  • A 68-year-old Caucasian man with hepatitis C virus-related cirrhosis was admitted to our Unit in February 2010 for a diagnostic evaluation of three centimetric hypoechoic focal liver lesions detected by regular surveillance ultrasound. (wjgnet.com)
  • As KevinMD suggests, this could instigate a turf war between radiologists and gastroenterologists as both specialties fight to tout their procedure as the surveillance technique of choice of colorectal cancer. (buckeyesurgeon.com)
  • The perforation rate was 2.5% for all 238 lesions removed by ER and 6.3% for the 96 lesions removed by ESD. (bvsalud.org)
  • Conclusions Colorectal ESD using PCM-CT is a simple and promising method. (thieme-connect.com)

  • Preliminary study results demonstrated parenchyma-sparing surgery (PSS) as an effective approach which allowed to remove colorectal cancer (CRC) metastatic lesions within the central liver cites and increased the probability of the liver re-resections. (biomedcentral.com)
  • 8.3 Model-based evaluation of liver focal lesion data. (who.int)
  • Lesions were of Paris type 0-Is with pit pattern type V (n = 8), 0-IIa (n = 33), 0-IIa + Is (n = 36), and 0-IIa + IIc (n = 5). (nih.gov)
  • A total of 1774 of 3454 (51%) mucosal lesions were located in the right colon, 1212 (35%) in the left colon, and 468 (14%) in the rectum. (bmj.com)
  • Protruded sessile lesion (T0 Is) with 16 mm, in the distal rectum. (spg.pt)
  • 8 Primary colorectal lymphomas are less frequent, accounting for only 0.2% of all colonic neoplasms. (consultant360.com)
  • however, CT scan and mammography were unable to identify the site of the primary lesion. (biomedcentral.com)
  • Immunohistochemical reevaluation showed the cervical lymph node biopsy specimen to be positive for CDX2 and CK20 and negative for CK7 expression, leading us to suspect the presence of a primary colorectal cancer. (biomedcentral.com)
  • The lesion was found to have an intramucosal cancer component, demonstrating that this lesion represented primary colon cancer. (biomedcentral.com)
  • Whole-body computed tomography (CT) showed systemic lymph node swellings (left supraclavicular and multiple para-aortic lymph nodes) but no primary lesion (Figure 1 ). (biomedcentral.com)
  • An alternative strategy for bilobar CRC involves parenchyma-sparing surgery (PSS) of all bilobar metastatic lesions within one surgical procedure. (biomedcentral.com)

  • Pulmonary carcinoids are well differentiated low to intermediate grade lung neuroendocrine tumours (LNETs), that belong to the group of lung neuroendocrine neoplasms which also include highly aggressive lung neuroendocrine carcinomas (LNECs). (who.int)
