A better diagnostic rate of 81.5% of EUS-FNA using a forward-viewing echoendoscope
and 19 G needle for SELs <2 cm in size was reported in 27 patients (26).
Endoscopic procedures were performed with the use of duodenoscope Pentax ED3490TK and echoendoscope
EUS examination was done in all patients with a Pentax linear Echoendoscope
EG3870UTK (PENTAX medical, Tokyo, Japan) attached to a Hitachi Avius ultrasound system (Hitachi Medical Systems, Tokyo, Japan).
With patients under conscious sedation, the lineer EG-3870 UTK echoendoscope
(Pentax) was used to scan the pancreatic head, body, and tail at 7.5 MHz.
EUS using a linear-array echoendoscope
(PENTAX EG-3870UTK) revealed two well-defined hypoechoic lesions with similar echotexture firstly in the mediastinum posterior to the left main stem bronchus and secondly in the pancreatic body.
In some cases, echoendoscope
can be used but it is unlikely to perform this exam in all patients with endometriosis unless a MR or CT imaging suggests proximal bowel endometriosis.
The extrahepatic bile duct was visualized from the duodenal bulb using a curved linear array echoendoscope
(GF-UCT260; Olympus Medical Systems Co., Tokyo, Japan) and then punctured using a 19-G fine-aspiration needle (Expect 19 G; Boston Scientific, Natick, Massachusetts, USA).
Following conscious sedation (with intravenous fentanyl and Diazemuls, Actavis, Pfizer, Canada), a curvilinear echoendoscope
(GFUC140P; Olympus, Toyko, Japan) was advanced into the upper gastrointestinal tract.
Endoscopic ultrasound-guided drainage of pancreatic pseudocysts using a large-channel echoendoscope
and a conventional polypectomy snare.
The electronic radial echoendoscope
was used to perform the EUS.
The procedure was performed with a linear echoendoscope
(GF-UCT 180; Hitachi Aloka Pro-Sound F75, Japan), from a bulbar position, upstream of the duodenal stenosis.
