Haemorrhoids: an update on management

Causal association between adiposity and hemorrhoids: a Mendelian randomization study

Background

Hemorrhoids are a very common anorectal disorder affecting a large number of individuals throughout the world. This study aimed to evaluate the causal effects of four adiposity traits including body mass index (BMI), body fat percentage, waist circumference, and waist-to-hip ratio on hemorrhoids by Mendelian randomization (MR).

Methods

We used summary statistics of BMI (N = 461,460), body fat percentage (N = 454,633), waist circumference (N = 462,166), waist-to-hip ratio (N = 212,244), and hemorrhoids (N = 337,199) from large-scale genome wide association studies of European ancestry. Univariable and multivariable MR were carried out to infer causality. The MR Steiger directionality test was used to test the causal direction.

Results

The primary MR analysis using the inverse variance weighted (IVW) method showed that there were positive effects of genetically determined BMI [odds ratio (OR) = 1.005, 95% confidence interval (CI): 1.003-1.008, per standard deviation (SD), p = 7.801 × 10-5], body fat percentage (OR = 1.005, 95% CI: 1.001-1.008, per SD, p = 0.008), waist circumference (OR = 1.008, 95% CI: 1.005-1.011, per SD, p = 1.051 × 10-6), and waist-to-hip ratio (OR = 1.010, 95% CI: 1.003-1.017, per SD, p = 0.003) on hemorrhoids. These findings were robust in multivariable MR adjusting for physical activity. The Steiger directionality test showed evidence against reverse causation.

Conclusion

Our MR study supports a causal role of adiposity in the development of hemorrhoids. Adiposity prevention may be an important strategy for reducing hemorrhoids risk.

ENSEAL® Hemorrhoidectomy, a Novel Technique, Versus Conventional Open Method for the Management of Grade III and IV Hemorrhoids

Background

Surgical removal of hemorrhoids is the gold-standard treatment for symptomatic grade III and IV hemorrhoid disease. There are numerous ways the hemorrhoidectomy surgical procedure is done but the most effective and least painful way is still to be elucidated.

Objective

To compare the outcomes of ENSEAL® (Ethicon, Inc., Raritan, USA) versus gold standard Milligan-Morgan hemorrhoidectomy in patients presenting with grade-III and IV hemorrhoids

Materials and methods

After ethical approval, the Randomized Controlled Trial was conducted at the Department of Surgery, Unit III, Lahore General Hospital, Lahore, Pakistan, between January 2020 and January 2022. In this study, 140 patients who met the inclusion criteria were recruited after informed consent. Patients were split randomly into two equal groups using a lottery technique. In group A, hemorrhoidectomy was carried out with ENSEAL®, whereas in group B, open hemorrhoidectomy was performed by the Milligan-Morgan method. the surgery duration and blood loss were noted. After the operation, patients were transferred to and discharged from the post-anesthesia recovery room. Patients were further followed up for pain scores after 24 hours. Data was analyzed by using Statistical Package for Social Sciences (SPSS) v25 (IBM Corp., Armonk, USA). Data was categorized for age, gender, body mass index (BMI), degree of hemorrhoids, and duration of hemorrhoids. A p-value <0.05 was considered significant.

Results

140 patients were included in this study. Group A patients underwent ENSEAL® hemorrhoidectomy, and group B was formed from those who underwent the Milligan-Morgan procedure. In group A, there were 41 (58.5%) males and 29 (41.4%) females, while in group B, there were 43 (61.4%) males and 27 (38.5%) females. The mean age of group A patients was 49.97 ± 7.36 years and 43.2 ± 8.01 years in group B. In group A, the mean operative time was 20.87 ± 3.05 min, while 27.10 ± 3.42 min in group B, which is statistically significant with a p-value of <0.001. In group A, mean blood loss was 9.79 ± 2.87 ml, while 13.36 ± 3.73 ml in group B, which is statistically significant with a p-value of <0.001. In group A, the mean pain score was 2.7 ± 1.08, while 3.34 ± 1.16 in group B, which is statistically significant with a p-value of <0.001.

Conclusion

When considering the length of the procedure and blood loss, ENSEAL® hemorrhoidectomy has been determined to be an effective treatment that the patients tolerated well. Therefore, ENSEAL® hemorrhoidectomy can be a safe and efficient alternative to conventional treatment for hemorrhoids that are causing symptoms.

Polidocanol Foam Sclerotherapy Versus Rubber Band Ligation in Hemorrhoidal Disease Grades I/II/III: Randomized Trial

BACKGROUND

Rubber band ligation and sclerotherapy are considered the office-based procedures of choice in hemorrhoidal disease. However, there are no studies comparing rubber band ligation and polidocanol foam sclerotherapy.

OBJECTIVE

We aimed to evaluate the efficacy and safety of polidocanol foam sclerotherapy compared with rubber band ligation.

DESIGN

This study was a randomized open-label study with 1-year follow-up.

SETTINGS

The study was conducted in the colorectal unit of a tertiary hospital.

PATIENTS

One hundred twenty patients with hemorrhoidal disease grades I to III were included.

INTERVENTIONS

Patients were stratified by hemorrhoidal disease grade and randomly assigned (1:1) to treatment with either rubber band ligation (n = 60) or polidocanol foam sclerotherapy (n = 60).

MAIN OUTCOME MEASURES

Efficacy outcomes included therapeutic success and recurrence. Safety outcomes included the occurrence of complications related to the procedures.

RESULTS

Therapeutic success was not significantly different between the groups (polidocanol foam sclerotherapy 93.3% vs rubber band ligation 85.0%, p = 0.14). However, complete success rate was higher in the polidocanol foam sclerotherapy group (88.3% vs 66.7%, p = 0.009) with fewer office-based sessions (mean ± SD: 1.32 ± 0.60 vs 1.62 ± 0.76, p = 0.02). Recurrence rates were lower in the polidocanol foam sclerotherapy group (16.1% vs 41.2%, p = 0.004). Most recurrences were mild (83.3%). Complications were more frequent in the rubber band ligation group (30.0% vs 10.0%, p = 0.01) and were mostly minor (91.7%). No severe complications were observed in either group.

LIMITATIONS

This study was performed in a single center, and both patients and investigators were not blinded to the treatment group.

CONCLUSIONS

Both procedures are effective in the treatment of hemorrhoidal disease grades I to III. Polidocanol foam sclerotherapy was more effective than rubber band ligation when considering complete success. Patients in the polidocanol foam sclerotherapy group needed fewer treatment sessions, had lower recurrence rates, and were less likely to have complications.

Sclerotherapy in Hemorrhoids

Injection sclerotherapy for all grades of interhemorrhoids in various situations and co-morbidities has become popular method of treatment. Several types of surgical operations both conventional and stapled hemorrhoidectomy has many and serious described side effects. On the contrary, proctoscopic injection sclerotherapy using some of the modern sclerosants and thin bore needle injections is an office-based ambulatory method of treatment of internal hemorrhoids; it is low in cost, devoid of any major complications besides it is quite successful as reported. Its safety and efficacy has been published in recent years. This manuscript is a result of thorough systemic review using PRISMA guidelines on various sclerosing agents, their merits and demerits, methods of administration, and outcome in internal hemorrhoids.

The use of topical anaesthetic in the banding of internal haemorrhoids: a feasibility study for a randomised control trial

INTRODUCTION

Rubber band ligation (RBL) is a procedure commonly performed in colorectal clinics for internal haemorrhoids. Overall, 90% of patients experience pain following RBL. We aimed to complete a feasibility randomised control trial assessing the role of topical anaesthetic before RBL of internal haemorrhoids.

METHODS

We performed a prospective, single-centre, single blinded, randomised (1:1) control feasibility trial. Patients presenting with symptomatic haemorrhoids suitable for banding were randomised to undergo the procedure with local anaesthetic or without (control). Pain scores and vasovagal symptoms were assessed at 0 minutes, 30 minutes, 4 hours and 72 hours after the procedure. Primary outcome measures were recruitment rate, participant retention rate and patient and surgeon acceptability. Secondary outcome measures were pain scores up to 72 hours, vasovagal episodes, new use of analgesia and adverse outcomes.

RESULTS

In total, 35 patients (18 topical anaesthetic, group A; 17 no anaesthetic gel, group B) were recruited. Mean recruitment rate was 11.7 participants per month. Thirty-three (94%) participants remained in the study until completion, with two patients lost to telephone follow-up. The treatment was acceptable for 35 (97%) eligible patients. One patient declined enrolment. The treatment was acceptable to all surgeons (100%). There was a significant difference in median pain scores of -2 (95% CI -4.0 to -1.0, p=0.0006) at the 30-minute time point only. There was no significant difference in vasovagal symptoms (p=0.10) or new analgesia use (p=0.85).

CONCLUSION

We have shown that a phase III clinical trial is feasible for assessing the role of topical anaesthetic before RBL of internal haemorrhoids. We have demonstrated excellent patient recruitment and retention as well as patient and surgeon acceptability.

Recommendations and best practice on the management of hemorrhoidal disease in Saudi Arabia

BACKGROUND

Several techniques were developed for managing hemorrhoidal disease, but their use in clinical practice and the general management of the condition, seems highly variable in Saudi Arabia.

CONSENSUS PANEL

To develop consensus recommendations that ensure the best possible diagnosis and treatment of hemorrhoidal disease in Saudi Arabia, the consensus panel consisted of experts in surgery in Saudi Arabia who met from December 2017 to September 2018.

CONSENSUS FINDINGS

The discussions focused on the need: to set up a proctology society in Saudi Arabia to assess the prevalence of hemorrhoidal disease and to regulate the role of healthcare professionals (HCPs) in the management of the disease; to initiate guidelines to ensure proper diagnosis (considering symptoms, medical history and physical/clinical examination) and treatment (topical creams and suppositories should be limited as no strong evidence supports their efficacy); to educate patients on diet and lifestyle modifications using education materials and social media during and after the treatment (regular physical activity, drinking enough fluids, regular meal time with food rich in fibers, and regular bowel habit with non-straining defecation); to refer patients to a general/colorectal surgeon when needed; and to teach junior surgeons the best use of surgical techniques.

CONCLUSION

These recommendations can be a step forward towards a recognized guidance for all HCPs in Saudi Arabia for a better management of hemorrhoidal disease. They will be of a great value for general practitioners, family medicine doctors, junior surgeons and pharmacists who are the gate keepers and first contact with patients.

Interventional treatments for prolapsing haemorrhoids: network meta-analysis

Background

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.

Methods

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.

Results

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.

Conclusion

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.

Open Hemorrhoidectomy With Ligasure™ Under Local or Spinal Anesthesia: A Comparative Study

BACKGROUND

There is increasing evidence that many anorectal surgical procedures may be performed under local anesthesia. The aim of the present study was to evaluate the safety and efficacy of local anesthesia in the outpatient clinic vs spinal anesthesia in the operating room for open hemorrhoidectomy.

METHODS

Sixty-two patients with grade III or IV hemorrhoids underwent open hemorrhoidectomy with LigaSure™ between 2018 and 2020. Of them, 32 procedures were performed in the operating room under spinal anesthesia with hyperbaric bupivacaine and other 30 procedures were undertaken in the outpatient clinic under local anesthesia with ropivacaine.

RESULTS

There were no significant differences regarding age, gender, American Society of Anesthesiologists class, and Goligher's grade in between groups. No significant differences were observed in postoperative pain score (P = .85), perioperative complications (P = .51), and reoperation rate (P = .96). No recurrences and no differences in patients' satisfaction degree (P = .76) were documented at long-term follow-up in both study groups.

DISCUSSION

Our results suggest that open hemorrhoidectomy with LigaSure™ performed in selected patients under local anesthesia in the outpatient clinic is a well-tolerated, safe, and effective procedure.

Intra-abdominal rectal perforation post-haemorrhoidal artery ligation operation and converted Ligasure open haemorrhoidectomy

We report an unfortunate case of rectal perforation and subsequent peritonitis in a 74-year-old lady who underwent haemorrhoidal artery ligation in order to treat complex large external and internal haemorrhoids. Serious complications following haemorrhoid surgery are rare and this is the first documented case of delayed intra-abdominal rectal perforation following a haemorrhoid artery ligation operation and converted Ligasure open haemorrhoidectomy.

Socio-demographic factors and lifestyle behaviors associated with symptomatic hemorrhoids: Big data analysis using the National Health insurance Service-National Health screening cohort (NHIS-HEALS) database in Korea

OBJECTIVE

The prevalence of hemorrhoids has been reported to be 7-14%. However, there have been no large-scale studies. This study aims to investigate the incidence of hemorrhoids in Korea by analyzing big data and to find the associated risk factors.

METHODS

This was a retrospective analysis using the Health Insurance Cohort database of the National Health Insurance Corporation of Korea in 2002-2015. The study was divided into two models: the diagnostic (DM) and surgical model (SM). Socio-demographic and lifestyle behavioral characteristics were analyzed as risk factors.

RESULTS

Overall, 467,567 participants were included. The incidence density of hemorrhoids was 13.9 and 5.7 per 1000 person-years in the DM and SM, respectively. Hemorrhoids occurred more frequently in men and metropolitan areas in both models. The incidence was highest in the 40s. The incidence rates were highest in the high income, smoking, alcohol and the exercise group of 1-4 times a week in both models. The adjusted hazard ratio (HR) was higher in men and decreased with increasing age. It was higher in the metropolitan area. The high-income level and alcohol consumption were risk factors in the DM and SM, respectively. The HR of the exercise group was higher than that of the non-exercise group in both models.

CONCLUSIONS

The diagnostic and surgical incidence density was 13.9 and 5.7 per 1000 person-years, respectively. Hemorrhoids occurred most frequently in men in their 40s. The metropolitan area, high income level and alcohol consumption were associated with an increased frequency of hemorrhoids.

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.

Belgian consensus guideline on the management of hemorrhoidal disease

Introduction

Hemorrhoidal disease is a common problem that arises when hemorrhoidal structures become engorged and/or prolapse through the anal canal. Both conservative and invasive treatment options are diverse and guidance to their implementation is lacking.

Methods

A Delphi consensus process was used to review current literature and draft relevant statements. These were reconciliated until sufficient agreement was reached. The grade of evidence was determined. These guidelines were based on the published literature up to June 2020.

Results

Hemorrhoids are normal structures within the anorectal region. When they become engorged or slide down the anal canal, symptoms can arise. Every treatment for symptomatic hemorrhoids should be tailored to patient profile and expectations. For low-grade hemorrhoids, conservative treatment should consist of fiber supplements and can include a short course of venotropics. Instrumental treatment can be added case by case : infrared coagulation or rubber band ligation when prolapse is more prominent. For prolapsing hemorrhoids, surgery can be indicated for refractory cases. Conventional hemorrhoidectomy is the most efficacious intervention for all grades of hemorrhoids and is the only choice for non-reducible prolapsing hemorrhoids.

Conclusions

The current guidelines for the management of hemorrhoidal disease include recommendations for the clinical evaluation of hemorrhoidal disorders, and their conservative, instrumental and surgical management.

Effectiveness and cost-effectiveness of rubber band ligation versus sutured mucopexy versus haemorrhoidectomy in patients with recurrent haemorrhoidal disease (Napoleon trial): Study protocol for a multicentre randomized controlled trial

BACKGROUND

Currently, there is no consensus regarding the best treatment option in recurrent haemorrhoidal disease (HD), due to a lack of solid evidence. The Napoleon trial aims to provide high-level evidence on the comparative effectiveness and cost-effectiveness of repeat rubber band ligation (RBL) versus sutured mucopexy versus haemorrhoidectomy in patients with recurrent HD.

METHODS

This is a multicentre randomized controlled trial. Patients with recurrent HD grade II and III, ≥18 years of age and who had at least two RBL treatments in the last three years are eligible for inclusion. Exclusion criteria include previous rectal or anal surgery, rectal radiation, pre-existing sphincter injury or otherwise pathologies of the colon and rectum, pregnancy, presence of hypercoagulability disorders, and medically unfit for surgery (ASA > III). Between June 2020 and May 2022, 558 patients will be randomized to receive either: (1) RBL, (2) sutured mucopexy, or (3) haemorrhoidectomy. The primary outcomes are recurrence after 52 weeks and patient-reported symptoms measured by the PROM-HISS. Secondary outcomes are impact on daily life, treatment satisfaction, early and late complication rates, health-related quality of life, costs and cost-effectiveness, and budget impact. Cost-effectiveness will be expressed in societal costs per Quality Adjusted Life Year (QALY) (based on EQ-5D-5L), and healthcare costs per recurrence avoided.

DISCUSSION

The best treatment option for recurrent HD remains unknown. The comparison of three generally accepted treatment strategies in a randomized controlled trial will provide high-level evidence on the most (cost-) effective treatment.

Evaluating the ability of the Sodergren score to guide the management of internal haemorrhoidal disease

AIM

The Sodergren score was developed to objectively measure the severity of haemorrhoidal symptoms. This study aimed to determine if there was a difference in the Sodergren score between patients who were offered surgery and patients who underwent successful rubber band ligation of internal haemorrhoidal disease and to assess its performance in guiding management.

METHOD

This is a prospective, observational study. The preintervention Sodergren scores of subjects with internal haemorrhoidal disease were recorded and blinded to the surgeon in charge. Sodergren scores of subjects in the two arms were unblinded and compared at the end of the study.

RESULTS

The results for 290 patients were available for final analysis. The median scores of those offered surgery and those who underwent successful rubber band ligation differed significantly [4 (interquartile range 3-10) vs 0 (interquartile range 0-4), P = 0.001]. In predicting treatment, the Sodergren score had an area under the receiver operating characteristic curve of 0.735 (95% CI 0.675-0.795).

CONCLUSION

There is a significant difference in scores between patients who were offered surgery and patients with successful rubber band ligation. Our study suggests that the Sodergren score has an acceptable discrimination in predicting the need for surgery in internal haemorrhoidal disease. We propose that patients with a Sodergren score of 6 or more be considered for upfront surgery. This score could potentially be used to standardize outcomes of future haemorrhoid trials.

Still a Case of "No Pain, No Gain"? An Updated and Critical Review of the Pathogenesis, Diagnosis, and Management Options for Hemorrhoids in 2020

The treatment of haemorrhoids remains challenging: multiple treatment options supported by heterogeneous evidence are available, but patients rightly demand a tailored approach. Evidence for newer surgical techniques that promise to be less painful has been conflicting. We review the current evidence for management options in patients who present with varying haemorrhoidal grades. A review of the English literature was performed utilizing MEDLINE/PubMed, Embase, and Cochrane databases (31 May 2019). The search terms (haemorrhoid OR haemorrhoid OR haemorrhoids OR haemorrhoids OR “Hemorrhoid”[Mesh]) were used. First- and second-degree haemorrhoids continue to be managed conservatively. The easily repeatable and cost-efficient rubber band ligation is the preferred method to address minor haemorrhoids; long-term outcomes following injection sclerotherapy remain poor. Conventional haemorrhoidectomies (Ferguson/Milligan-Morgan/Ligasure haemorrhoidectomy) still have their role in third- and fourth-degree haemorrhoids, being associated with lowest recurrence; nevertheless, posthaemorrhoidectomy pain is problematic. Stapled haemorrhoidopexy allows quicker recovery, albeit at the costs of higher recurrence rates and potentially serious complications. Transanal Haemorrhoidal Dearterialization has been promoted as nonexcisional and less invasive, but the recent HubBLe trial has questioned its overall place in haemorrhoid management. Novel “walk-in-walk-out” techniques such as radiofrequency ablations or laser treatments will need further evaluation to define their role in modern-day haemorrhoid management. There are numerous treatment options for haemorrhoids, each with their own evidence-base. Newer techniques promise to be less painful, but recurrence rates remain an issue. The balance continues to be sought between long-term efficacy, minimisation of postoperative pain, and preservation of anorectal function.

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.

Hemorrhoid management in women: the role of tribenoside + lidocaine

Hemorrhoids are commonly reported in women. However, despite the high prevalence of hemorrhoids in women and the major impact of this condition on quality of life, specific evidence and recommendations on the treatment of hemorrhoids in women are scant. This paper reviews various options in current therapy for hemorrhoids in women—namely, medical intervention (topical and systemic drug therapy)—and discusses the available clinical evidence for an appropriate use of over-the-counter topical formulations for the symptomatic treatment of hemorrhoids. Its focus is on a medical preparation containing tribenoside + lidocaine, available as a rectal cream (tribenoside 5%/lidocaine 2%) and a suppository (tribenoside 400 mg/lidocaine 40 mg) and marketed under the brand Procto-Glyvenol^® (Recordati, SpA, Italy). Given its rapid comprehensive efficacy on all the different symptoms of hemorrhoids, the tribenoside + lidocaine combination can find a place in the treatment of this hemorrhoidal disease. Importantly, its efficacy and tolerability have been formally evaluated in several well-conducted studies, some of which were specifically conducted in women. In particular, tribenoside + lidocaine can be safely administered in postpartum women and in pregnant women after the first trimester of pregnancy. In pregnant women, the tribenoside/lidocaine combination significantly improved both subjective and objective symptoms of hemorrhoids. Fast onset of symptom relief was reported from 10 minutes after administration, lasting up to 10–12 hours. On these bases, tribenoside + lidocaine can represent a fast, effective, and safe option to treat hemorrhoids when conservative therapy is indicated, and it deserves consideration as a first-line treatment of this disease in clinical practice.

Effectiveness of Endoscopic Sclerotherapy with Aluminum Potassium Sulfate and Tannic Acid as a Non-Surgical Treatment for Internal Hemorrhoids

BACKGROUND/AIMS

Sclerotherapy with aluminum potassium sulfate and tannic acid (ALTA) has a potent effect on internal hemorrhoids. In this retrospective study, we compared the effects of endoscopic ALTA therapy and standard ALTA therapy.

METHODS

We investigated patients who underwent treatment for internal hemorrhoids at our institution between 2014 and 2016. They were divided into a standard ALTA group (n=33, treated using proctoscopy) and an endoscopic ALTA group (n=48). We compared the clinical findings between the 2 groups.

RESULTS

There were no intergroup differences in background factors. The mean ALTA dose was 21.9±7.2 mL and 17.8±3.4 mL in the standard and endoscopic ALTA groups, respectively (p<0.01). Adverse events occurred in 4 patients (12.1%) from the standard ALTA group and 6 patients (12.5%) from the endoscopic ALTA group. In both groups, the patients reported good satisfaction with the therapeutic effect at 1 month after the procedure. Hemorrhoids recurred in 2 patients (6.3%) from the standard ALTA group and 4 patients (8.3%) from the endoscopic ALTA group.

CONCLUSION

Endoscopic ALTA sclerotherapy is equivalent to standard ALTA therapy in terms of efficacy, adverse events, and recurrence. Therefore, it is a useful non-surgical option for patients with internal hemorrhoids who prefer a less invasive treatment.

Inferior load generated by preloaded versus manually loaded haemorrhoid banding devices: the effect of 'creep relaxation'

BACKGROUND

The efficacy of rubber band ligation of haemorrhoids relies on the load generated on haemorrhoidal tissue by bands as they return to their preformed shape after being deployed. 'Preloaded' haemorrhoid banding devices are widely available, but the effect of the resultant prolonged stretch on bands while stored in this manner has never been examined by comparing these to manually loaded devices, which are stretch immediately prior to being deployed. A difference could have clinical relevance, potentially resulting in a higher rate of clinical failure. The present study aimed to investigate any difference in load generated by preloaded versus manually loaded devices.

METHODS

A preloaded and a manually loaded device were selected for comparison. Each type was measured on a testing rig. The device type, load generated by each band and the time to expiry were recorded.

RESULTS

A total of 137 haemorrhoid bands were tested: 66 preloaded and 71 manually loaded. There was a statistically significant overall reduction in load generated by preloaded versus manually loaded devices (284.0 versus 272.1 g, mean difference -11.9 g, 95% confidence interval -17.5 to -6.3 g, P = 0.0001). Adjusted for time, the load generated by preloaded bands fell 3.7 g (95% confidence interval 2.7-4.8, P < 0.001) for each month closer to the expiry date.

CONCLUSIONS

The load generated by haemorrhoid bands from preloaded devices is lower and deteriorates significantly towards their expiry date compared with bands from manually loaded devices. This is mostly likely due to their storage in a stretched state. This should be considered by clinicians when using haemorrhoid banding devices.

Evaluation of Natural Extracts in Animal Models of Pain and Inflammation for a Potential Therapy of Hemorrhoidal Disease

The aim of this work was to assess the analgesic effect of three Vitis vinifera L. leaf extracts and the anti-inflammatory effect of three gels obtained from Aesculus hippocastanum L. seed extracts using animal models, as a preliminary study for the future development of topical preparations based on the combination of extracts with synergistic therapeutic effects on hemorrhoid disease. The analgesic effect was determined by means of the writhing test in mice. The anti-inflammatory effect was determined after administration of carrageenan or kaolin in the rat paw. Extraction using glycerol yielded the highest amounts of flavonoids for both V. vinifera leaves (37.27 ± 1.174 mg/L) and A. hippocastanum seeds (53.48 ± 0.212 mg/L). The highest total phenolic contents were registered for the V. vinifera 20% ethanolic extract (615.3 ± 34.44 mg/L) and for the A. hippocastanum glycerolic extract (247.8 ± 6.991 mg/L). The writhing test revealed that the V. vinifera ethanolic extract induced the most efficient analgesia (57.20%, p < 0.01), better than that induced by the positive control. In the carrageenan inflammation model, only the gel obtained from the A. hippocastanum glycerolic extract significantly reduced paw edema (17.27%, p < 0.05). An anti-inflammatory effect was also observed in the kaolin inflammation model but was not statistically significant (10.12%, p > 0.05). Our findings indicate that V. vinifera and A. hippocastanum extracts may have potential uses for the treatment of pain and inflammation associated with hemorrhoid disease.

External hemorrhoidal disease in child and teenage: Clinical presentations and risk factors

Objective

Hemorrhoidal disease (HD), though mostly seen in adults, has recently emerged as a common problem among children. However, the diagnosis and treatment of HD in children is mostly based on the data obtained in adult studies. In this study, we aimed to evaluate risk factors, diagnostic and treatment modalities in the children diagnosed with external HD.

Methods

The study was conducted at Sakarya University Medical School Pediatric Surgery Department between January 2012 and July 2018. We reviewed children who were diagnosed as having HD at Pediatric Surgery clinic. Age, gender, presenting symptoms, physical examination findings, risk factors, and treatment outcomes were evaluated for each patient.

Results

The study included 56 patients with a mean age of 140.8±45.2 months. The patients comprised 48 (85.7%) boys and 8 (14.3%) girls. Constipation and a positive family history were the most common risk factor (n=33; 58.9%, n=29; 51.8%, respectively). Conservative treatment was performed in 53 (94.6%) patients. Recurrence was observed in 5 (8.9%) and skin tag was detected in 6 (10.7%) patients.

Conclusions

External HD mostly occurs in boys in their second decade of life. Positive family history and constipation were the most common risk factors in our patients. Conservative treatment is sufficient for the management of external HD in children because of its low recurrence rates.

Pathophysiology of internal hemorrhoids

Hemorrhoidal disease is a fairly common and debilitating clinical entity. Despite centuries’ of attempts to shed light on its pathophysiology, to cure those affected and to improve sufferers’ quality of life, many aspects of the disease remain elusive. Individual beliefs and historical legends, accompanied by undocumented theories, have established and perpetuated the confusion regarding the mechanisms leading to the development of the disease and the rules governing its treatment. Hemorrhoids are classified as internal or external and are viewed as a disease when they become symptomatic. Returning to basic medical sciences, this mini-review focuses on internal hemorrhoids and aims to define the histology and anatomy of the normal and abnormal internal hemorrhoidal plexus and to encourage clinicians to comprehend the pathophysiology of the disease. If doctors can understand the pathophysiology of hemorrhoidal disease, they will be able to clarify the nature of the associated symptoms and complications and to make the correct therapeutic decision.
