چکیده
stromal tumor that develops from gastro-intestinal (GI) mesenchymal cells from the esophagus to the rectum. Before 1990, most investigators thought these mesencgymal cell tumor to be the neoplasm from smooth muscle of gastrointestinal tract, and considered that these tumors were one kind of leiomyoma, leomyosarcoma or leiomyoblastoma. With the advent of immuno-chemical staining and ultra-structural tissue examination, many physicians thought these tumors were another group of gastrointestinal mesenchymal tumors and it is different from the tumor from J Soc Colon Rectal Surgeon (Taiwan) December 2009

Transanal Minimally Invasive Surgery for Rectal Lesions
BACKGROUND AND OBJECTIVES Transanal minimally invasive surgery (TAMIS) has emerged as an alternative to transanal endoscopic microsurgery (TEM). The authors report their experience with TAMIS for the treatment of mid and high rectal tumors. METHODS From November 2011 through May 2016, 31 patients (21 females, 68%), with a median age of 65 years who underwent single-port TAMIS were prospective...
متن کاملNeoadjuvant imatinib treatment and laparoscopic anus-preserving surgery for a large gastrointestinal stromal tumor of the rectum
BACKGROUND Resection of a gastrointestinal stromal tumor (GIST) of the rectum can be difficult because of the particular location in the pelvis, and a large rectal GIST often requires abdominoperineal resection. Recent reports demonstrate that neoadjuvant imatinib treatment improves surgical outcomes in patients with a rectal GIST, and there are only a few reports of the effectiveness of laparo...
متن کاملSurgicel® (oxidized regenerated cellulose) granuloma mimicking local recurrent gastrointestinal stromal tumor: A case report
Unexpected clinical and/or imaging evidence of the recurrence of gastrointestinal stromal tumors soon after surgical resection may be complicated due to certain biological behavioral features of gastrointestinal stromal tumors. However, local hemostatic materials routinely used in abdominal surgery to achieve hemostasis intraoperatively may cause a foreign-body reaction, which appears to be ind...
متن کاملMalignant gastrointestinal stromal tumor of the rectum with prolapse.
G stromal tumors are rare tumors of the gastrointestinal tract, and they account for less than 1% of gastrointestinal neoplasms. Most of these tumors may not originate from smooth muscles. With the advent of electron microscopy, interstitial cells of Cajal, a pleuropotential intestinal pacemaker cell, was found as the originator of gastrointestinal stromal tumors.1 The stomach is a common site ...
متن کاملGastric Calcifying Fibrous Tumor Resembling Gastrointestinal Stromal Tumor: A Case Report
Calcifying fibrous tumor (CFT) is a rare mesenchymal tumor, affecting children and young adults with a predilection for the soft tissue and the abdominal cavity. CFT of the tubular gastrointestinal tract is very rare with less than 20 cases of gastric CFTs reported in English literature. This benign hypocellular fibrosclerotic calcifying lesion can resemble other spindle cell tumors particularl...
