We present the case of a 76-year-old man who underwent preoperative endoscopic ultrasound-guided hepaticogastrostomy (EUS-HGS) for obstructive jaundice caused by pancreatic head cancer. The patient had obstructive jaundice and cholangitis during neoadjuvant chemotherapy. Transpapillary biliary drainage using endoscopic retrograde cholangiopancreatography was attempted; however, it was unsuccessful because of duodenal tumor invasion. Therefore, EUS-HGS was performed. Jaundice and cholangitis improved promptly after EUS-HGS, and stent obstruction and migration were not observed before surgery. The stent was safely removed during surgery, and no postoperative complications occurred. Most studies of EUS-HGS for preoperative biliary drainage have been small and retrospective, and few have examined the safety of intraoperative stent removal. The fistula in our patient was promptly identified and the stent was safely removed despite the relatively limited field of view during robot-assisted laparoscopy.The promising findings of our case report can be used to inform EUS-based surgical strategies for biliary drainage with obstructive jaundice.

The role of academic journals evolves with the times. Academic publishing is diversifying, shifting from traditional paper-based formats to broader dissemination through open access. In response to these developments-and to contribute to ongoing progress in medical education-Medical Education (Japan) has undertaken a comprehensive revision of its submission guidelines. As of January 17, 2025, all submissions, peer reviews, and editorial processes are being conducted in accordance with the updated guidelines. The Editorial Board convened a round-table discussion to explore recent developments, beginning with the revision of the submission guidelines. This discussion elaborates on the journal's role and its relevance to the academic community, including society members, authors, and readers. It features statements from participating editorial committee members and highlights the key issues discussed, including the criteria each member uses to evaluate manuscripts. The aim is to offer insight into the journal's editorial stance and decision-making process.

On 26 May 2024, the Panel Discussion 2 " Cooperation between medical doctors and acupuncturists: With a view to future medical care " was held at the 73rd Annual Meeting of the Japan Society of Acupuncture and Moxibustion was held in Sendai, Miyagi, Japan. Three panelists presented the attempts of cooperation between medical doctors and acupuncturists at medical institutions and medical field in Japan, including the fact that acupuncture and moxibustion have been successful in improving and alleviating patients' illnesses and symptoms in psychiatry, general internal medicine and palliative medicine, contributing to shorter hospital stays for patients, and the challenges for cooperation between medical doctors and acupuncturists at medical institutions and medical field in Japan. A designated speaker also presented on the development of highly specialized acupuncturists at the Japan Society of Acupuncture and Moxibustion to establish cooperation between medical doctors and acupuncturists, among others. Finally, we discussed issues and future prospects for cooperation between medical doctors and acupuncturists at medical institutions and medical field in Japan, with a view to future medical care where acupuncture and moxibustion will be utilized. One of the challenges in improving the utilization rate of acupuncture and moxibustion in Japan is the cooperation between medical doctors and acupuncturists at medical institutions and medical field. This report summarizes the contents of this panel discussion.

As part of U-40 activities, chapters have traditionally held sessions of lectures and hands-on as the Basic Lecture Course (BLC) to improve the basic skills and knowledge of young cardiovascular surgeons. Because of the COVID-19 epidemic, we have shifted our activities from onsite to online. This column focuses on “management of postoperative delirium and pain” in the lecture of “Postoperative Management in Cardiovascular Surgery” given by the Chubu Chapter in 2020. We summarize the lecture and report the results of a questionnaire survey of the U-40 members.

Background:
A supervised physiotherapy program (SPP) is a standard regimen after surgical rotator cuff repair (RCR); however, the effect of a home-based exercise program (HEP), as an alternative, on postoperative functional recovery remains unclear. Therefore, the purpose of this meta-analysis was to compare the functional effects of SPP and HEP after RCR.
Methods:
We searched electronic databases including Central, Medline, and Embase in April 2022. The primary outcomes included the Constant score, American Shoulder and Elbow Surgeons score, University of California Los Angeles shoulder score, and pain score. Secondary outcomes included range of motion, muscle strength, retear rate, and patient satisfaction rate. A meta-analysis using random-effects models was performed on the pooled results to determine the significance.
Results:
The initial database search yielded 848 records, five of which met our criteria. Variables at 3 months after surgery were successfully analyzed, including the Constant score (mean difference, −8.51 points; 95% confidence interval [CI], −32.72 to 15.69; P=0.49) and pain score (mean difference, 0.02 cm; 95% CI, −2.29 to 2.33; P=0.99). There were no significant differences between the SPP and HEP. Other variables were not analyzed owing to the lack of data.
Conclusions
Our data showed no significant differences between SSP and HEP with regard to the Constant and pain scores at 3 months after RCR. These results suggest that HEP may be an alternative regimen after RCR.Level of evidence: I.

Objective:
Coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was first reported in China and subsequently spread worldwide. In Japan, many clusters occurred during the first wave in 2020. We describe the investigation of an early outbreak in a Tokyo hospital.
Methods:
A COVID-19 outbreak occurred in two wards of the hospital from April to early May 2020. Confirmed cases were individuals with laboratory-confirmed SARS-CoV-2 infection linked to Wards A and B, and contacts were patients or workers in Wards A or B 2 weeks before the index cases developed symptoms. All contacts were tested, and cases were interviewed to determine the likely route of infection and inform the development of countermeasures to curb transmission.
Results:
There were 518 contacts, comprising 472 health-care workers (HCWs) and 46 patients, of whom 517 were tested. SARS-CoV-2 infection was confirmed in 42 individuals (30 HCWs and 12 patients). The proportions of SARS-CoV-2 infections in HCWs were highest among surgeons, nurses, nursing assistants and medical assistants. Several HCWs in these groups reported being in close proximity to one another while not wearing medical masks. Among HCWs, infection was thought to be associated with the use of a small break room and conference room.
Discussion
Nosocomial SARS-CoV-2 infections occurred in two wards of a Tokyo hospital, affecting HCWs and patients. Not wearing masks was considered a key risk factor for infection during this outbreak; masks are now a mandated countermeasure to prevent the spread of SARS-CoV-2 infection in hospital settings.
