A total 2525 subjects were investigated based on endoscopic findings questionnaires with Rome III criteria, Helicobacter pylori serology (IgG).A 1714...
EUS-guided biliary drainage (EUS-BD) is a feasible procedure when ERCP fails, as percutaneous transhepatic BD (PTBD). However, little known about patient perception and preference of EUS-BD PTBD.An international multicenter survey was conducted in seven tertiary referral centers. In total, 327 patients, scheduled to undergo for suspected malignant obstruction, were enrolled the study. Patients received decision aids with visual representation regarding techniques, benefits, adverse events...
Acute mesenteric ischemia occurs mainly in elderly individuals; however, it can also affect young adults, and some of these patients experience a poor disease course because delayed diagnosis treatment. This study aimed to assess the clinical characteristics outcomes adults with acute ischemia. We retrospectively reviewed adult aged 20 39 years diagnosed between 2002 2022 at four tertiary medical centers Korea. Their were compared those middle-aged 40 49 years. A total 86 included. The...
Endoscopic snare papillectomy (ESP) is an effective treatment for ampullary adenoma. Argon plasma coagulation (APC) widely used as additional method to control bleeding or ablate the residual tumor. However, efficacy of this procedure has not yet been fully evaluated. This study aimed evaluate usefulness APC ESP.Patients who underwent ESP adenoma between September 2005 and 2015 were retrospectively reviewed. Using propensity score matching, we compared short- long-term outcomes...

Abstract Background and Aim Little is known whether routine prophylaxis against Pneumocystis jirovecii pneumonia (PJP) needed in patients with inflammatory bowel disease (IBD) on immunosuppression, especially Asian populations. We, therefore, sought to investigate the incidence risk factors of PJP IBD Korea. Methods We investigated compared characteristics episodes (IBD‐PJP group) those matched controls (IBD‐only using a large, well‐characterized referral center‐based cohort. Results Among...
Background Some biliary complications after liver transplantation (LT) are difficult to manage by endoscopic or radiologic intervention alone. In these cases, percutaneous transhepatic cholangioscopy (PTCS) can be used as an adjuvant option. Methods Patients who underwent PTCS for post-LT between August 1992 and January 2016 were retrospectively reviewed. Results Fifteen patients complications. The median age at LT was 47 years 11 male. Indications follows: decompensated cirrhosis (n = 9),...
