Introduction: Ulcerative colitis (UC) is a chronic inflammatory disease that affects the rectum and colon, involving periods of exacerbation and remission. A considerable number of patients requires surgery during the course of this disease. Objective: The purpose of this study is to analyze the profile and therapeutic approach of patients with UC. Methods: This is a retrospective study that analyzed medical records of patients diagnosed with UC between 1999 and 2010. We selected 45 patients and analyzed the following variables: age, gender, ethnic group, interval between onset of symptoms and diagnosis, extraintestinal manifestations, extent of colonic involvement, disease complications, pharmacological treatment, indication for surgery, time between diagnosis and indication, surgical procedures, early and late complications and pathological results of surgical specimens. Data were analyzed descriptively and compared with other studies. Results: The clinical profile of the patients was consistent with the literature. Nine patients underwent surgical treatment: seven were submitted to proctocolectomy with anastomosis in the ileo-anal pouch and two were submitted to total colectomy; in addition, eight were submitted to ileostomy. Postoperative complications occurred in 55.5% of patients. Conclusions: The study confirms data from the literature regarding the profile and therapeutic approach of patients with ulcerative colitis. RESUMO: Introdução:A retocolite ulcerativa (RCU) é uma doença inflamatória crônica que acomete reto e cólon, cursando com períodos de exacerbação e remissão. Uma parcela considerável de pacientes necessita de procedimento cirúrgico ao longo do curso dessa enfermidade. Objetivo: Este estudo objetiva analisar perfil e abordagem terapêutica de portadores de RCU. Métodos: Trata-se de estudo retrospectivo realizado por meio da análise de prontuários de pacientes acompanhados com diagnóstico de RCU no período de 1999 a 2010. Foram selecionados 45 pessoas, sendo analisadas as variáveis: idade, sexo, raça, intervalo entre início dos sintomas e diagnóstico, sintomatologia, manifestações extraintestinais, extensão do acometimento colônico, complicações da doença, tratamento medicamentoso, indicação de cirurgia, tempo entre esta e o diagnóstico, procedimentos cirúrgicos, complicações precoces e tardias e resultado anatomopatológico das peças cirúrgicas. Os dados foram analisados de forma descritiva e comparados com outros estudos. Resultados: O perfil clínico dos pacientes foi condizente com a literatura. Nove foram submetidos a tratamento cirúrgico, sendo realizadas sete proctocolectomias com anastomose em bolsa íleo-anal e duas colectomias totais, além de oito ileostomias. As complicações pós-operatórias ocorreram em 55,5% dos The surgical treatment of patients with ulcerative colitis from an university hospital at Natal, BrazilSuelene Suassuna Silvestre de Alencar et al.

Introduction: aggressive angiomyxoma is a highly aggressive, rare neoplasm of the mesenchymal tissue with a high recurrence rate. It represents an important differential diagnosis of pelvic tumors in women of reproductive age. This study aims to describe a case of aggressive angiomyxoma. Case report: woman, 37 years old, complained about a bulge on the right perianal region, and anal itching and burning, bleeding, tenesmus and incontinence. The proctologic examination confirmed the perianal bulge and extrinsic compression of the posterior wall of the rectum. Computed tomography (CT) of the pelvis showed a well-defined pelvic mass extending to the right rectal area. Exploratory laparotomy showed a mass of fibro elastic consistency adjacent to the pelvic organs and closely attached to the distal rectum, and performed a resection of the pelvic tumor afterward. Anatomopathological analysis revealed an aggressive angiomyxoma. Magnetic resonance imaging (MRI) of the pelvis showed signs of recurrence in the pelvic cavity on the right side of the rectum. A surgical procedure was performed to resect the lesion. After an asymptomatic period, the MRI showed solid growths located in the right ischiorectal fossa. A new surgical procedure identified only retention cysts in the pelvis and right ischiorectal fossa, only lysis of adhesions was performed. The patient is currently undergoing follow-up without disease recurrence.

Introduction Anal carcinoma is a rare variant of epithelial tumors of the anal canal. When associated with chronic and active anal fistulas, usually this is an aggressive cancer that has difficult diagnosis and poor prognosis. Anal fistulas are a common manifestation of Crohn's disease (CD). This study aims to report a case of mucinous adenocarcinoma originating from recurrent perianal fistula in patients with CD. Case report A man of 43 years, with melanoderma, complaining of perianal tumors, anal pain and mucopurulent secretion, the patient was diagnosed with fistulae. Colonoscopy revealed a chronic inflammatory process associated with villous polypoid lesion in the colonic and rectal mucosa. In a new episode, where it was diagnosed, chronic colitis of rectum and sigmoid was being prescribed sulfasalazine with improvement. There were relapses and the patient underwent repeated fistulectomias. After investigation, CD was diagnosed. Computed tomography (CT) of abdomen and pelvis showed multiple perineal and gluteal collections, and the patient underwent abdominoperineal resection of the rectum. Anatomopathological exam showed invasive mucinous adenocarcinoma. A new CT showed residual growth of the lesion. The patient was referred to the oncology referral service, where chemotherapy and radiotherapy were planned. The patient developed unfavorably, and his death occurred two months after treatment.
