Abstract Background and study aims The optimal approach to small subepithelial tumors (SETs) of the upper gastrointestinal tract remains inconclusive. The aim of this study was to evaluate endoscopic ultrasound-guided fine needle biopsy (EUS-FNB) for less invasive tissue sampling of small SETs of the upper gastrointestinal tract. Patients and methods In this prospective observational study patients with small ( ≤ 3 cm) SETs of the upper gastrointestinal tract were eligible and underwent EUS-FNB with a 22-gauge core biopsy needle. The main outcome measure was the diagnostic yield. The number of obtained core biopsies was also assessed. Results Twenty patients were included. The mean SET size was 16 mm (range 10 – 27 mm). EUS-FNB was technically feasible in all cases and no complications were observed. The diagnostic yield was 75 %. Core biopsy specimens were obtained in only 25 % of cases. Conclusion EUS-FNB with a 22-gauge core biopsy needle of small SETs can achieve a definite diagnosis in the majority of cases. However, because core samples cannot regularly be obtained, EUS-FNB seems not to be convincingly superior to standard EUS-FNA in this setting

Abstract Background and study aims Endoscopic ultrasound (EUS)-guided tissue acquisition is sometimes required to diagnose small solid pancreatic lesions. The aim of this study was to evaluate the diagnostic yield of EUS-guided tissue acquisition for small solid pancreatic lesions and the differences in diagnostic yield among different needles. Patients and method We retrospectively analyzed consecutive patients who had undergone EUS-guided tissue acquisition for solid pancreatic lesions less than 2 cm between November 2012 and June 2019. Three types of needles were evaluated in this study: a 22-gauge fine-needle aspiration (FNA) Lancet needle, a 20-gauge fine-needle biopsy (FNB) Menghini needle with a lateral forward bevel, and a 22-gauge FNB Franseen needle. We evaluated the diagnostic yield and safety of the procedure using these needles. Results We analyzed 160 patients with 163 lesions. The overall sensitivity, specificity, and accuracy were 92.0 %, 100 %, and 92.6 %, respectively. In the histological plus cytological diagnosis, accuracies of the Lancet, Menghini, and Franseen needles were 92.7 %, 97.0 %, and 85.7 %, respectively (P = 0.10). In the histological diagnosis alone, the negative predictive values (NPVs) of the Lancet, Menghini, and Franseen needles were 13.3 %, 53.3 %, and 27.3 %, respectively (P = 0.08). Adverse events occurred in four cases (2.5 %): one postprocedural bleeding, two cases of pancreatitis, and one pancreatic abscess. Conclusions EUS-guided tissue acquisition for small solid pancreatic lesions has a high diagnostic yield and safety. This study suggested a difference in the diagnostic yield of each needle for small solid pancreatic lesions.

Abstract Background: Endoscopic ultrasound-guided tissue acquisition (EUS-TA) is an established diagnostic procedure for solid pancreatic mass. However, the diagnostic yield between fineneedle aspiration (FNA) and fine-needle biopsy (FNB) remains unclear. Thus, we aimed to evaluate and compare the diagnostic yields between FNA and FNB using conventional FNA and Franseen needles of the same size (22 gauge), respectively, in patients with solid pancreatic mass who underwent EUS-TA without rapid onsite cytopathology evaluation (ROSE). Methods: All cases of EUS-TA by FNA or FNB for solid pancreatic mass between January 2017 and October 2020 in a single center university hospital were retrospectively reviewed. The procedure was performed without an onsite cytologist. After macroscopic onsite evaluation (MOSE), the endoscopist finished the procedure. The diagnostic yield and the average number of needle passes between FNB and FNA were then compared. Results: A total of 151 patients (FNA, n = 77; FNB, n = 74) with solid pancreatic mass detected by cross-sectional imaging underwent EUS-TA. The mean age was 62.3 ± 12.8 years, with 88 (58.3%) males. Age, gender, mass location, tumour size and disease stage from imaging were not significantly different. The diagnostic performance was dramatically higher in EUS-FNB (100%) than in EUS-FNA (89.6%). The mean number of needle passes was clearly fewer in FNB than FNA (2.8 vs. 3.8, p < 0.001). The total procedure time was less in FNB (34.7 minutes) than in FNA (41 minutes). The adverse event rate between FNB and FNA was not significantly different. Conclusions: The diagnostic performance for solid pancreatic mass without ROSE was significantly higher in FNB than in FNA. The number of needle passes and the total procedure time was also lesser in FNB.
