can be employed using an endoscope with forward-view or retroflexion or without an endoscope, using a suction elastic band ligator or a forceps ligator. Single or multiple ligations can be performed in a single session. Local anaesthetic after ligation can also be used to reduce the post-procedure pain. Mild bleeding, pain, vaso-vagal symptoms, slippage of bands, priapism, difficulty in urination, anal fissure, and chronic longitudinal ulcers are normally considered minor complications, more frequently encountered. Massive bleeding, thrombosed hemorrhoids, severe pain, urinary retention needing catheterization, pelvic sepsis and death are uncommon major complications. Mild pain after rubber band ligation is the most common complication with a high frequency in some studies. Secondary bleeding normally occurs 10 to 14 d after banding and patients taking anti-platelet and/or anti-coagulant medication have a higher risk, with some reports of massive life-threatening haemorrhage. Several infectious complications have also been reported including pelvic sepsis, Fournier's gangrene, liver abscesses, tetanus and bacterial endocarditis. To date, seven deaths due to these infectious complications were described. Early recognition and immediate treatment of complications are fundamental for a favourable prognosis.

Multiple endoscopic methods are available to treat symptomatic internal hemorrhoids. Because of its low cost, ease of use, low rate of adverse events, and relative effectiveness, RBL is currently the most widely used technique.

Endoscopic band ligation: beyond prevention and management of gastroesophageal varices

Endoscopic band ligation (EBL) is the preferred endoscopic technique for the endoscopic treatment of acute esophageal variceal bleeding. EBL has also been used to treat nonvariceal bleeding. Recently, Han et al demonstrated that EBL can be a feasible and safe alternate technique for the management of iatrogenic gastric perforation especially in cases in which closure with endoclips is difficult. EBL is technically simpler to perform than other methods and provides a good view of the lesions under direct pressure and suction from the transparent ligation cap. EBL can be used even if the diameter of the perforation is greater than 10 mm or if there is a severe tangential angle. In this commentary, we discuss the efficacy and safety of EBL for the closure of iatrogenic gastrointestinal perforation. We also discuss the advantages and disadvantages of EBL for the treatment of nonvariceal bleeding.

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.

Long-term result after rubber band ligation for haemorrhoids

PURPOSE

Rubber band ligation (RBL) is a well-known and recognised outpatient procedure utilised for the treatment of symptomatic internal haemorrhoids. This paper describes a retrospective study which analyses the short- and long-term results of a personal series of patients.

MATERIALS AND METHODS

A consecutive group of 206 patients with symptomatic internal second- and third-degree haemorrhoids were treated with RBL as outpatients from 1982 to 1989. Two or three piles were legated in a single session. All patients were systematically visited after 1 month and 1 year. Respectively after 10 and 17 years, all the patients were contacted to obtain a telephone follow-up.

RESULTS

The short-term follow-up at 1 month and at 1 year showed that 46% of the patients experienced moderate anal pain for 24 h post procedure. Two patients had severe pain (1%) and were admitted in the hospital to be submitted to an operative haemorrhoidectomy within a few days. Only 2.4% of the patients experienced rectal bleeding after a week, and 20% had a second session of RBL after 1 month. At 1 year follow-up, 90% of the patients with second-degree piles and 75% of patients with third-degree piles reported no residual symptoms. The long-term telephone follow-up at 10 and 17 years collected the history of 138 patients (67%). A group of 69% was asymptomatic, 28% had residual symptoms, and 3% needed further surgery.

CONCLUSION

RBL is a safe and effective treatment for symptomatic internal haemorrhoids. Our long-term follow-up demonstrated good long-term results for internal second- and third-degree haemorrhoids.

Randomized prospective study of endoscopic rubber band ligation compared with bipolar coagulation for chronically bleeding internal hemorrhoids

OBJECTIVES

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.

METHODS

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.

RESULTS

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.

CONCLUSIONS

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.

Development of digestive endoscopic ligator and advances in application of ligation

Great progress has been made in the development of both endoscopic variceal ligator and ligation application in the past 20 years. In clinical practice, endoscopic variceal ligation (EVL) has been recognized as the first choice to treat esophageal variceal hemorrhage by the domestic and foreign experts because of its good efficacy as well as milder and fewer complications. The application category of endoscopic ligation has been expanded to other fields of digestive endoscopic therapy. Endoscopic ligation has become a simple and safe as well as generalized ligation technique with a high efficacy.

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.

Review article: the management of lower gastrointestinal bleeding

Several recent advances have been made in the evaluation and management of acute lower gastrointestinal bleeding. This review focuses on the management of lower gastrointestinal bleeding, especially acute severe bleeding. The aim of the study was to critically review the published literature on important management issues in lower gastrointestinal bleeding, including haemodynamic resuscitation, diagnostic evaluation, and endoscopic, radiologic, and surgical therapy, and to develop an algorithm for the management of lower gastrointestinal bleeding, based on this literature review. Publications pertaining to lower gastrointestinal bleeding were identified by searches of the MEDLINE database for the years 1966 to December 2004. Clinical trials and review articles were specifically identified, and their reference citation lists were searched for additional publications not identified in the database searches. Clinical trials and current clinical recommendations were assessed by using commonly applied criteria. Specific recommendations are made based on the evidence reviewed. Approximately, 200 original and review articles were reviewed and graded. There is a paucity of high-quality evidence to guide the management of lower gastrointestinal bleeding, and current endoscopic, radiologic, and surgical practices appear to reflect local expertise and availability of services. Endoscopic literature supports the role of urgent colonoscopy and therapy where possible. Radiology literature supports the role of angiography, especially after a positive bleeding scan has been obtained. Limited surgical data support the role of segmental resection in the management of persistent lower gastrointestinal bleeding after localization by either colonoscopy or angiography. There is limited high-quality research in the area of lower gastrointestinal bleeding. Recent advances have improved the endoscopic, radiologic and surgical management of this problem. However, treatment decisions are still often based on local expertise and preference. With increased access to urgent therapeutic endoscopy for the management of acute upper gastrointestinal bleeding, diagnostic and therapeutic colonoscopy can be expected to play an increasing role in the management of acute lower gastrointestinal bleeding.

Colonoscopic classification of internal hemorrhoids: usefulness in endoscopic band ligation

BACKGROUND

Bleeding is one of the main symptoms of internal hemorrhoids. However, the conventional Goligher's classification of internal hemorrhoids does not consider the severity of bleeding. We intended to establish a useful method for evaluating internal hemorrhoids using a colonoscope that reflected the severity of the symptoms.

METHODS

Using a colonoscope in the retroflexed and forward viewing position, 104 patients with symptomatic internal hemorrhoids were evaluated based on the criteria of range, form and red color signs (RCS). Range was determined by the circumferential distribution of internal hemorrhoids and scaled from 0 to 4. Form was determined by size and scaled from 0 to 2. The presence of RCS was also evaluated. Symptoms were determined by interview and scaled from 0 to 3. Patients were treated by endoscopic band ligation (EBL) and were examined endoscopically before and 4 weeks after the treatment.

RESULTS

Before the treatment, range, form and RCS were significantly correlated to bleeding (P < 0.01), and form was significantly correlated to prolapse (P < 0.05). The endoscopic classification scores at 4 weeks after EBL improved significantly (range from 3.25 +/- 0.05-0.56 +/- 0.08 [P < 0.01] and form from 2.81 +/- 0.04-0.56 +/- 0.07 P < 0.01).

CONCLUSION

The new endoscopic classification of internal hemorrhoids proved to be closely correlated to symptoms, particularly bleeding, and thus highly useful in evaluating the effectiveness of the treatment.

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.

Endoscopic Management of Lower Gastrointestinal Bleeding

Colonoscopy continues to be the primary tool for diagnostic evaluation and management of lower gastrointestinal bleeding (LGIB). With the advent of newer endoscopy delivery therapeutic modalities, the treatment of LGIB has changed dramatically over the decades. The most dramatic change has been the role of surgery, which has been substantially reduced due to the therapeutic colonoscopy. This article reviews recent advances in the endoscopic treatment options in LGIB of the colon and rectum.

Retroflexed endoscopic multiple band ligation of symptomatic internal hemorrhoids

BACKGROUND

Elastic band ligation is a well-established nonoperative method for treatment of internal hemorrhoids that give rise to symptoms. This study assessed the efficacy and safety of retroflexed endoscopic multiple band ligation, a procedure that involves extensive ligation of internal hemorrhoids, and the immediately proximal normal rectal mucosa, by means of a retroflexed endoscope.

METHODS

Eighty-two patients with symptoms caused by internal hemorrhoids (15, stage I; 19, stage II; 47, stage III; 1, stage IV) were treated by retroflexed endoscopic multiple band ligation. Symptoms (prolapse, bleeding, pain with defecation) were graded from 0 to 3. Range and form of the internal hemorrhoids were evaluated endoscopically. Retroflexed endoscopic multiple band ligation was performed by using a flexible endoscope with an attached band ligation device in the retroflexed position.

RESULTS

A mean of 8 bands (range 4-14) were placed per treatment session. Seventy-six patients were treated in a single session, 5 in two sessions, and one in 3 sessions. Symptom and endoscopic scores improved at 4 weeks after the retroflexed endoscopic multiple band ligation: bleeding, from 1.26 to 0.53 (p<0.01); prolapse, from 1.94 to 0.5 (p<0.01); pain, from 1.03 to 0.93 (p=0.67); Goligher classification, from 2.41 to 1.09 (p<0.01); range, from 3.25 to 0.56 (p<0.01); and form, from 2.81 to 0.56 (p<0.01). Long-term response (mean follow-up 12 months, range 3-40 months) was excellent for 89% of the patients, good for 9%, and poor for 2%. No major complication was noted.

CONCLUSIONS

Retroflexed endoscopic multiple band ligation is a safe and effective method for treatment for patients with symptoms caused by internal hemorrhoids.

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.

The role of sigmoidoscopy and colonoscopy in the diagnosis and management of lower gastrointestinal disorders: technique, indications, and contraindications

Flexible sigmoidoscopy and colonoscopy have revolutionized the clinical management of colonic diseases. Colonoscopy has a broad range of indications, including evaluating lower GI symptoms such as lower GI bleeding, evaluating abnormal radiographic findings, and screening and surveillance for colon cancer. Colonoscopy is increasingly being used therapeutically. Patient evaluation, patient instructions, and colonic preparation before colonoscopy are essential for safe and efficient colonoscopy. Intravenous sedation reduces patient pain and anxiety during colonoscopy, but requires monitoring by pulse oximetry and automated measurements of vital signs. An experienced colonoscopist can complete colonoscopy in 90% or more of cases, using maneuvers to maintain the colonic lumen in view, straighten the colonoscope, and avoid looping during colonic intubation.

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.

Endoscopic treatment of lower gastrointestinal bleeding

Urgent colonoscopy has emerged as the initial diagnostic and main therapeutic tool in the evaluation and treatment of colonic lower gastrointestinal bleeding. Endoscopic therapy can effectively treat most cases of colonic bleeding with a demonstrable improvement in clinical outcome parameters. The identification of high-risk stigmata of hemorrhage enables selective targeting of endoscopic therapy to lesions at high risk of rebleeding. Advances in technologies such as novel mechanical methods of hemostasis (eg, metallic clips), injection techniques (eg, cyanoacrylate injection), and the widening application of established endoscopic hemostatic techniques (eg, rubber-band ligation) to colonic lesions offers the possibility of further improvements in the efficacy of endoscopic hemostasis. Clinical trials are needed to compare these novel endoscopic techniques with more conventional approaches to establish the best form of endoscopic therapy for different bleeding lesions and finally to establish more definitively the optimal timing of colonoscopy.

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

OBJECTIVE

We evaluated a technique of hemorrhoid banding using videoscopic anoscopy and a single-handed ligator that offers substantial cost savings over endoscope-mounted devices.

METHODS

Patients with rectal bleeding from grade II/III hemorrhoids had videoscopic anoscopy, which provided a magnified view, allowing accurate localization of the hemorrhoids and the dentate line before banding, and a photographic record, if required. Banding was performed using a suction ligator that could be operated by one hand, allowing the other to control the anoscope.

RESULTS

Of 39 patients with second- and third-degree hemorrhoids, 34 (87%) had no further bleeding after a single banding session and a further three had no recurrence after a second session. The only complications were pain (one patient) and infection (one patient).

CONCLUSIONS

This method is convenient and effective, costing per procedure less than one-tenth of endoscope-mounted band ligators. We recommend its use in preference if magnified views and a photographic record are required. However, its cost and complexity, compared with traditional hemorrhoid banding, may mean that the latter is preferred in the office setting.

Anorectal Disease

Most symptomatic internal hemorrhoids, grade 1 through 3, can be treated successfully with office-based procedures. Anorectal suppurative diseases must be treated surgically. Control of sepsis with subsequent fistula surgery as necessary is the goal. New nonoperative methods of anal fissure therapy are directed at reducing anal sphincter pressures. These methods have shown significant reduction in the need for sphincterotomy--a proven surgical technique with some risk of impaired continence. Surgery, using an advancement flap and partial internal sphincterotomy, remains the primary treatment for anal stenosis. Solitary rectal ulcer remains a difficult problem to manage medically and surgically. Multiple surgical techniques can effectively treat rectal prolapse. A minimal technique using Silastic wrap (Wright Medical Technologies; Arlington, TX), perineal resection (Altemeier procedure), and sigmoidectomy-rectopexy, or Ripstein suspension, has been the most favored method in selected patients.
