PURPOSE Whether preoperative chemoradiotherapy (CRT) is better than postoperative CRT in oncologic outcome and toxicity is contentious in prospective randomized clinical trials. We systematically analyze and compare the treatment result, toxicity, and sphincter preservation rate between preoperative CRT and postoperative CRT in stage II-III rectal cancer. MATERIALS AND METHODS We searched Med...
AIM OF THE STUDY In patients from the Dutch TME trial patterns of local recurrence (LR) in rectal cancer were studied. The purpose was to reconstruct the most likely mechanisms of LR and the effect of preoperative radiotherapy. METHODS 1417 patients were analyzed; 713 were randomized into preoperative radiotherapy and total mesorectal excision (RT + TME), 704 into TME alone. Of the 114 patien...
Calcifying fibrous pseudotumors are rare soft-tissue lesions pathologically characterized by hyalinized collagen, psammomatous or dystrophic calcification, and lympho-plasmacyte infiltration. They are clinically benign with an extremely low rate of recurrence and complete surgical resection is known to be the treatment of choice. We performed the resection of a calcifying fibrous pseudotumors i...
In 2012, rectal cancer affected 40,290 Americans. Colon and rectal cancer resulted in a mortality of 51,690 individuals during the same year [1]. Patients affected with rectal cancer who have a clinical stage II (T3-T4, NO, MO) or III (Any T, N1-N3, M0) tumor are treated with preoperative chemoradiation (CRT) followed by surgical intervention 5-10 weeks after the last CRT treatment. An adequate...
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...
Abstract Background: Correction of severe kyphosis is a challenging operation in spinal surgery. A two stage operation has been commonly used: anterior release and decompression followed by posterior correction and fusion. We describe the posterior vertebral osteotomy technique for correction of severe and rigid kyphosis through posterior-only approach. Methods: Twelve patients (six male and s...
BACKGROUND The position of arterial ligation during laparoscopic anterior rectal resection with total mesorectal excision can affect genito-urinary function, bowel function, oncological outcomes, and the incidence of anastomotic leakage. Ligation to the inferior mesenteric artery at the origin or preservation of the left colic artery are both widely performed in rectal surgery. The aim of this ...
