Diagnostic performance of ultrasound without any colon preparation for detecting colorectal polyps in pediatric patients

ConclusionThe accuracy for detecting colorectal polyps by ultrasound was 89% (95% CI, 80 –95%) in our cohort. Polyps found in the rectum and relatively smaller polyps accounted for several false-negative cases.

ConclusionOsseous metaplasia of the gastrointestinal tract is a rare occurrence that can be associated with benign polyps or malignancy. Certain markers have been shown to be linked to this process and polypectomy remains the gold standard of treatment; however, further research is warranted.

Rationale: Adenocarcinoma coexists with adjacent microscopic gastrointestinal stromal tumor (micro-GIST) is rare, especially in the rectum, where the gastrointestinal stromal tumors (GISTs) have the lower incidence rate. It is easy to ignore the concurrent micro-GIST due to the untypical symptoms. Patient concerns: A 77-year-old male patient suffered from lower abdominal pain for 20 days and presented with per rectal bleeding for 10 days. He had the medical history of hypertension and diabetes for more than 25 years. Diagnoses: Endoscopy revealed that the patient had rectum adenocarcinoma and multiple rectum polyps...

This study was carried out in accordance with approval of the Melbourne Health and Walter and Eliza Hall Institute of Medical Research's Human Research Ethics Committee (approval number: 2013.081). All subjects gave written informed consent for participation and publication. Results and Discussion TGF-β signaling in NK cells is associated with: phosphorylation in SMAD2 and 3, inhibition of IL-15-induced metabolism/proliferation, simultaneous downregulation of CD44, CD49e, and Eomes, and upregulation of CD16 and CD49a expression (7, 10). SMAD family member 4 (SMAD4) belongs to the SMAD family of transcription...

CONCLUSION: Also in our experience adenomatous polyps play a crucial role in the development of colorectal cancer. Therefore, it seems quite essential to avert colorectal cancers gradually. Colonoscopy is a non-invasive method of diagnosis and a treatment of colorectal polyps. Proper and careful colonoscopy examination is indispensable in the discovery of colorectal polyps and subsequent follow-up. Timely and routine colonoscopy is considered as an important approach for thwarting the development of malignant neoplasms.

ConclusionA review of the literature shows that cap polyposis can occur at any age, including childhood, with a slight predilection for the male gender. Rectal bleeding and rectal polyps are consistent features in all reported cases. Other typical symptoms include constipation, diarrhea, and abdominal pain. Symptoms may be very similar to those of chronic inflammatory bowel disease, the most important differential diagnosis. The cause of cap polyposis is still unclear, and specific therapy has not as yet been established. Conservative therapeutic measures should be preferred, especially in children.

​BY ARJUN BHARADWAJ; MARGARET GAVOR, MBChB, MPH; &KHALID MALIK, MDA 65-year-old man presented to the emergency department complaining of sudden-onset left-sided abdominal pain followed by a “seizure.” His abdominal pain started a few hours prior to presentation, was sharp in nature, and radiated to his back and umbilicus. The pain waxed and waned, worsened when he walked or sat up, and at its worst was a 10/10. He took a laxative and two antacids, but received no relief.Each “seizure” episode lasted about 30 seconds and occurred every five minutes. He said he felt drained after each event but ...

ConclusionThe 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.ResumoIntroduçãoA colonoscopia mostra-se útil no diagnóstico de diversas patologias. Ao permitir a visualização direta da mucosa, possibilita a tomada de medidas terapêuticas, como a remoção de pólipos, dilatação de estenoses e realização de biopsias. Tal método pode ser empregado também no rastreio do c&aci...

Authors: Kameda C, Miwa H, Kawabata R, Marukawa D, Murakami M, Noura S, Shimizu J, Hasegawa J Abstract An inflammatory fibroid polyp (IFP) is a mesenchymal tumor of the gastrointestinal tract. IFPs in the small intestine are the most frequently detected with symptoms, such as abdominal pain and tarry stool due to intussusception. Accordingly, few studies have reported jejunal IFP as a cause of occult gastrointestinal bleeding (OGIB) diagnosed via both of capsule endoscopy (CE) and double-balloon enteroscopy (DBE). A 68-year-old woman presented with a progression of anemia and a positive fecal occult blood test resu...

Authors: Zhang L, Shen J, Guo L, Cheng F, Fan Q, Ni K, Xia S, Zhou D Abstract The present study aimed to determine the diagnostic yield of OMOM capsule endoscopy for small bowel diseases in adults. A total of 89 patients, including 45 cases of obscure abdominal pain, 22 of chronic diarrhea, 18 of obscure gastrointestinal bleeding and 4 of obscure anemia were enrolled in the present study. The transit time of the endoscopy capsule in the digestive tract was recorded and the testing results were analyzed. All detections were completed except for four capsule retentions and the completion rate was 95.51%. The average ...
