PURPOSE In surgery for rectal cancer, it is unclear whether the inferior mesenteric artery should be ligated at a high or low position. The study contained herein was undertaken to clarify the indications for high ligation of the inferior mesenteric artery. METHODS Subjects included 198 patients with rectal cancer who underwent resection with high(More)
PURPOSE Few reports on the long-term functional outcome of colonic J-pouch reconstruction have been published, and data comparing J-pouch and straight reconstruction are contradictory. This prospective study compares the functional outcome of colonic J-pouch and straight anastomosis five years after low anterior resection for rectal cancer. METHODS(More)
BACKGROUND Metastasis to regional lymph nodes from colon cancer is an important prognostic factor. In the TNM classification, node metastases are classified into three grades based on the number of metastatic nodes. In the Japanese General Rules for Clinical and Pathologic Studies on Cancer of the Colon, Rectum, and Anus (JGR), node metastases are(More)
PURPOSE Functional outcome after anterior resection for rectal cancer is improved by colonic J-pouch reconstruction compared with straight anastomosis. The indications for colonic J-pouch reconstruction have yet to be determined. Therefore, we attempted to determine the level at which J-pouch reconstruction provides an advantage over straight anastomosis.(More)
PURPOSE In colon cancer surgery, it is recommended that en bloc resection involving extended lymphadenectomy, characterized as a hemicolectomy, be performed by ligating the primary feeding artery at a high position and resecting proximal and distal with 5-cm to 10-cm bowel margins. However, there is little evidence to unequivocally support such extensive(More)
To evaluate the long-term functional outcome of colonic J-pouch reconstruction after low anterior resection (LAR) for rectal cancer in a prospective study. We compared the functional outcome of 46 patients who underwent J-pouch reconstruction (J-group) and 49 patients who underwent straight anastomosis (S-group) after LAR for rectal cancer. We evaluated(More)
The local recurrence rate after total mesorectal excision (TME) appears to be markedly lower than that after conventional operations. We reviewed all relevant articles identified from the MEDLINE databases and clarified the rationale for TME. It is clear that distal intramural spread is rare. Even when present, such spread is not likely to extend beyond 2(More)
PURPOSE We examined the survival benefit of pelvic exenteration for locally advanced colorectal cancer with lymph node metastases, because this issue remains controversial. METHODS Medical records of 50 patients who underwent curative pelvic exenteration for colorectal cancer were reviewed retrospectively. Nodal metastases were examined by the clearing(More)
PURPOSE Bowel function after low anterior resection for rectal cancer with colonic J-pouch reconstruction is more normal than after conventional straight anastomosis. However, few reports have examined the function of colonic J-pouch reconstruction in the elderly. Good function would obviate the need for colostomy, which is sometimes performed because of(More)
PURPOSE Although the functional outcome after low anterior resection for rectal cancer using colonic J-pouch reconstruction is superior to that using conventional straight reconstruction, the one drawback of colonic J-pouch reconstruction is difficulty with evacuation. Recently it has been suggested that construction of a larger colonic J-pouch causes the(More)
