Granskning av riktlinjer vid Sveriges förlossningskliniker gällande sfinkterskada i samband med förlossning : Innehållsanalys med en kombination av en deduktiv och induktiv ansats

Background: Sphincter injury is serious complication in connection to vaginal childbirth. Desire to avoid vaginal birth again is seen in women who previously suffered from a sphincter injury. Objective: To identify and evaluate obstetric guidelines in Sweden regarding sphincter injury in relation to childbirth Method: Content analysis with a combination of a deductive and inductive approach. Results: The most frequently occurring risk factors and prevention with help of perineal protection were described in the guidelines. The physician made diagnosis and repaired the sphincter injury at the theatre.  Complications such as coital pain and anal incontinence were described in the guidelines. Paracetamol and diclofenac was most common analgesic regimen given for pain. Prophylaxis such as antibiotic treatment and laxative were common. Information given to women was described. Follow-up by physician, midwife and physiotherapist was recommended after four weeks to six months. For future birth a cesarean section was recommended. Conclusion: The guidelines were constructed in the same way and had to a large extent similar content. The authors of the present work recommend a national guideline.

Variation of the anal resting pressure induced by postexpiratory apnea effort in patients with constipation

CONTEXT: Intestinal constipation - a common symptom among the general population - is more frequent in women. It may be secondary to an improper diet or organic or functional disturbances, such as dyskinesia of the pelvic floor. This is basically characterized by the absence of relaxation or paradoxical contraction of the pelvic floor and anal sphincter during evacuation. OBJECTIVE: To analyze, by manometric data, the anal pressure variation at rest, during evacuation effort by using the Valsalva maneuver and forced post-expiratory apnea in subjects with secondary constipation. METHODS: Twenty-one patients (19 females - 90.4%) with a mean age of 47.5 years old (23-72) were studied. The diagnosis was performed using anorectal manometry, with a catheter containing eight channels disposed at the axial axis, measuring the proximal (1) and distal (2) portions of the anal orifice. The elevation of the pressure values in relation to the resting with the evacuation effort was present in all patients. The Agachan score was used for clinical evaluation of constipation. The variables studied were: mean anal pressure of the anal orifice for 20 seconds at rest, the effort of evacuation using Valsalva maneuver and the effort of evacuation during apnea after forced expiration, as well as the area under the curve of the manometric tracing at moments Valsalva and apnea. RESULTS: The analysis of the mean values of the anal pressure variation at rest evidenced difference between proximal and distal channels (P = 0.007), independent of the moment and tendency to differ during moments Valsalva and apnea (P = 0.06). The mean of values of the area under the manometric tracing curve showed differences between moments Valsalva and apnea (P = 0.0008), either at the proximal portion or at the distal portion of the anal orifice. CONCLUSION: The effort of evacuation associated with postexpiratory apnea, when compared with the effort associated with the Valsalva maneuver, provides lower elevation of anal pressure at rest by the parameter area under the curve.

Evolução dos doentes com citologia oncótica alterada e colposcopia anal normal

A citologia anal vem sendo usada para rastreamento do carcinoma anal e suas lesões precursoras nas populações de risco. Quando o raspado do canal anal mostra alterações citológicas está indicada o exame com colposcópio e ácido acético para identificar e realizar biópsia para confirmar o achado. Poucos estudos mostram o seguimento dos doentes tratados de condilomas acuminados perianais. Temos usado os métodos em associação e encontrado lesões subclínicas em metade dos doentes, cujo exame proctológico não revelava doença HPV induzida. Essas lesões são tratadas com tópicos. Entretanto, algumas citologias estavam alteradas e a colposcopia anal não revelou doença HPV induzida. O objetivo deste estudo foi observar o comportamento dessas lesões no seguimento semestral, durante 12 meses, e avaliar se a periodicidade da reavaliação foi suficiente para evitar o aparecimento das lesões de alto grau ou superior. Encontramos 58 (21%) entre 273 doentes nessas condições. As reavaliações de 22 deles após um ano mostraram que as colposcopias permaneceram normais em 17 (74%), sendo que em cinco (22%) a citologia voltou aos padrões normais e 12 (52%) persistiram com alterações. Os outros seis (26%) desenvolveram lesões clínicas ou subclínicas provocadas pelo HPV. As contagens de linfócitos T CD4 dos doentes HIV-positivos foram inferiores nos doentes cujas lesões progrediram. Os resultados permitiram concluir que as alterações podem progredir ou regredir neste grupo distinto de doentes, sendo relacionada à imunidade, e que o intervalo de seis meses é suficiente para cada reavaliação.

Avaliação manométrica anal de crianças com encoprese

INTRODUÇÃO: A constipação crônica é doença comum na infância, ocorrendo em 5 a 10% dos pacientes pediátricos, considerada a segunda maior causa de procura nos consultórios de pediatria, sendo a encoprese decorrente de constipação grave associada à impactação fecal no reto. Dentre os exames diagnósticos, a manometria anal é utilizada para a avaliação de pacientes com distúrbios funcionais, como a constipação intestinal e a incontinência fecal, em alguns serviços para a avaliação de pacientes com encoprese, pois pode trazer informações sobre o mecanismo evacuatório e possíveis lesões esfincterianas anais. OBJETIVO: Verificar alterações manométricas em pacientes com encoprese. MÉTODOS: Foi realizado estudo de 40 manometrias anais de crianças constipadas com encoprese (G1) e 12 crianças constipados sem encoprese (G2). Foram obtidos os seguintes dados: pressões de repouso, contração e evacuação do canal anal e ampola retal, ponto de maior pressão, reflexo inibitório anal e sensibilidade retal. As manometrias foram realizadas com o aparelho Alacer de perfusão com 8 canais. RESULTADOS: Não foram encontradas diferenças nas pressões de repouso, contração e evacuação do canal anal entre os grupos. Chamou-nos a atenção a ausência de necessidade de maior volume retal para desencadear o reflexo inibitório anal. Não houve diferença da incidência de anismus entre os dois grupos, demonstrando que não se trata de fator importante na manutenção da encoprese, mas sim da constipação. CONCLUSÃO: Não houve necessidade de maior volume para desencadear o reflexo inibitório anal. O anismus não foi diferente entre os dois grupos, não sendo importante na manutenção da encoprese.

Early and Late Results of Topical Diltiazem and Bethanechol for Chronic Anal Fissure: A Comparative Study

Background/Aims: Late efficacy of medical treatment of chronic anal fissure remains controversial due to high recurrence. This study aimed at analyzing safety and efficacy of topical diltiazem and bethanechol regarding healing and symptoms relief, safety, recurrence, and need for surgery. Methodology: This was a single-center non-randomized trial. Outcomes of 30 patients with chronic anal fissure treated with 2% diltiazem were compared to 30 patients treated with 0.1% bethanechol, both for eight weeks. Patients were assessed after seven days and eight weeks. Results: In diltiazem group, after seven days, 31% were symptomatic; after bethanechol, 71% (p=0.06). After seven days, fissure healing occurred in 19% after diltiazem and in 11% after bethanechol. After eight weeks, in both groups, 64% were asymptomatic; after diltiazem, 53% healed; after bethanechol, 50% (p=0.80). Success was the same for both groups: 63.3%. Groups were similar regarding complications. After diltiazem, 9 (30%) patients were operated on; and 11 (36.7%) after bethanechol (p=0.60). Recurrence occurred in 4 (13.3%) patients in both groups. Median time to recurrence after diltiazem was 15 (10-24) months and 7.5 (2-15) after bethanechol - p=0.15. Conclusions: Both treatments are safe and effective. Diltiazem may be associated to earlier relief and more sustained response.

Screening Anal Dysplasia in HIV-Infected Patients: Is There an Agreement Between Anal Pap Smear and High-Resolution Anoscopy-Guided Biopsy?

PURPOSE: The purpose of this study was to analyze the agreement between anal Pap smear and high-resolution anoscopy-guided biopsy in diagnosing anal dysplasia in HIV-infected patients. METHODS: We conducted cross-sectional analysis of HIV-infected patients receiving anal dysplasia screening as part of routine care. Agreement between measures was estimated by weighted kappa statistics, using a three-tiered cytologic and histologic grading system (normal, low-grade dysplasia, and high-grade dysplasia). Estimates of sensitivity, specificity, and predictive values were calculated using a two-tiered cytologic and histologic grading system (""without dysplasia"" and ""with dysplasia of any grade""). Estimates were also calculated for the detection of high-grade dysplasia. RESULTS: During a one-year period, 222 patients underwent 330 anal Pap smears followed by high-resolution anoscopy-guided biopsies. There were 311 satisfactory Pap smears with concurrent biopsies. Considering histology the standard, the frequency of anal dysplasia was 46%. Kappa agreement between anal Pap smear and biopsy was 0.20. For detection of anal dysplasia of any grade, anal Pap smear showed sensitivity of 61%, specificity of 60%, positive predictive value of 56%, and negative predictive value of 64%. For high-grade dysplasia, anal Pap smear showed sensitivity of 16% and specificity of 97%. CONCLUSION: Anal Pap smears alone were not sensitive enough to rule out anal dysplasia. We recommend that high-resolution anoscopy-guided biopsy be incorporated as a complementary screening test for anal dysplasia in high-risk patients. Following baseline high-resolution anoscopy, these individuals could be followed with serial anal cytology to dictate the need for future high-resolution anoscopy-guided biopsies.

Anal Incontinence Improvement After Silicone Injection May Be Related to Restoration of Sphincter Asymmetry

Background. This study aimed to evaluate manometric parameters that may explain improvement in anal incontinence using a silicone bulking agent. Methods. Incontinent patients having internal sphincter defects were prospectively selected and injected with a silicone bulking agent. Manometry and endoanal ultrasound were performed before and 3 months after injections. Twenty continent healthy volunteers were used only for manometric comparison. Results. Thirty-five patients (28 females; mean age 60.3 years) and 20 controls entered this study. Patients had lower resting and squeeze pressures compared with controls (P<.05). Length of the high-pressure zone increased from 1 to 1.7 cm postinjection (P=.002). Asymmetry index showed a significant change postinjection (P<.001). Conclusion. Despite considerable clinical improvement, no significant increase in manometric pressures was noted posttreatment. There was significant improvement in both high-pressure zone and asymmetry index, and these findings may explain the mechanism of action of the bulking agent injected.

Anal squamous carcinoma: a new AIDS-defining cancer? Case report and literature review

Squamous anal cell carcinoma is a rare malignancy that represents the 1.5% to 2% of all the lower digestive tract cancers. However, an increased incidence of invasive anal carcinoma is observed in HIV-seropositive population since the widespread of highly active antiretroviral therapy. Human papillomavirus is strongly associated with the pathogenesis of anal cancer. Anal intercourse and a high number of sexual partners appear to be risk factors to develop anal cancer in both sexes. Anal pain, bleeding and a palpable lesion in the anal canal are the most common clinical features. Endo-anal ultrasound is the best diagnosis method to evaluate the tumor size, the tumor extension and the infiltration of the sphincter muscle complex. Chemoradiotherapy plus antiretroviral therapy are the recommended treatments for all stages of localized squamous cell carcinoma of the anal canal in HIV-seropositive patients because of its high rate of cure. Here we present an HIV patient who developed a carcinoma of the anal canal after a long time of HIV infection under highly active antiretroviral therapy with a good virological and immunological response.

Doença de Crohn Gastro-Duodenal Ileo-Cólica e Peri-Anal

Os autores apresentam um caso de D. Crohn que inicialmente envolveu localizações comuns, e mais tarde um envolvimento raro - gastro-duodenal. Na altura do diagnóstico definitivo deste último, havia já sinais de obstrução à saída do estômago. A terapêutica com Prednisolona IM e Omeprazole não teve qualquer sucesso, havendo necessidade de recorrer à Cirurgia, como último recurso para resolução da obstrução. Faz-se uma revisão teórica sobre os principais aspectos clínicos, de diagnóstico e terapêutica desta forma rara de envolvimento da D. Crohn.

Anal paracoccidioidomycosis: an unusual presentation of disseminated disease

We report a patient with an unusual anal ulceration. The biopsy of an anal lesion and subsequent studies revealed a disseminated form of paracoccidioidomycosis, observed in the lungs, small and large bowel. The anorectal disease frequently represents a secondary site of disease, and the patient must be better evaluated.
