Outcomes of Endoscopic Ultrasound-Guided Biliary Drainage in Patients Undergoing Antithrombotic Therapy

Background/Aims@#The Japan Gastroenterological Endoscopy Society (JGES) has published guidelines for gastroenterological endoscopy in patients undergoing antithrombotic treatment. These guidelines classify endoscopic ultrasound-guided biliary drainage (EUS-BD) as a high-risk procedure. Nevertheless, the bleeding risk of EUS-BD in patients undergoing antithrombotic therapy is uncertain. Therefore, this study aimed to assess the bleeding risk in patients undergoing antithrombotic therapy. @*Methods@#This single-center retrospective study included 220 consecutive patients who underwent EUS-BD between January 2013 and December 2018. We managed the withdrawal and continuation of antithrombotic agents according to the JGES guidelines. We compared the bleeding event rates among patients who received and those who did not receive antithrombotic agents. @*Results@#A total of 18 patients (8.1%) received antithrombotic agents and 202 patients (91.8%) did not. Three patients experienced bleeding events, with an overall bleeding event rate of 1.3% (3/220): one patient was in the antithrombotic group (5.5%) and two patients were in the non-antithrombotic group (0.9%) (p=0.10). All cases were moderate. The sole thromboembolic event (0.4%) was a cerebral infarction in a patient in the non-antithrombotic group. @*Conclusions@#The rate of EUS-BD-related bleeding events was low. Even in patients receiving antithrombotic therapy, the bleeding event rates were not significantly different from those in patients not receiving antithrombotic therapy.

Infectious peritonitis after endoscopic ultrasound-guided biliary drainage in a patient with ascites

SUMMARY OF EVENT: Bacterial, mycotic peritonitis and Candida fungemia developed in a patient with moderate ascites who had undergone endoscopic ultrasound-guided biliary drainage (EUS-BD). Antibiotics and antifungal agent were administered and ascites drainage was performed. Although the infection improved, the patient's general condition gradually deteriorated due to aggravation of the primary cancer and he died. TEACHING POINT: This is the first report to describe infectious peritonitis after EUS-BD. Ascites carries the potential risk of severe complications. As such, in patients with ascites, endoscopic retrograde cholangiopancreatography (ERCP) is typically preferred over EUS-BD or percutaneous drainage to prevent bile leakage. However, ERCP may not be possible in some patients with tumor invasion of the duodenum or with surgically altered anatomy. Thus, in patients with ascites who require EUS-BD, we recommend inserting the drainage tube percutaneously and draining the ascites before and after the intervention in order to prevent severe infection.

Risks of transesophageal endoscopic ultrasonography-guided biliary drainage

SUMMARY OF EVENT: Pneumoderma, mediastinal emphysema, and bilateral pneumothorax were developed in the patient who had undergone transesophageal endoscopic ultrasonography-guided rendezvous technique. Chest drainage was performed immediately. TEACHING POINT: Transesophageal approach carries the potential risks of severe complications such as mediastinal emphysema, mediastinitis, and pneumothorax. To prevent puncturing through the esophagus, clipping the esophagogastric junction using a forward-viewing scope before procedure is very useful. In cases of inadvertent transesophageal puncture, devices other than the needle should not be passed through the site.

Chuno Kosei Hospital and Community Medicine / 日本農村医学会雑誌

  Chuno Kosei Hospital is located in Seki City, 15 kilometers east of Gifu City. The area served by the hospital has a population of about 150,000. We have 19 medical care departments, 383 beds and a staff of 537, including 74 physicians and 319 nurses.<br>  The hospital was founded in January, 1948 with 37 beds. Since then, through enrichment of functions and expansion of the wards, the institution went on to become what could be called a citizens' hospital of Seki and in fact, has played the role of a community-core hospital in Seki City and its environs. In 2000, the hospital moved to the present site for improvement of medical standards and the Emergency Medical Center was set up simultaneously.<br>  At present, our hospital is rendering great services to various medical fields (high quality medicine, emergency medical care, health checkup service, delivery of medicine in remote regions, organization of DMAT, education of clinical residents etc.) in this area.<br>  In the future, we need to be in more close connection and collaboration with adjacent hospitals and clinics for medical and health care for the inhabitants.<br>  We will do our best to protect people's health and life, keeping in mind the concept of the hospital: peace of mind for patients, confidence in community, hope for tomorrow. For realization of our concept, we have adopted three fundamental policies: improvement of medical quality, elevation of staff education and stabilization of hospital management. In these policies, I believe the greatest emphasis policy should be placed on staff education.
