Colonoscopic findings in patients aged 50 years and older: a critical analysis of 1614 exams

Abstract

Introduction Colonoscopy has shown to be useful in the diagnosis of various pathologies. By allowing the direct visualization of the mucosa, colonoscopy allows the adoption of therapeutic methods, such as the removal of polyps, dilation of stenoses, and biopsies. This method can also be applied in the detection of colorectal cancer, which currently represents an important cause of mortality in the world. Individuals considered to be at medium risk for the development of colorectal cancer should start screening at 50 years of age in order to detect early disease. Objective To describe the main results of the exams for patients at least 50 years old who underwent colonoscopy. Method Descriptive, case-series study of 1614 colonoscopies performed from 2014 to 2017 at a referral hospital in Salvador, Bahia. Results The main indications for the study were intestinal bleeding (26.5%), neoplasia screening (20.7%), and abdominal pain (10.2%). The main results were diverticular disease (38.9%), polyps (38.8%), and normal examination (23.2%). Patients with indications for neoplasia screening had the presence of polyps (41.3%) as their main diagnosis. For patients with normal examination, 28.8% presented intestinal bleeding as an indication. There were 70 (4.3%) patients with a colonoscopic diagnosis of neoplasia. Conclusion The present study, which demonstrated a majority of exams with considerable alterations, shows the usefulness of the examination, besides other advantages, as a form of diagnosis of colorectal cancer.

Colonoscopic and Histopathological Findings in Patients with Various Lower Gastrointestinal Symptoms: A Single-Center Experience

“…It is believed that the incidence of diarrhea, regardless of the diagnosis, is higher among males (17) . It is well established that increasing age is correlated to increasing risk of malignancy (18) . That was confirmed by our findings, as age was found to be a significant predictor of malignancy and NSCC as well.…”

Prevalência de lesões de cólon diagnosticadas pela videocolonoscopia no período de 2019 a 2021

“…A maioria dos indivíduos submetidos à colonoscopia foram do sexo feminino, dado semelhante ao encontrado na literatura (Leal et al, 2019). Do ponto de vista cultural, é mais comum que as mulheres busquem assistência médica em comparação aos homens, que tendem a ser mais relutantes em relação a procedimentos como colonoscopia e retossigmoidoscopia.…”

“…Os resultados mais significativos incluíram a detecção de pólipos e doença diverticular, resultados que se assemelham aos achados de um estudo conduzido em um hospital de referência no estado da Bahia (Leal et al, 2019). Além disso, ambas as pesquisas revelaram taxas semelhantes de achados endoscópicos normais.…”

Numerical analysis of multiscale methods for elliptic-parabolic problems with application in the cell dynamics during the formation of colorectal cancer

“…Colonoscopy examination allows early identification of lesions, signs and symptoms, and allows biopsies to be performed. In (MENDES et al, 2018), they present some indicators and findings for the exam in patients aged ą 50 years who underwent colonoscopy (n " 1.614 exams): Source: (MENDES et al, 2018) We can verify from Table 1 and Table 2 that colonoscopy is an important exam for the diagnosis of various colorectal diseases including the first stages of CRC. In general the current treatment options for CRC are surgery, chemotherapy, and biological therapies (SOCIETY, 2018b).…”
