Laparoscopic lateral pelvic lymph node dissection (LPLD) is a minimally invasive alternative to open surgical therapy for advanced low rectal cancer patients. This study assessed potential risk factors for lateral pelvic lymph node metastasis (LPLM) and evaluated the feasibility and oncological safety of laparoscopic LPLD compared with the conventional open(More)
We obtained diffusion-weighted echo planar images of the human cervical cord in vivo and correlated them with histopathologic findings. Images were obtained in 17 healthy volunteers using a 1.5 T clinical MR unit. When motion-probing gradients were added perpendicular to the long axis of the cord, the white matter was hyperintense because of anisotropic(More)
To delineate the white and gray matter of the normal human cervical spinal cord, diffusion-weighted echo planar imaging (DW-EPI) was performed in 11 healthy volunteers. Three axial (X-, Y- and Z-axis) anisotrophic diffusion-weighted images were obtained on a 1.5T superconducting clinical unit using a single-shot DW-EPI sequence. On X- and Y-axis DWIs the(More)
BACKGROUND Extranodal tumor deposits are involved in TNM classification. However, it is uncertain whether a tumor deposit is a regular lymph node metastasis, and its prognostic significance in patients with stage II or III colorectal cancer remains to be established. OBJECTIVE This study aimed to determine the prognostic significance of tumor deposits for(More)
BACKGROUND Early detection of colorectal cancer (CRC) is crucial to reducing tumor-related mortality. Evaluating aberrantly methylated DNA in stool is promising for CRC screening. However, DNA methylation in the colonic epithelium of background mucosa may compromise stool DNA (sDNA) test results. Thus, we compared aberrant methylation of cancer-related(More)
Reliable predictors of tumor recurrence for patients with stage II colorectal cancer (CRC) are needed to select patients who should receive adjuvant chemotherapy. Although galanin (GAL) is expressed in several malignant tumors and is associated with cell proliferation and tumor growth, the prognostic value of GAL expression in CRC is poorly understood. We(More)
We herein present a novel technique for laparoscopic en bloc excision involving anteriorly extended intersphincteric resection with partial resection of the posterior lobe of the prostate for large rectal gastrointestinal stromal tumors (GISTs). The sequence of neoadjuvant imatinib therapy and this less invasive surgery for marginally resectable rectal(More)
Sclerosing mesenteritis (SM) is a rare inflammatory and fibrosing disease primarily involving the small-bowel mesentery. Recently, SM was reported to be closely related to IgG4-related disease (IgG4-RD). This report describes a patient with SM associated with IgG4-RD. A 77-year-old woman with a history of surgery for ectopic pregnancy and wound dehiscence(More)
