V delta 1 bearing T cells comprise the major population of gamma/delta T cells in the human intestinal tract. To gain insight into mechanisms involved in the generation of these cells and the diversity of their repertoire, we have characterized the junctional sequences of V delta 1 T cell receptor transcripts in the human small intestine and colon. Mucosal biopsies obtained from defined regions...

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...

Primary mesenchymal tumors of the colon are extremely rare tumors among soft tissue sarcomas. These tumors are more aggressive and have poorer prognosis than adenocarcinoma of the colon. Here, we presented 3 cases of primary mesenchymal tumors of the colon. Their histopathological diagnoses are leiomyosarcoma, pleomorphic liposarcoma, and desmoplastic small round cell tumor, respectively. The r...
