Abstract
- Endoscopic ultrasound-guided fine-needle aspiration is used for the diagnosis and evaluation of rectal and pelvic lesions in lower gastrointestinal tract disease. However, it is not used widely in proximal and transverse colon disease because of the limited visual field and technical problems related to an oblique-viewing echoendoscope. Here, we report a case of recurrent signet-ring-cell gastric adenocarcinoma involving the transverse colon not diagnosed by repeated colonoscopic biopsies that was eventually diagnosed using a forward-viewing echoendoscope with fine-needle aspiration biopsy.
