Background:
No studies have compared balloon-assisted endoscope-guided endoscopic retrograde cholangiopancreatography (BAE-ERCP) and endoscopic ultrasonography-guided biliary drainage (EUS-BD) for emergent treatment of acute cholangitis (AC) in patients with upper gastrointestinal surgically altered anatomy (SAA).
Methods:
This study retrospectively evaluated consecutive patients who underwent emergent BAE-ERCP or EUS-BD for AC with SAA between January 2020 and March 2024. Technical success, clinical success, procedure time, and adverse events (AEs) were compared between the two groups.
Results:
This study included 23 patients in the BAE-ERCP group and 14 patients in the EUS-BD group. Technical success and clinical success rates did not significantly differ between the two groups (88% vs. 100%, P = 0.51 and 95% vs. 93%, P = 0.66). Similarly, the rate of AEs was comparable between the two groups (4% vs. 14%, P = 0.54). The median procedure time was significantly shorter in the EUS-BD group than in the BAE-ERCP group (32.5 [interquartile range; IQR, 28.8–52.5] minutes vs. 70.0 [IQR, 60.0–90.0] minutes, P < 0.01). In cases with grade 2 or 3 cholangitis, the rates of technical success, clinical success, and AEs did not significantly differ between the two groups. However, the median procedure time was significantly shorter in the EUS-BD group than in the BAE-ERCP group (32.5 [IQR, 28.8–52.5] minutes vs. 70 [IQR, 56.3–90.0] minutes, P < 0.01).
Conclusion
While both BAE-ERCP and EUS-BD can be performed safely and effectively in patients with AC and SAA, the procedure time is significantly shorter with EUS-BD than with BAE-ERCP.

Background:
Endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) has been recognized as an effective treatment for patients at high risk for surgery. An antimigration metal stent with tapered thin delivery system has recently been developed. The aims of this study were to evaluate the feasibility, safety, and longterm outcomes of EUS-GBD using the new metal stent.
Methods:
Between April 2017 and March 2020, 21 patients with acute cholecystitis unsuitable for cholecystectomy underwent EUS-GBD using the metal stent. The stent was 6 mm in diameter and 6 cm in length, with a large flare at both ends for antimigration, and mounted in a 7.5 Fr delivery catheter, which requires no dilation devices. We retrospectively evaluated clinical and technical success, adverse events, and stent patency.
Results:
The technical and clinical success rates of EUS-GBD using the metal stent were 95.2% and 100%, respectively. For 75% of the patients, metal stents could be placed without dilatation of the needle tract. These patients had significantly shorter procedure time (23.6 ± 9.8 min) than patients requiring needle tract dilatation (38.4 ± 17.1 min; P = 0.036). The median follow-up periods were 336 days (interquartile range [IQR] 152–919 days) and 1,135 days (IQR 1,009–1,675 days) for all and alive patients, respectively. No adverse events or recurrence of cholecystitis due to stent occlusion that occurred in any patient at follow-up was observed.
Conclusion
In conclusion, EUS-GBD using the newly designed metal stent showed excellent safety and longterm outcomes, and may be suitable as an alternative treatment in patients who are unsuitable for cholecystectomy.

Background: Factors requiring midazolam in addition to systemic opioids to control dyspnea in cancer patients have yet to be evaluated. Methods: We retrospectively analyzed data for cancer patients who received systemic opioids to relieve dyspnea from April 2019 to July 2021 in Wakayama Medical University Hospital, Japan. Patients were divided into an opioid-alone group and an opioid plus midazolam group, according to the treatment of dyspnea. Results: The total of 107 patients included 85 patients (79.4%) in the opioid alone group and 22 patients (20.6%) in the opioid plus midazolam group. Age<60 years (p=0.004) and male sex (p=0.034) was significantly associated with the addition of midazolam. Multivariate analysis found age <60 years (OR=5.34, 95%CI: 1.66–17.21; p=0.005) was associated with the addition of midazolam. Conclusion: Age <60 years is factor requiring midazolam in addition to systemic opioids to control dyspnea in cancer patients.

Maxillofacial Plastic and Reconstructive Surgery 2022;44(1):6-
Background:
No studies have compared the outcomes of direct perineurial suture with vein graft cuff repair and indirect collagen allograft repair of the lingual nerve following an injury. Therefore, we evaluated and compared the outcomes of each over a 1-year observation period. We retrospectively assessed 20 patients who had undergone microneurosurgical repair of unilateral lingual nerve injuries at the Wakayama Medical University Hospital between May 2015 and March 2019. We utilized two different methods for lingual nerve repair, i.e., direct perineurial repair with a vein graft cuff and interpositional collagen allograft repair. Sensory and taste function in the lingual nerve were preoperatively evaluated using a static two-point discrimination test, superficial pain/tactile sensation test, tests for the pressure pain threshold (Semmens-Weinstein monofilament), test for thermal discrimination hot and cold sensation, and a taste discrimination test. These tests were performed again at 6 and 12 months postoperatively.
Results:
Compared to the preoperative conditions, all patients showed improved sensory reactions. Functional sensory recovery outcomes were defined by Pogrel’s criteria, Medical Research Council Scale grades, and functional sensory recovery. In each group, all patients improved after the operation. However, the operation time was significantly shorter for an interpositional collagen allograft repair as compared to that for a direct perineurial repair with a vein graft cuff.
Conclusions
There were no statistically significant differences between the two repair Methods, except for the operation time. Both methods led to satisfactory results for all criteria. From an economic point of view, direct perineurial repair with a vein graft cuff is meaningful; however, the esthetic effect on the donor site should be considered. Conversely, interpositional collagen allograft repair has the advantage of a greatly shortened operation time.

Although it is not yet common, certified Kampo (traditional Japanese medicine) doctors and acupuncturists are cooperating with each other to provide traditional medical treatment for patients in some general hospitals in Japan. In other hospitals, however, Kampo and acupuncture-moxibustion have not been introduced, and doctors only treat patients using modern Western medicine. Many doctors must already be aware that modern Western medicine is not the only approach for the treatment of patients, but they do not make any efforts to improve the situation by adopting traditional medicine. Here, we give some examples of hospitals in which acupuncture treatments are routinely provided, having a favorable effect on both patients as well as the hospitals themselves. We believe that these examples give us a good opportunity to consider the future of an ideal medical system in which modern Western medicine and traditional Japanese medicine are successfully integrated.

A commemorative lecture meeting on the inclusion of a new chapter of traditional medicine in ICD-11 was held in Tokyo in February 2020. The head of the Collaborating Centre for WHO-FIC in Japan explained the process of the project, which started in 2006 to increase WHO's data collection from developing countries and expressed gratitude to the concerned persons who made efforts to obtain consensus with China and Korea. WHO promoted integrated coding between traditional medicine and Western medicine. In the field of acupuncture, meridian and collateral patterns proposed by Japan were adopted and research activities have begun. In the field of Kampo medicine, the prescription content is often used in a fixed form as a representative formula pattern in Japan, so clinically high-level research will be possible under this new classification. In the field of medical information, it has been pointed out that there are high hurdles for medical information managers to understand traditional medicine. It is expected that the progress of mutual understanding of both medicines. From now on, activities in research, translation, education and dissemination of this new classification should be promoted.
