ABDÔMEN AGUDO

The acute abdomen is one of the major and most frequently occurring syndromes in clinical practice and, since it can be caused by various different diseases, it demands an urgent diagnosis and treatment. The present text expatiates upon the different etiopathogeneses of this syndrome as well as upon its bases, which are crucial for the diagnosis and treatment of an acute abdomen.O abdome agudo configura um quadro clínico de dor dos mais importantes e freqüentes na prática clínica. Pela sua gravidade necessita de condutas diagnósticas e terapeuticas urgentes. Pode ser decorrente de inúmeras doenças. O texto discorre sobre diferentes etiopatogenias e as bases do quadro clínico, essenciais para o diagnóstico e tratamento

The epidemiological and clinical features of familial adenomatous polyposis in Ribeirão Preto

AbstractPurposeto study 75 familial adenomatous polyposis (FAP) patients treated in a single insti- tution in Ribeirão Preto/SP, from January 1981 to December 2011.Methodsthis is a retrospective study and the following data were collected: gender, age, main symptoms, familial history, coexisting malignancies, surgical treatment, surgical morbidity and mortality, factors related to life quality.Resultsmedian age was 29 years. Male-to-female ratio was 1.2:1. Bleeding was the most common symptom (62.6%). Colorectal cancer incidence was 25.5% (n = 19). Extracolonic neoplasia incidence was 8%. Colectomy with ileorectal anastomosis (IRA) was performed in 72% of the patients. Eighteen patients (24%) were submitted to proctocolectomy with “J-pouch” ileoanal anastomosis. In three patients (4%) proctocolectomy with terminal il- eostomy was performed. Early and late complication rate were similar (22.7% × 24%). Ileal pouch surgery exhibited tendency to a higher morbidity and mortality but no significance could be found. Overall mortality rate was 7.46%. Malignant neoplasia was the main cause of mortality, accounting for 60% of deaths.ConclusionFAP is a rare pathology in our country. Genetic counseling and proper screening programs are essential tools to early diagnosis and follow-up. Surgery is the most effective treatment and the best option to prevent malignant neoplasia

Association between celiac disease and Crohn's disease - a challenge to the coloproctologist

Over the past few years, many studies on the association between celiac disease and inflammatory bowel disease have been reported. The genetic origin of this association has prompted research that searches for a common link for the concomitant manifestation of these pathologies. Clinical studies aim not only to demonstrate this relation, but also to establish the epidemiological frequencies among affected individuals and their relatives as compared to the general population. The similar clinical symptoms, difficulties, diagnoses, and therapeutics are still a challenge, since this association is unknown to most coloproctologists, thereby culminating in treatments and surgical procedures with no benefits for the patient.Nos últimos anos, muitos estudos foram relatados sobre a associação entre a doença celíaca e as doenças inflamatórias intestinais. A origem genética dessa associação desperta pesquisas que buscam o elo comum para a manifestação concomitante das patologias. Estudos clínicos visam não apenas demonstrar essa relação mas também estabelecer as frequências epidemiológicas entre os indivíduos acometidos e seus familiares em relação à população geral. À semelhança do quadro clínico, as dificuldades diagnósticas e terapêuticas são ainda desafios, já que tal associação ainda é desconhecida para a maioria dos coloproctologistas, podendo resultar em tratamentos e cirurgias sem benefícios ao paciente

Proctocolectomy and ileal J-pouch anal anastomosis on the surgical treatment of familial adenomatous polyposis and ulcerative colitis: analysis of 49 cases

OBJECTIVE: To evaluate the results of ileal J-pouch anal anastomosis in ulcerative colitis and familial adenomatous polyposis. METHOD: Retrospective analysis of medical records of 49 patients submitted to ileal J-pouch anal anastomosis. RESULTS: Ulcerative colitis was diagnosed in 65% and familial adenomatous polyposis in 34%. Mean age was 39.5 years. 43% were male. Among familial adenomatous polyposis, 61% were diagnosed with colorectal cancer. Thirty-one percent of patients with ulcerative colitis was submitted to a previous surgical approach and 21% of these had toxic megacolon. Average hospital stay was 10 days. Post-operative complications occurred in 50% of patients with ulcerative colitis and 29.4% with familial adenomatous polyposis. Intestinal diversion was performed in 100% of ulcerative colitis and 88% of familial adenomatous polyposis. Pouchitis occurred in eight cases (seven ulcerative colitis and one FAP), requiring excision of the pouch in three ulcerative colitis. Mortality rate was 7.6%: two cases of carcinoma on the pouch and two post-operative complications. Late post-operative complications occurred in 22.4%: six familial adenomatous polyposis and five ulcerative colitis). Two patients had erectile dysfunction, and one retrograde ejaculation. One patient with severe perineal dermatitis was submitted to excision of the pouch. Incontinence occurred in four patients and two reported soil. Mean bowel movement was five times a day. CONCLUSION: Ileal J-pouch anal anastomosis is a safe surgery with acceptable morbidity and good functional results, if well indicated and performed in referral centers

Estudo da formação de aderências e da cicatrização de anastomoses colônicas em ratos com sepse peritoneal induzida

OBJETIVO: Avaliar os efeitos da sepse abdominal sobre a formação de aderências e a cicatrização de anastomoses colônicas em ratos. MÉTODOS: 40 ratos distribuídos em dois grupos contendo 20 animais, para anastomose do cólon esquerdo na presença (grupo S) ou ausência (grupo N) de indução de sepse por ligadura e punção do ceco (CLP). Cada grupo foi dividido em subgrupos para eutanásia no terceiro (N3 e S3) ou sétimo (N7 e S7) dia de pós-operatório (DPO). Foi avaliada a quantidade de aderências e removido um segmento colônico contendo a anastomose para análise histopatológica, força de ruptura, hidroxiprolina e conteúdo de colágeno tecidual. RESULTADOS: Os animais submetidos à CLP apresentaram maior quantidade de aderências intra-abdominais tanto no 3° DPO (p=0,00) quanto no 7° DPO (p=0,00). Tiveram menores valores de força de ruptura no 3° DPO (p=0,00), porém maiores valores no 7° DPO (p=0,00). Não houve diferença na variação da concentração de hidroxiprolina, conteúdo de colágeno e histopatologia. CONCLUSÕES: A infecção peritoneal desencadeada por CLP aumentou a quantidade de aderências intra-cavitárias. Houve diminuição da resistência de anastomoses cólicas no 3° DPO, com posterior aumento no 7° DPO, sem efeito sobre os outros parâmetros da cicatrização. ________________________________________________________________________________ ABSTRACTPURPOSE: To evaluate the effects of abdominal sepsis on adhesion formation and colon anastomosis healing in rats. METHODS: Forty rats were distributed in two groups containing 20 rats each for left colon anastomosis in the presence (Group S) or absence (Group N) of induced sepsis by cecal ligation and puncture. Each group was divided into subgroups for euthanasia on the third (N3 and S3) or seventh (N7 or S7) post-operative day. The amount of adhesions was evaluated and a segment of the colon was removed for histopathologic analysis, bursting strength assessment, hydroxyproline and the determination of tissue collagen. RESULTS: The subjects which underwent cecal ligation and puncture presented a higher amount of intra-abdominal adherences in both third (p=0,00) and seventh (p=0,00) post-operatory days. Smaller bursting strengths were found in the S3 subgroup, and greater bursting strengths were found in the S7 subgroup. There was no difference in the variations on the concentrations of hydroxyproline, tissue collagen and histopathology. CONCLUSIONS: The peritoneal infection which was developed by cecal ligation and puncture raised the amount of intra-cavitary adhesions. There was a decrease in the amount of colonic anastomosis on the third post-operatory day with a following raise on the seventh without any effects on other healing parameters

Hyperbaric oxygen therapy and inflammatory bowel disease

La enfermedad inflamatoria intestinal (EII), incluida la colitis ulcerosa (CU) y la enfermedad de Crohn (EC), es un grupo de enfermedades crónicas recurrentes caracterizadas por una inflamación crónica del tracto gastrointestinal. La prevalencia de la EII está aumentando a nivel mundial y, en las últimas décadas, se lograron mejoras significativas en las opciones terapéuticas que han reducido la necesidad de hospitalización y cirugía. Sin embargo, incluso con estrategias de tratamiento médico óptimas, los pacientes con EC pueden experimentar progresión de la enfermedad con complicaciones perianales, intestinales y extraintestinales. Además, una cuarta parte de los pacientes con CU desarrollará una exacerbación aguda grave de la enfermedad durante su vida. A pesar de las altas dosis de corticosteroides, la mitad de estos pacientes fracasará en la terapia de rescate médico posterior y la otra mitad necesitará colectomía dentro de los 5 años.  El propósito de esta revisión es resumir la función de TOHB en el tratamiento de la EII

Chronic idiopathic intestinal pseudo-obstruction treated with jejunostomy: case report and literature review

CONTEXT: Chronic idiopathic intestinal pseudo-obstruction is a very rare condition. CASE REPORT: This study describes a male patient who had presented obstructive symptoms for 24 years. He had been treated clinically and had undergone two previous operations in different services, with no clinical improvement or correct diagnosis. He was diagnosed with intestinal obstruction without mechanical factors in our service and underwent jejunostomy, which had a significant decompressive effect. The patient was able to gain weight and presented improvements in laboratory tests. Jejunostomy is a relatively simple surgical procedure that is considered palliative but, in this case, it was resolutive
