Two hundred and seventeen patients with AIP (90 FAIP patients and 127 DAIP patients) and 197 patients with pancreatic head cancer, who consecutively underwent EUS before the initiation of steroid therapy at our center from January 2013 to December 2018, were retrospectively included in the present study. The diagnosis of AIP met the revised Mayo clinic criteria (revised HISORt criteria) including features of histology, imaging, serology, other organs involvement, and response to steroid therapy.[15 (link)] The diagnosis of pancreatic duct adenocarcinoma was confirmed by surgical pathology or by cytology/histology after EUS-guided fine-needle aspiration or biopsy. The EUS examination was performed by experienced endosonographers with a radial or linear echoendoscope (GF-UM2000, GF-UCT260 or GF-UE260, Olympus, Tokyo, Japan) and ultrasonic processing system (EU-M2000, EU-ME1 or EU-ME2, Olympus, Tokyo, Japan; or ProSound α5, Aloka, Tokyo, Japan). EUS characteristics of the patients with AIP were compared with those of the PC patients. The study protocol conforms to the ethical guidelines of the 1975 Declaration of Helsinki (6th revision, 2008) and was approved by the Ethics Committee of our institution.
Prosound α5
Manufactured by Aloka
Sourced in Japan
The ProSound α5 is a diagnostic ultrasound system designed for medical professionals. It features a high-resolution display and intuitive user interface. The core function of the ProSound α5 is to provide clear and detailed ultrasound imaging to support clinical decision-making.

We used echoendoscope (GF-UCT260, GF-UCT240, and GF-UE260; Olympus Medical System, Tokyo, Japan) and ultrasound processer (Aloka ProSound α5 and F75) under conscious sedation for all patients. Both trainees and experts performed EUS, because our hospital is a teaching hospital. Trainees were assisted by experts as needed to ensure procedural quality when performing EUS.

TSH, FT4 and FT3 and anti-thyroid peroxidase antibodies (TPOAb), anti-thyroglobulin antibodies (TGAb) anti-thyrotropin receptor antibodies (TRAb), were measured as previously reported (11 (link)).
Thyroid ultrasound studies were performed by the same operator (VC) with patients in a supine position with the neck hyperextended, by using an Aloka machine (Aloka Prosound α5, Aloka, Tokyo, Japan) with a 7–13 MHz linear transducer.

Following DynaCT completion and data acquisition and reconstruction, the iGuide mode (Syngo X-workplace with Syngo DynaCT; Siemens AG, Germany) was selected and the lesion was positioned in the axial, sagittal and coronal planes using a cross. DynaCT was used as the pre-designed procedure for lesion site puncture. After preparing the needle entry area in a sterile fashion, local anesthetic agent (lidocaine hydrochloride) was applied. Laparoscopic ultrasound (LUS; ALOKA ProSound α5, Aloka, Tokyo, Japan) was used during microwave ablation probe (ECO-100AI10, ECO Microwave System Co, Nanjing, China) insertion in order to avoid injury to the large vessels and the bile duct. When the optimal insertion angle and depth was achieved, the specific power and time settings were typically 5–10 min with a 65 watt (W) ablation [15 (link)]. The duration of ablation was directly related to the quality of the surrounding liver tissue, lesion depth and demarcation line length. Finally, the pre- and post-ablation CT scans were overlayed to validate the ablation zone.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
