1. Avaliação do perfil microbiológico e dos fatores de risco relacionados ao desenvolvimento de bolsites em pacientes com bolsa ileal por retocolite ulcerativa / Microbiological assessment and risk factors related to developing pouchitis in patients with Ileal pouch-anal anastomosis by ulcerative colitis
INTRODUÇÃO: A bolsite tem sido descrita como a complicação mais comum após a realização de bolsa ileal por retocolite ulcerativa. A etiologia da bolsite não está clara, mas sua resolução ocasional com metronidazol e/ou ciprofloxacina sugere que a estase fecal e a superproliferação bacteriana possam estar envolvidas na sua patogênese. Poucos est

2. Histopathological evaluation and risk factors related to the development of pouchitis in patients with ileal pouches for ulcerative colitis
OBJECTIVE: Many changes in mucosal morphology are observed following ileal pouch construction, including colonic metaplasia and dysplasia. Additionally, one rare but potential complication is the development of adenocarcinoma of the reservoir. The aim of this study was to evaluate the most frequently observed histopathological changes in ileal pouches and to

3. Inflammatory and apoptosis pathway in ileal pouches of patients with ulcerative colitis and familial adenomatous polyposis / Estudo da atividade inflamatoria e apoptose em reservatorios ileais de doentes operados por polipose adenomatosa familiar e retocolite ulcerativa inespecifica
Ileal pouch-anal anastomosis is the surgical procedure of choice for patients with refractory ulcerative colitis (UC) and for familial adenomatous polyposis (FAP) with rectal polyps. Pouchitis is the most common complication in UC, while it is quite rare in FAP. Objective: Evaluate the inflammatory and apoptotic activity in endoscopically normal ileal pouch

4. Complicações imediatas e tardias após cirurgia de reservatório ileal na polipose adenomatosa familiar
RACIONAL: A retocolectomia total com confecção de reservatório ileal é cirurgia ideal para o tratamento do cólon e reto dos doentes com polipose adenomatosa familiar, no entanto pode estar associada a complicações no pós-operatório imediato e tardio. OBJETIVO: Estudar as complicações pós-operatórias da cirurgia do reservatório ileal na polipose

5. Expressão das citocinas pro-inflamatorias TNF-alfa, IL-1beta, IL-6, IL-8, da proteina pro-apoptotica pBad e ativação do fator de transcrição NF-KB em reservatorios ileais de doentes operados por retocolite ulcerativa inespecifica e por polipose adenomatosa familiar / Expression of proinflammatory cytokines TNF-alfa, IL-1beta, IL-6, IL-8, pro-apoptotic protein pBad and activation of transcription factor NF-KB in ileal puches of patients with ulcerative colitis and familial adenomatous polyposis
Pouchitis after total retocolectomy is the commonest complication in ulcerative colitis (UC), while is quite ra re in familial adenomatous polyposis (FAP). Objective: To evaluate the inflammatory activity in endoscopically normal ileal pouc h mucosa, by determining the expressions of IL-1?, IL-6, IL-8, TNF-?, a pro-apoptotic protein, p-Bad and the activation

6. Retocolectomia total e anastomose íleo-anal com reservatório ileal: experiência de 16 anos
O reservatório ileal pélvico tem sido a melhor opção cirúrgica para a retocolite ulcerativa (RCU) e polipose adenomatosa familiar (PAF). Desde 1983 esta técnica vem sendo empregada, e o objetivo deste trabalho é apresentar revisão desta casuística, analisando seus resultados e seus pontos controversos. Setenta e três pacientes, com média de idade

7. Crypt cell proliferation and HLA-DR expression in pelvic ileal pouches.
To investigate the nature of the morphological changes that occur in ileal pouches, 26 biopsy specimens from patients with functioning ileo-anal pouches (eight with pouchitis) were studied. Normal ileum (n = 10) was used as a control. Mucosal morphometry (using linear measurements), crypt cell proliferation (CCP) (using the monoclonal antibody Ki67), and epi

8. Microbiologic assessment of tissue biopsy samples from ileal pouch patients.
Tissue biopsy samples from patients with and without ileal pouches were examined by electron microscopic and microbiologic culture techniques to determine the numbers and types of microorganisms closely associated with or within the tissue biopsy samples. The disease status of each patient was determined by endoscopic and histopathologic methods. Of the 78 b

9. Axonal necrosis of enteric autonomic nerves in continent ileal pouches. Possible implications for pathogenesis of Crohn's disease.
OBJECTIVE: Axonal necrosis was first described in samples of small intestine from patients with Crohn's disease (A.M. Dvorak et al. Hum Pathol 1980; 11:620-634). Clinically evident inflammation of continent ileal reservoirs (pouches) has clinical features that resemble Crohn's disease. Possible similarities in the pathogenesis of Crohn's disease and pouchiti

10. Preoperative terminal ileal and colonic resection histopathology predicts risk of pouchitis in patients after ileoanal pull-through procedure.
OBJECTIVE: This study seeks to compare the histopathology of preoperative terminal ileal and colonic resection specimens with pouch biopsies after the ileoanal pull-through (IAPT) procedure. SUMMARY BACKGROUND DATA: Pouchitis is the most frequent complication of transanal continent reservoirs in patients after IAPT. METHODS: The authors conducted 751 consecu

11. Contribution of gastrointestinal transit and pouch characteristics in determining pouch function.
AIM: To determine the contributions of gastrointestinal transit and pouch characteristics to bowel frequency in patients with an ileoanal reservoir and no pouchitis. METHODS: Twenty one patients who had undergone restorative proctocolectomy, with ileostomy closure at least eight months previously, and who had no history of pouchitis were recruited. They were

12. Expression of colonic antigens by goblet and columnar epithelial cells in ileal pouch mucosa: their association with inflammatory change and faecal stasis.
AIMS--To investigate colonic metaplasia of goblet and columnar epithelial cells in ileal pouch mucosa; to correlate this with the degree of morphological and inflammatory change; and to assess whether such changes are related to the presence of faecal stasis. METHODS--Biopsy specimens of ileal pouch mucosa were taken from 31 patients (30 with ulcerative coli
