Development of a low-cost simulator for training in hemorrhoidal ligation

Introduction: Rubber band ligation is a minimally invasive outpatient hemorrhoid treatment with low cost, low complication rates, and rapid realization. It is performed with the aid of an anoscope and uses a rubber ring that surrounds the hemorrhoidal nipple, causing compression of the vascular structures of the tissue, leading to necrosis and remission of the hemorrhoid. No device for training this essential procedure for treating this pathology has been identified in the literature. Therefore, we aim to develop a low-cost simulator for training hemorrhoidal rubber ligation. Methods: The model was constructed using PVC pipe wrapped in neoprene fabric. Hemorrhoidal nipples and the pectineal line were also simulated using fabric and sewing threads. The procedure is performed with conventional anoscope and ligature forceps. Conclusion: The device in question is a low-cost simulation model designed to train the skills required to perform a rubber band ligation and review the basic anatomy of the anal canal during anoscopy. Given these qualities, the model can be used for academic training due to its low cost and simplicity of application. (AU)

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.

Identification and reporting of anal pathology during routine colonoscopies

The gold-standard procedure for anal canal examination is anoscopy. Nonetheless, patients are referred for a colonoscopy for many reasons, and a routine exam might provide an opportunity to diagnose anal pathologies, such as hemorrhoids, anal fissures, anal polyps, condylomas, and anal squamous cell carcinoma. It is important to know the main features of these conditions and relevant information to report in order to help guide patient treatment and follow-up.

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)

A morphometric analysis of pathological alterations in hemorrhoidal disease versus normal controls: a controlled trial

Objective: Until today, the true pathophysiology of hemorrhoidal disease (HD) has not yet been unraveled. More and more evidence guides us towards the hypothesis that reduced connective tissue stability is associated with a higher incidence of hemorrhoids. The present study aimed to compare the quantity and quality of collagen, and vessel morphometrics, in patients with symptomatic HD compared with normal controls. Methods: Twenty-two samples of grade III and grade IV HD tissue from patients undergoing a hemorrhoidectomy between January 2004 and June 2015 were included in the study group. Samples of 15 individuals without symptomatic HD who donated their body to science and died a natural death served as controls. The quantity and quality of anal collagen, and anal vessel morphometrics were objectified. The quality of collagen was subdivided in young (immature) and old (mature) collagen. Results: Patients with HD had an increased percentage of total anal collagen (62.1 ± 13.8 versus 18.7 ± 14.5%; p = 0.0001), a decreased percentage of young collagen (0.00009 ± 0.00008 versus 0.0008 ± 0.0008%; p = 0.001), and a smaller surface area of the anal vessels (795.1 ± 1215.9 micrometre2 versus 1219.0 ± 1976.1; p = 0.003) compared with controls. The percentage of old collagen did not differ between the control and study groups (0.588 ± 0.286% versus 0.389 ± 0.242%; p = 0.06). Conclusion: The outcomes of the present study suggest that alterations in anal collagen composition may play a role in the formation of hemorrhoids. (AU)

recurrent hemorrhoids-efficacy, utility and initial experience with the use of stapled hemorrhoidopexy in recurrent hemorrhoids

Overview: Hemorrhoidal disease (HD) is a common surgical disorder. The treatment modalities can be surgical or nonsurgical. Every surgical option has its own indications and limitations. Postsurgical symptomatic recurrence rates are low and vary between different techniques. The ideal way to deal with recurrent HD is not clear. Material and Methods: The present prospective case series enrolled a total of 87 patients (54male/33 female). Thirteen out of 87 patients (15%) had history of previous intervention for HD. Amodification of the standard technique was adopted for patients with recurrent HD. A mean follow-up of 22 months was achieved. Results: Stapled hemorrhoidectomy (SD)was performedin13patientswho had historyof previous surgical intervention for HD. There were no adverse events related to the technique. Patients with recurrent HD had severe pain scores with SH as compared to patients who underwent SH at the first time. There were no wound related complications. Conclusion: Stapled hemorrhoidectomy can be performed easily and offers good results in patients with recurrent HD. (AU)

Selective hemorrhoidal dearterialization with high mucopexy in the surgical treatment of hemorrhoidal disease

The doppler-guided transanal hemorrhoidal dearterialization technique associated with mucopexy is a noninvasive surgical option used to treat hemorrhoidal disease (HD). Objective: To compare and analyze the results using a variation of the doppler-guided transanal hemorrhoidal dearterialization technique with the technique of selective hemorrhoidal dearterialization with high mucopexy in the treatment of HD. Method: A total of 292 patients who underwent surgical treatment for grade II, III and IV HD from March 2012 to December 2017 were studied. From this total, 110 (37.6%) patients underwent a conventional doppler-guided transanal hemorrhoidal dearterialization with mucopexy (CD), and 182 (62.3%) underwent selective hemorrhoidal dearterialization with highmucopexy (SHeLF). In the group of patients undergoing CD, 4 patients (3.64%) had grade II HD, 82 (74.55%) grade III, and 24 (21.82%) grade IV. In the group submitted to SHeLF, 18 (9.89%) patients had grade II HD, 86 (47.25%) had grade III, and 65 (35.71%) had grade IV. The same surgeon operated all patients under spinal anesthesia. In patients undergoing CD, six arterial branches have been dearterialized, while in patients undergoing SHeLF, the hemorrhoidary nipples submitted to a dearterialization were selected (from 1 to 5) by intraoperative evaluation followed by high rectal mucopexy. In the postoperative period, the following parameters were evaluated: pain, tenesmus, bleeding, and recurrence. Moderate results to severe pain was a postoperative complaint reported by 13 (11.82%) patients undergoing CD, and by 19 (10.44%) undergoing SHeLF. Intense tenesmus was reported by 26 (23.64%) patients undergoing CD and by 7 (3.85%) undergoing SHeLF. Three patients (2.73%) undergoing CD and 1 (0.55%) undergoing SHeLF evolved with postoperative bleeding. One patient (0.55%) in the group undergoing CD required surgical review of hemostasis. Six patients (5.45%) who underwent CD and 8 (4.39%) who underwent SHeLF were reoperated due to disease recurrence. Conclusion: Comparing statistics, patients undergoing the SHeLF technique have less postoperative pain, tenesmus and postoperative bleeding when compared with CD. (AU)

Clinical efficacy of medicinal leech therapy in treating third- and fourth-degree hemorrhoids / Eficácia clínica da hirudoterapia no tratamento de hemorroidas de terceiro e quarto graus

Abstract Objectives Hemorrhoids are characterized by bleeding, mucous discharge, itching, pain, and prolapse. This condition is known as bawaseer in Unani medicine, and Hirudinaria granulosa has been used for its treatment in Irsal-e Alaq, or medicinal leech therapy (MLT), for centuries. Hirudinaria granulosa with antithrombotic and antiinflammatory action is used in the treatment of chronic venous disease and hemorrhoids. The present study was aimed to investigate the efficacy of MLT in third and fourth-degree hemorrhoids. Methods A single-centre prospective, clinical trial with a pre and postanalysis design was conducted at the hospital of the National Institute of UnaniMedicine. Twenty male and female patients, with a mean age of 38 years, presenting moderate symptoms assessed with the colorectal evaluation of clinical therapeutics scale (CORECTS) questionnaire were included in the study. Hirudinaria granulosa were applied around the pile mass for 15 minutes weekly, for 4 weeks. The efficacy of the treatment was measured by an objective and subjective assessment using the CORECTS. Results When analyzed by the clinician, MLT reduced the symptoms' severity score in the following domains: pain (55% improvement; p < 0.001); anorectal itching (30% improvement; p < 0.10); and bleeding (10% improvement; p < 0.7963). Significant improvement (p < 0.001) was reported in the CORECTS score in relation to pain (44.09% improvement; p < 0.001), itching (38.55% improvement; p < 0.001), swelling (44% improvement; p < 0.001), bleeding (17.28% improvement; p < 0.007), discomfort (34.01% improvement; p < 0.001), and wellbeing (32.35 % improvement; p < 0.001), giving an average overall opinion on the therapy of 4/10. Conclusion The results of the study albeit smaller in sample size show that MLT is an effective and safe therapeutic option in reducing the symptoms of 3rd and 4th degree haemorrhoids.

Conclusão Os resultados do estudo, embora com tamanho de amostra pequeno, mostram que a hirudoterapia é uma opção terapêutica eficaz e segura na redução dos sintomas de hemorroidas de terceiro e quarto graus.

Trombectomía más fleboextracción: una técnica alternativa en el manejo de la enfermedad hemorroidal externa trombosada / Thrombectomy combined with vein stripping: An alternative technique to treat thrombosed external hemorrhoid disease

Resumen Objetivo: Evaluar los resultados de la trombectomía más fleboextracción como alternativa en el manejo de la enfermedad hemorroidal externa trombosada. Materiales: Estudio observacional, cuantitativo, retrospectivo, transversal y descriptivo de los pacientes que consultaron y se sometieron a la trombectomía más fleboextracción como técnica alternativa en el manejo de la enfermedad hemorroidal externa trombosada en el servicio de coloproctología del Hospital Militar Central desde el primero de enero de 2014 hasta el 31 de diciembre de 2016. Resultados: Se encontró que 197 pacientes consultaron por hemorroides externas trombosadas, el 71 % eran hombres y el promedio de edad para el grupo de manejo conservador fue de 48,5 años, frente al promedio del grupo de manejo quirúrgico, que fue de 43,2 años. El seguimiento promedio posterior al inicio del tratamiento médico o quirúrgico fue de 16 meses. En el grupo de manejo quirúrgico, la tasa de recurrencia fue del 7,2 % y el intervalo de recurrencia fue 29,2 meses. Conclusiones: Los pacientes a quienes se les practicó la técnica de trombectomía más fleboextracción presentaron una menor tasa de retrombosis hemorroidal, menor tasa de dolor y sangrado posoperatorio. La trombectomía hemorroidal con fleboextracción es una técnica bien tolerada en el consultorio, que se puede realizar sin anestesia, a diferencia del estándar de manejo actual con hemorroidectomía externa en elipse, que requiere anestesia local, regional o general, y una sala de procedimientos quirúrgicos que deja un defecto mayor en la piel por el tejido resecado, un mayor tiempo de cicatrización y de dolor posoperatorio.

Abstract Objective: To evaluate the results of thrombectomy combined with vein stripping as an alternative to treat external thrombosed hemorrhoid disease. Materials and methods: This is an observational, quantitative, retrospective, cross-sectional and descriptive study of the patients who underwent thrombectomy combined with vein stripping as an alternative technique to treat thrombosed external hemorrhoid disease at the Coloproctology Service of the Hospital Militar Central from January 1, 2014, to December 31, 2016. Results: It was found that 197 patients consulted due to thrombosed external hemorrhoids. 71% were men. The average age for the conservative treatment group vs. the surgical treatment group was 48.5 vs. 43.2 years, respectively. The average follow-up time after initiation of medical or surgical treatment was 16 months. In the surgical treatment group, the recurrence rate was 7.2% and the recurrence interval was 29.2 months. Conclusions: Patients who underwent thrombectomy combined with vein stripping had a lower recurrence rate of thrombosed hemorrhoids, a lower pain score, and less postoperative bleeding. Hemorrhoid thrombectomy combined with vein stripping is a well-tolerated technique that can be performed at the doctor's office without anesthesia, unlike the current management standard with external elliptical hemorrhoidectomy, which that requires local, regional, or general anesthesia, and a surgical room, leaving a larger skin defect following the resection of the tissue, with longer healing time and greater postoperative pain.

Impact of Ambulatory Surgery for Hemorrhoidal Disease on Clinical Outcomes and Institutional Costs / Impacto da cirurgia ambulatória para patologia hemorroidária nos resultados clínicos e custos

Abstract Objective Transanal hemorrhoidal artery ligation with mucopexy (ligation anopexy [LA]) and open hemorrhoidectomy (OH) can both be performed under local anesthesia. The aim of the present study was to analyze the impact and the cost-effectiveness of performing these techniques in an ambulatory setting of an Italian academic center on the postoperative outcome. Methods A series of 122 consecutive patients with grades II and III hemorrhoidal disease undergoing ambulatory surgical treatment of hemorrhoids in 2015 to 2018 (group A) was comparedwith 122 patients operated at the same institution in the same period (group H) in a hospital setting. The primary outcome was the number of days required to return to work/daily activities. Secondary outcomes included postoperative pain and complications, costeffectiveness, patient satisfaction, and recurrence at 12 months. In group A, all the procedures were performed under local anesthesia with early discharge. In group H, the procedureswere performed under general or loco-regional anesthesia with hospital admission. Results The mean number of days required to return to work/daily activities was 8.4 ± 4.8 days in group A, compared with 12.5 ± 3 days in group H (p<0.001). The visual analog scale (VAS) pain score at 1 week, 2 and 3 weeks, and 1 month after surgery was lower for patients undergoing LA in the ambulatory setting (p<0.01). We observedmore postoperative complications in hospitalized (12.5%) than in ambulatory patients (7.5%) (p<0.001). The total mean direct costs per patient were significantly lower in the ambulatory setting versus the hospital stay group (351.3 versus 1,746 euros). Conclusion Implementing ambulatory surgery for hemorrhoids is feasible, safe, and cost-effective.

Resumo Objetivo A ligação transanal da artéria hemorroidária com mucopexia e a hemorroidectomia aberta (HA) podem ser realizadas em anestesia local. O objetivo do presente estudo foi analisar o impacto no resultado pós-operatório e a relação custo-eficácia da realização destas técnicas em ambiente ambulatorial de um centro acadêmico italiano no desfecho pós-operatório. Métodos Uma série de 122 pacientes consecutivos com patologia hemorroidária de graus II e III submetidos a cirurgia de hemorroidas em regime ambulatório de 2015 a 2018 (grupo A) foi comparada com 122 pacientes operados na mesma instituição no mesmo período (grupo H) por hospitalização. O desfecho primário foi o número de dias necessários para regressar ao trabalho/atividades diárias. Os desfechos secundários incluíram dor e complicações pós-operatórias, custo-eficácia, satisfação do paciente, e recidiva aos 12 meses. No grupo A, todos os procedimentos foram realizados em anestesia local. No grupo H, os procedimentos foram realizados em anestesia geral ou loco-regional. Resultados A espera média para o regresso ao trabalho foi de 8,4 ± 4,8 dias no grupo A em comparação com 12,5 ± 3 dias no grupo H (p<0,001). A pontuação na escala visual analógica (EVA) da dor 1 semana, 2 e 3 semanas, e 1 mês após a cirurgia foi mais baixa para os pacientes submetidos a cirurgia de ligadura com anopexia em ambiente ambulatorial (p<0,01). Observamosmais complicações pós-operatórias empacientes hospitalizados (12,5%) do que em pacientes ambulatórios (7,5%) (p<0,001). Os custos diretosmédios totais por paciente foram mais baixos em ambiente ambulatório do que no grupo de hospitalização (351,3 contra 1.746 euros). Conclusão A implementação da cirurgia ambulatória para hemorroidas é possível, segura e rentável.

A new mixed surgical treatment for grades iii and iv hemorrhoids: modified selective hemorrhoidectomy combined with complete anal epithelial retention / Um novo tratamento cirúrgico para hemorroidas mistas graus iii e iv: hemorroidectomia seletiva modificada combinada com retenção epitelial anal completa

ABSTRACT Background: Varicose veins appear above and below the dentate line in mixed hemorrhoids, which seriously affects anal function and quality of life. Aim: To propose an improvement in tissue-selecting therapy repair of anal pad combined with complete anal canal epithelial retention comparing with Milligan-Morgan surgery. Methods: A prospective randomized controlled study was designed enrolling 200 patients with grade III and IV hemorrhoids. They were divided into control and observation groups. The control received Milligan-Morgan surgery, and the observation the modified tissue-selecting therapy stapler combined with complete anal canal preservation surgery. All patients were followed for six months to evaluate the treatment differences. Results: In final, control group included 82 and observation 87. The average operation time of the control group was significantly lower than that of the observation, while the bleeding volume was significantly lower in control group. The control group VAS score was 3 (1, 4), and observation 4 (2, 5). There was no significant difference in the incidence of urinary retention, bleeding and wound margin edema after surgery at one month postoperatively. Digital incidence of anal stenosis in the observation group was significantly lower than in control; the same occurred with residual anal margins. The postoperative anal canal diameter was significantly larger than the control group. Wexner anal incontinence score showed that no anal incontinence occurred in both groups, and the control group scored was significantly higher than observation. In final six months follow-up, the observation group did not experience any relapse and four cases were found among controls. The treatment satisfaction of the observation group was better. Conclusions: In grades III and IV hemorrhoids, modified tissue-selecting therapy combined with complete anal canal preservation had better prognosis and treatment satisfaction than Milligan-Morgan procedure, and it is a new surgical method for patients with advanced mixed hemorrhoids.

RESUMO Racional: Veias varicosas aparecem acima e abaixo da linha dentada nas hemorroidas mistas, afetando seriamente a função anal e a qualidade de vida. Objetivo: Propor melhoria na terapia de seleção de tecido de reparo do coxim anal combinado com retenção completa epitelial do canal anal em comparação com a operação de Milligan-Morgan. Métodos: Estudo prospectivo randomizado controlado foi desenhado envolvendo 200 pacientes com hemorroidas graus III e IV. Eles foram divididos em grupos de controle e observação. O controle recebeu operação de Milligan-Morgan, e o de observação procedimento de seleção de tecido modificado combinado com operação completa de preservação do canal anal. Todos os pacientes foram acompanhados por seis meses para avaliar as diferenças de tratamento. Resultados: No final, o grupo controle incluiu 82 e o de observação 87. O tempo médio de operação do grupo controle foi significativamente menor do que o de observação, enquanto o volume de sangramento foi significativamente menor no grupo controle. O escore VAS do grupo controle foi 3 (1, 4) e no de observação 4 (2, 5). Não houve diferença significativa na incidência de retenção urinária, sangramento e edema da margem da ferida no pós-operatório de um mês. A incidência de estenose anal digital no grupo observação foi significativamente menor do que no controle; o mesmo ocorreu com as margens anais residuais. O diâmetro do canal anal pós-operatório foi significativamente maior nele do que o grupo controle. A pontuação de incontinência anal de Wexner mostrou que nenhuma incontinência ocorreu em ambos os grupos, e a pontuação do grupo de controle foi significativamente maior do que no de observação. Nos últimos seis meses de acompanhamento, o grupo observação não teve nenhuma recaída e quatro casos foram encontrados entre os controles. A satisfação com o tratamento do grupo observação foi maior. Conclusões: Nas hemorroidas graus III e IV, o tratamento de seleção de tecido modificado combinado com a preservação completa do canal anal teve melhor prognóstico e satisfação do que com o procedimento de Milligan-Morgan, e é um novo método cirúrgico para pacientes com hemorroidas mistas avançadas.

A new approach for hemorrhoid disease: selective dearterialization and mucopexy without doppler guidance / Uma nova opção para o tratamento da doença hemorroidária: desarterialização e mucopexia seletiva sem o ultrassom doppler

ABSTRACT Background: Transanal hemorrhoidal dearterialization (THD) is safe and effective minimally invasive treatment for hemorrhoidal disease, but reports regarding recurrence and postoperative complications (pain and tenesmus) vary significantly. Aim: To evaluate if selective dearterialization and mucopexy at the symptomatic hemorrhoid only, without Doppler guidance, achieves adequate control of the prolapse and bleeding and if postoperative morbidity is reduced with this technique. Methods: Twenty consecutive patients with grade II and III hemorrhoids were treated with this new approach and were evaluated for postoperative complications and recurrence. Results: Control of prolapse and bleeding was achieved in all patients (n=20). Postoperative complications were tenesmus (n=2), external hemorrhoidal thrombosis (n=2) and urinary retention (n=2). After a mean follow-up of 13 months no recurrences were diagnosed. Conclusion: Selective dearterialization and mucopexy is safe and achieves adequate control of prolapse and bleeding and, by minimizing sutures in the anal canal, postoperative morbidity is diminished. Doppler probe is unnecessary for this procedure, which makes it also more interesting from an economic perspective.

RESUMO Racional: O tratamento da doença hemorroidária pela técnica de THD (Transanal Hemorrhoidal Dearterialization) é minimamente invasivo e tem se mostrado seguro e eficiente. No entanto, dados sobre a recorrência e complicações (dor e tenesmo) no pós-operatório são muito variáveis. Objetivo: Avaliar se a desarterialização e mucopexia seletiva, sem o uso de Doppler, é suficiente para o controle de sintomas e se a morbidade pós-operatória é menor com esta técnica. Métodos: Vinte pacientes foram tratados com essa técnica e avaliados sobre controle de sintomas, morbidade pós-operatória e recorrência. Resultados: Controle do prolapso e sangramento foi observado em todos pacientes (n=20). Complicações pós-operatórias foram: tenesmo (n=2), trombose hemorroidária externa (n=2), retenção urinária (n=2). Após um seguimento médio de 13 meses, nenhuma recorrência foi detectada. Conclusões: O procedimento de desarterialização e mucopexias seletivas é seguro e eficiente em termos de controle do prolapso e sangramento. Esta técnica resulta em menor morbidade cirúrgica, uma vez que diminui o número de suturas no canal anal, resultando em menos dor e tenesmo pós-operatório. Para este procedimento o uso de ultrassom Doppler é desnecessário, o que diminui custos e o torna mais atrativo do ponto de vista econômico.

"PNR-Bleed" classification and Hemorrhoid Severity Score-a novel attempt at classifying the hemorrhoids / Classificação "PNR-Bleed" e escore de gravidade das hemorróidas - uma nova tentativa de classificação de hemorróidas

ABSTRACT Hemorrhoids are the most common anorectal disorders with a prevalence of 39% in general population. Hemorrhoids are generally classified on the basis of their location and degree of prolapse. Goligher's classification does not describe the number of hemorrhoidal columns involved and does not give much consideration to the amount of blood loss. To describe the hemorrhoidal disease more vividly, we devised the "PNR-Bleed" (or PNR-Booking) classification system. We tried to classify the hemorrhoids based on the four main characteristics of the hemorrhoidal disease i.e. the degree of hemorrhoidal Prolapse (P), Number (N) of the primary hemorrhoidal columns involved, Relation (R) of the hemorrhoidal tissue to dentate line and the amount of Bleeding (B) from it. All the four components in this classification system are graded into five grades ranging from 1 to 5. The peculiarity of this new classification system is that it allows more detailed documentation of the hemorrhoids in a particular patient and conveys more explicit meaning and information about the hemorrhoids for future references. Based on this 'PNR-Bleed' classification, we are introducing another concept of scoring the severity of hemorrhoids and referred it as the Hemorrhoid Severity Score (HSS). Hemorrhoid Severity Score (HSS) is the total score obtained by the sum of the numerical grades of all four characteristics of hemorrhoids in "PNR-Bleed" classification. This new "PNR-Bleed" system of classifying the hemorrhoids and calculation of HSS seems to be more comprehensive, detailed, more objective and easily reproducible.

RESUMO As hemorróidas são os distúrbios anorretais mais comuns, com uma prevalência de 39% na população em geral. As hemorróidas são geralmente classificadas com base em sua localização e grau de prolapso. A classificação de Goligher não descreve o número de colunas hemorroidais envolvidas e não dá muita importância à quantidade da perda de sangue. Para descrever a doença hemorroidária de maneira mais precisa, criamos o sistema de classificação "PNR-Bleed" (ou PNR-Booking). Tentamos classificar as hemorróidas com base nas quatro principais características da doença hemorroidária, isto é, o grau de prolapso da hemorroida (P), número (N) das colunas hemorroidais primárias envolvidas, a relação (R) do tecido hemorroidário para a linha denteada e a quantidade de sangramento (B) originando-se dele. Todos os quatro componentes deste sistema de classificação são classificados em cinco graus, variando de 1 a 5. A peculiaridade desse novo sistema de classificação é que ele permite uma documentação mais detalhada das hemorróidas em um paciente em particular e transmite o significado e informações mais explícitos sobre as hemorróidas. para referências futuras. Com base nessa classificação "PNR-Bleed", estamos introduzindo outro conceito para o escore da gravidade das hemorróidas e denominado HSS, de "Hemorrhoid Severity Score". O escore de gravidade da hemorroida (HSS) é o escore total obtido pela soma dos graus numéricos de todas as quatro características das hemorróidas na classificação "PNR-Bleed". Esse novo sistema "PNR-Bleed" de classificação de hemorróidas e cálculo do HSS parece ser mais abrangente, detalhado, mais objetivo e facilmente reproduzível.

A new theory on the cause of anal fissure - impaction theory / Uma nova teoria sobre a causa da fissura anal - teoria da impactação

ABSTRACT The internal hemorrhoid, rectal tumor, hypertrophic anal papilla, and secret fecal mass are regarded as the blocks embedded in the rectum. The above blocks hinder defecation, which will inevitably lead to excessive opening of the anal caliber. Once the limit is exceeded, the skin of the anal canal will tear and form anal fissure. Based on the study of historical evolution, hypothesis reasoning, clinical verification and comparison with other theories, a new concept of anal fissure etiology-impaction theory is proposed. The so-called impaction theory refers to the impaction (various primary lesions) in anorectum, which hinders defecation. When defecating, the anal canal expands beyond the limit, and the whole layer of anal canal skin splits, that is to say, anal fissure is formed.

RESUMO A hemorroida interna, o tumor retal, a papila anal hipertrófica e a massa fecal secreta são considerados os blocos incrustados no reto. Os bloqueios acima impedem a defecação, o que inevitavelmente levará a uma abertura excessiva do calibre anal. Uma vez que o limite é excedido, a pele do canal anal rasga e forma uma fissura anal. Com base no estudo da evolução histórica, raciocínio de hipóteses, verificação clínica e comparação com outras teorias, um novo conceito de etiologia da fissura anal - a teoria da impactação - é proposto. A chamada teoria da impactação refere-se à impactação (várias lesões primárias) no anorreto, o que dificulta a defecação. Na defecação, o canal anal se expande além do limite e toda a camada da pele do canal anal rasga, ou seja, forma-se a fissura anal.

The role of platelet parameters in thrombosed hemorrhoids / O papel dos parâmetros plaquetários nas hemorróidas trombosadas

ABSTRACT Objectives: The most common disease of anus is hemorrhoids. The definition of external hemorrhoids suggests the acute phase, often characterized by thrombosis or edema. External thrombosed hemorrhoid is a specific complication. In this study, we aimed to investigate the effects of different platelet parameters in the presence of internal or external thrombosed hemorrhoids. Methods: Patients examined were divided into two groups: Group 1: Thrombosed hemorrhoids group (THG), Group 2: Hemorrhoidectomy group (HG). Demographic and clinical data were identified. In terms of laboratory findings, preoperative hemoglobin, hematocrit and all platelet parameters were recorded. Main results: Fifty-two patients in THG, and 75 patients in HG were included in the study. In female sex and young age group, the risk of developing thrombosed hemorrhoids was statistically significant (p= 0.029, p= 0.039, respectively). When the platelet parameters were evaluated; while PDW was higher in THG (p= 0.008), any significant difference could not found in all other values (p> 0.05). Thrombosed hemorrhoids were mostly (59.25%) found to be located in the left laterodorsal part of anus. Conclusion: Internal hemorrhoids are frequently seen in the ages of 45-65 with similar rates in both sexes, while external thrombosed hemorrhoids occur at a younger age (<45) and more often in women. Comparing in terms of platelet indexes, PDW value was found to be significantly higher in THG. In young people, thrombosed hemorrhoids may develop more frequently, as the connective tissue that forms the anal pads is not loose enough to form an internal hemorrhoid, as more seen in older patients.

RESUMO Objetivos: A doença anal mais comum são as hemorróidas. A definição de hemorróidas externas sugere a fase aguda, muitas vezes caracterizada por trombose ou edema. A hemorroida externa trombosada é uma complicação específica. Neste estudo, objetivamos investigar os efeitos de diferentes parâmetros plaquetários na presença de hemorróidas trombosadas internas ou externas. Métodos: Os pacientes examinados foram divididos em dois grupos: Grupo 1, Grupo de Hemorróidas Trombosadas (GHT); Grupo 2, Grupo de hemorroidectomia (GH). Os dados demográficos e clínicos foram identificados. Em termos de achados laboratoriais, a hemoglobina pré-operatória, o hematócrito e todos os parâmetros plaquetários foram registrados. Resultados principais: Cinquenta e dois pacientes em GHT e 75 pacientes em GH foram incluídos no estudo. No sexo feminino e na faixa etária jovem, o risco de desenvolver hemorróidas trombosadas foi estatisticamente significativo (p = 0,029, p = 0,039, respectivamente). Os parâmetros plaquetários avaliados mostraram que, enquanto a Amplitude de Distribuição de Plaquetas (PDW, do inglês platelet distribution width) foi maior no GHT (p = 0,008), nenhuma diferença significativa foi encontrada para todos os outros valores (p > 0,05). A maioria das hemorróidas trombosadas (59,25%) localizava-se na região lateral-dorsal esquerda do ânus. Conclusão: As hemorróidas internas são frequentemente vistas nas idades de 45 a 65 anos com taxas semelhantes em ambos os sexos, enquanto as hemorróidas externas trombosadas ocorrem em uma idade mais jovem (<45) e mais frequentemente em mulheres. Comparando em termos de índices de plaquetas, foi observado que o valor de PDW foi significativamente maior no GHT. Em pessoas jovens, as hemorróidas trombosadas podem se desenvolver com mais frequência, pois o tecido conjuntivo que forma as almofadas anais não é flácido o suficiente para formar uma hemorroida interna, como ocorre com mais frequência em pacientes mais velhos.

The effect of nitric oxide, endothelial nitric oxide synthetase, and asymmetric dimethylarginine in hemorrhoidal disease

SUMMARY AIM The aim of this study was to examine the roles of nitric oxide (NOx), endothelial nitric oxide synthetase (eNOS), and asymmetric dimethylarginine (ADMA), which is the major endogenous inhibitor of nitric oxide synthases (NOS), in the pathophysiology of hemorrhoidal disease. METHODS This study included 54 patients with grades 3 and 4 internal hemorrhoidal disease and 54 patients without the disease who attended the General Surgery Clinic. NOx, eNOS, and ADMA levels were measured with the Enzyme-Linked ImmunoSorbent Assay (ELISA) method. RESULTS The patients had higher NO and eNOS levels and lower ADMA levels than the control subjects (p<0.001). A significant highly positive correlation was found between NO and eNOS (p<0.001). Nevertheless, there was a highly negative correlation between ADMA and NO-eNOS(p<0.001, p<0.001). CONCLUSION This preliminary study reveals that higher NOx and eNOS activities and lower ADMA levels in the rectal mucosa are observed in patients with hemorrhoidal disease than in those with normal rectal tissue. The imbalance between endothelium-derived relaxing factors, such as NO and endogenous competitive inhibitor of NOS, ADMA, may cause hemorrhoidal disease. Our study proposes that hemorrhoids display apparent vascular dilatation and present with bleeding or swelling. ADMA is an effective NOS inhibitor and may be a promising therapeutic option for hemorrhoidal disease.

RESUMO OBJETIVO O objetivo deste estudo foi examinar os papéis do óxido nítrico (NOx), do óxido nítrico sintetase endotelial (eNOS) e da dimetilarginina assimétrica (ADMA), que é o principal inibidor endógeno das óxido nítrico sintase (NOS) na fisiopatologia da doença hemorróida. MÉTODOS Este estudo incluiu 54 pacientes com doença hemorróida interna de grau 3 e 4 e 54 pacientes sem a doença que se inscreveram na Clínica Geral de Cirurgia. Os níveis de NOx, eNOS e ADMA foram medidos com o método de Ensaio Imuno absorvente ligado a enzima (ELISA). RESULTADOS Os pacientes têm níveis mais altos de NO e eNOS e níveis mais baixos de ADMA do que os indivíduos controle (p <0,001). Uma correlação altamente positiva significativa foi encontrada entre o NO-eNOS (p <0,001). No entanto, houve uma correlação negativa muito séria entre ADMA e NO-eNOS (p <0,001, p <0,001). CONCLUSÃO Este estudo preliminar revela que os pacientes com doença hemorróida têm atividades mais altas de NOx e eNOS e níveis mais baixos de ADMA na mucosa retal do que os pacientes com tecido retal normal. Desequilíbrio entre o fator relaxante derivado do endotélio, como; O NO e o inibidor competitivo endógeno da NOS, ADMA, podem causar doenças hemorróidas. Nosso estudo propõe que as hemorróidas exibam aparente dilatação vascular e apresentam sangramento ou inchaço, a ADMA é um inibidor eficaz da NOS e pode ser uma opção terapêutica promissora para a doença hemorróida.
