56

Results

EUS-FNB with a 22-gauge Franseen needle demonstrated favorable detection rates which would be clinically beneficial for the histological diagnosis of autoimmune pancreatitis.

Baseline Characteristics

Forty-one of 56 patients were male, and the mean age was 66.7 years old. Fifty-five patients were clinically suspected to have type 1 AIP and only one patient was suspected to have type 2 AIP without histologic analysis.

Participant flow

Assessed for eligibility (Suspected AIP by imaging) (n=62)

Excluded
Not met the imaging criteria (n=3)
Diagnosed with pancreatic cancer by EUS-FNB (n=1)
Treated with steroid within 3 months before enrollment (n=1)
Tissue sample not sent to Nagoya University (n=1)

Enrolled for the study (n=56)

Adverse events

Two patients (4%) developed mild post-procedural abdominal pain immediately after the procedure, but they recovered within 24 hours without medication, and no patients required prolongation of admission due to adverse events. No other adverse events related to the EUS-FNB procedure were reported

Outcome measures

Lymphoplasmacytic infiltration, obliterative phlebitis, storiform fibrosis, and >10 IgG4-positive cells per high-power field were detected in 55 (100%), 24 (43.6%), 40 (72.7%), and 36 (65.4%) of 55 patients, respectively. The detection rates of level 1 and level 1 or 2 histology for AIP were 58.2% (95% confidence interval (CI) [44.1-71.3]) and 92.7% (95% CI [82.4-98]), respectively, which were apparently higher than our historical results (7.9%, 95% CI [1.7-21.4] and 62.2%, 95% CI [46.5-76.2]) using a conventional needle.
