Chinese expert consensus on clinical diagnosis and treatment of fecal incontinence (2022 edition) / 中华胃肠外科杂志

Fecal incontinence is one of the common diseases in the field of colorectal and anal surgery. Its etiology is complex, the treatment response is suboptimal, and there are controversies in clinical care. There is no consensus on the clinical practice of fecal incontinence in China currently. Launched by Anorectal Branch of Chinese Medical Doctor Association, Expert Committee on Anorectal Disease of Anorectal Branch of Chinese Medical Doctor Association, and Clinical Guidelines Committee of Anorectal Branch of Chinese Medical Doctor Association, and organized by the editorial board of Chinese Journal of Gastrointestinal Surgery, Chinese experts on this field were convened to write the Chinese expert consensus on clinical practice of fecal incontinence based on relevant references. After rounds of discussion, the final consensus combines the latest evidence and experts' clinical experience. This expert group suggested that a comprehensive assessment of fecal incontinence should be conducted before treatment, including medical history, relevant scales, physical examination and special examinations. Special examinations include anorectal endoscopy, anorectal manometry, transrectal ultrasound, magnetic resonance, rectal sensation and compliance, balloon ejection test, pelvic floor electromyography, defecography, colonoscopy and pudendal nerve terminal motor latency. Treatment methods include life style modification, medication, surgery, traditional Chinese medicine and other treatments. This consensus aims to standardize the algorithm of fecal incontinence management and improve therapeutic efficacy.

Chinese expert consensus on the diagnosis and treatment of outlet obstructive constipation (2022 edition) / 中华胃肠外科杂志

In recent years, professional societies in China including the Chinese Medical Doctor Association Anorectal Branch have issued many clinical practice guidelines and expert consensus on constipation, which played a positive role in the standardization of diagnosis and surgical treatment of chronic constipation in China. However, the diagnosis and treatment of outlet obstructive constipation (OOC) remain controversial. OOC, the most common subtype of functional constipation, is featured by various clinical symptoms, complex pelvic floor anatomy, functional and psychological aspects. We need a gold standard supported by high-level clinical research evidence. To standardize the diagnosis and treatment process of OOC in China, Chinese Medical Doctor Association Anorectal Branch and its Clinical Guidelines Committee, and jointly sponsored by Professional Committee on Anorectal Diseases of Chinese Society of Integrated Traditional Chinese and Western Medicine, Anorectal Disease Committee of Chinese Medical Women's Association and Chinese Constipation Medical Association, and the Chinese Journal of Gastrointestinal Surgery organized and summoned a Chinese expert taskforce to focus on OOC diagnosis, classification, examination, evaluation, and various treatments (e.g. diet modification, medication, biofeedback therapy, pelvic floor function training, psychological intervention, traditional Chinese medicine and surgical treatment). Based on the latest relevant evidence in China and abroad and experts' clinical experience, the taskforce produced the " Chinese expert consensus on the diagnosis and treatment of outlet obstructive constipation (2022 edition)" after rounds of discussion and revision. The aim is to help anorectal surgeons make clinical decisions, standardize the process of diagnosis and treatment, reduce complications and improve clinical efficacy in OOC.

Profile of Crohn's disease patients who underwent anorectal examination under anesthesia

Introduction: Crohn's disease (CD) is an inflammatory bowel disease, and in ~ 30% of cases it is associated with perianalmanifestations. To identify the extent of the damage and to implement an appropriate treatment, anorectal examination under anesthesia (EUA) is fundamental. Objective: To describe the profile of patients who underwent anorectal EUA in university and private hospitals in the state of Bahia, Brazil. Methodology: A retrospective, descriptive study with 46 patients who underwent anorectal EUA between March, 2016 and November, 2019. Results: A total of 62 anorectal EUAs were performed in 46 patients. With an average age of 36.8 years, the female gender was predominant (52.2%) among these patients. Anal fistulas were the most frequent findings (83.8%), and in most cases they were treated with a seton placement (69.4%). The main recommended surgical indication was a proper evaluation and identification of perianal disease, followed by drainage of the abscess and therefore immunobiological therapy (59.6%). Conclusion: In the present study, the profile of CD patients was similar to those found in the literature, with a high rate of complex anal fistulas. Additional studies are still necessary to further comprehend and treat this particular and debilitating manifestation of the disease. (AU)

Características manométricas en niños con estreñimiento crónico y patología anorrectal adquirida / Manometric characteristics in children with chronic constipation and acquired anorectal pathology

Objetivos: Describir los resultados de las manometrías anorrectales (MAR) en pacientes pediátricos con estreñimiento crónico y patología anorrectal adquirida. Materiales y métodos: Se revisaron los expedientes de pacientes pediátricos referidos entre 2004 y 2016 al Laboratorio de Motilidad Gastrointestinal del Hospital San José Tec de Monterrey para evaluación por manometría anorrectal y que presentaron patología anorrectal adquirida. Resultados: Se revisaron 170 expedientes. Edad 7,18 ± 4,51 años. La prevalencia de patología anorrectal (PA) fue de 73%. Síntomas con mayor incidencia: dificultad para evacuar (78%), dolor al evacuar (67%), heces duras (50%) e incontinencia fecal asociado (49%). El 44% de los pacientes con esfínter anal externo (EAE) hipotónico presentaron incontinencia y 74% estos últimos, presentaron menor volumen máximo tolerable (VMT). Los valores manométricos con mayor significancia: presión en reposo del EAE (promedio ± DE) 14,16 ± 10,19 en PA y de 26,08 ± 13,65 en SPA; presión en contracción del EAE 48,4 ± 34,1 en PA y 68,3 ± 37,7 en SPA; VMT 120,8 ± 60,4 en PA y de 173,2 ± 78,0 en SPA. El 97,97% de los pacientes en los que se evaluó la coordinación abdomino-pélvica tuvieron disinergia del piso pélvico. Conclusiones: A diferencia de la población adulta, los valores manométricos de niños con patología anorrectal se encontraron dentro de rangos normales excepto por el EAE y el VMT los cuales estuvieron disminuidos. Esto puede sugerir un mecanismo diferente en la población pediátrica. La disinergia del piso pélvico podría explicar el estreñimiento crónico en estos pacientes.

Objective: To describe the anorectal manometry results in the pediatric population with chronic constipation and acquired anorectal disease. Materials and methods: We reviewed the records of children who were referred to the Motility and Pelvic Floor Laboratory of the Hospital San Jose Tecnologico de Monterrey between 2004-2016 for further evaluation with anorectal manometry and who presented acquired anorectal disease. Results: We reviewed 170 records. The mean age was 7.18 ± 4.51 years old. The prevalence of anorectal disease was 73%. The symptoms more frequently presented were difficult evacuation (78%), painful defecation (67%), large and hard stool (50%) and fecal soiling (49%). 44% of patients with hypotonic external anal sphincter (EAS) presented with soiling and 74% of those had diminished critical volume. Significant manometric values (p<0.05) were EAS resting pressure, maximal squeeze pressure, and critical volume. 97.7% of those who underwent abdomino pelvic coordination evaluation had pelvic floor dyssynergia (anismus). Conclusions: Contrary to adult population, the manometric values in children with acquire anorectal pathology were within normal values except for the EAS resting pressure and critical volume that were diminished. This could suggest a different mechanism in the pediatric population. Pelvic floor dyssynergia could explain chronic constipation in these patients.

Endometriosis extrapélvica semejando cáncer colorrectal estenosante: Reporte de dos casos / Colorectal cancer endometriosis resembling stenosing extrapelvic: Report of two cases

Presentamos a dos mujeres -de 40 y 42 años- con endometriosis colorrectal, ambas con antecedente de endometriosis pélvica y episodios de rectorragia simultáneos con la menstruación. En las evaluaciones endoscópicas detectamos una tumoración sigmoidea y una tumoración rectosigmoidea respectivamente, que aparentaron corresponder a cáncer colorrectal estenosante de origen epitelial.

We present two women of 40 and 42 years with colorectal endometriosis, both with a history of pelvic endometriosis and simultaneous episodes of rectal bleeding with menstruation. In endoscopic evaluations detected a sigmoid tumor and rectosigmoid tumor respectively, which apparently corresponds to stenosing colorectal cancer of epithelial origin.

Massive Life-threatening Lower Gastrointestinal Hemorrhage Caused by an Internal Hemorrhoid in a Patient Receiving Antiplatelet Therapy: A Case Report / 대한소화기학회지

A Dieulafoy lesion in the rectum is a very rare and it can cause massive lower gastrointestinal bleeding. An 83-year-old man visited our hospital. He had chronic constipation and had taken aspirin for about 10 years because of a previous brain infarction. He was admitted because of a recent brain stroke. On the third hospital day, he had massive hematochezia and suddenly developed hypovolemic shock. Abdominal computed tomography showed active arterial bleeding on the left side of the mid-rectum. Emergency sigmoidoscopy showed an exposed vessel with blood spurting from the rectal wall. The active bleeding was controlled successfully by an injection of epinephrine and two hemoclippings. On the fourth day after the procedure, he had massive recurrent hematochezia, and his vital signs were unstable. Doppler-guided hemorrhoidal artery band ligation was performed urgently at two sites. However, he rebled on the third postoperative day. Selective inferior mesenteric angiography revealed an arterial pseudoaneurysm in a branch of the superior rectal artery, as the cause of rectal bleeding, and this was embolized successfully. We report a rare case of life-threatening rectal bleeding caused by a Dieulafoy lesion combined with pseudoaneurysm of the superior rectal artery which was treated successfully with embolization.

Tumor rectal como presentación de sífilis primaria / Rectal tumor as a presentation of primary syphilis

In the era of HIV infection there is a resurgence of syphilis. Without a doubt it is still a diagnostic dilemma in various clinical situations such as anorectal syphilis in HIV patients. When a patient HIV-positive presents with a rectal tumor, syphilis must be considered in the differential diagnosis. We present a case report of an HIV positive patient who consulted due to rectal tenesmus associated to rectal bleeding, being diagnosed a rectal tumor and treated secondary to primary syphilis.

En la era de la infección por VIH, ha habido un resurgimiento de enfermedades en franca disminución en el mundo occidental como sífilis. Sin lugar a dudas siguen siendo un dilema diagnóstico algunas manifestaciones clínicas como sífilis rectal en pacientes portadores de VIH. Frente a un tumor rectal en un paciente VIH se debe tener en cuenta en el diagnóstico diferencial a esta patología. Presentamos un caso de un paciente portador de VIH que consultó por tenesmo rectal asociado a rectorragia, siendo diagnosticado un tumor rectal secundario a sífilis primaria.

Solitary rectal ulcer syndrome: uncommon cause of rectal bleeding in children.

Rectal polyp and hemorrhoids are common causes of bleeding per rectum in pediatric age group. However, there are some other causes which should be considered in differential diagnosis. We have acquainted a case of rectal bleeding due to solitary rectal ulcer in a child of 10 year. Colonoscopic examination was required for diagnosis as proctoscopic examination and digital rectal examination missed the diagnosis, probably due to poor co-operation by the patient and rare nature of the disease. Although well recognized in the adult population, the pediatric experience with this condition is limited.

Postmenopausal intestinal obstructive endometriosis: case report and review of the literature / Endometriose intestinal obstrutiva na pós-menopausa: relato de caso e revisão da literatura

CONTEXT: Endometriosis is characterized by the presence of endometrial tissue outside the uterine cavity, which is commonly detected in gynecological practice but rarely reported as a coloproctological disorder. The objective of the present report was to discuss a rare case of postmenopausal intestinal endometriosis simulating a malignant lesion, following a review of the literature. CASE REPORT: A 74-year-old woman with complaints of hematochezia and tenesmus of two months' duration accompanied by liquid feces and pelvic pain, but with no other gastrointestinal or gynecological complaints, was referred to our service. She had been menopausal for 22 years, with no hormone replacement treatment, and had undergone panhysterectomy three years before the referral to us, due to endometrial thickening and a right adnexal cyst. Five months before this referral, she had undergone laparotomy due to acute obstructive abdomen, which revealed a tumor mass involving the small bowel. Anatomopathological examination of the enterectomy suggested a hypothesis of intestinal endometriosis. A proctological examination was normal. Computed tomography of the pelvis revealed thickening of the rectosigmoid transition and colonoscopy revealed friable tumor formation in the rectum. A biopsy of the lesion revealed mucosal fragments of endometrial type, which led to a review of the previous anatomopathological examination. The patient underwent rectosigmoidectomy with protective transversotomy, with a good postoperative course, and anatomical examination confirmed the intestinal endometriosis. The patient subsequently suffered a stenosing recurrence of the lesion and has undergone colostomy since then.

CONTEXTO: A endometriose caracteriza-se pela presença de tecido endometrial fora da cavidade uterina, e a etiopatogenia ainda apresenta controvérsias. O objetivo desta publicação é apresentar e discutir, após revisão da literatura, um raro caso de endometriose intestinal na pós-menopausa que simulava uma lesão maligna. RELATO DE CASO: Mulher de 74 anos apresentou-se com queixas de hematoquezia e tenesmo há dois meses. Relatou também aparecimento de fezes líquidas e dor pélvica no mesmo período, negando outras queixas gastrointestinais ou ginecológicas. Como antecedentes de interesse, revelou que era menopausada há 22 anos, sem terapia de reposição hormonal e realizou uma pan-histerectomia há três anos por espessamento endometrial e cisto anexial direito. Há cinco meses foi submetida a laparotomia exploradora por abdome agudo obstrutivo, com o achado de uma massa tumoral envolvendo alças de delgado. O exame anatomopatológico da enterectomia sugeriu a hipótese de endometriose intestinal. O exame proctológico era normal. A tomografia computadorizada da pelve mostrou um espessamento da transição retossigmóide e a colonoscopia, uma tumoração friável e estenosante no reto alto. A biópsia da lesão revelou fragmentos de mucosa tipo endometrial, que motivou a revisão do anatomopatológico anterior. A paciente foi submetida a retossigmoidectomia abdominal com transversostomia protetora, tendo boa evolução no pós-operatório. O anatomopatológico confirmou endometriose intestinal. Evoluiu com recidiva estenosante da lesão e pemanece colostomizada desde então.

A Case of Primary Syphilis in the Rectum

A 30-yr-old man was referred for suspicious rectal cancer because of ulcerated lesions in the rectum and a palpable mass in left inguinal area. Sigmoidoscopy showed two indurated masses and histologic evaluation of biopsy revealed obliterative endarteritis with heavy plasma cell infiltration. Both venereal disease research laboratories (VDRL) and fluorescent treponemal antibody absorption (FTA-ABS) tests were positive. After injection of penicillin G benzathine for 3 weeks, the rectal chancre and the palpable mass disappeared.

Endoscopic band ligation for non variceal bleed.

Endoscopic band ligation (EBL) is an infrequently used modality for treatment of non-variceal hemorrhage. We report the successful use of this technique for the management of bleed from blue rubber bleb nevus syndrome lesions and post polypectomy bleeding stalk.

Imágenes en anomalias anorectales / Anorectal malformations images

Las malformaciones anorectales incluyen una amplia variedad de anomalías, de grados variables de complejidad, que con frecuencia se presentan asociadas a otras malformaciones: genitourinarias, espinales, cardíacas, esofágicas y de la pared abdominal entre las más habituales. Las imágenes diagnósticas tienen un importante rol en el estudio de estos pacientes, que está orientado a demostrar adecuadamente la anatomía de la malformación y, por otra parte, precisar la existencia de anomalías asociadas. El examen más utilizado inicialmente en el estudio de pacientes con malformaciones anorectales es el ultrasonido, que posteriormente se complementará con colografía distal, uretrocistografía y resonancia magnética de acuerdo a la condición clínica de cada paciente.

Significance of rectosigmoid polyp as a predictor of proximal colonic polyp

The association between rectosigmoid polyps and polyps in the more proximal colon is still a matter of debate, and the need for colonoscopy in patients with rectosigmoid polyps that are detected by flexible sigmoidoscopy is controversial. The aim of this study was to determine whether or not certain characteristics of rectosigmoid polyps are associated with the presence and characteristics of proximal colonic polyps. Seven hundred and twenty-eight patients who underwent total colonoscopy between October 1995 and June 1998 and who had colorectal polyps were retrospectively analyzed. Patients with inflammatory bowel diseases, familial adenomatous polyposis, or any advanced cancer were excluded. The odds ratio (OR) and 95% confidence interval (CI) of prevalence of proximal colonic polyps according to the patients age and sex, as well as the characteristics of rectosigmoid polyps, were calculated. Advanced adenoma was defined as an adenoma larger than 10 mm or an adenoma of any size with villous component, high-grade dysplasia or invasive carcinoma. Among 728 patients with colorectal polyps, 356 patients (48.9%) had polyps only in the rectosigmoid region, 193 patients (26.5%) had polyps only in the proximal colon, and 179 patients (24.6%) had polyps in both the rectosigmoid and proximal colon. In 535 patients with rectosigmoid polyps, the prevalence of proximal colonic polyps, neoplastic polyps and advanced adenomas were 33.4%, 27.3% and 2.9%, respectively. The prevalence of proximal colonic polyps in patients with rectosigmoid polyps was found to be significantly related to the male gender and elderly patients, in addition to the neoplastic histology of the rectosigmoid polyps. However, the prevalence of the proximal colonic polyps was not related to the size, number and shape of rectosigmoid polyps. In 179 patients with both rectosigmoid and proximal colonic polyps, the characteristics of proximal colonic polyps such as size, number and shape were similar to those of rectosigmoid polyps. We recommend total colonoscopic examination in all patients with rectosigmoid adenomas, regardless of the size, number, and shape, especially in elderly males.

Gangrena de Fournier / Fournierïs gangrene

Se analiza la experiencia en el manejo de 11 pacientes atendidos por gangrena de Fournier en el período 1992-1997 en nuestro servicio. El origen de la gangrena fue por absceso anorrectal en un 73 por ciento y uropatía obstructiva en un 18 por ciento. De los 8 pacientes con absceso anorrectal, 4 habían sido drenados antes de la presentación de la gangrena, siendo todos ellos diabéticos. El 81 por ciento de los pacientes presentaba al menos una patología asociada predisponente, siendo la diabetes la más habitual. Se rescataron cultivos de herida operatoria en 9 pacientes siendo todos positivos para aerobios y 5 para anaerobios. Se realizó aseo quirúrgico en 10 pacientes, practicándose colostomía en 3 pacientes y cistostomía en 2. Un paciente recibio 10 sesiones de terapia con oxígeno hiperbárico (OHB), evolucionando sin complicaciones. Fallecieron 3 pacientes (27 por ciento), todos por falla orgánica múltiple. La gangrena de Fournier es aún una patología de alta mortalidad. Se requiere un drenaje amplio y precoz de los abscesos anorrectales especialmente en pacientes diabéticos, o con algún otro factor predisponente, ya que son éstos los que generalmente llegan a la gangrena. El manejo o apoyo de estos pacientes por cirujanos con experiencia en su tratamiento es fundamental

Affecçöes colorretais em portadores da síndrome da imunodeficiência adquirida e suas manifestaçöes endoscópicas / Colorectal diseases in AIDS patients and its endoscopic findings

Com a finalidade de se estabelecer as principais afecçoes colorretais observadas em pacientes portadores da síndrome da imunodeficiência adquirida com sintomas intestinais e verificar as alteraçoes endoscópicas relacionadas, foi analisada uma série de 236 colonoscopias realizadas em 186 pacientes. A colonoscopia foi sempre acompanhada de biopsias, mesmo quando nao havia alteraçoes endoscópicas. O diagnóstico mais freqüente foi colite pelo citomegalovírus identificado em 64 exames (27,1 por cento) e se apresentou caracteristicamente com padrao inflamatório ulcerativo. O segundo achado em freqüência foi o Cryptosporidium sp. observado em 31 exames (13,1 por cento), relacionando-se o processo inflamatório sem ulceraçoes. Outros patógenos observados com menor freqüência foram: Mycobacterium sp., Histoplasma capsulatum, Herpes simplex, Isospora sp. Giardia sp., Candida sp. e Campilobacter sp.. As afecçoes neoplásicas foram diagnosticadas em 10 exames (4,2 por cento) e representadas principalmente pelo sarcoma de Kaposi. Os autores concluem que: 1. as afecçoes colorretais mais freqüentes em portadores da AIDS (CMV e Cryptosporidium sp.) apresentam, na maioria das vezes, aspecto colonoscópico característico que podem sugerir diagnóstico; 2. a realizaçao de biopsias é fundamental: a) para confirmaçao diagnóstico; b) para realizaçao do diagnóstico quando da ausência de alteraçoes endoscópicas; c) para identificar a eventual concomitância de patógenos.

Complicaciones infecciosas de la enfermedad inflamatoria anorrectal / Infectious complications of the inflammatory anorectal disease

Introducción. Las infecciones de la región anorrectal puede ser un problema grave y a menudo se asocian con falla orgánica múltiple. Objetivo. Presentar nuestra experiencia sobre infecciones anorrectales en un hospital de tercer nivel de atención en la ciudad de México. Pacientes y métodos. Analizamos retrospectivamante los datos de todos los pacientes que ingresaron consecutivamente a un Hospital de Infectología de tercer nivel de atención de 1991 a 1994. Se evaluó la edad, sexo severidad de la enfermedad, enfermedades asociadas, gérmenes aislados y mortalidad. Resultados.
