Endoscopic retrograde cholangiopancreatography (ERCP) in patients with surgically altered anatomy is technically challenging. For example, scope insertion, selective cannulation, and intended procedures, such as stone extraction or stent placement, can be difficult. Single-balloon enteroscopy (SBE)-assisted ERCP has been used to effectively and safely address these technical issues in clinical practice. However, the small working channel limits its therapeutic potential. To address this shortcoming, a short-type SBE (short SBE) with a working length of 152 cm and a channel of 3.2 mm diameter has recently been introduced. Short SBE facilitates the use of larger accessories to complete certain procedures, such as stone extraction or self-expandable metallic stent placement. Despite the development in the SBE endoscope, various steps have to be overcome to successfully perform such procedure. To improve success, the challenging factors of each procedure must be identified. At the same time, endoscopists need to be mindful of adverse events, such as perforation, which can arise due to adhesions specific to the surgically altered anatomy. This review discussed technical tips regarding SBE-assisted ERCP in patients with surgically altered anatomy to increase success and reduce the risk of adverse events associated with ERCP.

Background/Aims: Endoscopic ultrasound-guided tissue acquisition (EUS-TA) using Franseen needles is reportedly useful for its high diagnostic yield. This study compared the diagnostic yield and puncturing ability of EUS-TA using 22-gauge cobalt-chromium (CO-Cr) needles with those of stainless-steel Franseen needles in patients with solid pancreatic lesions. Methods: Outcomes were compared between the 22-gauge Co-Cr Franseen needle (December 2019 to November 2020; group C) and stainless-steel needle (November 2020 to May 2022; group S). Results: A total of 155 patients (group C, 75; group S, 80) were eligible. The diagnostic accuracy was 92.0% in group C and 96.3% in group S with no significant intergroup differences (p=0.32). The rate of change in the operator (from training fellows to experts) was 20.0% (15/75) in group C and 7.5% (6/80) in group S. Stainless-steel Franseen needles showed less inter-operator difference than Co-Cr needles (p=0.03). Conclusions Both Co-Cr and stainless-steel Franseen needles showed high diagnostic ability. Stainless-steel Franseen needles are soft and flexible; therefore, the range of puncture angles can be widely adjusted, making them suitable for training fellows to complete the procedure.

We conducted a fact­finding survey about the difficulties of handling the telephone consultations at a Kampo medicine outpatient clinic. We extracted the details of consultations that could not be handled by an outpatient nurse alone from the descriptive data of the telephone responses described by the nurses in the sur­vey. We, then, identified the factors that were involved in the difficulties encountered in these consultations, and countermeasures were established and implemented. One year later, we compared and examined the status of telephone consultations between before and after the fact-­finding survey. We classified the telephone con­sultations that were difficult for the outpatient nurses to handle alone into four categories : (1) consultation about a physical disorder, (2) questions about prescribed Kampo medicines, (3) reports and questions based on the patient's own judgment, and (4) questions about treatment and hospitalization. Some of the questions about Kampo medicines included the continued use of the medicine and drug interactions, and the main topics of the survey's nurse self-­judgment reports were dose reductions and changes in Kampo medicine regimens. As a re­sult of the introduction of guidelines prepared by the nurses together with physicians at the clinics, the outpa­tient nurses became able to handle telephone consultations about frequently asked questions (FAQs). At 1 year after the survey, the number of cases of difficulties in handling telephone consultations decreased to less than half the original value, and no telephone consultations were made within 1 week after the patients' first visits to the outpatient clinic.
