Brief Summary:
The study is designed to evaluate the diagnostic accuracy of a new designed endoscopic ultrasonography (EUS) Core biopsy aspiration needle in comparison to a conventional EUS aspiration needle in GI-tumors.

Condition or disease Intervention/treatment Phase
Pancreatic Neoplasm Device: EUS guided FNA and fine needle punction Not Applicable

Detailed Description:

Endoscopic ultrasound is an established examination method for tumors of the gastrointestinal tract and the pancreas. Since imaging by itself is limited in differential diagnosis of tumors, EUS guided fine needle aspiration is seen as a valid complementary method. Since fine-needle aspiration (FNA) is mainly based on cytological diagnostics, this method is limited also because of lacking supplementary immune- histochemical diagnostics. Here, the obtainment of little histologically evaluable tissue samples (punched barrels) would be of benefit.

A new punch needle device called Pro-core needle (Cook)(22 / 19 gauges) offers the possibility of increasing numbers of valid extractions of histologically evaluable tissues due to a better targeted precision and maneuverability in comparison to other devices of that kind (tru-cut needles, e.g.). A little notch at the pinpoint allows the obtainment of little tissue samples, that will be kept within the device by aspiration.

This study compares the obtainment of tissue by Proc-core needle and conventional aspiration punction systems.

Arm Intervention/treatment
EUS guided FNA and fine needle punction
punction of endosonographically identified space-occupying process with aspirating fine needle and pro core fine needle in a randomized order
Device: EUS guided FNA and fine needle punction
punction of a suspect area by a EUS guided fine needle as well as pro core fine needle to evacuate histology and smear biologics

Primary Outcome Measures :
  1. Diagnostic Accuracy [ Time Frame: up to 1 year ]

    Diagnostic accuracy of Pro-core needle (22 G) will be compared to conventional fine needle aspiration (22 G). Therefore EUS-FNA with both needles is undertaken in a random order in each lesion. For Pro-core needle, a histological / cytological diagnosis and quality assessment will be made by pathologists.For Echotip aspiration needle, reference cytology evaluation is done by cytology experts.

    The histopathological diagnosis after surgery or the clinical follow up of at least one year after EUS FNA is current standard.

Secondary Outcome Measures :
  1. EUS Pro Core FNA: Histology Samples [ Time Frame: day 0 and day 14 ]
    Histology (not cytology) samples for Pro-core Needle: Number of adequately evaluable histology samples

  2. Complication Rates [ Time Frame: day 0 and day 14 ]
    Complication rates of EUS FNA
