Congenital anomalies such as positional anomalies of the right half of the colon are more common when compared to its left half. We report a rare case of congenital anomaly where the transverse colon was totally absent. Ascending colon continued as descending colon at the right colic flexure. Ascending and descending colons formed an inverted U shaped loop which was situated in the right half o...

Deep learning has shown excellent performance in analysing medical images. However, datasets are difficult to obtain due privacy issues, standardization problems, and lack of annotations. We address these problems by producing realistic synthetic images using a combination 3D technologies generative adversarial networks. propose CUT-seg, joint training where segmentation model jointly trained p...

Growth hormone (GH) excess in acromegaly is associated with increased precancerous colon polyps and soft tissue adenomas, whereas short-stature humans harboring an inactivating GH receptor mutation do not develop cancer. We show that locally expressed colon GH is abundant in conditions predisposing to colon cancer and in colon adenocarcinoma-associated stromal fibroblasts. Administration of a G...

Purpose . To assess the effectiveness of standard and modified settings fujinon intelligent color enhancement (FICE) technology in differential diagnostics colon epithelial formations including their morphological type. Description clinical cases The presented demonstrate FICE mode endoscopic superficial neoplasms colon. proposed technique simplifies routine examination allows to determine a ma...

Ischemic colitis is thought to be an injury the colon as a result of reduced blood flow. Certain infectious diseases such Epstein-Barr virus can aid in reduction The insult range from inflammation and superficial full-thickness necrosis. typical regions affected are “watershed” areas colon: splenic flexure, rectosigmoid junction, right colon. Because patients present with wide spectrum symptoms...

Previous studies report controversial role of Hedgehog (HH) signaling in the progression of colon cancer. This study aimed to investigate the expressions of smoothened (SMO) and downstream glioma-associated oncogene homology-1 (GLI1) in colon cancer, colonic adenoma and normal tissues. Colon cancer and normal tissue samples were collected from 49 patients with colon cancer while colonic adenoma...

1, 2-Dimethylhydrazine (DMH) was administered to a total of 131 Wister Furth substrain (WF /0) rats 20 times weekly at a dose of 20 mg/kg body weight. The tumors were more predominant in the ascending colon (.64/148) than in the descending colon (13/148). Examination of the apparently normal colon after the 20th injection of DMH revealed that both the ascending (P<O. 01) and descending colon ep...

microRNA (miRNA) dysregulation is frequently observed in colon cancer. Previous studies found that miR-223 is upregulated in colon cancer and functions as an oncogene. Conversely, p120 is often downregulated or even absent in colon cancer, and is a likely tumor suppressor. The present study showed that increased miR-223 and decreased p120 levels are associated with colon cancer malignancy, and ...

When performing endoluminal surgery inside the colon using a flexible endoscopic robot, there is problem of losing visualization and task space due to collapsing surrounding wall. This happens mainly because intra-abdominal pressure peristalsis colon. Although insufflation commonly used for expanding colon, it does not function when full-thickness incision created on To support ensure sufficien...
