Treatment of hemorrhoids: A coloproctologist’s view

Prospective Comparative Analysis of the Incidence of Vasovagal Reaction and the Effect of Rectal Submucosal Lidocaine Injection in Stapled Hemorrhoidopexy: A Randomized Controlled Trial

Purpose

This study was performed to evaluate the incidence of vasovagal reactions (VVRs) and the efficacy of lidocaine injection for prevention.

Methods

One hundred seventeen patients diagnosed with hemorrhoids and scheduled to undergo a stapled hemorrhoidopexy (SH) were randomly divided according to submucosal injection to the rectum: lidocaine group (n = 53, lidocaine injected just before full closure of the stapler) and control group (n = 58). Outcomes included baseline patient characteristics (American Society of Anesthesiologists physical status classification, body mass index, diabetes mellitus, hypertension, and previous VVR history), vital signs during the operation, incidence of VVRs (hypotension, bradycardia, dizziness, diaphoresis, and nausea/vomiting), and postoperative complications (pain, bleeding, and urinary retention).

Results

Baseline characteristics were similar between groups. The number of patients with lower abdominal pain after firing the stapler and incidence of dizziness were lower for the lidocaine group than for the control group (9.4% vs. 25.9%, P = 0.017; 0% vs. 8.6%, P = 0.035, respectively). However, there were no significant between-group differences in incidence of nausea and diaphoresis (0% vs. 3.4%, P = 0.172) and syncope (1.9% vs. 3.4%, P = 0.612). Fewer patients in the lidocaine group complained of postoperative pain (41.5% vs. 58.6%, P = 0.072), and these patients used analgesics less frequently than those in the control group (28.3% vs. 36.2%, P = 0.374).

Conclusion

Patients who received a submucosal lidocaine injection prior to SH experienced less lower abdominal pain and dizziness compared with those who received standard treatment. A larger, more detailed prospective study is needed for further analysis.

Effect of Topical Baclofen 5% on Post-Hemorrhoidectomy Pain: Randomized Double Blind Placebo-Controlled Clinical Trial

BACKGROUND

Baclofen is an agonist for a subtype of gamma-amino butyric acid (GABA-B) receptors and traditionally been used for the systemic treatment of spasticity. Topical application of baclofen has been shown to reduce pain in patients with localized neuropathic pain.

OBJECTIVES

In this study, we investigate the efficacy of baclofen cream (5%) in reducing postoperative pain and analgesic requirement after open hemorrhoidectomy.

DESIGN

The patients were randomly assigned to either baclofen (5%) cream or placebo immediately after surgery and then every 12 h for 14 days.

PATIENTS

A total of 66 patients with third- and fourth-degree hemorrhoids undergoing open hemorrhoidectomy were randomly assigned to this trial.

SETTING

This study was conducted at a single educational hospital.

PRIMARY AND SECONDARY OUTCOME MEASURES

The primary outcomes were intensity of pain, measured with a visual analog scale, and the analgesic requirement, measured by the amount of the acetaminophen consumption.

RESULTS

No significant difference was found in baseline characteristics between the two groups. Postoperative pain score of the baclofen group was significantly lower on week 1 (P = 0.01) and week 2 (P = 0.02) than the placebo group. Similarly, patients in the baclofen group consumed significantly less analgesic medication on week 1 (P = 0.025) and week 2 (P = 0.024) than the control group.

CONCLUSION

Topical application of baclofen effectively relieves pain after hemorrhoidectomy with minimal side effects.

Role of a Micronized Purified Flavonoid Fraction as an Adjuvant Treatment to Rubber Band Ligation for the Treatment of Patients With Hemorrhoidal Disease: A Longitudinal Cohort Study

Purpose

Nonsurgical treatment of hemorrhoidal disease (HD) includes medical and instrumental techniques. We aimed to compare the efficacy of the most frequently used nonsurgical strategies, either alone or in combination, applied in an ambulatory setting.

Methods

Patients who received nonsurgical treatment for HD by proctology appointment at the Gastroenterology Department of Braga Hospital were evaluated. Isolated rubber band ligation (RBL) and a combination of RBL with a micronized purified flavonoid fraction (MPFF) were the 2 most frequently used strategies. Symptoms of HD (bleeding, pruritus, pain at rest, pain at defecation and prolapse) were assessed at days 0, 7, and 28 by using a severity grading scale (0 to 4/5). A Global Symptom score was constructed to assess the overall severity and compare the overall improvements of the HD symptoms between the 2 most frequently used strategies.

Results

Nineteen patients underwent the combined treatment (RBL + MPFF group) and 25 the RBL treatment (RBL group). A comparison of the 2 treatment groups showed significant improvements in the combined treatment group in terms of bleeding at days 7 (P = 0.001) and 28 (P = 0.002) and in the pruritus intensity during the first week (P < 0.001). A trend toward clinical benefit was also verified in the combined treatment group for all other HD symptoms (pain at rest, pain at defecation and prolapse).

Conclusion

A combined treatment approach with MPFF and RBL significantly reduced the intensity of bleeding during the first month and the pruritus during the first week.

A Case Control Study on Physical Activity and Body Mass Index Associated with Hemorrhoids

Introduction: Body mass index (BMI) and physical activity are the controversial risk factors that cause hemorrhoids. This study was conducted to determine the association between body mass index and physical activity.Methods: This was a case-control study which involved two hundred and two patients using convenience sampling. They had to answer a questionnaire consisting of the International Physical Activity Questionnaire (IPAQ) which monitored their physical activity and their BMI was also measured. For the descriptive analysis, Chi square and an odd ratio were carried out.Results: There was a significant association between age and hemorrhoids (p=0.02), in which the patients who were younger than 50 years old were more likely to have hemorrhoids compared to those who were older than 50 years old (OR=2.268, 95%CI: 1.107-4.630). For the risk estimation calculation, the Chinese individuals were found to have a higher risk compared to non-Chinese individuals (OR=2.056, 95% CI: 1.174-3.601). BMI was proven to be significantly associated with hemorrhoids (p=0.043). Physical activities were found to not be statistically significant (p=0.209). Those with a low and moderate physical activity level were 1.24 times more likely to have hemorrhoids compared to those with a high level of physical activity (OR=1.243, 95%CI:   0.697-2.217). The confidence interval was between 0.697 and 2.217, therefore it was not statistically significant.Conclusion: Physical activity was not associated with the hemorrhoids. However, it was shown that good physical activity could help to regulate bowel function and therefore, the occurrence of hemorrhoids would be less likely. BMI was significantly associated with hemorrhoids.

Association of Hemorrhoids With Hashimoto's Thyroiditis and Associated Comorbidities: A Nationwide Population-Based Cohort Study

Background: To evaluate the relationship between hemorrhoids and Hashimoto's thyroiditis (HT). Methods: Using Taiwan's Longitudinal Health Insurance Database, we compared the incident risk of HT between the study cohort (comprising patients with hemorrhoids) and the comparison cohort (comprising patients without hemorrhoids). Both cohorts were followed from index date until the date of HT diagnosis, withdrawal from the National Health Insurance program, or the end of 2015. Results: The study cohort and comparison cohort comprised 6,486 patients with hemorrhoids and 25,944 patients without, respectively. The mean follow-up time was ~3 years. The incidence rate of HT in the study cohort was 5.37 per 1,000 person-years, which was higher than that of the control cohort (2.46 per 1,000 person-years). The risk of developing HT in the study cohort was 2.06 times (95% confidence interval [CI] = 1.02, 4.19) higher than that in the comparison cohort. Conclusion: In our study, patients with hemorrhoids could be at increased risk of HT compared with patients with other comorbidities of HT, such as cardiovascular disease.

Post hemorrhoidectomy complications: CT imaging findings

INTRODUCTION

We aimed to describe computed tomography (CT) findings of early complications after interventional hemorrhoid treatments in emergency department (ED) patients.

MATERIALS AND METHODS

We identified all ED patients requiring abdominal and/or pelvic CT between February 2012 and February 2019, and included only patients who underwent CT for suspected early (up to 30 days) post hemorrhoidectomy procedure complications. Presenting symptoms, salient CT findings and clinical outcomes were collected.

RESULTS

Overall, 48,425 abdominal and/or pelvic CTs were performed. Of these, we identified 12 patients (8 male, 4 female) who underwent CT in our ED following hemorrhoidectomy procedures. At presentation, peri-anal or abdominal pain was the most common symptom. One patient presented with hemodynamic instability. CT findings included proctitis (4/12), rectal perforation (2/12), peri-anal abscess (1/12) and peri-anal fistula (1/12). Two of the patients with proctitis presented with significant submucosal edema. On follow-up, three patients required intensive care hospitalization, and two of those underwent emergent laparotomy. The third patient died due to secondary infection during his hospitalization.

CONCLUSION

Hemorrhoidectomy procedures may result in severe complications which should be recognized by ED radiologists. These complications carry a potential risk for significant clinical consequences. Both clinicians and radiologists should be aware of the possibility of such complications when patients present to the ED early after hemorrhoid procedures.

Comparative Study of 0.2% Glyceryl Trinitrate Ointment for Pain Reduction after Hemorrhoidectomy Surgery

Context  Hemorrhoid is one of the most common diseases in both, men and women, affecting half of the world's population over the age of 50.

Aims  The aim of this study was to evaluate the analgesic effects of local ointment of glyceryl trinitrate ointment (GTN) after hemorrhoidectomy.

Methods and Materials  In this randomized double-blind, placebo-controlled study, the patients were grouped as the treatment, that is GTN, and placebo (P) group. After surgery, 0.2% gelatin GTN ointment (250 mg), and P ointment ( n  = 20 for each group) were applied topically on 1 cm on the anus using a standard ruler, three times a week in respective groups. visual analog scale was used to assess the intensity of the pain and complications of the drugs were observed at 6, 12, 18, and 24 hours.

Statistical Analysis Used  Data and questionnaires were analyzed statistically using SPSS17 software and results were recorded in the tabular form.

Results  Six hours after the application of the ointment, no significant difference was found among the groups, however, after 12, 18, and 24 hours significant reduction in pain was seen in GTN group, which was least after 18 hours. The mean values of the total pain score in the first 24 hours after surgery in the GTN group were 3.15 and 5.45 in the P group which were statistically significant. Nonetheless, headache was significantly increased in the GTN group.

Conclusion  Simple and safe topical GTN ointment can reduce the pain after hemorrhoidectomy, leading to the reduced need of other analgesics.

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.

miR-412-5p targets Xpo1 to regulate angiogenesis in hemorrhoid tissue

Hemorrhoid is a common and recurrent proctological disease, which is often accompanied by angiogenesis and edema. MicroRNAs in the DLK1-DIO3 imprinted clusters are involved in the development and pathogenesis of mammalian hemorrhoids. Results of the present study indicated multiple, differential expression of DLK1-DIO3 imprinted cluster microRNA between hemorrhoid and normal tissues, where miR-412-5p expression in hemorrhoid tissue was significantly decreased. Fluorescein reporter assays showed that miR-412-5p silenced Xpo1 mRNA expression by targeting its 3'-UTR. Overexpression of miR-412-5p in human umbilical vein endothelial cells (HUVECs) indicated that proliferation, migration and formation of vascular structures in HUVECs were inhibited in vitro. In addition, overexpression of miR-412-5p significantly inhibited Xpo1 expression and promoted upregulation of the p53 protein and its retention in the nucleus. Simultaneously, expression of p66SHC and p16 proteins was activated. In summary, downregulation of endogenous miR-412-5p expression in hemorrhoid vascular endothelial cells leads to high expression of the target gene Xpo1 and translocation of the p53 protein out of the nucleus, rendering it unable to activate p66SHC and p16. This ultimately weakens regulation of the vascular endothelial cell cycle, thereby accelerating the division of hemorrhoid vascular endothelial cells, leading to angiogenesis.

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.

Comparison of Doppler-Guided Transanal Hemorrhoidal Dearterialization for Grade III and IV Hemorrhoids in Vietnam

INTRODUCTION

This study aimed to assess the short- and long-term outcomes of Doppler-guided transanal hemorrhoidal dearterialization (THD) for grade III and IV hemorrhoidal disease in Vietnam.

METHODS

In a prospective observational design, patients treated for grade III and IV hemorrhoidal disease with the THD method at the National Hospital of Traditional Medicine (Hanoi, Vietnam) were included between June 2012 and December 2013. Patients were evaluated postoperatively at the time they were discharged from the hospital (short-term outcome) and 6 months after surgery (long-term outcome).

RESULTS

A total of 128 patients were enrolled in the study, 94 were classified with grade III disease and 34 with grade IV. Grade IV hemorrhoidal patients reported on average 18.2 years of disease symptom duration, while grade III hemorrhoidal patients reported 11.2 years. All patients with grade III and grade IV hemorrhoidal disease had good outcomes at discharge day and reported to return to work in a median of 6 days after THD. At long-term follow-up, the results were good for 80.9% of patients from grade III hemorrhoidal disease and 61.8% of patients from grade IV hemorrhoidal disease. Patient satisfaction with the procedure and outcomes was 93.6% for grade III and 85.3% for grade IV hemorrhoidal patients.

CONCLUSIONS

The THD technique was shown to be safe for both grade III and IV hemorrhoidal patients. The THD technique showed better results with grade III hemorrhoidal patients as compared to grade IV hemorrhoidal patients.

Classification and guidelines of hemorrhoidal disease: Present and future

Classification and guidelines of hemorrhoidal disease are based on the subdivision in Grades of prolapse followed by any aspect related to both the treatment and its technique. When taking the proposals for classification and guidelines issued by prolific scientific societies into consideration, it is evident that strong contradictions and interpretative limits emerge in finding the best treatment to be adopted. After a critical examination of these limitations, a methodological proposal is shared to achieve a new classification, which plays a part in forming a new guideline for hemorrhoidal disease, identifying its evolution, dynamism of the prolapse, symptomatology, enteropathogenesis and gender characteristics.

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.

Flavonoid mixture (diosmin, troxerutin, rutin, hesperidin, quercetin) in the treatment of I-III degree hemorroidal disease: a double-blind multicenter prospective comparative study

PURPOSE

We evaluated the efficacy of new flavonoids mixture (diosmin, troxerutin, rutin, hesperidin, quercetin) to reduce bleeding from I-III degrees hemorrhoidal disease in the short and medium time.

METHODS

One hundred fifty-four consecutive patients with hemorrhoidal disease recruited in four colorectal units were enrolled to the study. Exclusion criteria were allergy to the flavonoids, inflammatory bowel disease, obstructed defecation syndrome, pregnancy and puerperium, associated anal disease or hemorrhoidal thrombosis, proctologic surgical procedures within 1 year before recruitment, contemporary cancer or HIV, previous pelvic radiotherapy, patients receiving oral anticoagulant therapy, or contemporary administration of other therapy for hemorrhoids. Patients with inability to understand the study or mental disorders were also excluded.

RESULTS

Seventy-eight were randomized to receive the mixture of diosmin, troxerutin, rutin, hesperidin, and quercetin (study group, SG), and 76 a mixture of diosmin in combination with hesperidin, diosmetin, isoroifolin, and linarin in purified micronized fraction (control group, CG). Bleeding, number of pathological piles, and Golligher's grade were assessed at each scheduled visit and compared using the Chi-square test. During the study period, bleeding improved after 1 and 6 months both in the SG (79.5 and 70.5%) and in the CG (80.2 and 75%) without significant differences between two groups. Satisfaction degree after 6 months was greater in the patients of the SG (4.05) towards the CG (3.25): this result was statistical significant (p 0.003).

CONCLUSIONS

Use of flavonoids mixture (diosmin, troxerutin, rutin, hesperidin, quercetin) is a safe and effective mean of managing bleeding from hemorrhoidal disease and minimal adverse events are reported.

Conservative Treatment of Hemorrhoids: Results of an Observational Multicenter Study

INTRODUCTION

This study was conducted to determine the frequency of complaints in a cohort of patients with symptomatic hemorrhoidal disease (HD) treated with micronized purified flavonoid fraction (MPFF, Detralex). MPFF was selected for conservative treatment in this population owing to its proven effects on hemorrhoidal symptoms in a large number of patients.

METHODS

This multicenter, non-interventional study was part of the international CHORUS survey (Chronic venous and HemORrhoidal diseases evalUation for improvement of Scientific knowledge), conducted in nine centers in different regions of Russia with the participation of 80 coloproctologists. The study enrolled consecutive patients with complaints of hemorrhoids. All were prescribed MPFF-based conservative treatment. The effect of treatment on HD clinical signs and symptoms was assessed at two follow-up visits performed 5-7 days and 25-30 days after enrollment. Surgical and minimally invasive treatment could be performed from day 7 onwards if required.

RESULTS

A total of 1952 patients were enrolled. Over the entire period of observation, MPFF-based conservative treatment was effective in 1489 (76.3%) patients in eliminating the main clinical manifestations of disease, i.e., bleeding and prolapse of internal nodes. Invasive treatment was performed in 68 (3.5%) patients with grade IV hemorrhoids and was combined with MPFF conservative treatment in 395 (20.2%) patients with grades I-III hemorrhoids.

CONCLUSION

Conservative therapy with MPFF was beneficial for relieving hemorrhoidal symptoms in the majority of patients. MPFF-based treatment was most effective in patients with grade I and II hemorrhoids before irreversible degenerative changes in ligaments of the hemorrhoidal plexuses have occurred. It was also beneficial in preventing disease relapse in patients with more advanced HD and for promoting optimal conditions in the postoperative period.

Factors influencing patient delay in individuals with haemorrhoids: A study based on theory of planned behavior and common sense model

AIMS

This study aimed to describe the status of patient delay and examine related factors affecting patient delay in individuals with haemorrhoids in mainland China, based on theory of planned behaviour and common sense model.

BACKGROUND

Studies on patient delay have mainly focused on cancer, tuberculosis and myocardial infarction, but studies on patient delay in individuals with haemorrhoids have yet to be conducted. Compared with other diseases, haemorrhoids are initially considered benign. However, if patients with haemorrhoids seek delayed medical assistance, they pay a large cost for worse symptoms because they fail to seek timely treatments compared with those who receive appropriate treatments at early stages.

DESIGN

A cross-sectional study design was used.

METHODS

The current study was performed on 306 patients with haemorrhoids from June - October 2017. Data were collected via a self-administered pencil-and-paper survey that consisted of a multi-item questionnaire. Stepwise logistic regression analysis was conducted to explore the factors of patient delay.

RESULTS

Middle-aged participants were more than twice more likely to report patient delay than participants in other age groups. A high level of perceived self-efficacy, a high level of illness perceptions and perceived social impact were associated with prolonged delay.

CONCLUSION

This study showed that patient delay is common among patients with haemorrhoids in China. The influencing factors of patient delay were middle-aged, illness perceptions, perceived self-efficacy, and perceived social impact.

Polidocanol Foam Injected at High Doses with Intravenous Needle: The (Almost) Perfect Treatment of Symptomatic Internal Hemorrhoids

Background and Aims

Hemorrhoid disorders are common. This study aimed to assess the efficacy and safety of polidocanol foam injected at high doses with intravenous needle for the treatment of symptomatic internal hemorrhoids that prolapse or bleed.

Methods

We evaluated 2,000 consecutive patients with prolapsed hemorrhoids (grades II/III/IV) recruited over 6 years. Foam injection was performed in one to four sessions with polidocanol 2%: 10 mL of the mixture (2 mL liquid plus air) or 20 mL (4 mL liquid plus air). The number of sessions and amount of foam injected depended on initial hemorrhoid size, compliance to receive foam, and clinical response. The mixture, prepared using a three-way tap connected to two 10/20-mL syringes, was injected immediately after preparation using an intravenous needle. The primary endpoint was self-reported satisfaction without major complications at 4 weeks.

Results

Efficacy was very high, with 1,957 patients (98%) reporting satisfaction regarding blood loss control and prolapse reduction. The procedure was well tolerated: 1,838 patients (92%) presented mild/no pain. Objective reduction of prolapse volume was documented in 86% of reobserved cases. Complications were rare and usually minor: only 3 cases of clinically significant bleeding (0.15%), 2 of whom were on dual antiplatelet therapy plus oral anticoagulation, 2 cases of rectal abscess, 8 hemorrhoid thromboses, and 1 urinary retention requiring catheter (0.7% severe complications).

Conclusions

Treatment of internal hemorrhoids with polidocanol foam injected in high doses is very effective and safe for the control of blood loss and prolapse, even for patients on anticoagulation/antiplatelet treatment.

Endometriosis in the rectum accompanied by hemorrhoids leading to diagnostic pitfalls: a rare case report

Background

Hemorrhoid is a common anorectal disease. Hemorrhoids accompanied by endometriosis are unusual. As endometriosis in the rectum may mimic many other diseases, including cancer and inflammation, its diagnosis may be difficult, especially when it is combined with other diseases.

Case presentation

Here, we present a rare case of a patient with hemorrhoids accompanied by endometriosis in the rectum. The endometriosis mass was detected by digital rectal examination and CT scan and confirmed by pathological examination. The mass was approximately 0.8 cm × 0.6 cm and located in the muscularis and submucosa of the rectum 8 cm from the anus.

Conclusions

In this case, hemorrhoid is a common disease of rectum and anal canal. However, when it is complicated by another rare disease, the rare one can be easily neglected because of the existence of the common one, especially when the two diseases have similar lesions or symptoms. We suggest that strict physical examination, such as the digital rectal examination in the current case, is critical for correct disease diagnosis.

Traditional and modern aspects of hemorrhoid treatment in Iran: a review

Hemorrhoidal disease is a prevalent anorectal condition which is generally not managed well with current pharmacologic interventions. However, in Iranian traditional medicine (ITM) there are numerous plants with hemorrhoid-healing properties. The present research assembled plants with hemorrhoid-healing properties in ITM; their related pharmacological effects, phytochemical constituents and mechanisms of action in the modern medicine were also gathered. For this purpose, leading ITM textbooks were searched for plants with hemorrhoid-healing effects. Further, in vitro, in vivo and clinical studies on the most cited species were considered using scientific databases. Studying ITM textbooks revealed 37 medicinal plants with hemorrhoid-healing effects. Among the mentioned herbal medicines, six species, including Allium ampeloprasum, Phyllanthus emblica, Aloe vera, Terminalia chebula, Vitis vinifera and Commiphora mukul, had the largest number of related pharmacological effects documented in scientific databases. These herbs from ITM should be considered as important resources for producing novel drugs for hemorrhoid treatment.

The HubBLe Trial: haemorrhoidal artery ligation (HAL) versus rubber band ligation (RBL) for symptomatic second- and third-degree haemorrhoids: a multicentre randomised controlled trial and health-economic evaluation

BACKGROUND

Optimal surgical intervention for low-grade haemorrhoids is unknown. Rubber band ligation (RBL) is probably the most common intervention. Haemorrhoidal artery ligation (HAL) is a novel alternative that may be more efficacious.

OBJECTIVE

The comparison of HAL with RBL for the treatment of grade II/III haemorrhoids.

DESIGN

A multicentre, parallel-group randomised controlled trial.

PERSPECTIVE

UK NHS and Personal Social Services.

SETTING

17 NHS Trusts.

PARTICIPANTS

Patients aged ≥ 18 years presenting with grade II/III (second- and third-degree) haemorrhoids, including those who have undergone previous RBL.

INTERVENTIONS

HAL with Doppler probe compared with RBL.

OUTCOMES

Primary outcome - recurrence at 1 year post procedure; secondary outcomes - recurrence at 6 weeks; haemorrhoid severity score; European Quality of Life-5 Dimensions, 5-level version (EQ-5D-5L); Vaizey incontinence score; pain assessment; complications; and cost-effectiveness.

RESULTS

A total of 370 participants entered the trial. At 1 year post procedure, 30% of the HAL group had evidence of recurrence compared with 49% after RBL [adjusted odds ratio (OR) = 2.23, 95% confidence interval (CI) 1.42 to 3.51; p = 0.0005]. The main reason for the difference was the number of extra procedures required to achieve improvement/cure. If a single HAL is compared with multiple RBLs then only 37.5% recurred in the RBL arm (adjusted OR 1.35, 95% CI 0.85 to 2.15; p = 0.20). Persistence of significant symptoms at 6 weeks was lower in both arms than at 1 year (9% HAL and 29% RBL), suggesting significant deterioration in both groups over the year. Symptom score, EQ-5D-5L and Vaizey score improved in both groups compared with baseline, but there was no difference between interventions. Pain was less severe and of shorter duration in the RBL group; most of the HAL group who had pain had mild to moderate pain, resolving by 3 weeks. Complications were low frequency and not significantly different between groups. It appeared that HAL was not cost-effective compared with RBL. In the base-case analysis, the difference in mean total costs was £1027 higher for HAL. Quality-adjusted life-years (QALYs) were higher for HAL; however, the difference was very small (0.01) resulting in an incremental cost-effectiveness ratio of £104,427 per additional QALY.

CONCLUSIONS

At 1 year, although HAL resulted in fewer recurrences, recurrence was similar to repeat RBL. Symptom scores, complications, EQ-5D-5L and continence score were no different, and patients had more pain in the early postoperative period after HAL. HAL is more expensive and unlikely to be cost-effective in terms of incremental cost per QALY.

LIMITATIONS

Blinding of participants and site staff was not possible.

FUTURE WORK

The incidence of recurrence may continue to increase with time. Further follow-up would add to the evidence regarding long-term clinical effectiveness and cost-effectiveness. The polysymptomatic nature of haemorrhoidal disease requires a validated scoring system, and the data from this trial will allow further assessment of validity of such a system. These data add to the literature regarding treatment of grade II/III haemorrhoids. The results dovetail with results from the eTHoS study [Watson AJM, Hudson J, Wood J, Kilonzo M, Brown SR, McDonald A, et al. Comparison of stapled haemorrhoidopexy with traditional excisional surgery for haemorrhoidal disease (eTHoS): a pragmatic, multicentre, randomised controlled trial. Lancet 2016, in press.] comparing stapled haemorrhoidectomy with excisional haemorrhoidectomy. Combined results will allow expansion of analysis, allowing surgeons to tailor their treatment options to individual patients.

Management and outcome of gastrointestinal bleeding in patients taking oral anticoagulants or antiplatelet drugs

BACKGROUND

Non-vitamin K dependent oral anticoagulants (NOACs) significantly decrease overall major bleeding rates compared with vitamin K antagonists (VKAs) but there is conflicting evidence regarding the relative risk of gastrointestinal bleeding. Since data regarding the types, the management, and the outcome of NOAC-associated gastrointestinal bleeding are scarce, we aimed to fill this gap by comparing cases of gastrointestinal bleeding associated with NOAC, VKA, or antiplatelet therapy.

METHODS

All major gastrointestinal bleeding events documented in the prospective Dresden NOAC registry were identified, and bleeding location, lesion type, endoscopic treatment, use of blood and coagulation factor transfusion, length of stay, and in-hospital mortality were compared with historical data from a large cohort of consecutive gastrointestinal bleeding patients.

RESULTS

In the 143 NOAC therapy cases, upper gastrointestinal tract bleeding was seen in 44.1%, lower gastrointestinal tract bleeding was seen in 42.0%, and no lesion could be identified in the remaining 14.0%. In contrast, upper gastrointestinal tract bleeding was commoner in the 185 VKA therapy cases (53.0%) and in the 711 antiplatelet therapy cases (68.1%). Among cases with upper gastrointestinal tract bleeding during VKA or antiplatelet therapy, 54.1% and 61.4% respectively presented with ulcers, compared with 27.0% for NOAC therapy. In contrast, hemorrhoid bleeding was the predominant lesion type for lower gastrointestinal tract bleeding with NOAC therapy, with a rate of 33.3%, compared with 10.6% with VKA therapy and 8.7% with antiplatelet therapy. NOAC-associated gastrointestinal bleeding resulted in comparatively low resource consumption, shorter hospitalization, and low in-hospital mortality (1.6%) compared with gastrointestinal bleeding historically seen with use of VKAs (in-hospital mortality 5.6%) or antiplatelet agents (in-hospital mortality 11.9%).

CONCLUSIONS

Gastrointestinal bleeding in NOAC recipients is different from that seen with VKA or antiplatelet therapy and has a better short-term prognosis.

Effects of Topical Atorvastatin (2 %) on Posthemorrhoidectomy Pain and Wound Healing: A Randomized Double-Blind Placebo-Controlled Clinical Trial

BACKGROUND

Atorvastatin is a 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase inhibitor widely used in treatment of hypercholesterolemia and prevention of coronary heart disease and has various pleiotropic effects. In this study, the efficacy of atorvastatin emulgel (2 %) in reducing postoperative pain at rest, pain during defecation and analgesic requirement after open hemorrhoidectomy was investigated.

METHODS

A total of 66 patients with third- and fourth-degree hemorrhoids undergoing open hemorrhoidectomy were included in this prospective, double-blind, randomized controlled trial. The patients were randomly assigned to either atorvastatin emulgel or placebo immediately after surgery and then every 12 h for 14 days. The primary outcomes were intensity of pain at rest and during defecation, measured with a visual analog scale, and the analgesic requirement, measured by amount of pethidine and acetaminophen consumption, and percent of wound healing.

RESULTS

There was no significant difference in the average postoperative pain scores in the first 48 h (P _12h = 1, P _24h = 0.128 and P _48h = 0.079) after the surgery between the two groups, but at the week 1 the pain scores during defecation were considerably lower in the atorvastatin group than in placebo group (P = 0.004), which also was the same at the week 2 (P = 0.03). There was no significant difference in the average pethidine and acetaminophen (mg) administration at 12 h and 24 h between the two groups after surgery. Regarding the data about wound healing, at the week two the healing was much better in the treatment group than it was in control group and the difference was statistically significant (P = 0.04).

CONCLUSIONS

Compared with placebo, atorvastatin emulgel reduced postoperative pain at rest and on defecation and could improve the healing process after open hemorrhoidectomy.

Flavonoids as detoxifying and pro-survival agents: What's new?

The role of flavonoids in the survival machinery of cells has come in the spotlight due to the recent evidence of their effect on the relationship mitochondria-ER stress-proteasome, including the intracellular mechanisms of autophagy and apoptosis. Numerous experimental animal investigations and even human clinical studies have highlighted the major role of these natural compounds in the economy of life and their deep relationship with autotrophic organisms in the evolutionary space. Their role as anti-oxidant and oxidative stress preventive molecules has to date been investigated extensively in the literature. Despite this great amount of promising evidence, many concerns, however, remain, most of which dealing with biochemistry, bioavailability, pharmacokinetics, and interaction of flavonoids with gut microbiome, issues that make difficult any good attempt to introduce these molecules in the human healthcare systems as possible, encouraging therapeutic substances. This review tries to address and elucidate these items.

The Evaluation and Office Management of Hemorrhoids for the Gastroenterologist

PURPOSE OF REVIEW

Hemorrhoid disease is extremely common, and seldom requires surgical intervention. The vast majority of patients can be cared for in the office setting and by the gastroenterologist. This piece aims to summarize the epidemiology and pathophysiology of hemorrhoid disease, along with the proper evaluation and office-based treatment of these patients.

RECENT FINDINGS

Most GI fellowship training programs spend little time on these topics, and the recommendation has been made to include anorectal care in the GI's "core curriculum." The use of the anoscope and a proper anorectal examination are keys to evaluating these patients, and the techniques available to treat these patients are described. Often overlooked in these patients are other anorectal issues that occur alongside hemorrhoidal issues very commonly-the most common being anal fissure. Comprehensive management of all of these issues will allow all but the most severely affected patients to avoid the expense and morbidity of surgical intervention. The anatomy, etiology, pathophysiology, diagnosis, and non-surgical treatment of hemorrhoid disease are presented with the gastroenterologist in mind.

Effect of Transcutaneous Acupoint Electrical Stimulation on Post-Hemorrhoidectomy-Associated Pain, Anxiety, and Heart Rate Variability: A Randomized-Controlled Study

Hemorrhoidectomy is the current best treatment for severe hemorrhoids, but it causes significant postoperative pain and anxiety, which is associated with heart rate variability (HRV). Transcutaneous acupoint electrical stimulation (TAES) was assumed to alleviate pain and anxiety, and modify the autonomic nervous system. This study aimed to examine the effects of TAES intervention on postoperative pain, anxiety, and HRV in patients who received a hemorrhoidectomy. A randomized-controlled trial with five repeated measures was conducted. The TAES group ( n = 39) received four 20-min sessions of electrical stimulation at chengshan (BL57) and erbai (EX-UE2) after hemorrhoidectomy, whereas the control group ( n = 41) did not. Data were collected using Visual Analogue Scale (VAS), State Anxiety Inventory (STAI), and HRV physiological signal monitor. TAES resulted in a significant group difference in pain scores, anxiety levels, and some HRV parameters. The findings indicate that TAES can help reduce pain and anxiety associated with hemorrhoidectomy. TAES is a noninvasive, simple, and convenient modality for post-hemorrhoidectomy-associated pain control and anxiety reduction.

A Randomized Controlled Trial Comparing Laser Intra-Hemorrhoidal Coagulation and Milligan-Morgan Hemorrhoidectomy

PURPOSE

To compare laser intra-hemorrhoidal coagulation with Milligan-Morgan (MM) hemorrhoidectomy.

METHOD

Patients with symptomatic grade II or III internal hemorrhoids according to the Goligher's classification (refractory to medical treatment) were enrolled in this double-blinded randomized controlled trial study. In the laser group, hemorrhoidal columns were coagulated using a 980-nanometer (nm) radial laser emitting fiber (three, 15-W pulses of 1.2 s each, with 0.6-s intervals). Operative time, postoperative pain and complications, and recovery or resolution of symptoms were measured. Patients were followed up for at least one year for evaluating healing, resolution of symptoms, and late complications.

RESULTS

Postoperative pain scores (at 12, 18, and 24 hr after surgery) were significantly lower in the laser group compared with the MM group (p <.01). The operative time and intra-operative blood loss were more in the MM group (p <.001). The administration of analgesics was significantly reduced in the laser group (p <.05). Two patients in the laser group were presented with thrombosis of external hemorrhoid 7-10 days after the procedure, which was resolved with medical treatment, but no patients in the MM group developed hemorrhoidal thrombosis (p >.05). One-year follow-up showed comparable results in terms of the resolution of symptoms and sustainable cure.

CONCLUSIONS

Intra-hemorrhoidal coagulation with 980-nm diode laser reduces postoperative pain, intra-operative bleeding, and administered analgesics with a comparable resolution rate of hemorrhoid symptoms. However, for the patients who experience complications, such as hemorrhoidal thrombosis, the overall pain may be equivalent to or even worse than conventional hemorrhoidectomy.

Treatment of hemorrhoids with individualized homeopathy: An open observational pilot study

Aim:

Controversies and disagreement exist on conventional treatment strategies of hemorrhoids due to relapse, inefficacy, and complications. We intend to evaluate the role of individualized homeopathic treatment in hemorrhoids.

Materials and Methods:

In this prospective, open, observational trial, hemorrhoids patients were treated using five standardized scales measuring complaints severity and anoscopic score. It was conducted at two homeopathic hospitals in India, during from mid-July 2014 to mid-July 2015. Patients were intervened as per individualized homeopathic principles and followed up every month up to 6 months.

Results:

Total 73 were screened, 52 enrolled, 38 completed, 14 dropped out. Intention to treat population (n: = 52) was analyzed in the end. Statistically significant reductions of mean bleeding (month 3: −21.8, 95% confidence interval [CI]: −30.3, −13.3, P: < 0.00001, d = 0.787; month 6: −25.5, 95% CI −35.4, −15.6, P: < 0.00001, d = 0.775), pain (month 3: −21.3, 95% CI −28.6, −14.0, P: < 0.00001, d = 0.851; month 6: −27.6, 95% CI −35.6, −19.6, P: < 0.00001, d = 1.003), heaviness visual analog scales (VASs) (month 3: −8.1, 95% CI −13.9, −2.3, P: = 0.008, d = 0.609; month 6: −12.1, 95% CI −19.1, −5.1, P: = 0.001, d = 0.693), and anoscopic score (month 3: −0.4, 95% CI −0.6, −0.2, P: < 0.0001, d = 0.760; month 6: −0.5, 95% CI −0.7, −0.3, P: < 0.0001, d = 0.703) were achieved. Itching VASs reduced significantly only after 6 months (−8.1, 95% CI −14.6, −1.6, P: = 0.017, d = 0.586). No significant lowering of discharge VASs was achieved after 3 and 6 months.

Conclusion:

Under classical homeopathic treatment, hemorrhoids patients improved considerably in symptoms severity and anoscopic scores. However, being observational trial, our study cannot provide efficacy data. Controlled studies are required. Trial Reg. CTRI/2015/07/005958.

Anorectal emergencies

Anorectal emergencies refer to anorectal disorders presenting with some alarming symptoms such as acute anal pain and bleeding which might require an immediate management. This article deals with the diagnosis and management of common anorectal emergencies such as acutely thrombosed external hemorrhoid, thrombosed or strangulated internal hemorrhoid, bleeding hemorrhoid, bleeding anorectal varices, anal fissure, irreducible or strangulated rectal prolapse, anorectal abscess, perineal necrotizing fasciitis (Fournier gangrene), retained anorectal foreign bodies and obstructing rectal cancer. Sexually transmitted diseases as anorectal non-surgical emergencies and some anorectal emergencies in neonates are also discussed. The last part of this review dedicates to the management of early complications following common anorectal procedures that may present as an emergency including acute urinary retention, bleeding, fecal impaction and anorectal sepsis. Although many of anorectal disorders presenting in an emergency setting are not life-threatening and may be successfully treated in an outpatient clinic, an accurate diagnosis and proper management remains a challenging problem for clinicians. A detailed history taking and a careful physical examination, including digital rectal examination and anoscopy, is essential for correct diagnosis and plan of treatment. In some cases, some imaging examinations, such as endoanal ultrasonography and computerized tomography scan of whole abdomen, are required. If in doubt, the attending physicians should not hesitate to consult an expert e.g., colorectal surgeon about the diagnosis, proper management and appropriate follow-up.
