“…This method is based on the notion that a large amount of cored, good-quality tissue with little contamination may be able to be acquired by reducing the number of strokes as much as possible. In addition, even the transduodenal approach resulted in sufficient tissue collection in all 16 patients [23] as well as in 1 patient included in our study (100%), despite some rigidity. Taken together, these results strongly support the notion that this 21-gauge Menghini-type biopsy needle with the rolling method can be a reliable way of obtaining abundant tissue with preserved architecture for a histological evaluation in order to make a diagnosis of AIP.…”

“…Keeping the inner needle inside the outer needle during suction improves the ability to obtain adequate core tissue with preservation of a non-crushed tissue architecture. Indeed, this report revealed that the use of this needle was strongly associated with high cellularity (OR = 2.99, 95% CI 0.96-9.74, P = 0.062) and low blood contamination (OR = 28.63, 95% CI 6.67-162.44, P < 0.001) in a histological evaluation [23]. Remarkably, those good-quality tissue with less blood contamination was also achieved in our cases, as shown in Fig.…”

“…Recently, this 21-gauge Menghini-type biopsy needle was reported to be more useful for achieving the histopathological diagnosis of solid pancreatic masses than a standard 22-gauge needle [23,24]. The most important feature of this needle is the equipment of an inner needle with plunger.…”

“…For patients with segmental or focal pancreatic enlargement, puncture was performed via the transgastric or transduodenal route, depending on the location. Figure 1 shows the 21-gauge Menghini-type needle (EUS Sonopsy CY), which was originally made for performing liver biopsies (Sonopsy C1; HAKKO Medical) [23,24,28]. This needle has two features of note.…”

“…The 21-gauge Menghini-type biopsy needle is a newly developed needle for EUS-FNB that was recently reported to provide high-quality specimens for histological evaluations for the diagnosis of solid pancreatic masses, especially in terms of both sample cellularity and blood contamination, compared with a 22-gauge conventional needle [23,24]. The two special features of this needle, namely the tapered beveled-edge of the outer needle and the inner needle connected to a barrel equipped with an aspiration piston, can substantially improve the acquisition of ample tissue with little blood contamination.…”

Background The histological diagnosis of autoimmune pancreatitis (AIP) by an endoscopic ultrasound (EUS)-guided approach is still challenging. Methods We investigated the utility of the 21-gauge Menghini-type biopsy needle with the rolling method for the histological diagnosis of AIP, in comparison with conventional 22-gauge needles. Among total 28 patients, rate of definitive histological diagnosis, acquired sample area of tissue, rate of histopathological diagnosis of AIP, and adverse events were retrospectively analyzed. Results Definitive histological diagnoses were successfully accomplished in all 14 patients (100%) treated with a Menghini-type needle, and in 57% of cases (8/14) treated with conventional 22-gauge needles (P < 0.001). The median sample area of the tissue, except for blood contamination, was remarkably larger by the Menghini-type needle than by conventional-type needles (6.2 [IQR, 4.5–8.8] versus 0.7 [IQR, 0.2–2.0] mm2, P < 0.001), and the area per punctures was approximately 4 times larger (1.4 [IQR: 0.9–2.9] versus 0.3 [IQR: 0.1–0.6] mm2/puncture, P < 0.001). Based on the International Consensus Diagnostic Criteria, lymphoplasmacytic infiltration, abundant IgG4-postive cells, storiform fibrosis, and obliterative phlebitis were found in 86%/29%, 64%/0%, 36%/0%, and 7%/0% patients who were treated with the Menghini-type needle and conventional-type needles, respectively. Consequently, histopathological diagnosis with type 1 AIP (lever 1 or 2) was achieved in 9 patients (64%) treated with the Menghini-type needle and in no patient treated with conventional-type needles (P < 0.001). Two patients who had mild post-procedural pancreatitis improved with conservative treatment, and no bleeding occurred in patients treated with the Menghini-type needle. Conclusion EUS-guided rolling method with the 21-gauge Menghini-type biopsy needle is useful for the histopathological diagnosis of AIP, due to its abundant acquisition of good-quality tissue from the pancreas.

Pancreatic carcinoma is an aggressive tumour with increasing incidence in both sexes worldwide. Early detection is, therefore, essential for patient management. A recent advancement involves the utilization of larger, thicker gauge needles, which enable the collection of core‐type biopsies (FNB). Here, we investigated the role of fine needle aspiration and cytopathology in the diagnostic workflow of pancreatic lesions. A search query was designed to search for articles in the PubMed database comparing FNA and FNB for biopsy of pancreatic lesions, and detailed data were extracted from selected studies. Statistical analyses were performed using the R package meta version 6.2. Twenty‐one studies made the final cut for data extraction. Overall, median age was 64.3 years (±6.1; 47.6–71.5), male: female proportion 53.9 (±11.3; 27.6–67.4), lesion size 3.1 cm (±0.5; 1.9–4.2 cm) and percentage of malignant cases 78.3% (±26.8; 2.1–100). FNA and FNB diagnostic yield was 85.8% (±10.3; 70.0–100.0) and 89.2% (±7.7; 70.0–98.6), respectively. Average accuracy was 89.5% (±11.7; 63.0–100.0) for FNA and 90.8% (±7.1; 77.0–100.0) for FNB. Adverse effects rate was 1.0% (±1.3; 0–4.3) for FNA and 2.2% (±4.4; 0–16.1) for FNB. None of the selected variables had a significant statistical difference between both methods. FNA and FNB perform similarly for diagnostic material acquisition in pancreatic lesions. The best outcome comes from the association of both techniques, emphasizing the value of combining cytological and histological morphology for the most accurate analysis.
