Traumatismo anorrectal contuso. Reporte de un caso y revisión bibliográfica / Blunt anorectal trauma. Case reportand literature review

Introducción: El traumatismo anorrectal es una causa poco frecuente de consulta al servicio de emergencias, con una incidencia del 1 al 3%. A menudo está asociado a lesiones potencialmente mortales, por esta razón, es fundamental conocer los principios de diagnóstico y tratamiento, así como los protocolos de atención inicial de los pacientes politraumatizados. Método: Reportamos el caso de un paciente masculino de 47 años con trauma anorrectal contuso con compromiso del esfínter anal interno y externo, tratado con reparación primaria del complejo esfinteriano con técnica de overlapping, rafia de la mucosa, submucosa y muscular del recto. A los 12 meses presenta buena evolución sin incontinencia anal. Conclusión: El tratamiento del trauma rectal, basado en el dogma de las 4 D (desbridamiento, derivación fecal, drenaje presacro, lavado distal) fue exitoso. La técnica de overlapping para la lesión esfinteriana fue simple y efectiva para la reconstrucción anatómica y funcional. (AU)

Introduction: Anorectal trauma is a rare cause of consultation to the Emergency Department, with an incidence of 1 to 3%. It is often associated with life-threatening injuries, so it is essential to know the principles of diagnosis and treatment, as well as the initial care protocols for the polytrau-matized patient. Methods: We present the case of a 47-year-old man with a blunt anorectal trauma involving the internal and external anal sphincter, treated with primary overlapping repair of the sphincter complex and suturing of the rectal wall. At 12 months the patient presents good outcome, without anal incontinence. Conclusion: The treatment of rectal trauma, based on the 4 D ́s dogma (debridement, fecal diversion, presacral drainage, distal rectal washout lavage) was successful. Repair of the overlapping sphincter injury was simple and effective for anatomical and functional reconstruction. (AU)

Presentaciones de la sífilis anorrectal: la gran simuladora / Anorectal syphilis presentations: the great pretender

Antecedentes: La sífilis es una infección sexualmente transmisible sistémica crónica que afecta a docenas de millones de personas al año. A nivel anorrectal, su manifestación polimórfica obliga al diagnóstico diferencial con enfermedades anorrectales benignas y malignas. Objetivo: Describir las diferentes presentaciones de la sífilis anorrectal a propósito de 5 casos clínicos. Método: Estudio observacional, retrospectivo, descriptivo. Resultados: La mayoría de los pacientes fueron VIH positivos en edad sexual activa. Las manifestaciones registradas, al igual que las reportadas en la bibliografía fueron las fisuras, úlceras perianales y pseudotumores. Conclusiones: La sífilis es considerada "la gran simuladora". En la localización anorrectal se requiere una alta sospecha diagnóstica para diferenciarla de presentaciones similares de otras enfermedades anales benignas, la enfermedad inflamatoria intestinal y el cáncer anorrectal, con el fin de evitar el consiguiente riesgo de sobretratamiento. (AU)

Background: Syphilis is a chronic systemic sexually transmitted infection that affects tens of millions of people annually. At the anorectal level, its polymorphic manifestation requires differential diagnosis with benign and malignant anorectal diseases. Objective: To review the presentation of anorectal syphilis from 5 clinical cases. Methods: Observational, retrospective, descriptive study. Results: Most of the patients were HIV positive in sexually active age. The manifestations recorded and reported in the literature were fissures, perianal ulcers, and pseudotumors. Conclusions: Syphilis is considered "the great pretender". In anorectal syphilis, a high diagnostic suspicion is needed to differentiate it from similar presentations due to other anal conditions, inflammatory bowel disease, and anorectal cancer, to avoid the consequent risk of overtreatment.

Dyssynergic Defecation Concerning Proctalgia Fugax: An Observational Study

Introduction: There is no clarity about manometric findings in patients with proctalgia fugax; evidence shows different results. This study aims to evaluate dyssynergic defecation through anorectal manometry in Colombian patients in two gastroenterology centers in Bogotá, Colombia. Materials and methods: A cross-sectional descriptive observational study in adult patients with proctalgia fugax undergoing anorectal manometry and treated in two gastroenterology centers in Bogotá between 2018 and 2020. Results: 316 patients were included, predominantly women (65%), with a median age of 45.2 (range: 18-78; standard deviation [SD]: 28.3). Four percent of patients had hypertonicity, 50% were normotonic, and 46% were hypotonic. Regarding manometric parameters, 50% had normal pressure, and 46% had anal sphincter hypotonia; 76% had a normal voluntary contraction test. Dyssynergic defecation was documented in 5% of patients, and the most frequent was type I, followed by type III. A rectoanal inhibitory reflex was identified in all patients, 42% with altered sensory threshold and 70% with abnormal balloon expulsion. There was an agreement between the results of the anorectal manometry and the subjective report of the digital rectal exam by the head nurse who performed the procedure. Conclusions: The data obtained in the present study suggest that proctalgia is not related to the elevated and sustained basal contracture of the sphincter but neither to the alteration in voluntary contraction since most patients have typical values.

Introducción: Actualmente, no hay claridad acerca de los hallazgos manométricos en pacientes con proctalgia fugaz, y la evidencia muestra diferentes resultados. Se plantea como objetivo en el presente estudio evaluar la presencia de disinergia defecatoria con manometría anorrectal en pacientes colombianos en dos centros de gastroenterología en Bogotá, Colombia. Metodología: Estudio observacional descriptivo de corte transversal en pacientes adultos sometidos a manometría anorrectal con proctalgia fugaz y atendidos en dos centros de gastroenterología de la ciudad de Bogotá entre el 2018 y el 2020. Resultados: Se incluyó a 316 pacientes, predominantemente mujeres (65%), con mediana de edad 45,2 (rango: 18-78; desviación estándar [DE]: 28,3). El 4% de los pacientes presentaban hipertonicidad, el 50% eran normotónicos y el 46%, hipotónicos. En cuanto a parámetros manométricos, el 50% tenía presión normal y el 46%, hipotonía de esfínter anal. El 76% tuvo una prueba de contracción voluntaria normal. En 5% pacientes se documentó disinergia defecatoria, y la más frecuente fue el tipo I, seguido del tipo III. En todos los pacientes se identificó reflejo recto anal inhibitorio, 42% con alteración en umbral sensitivo y 70% con expulsión de balón anormal, y hubo concordancia entre los resultados de la manometría anorrectal y el reporte subjetivo del tacto rectal de la jefe de enfermería que realizó el procedimiento. Conclusiones: Los datos obtenidos en el presente estudio sugieren que la proctalgia no está relacionada con la contractura basal elevada y sostenida del esfínter, pero tampoco con la alteración en la contracción voluntaria, ya que la mayoría de los pacientes presentan valores normales.

Postoperative analgesic efficacy of nefopam after anorectal surgery: a retrospective observational study

Objective: To examine the effectiveness of nefopam on postoperative pain control after anorectal surgeries. Methods: We retrospectively reviewed the electronic medical records of patients who underwent anorectal surgeries from January 2019 to March 2022 at two medical centers. The data were divided into nefopam and conventional groups. The primary outcome was the number of patients who requested additional opioids in the 24-h postoperative period. The secondary outcomes were numeric rating pain scores (NRPS) within a 24-h postoperative period and analgesic drugs-related side effects. Results: Eighty-seven patients in the conventional group and 60 in the nefopam group were recruited. The nefopam group reported less additional opioid consumption than the conventional group in all dimensions of analysis, including overall, adjusted to anesthetic techniques and types of surgery. However, these did not reach statistical significance (P = 0.093). Only patients in the nefopam group who underwent hemorrhoidectomy under TIVA or spinal anesthesia significantly required fewer additional opioids (P = 0.016, 60% mean difference). Similarly, the 24-h postoperative morphine consumption was lower in the nefopam group (mean difference = -3.4, 95%CI: 0.72,6.08). Furthermore, significantly lower NRPS were reported in the nefopam group during the 12-18 h postoperative period (P = 0.009). On the other hand, analgesic drugs related side effects were similar in both groups. Conclusions: The administration of nefopam after major anorectal surgery is beneficially evident in reducing postoperative opioid requirements. (AU)

Síndrome de Currarino incompleto. Presentación de un caso

El síndrome de Currarino es una enfermedad hereditaria y de baja incidencia, compuesta por una tríada: estenosis anal, malformación sacro coccígea y masa presacra. Puede cursar desapercibido hasta la adultez y generar subdiagnósticos. Se describe un paciente de 75 años, masculino, piel negra, de procedencia urbana y con antecedentes de hipertensión arterial, quien acudió al hospital por presentar hematuria, dolor en fosa lumbar izquierda y estreñimiento. Se realizaron estudios imagenológicos, como ultrasonido, tomografía de abdomen y resonancia magnética lumbosacra, los cuales condujeron al diagnóstico de tumor renal, síndrome de Currarino incompleto (dado por dos elementos de la triada: malformación sacro coccígea y masa presacra) asociado a otra enfermedad malformativa raquimedular, médula anclada. Son pocos los casos reportados en el mundo (casi 300), por lo que se considera una entidad rara, pero de fácil diagnóstico debido al advenimiento de las nuevas tecnologías en el campo de la imagenología.

Currarino syndrome is a hereditary disease with a low incidence, composed of a triad: anal stenosis, sacrococcygeal malformation and presacral mass. It can go unnoticed until adulthood and generate subdiagnoses. A 75-years-old male, black-skinned, urban origin patient with a history of arterial hypertension is described, who attended the hospital presenting hematuria, pain in the left lumbar fossa, and constipation. Radiological studies such as ultrasound, abdominal tomography and lumbosacral magnetic resonance were performed, which led to the diagnosis of a renal tumor, incomplete Currarino syndrome (given by two elements of the triad: sacrococcygeal malformation and presacral mass) associated with another spinal cord malformation disease, tethered cord. There are few cases reported in the world (almost 300), so it is considered a rare entity, but easy to diagnose due to new imaging technologies.

Predictors of long-term healing for endorectal advancement flap for anorectal fistulas

Introduction: Anorectal fistulas are some of the commonest surgical proctologic disorders treated by surgeons. Despite the recent introduction of various sphincter preserving techniques, the search for the optimal operation continues. The purpose of this study was to determine the predictors of long-term healing for the endorectal advancement flap. Methods: A retrospective review of a single surgeon experience with the endorectal advancement flap for anorectal fistulas over an 18-year period. The impact of various patient and fistula related factors were analyzed for their impact on the primary endpoint of long-term fistula healing. Results: 87 patients underwent endorectal advancement flap (Male/Female 42.5/57.5%). Median age was 41 years. Sixty-nine patients (79.3%) had anal fistula while 18 patients had rectal fistula (20.7%). An anterior based fistula was noted in 45 patients (51.7%). The most common etiology was cryptoglandular disease (87.4%). The median operative time was 75minutes (range 36-250). Postoperative septic complications were noted in 4 patients (4.6%). Fistula healing was documented in 80 patients (93%). During a median follow-up of 4 months (range 1-38, 1 patient lost to follow-up), recurrence was noted in 8 patients (9.3%), yielding an overall long-term success rate of 83.7%. The long-term healing rate was higher in patients with fistulas from cryptoglandular etiology (86.6%) compared to fistulas from other etiologies (63.6%) [p = 0.027]. Conclusions: The endorectal advancement is associated with a high healing rate, a low postoperative septic complication rate, and infrequent risk for recurrence. Long-term healing without recurrence is achieved more frequently in patients with cryptoglandular etiology of the fistula compared to patients with non-cryptoglandular etiology. (AU)

Eficácia da reabilitação perineal combinada com biofeedback e diatermia por radiofrequência (RDF) em síndromes de dor funcional anorretal associadas à contração paradoxal dos músculos elevadores do ânus. Um estudo prospectivo / Effectiveness of perineal pelvis rehabilitation combined with biofeedback and radiofrequency diathermy (rdf) in anorectal functional pain syndromes associated with paradoxical contraction of the levator ani muscles. a prospective study

ABSTRACT Background: Anorectal functional pain syndrome, also called chronic proctalgia, represents a neglected clinical entity and often confused with other syndromes such as vulvodynia or acute proctalgia. It is a very often disabling disease with a consequent significant negative impact on the patient's quality of life. Chronic proctalgia, in many patients, is secondary to the paradoxical contraction of the pelvic floor and associated with a dissynergy between the thorax-abdomen and the pelvic floor. To improve symptoms in functional anorectal pain syndromes, various rehabilitation techniques are used with the aim of promoting relaxation of the pelvic floor; however, to improve defecatory dynamics in patients with levator ani syndrome, only biofeedback has shown efficacy in a randomized study. The aim of this work is to evaluate whether a rehabilitation protocol with manometric biofeedback and radiofrequency diathermy (mt100 Fremslife emotion Tecar) reduces pain and paradoxical contraction of the levator ani and improves the quality of life in patients with anorectal pain syndromes. functional. Methods: This was a prospective study on 30 patients (20 women and 10 men) with anorectal functional pain syndrome and paradoxical contraction of the pelvic floor enrolled at the UOC of General, Minimally Invasive, Oncological and Obesity Surgery of the AOU "Luigi Vanvitelli" of Naples, Italy, from September 2021 to May 2022. All patients were evaluated with a coloproctological specialist visit followed by anorectal manometry and evaluation of altered clinical physiatric parameters (Brusciano Score). The protocol consisted of 10 rehabilitation sessions of the pelvic floor once a week and lasting approximately 45 minutes. During the sessions the patients were subjected to diathermy / radiofrequency treatment (10 minutes) with a static resistive electrode on the diaphragm, during which they were required to breathe diaphragmatically and to become aware of the perineal muscles, under the supervision of a physiotherapist; followed by application of diathermy with static capacitive (5 minutes) and resistive (10 minutes) electrode at the lumbar level. This was followed by the use of manometric biofeedback (15 minutes of tonic / phasic exercises) in order to instruct the patient on the reflex mechanism to obtain a voluntary relaxation of the external anal sphincter. The variables evaluated were Pain (VAS 0-10) and the questionnaire on the impact of colorectal and anal pathologies on the quality of life (CRAIQ-7) at the beginning, after 3 months and at the end of the treatment. Results: After 10 weeks, the rehabilitation treatment combined with diathermy and manometric biofeedback proved effective in the short term with a reduction in the scores of the Vas scale and CRAIQ-7 questionnaire and an increase in the percentage of release of the anal muscles on anorectal manometry. Conclusion: The use of radiofrequency diathermy with a system of static electrodes associated with biofeedback represents a valid rehabilitation option for those patients suffering from anorectal functional pain syndrome because it reduces pain and paradoxical contraction of the levator ani and improves quality of life of the patient.

RESUMO Contexto: A síndrome de dor funcional anorretal, também conhecida como proctalgia crônica, representa uma entidade clínica negligenciada e frequentemente confundida com outras síndromes, como vulvodinia ou proctalgia aguda. Trata-se de uma doença frequentemente incapacitante, com um consequente impacto negativo significativo na qualidade de vida do paciente. A proctalgia crônica, em muitos pacientes, é secundária à contração paradoxal do assoalho pélvico e está associada a uma dissinergia entre o tórax-abdômen e o assoalho pélvico. Para melhorar os sintomas em síndromes de dor anorretal funcional, são utilizadas diversas técnicas de reabilitação com o objetivo de promover o relaxamento do assoalho pélvico. No entanto, para melhorar a dinâmica de evacuação em pacientes com síndrome do elevador do ânus, apenas o biofeedback demonstrou eficácia em um estudo randomizado. Objetivo: O objetivo deste trabalho é avaliar se um protocolo de reabilitação com biofeedback manométrico e diatermia por radiofrequência (mt100 Fremslife emotion Tecar) reduz a dor e a contração paradoxal do elevador do ânus e melhora a qualidade de vida em pacientes com síndromes de dor anorretal funcional. Métodos: Realizado estudo prospectivo com 30 pacientes (20 mulheres e 10 homens) com síndrome de dor anorretal funcional e contração paradoxal do assoalho pélvico inscritos na UOC de Cirurgia Geral, Minimamente Invasiva, Oncológica e de Obesidade da AOU "Luigi Vanvitelli" de Nápoles, Itália, de setembro de 2021 a maio de 2022. Todos os pacientes foram avaliados com uma consulta especializada em coloproctologia, seguida de manometria anorretal e avaliação dos parâmetros fisiátricos clínicos alterados (Escore de Brusciano). O protocolo consistiu em 10 sessões de reabilitação do assoalho pélvico, uma vez por semana, com duração aproximada de 45 minutos. Durante as sessões, os pacientes foram submetidos a tratamento de diatermia / radiofrequência (10 minutos) com um eletrodo resistivo estático no diafragma, durante o qual foram solicitados a respirar através do diafragma e a tomar consciência dos músculos perineais, sob a supervisão de um fisioterapeuta; seguido pela aplicação de diatermia com eletrodo capacitivo estático (5 minutos) e resistivo (10 minutos) no nível lombar. Isso foi seguido pelo uso de biofeedback manométrico (15 minutos de exercícios tônicos /fásicos) com o objetivo de instruir o paciente sobre o mecanismo reflexo para obter um relaxamento voluntário do esfíncter anal externo. As variáveis avaliadas foram Dor (EVA 0-10) e o questionário sobre o impacto das patologias colorretais e anais na qualidade de vida (CRAIQ-7) no início, após 3 meses e no final do tratamento. Resultados: Após 10 semanas, o tratamento de reabilitação combinado com diatermia e biofeedback manométrico mostrou-se eficaz a curto prazo, com uma redução nos escores da escala VAS e do questionário CRAIQ-7, e um aumento na porcentagem de relaxamento dos músculos anais na manometria anorretal. Conclusão: O uso de diatermia por radiofrequência com um sistema de eletrodos estáticos associado ao biofeedback representa uma opção de reabilitação válida para pacientes que sofrem com a síndrome de dor anorretal funcional, pois reduz a dor e a contração paradoxal do elevador do ânus, melhorando a qualidade de vida do paciente.

Clinicopathological features and prognosis of anorectal melanoma: A report of 68 cases / 北京大学学报(医学版)

OBJECTIVE@#To investigate the clinicopathological characteristics of anorectal mucosal melanoma (ARMM), and to evaluate the prognostic factors.@*METHODS@#A total of 68 primary ARMM surgical specimens from 2010 to 2018 were retrospectively studied. Slides were reviewed to evaluate pathological features. Slingluff staging method was used for staging.@*RESULTS@#(1) Clinical features: The median age at diagnosis in this group was 61.5 years, with a male-to-female ratio 1 ∶1.62. The most common complaint was blooding (49 cases). For anatomic site, anorectum was the prevalent (66.2%), followed by rectum (20.6%). At the time of diagnosis, 28 cases were stage Ⅰ (localized stage, 41.2%), 25 cases were stage Ⅱ (regional lymph node metastasis, 36.8%), and 15 cases were stage Ⅲ (distant metastasis, 22.1%). Five patients underwent wide local excision, the rest abdominoperineal resection, and 48 patients received adjuvant therapy after surgery. (2) Pathological features: Grossly 88.2% of the tumors were exophytic polypoid masses, with the median tumor size 3.5 cm and the median tumor thickness 1.25 cm. Depth of invasion below lamina muscularis mucosae ranged from 0-5.00 cm (median 1.00 cm). The deepest site of tumor invasion reached muscular layer in 27 cases, and perirectal tissue in 16 cases. Melanin pigmentation was absent or not obvious in 67.6% of the cases. The predominant cytology was epithelioid (45 cases, 66.2%). The rate for ulceration, necrosis, lymphovascular invasion, and perineural invasion was 89.7%, 35.3%, 55.9%, and 30.9%, respectively. The median mitotic count was 18/mm2. The positive rate of S100, HMB-45 and Melan-A were 92.0%, 92.6% and 98.0%, respectively. The median of Ki-67 was 50%. The incidences of mutations within CKIT, BRAF and NRAS genes were 17.0% (9 cases), 3.8% (2 cases) and 9.4% (5 cases), respectively. (3) Prognosis: Survival data were available in 66 patients, with a median follow-up of 17 months and a median survival time of 17.4 months. The 1-year, 2-year and 5-year overall survival rate was 76.8%, 36.8% and 17.2%, respectively. The rate of lymphatic metastasis at diagnosis was 56.3%. Forty-nine patients (84.5%) suffered from distant metastasis, and the most frequent metastatic site was liver. Univariate analysis revealed that tumor size (>3.5 cm), depth of invasion below lamina muscularis mucosae (>1.0 cm), necrosis, lymphovascular invasion, BRAF gene mutation, lack of adjuvant therapy after surgery, deep site of tumor invasion, and high stage at diagnosis were all poor prognostic factors for overall survival. Multivariate model showed that lymphovascular invasion and BRAF gene mutation were independent risk factors for lower overall survival, and high stage at diagnosis showed borderline negative correlation with overall survival.@*CONCLUSION@#The overall prognosis of ARMM is poor, and lymphovascular invasion and BRAF gene mutation are independent factors of poor prognosis. Slingluff staging suggests prognosis effectively, and detailed assessment of pathological features, clear staging and genetic testing should be carried out when possible. Depth of invasion below lamina muscularis mucosae of the tumor might be a better prognostic indicator than tumor thickness.

Influences of Dixon anus preserving surgery on curative effect, anorectal function and stress response in patients with low rectal cancer / 中国医师进修杂志

Objective:To investigate the influences of Dixon anus preserving surgery on the curative effect, anorectal function and stress response of patients with low rectal cancer.Methods:A total of 150 patients with low rectal cancer admitted to Zhangjiakou Fifth Hospital from May 2016 to March 2019 were retrospective analysis as the study subjects. According to the different surgical methods, the patients were divided into the study group (75 cases) and the control group (75 cases). The patients in the study group received Dixon operation, and the patients in the control group received Miles operation. The general condition of operation, postoperative urination function, stress response [C reactive protein (CRP), interleukin-6 (IL-6), cortisol (Cor) and adrenocorticotropic hormone (ACTH)], anorectal function [anal resting pressure (ARP), maximal squeeze pressure (MSP), anal longest contraction time (ALCT)], quality of life (PAC-QOL score), postoperative complications, local recurrence rate, distant metastasis rate, 3-year tumor free survival rate and 3-year overall survival rate were compared between the two groups.Results:The operation time, intraoperative blood loss and postoperative drainage volume in the study group were lower than those in the control group: (172.28 ± 23.45) min vs. (189.57 ± 23.68) min, (177.39 ± 21.23) ml vs. (191.35 ± 22.67) ml, (342.36 ± 52.89) ml vs. (489.42 ± 63.33) ml, there were statistical differences ( P<0.05). The levels of CRP, IL-6, Cor and ACTH in the study group were lower than those in the control group: (22.35 ± 4.75) mg/L vs. (35.65 ± 5.28) mg/L, (58.74 ± 15.11) μg/L vs. (79.63 ± 20.23) μg/L, (145.36 ± 27.48) ng/L vs. (156.48 ± 32.55) ng/L, (44.58 ± 5.27) ng/L vs. (49.62 ± 5.68) ng/L, there were statistical differences ( P<0.05). The urination function and anorectal function of the patients in the study group were obviously better than those in the control group 6 months after operation, and the PAC-QOL score was obviously lower than that in the control group: (22.53 ± 2.86) scores vs. (27.54 ± 3.21) scores ( P<0.05); there was no obvious difference between the study group and the control group in the incidence of postoperative complications, local recurrence rate, distant metastasis rate, 3-year tumor free survival rate and 3-year total survival rate ( P>0.05). Conclusions:Dixon operation is effective in the treatment of low rectal cancer. It can preserve the anorectal function of patients to the greatest extent, protect urination function, reduce stress reaction of patients, and it is more conducive to rapid rehabilitation of patients.

Clinical study on Sanhuang Qingre Fuming and Washing Decoction combined with Chinese medical excision in the treatment of horseshoe perianal abscess after high position / 国际中医中药杂志

Objective:To observe the clinical effect of Sanhuang Qingre Fuming and Washing Decoction combined with Chinese medical excision in the treatment of horseshoe-shaped perianal abscess after high position and to explore its mechanism of action.Methods:Randomized controlled trial. Sixty surgical patients in our hospital from April 2020 to February 2021 were selected as observation objects. The patients were divided into two groups according to the random number table, with 30 patients in each group. Both groups were treated with Traditional Chinese Medicine drainage. On the second day after operation, the control group was treated with potassium permanganate sitz bath fumigation and washing, and the observation group was treated with Sanhuang Qingre Fuming and Washing Decoction. The wound healing time was observed in the two groups, serum TNF-α, IL-1β, IL-6, VEGF, bFGF, and EGF levels were detected by ELISA on the 1st and 7th d after operation, respectively. Serum SOD level was detected by the chemiluminescence method, and serum MDA level was detected by thiobarbituric acid method.Results:The wound healing time in the observation group was shorter than that in the control group ( t=3.37, P<0.01). The recovery rate was 93.3% (28/30) in the observation group and 76.7% (23/30) in the control group. The difference was statistically significant between the two groups ( χ2=4.32, P=0.038). Seven days after surgery, the levels of serum TNF-α, IL-1β and IL-6 in the observation group were significantly lower than those in the control group ( t values were 2.01, 2.05 and 4.88, respectively, P<0.05 or P<0.01), the level of SOD was significantly higher than that of the control group ( t=-2.13, P=0.038), the level of MDA water was significantly lower than that of the control group ( t=3.26, P=0.002), and the levels of VEGF, bFGF and EGF were significantly higher than those in the control group ( t values were -2.02, -3.33, -3.77, respectively, P<0.05). Conclusion:Sanhuang Qingre Tuming and Washing Decoction combined with Chinese medical excision in the treatment could shorten the healing time of the wound surface of horseshoe-shaped perianal abscess after high elevation and improve the recovery rate. The Sanhuang Qingre Fuming and Washing Decoction may reduce inflammatory reaction and oxidative stress damage, improve the level of growth factors and facilitate the postoperative tissue repair.

Introducción: En el tramo distal del conducto anal es normal la presencia de unas estructuras a modo de cojines, constituidas por tejido vascular, denominadas plexos hemorroidales. Objetivo: Comparar las técnicas quirúrgicas abiertas y cerrada en la enfermedad hemorroidal en la provincia Camagüey, en el periodo comprendido desde enero de 2021 a enero de 2023. Métodos: Se realizó un estudio observacional, analítico de corte transversal. El universo lo conformaron 135 pacientes que acudieron a consulta con el diagnóstico de enfermedad hemorroidal. Se le realizó un muestreo aleatorio simple, donde se tomaron 15 pacientes de cada uno de los grupos para conformar una muestra total de 45, cada grupo fue tratado con una técnica quirúrgica diferente. Resultados: En relación al sexo predominó el femenino, el tiempo quirúrgico fue dado a los 30 minutos en las técnicas abiertas. El dolor postoperatorio como complicación inmediata fue significativo con la utilización de la técnica abierta Whitehead clásico, no existieron complicaciones mediatas en el estudio; mientras que en las tardías la estenosis anal fue la que más se manifestó. Conclusiones: Existió predomino del sexo femenino, el tiempo de quirúrgico de mayor frecuencia fue de 30 minutos en los pacientes operados con la técnica abiertas, en la mayor parte de los pacientes se constató dolor excesivo como complicación inmediata con las técnicas de Milligan-Morgan y Whitehead clásico abiertas no así con la cerrada de Ferguson. La estenosis anal fue la complicación quirúrgica tardía más frecuente asociada a la técnica de Whitehead clásico.

Introduction: In the distal section of the anal canal, the presence of "cushion"-like structures, mainly made up of vascular tissue, called hemorrhoid plexuses. Objective: To compare the open and closed surgical techniques in hemorrhoid disease in Camagüey province, in the period from January 2021 to January 2023. Methods: An observational, analytical, cross-sectional study was carried out. The universe was made up of 135 patients who attended the consultation with the diagnosis of hemorrhoid disease. A simple random sampling was carried out, where 15 patients from each of the groups were taken to form a total sample of 45 patients, each group was treated with a surgical technique. Results: In relation to sex, the female sex predominated, the surgical time was given at 30 minutes in the open techniques. Postoperative pain as an immediate complication was significant with the use of the classic Whitehead open technique; there were no mediate complications in this study; while in the late ones, anal stenosis was the one that manifested itself the most. Conclusions: There was a predominance of the female sex, the most frequent surgical time was 30 minutes in patients operated with the open technique, in most patients excessive pain was found as an immediate complication with the Milligan-Morgan and classic Whitehead open techniques, but not so with the closed technique of Ferguson. Anal stenosis was the most frequent late surgical complication associated with the classic Whitehead technique.

Recurrent Appendicular Abscess-An Interesting Case Report

Background: Anorectal abscess, a common surgical condition, can rarely spread upwards to involve complex anatomical compartments leading to sepsis. A 45-year-old diabetic male presented in the ER with complaints of recurrent Right Iliac Fossa (RIF) pain with local swelling and dysuria, along with high-grade fever with chills and rigour for the last few days. He had been diagnosed with a case of recurrent appendicular abscess and treated with repeated Incision & Drainage during three previous hospitalizations. He also complained of simultaneous painful swelling in the left gluteal region during every episode of RIF pain. Methods: On examination, there was a parietal fluctuant swelling and tenderness in RIF over the previous appendicectomy scar. On Digital Rectal Examination (DRE), there was left-sided fullness and a tender induration at the 6 o'clock position on the dentate line, indicating some crypto-glandular disease. At the bedside, incision and drainage at RIF were performed, and pus was sent for C/S which came positive for an ESBL-producing strain of Escherichia coli. He was provisionally diagnosed with a case of the parietal abscess. Results: CECT W/A showed features of necrotizing fasciitis involving the anterior abdominal wall, forming an abscess, which crossed the midline along the pre-vesical space, extending to the pelvis and left ischio-anal fossa. Thus, the primary source of sepsis was a complex Ano-Rectal Abscess. Appropriate surgical management was done for source control. Conclusion: Unusual sources of infection should be suspected in patients with persistent sepsis or recurrent abscess and appropriate imaging modalities should be utilized before surgical intervention.

TYPE I CONGENITAL COLONIC POUCH RESECTION WITH TERMINAL ILEOSTOMY IN A 43-YEAR-OLD WOMAN. CASE REPORT

INTRODUCTION: Congenital colonic pouch syndrome is an extremely rare condition, particularly in Western countries. In this condition, the colon is replaced with a partially or completely abnormal pouch, connected to the genitourinary tract by a ?stula or may end in a blind pouch. As it is a congenital condition, the cases reported are found in the neonatal population, so its detection in adulthood is extremely rare. We present the CASE PRESENTATION: case of a 43-year-old female, who was admitted to the general surgery service with suspected ?stulizing CROHN's disease. She attended with a two-month clinical picture, presenting a painful ulcer in the left perianal and gluteal region, accompanied by discharge of purulent material and feces through the vaginal introitus. Laboratory tests (CAT, colonoscopy and MRI) did not present conclusive information. An exploratory laparotomy was performed, ?nding a congenital type I colonic pouch, so it was resected, and a terminal ileostomy was performed. The present case aimed to report our experience with a CONCLUSIONS: pathology that has not been reported in this particular age group in our country. Imaging studies before surgery were unable to diagnose the pathology, so the exploratory laparotomy was decisive for the treatment.

Outcome Analysis of Colostomy Closure in Different Pediatric Surgical Conditions: A Pediatric Tertiary Care Hospital Study in Bangladesh

Background: A Colostomy is a revocable surgical procedure an incision in the anterior abdominal wall and suturing it into place in which a stoma is formed by drawing the healthy end of the large intestine or colon through. This opening, in conjunction with the attached stoma appliance, provides an alternative channel for feces to leave the body. Due to anatomical defects frequently referred for closure colostomy, colostomies are often used in cases of imperforate anus and other conditions. The neonatal & children who are unable to pass feces normally and safely. pediatrics colostomy. Some neonates require emergency surgery on their tummy in the first few months of life. It is most commonly due to being born prematurely and developing a bowel problem or a blockage of the bowel. As part of this surgery, the ends of the bowel may be brought to the skin surface to divert stool into a bag called a colostomy. Intended to be temporary with reversal, later on, the stoma allows time for the bowel to rest and recover. Aim of the study: To find out the outcome analysis of colostomy closure in different pediatric surgical conditions and were reviewed to look for complications following closure colostomy.Material & Methods:This prospective was conducted in the department of Pediatrics Surgery Bangladesh Shishu Hospital & Institute, Dhaka, and Lubana General Hospital & Cardiac Center, Dhaka, Bangladesh from July 2014 to June 2021. A total of 86 patients who underwent colostomy closure were enrolled in this prospective study as the study population. Data including age, gender, surgical conditions, complications of the patients and oral feeding, and bowel preparation were all collected from the patients’ parents or hospital admission files.Results:Out of 86 cases included the age range from 8 months-10 years. There were 37(43.0%) females and 49(57.0%) males and there were more difficulties with Anorectal malformation (43.02%) than with Hirschsprung disease (40.7%). There was no record of using Necrotizing Enterocolitis, in surgical patients. The risk of wound infection and leakage was greater than any other consequence in the patients. The illness known as colostomy was predominantly encountered in men. No morbidity was recorded in this study. Conclusions:Proper stoma care, the use of well-fitting colostomy bags, and early colostomy closure enhance the prognosis. Prior to surgery, encourage thorough mechanical bowel preparation and antibiotic use. The key to a successful colostomy closure for anti-surgical diseases is appropriate IV feeding after surgery.

Prevalence and predictors of functional evacuation disorder in patients with chronic constipation

Background: Functional evacuation disorder (FED) is the second most common cause of functional constipation (FC) after constipation-predominant irritable bowel syndrome. However, the data on FED is relatively scanty in our region. Hence, the present study was performed to evaluate the demographics of FED and to find out the predictors of FED in patients with chronic constipation. Methods: A total of 134 patients with chronic constipation diagnosed according to the Rome IV criteria who were referred for high-resolution anorectal manometry (HRAM) were retrospectively enrolled in the present study. All FC patients who underwent HRAM were asked to fill a questionnaire and underwent anorectal manometry and were submitted to the balloon expulsion test (BET). Results: The mean age of patients was 43.09 ± 9.32 years old, with a total of 76 (54%) males. The most common symptom was straining during defecation (87%) followed by incomplete evacuation (86%). The prevalence of FED, diagnosed by HRAM and by the BET was 39%. Patients with FED had a significantly higher percentage of straining and sensation of anorectal blockade compared with those without FED (96 versus 82%; p < 0.01; 81 versus 44%; p < 0.001, respectively). On the multivariate regression analysis, straining > 30 minutes (odds ratio [OR] = 3.63; p = 0.03), maximum squeeze pressure (OR = 1.05; p < 0.001), and balloon volume at maximal sensation (OR = 1.06; p < 0.001) were found to be significant independent predictors of FED. Conclusion: Prolonged straining and sensation of anorectal blockade were significant indicators of FED in patients with chronic constipation. (AU)

Anal canal lymphoma: Case report and literature review / Linfoma de canal anal, reporte de caso y revisión de la literatura

Abstract Introduction: Primary tumors of the anal canal other than carcinomas are rare entities; among them, anal canal lymphomas are extremely unusual and pose both a diagnostic and therapeutic challenge for the coloproctologist. Case presentation: A male patient with positive human immunodeficiency virus (HIV) with proctalgia and mass sensation at the perianal level. A concentric thickening of the walls of the lower rectum was documented by magnetic resonance imaging, with colonoscopy and biopsies with histopathology compatible with plasmablastic lymphoma. Therefore, a diverting colostomy was performed and, subsequently, the hematology service indicated chemotherapy with the EPOCH scheme. Discussion: Lymphoma of the anus represents 0.2 % of anorectal tumors, most of these are non-Hodgkin's lymphomas; Hodgkin's disease at the anorectal level is even rarer. The population with the highest risk of this entity is HIV-positive patients, such as the patient in this case, although other associated factors are described in the literature.

Resumen Introducción: los tumores primarios del canal anal diferentes a carcinomas son entidades poco frecuentes; dentro de estos, los linfomas del canal anal son extremadamente raros y generan un reto tanto diagnóstico como terapéutico para el coloproctólogo. Presentación de caso: se presenta a continuación un caso clínico de un paciente con virus de inmunodeficiencia humana (VIH) positivo con proctalgia y sensación de masa a nivel perianal, se documentó por resonancia magnética un engrosamiento concéntrico de las paredes del recto inferior, con realización de colonoscopia y biopsias con histopatología compatible con linfoma plasmablástico, por lo que se realizó una colostomía derivativa y, posteriormente, se indicó por el servicio de hematología una quimioterapia con esquema EPOCH. Discusión: el linfoma de ano representa el 0,2 % de los tumores anorrectales, la mayoría de estos corresponde a linfomas no Hodgkin, y es aún más rara la enfermedad de Hodgkin a nivel anorrectal. La población con mayor riesgo de presentar esta entidad es los pacientes con VIH positivo, como el paciente descrito en el caso, aunque existen otros factores asociados descritos en la literatura.

Aislamiento de Neisseria meningitidis en muestra anorectal en hombre que tiene sexo con hombre con uretritis y sifilis primaria / Isolation of Neisseria meningitidis in anorectal specimen in a men who have sex with men with uretritis and primary syphilis

Resumen Neisseria meningitidis es una bacteria gramnegativa asociada frecuentemente a enfermedades invasoras de elevada mortalidad. Si bien su reservorio natural es la nasofaringe humana, en los últimos años han aumentado los aislamientos de este agente en la mucosa anorectal, principalmente en hombres que tienen sexo con hombres (HSH). Presentamos el caso de un HSH con infección por VIH, que consultó por un cuadro de uretritis y sifilis primaria, en el cual se aisló N. meningitidis en una muestra anorectal. Fue tratado en forma empírica con ceftriaxona y azitromicina, realizándose un cultivo de control post-tratamiento que fue negativo. A pesar del aumento de las infecciones y colonizaciones anogenitales por N. meningitidis, se desconoce su rol como patógeno genital, en la transmisión de otras infecciones y la necesidad de esquemas terapéuticos específicos.

Abstract Neisseria meningitidis is a Gram-negative bacterium frequently associated with invasive diseases with high mortality. Although its natural reservoir is the human nasopharynx, in recent years there have been increasing reports of isolation of this agent in the anorectal mucosa, mainly in men who have sex with men (MSM). We present the case of an HIV-positive MSM who consulted for urethritis and primary syphilis, in which N. meningitidis was isolated in an anorectal specimen. He was treated empirically with ceftriaxone and azithromycin, and a post-treatment control culture was negative. Despite the increase in anogenital infections and colonization by N. meningitidis, its role is unknown as a genital pathogen and in the transmission of other infections and the need for specific therapeutic regimens.

The diagnostic value of different methods for detecting constipation with defecation disorder based on Roman Ⅳ criteria / 西安交通大学学报(医学版)

【Objective】 To study the diagnostic value of balloon expulsion test, anorectal manometry, and colonic transit test for detecting constipation with defecation disorders. 【Methods】 Outpatients with functional constipation were retrospectively analyzed and classified into dyssynergic defecation constipation and non-dyssynergic defecation constipation according to the Rome Ⅳ diagnostic criteria. We studied the differences in symptomatological characteristics and results of the three testing methods between the two groups of patients. 【Results】 Among the 48 patients with functional constipation included, there were 13 males (27.1%) and 35 females (72.9%) with an age of (44.8±12.3) years, including 32 patients (66.7%) with defecation disorder and 16 patients (33.3%) with non-defecation disorder. The percentage of anal distension was significantly higher in patients with dyssynergic defecation constipation than in those with non-dyssynergic defecation constipation (34.4% vs. 0.0%, P=0.021). All the three tests had diagnostic value for dyssynergic defecation constipation, but with low diagnostic agreement between the results of each test. The diagnostic sensitivity of anorectal manometry was 100%, but the specificity (56.3%) was low, and both the positive predictive value (82.1%) and the negative predictive value (100%) were higher; the diagnostic sensitivity (75.0%) and specificity (81.3%) of the balloon expulsion test were both higher. The Youden index of colonic transit test was the smallest. The anal resting pressure and maximum systolic pressure of dyssynergic defecation constipation were lower than those of non-dyssynergic defecation constipation (75.2 mmHg vs. 97.1 mmHg, 168.7 mmHg vs. 251.6 mmHg). The two types of constipation did not significantly differ in anorectal pressure gradients during simulated defecation or rectal sensory function. 【Conclusion】 The balloon expulsion test can be used as a primary screening test for constipation with defecation disorders, and anorectal manometry has the highest comprehensive diagnostic value, but there is a certain false positive rate, and the colonic transit test has the lowest diagnostic efficacy. Thus a comprehensive analysis of the patient’s symptoms and the results of different tests is needed in clinical practice.

Urodynamic assessment of voiding dysfunction associated with anorectal malformation / 中华实用儿科临床杂志

Anorectal malformation (ARM) accounts for the first place of digestive tract malformations in children, with the incidence of 1/5 000-1/1 500 in newborns.ARM is typically manifested as anal stenosis or anal atresia with or without fistulas and persistent cloaca.Genitourinary malformation is the most common malformation associated with ARM, with the incidence ranging 26%-55%.There were 35%-50% of ARM children develop spinal cord peripheral abnormalities or neurogenic lower urinary tract dysfunction, which usually causes voiding dysfunction associated with ARM.Urodynamic study is the best method to analyze the changes of lower urinary tract function, which can provide an objective classification for bladder and urethral function and guide the formulation of precision treatment plan and therapeutic efficacy during the follow-up period.This study aims to review the cause of voiding dysfunction asso-ciated with ARM and its urodynamic changes.
