Proximal and distal clearance in centimetres for small bowel adenocarcinoma
Answers
Answer:
It has not spread into nearby tissue or lymph nodes (T1 or T2, N0, M0). Stage IIA: The cancer has spread through the wall of the small bowel, and it may have spread to nearby tissue. It has not spread to the nearby lymph nodes (T3, N0, M0).
Explanation:
The records of 79 patients with histology proven SBTs by surgery (43 patients) or double balloon enteroscopy (DBE, 65 patients) from March 2004 to December 2012 were retrospectively studied. Patients had been treated at 7 medical referral centers in Korea and had undergone surgery or DBE for SBT removal. We reviewed the clinical characteristics of SBTs; the diagnostic yields of SBFT, CT, and CE; and the characteristics of SBTs not detected by CE. Of these 79 patients, 39 (49.3%) underwent SBFT, 68 (86.1%) underwent CT, and 54 (68.3%) underwent CE before SBTs were confirmed. Findings of these diagnostic studies were interpreted by experienced endoscopists and radiologists, and the results were classified into three categories: definite, suspicious, or negative. When SBFT, CT, or CE revealed findings considered confirmatory of a diagnosis of SBT, the results were classified in the “definite SBT” category. When findings were suggestive but not confirmatory of SBT, the results were classified as “suspicious SBT.” When no evidence of neoplasia was found, the results were classified as “negative.” Locations of SBTs were classified as duodenum, jejunum (proximal, mid, or distal), and ileum (proximal, mid, or distal). In patients operated on, the locations of SBTs were classified according to operative findings. In patients nonoperated on, we approximately estimated the locations of SBTs with the depth of insertion of enteroscope, the size of small intestinal lumen, and the shape of villi and folds.
