[Usefulness and safety of observing anorectal lesions by colon capsule endoscopy].

We investigated the findings of rectoanal lesions in 190 patients who underwent colon capsule endoscopy (CCE) at our hospital. Internal hemorrhoids were observed in 70 (36.8%) patients and rectal polyps in 19 (10%) patients. When conventional endoscopy (colonoscopy and double balloon endoscopy) was considered the gold standard, the sensitivity and specificity of rectal polyps were 75% and 93.4%, respectively, and those of internal hemorrhoids were 88.9% and 92.7%, respectively. The prevalence of constipation was significantly higher in the false-negative group for internal hemorrhoids, and the colonic transit time was significantly shorter in the false-negative and false-positive groups for rectal polyps. No adverse events occurred in any of the patients. CCE might be a useful and safe examination method for rectoanal lesions.

Perianal complications in puerperium and associated risk factors

Introduction: Puerperium is defined as the period of about 6 weeks after childbirth during which the mother's reproductive organs return to their original nonpregnant condition. Perianal problems, including constipation, hemorrhoids, and fissure, are among the most common digestive complications among women in puerperium, observed in about 30 to 50 percent of women. Considering this great prevalence and the paucity of similar research in this aspect in an Indian population, the present study was done to assess the prevalence of perianal problems seen in puerperium and the risk factors associated with it. Methods: This was a prospective observational cohort study done over the span of 3 years on 902 puerperal women. A self-structured questionnaire covered detailed history and per-rectal and proctoscopy examination. Patients were followed up telephonically for regression of perianal problems post management. Results: The total prevalence of all the perianal problems in puerperium encountered in the present study, out of 902 subjects, was 36.3% (327 subjects). The perianal problems encountered were fissure in 185 patients (20.5%) followed by hemorrhoids in 110 patients (12.2%), perianal episiotomy infections in 25 patients (2.8%), and perineal tears in 7 patients (0.8%). On comparative analysis, positive family history, macrosomia, past history of perianal diseases, and second stage of labour > 50 minutes showed a higher prevalence in the perianal disease group as compared with the healthy group. Out of these, positive family history of perianal diseases (p= 0.015) and past history of perianal diseases (p= 0.016) were statistically significant. The percentage of multipara with hemorrhoids was more when compared to primipara (p= 0.01), patients who had a past history of any perianal disease have a higher chance of hemorrhoids during puerperium (p= 0.00). Patients with constipation in pregnancy have higher chance of hemorrhoids in pregnancy (p= 0.00). Patients who had a past history of any perianal disease had higher chance of fissure during puerperium (p= 0.00). A total of 27.74% of the study subjects with macrosomic babies had fissure in their puerperal period which on comparison with patients with non macrosomic babies was only 19.22%, which was statistically significant (p= 0.02). Conclusion: Constipation, hemorrhoids, and anal fissures are the most common perianal problems in postpartum period causing significant reduction in the quality of life of those afflicted with them.

Rubber band ligation versus coagulation for the treatment of haemorrhoids: a meta-analysis of randomised controlled trials.

Non-surgical therapies have the advantage of lower postoperative pain and complication rates compared with surgical therapies. Rubber band ligation and coagulation are two kinds of non-surgical therapies. The aim of this study is to compare the clinical outcomes of rubber band ligation and coagulation. A systematic review was conducted to identify randomised clinical trials that compare rubber band ligation and coagulation treatments for haemorrhoids. PubMed and Web of Science were searched, from inception to April 30th,2022. Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed. Fifty-nine studies were identified. Nine trials met the inclusion criteria. All trials were of moderate methodological quality. No significant difference was found between rubber band ligation and coagulation in terms of efficacy rate, postoperative prolapse rate, recurrence rate and postoperative urine retention rate after treatment. Patients undergoing rubber band ligation had higher postoperative pain rate and lower postoperative bleeding rate than patients undergoing coagulation. The subgroup analysis showed that there was no significant difference between rubber band ligation and infrared coagulation or non-infrared coagulation in terms of efficacy rate, postoperative bleeding and postoperative urine retention rate after treatment. Patients undergoing rubber band ligation had a higher postoperative pain rate than patients undergoing infrared coagulation or non-infrared coagulation. We believe that coagulation for haemorrhoids still has a good future. PROSPERO registration number CRD42022311281.

Local anaesthetic for pain post rubber band ligation of haemorrhoids: a prospective, single-blinded randomised controlled trial.

BACKGROUND: Rubber band ligation (RBL) is a widely accepted intervention for the treatment of haemorrhoids. However, post procedure pain is a common complaint. The aim of this study was to determine whether the addition of local anaesthetic (LA) to the haemorrhoid pedicle base, post RBL, aids in reducing early post-procedure pain. Additionally, to compare perceived perianal numbness, oral analgesia usage and total consumption, and adverse events. METHODS: This study was a prospective, single-blinded randomised controlled trial. Patients were recruited from colorectal clinics in two Australian hospitals between 2018-2019. Patients randomised to the intervention (LA) group received 2mls bupivacaine 0.5% with adrenaline 1:200,000 to each haemorrhoid base. Patients in the control group were not administered LA. Pain scores were recorded over 48 h using visual analogue scales. Analgesia consumption was documented and other secondary objectives were recorded dichotomously (yes/no). RESULTS: At 1 h post-procedure, patient reported pain scores were significantly lower in the LA group compared to the control group (p = 0.04). There were no significant differences in pain scores between the groups at 4, 24 or 48 h. Additionally, there were no significant differences between groups with respect to oral analgesia usage, perianal numbness or adverse events. CONCLUSIONS: LA to the haemorrhoid pedicle post RBL may significantly reduce early post procedure pain without any increased risk of adverse effects.

Diverticulosis Is Associated With Internal Hemorrhoids on Colonoscopy: Possible Clues to Etiology.

Hemorrhoids are a common but poorly understood gastrointestinal condition.1 Bowel habits and fiber consumption are frequently cited as risk factors for hemorrhoids, but research has been inconclusive.2 Recent genome-wide association studies (GWAS) have suggested an association between diverticular disease and hemorrhoids.3 We sought to investigate the association between colonic diverticulosis and internal hemorrhoids to validate the prediction from the GWAS.

Doppler ultrasound testing suggests hemorrhoids in females may be a consequence of impaired blood flow Associated with pelvic organ prolapse

Abstract Background It has been observed that there is a high incidence of hemorrhoids in female patients with pelvic organ prolapse. Also, in these patients, hemorrhoidal disease improves after the surgical correction of the pelvic organ prolapse. Objective Our hypothesis was that a cause-effect relationship between pelvic organ prolapse, and hemorrhoids might be the key. The objective of this study was to find an element which connects these two conditions. Study Design We conducted a pilot study which consisted of two parts. An initial part, in which we asked several patients with grades III and IV pelvic organ prolapse and hemorrhoids, who have undergone surgery for prolapse, to determine the impact of the surgical restoration of the prolapsed organs on their hemorrhoidal disease. For the second part, on several patients with uncorrected uterine prolapse grades III and IV, we determined the resistive index of the hemorrhoidal branches within the rectal wall before and after manual reduction of the prolapse. Results First, more than 50% of patients who underwent uterine prolapse correction described an improvement of their hemorrhoidal disease of over 50%. Second, the resistive index of the hemorrhoidal branches was significantly lower after manual reduction of the prolapse. We consider that obstructed veins due to pelvic organ prolapse might induce the dilation of the hemorrhoids. The direct measurement of the resistive index of the hemorrhoidal branches allows us to directly assess the increased resistance in the rectal vascular system. Conclusion Venous stasis and impaired vascular flow might be the pathophysiological explanation for the association between pelvic organ prolapse and hemorrhoids. In these patients, the pathogenic treatment should aim at the restoration of a normal blood flow (prolapse surgical cure) instead of focusing on hemorrhoids only.(AU)

Anorectal Melanoma-Brownish Black Mass Not Always a Hemorrhoid.

The non-specific clinical symptoms of anorectal brownish-black mass do not help to differentiate colorectal cancer, hemorrhoids, rectal ulcers which result in a delayed diagnosis or lead to inadequate management of lethal anorectal melanoma. Primary malignant melanoma of the anorectal region is an uncommon tumor, constituting approximately 1% of anal canal tumors which may be misdiagnosed clinically as hemorrhoids. Because of aggressive behavior and poor prognosis, efficient and prompt diagnosis is required in these cases. We report 2 cases of this rare tumor.

The Potential Link between Episodes of Diverticulitis or Hemorrhoidal Proctitis and Diets with Selected Plant Foods: A Case-Control Study.

Diverticulitis and hemorrhoidal proctitis in the population are significant public health problems. We studied the potential association between the intake of certain plant foods and diverticulitis or hemorrhoidal episodes through a case-control study including 410 cases and 401 controls. We used a semiquantitative food frequency questionnaire. The intake was additionally quantified according to a 24 h recall. The plant foods or derived food products were categorized by their main chemical components into ethanol, caffeine/theine/theobromine, capsaicin, alliin, acids, eugenol, and miscellaneous foods such as curcumin. The mean score for overall intake of plant foods under consideration was 6.3 points, and this was significantly higher in cases (8.5) than in controls (4.1). Overall intake was similar in cases presenting with diverticulitis or hemorrhoidal proctitis. Cases had 13 times the odds of being in the upper quartile for overall intake (>7 points), compared to controls. Explanatory logistic regression models showed that the strongest association with diverticulitis and hemorrhoidal proctitis was shown by the chemical food group of capsaicin, followed by ethanol, eugenol, caffeine/theine/theobromine, and acids. Neither alliin nor miscellaneous food groups showed any association. High, frequent consumption of capsaicin, followed by ethanol, eugenol, caffeine/theine/theobromine, and acids increase the risk of diverticulitis and hemorrhoidal proctitis.

Venous leg symptoms, ecchymosis, and coldness in patients with peripheral varicose vein: A multicenter assessment and validation study (VEIN-VIOLET study).

OBJECTIVES: We aimed to evaluate peripheral varicose vein symptoms including ecchymosis and coldness by using the Venous Insufficiency Epidemiological and Economic Study-Quality of Life/Symptoms (VEINES-QoL/Sym) questionnaire. METHODS: A total of 1120 patients were enrolled to the analysis after the exclusion of 199 patients who did not match the inclusion criteria. Patients were asked to answer the VEINES-Sym questionnaire and questions about ecchymosis and coldness. Scores of ecchymosis and coldness were calculated similar to VEINES-Sym questionnaire. Classifications of peripheral varicose vein were made according to the clinical part of clinical, etiological, anatomical, and pathophysiological classification system and patients with grade 2 or higher were considered as positive for peripheral varicose vein. RESULTS: Frequency of symptoms present in the VEINES-Sym instrument, ecchymosis and coldness were significantly higher in patients with peripheral varicose vein. Mean score of each symptom was significantly lower in peripheral varicose vein patients including scores of ecchymosis and coldness. Logistic regression analysis revealed that presence of hemorrhoids and all symptoms in VEINES-Sym questionnaire except restless leg were significantly and independently associated with peripheral varicose vein. Besides, ecchymosis (odds ratio: 2.04, 95% confidence interval: 1.34-3.08, p = 0.008) but not coldness was significantly and independently associated with peripheral varicose vein. There was also significant correlation of VEINES-Sym score with ecchymosis (r = 0.43, p < 0.001) and coldness (r = 0.47, p < 0.001). CONCLUSIONS: Venous leg symptoms present in VEINES-Sym questionnaire except restless legs, presence of hemorrhoids and ecchymosis are significantly and independently associated with peripheral varicose vein. Not only ecchymosis but also coldness has shown an independent association with total VEINES-Sym score.

Aberrant expression for microRNA is potential crucial factors of haemorrhoid.

BACKGROUND: Haemorrhoids occur commonly and frequently in the human digestive system. There are diverse causes of haemorrhoids and their in-depth pathogenesis is still currently unclear. METHODS: In this study, we explored haemorrhoids from an epigenetics perspective by employing RNA-Seq for comprehensive and in-depth analysis of the differences in microRNA (miRNA) transcripts between haemorrhoidal tissue and normal tissue in 48 patients with Grade II and above haemorrhoids. RESULTS: The results showed that 9 miRNAs were significantly upregulated (ratio > 3.5 and P-value < 0.01) and 16 miRNAs were significantly downregulated (ratio > 0.6 and P-value < 0.01) in haemorrhoid tissue. Subsequently, target gene prediction results showed that there were 184 potential target genes of significantly upregulated miRNAs (common to both TargetScan7.1 and MirdbV5 databases) and there were 372 potential target genes of significantly downregulated miRNAs. Gene ontology analysis results showed that the target genes of differentially expressed miRNAs in haemorrhoids are involved in regulating "cell composition" and "protein binding". Lastly, KEGG search found that the differentially expressed miRNAs that are associated with the occurrence of haemorrhoids mainly regulate the activity of endocytosis and the synaptic vesicle cycle. CONCLUSIONS: In summary, the results of high-throughput RNA-Seq screening suggested that the occurrence of haemorrhoids may be intimately associated with aberrant miRNA transcription, resulting in aberrant target gene expression and an imbalance in certain signal transduction pathways.

Hemorrhoidal disease and chronic venous insufficiency: Concomitance or coincidence; results of the CHORUS study (Chronic venous and HemORrhoidal diseases evalUation and Scientific research).

BACKGROUND AND AIM: The CHORUS study (Chronic venous and HemORrhoidal diseases evalUation and Scientific research) was conducted to provide data on patients presenting with hemorrhoidal disease (HD) in clinical practice and to explore the frequency with which it coexists with chronic venous disease (CVD) and shared risk factors. METHODS: This international, noninterventional study enrolled adult patients attending a consultation for hemorrhoidal complaints. The questionnaire completed by physicians established the subjects' demographic and lifestyle characteristics and collected information on HD grade and symptoms and signs of CVD. RESULTS: A total of 5617 patients were analyzed. Symptoms commonly reported were bleeding (71.8%), pain (67.4%), swelling (55.0%), itching (44.1%), and prolapse (36.2%). Multivariate analysis revealed the variables with the strongest association with HD severity were older age, higher CVD CEAP (Clinical manifestations, Etiologic factors, Anatomic distribution of disease, and underlying Pathophysiology) class, constipation, and male gender (all P < 0.0001). Elevated BMI was a risk factor for HD recurrence. Among women, number of births had a significant association with both HD grade and recurrence. The presence of CVD, reported in approximately half the patients (51.2%), was strongly associated with advanced grade of HD (P < 0.0001). Treatments most commonly prescribed were venoactive drugs (94.3%), dietary fiber (71.4%), topical treatment (70.3%), analgesics (26.3%), and surgery (23.5%). CONCLUSIONS: CHORUS provides a snap shot of current profiles, risk factors, and treatments of patients with HD across the globe. The coexistence of HD and CVD in more than half the study population highlights the importance of examining for CVD among patients with a hemorrhoid diagnosis, particularly when shared risk factors are present.

Dietary habits associated with internal hemorrhoidal disease: a case-control study.

BACKGROUND: Pathophysiology of the internal hemorrhoidal disease is poorly understood but seems to be multifactorial. Some types of food and lifestyle have been assumed to increase the risk of internal hemorrhoidal disease.  Aims: To identify alimentary habits that are associated with internal hemorrhoidal disease. METHODS: Fifty patients and 50 healthy controls matched for age and sex were enrolled in a case-control study. Food intake of patients and controls was assessed by a nutritionist using the 72-hour recall method and the food frequency questionnaire. Data regarding their eating behavior were also collected using an eating behavior questionnaire. RESULTS: Mean age of patients was 42 ± 11.8 years with a female to male ratio of 1.17. Prolapse and anal pain were the most common presenting symptoms. Constipation was found in almost all patients. High-fiber foods were less often consumed by patients than by controls with the difference being significant for vegetables, fruits and cereals. Regarding spicy aliments, consumption of pepper and chili powder was found to be significantly less frequent in patients than in controls.  Multivariate analysis revealed daily fiber intake < 12 g (OR 7.08; 95%CI 1.24 - 40.30; p=0.027) and daily water intake < 2L (OR 8.68; 95%CI 3.07 - 24.51; p<0.001) significantly increase the risk of internal hemorrhoidal disease. CONCLUSIONS: Internal hemorrhoidal disease was more frequently observed in patients with low-fiber diet and a reduced water intake. These dietary habits were described as precipitating factors of constipation which was found in almost all patients.

Dose-volume analysis of predictors for acute anal toxicity after radiotherapy in prostate cancer patients.

BACKGROUND: This study aimed to evaluate the clinical and dosimetric factors predictive of acute anal toxicity (AAT) after radiotherapy in prostate cancer (PCa) patients with or without hemorrhoids. METHODS: We analyzed data from 347 PCa patients (248 cases treated from July 2013 to November 2017 for training cohort and 99 cases treated in 2018 for validation cohort) treated with pelvic radiotherapy at a single institution. Anal canal dose-volume histogram was used to determine the prescribed dose. Univariate and multivariate analyses were used to evaluate the risk of AAT as a function of clinical and dosimetric factors. RESULTS: Totally, 39.5% (98/248) and 31.3% (31/99) of the PCa patients developed AAT in training and validation cohorts, respectively. The incidence of AAT was much higher in patients with hemorrhoids than in those without hemorrhoids in both training and validation cohorts. Hemorrhoids and volume received more than 20 Gy (V20) were valuated as independent factors for predicting AAT in training cohort. Similar results were also observed in our validation cohort. The combination of hemorrhoids and high anal canal V20 (> 74.93% as determined by ROC curves) showed the highest specificity and positive predictive values for predicting AAT in both training and validation cohorts. CONCLUSIONS: AAT occurs commonly in PCa patients with hemorrhoids during and after pelvic radiotherapy. Hemorrhoids and anal canal V20 are independent predictors of AAT. These factors should be carefully considered during treatment planning to minimize the incidence of AAT.

Effect of Genetic Factors on the Etiopathogenesis of Thrombosed Hemorrhoidal Disease.

OBJECTIVE: The aim of this study is to investigate whether genetic factors known to increase thrombosis risk play a role in the etiopathogenesis of thrombosed hemorrhoidal disease. Methods: Genomic DNA from patients with thrombosed hemorrhoidal disease was analyzed for the presence of factor V Leiden, prothrombin G20210A, methylenetetrahydrofolate reductase C677T, and methylenetetrahydrofolate reductase A1298C mutations. Results: No significant differences were found in the allele frequencies of factor V Leiden, prothrombin G20210A, methylenetetrahydrofolate reductase C677T, and methylenetetrahydrofolate reductase A1298C mutations between patients with thrombosed hemorrhoidal disease and controls (p 0.05). Moreover, there were no significant differences in the genotype (heterozygous and homozygous mutations) of factor V Leiden, prothrombin G20210A, methylenetetrahydrofolate reductase C677T and A1298C mutations between patients with thrombosed hemorrhoidal disease and controls (p 0.05). Conclusions: Our findings indicate that mutations associated with venous thromboembolism do not play a role in the etiopathogenesis of thrombosed hemorrhoidal disease; however, several environmental, mechanical, and hemodynamic factors may contribute to the etiopathogenesis of hemorrhoidal disease.

Fecal evacuation disorders in anal fissure, hemorrhoids, and solitary rectal ulcer syndrome.

The causative factors for hemorrhoids, anal fissure, and solitary rectal ulcer syndrome (SRUS) are poorly understood. The study was done to identify the prevalence of fecal evacuation disorders in patients with anal fissure, hemorrhoids, and SRUS using anorectal manometry (ARM). Retrospective analysis of ARM data from three centers across India was done. Baseline demographic details and symptoms pertaining to bowel movements were noted. Limited colonoscopy details pertaining to hemorrhoids, fissure-in-ano, and SRUS were noted. The patients were divided into two groups-group I (those with fissure, hemorrhoids, or solitary rectal ulcer) and group II (normal study). ARM parameters of resting anal pressure, squeeze pressure, dyssynergic defecation, and abnormal balloon expulsion were compared between the two groups. Sub-analysis was done for ARM metric differences between those with hemorrhoids, chronic fissure, and SRUS. Appropriate statistical tests were used. A p-value of < 0.05 was considered significant. There were more men in group I (87%; p-value 0.01) with a higher resting anal pressure (80 vs. 69 mmHg, p-value 0.03). Functional evacuation disorders (p < 0.0001), dyssynergic defecation (77.2% vs. 46.8%, p < 0.0001) and abnormal balloon expulsion (66.7% vs. 20.3%, p < 0.0001) were significantly higher in group I. These were significantly more common in patients with anal fissure and SRUS compared to those with hemorrhoids (p-value 0.028). Functional evacuation disorders are frequently noted in patients with hemorrhoids, anal fissure, and SRUS.

Rethinking What We Know About Hemorrhoids.

Although hemorrhoids are responsible for considerable economic cost and personal suffering, they have received surprisingly little research attention. In the United States, hemorrhoids are the third most common outpatient gastrointestinal diagnosis with nearly 4 million office and emergency department visits annually. The etiology of hemorrhoids is speculative. A low-fiber diet and constipation have historically been thought to increase the risk for hemorrhoids, but not proven. Symptoms commonly attributed to hemorrhoids include bleeding, pain, pruritus, fecal seepage, prolapse, and mucus discharge. Research has found that these symptoms were equally reported by patients with and without hemorrhoids. Medical therapies for hemorrhoids have not been formally studied except for fiber where the results have been inconsistent. A number of office-based interventions such as rubber band ligation and infrared coagulation are widely used and economically favorable for practitioners. Surgical procedures are effective at eliminating hemorrhoids but may be painful. Given the burden of disease and numerous gaps in our understanding, the time has come for targeted research to understand the cause, symptoms, and best treatment for patients with symptomatic hemorrhoids.

Hemorrhoids: what are the options in 2018?

PURPOSE OF REVIEW: Efforts continue to improve the treatment of patients with symptomatic hemorrhoidal disease by interventions designed to improve efficiency and effectiveness, including by reducing intraoperative and postoperative pain, decreasing operating times, minimizing blood loss and controlling symptoms and recurrence rates. Simultaneously, there are also renewed efforts to minimize the number of patients who will require procedural intervention by focusing on conservative measures that encourage better bowel regulation and habits. The purpose of this brief report is to review the current status of the diagnosis and treatment of patients with hemorrhoidal disease. Overall, new procedures or procedural refinements to existing techniques continue to be introduced with promising short-term outcomes - at least in some instances. In most instances, long-term follow-up or equivalency data are still being accumulated such that a definitive, unequivocal answer to what is truly the best alternative to traditional hemorrhoidectomy remains controversial. One of the challenges is heterogeneity as regards diagnosis, intervention and, especially, outcomes measures such that comparing therapies is too difficult. A recent initiative to standardize metrics has promise. RECENT FINDINGS: Recent studies largely appear to suggest that conservative treatment approaches and managing patient expectations are critically important in which a primary objective should be to minimize the progression to symptomatic disease and complications in patients who are diagnosed with hemorrhoids. The pace of change as regards the development of new or improved surgical techniques appears may be accelerating. SUMMARY: Progress is being made and the knowledge base is being expanded as regards the treatment options for patients with hemorrhoids and expected outcomes. A key initiative to standardize the approaches to diagnosis and treatment about staging, procedural interventions and outcomes will facilitate comparative analytics, if successful.
