Brief Summary

In the previous studies, EUS-guided fine needle aspiration (FNA) with fanning technique in solid pancreatic lesions (SPLs) with avascular areas had a negative impact on diagnostic accuracy of FNA. Because of the retrospective basis of previous studies, a prospective study is warranted to answer whether contrast-enhanced harmonic(CEH) EUS-guided FNA/B is superior to conventional EUS-guided FNA/B with fanning technique in SPLs. The main objective of this randomized trial therefore was to determine whether CEH-EUS-guided sampling to avoid non-enhanced areas within a mass lesion result in more rapid diagnosis requiring fewer FNB passes than the conventional EUS-guided FNB with fanning needle throughout the mass is targeted.

Outcome Measures

Primary Outcomes (1)

  • the median number of passes required to establish a diagnosis

    EUS-FNB is completed if the obtained macroscopic visible core (MVC) is longer than 4mm and deemed adequate by endoscopist

    1 day

Secondary Outcomes (2)

  • diagnostic accuracy rate

    3 months

  • overall complication rate

    3 months

Study Arms (2)

CEH-EUS-guided FNB group

EXPERIMENTAL

In CEH-EUS-guided FNB group, needle puncture directly to the enhancing area 15-20 times without passing to the non-enhancing area was performed. After each pass, the needle is removed and the stylet will be introduced into the needle to extrude any aspirated material on a glass slide for inspection of the presence of a macroscopic visible core (MVC). The total length of the MVC will be measured before placement into a formalin bottle. EUS-FNB is completed if the obtained MVC is longer than 4mm and deemed adequate by endoscopist. If the obtained MVC is \< 4mm, the procedure is repeated until a MVC of ≥ 4mm is obtained and deemed adequate by endoscopist. A maximum of 7 passes is allowed.

Diagnostic Test: Endoscopic ultrasound-guided fine needle biopsy

Conventional-EUS-guided FNB with fanning technique group

ACTIVE COMPARATOR

In conventional-EUS-guided FNB with fanning technique group, the needle was positioned at four different areas within the mass and then moved back and forth four times in each area to procure tissue (4 × 4). After each pass, the needle is removed and the stylet will be introduced into the needle to extrude any aspirated material on a glass slide for inspection of the presence of a macroscopic visible core (MVC). The total length of the MVC will be measured before placement into a formalin bottle. EUS-FNB is completed if the obtained MVC is longer than 4mm and deemed adequate by endoscopist. If the obtained MVC is \< 4mm, the procedure is repeated until a MVC of ≥ 4mm is obtained and deemed adequate by endoscopist. A maximum of 7 passes is allowed.

Diagnostic Test: Endoscopic ultrasound-guided fine needle biopsy

Interventions

Under endoscopic ultrasound guidance, fine-needle biopsy is used to collect biopsy samples from solid pancreatic lesions throughout the digestive tract and is useful in diagnosing solid pancreatic lesions.
