RESUMO Objetivo: Este estudo teve como objetivo avaliar a prevalência de algumas comorbidades epidemiologicamente importantes em pacientes com megaesôfago chagásico em relação à população sem o megaesôfago e se essa condição seria um fator protetor ou de risco para as condições analisadas. Métodos: Este estudo descritivo observacional coletou dados de prontuários de pacientes com diagnóstico prévio de megaesôfago (período: de 2005 a 2020). Os pacientes foram divididos por idade em um grupo geral (todas as idades) e um grupo idoso (60 anos ou mais). Foram pesquisadas associações para quatro áreas/sistemas/envolvimentos principais: cardiovascular, respiratório, endócrino e neurológico. Resultados: O grupo geral incluiu 546 pacientes e o grupo idosos incluiu 248 pacientes. Quanto à prevalência de comorbidades no grupo geral, as três doenças mais prevalentes foram hipertensão, com 44,3% (IC95%: 40,21-48,51%); dislipidemia, com 17,8% (IC95%: 14,79-21,19%); e insuficiência cardíaca, com 15,2% (IC95%: 12,43-18,45%). Assim como no grupo geral, as comorbidades mais prevalentes no grupo de idosos foram hipertensão, dislipidemia e insuficiência cardíaca. Conclusão: Hipertensão arterial sistêmica, dislipidemia e insuficiência cardíaca foram as comorbidades mais prevalentes nessa população. A menor prevalência de diabetes mellitus e doença de Alzheimer sugere uma associação de denervação do sistema nervoso entérico e requer mais investigação.

ABSTRACT Objective: This study aimed to evaluate the prevalence of some epidemiologically important comorbidities in patients with Chagas megaoesophagus in relation to the population without megaoesophagus, and whether this condition would be a protective or a risk factor for the conditions analysed. Methods: This observational descriptive study collected data from the medical records of patients with a previous diagnosis of megaoesophagus (timing: from 2005 to 2020). The patients were divided by age into a general (all ages) and an older group (aged 60 years or more). Associations were searched for four main areas/systems/involvements: cardiovascular, respiratory, endocrine and neurological. Results: The general group included 546 patients and the older group included 248 patients. As for the prevalence of comorbidities in the general group, the three most prevalent diseases were hypertension, with 44.3% (CI95%: 40.21-48.51%); dyslipidaemia, with 17.8% (CI95%: 14.79-21.19%); and heart failure, with 15.2% (CI95%: 12.43-18.45%). Similar to that in the general group, the most prevalent comorbidities in the group of older patients were hypertension, dyslipidaemia, and heart failure. Conclusion: Systemic arterial hypertension, dyslipidaemia, and heart failure were the most prevalent comorbidities in this population. The lower prevalence of diabetes mellitus and Alzheimer’s disease suggests the association of enteric nervous system denervation and requires further investigation.

Abstract Purpose To analyze the resistance to medial traction of abdominal wall muscles, before and after performing relaxing incisions. Methods Seventeen live pigs were used. After a median laparotomy, the handles were made in the rectus abdominis muscles (RAM) to fit the dynamometer. Step 1 (control phase): tensile strength measured without performing relaxant incisions. Step 2: A curvilinear relaxant incision was made on the anterior blade of the right RAM sheath and then the tensile strength was measured by the edge of the wound. The same procedure was adopted after incision of the left posterior blade. Step 3: Relaxing incisions were made in the right posterior and left anterior blade, so that both sides were left with a relaxing incision on both blades. Measurements of resistance were performed. Results There was no statistically significant difference between the sides. On the right and left side, all treatments reduced the tensile strength when compared to each other and to the control. There was a reduction of 12% and 9.8% after incision of the anterior and posterior blade, respectively. Conclusion Relaxing incisions reduced tensile strength in the ventral abdominal wall.

ABSTRACT Purpose The study aims to assess the influence of the stage of chronic kidney disease and glomerular filtration rate on prevalence and degree of erectile dysfunction. Materials and Methods This transversal study, conducted from May 2013 to December 2015, included patients with chronic kidney disease in conservative treatment, stages III/IV/V. Erectile dysfunction was evaluated by the International Index of Erectile Function. Data classically associated with erectile dysfunction were obtained by medical record review. Erectile dysfunction, degree of erectile dysfunction, and other main variables associated with erectile dysfunction were compared between patients with chronic kidney disease on conservative treatment stages III versus IV/V using the Chi-square test. The relationship between score of the International Index of Erectile Dysfunction and glomerular filtration rate was established by Pearson correlation coefficient. Results Two hundred and forty five patients with chronic kidney disease in conservative treatment participated of the study. The prevalence of erectile dysfunction in patients with chronic kidney disease in stages IV/V was greater than in stage III. Glomerular filtration rate positively correlated with score of the International Index of Erectile Dysfunction. Conclusions The study suggests that chronic kidney disease progression (glomerular filtration rate decrease and advance in chronic kidney disease stages) worsen erectile function. Hypothetically, diagnosis and treatment of erectile dysfunction may be anticipated with the analysis of chronic kidney disease progression.

Transmission of Trypanosoma cruziduring pregnancy is estimated to occur in less than 20% of infected mothers; however, the etiopathogenesis is not completely understood. The Centre for Studies on Chagas Disease provides confirmation of T. cruziinfection for individuals living in central Brazil. In this retrospective hospital-based study, all requests for diagnosis of T. cruziinfection in individuals less than 21 years old from 1994-2014 were searched. We end with 1,211 individuals and their respective infected mothers. Congenital transmission of infection was confirmed in 24 individuals (2%) in central Brazil, an area where the main T. cruzi lineage circulating in humans is TcII. This low prevalence of congenital Chagas disease is discussed in relation to recent findings in the south region of Brazil, where TcV is the main lineage and congenital transmission has a higher prevalence (approximately 5%), similar to frequencies reported in Argentina, Paraguay and Bolivia. This is the first report to show geographical differences in the rates of congenital transmission of T. cruziand the relationship between the prevalence of congenital transmission and the type of Tc prevalent in each region.

OBJETIVO: analisar os aspectos clinicos e patológicos de pacientes operados de cancer colorretal diagnosticados durante operações abdominais de urgencia. MÉTODOS: foram estudados os prontuários de 107 pacientes operados entre 2006 e 2010. Resultados: Foram incluidos 58 mulheres e 49 homens com idade media de 59,8 anos. Os sintomas mais frequentes foram: dor abdominal (97,2%), parade de eliminação de gases e fezes (81,3%), vomitos (76,6%) e anorexia (40,2%). Os pacientes foram divididos em cinco grupos: abdomen agudo obstrutivo (68), abdomen agudo perfurativo (21), abdomen agudo inflamatorio (13), sepsis abdominal (3) e hemorragia digestive baixa (2). Os tumores localizavam-se no rectossigmoide (51,4%), colon transverso (19,6%), colon ascendente (12,1%), colon descendente (11,2%) e 5,6% dos pacientes apresentavam tumors sincronicos. O tratamento cirurgico foi: colectomia com colostomy (85%), colectomia com anastomose primaria (10,3%) e colostomia sem ressecçao do tumor (4,7%). Mortalidade immediate ocorreu em 33,4% dos pacientes. Analise bivariate de sexo, localização do tumor e estadio não foi relacionada a mortalidade (P>0,05%). CONCLUSÕES: o cancer colorretal pode ser a causa de obstrução colonica ou perfuração in pacientes com queixas inespecificas. A despeito da alta taxa de mortalidade, a ressecção do tumor pode ser realizada na maioria dos pacientes.

OBJECTIVE: to report clinical and pathological features of patients with colorectal cancer diagnosed during emergency abdominal surgery. METHODS: records of 107 patients operated between 2006 and 2010 were reviewed. RESULTS: there were 58 women and 49 men with mean age of 59.8 years. The most frequent symptoms were: abdominal pain (97.2%), no bowel movements (81.3%), vomiting (76.6%), and anorexia (40.2%). Patients were divided into five groups: obstructive acute abdomen (n = 68), obstructive acute perforation (n = 21), obstructive acute inflammation (n = 13), abdominal sepsis (n = 3), and severe gastrointestinal bleeding (n = 2). Tumors were located in the rectosigmoid (51.4%), transverse colon (19.6%), ascendent colon (12.1%), descendent colon (11.2%), and 5.6% of the cases presented association of two colon tumors (synchronic tumors). The surgical treatment was: tumor resection with colostomy (85%), tumor resection with primary anastomosis (10.3%), and colostomy without tumor resection (4.7%). Immediate mortality occurred in 33.4% of the patients. Bivariate analysis of sex, tumor location and stage showed no relation to death (p > 0.05%). CONCLUSIONS: colorectal cancer may be the cause of colon obstruction or perfuration in patients with nonspecific colonic complaints. Despite the high mortality rate, resection of tumor is feasible in most patients.

Purpose: The proposal of this study was to determine the prevalence and the associated factors of erectile dysfunction (ED) among hemodialysis (HD) patients. Materials and Methods: This was a cross-sectional study based on data collected from HD male patients. Clinical, demographic and laboratory data of all patients were collected in three HD clinics from December 2010 to June 2011. Patients answered questions of erectile function domain from International Index of Erectile Function. Data were evaluated by descriptive analysis and by univariate (ULRA) and multivariate logistic regression analysis (MLRA). Results: Three hundred and five patients participated of the study. The prevalence of ED was 68.19%. ED was associated with diabetes (DM), benign prostatic hyperplasia, glomerulonephritis as cause of chronic renal failure (CRF), smoking habits, lower creatinine levels (ULRA), use of calcium channel blocker (MLRA), aging, lower education level, alcohol consumption, DM (as cause of CRF) and coronary insufficiency (ULRA and MLRA). Conclusions: ED was highly prevalent in the HD men. It was independently associated with aging, current use of alcohol, long alcohol use (even for those who do not drink more), lower education level, diabetes as cause of CRF, coronary insufficiency and use of channel blockers calcium.

ContextoA síndrome do intestino irritável (SII) é uma doença funcional do intestino, caracterizada por dor abdominal e alterações do hábito intestinal, cuja fisiopatologia permanece desconhecida. Estudos recentes sustentam a hipótese de que algumas formas de SII, especialmente a síndrome do intestino irritável tipo diarreia (SII-D), apresentam sinais de uma inflamação de baixo grau persistente da mucosa intestinal e alterações da microflora intestinal. A mesalazina é conhecida por suas propriedades anti-inflamatórias intestinais. OSaccharomyces boulardii é um probiótico largamente utilizado para o tratamento da diarreia relacionada à causa infecciosa.ObjetivoAvaliar os efeitos da mesalazina, da terapia com mesalazina combinada ao Saccharomyces boulardii e doSaccharomyces boulardii, em pacientes com SII-D.MétodoCom base nos critérios de Roma III, 53 pacientes com SII-D (maiores de 18 anos) foram incluídos. Para excluir as doenças orgânicas, todos os pacientes realizaram colonoscopia, coprocultura, anticorpo anti-endomísio, teste de tolerância à lactose e exame parasitológico de fezes. Os pacientes foram divididos em três grupos: grupo mesalazina (GM) – 20 pacientes foram medicados com mesalazina via oral 800 mg t.i.d. por 30 dias; grupo mesalazina e Saccharomyces boulardii (GMSb) – 21 pacientes foram medicados com mesalazina 800mg t.i.d. eSaccharomyces boulardii 200 mg via oral t.i.d. por 30 dias; grupo Saccharomyces boulardii (GSb) – 12 pacientes foram medicados com Saccharomyces boulardii200 mg t.i.d. por 30 dias. Não foram permitidas drogas concomitantes com algum efeito sobre secreção ou motilidade intestinal. Os sintomas foram avaliados no basal e após tratamento por meio da escala de Likert de 4 pontos que incluía: frequência de evacuações; forma e consistência das fezes (baseado na escala de Bristol); dor abdominal; e distensão abdominal. A analise estatística foi realizada por meio de testet pareado e do teste de Kruskal-Wallis.ResultadosComparados ao basal, observou-se uma redução estatisticamente significativa da pontuação de sintomas após 30 dias de tratamento no GM (P<0.0001); GMSb (P<0.0001); e GSb (P<0.003). Diferença estatisticamente significativa da pontuação de sintomas após 30 dias de tratamento entre GM, GMSb e GSb (P = 0.03). Não foi observada diferença estatisticamente significativa entre GM e GMSb após 30 dias de tratamento (P = 0,9).ConclusãoO uso da mesalazina isolada, do Saccharomyces boulardii isolado ou do tratamento combinado com ambos, mesalazina e Saccaromyces boulardii, melhoraram os sintomas da SII-D. A melhora dos sintomas foi maior naqueles que usaram mesalazina seja isolada ou em combinação com Saccharomyces boulardii quando comparada com o uso de Saccharomyces boulardii isoladamente. Estes resultados sugerem que a mesalazina pode ser útil no tratamento de pacientes com SII-D e justificam outros estudos com maior número de pacientes.

ContextIrritable bowel syndrome (IBS) is a functional bowel disease characterized by abdominal pain and altered intestinal habits. The pathophysiology of IBS remains unclear. Recent studies have demonstrated that some IBS patients, especially in diarrhea-predominant IBS (IBS-D), display persistent signs of minor mucosal inflammation and a modified intestinal microflora. The mesalazine has known intestinal anti-inflammatory properties. Saccharomyces boulardii is a probiotic used for a long time in treatment of diarrhea, including infectious diarrhea.ObjectiveEvaluate the effects of mesalazine alone, combined therapy of mesalazine with liophylised Saccharomyces boulardii or alone on symptoms of IBS-D patients.MethodsBased on Rome III criteria, 53 IBS-D patients (18 year or more) were included. To exclude organic diseases all patients underwent colonoscopy, stool culture, serum anti-endomisium antibody, lactose tolerance test and ova and parasite exam. Patients were divided in three groups: mesalazine group (MG) - 20 patients received mesalazine 800 mg t.i.d. for 30 days; mesalazine and Saccharomyces boulardii group (MSbG) - 21 patients received mesalazine 800 mg t.i.d. and Saccharomyces boulardii 200 mg t.i.d. for 30 days and; Saccharomyces boulardii group (SbG) – 12 patients received Sb 200 mg t.i.d. for 30 days. Drugs that might have any effect on intestinal motility or secretion were not allowed. Symptom evaluations at baseline and after treatment were performed by means of a 4-point likert scale including: stool frequency, stool form and consistency (Bristol scale), abdominal pain and distension. Paired t test and Kruskal-Wallis test were used for statistical analyses.ResultsCompared to baseline, there were statistically significant reduction of symptom score after 30 th day therapy in all three groups: MG (P<0.0001); MSbG (P<0.0001) and in SbG (P= 0.003). There were statistically significant differences in the symptom score at 30 th day therapy of the MG, MSbG and SbG groups (P = 0.03). There were no statistical differences between MSbG and MG symptom score at 30th day therapy (P = 0.9).ConclusionsThe use of mesalazine alone, Saccharomyces boulardii alone or combined treatment with mesalasine andSaccaromyces boulardii improved IBS-D symptoms. The improvement of the symptom score was greater with mesalazine alone or combined with Sb as compared with Sb treatment alone. These preliminary results suggest that mezalazine may be useful in treatment of IBS-d patients, and warrant further larger studies.

Introduction Chagasic megaesophagus (CM) is the most common digestive manifestation of Chagas disease in Brazil, and the State of Goiás is one of the most affected regions. In recent decades, the Hospital das Clínicas (HC)/Universidade Federal de Goiás (UFG) has been a reference center for the study and treatment of CM. The objective of this study was to characterize the current epidemiological profile of patients with CM observed at the HC of the UFG from 1998 to 2010. Methods In total, 939 patient records were analyzed, and age, gender, place of birth, serology, symptoms and radiological classification according to Rezende et al. were analyzed. Results The median patient age was 55 years. Male patients were more (54%) prevalent than female patients. The prevalence of younger patients (less than 31 years of age) was 4.2%, but 82.1% of the younger patients were from State of Bahia. Patients older than 40 years were the majority (85.5%). The radiological groups were distributed as follows: Group I (35.9%), Group II (32.9%), Group III (17%) and Group IV (14.2%). Conclusions Compared with previous studies by the same group in 1975, 1994 and 1995, the number of younger patients decreased, and the frequency curve has shifted to older patients.

OBJETIVO: Avaliar a função pulmonar pós-colecistectomias laparoscópicas. MÉTODOS: Estudo prospectivo, onde se avaliaram espirometrias pós-operatórias de 15 pacientes submetidas à colecistectomias laparoscópicas por meio de um tempo anestésico-cirúrgico abreviado. Os dados pós-operatórios foram comparados aos pré-operatórios RESULTADOS: Existiram diferenças significativas para as variáveis Capacidade Vital Forçada (p=0,020) e Volume Expiratório Forçado no 1º segundo (p=0,022) no pré e pós-operatório imediato, indicando distúrbios ventilatórios restritivos. CONCLUSÃO: Foram observados distúrbios ventilatórios restritivos leves pós-colecistectomias laparoscópicas, com rápida recuperação da função pulmonar, o que pode diminuir a morbidade pulmonar pós-operatória.

OBJECTIVE: To evaluate pulmonary function after laparoscopic cholecystectomies. MEHTODS: Prospective study, in which the post-operative spirometries of 15 patients who underwent laparoscopic cholecystectomies with abbreviated anesthetic-surgical time were analyzed. RESULTS: Significant differences existed for the Forced Vital Capacity variable (p=0,020) and Forced Expiratory Volume in the first second (p=0,022) between pre- and immediate post-operative, indicating restrictive ventilatory disturbances. CONLCUSION: Light restrictive laparoscopic post-cholecystectomy ventilatory disturbances were observed, with rapid recovery of pulmonary function, which may lower post-operative pulmonary morbidity.

OBJETIVO: Avaliar a função pulmonar pós-colecistectomias subcostais abertas de pacientes sob ação da morfina no pós-operatório imediato. MÉTODOS: Tratou-se de um estudo prospectivo, onde se avaliaram espirometrias pós-operatórias de 15 pacientes submetidas à colecistectomias abertas subcostais, que receberam dose única de morfina peridural na anestesia. Os dados pós-operatórios foram comparados aos pré-operatórios pelo teste t-Student emparelhado. Um valor de p < 0,05 foi considerado estatisticamente significativo. RESULTADOS: Existiram diferenças significativas para as variáveis Capacidade Vital Forçada (p = 0,007) e Volume Expiratório Forçado no 1º segundo (p = 0,008) no pré e pós-operatório imediato, indicando distúrbios ventilatórios restritivos. Todas as pacientes apresentaram espirometrias normais no 3º dia de pós-operatório. CONCLUSÃO: Mesmo sob ação analgesia da morfina peridural, no pós-operatória imediato, foram observados distúrbios ventilatórios restritivos leves pós-colecistectomias subcostais abertas. Contudo, observou-se uma rápida recuperação da função pulmonar, o que pode diminuir a morbidade pulmonar pós-operatória.

OBJECTIVE: To evaluate pulmonary function after open subcostal cholecystecomy under action of the morphine in the immediate post-operative. METHODS: This was a prospective study, in which the post-operative spirometries of fifteen patients who underwent open subcostal cholecystectomies which received peridural morphine anesthesia. Post- and pre-operative data were compared using a paired student-t test. A value of p < 0,05 was considered statistically significant. RESULTS: Significant differences existed for the Forced Vital Capacity variable (p = 0,007) and Forced Expiratory Volume in the first second (p = 0,008) between pre- and immediate post-operative, indicating restrictive ventilatory disturbances. All of the patients presented normal espirometries in the third day of post-operative. CONCLUSION: Even under action morphine peridural analgesia, in the immediate post-operative, light restrictive post-cholecystectomy ventilatory disturbances were observed. However, it was observed abbreviated recovery of pulmonary function, which may lower post-operative pulmonary morbidity.

INTRODUÇÃO: Operações, principalmente de abdome superior, cursam no pós-operatório com hipoxemia e distúrbios ventilatórios restritivos. O objetivos da presente revisão foram: a) fazer retrospecto histórico das técnicas espirométricas e da avaliação laboratorial da hipoxemia, por meio da pressão arterial de oxigênio (PaO2) e, b) rever os principais fatores responsáveis pelas alterações da função pulmonar pós-operatória. MÉTODOS: Fez-se revisão histórica sobre os principais aspectos espirométricos e da medida da PaO2, correlacionando esses exames como aferidores da função pulmonar, após operações abdominais. CONCLUSÕES: Operações em andar superior do abdome podem cursar com hipoxemia e distúrbios ventilatórios restritivos, cuja principal causa é a disfunção diafragmática, que pode ser minimizada por meio de laparoscopia e um eficaz tratamento da dor pós-operatória.

INTRODUCTION: Operations, particularly those of the upper abdomen, can be accompanied by hypoxemia and restrictive ventilatory disturbances. The objectives of the present review were: a) to provide a retrospective of spirometric techniques and laboratory assessment of hypoxemia by means of arterial oxygen pressure; b) to review the main factors responsible for alterations in postoperative pulmonary function. METHODS: A historical overview is given of the main aspects of spirometry and PaO2, measurement, considering these exams as measures of pulmonary function after abdominal operations. CONCLUSION: Operations on the upper part of the abdomen may be followed by hypoxemia and restrictive ventilatory disturbances, whose principal cause is diaphragmatic dysfunction which can be minimized by means of laparoscopy and effective post-operative pain treatment.

OBJETIVO: Avaliar a função pulmonar pós-colecistectomias laparoscópicas e subcostais abertas. MÉTODOS: Tratou-se de um ensaio randomizado, onde se avaliaram espirometrias pós-operatórias de dois grupos, cada qual com 15 pacientes. O grupo GL foi submetido a colecistectomia laparoscópica. O grupo GA foi submetido a colecistectomia por via subcostal, por meio de mini-laparotomia e abreviado tempo anestésico-cirúrgico. As variáveis dos dois grupos foram comparadas entre si por meio da ANOVA. Entre um mesmo grupo, antes e depois das operações, utlizou-se do teste t-Student emparelhado. Um valor de p < 0,05 foi considerado estatisticamente significativo. RESULTADOS: Todas as pacientes, dos dois grupos, apresentaram distúrbios ventilatórios restritivos pós-operatórios, com normalização espirométrica mais rápida nas pacientes operadas por laparoscopia. Grupos GL X GA, no pós-operatório imediato: Capacidade vital forçada (p < 0,001) e Volume Expiratório forçado em 1 segundo (p < 0,001). CONCLUSÕES: O prejuízo pós-operatório da função pulmonar foi significativamente menor nas colecistectomias laparoscópicas do que nas abertas, mesmo por meio de mini-laparotomia e abreviado tempo anestésico-cirúrgico.

BACKGROUND: To evaluate pulmonary function after laparoscopic and subcostal cholecystectomies. METHODS: This was a randomized study, in which postoperative spirometries in two groups of fifteen patients each were evaluated. Group GL underwent laparoscopic chlecystectomies. Group GA underwent open subcostal cholecystectomies by means of mini-laparatomy, in abbreviated anesthetic-surgical time. The two groups´ variables were compared using ANOVA. Within the same group, before and after the operations, the paired Student-t test was used. A value of p < 0.05 was considered statistically significant. RESULTS: All patients from both groups presented restrictive postoperative ventilatory disturbances, with a faster spirometric normalization for those patients operated through laparoscopy. Groups GL vs. GA, in immediate post-operative: Forced Vital Capacity (p < 0.001) and Forced Expiratory Volume in one second (p < 0.001). CONCLUSION: Postoperative harm to pulmonary function was significantly less in laparoscopic than in open cholecystectomies, even with mini-laparotomies and abbreviated anesthetic-surgical time.

Pacientes com megaesôfago (ME) possuem incidência aumentada de câncer de esôfago. Em contraste, há poucos relatos na literatura de associação entre megacólon (MC) e câncer de cólon. O MC é muito comum em algumas regiões do Brasil, e na maioria das vezes, está associado à Doença de Chagas. Nós reavaliamos os arquivos de patologia de peças cirúrgicas de todos os pacientes submetidos à ressecção de MC no Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto (HC-FMRP), da Universidade de São Paulo. Encontramos o número de 894 pacientes que foram operados de 1952 até 2001 para a ressecção do MC. Úlceras da mucosa, hiperplasia e inflamação crônica foram frequentemente encontrados, enquanto pólipos foram incomuns. Nenhum paciente com MC apresentou qualquer tipo de neoplasia do cólon. Essa observação reforça a hipótese de que o MC tem uma associação negativa com câncer de cólon. Isso parece contradizer o conceito tradicional de carcinogênese do cólon, uma vez que pacientes com MC apresentam constipação crônica importante, a qual é tida como uma causa que aumenta o risco de câncer de cólon. MC também está associado a outros fatores de risco para o câncer de cólon, como hiperplasia, úlceras da mucosa e inflamação crônica. No megaesôfago (ME), tais fatores aumentam o risco de câncer esofágico. O estudo da proliferação celular da mucosa no MC pode fornecer informações úteis sobre o papel da constipação na carcinogênese colônica.

Patients with megaesophagus (ME) have increased prevalence of cancer of the esophagus. In contrast, a higher incidence of colorectal cancer is not observed in patients with megacolon (MC). MC is very common in some regions of Brazil, where it is mainly associated with Chagas disease. We reviewed the pathology records of surgical specimens of all patients submitted for surgical resection of MC in the Hospital das Clínicas of the Faculty of Medicine of Ribeirão Preto (HC-FMRP), from the University of São Paulo. We found that 894 patients were operated from 1952 until 2001 for MC resection. Mucosal ulcers, hyperplasia and chronic inflammation were frequently found, while polyps were uncommon. No patients with MC presented any type of colonic neoplasm. This observation reinforces the hypothesis that MC has a negative association with cancer of the colon. This seems to contradict the traditional concept of carcinogenesis in the colon, since patients with MC presents important chronic constipation that is thought to cause an increase in risk for colon cancer. MC is also associated with other risk factors for cancer of colon, such as hyperplasia, mucosal ulcers and chronic inflammation. In ME these factors lead to a remarkable increase in cancer risk. The study of mucosal cell proliferation in MC may provide new insights and useful information about the role of constipation in colonic carcinogenesis.
