conclusions rtesd in the prone position is safe and presents a feasible alternative for management of large rectal tumors. we also anticipate the technique to further improve with the advancement of robotic technology. introduction endoscopic submucosal dissection (esd) of large tumors of the rectum is particularly challenging using colonoscopy or with laparoscopic instruments. more recently ro...

background: in recent years, neoadjuvant chemoradiation and subsequent surgical resection with total mesorectal excision has been shown to increase local control with decreased toxicity. neoadjuvant chemoradiotherapy is the standard treatment for locally advanced rectal cancer. in this study we evaluated the efficacy a cox-2 inhibitor on pathologic response, sphincter preservation and acute tox...

  Rectal cancer is the second most common cancer in large intestine. The prevalence and the number of young patients diagnosed with rectal cancer have made it as one of the major health problems in the world. With regard to the improved access to and use of modern screening tools, a number of new cases are diagnosed each year. Considering the location of the rectum and its adjacent organs, ma...

BACKGROUND Rectal cancer patients that show a pathological complete response (pCR) after neo-adjuvant chemo-radiotherapy, have better prognosis. To increase pCR rates several studies escalate the tumor irradiation dose. However, due to lacking tumor contrast on online imaging techniques, no direct tumor setup can be performed and large boost margins are needed to ensure tumor coverage. The purp...

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...

BACKGROUND Rectal cancer with rectal prolapse is rare, described by only a few case reports. Recently, laparoscopic surgery has become standard procedure for either rectal cancer or rectal prolapse. However, the use of laparoscopic low anterior resection for rectal cancer with rectal prolapse has not been reported. CASE PRESENTATION A 63-year-old Japanese woman suffered from rectal prolapse, ...

  Lipomas of the gasterointestinal Tract are relatively uncommon in clinical practice. Most cases are asymptomatic with small tumor size and do not need any special treatment but the large ones are known to cause symptoms such as abdominal pain, obstruction, intussusceptions, and bleeding. The majority (90%) of these lesions are submucosal with predominantly right sided with a slight preponder...

A case is presented of rectal carcinoma in which during staging by endoscopic ultrasound (EUS) a second large extrarectal mass was seen not otherwise visualized on computer tomography (CT) that was a solitary ovarian metastasis. The surgeon was alerted to the EUS finding prior to the planned laparoscopic colectomy. On retrospective review of the CT pelvis after surgery, the radiologist could st...

PURPOSE To determine whether large rectal volume on planning computed tomography (CT) results in lower tumor regression grade (TRG) after neoadjuvant concurrent chemoradiotherapy (CCRT) in rectal cancer patients. MATERIALS AND METHODS We reviewed medical records of 113 patients treated with surgery following neoadjuvant CCRT for rectal cancer between January and December 2012. Rectal volume w...
