Endoscopic polidocanol foam sclerobanding for the treatment of grade Ⅱ-Ⅲ internal hemorrhoids:A prospective,multi-center,randomized study

BACKGROUND Endoscopic rubber band ligation(ERBL)is a nonsurgical technique for the treatment of symptomatic internal hemorrhoids but is limited by recurrence and post-procedural pain.AIM To evaluate satisfaction,long-term recurrence,and post-procedural pain in managing internal hemorrhoids using a combination of polidocanol foam sclerotherapy and ERBL.METHODS This was a prospective,multicenter,randomized study.A total of 195 consecutive patients diagnosed with grade II-III internal hemorrhoids were enrolled from four tertiary hospitals and randomly divided into a cap-assisted endoscopic polidocanol foam sclerobanding(EFSB)or an ERBL group.All patients were followed-up for 12 months.Symptom-based severity and post-procedural pain were assessed using a hemorrhoid severity score(HSS)and a visual analog scale(VAS).Continuous variables were reported as medians and interquartile range.RESULTS One hundred and ninety-five patients were enrolled,with 98 in the EFSB group.HSS was lower in the EFSB group than in the ERBL group at 8 weeks[4.0(3.0-5.0)vs 5.0(4.0-6.0),P=0.003]and 12-month[2.0(1.0-3.0)vs 3.0(2.0-3.0),P<0.001]of follow-up.The prolapse recurrence rate was lower in the EFSB group at 12 months(11.2%vs 21.6%,P=0.038).Multiple linear regression analysis demonstrated that EFSB treatment[B=-0.915,95%confidence interval(CI):−1.301 to−0.530,P=0.001]and rubber band number(B=0.843,95%CI:0.595-1.092,P<0.001)were negatively and independently associated with the VAS score 24 hours post-procedure.The median VAS was lower in the EFSB group than in the ERBL[2.0(1.0-3.0)vs 3.0(2.0-4.0),P<0.001].CONCLUSION Cap-assisted EFSB provided long-term satisfaction and effective relief from the recurrence of prolapse and pain 24 hours post-procedure.

Analysis of factors impacting postoperative pain and quality of life in patients with mixed hemorrhoids:A retrospective study

BACKGROUND Hemorrhoids are among the most common and frequently encountered chronic anorectal diseases in anorectal surgery.They are venous clusters formed by con-gestion,expansion,and flexion of the venous plexus in the lower part of the rec-tum.Mixed hemorrhoids bleed easily and recurrently,and this can result in severe anemia.Hence,they may have a negative effect on the health of the patient and surgical treatment is required.Milligan-Morgan hemorrhoidectomy has been widely used since 1937 for the treatment of grade III and IV hemorrhoids.How-ever,most patients experience different degrees of postoperative pain that may cause anxiety.with mixed hemorrhoids post-surgery.METHODS The clinical data of patients with mixed hemorrhoids who underwent Milligan-Morgan hemorrhoidectomy were collected retrospectively.The basic character-istics of the enrolled patients with mixed hemorrhoids were recorded,and based on the Goligher clinical grading system,the hemorrhoids were classified as grades III or IV.The endpoint of this study was the disappearance of pain in all patients.Quantitative data were presented as mean±SD,such as age,pain score,and QoL score.Student’s t-test was used to compare the groups.RESULTS A total of 164 patients were enrolled.The distribution of the visual analog scale pain scores of all patients at 3,7,14 and 28 d after surgery showed that post-surgery pain was significantly reduced with the passage of time.Fourteen days after the operation,the pain had completely disappeared in some patients.Twenty-eight days after the surgery,none of the patients experienced any pain.Comparing the World Health Or-ganization Quality of Life-BREF self-reporting questionnaire scores of patients between 14 and 28 d after surgery,we observed that the quality-of-life scores of the patients post-surgery had significantly improved.There were six items that were compared at 14-and 28-d post-surgery.The mean QoL score 28 d after surgery(4.79±0.46)was higher than that at 14 d post-surgery(3.79±0.57).The mean health condition score 28 d after surgery(4.80±0.41)was also higher than that at 14 d post-surgery(4.01±0.62).The mean physical health score 28 d after surgery(32.10±2.96)was significantly higher than that at 14 d post-surgery(23.41±2.85).The mean psychological health score 28 d after surgery(27.22±1.62)was significantly higher than that at 14 d post-surgery(21.37±1.70).The mean social relations score 28 d after surgery(12.21±1.59)was significantly higher than that at 14 d post-surgery(6.32±1.66).The mean surrounding environment score 28 d after surgery(37.13±2.88)was significantly higher than that at 14 d post-surgery(28.42±2.86).The differences in quality-of-life scores at day 14 and day 28 post-surgery were ob-served to be statistically significant(P<0.001).CONCLUSION Milligan-Morgan hemorrhoidectomy can significantly improve the postoperative QoL of patients.Age,sex,and the number of surgical resections were important factors influencing Milligan-Morgan hemorrhoidectomy.

Does hemorrhoidal artery embolization really benefit patients with hemorrhoids?

This letter offers commentary on an article published in a recent issue of the World Journal of Gastroenterology.Hemorrhoidal artery embolization is a promising approach to severe hemorrhoidal bleeding treatment,but inappropriate patient selection and the use of different embolization procedures may affect the clinical efficacy and cause serious complications.In this article,the most appropriate candidate patients,embolization materials,embolization methods,and clinical evaluation methods are discussed to improve the safety and effectiveness of the procedure.

Endoscopic polidocanol foam sclerobanding for treatment of internal hemorrhoids:A novel outpatient procedure

In the study,we comment on the article by Qu et al.Internal hemorrhoids are the most common anorectal disorders worldwide with bleeding,prolapse,and difficulty in defecation.Endoscopic rubber band ligation(ERBL)is a safe,convenient,quick,and economical outpatient procedure.The main goal of ERBL is to alleviate prolapse,but the high incidence of recurrence and post-procedural pain are of clinical concern.Polidocanol foam as a local hemostatic and anesthetic agent could reduce the rates of post-procedural pain and bleeding.Endoscopic polidocanol foam sclerobanding(EFSB)is a novel approach that could lift the mucosa for easy ligation and promote increased scarring in the submucosal tissue which translates into long-term relief from prolapse recurrence and reduced 24-h postprocedural pain.The study by Qu et al is a novel multi-center prospective randomized study to compare ERBL and EFSB in patients with grades II and III internal hemorrhoids with one-year follow-up.Results showed that EFSB is a novel therapy for internal hemorrhoids,but future studies with a larger sample,multiple treatment sessions,and long-term follow-up are required to confirm these findings.

Endoscopic polidocanol foam sclerobanding for the treatment of Grade Ⅱ-Ⅲ internal hemorrhoids:The focus of clinical practice

We have read the article by Qu et al with great interest,as it presents an inte-gration of endoscopic polidocanol foam sclerotherapy with rubber band ligation in patients with Grade Ⅱ-Ⅲ internal hemorrhoids.The authors conducted a prospective,multicenter,randomized study to evaluate the long-term sympto-matic and endoscopic efficacy of this combined intervention.In this discussion,we focus on the procedural steps of this combined strategy and suggest potential avenues for future research.

Rectal varices vs hemorrhoids-diagnosis and management

Rectal varices are an uncommon manifestation of portal hypertension.Although hemorrhoids can be seen in cirrhotic patients,distinguishing between rectal varices and hemorrhoids can be challenging.Furthermore,the underlying mechanism and treatment options vary.Hence,the correct identification is of utmost important.Through this letter,we highlight the features of both and listed the distinguishing points between the two etiologies.

Clinical Observation of Chinese Medicinal Prescriptions for Swelling and Pain in The Postoperative Treatment of Mixed Hemorrhoids

Objective:To observe the clinical effect of traditional Chinese medicine(TCM)on reducing swelling and pain in patients with mixed hemorrhoids.Methods:Sixty patients with mixed hemorrhoids who were admitted to the Hospital of Traditional Chinese Medicine of Qiqihar from January 2023 to January 2024 were selected and divided into two groups.The treatment group(n=30)was treated with mixed hemorrhoid ligation combined with traditional Chinese swelling and pain medicine,and the control group(n=30)was only treated with mixed hemorrhoid ligation.The pain level,edema score,and prognosis of the two groups after the intervention were analyzed.The clinical efficacy was used as the evaluation criterion to compare the clinical effects of different treatment options.Results:After the treatment,the pain score,edema score,and prognostic wound score of the treatment group were all lower than those of the control group(P 0.05).The total clinical effectiveness of the treatment group(100%)was higher than that of the control group(76.67%),(χ^(2)=4.2857,P<0.05).Conclusion:The application of traditional Chinese swelling and pain medicine in treating patients with mixed hemorrhoids effectively reduced the patient’s pain,reduced the degree of wound edema,promoted wound healing,and improved the patient’s prognosis.The curative effect was significant and had a positive impact.

Transanal eco-Doppler evaluation after hemorrhoidal artery embolization

BACKGROUND Hemorrhoidal artery embolization(Emborrhoid)is a novel method for the treatment of severe hemorrhoidal bleeding.Despite having a technical success rate of 93%-100%,the clinical success ranges between 63%and 94%,with a rebleeding rate of 13.6%.AIM To evaluate the effectiveness of this procedure in reducing hemorrhoidal flow and hemorrhoidal bleeding.METHODS This prospective observational pilot study was conducted at Division of General Surgery 1 and Tertiary Referral Pelvic Floor Center,Treviso Regional Hospital,Italy.In a 2 months period(February-March 2022),consecutive patients with hemorrhoidal bleeding scores(HBSs)≥4,Goligher scores of II or III,failure of non-operative management,and a candidate for Emborrhoid were included.Endoanal ultrasound with eco-Doppler was performed preoperatively and 1 month after the procedure.The primary endpoint was to quantify the changes in arterial hemorrhoidal flow after treatment.The secondary endpoint was to evaluate the correlation between the flow changes and the HBS.RESULTS Eleven patients underwent Emborrhoid.The overall pretreatment mean systolic peak(MSP)was 14.66 cm/s.The highest MSP values were found in the anterior left lateral(17.82 cm/s at 1 o’clock and 15.88 cm/s at 3 o’clock)and in the posterior right lateral(14.62 cm/s at 7 o’clock and 16.71 cm/s at 9 o’clock)quadrants of the anal canal.After treatment,the overall MSP values were significantly reduced(P=0.008)although the correlation between MSP and HBS changes was weak(P=0.570).A statistical difference was found between distal embolization compared with proximal embolization(P=0.047).However,the coil landing zone was not related to symptoms improvement(P=1.000).A significant difference in MSP changes was also reported between patients with type 1 and type 2 superior rectal artery(SRA)anatomy(P=0.040).No relationship between hemorrhoidal grades(P=1.000),SRA anatomy(P=1.000)and treatment outcomes was found.CONCLUSION The preliminary findings of this pilot study confirm that Emborrhoid was effective in reducing the arterial hemorrhoidal flow in hemorrhoidal disease.However,the correlation between the post-operative MSP and HBS changes was weak.Hemorrhoidal grade,SRA anatomy and type of embolization were not related to treatment outcomes.

Comparison of external treatment of Acupuncture and moxibustion and intervention of Chinese and Western Medicine on postoperative pain of hemorrhoids:A systematic review and meta-analysis

Background To evaluate the clinical efficacy and safety of acupuncture and moxibustion in the treatment of postoperative pain of hemorrhoids compared with traditional Chinese medicine and western medicine.Methods CNKI,PubMed,Cochrane Library,Science Direct,Wan Fang,VIP,CBM,WOS,Bailian Yun Library and other databases were systematically retrieved from January 1,2017 to October 31,2022 for clinical randomized controlled trials of acupuncture versus traditional Chinese medicine and Western medicine for postoperative pain in hemorrhoids.The two evaluators independently retrieved,sifted through literature and extracted data for inclusion in a randomized controlled trial of acupuncture for the treatment of hemorrhoid pain that matched the study.Literature quality assessment was performed using RevMan5.4 for meta-analysis.Results A total of 540 related literature articles were retrieved,of which 139 were from CNKI,104 from Wan Fang,26 from VIP,7 from PubMed,9 from Cochrane Library,35 from WOS,173 from CMB,1 from Science Direct and 46 from the Bailian Yun Library,Screening resulted in inclusion of 10 RCTs including 870 patients.Meta analysis showed no statistically significant difference between the degree of pain in 2 hours[MD=-0.01,95%CI(-0.23,0.24),P=0.95].And it showed that the total effective rate of the two groups was[RR=1.14,95%CI(1.06,1.24),P=0.001],intervention for 2 days pain degree was[MD=0.41,95%CI(0.13,0.69),P=0.004],the length of hospital stay was[SMD=1.10,95%CI(0.73,1.48),P<0.00001],the incidence of adverse reaction was[RR=0.15,95%CI(0.03,0.79),P=0.03],the difference was statistically significant(P<0.05).Conclusion Drug treatment is effective quickly,analgesia effect is better than acupuncture in early treatment,but the effect is not lasting.Acupuncture treatment is slow to start but the effects of acupuncture will gradually become apparent at a later stage.However,due to the poor quality of collection,multicenter,large sample size and double-blind randomized controlled trials are still needed.

Redefining hemorrhoid therapy with endoscopic polidocanol foam sclerobanding

Hemorrhoids are a common and painful condition,with conventional treatments such as endoscopic rubber band ligation(ERBL)and injection sclerotherapy often falling short due to high recurrence rates and significant post-operative pain.A clinical trial by Qu et al introduces a novel approach called endoscopic polidocanol foam sclerobanding(EFSB).This multicenter randomized trial involved 195 patients with grade II and III internal hemorrhoids and demonstrated that EFSB significantly reduced recurrence rates and post-procedural pain while improving symptom relief and patient satisfaction compared to ERBL.The study's strengths include its robust design,comprehensive outcome evaluation,and patient-centered approach.Despite limitations such as the single-blind design and relatively short follow-up period,the findings suggest that EFSB could enhance clinical practice by offering a more effective and patient-friendly treatment option.Further research is needed to validate these results and explore the long-term benefits and cost-effectiveness of EFSB.

Study of Hemorrhoid Disease in the Department of General Surgery of the Cs Ref of the Commune I Bamako

This work was a retrospective prospective study carried out in the general surgery department of the Cs ref of commune I from January 2009 to December 2012. Our study aimed to determine the hospital frequency of hemorrhoidal disease, to identify the contributing factors, describe the clinical and therapeutic aspects and analyze the surgical consequences. We collected 73 patients with an average age of 37.8 years (range: 19 years and 77 years) with a sex ratio of 2.5 in favor of men. We operated on 49 patients or 67.1% of cases. 71.2% of our patients were married and lived in Bamako. Schoolchildren and middle managers made up 39.8% of cases. 82.2% of patients were seen in ordinary consultation and 69.9% complained of progressive anal pain in 66.7% of cases. This pain was triggered by defecation in 88.2% of our patients. The contributing factors were dominated by constipation (53.4%), working in a seated position (41.1%) and a sedentary lifestyle (16.4%) of cases. Stage IV external hemorrhoids and hemorrhoidal thrombosis represented 53.8% of surgical indications. The most used surgical technique was that of Milligan-Morgan, i.e. 51.9% of cases and 45.2% of patients treated medically received a combination of transit regulator, venotonics and analgesics. The surgical aftermath was marked by hemorrhage (3 cases), delayed healing (5 cases), urinary retention (1 case) and scarring anal stenosis (1 case). The morbidity rate was 5.48% of cases and a zero mortality rate. The average length of hospitalization was 2 days with extremes of 1 and 5 days.

Surgical Treatment of Hemorrhoidal Disease at Brazzaville University Hospital Center

Introduction: Hemorrhoidal disease is a common pathology and its surgical treatment is based, among other things, on pedicular resection after failure of medical and instrumental treatment. The aim of this study is to analyze the epidemiological, clinical, therapeutic and evolving aspects of hemorrhoidal disease at the stage of surgical treatment at the University Hospital Center of Brazzaville. Patients and Methods: We conducted a retrospective and descriptive study carried out from January 2020 to December 2021, a 24 months period, in the Digestive surgery department of the University Hospital Center of Brazzaville. It concerned patients who underwent a surgical procedure for hemorrhoidal disease. Results: 21 cases were collected, representing a hospital frequency of 2.3%, with a sex ratio of 4.3 in favor of men. The average age of patients was 42.2 ± 11.9 years. The symptoms were mainly proctalgia, mass sensation and rectal bleeding. We recorded five cases (19.1%) of hemorrhoidal thrombosis and 16 cases (80.9%) of hemorrhoidal prolapse including 12 cases requiring manual integration (Goligher grade III) and four irreducible permanent cases (Goligher grade IV). The Grade III prolapse was associated with a polyp in one patient and with posterior anal fissure in another patient. Out of the 21 patients, 14 underwent a tripedicular hemorrhoidectomy according to Milligan and Morgan. Two patients underwent mono- and bipedicular hemorrhoidectomy with resection of associated lesions and five patients underwent emergency thrombectomy. The outcome was favorable for all our patients. The average length of hospital stay was 1.5 ± 2.1 days. Conclusion: In the event of failure of medical and instrumental treatment, the hemorrhoidal cure according to Milligan and Morgan is the surgical treatment of reference for hemorrhoidal disease at the University Hospital Center of Brazzaville.

Modified stapled hemorrhoidopexy for lower postoperative stenosis: A five-year experience

BACKGROUND Stapled hemorrhoidopexy(SH)is currently a widely accepted method for treating the prolapse of internal hemorrhoids.Postoperative anal stenosis is a critical complication of SH.A remedy for this involves the removal of the circumferential staples of the anastomosis,followed by the creation of a hand-sewn anastomosis.Numerous studies have reported modified SH procedures to improve outcomes.We hypothesized that our modified SH technique may help reduce complications of anal stenosis after SH.AIM To compare outcomes of staple removal at the 3-and 9-o’clock positions during modified SH in patients with mixed hemorrhoids.METHODS This was a single-center,retrospective,observational study.Patients with grade III or IV hemorrhoids who underwent standard or modified SH at our colorectal center between January 1,2015,and January 1,2020,were included.The operation time,blood loss,length of hospital stay,and incidence of minor or major complic-ations were recorded.RESULTS Patients with grade III or IV hemorrhoids who underwent standard or modified SH at our colorectal center between January 1,2015 and January 1,2020,were included.Operation time,blood loss,length of hospital stay,and incidence of minor or major complications were recorded.We investigated 187 patients(mean age,50.9 years)who had undergone our modified SH and 313 patients(mean age,53.0 years)who had undergone standard SH.In the modified SH group,54%of patients had previously undergone surgical intervention for hemorrhoids,compared with the 40.3%of patients in the standard SH group.The modified SH group included five(2.7%)patients with anal stenosis,while 21(6.7%)patients in the standard SH group had complications of anal stenosis.There was a significant relationship between the rate of postoperative anal stenosis and the modified SH:0.251(0.085-0.741)and 0.211(0.069-0.641)in multiple regression analysis.The modified SH technique is a safe surgical method for advanced grade hemorrhoids and might result in a lower rate of postoperative anal stenosis than standard SH.CONCLUSION The modified SH technique is a safe surgical method for advanced grade hemorrhoids and might result in a lower rate of postoperative anal stenosis than standard SH.

Treatment of hemorrhoids: A coloproctologist's view

Hemorrhoids is recognized as one of the most common medical conditions in general population. It is clinically characterized by painless rectal bleeding during defecation with or without prolapsing anal tissue. Generally,hemorrhoids can be divided into two types: internal hemorrhoid and external hemorrhoid. External hemorrhoid usually requires no specific treatment unless it becomes acutely thrombosed or causes patients discomfort. Meanwhile,low-graded internal hemorrhoids can be effectively treated with medication and nonoperative measures(such as rubber band ligation and injection sclerotherapy). Surgery is indicated for highgraded internal hemorrhoids,or when non-operative approaches have failed,or complications have occurred. Although excisional hemorrhoidectomy remains the mainstay operation for advanced hemorrhoids and complicated hemorrhoids,several minimally invasive operations(including Ligasure hemorrhoidectomy,doppler-guided hemorrhoidal artery ligation and stapled hemorrhoidopexy) have been introduced into surgical practices in order to avoid post-hemorrhiodectomy pain. This article deals with some fundamental knowledge and current treatment of hemorrhoids in a view of a coloproctologist- which includes the management of hemorrhoids in complicated situations such as hemorrhoids in pregnancy,hemorrhoids in immunocompromised patients,hemorrhoids in patients with cirrhosis or portal hypertension,hemorrhoids in patients having antithrombotic agents,and acutely thrombosed or strangulated hemorrhoids. Future perspectives in the treatment of hemorrhoids are also discussed.

Milligan-Morgan hemorrhoidectomy with anal cushion suspension and partial internal sphincter resection for circumferential mixed hemorrhoids

AIM:To identify a more effective treatment protocol for circumferential mixed hemorrhoids.METHODS:A total of 192 patients with circumferential mixed hemorrhoids were randomized into the treatment group,where they underwent Milligan-Morgan hemorrhoidectomy with anal cushion suspension and partial internal sphincter resection,or the control group,where traditional external dissection and internal ligation were performed.Postoperative recovery and complications were monitored.RESULTS:The time to wound healing was 12.96 ± 2.25 d in the treatment group shorter than 19.58 ± 2.71 d in the control group.Slight pain rate was 58.3% in the treatment group higher than 22.9% in the control group;moderate pain rate was 33.3% in the treatment group lower than 56.3% in the control group severe pain rate was 8.4% in the treatment group lower than 20.8% in the control group.No edema rate was 70.8% in the treatment group higher than 43.8% in the control group;mild local edema rate was 26% in the treatment group lower than 39.6% in the control group obvious local edema was 3.03% in the treatment group lower than 16.7% in the control group.No stenosis rate was 85.4% in the treatment group higher than 63.5% in the control group;moderate stenosis rate was 14.6% in the treatment group Lower than 27.1% in the control group severe anal stenosis rate was 0% in the treatment group lower than 9.4% in the control group.CONCLUSION:Milligan-Morgan hemorrhoidectomy with anal cushion suspension and partial internal sphincter resection is the optimal treatment for circumferential mixed hemorrhoids and can be widely applied in clinical settings.

Cap-assisted endoscopic sclerotherapy for hemorrhoids: Methods, feasibility and efficacy

AIM: To evaluate the methodology, feasibility, safety and efficacy of a novel method called cap-assisted endoscopic sclerotherapy(CAES) for internal hemorrhoids.METHODS: A pilot study on CAES for grade Ⅰ to Ⅲ internal hemorrhoids was performed. Colon and terminal ileum examination by colonoscopy was performed for all patients before starting CAES. Polypectomy and excision of anal papilla fibroma were performed if polyps or anal papilla fibroma were found and assessed to be suitable for resection under endoscopy. CAES was performed based on the requirement of the cap, endoscope, disposable endoscopic long injection needle, enough insufflated air and sclerosing agent.RESULTS: A total of 30 patients with grade Ⅰ to Ⅲ internal hemorrhoids was included. The follow-up was more than four weeks. No bleeding was observed after CAES. One(3.33%) patient claimed mild tenesmus within four days after CAES in that an endoscopist performed this procedure for the first time. One hundred percent of patients were satisfied with this novel procedure, especially for those patients who underwent CAES in conjunction with polypectomy or excision of anal papilla fibroma.CONCLUSION: CAES as a novel endoscopic sclerotherapy should be a convenient, safe and effective flexible endoscopic therapy for internal hemorrhoids.

Procedure for prolapse and hemorrhoids vs traditional surgery for outlet obstructive constipation

AIM: To compare the clinical efficacies of two surgical procedures for hemorrhoid rectal prolapse with outlet obstruction-induced constipation.METHODS: One hundred eight inpatients who underwent surgery for outlet obstructive constipation caused by internal rectal prolapse and circumferential hemorrhoids at the First Affiliated Hospital of Xinjiang Medical University from June 2012 to June 2013 were prospectively included in the study.The patients with rectal prolapse hemorrhoids with outlet obstructioninduced constipation were randomly divided into two groups to undergo either a procedure for prolapse and hemorrhoids(PPH)(n = 54) or conventional surgery(n = 54; control group).Short-term(operative time,postoperative hospital stay,postoperative urinary retention,postoperative perianal edema,and postoperative pain) and long-term(postoperative anal stenosis,postoperative sensory anal incontinence,postoperative recurrence,and postoperative difficulty in defecation) clinical effects were compared between the two groups.The short- and long-term efficacies of the two procedures were determined.RESULTS: In terms of short-term clinical effects,operative time and postoperative hospital stay were significantly shorter in the PPH group than in the control group(24.36 ± 5.16 min vs 44.27 ± 6.57 min,2.1 ± 1.4 d vs 3.6 ± 2.3 d,both P < 0.01).The incidence of postoperative urinary retention was higher in the PPH group than in the control group,but the difference was not statistically significant(48.15% vs 37.04%).Theincidence of perianal edema was significantly lower in the PPH group(11.11% vs 42.60%,P < 0.05).The visual analogue scale scores at 24 h after surgery,first defecation,and one week after surgery were significantly lower in the PPH group(2.9 ± 0.9 vs 8.3 ± 1.1,2.0 ± 0.5 vs 6.5 ± 0.8,and 1.7 ± 0.5 vs 5.0 ± 0.7,respectively,all P < 0.01).With regard to long-term clinical effects,the incidence of anal stenosis was lower in the PPH group than in the control group,but the difference was not significant(1.85% vs 5.56%).The incidence of sensory anal incontinence was significantly lower in the PPH group(3.70% vs 12.96%,P < 0.05).The incidences of recurrent internal rectal prolapse and difficulty in defecation were lower in the PPH group than in the control group,but the differences were not significant(11.11% vs 16.67% and 12.96% vs 24.07%,respectively).CONCLUSION: PPH is superior to the traditional surgery in the management of outlet obstructive constipation caused by internal rectal prolapse with circumferential hemorrhoids.

Rubber band ligation of hemorrhoids: A guide for complications

Rubber band ligation is one of the most important, costeffective 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, vasovagal 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.

Treatment of hemorrhoids: A survey of surgical practice in Australia and New Zealand

BACKGROUND Hemorrhoidal disease is the most common anorectal disorder.Hemorrhoids can be classified as external or internal,according to their relation to the dentate line.External hemorrhoids originate below the dentate line and are managed conservatively unless the patient cannot keep the perianal region clean,or they cause significant discomfort.Internal hemorrhoids originate above the dentate line and can be managed according to the graded degree of prolapse,as described by Goligher.Generally,low-grade internal hemorrhoids are effectively treated conservatively,by non-operative measures,while high-grade internal hemorrhoids warrant procedural intervention.AIM To determine the application of clinical practice guidelines for the current management of hemorrhoids and colorectal surgeon consensus in Australia and New Zealand.METHODS An online survey was distributed to 206 colorectal surgeons in Australia and New Zealand using 17 guideline-based hypothetical clinical scenarios.RESULTS There were 82 respondents(40%)to 17 guideline-based scenarios.Nine(53%)reached consensus,of which only 1(6%)disagreed with the guidelines.This was based on low quality evidence for the management of acutely thrombosed external hemorrhoids.There were 8 scenarios which showed community equipoise(47%)and they were equally divided for agreeing or disagreeing with the guidelines.These topics were based on low and moderate levels of evidence.They included the initial management of grade I internal hemorrhoids,grade III internal hemorrhoids when initial management had failed and the patient had recognised risks factors for septic complications;and finally,the decision-making when considering patient preferences,including a prompt return to work,or minimal post-operative pain.CONCLUSION Although there are areas of consensus in the management of hemorrhoids,there are many areas of community equipoise which would benefit from further research.

Feasibility and safety of endoscopic submucosal dissection for lower rectal tumors with hemorrhoids

AIM: To evaluate the feasibility and safety of endoscopic submucosal dissection(ESD) for lower rectal lesions with hemorrhoids.METHODS: The outcome of ESD for 23 lesions with hemorrhoids(hemorrhoid group) was compared with that of 48 lesions without hemorrhoids extending to the dentate line(non-hemorrhoid group) during the same study period. RESULTS: Median operation times(ranges) in the hemorrhoid and non-hemorrhoid groups were 121(51-390) and 130(28-540) min. The en bloc resection rate and the curative resection rate in the hemorrhoid group were 96% and 83%, and they were 100% and 90% in the non-hemorrhoid group, respectively. In terms of adverse events, perforation and postoperative bleeding did not occur in both groups. In terms of the clinical course of hemorrhoids after ESD, the rate of complete recovery of hemorrhoids after ESD in lesions with resection of more than 90% was significantly higher than that in lesions with resection of less than 90%.CONCLUSION: ESD on lower rectal lesions with hemorrhoids could be performed safely, similarly to that on rectal lesions extending to the dentate line without hemorrhoids. In addition, all hemorrhoids after ESD improved to various degrees, depending on the resection range.
