“…The most dangerous potential complication is the peritoneal dissemination of cancer cells along the needle track after EUS-FNAB, but only one such case has been reported to date. Hirooka et al 10 detected peritoneal dissemination after EUS-FNAB in a patient with an intraductal papillary mucinous tumor. On the other hand, Fornari et al 20 reported that peritoneal dissemination occurred in only 1 of 10 766 patients who underwent extracorporeal US-FNAB at 33 institutions.…”

“…[5][6][7][8] However, the use of EUS-FNAB for pancreatic lesions has received little attention and the procedure has only been performed at a limited number of Japanese institutions, due to insufficient availability of equipment and possible complications. 9,10 To clarify the clinical status of EUS-FNAB in Japan, we retrospectively analyzed the Background. Endoscopic ultrasonography-guided fineneedle aspiration biopsy (EUS-FNAB) has come into widespread use, mainly in Western countries, as an efficient and safe method for the cytologic or histologic diagnosis of pancreatic cancer.…”

“…With the advent of the curved‐linear array echoendoscope, fine‐needle aspiration has proven to be a safe and valuable method for obtaining aspiration specimens for diagnostic and staging purposes. In addition, the curved‐linear array‐type EUS has the function of CDFI and can reveal the hemodynamics of the lesion 5–8 . Many studies using EUS in the evaluation of upper gastrointestinal tract and adjacent structures have been reported, but there have been few studies of the large intestine.…”

The patient was a 58-year-old woman. Gallbladder stones and occult blood in feces were detected during a physical check-up, then the patient was referred to Nagoya University Hospital. In this case the fistula was difficult to diagnosed by ultrasound and endoscopic ultrasound (EUS) of the upper intestinal tract because the gallbladder was filled with stones. Barium enema and endoscopic retrograde cholangiopancreatography did not reveal fistula. Curved-linear array EUS of the colon showed fistula.

Endoscopic ultrasonography (EUS) has high spatial and contrast resolution, and is thought to be one of the most reliable and efficient diagnostic modalities for pancreatobiliary diseases. Recent progress in EUS, especially in the development of the electronic scanning method, has enabled the application of several utilities and software of a high-end transabdominal ultrasound apparatus as an image-enhanced EUS. Tissue harmonic imaging (THI) is a novel US acquisition method that provides better US images by using second harmonic signals. The potential advantages of THI are improved lateral resolution, reduced side lobe artifact and an increased signal-to-noise ratio.EUS-elastography is another novel technique that provides information about the distributed pattern of tissue hardness. Clinical benefits of EUS-elastography for the differential diagnosis of pancreatic tumors and the evaluation of pancreatic fibrosis have been reported. It is necessary to develop a unified and objective method of imaging and analysis to increase the use of EUSelastography in the future.
