Abstract

Advanced pancreatic head cancer with tumor infiltration into the duodenum is capable of distorting the anatomy and is extremely challenging for selective biliary cannulation during ERCP. In these situations, the ERCP–PTBD rendezvous method served as a valuable alternative. Therefore, this case report aimed to describe the case of a 75-year-old man who presented with obstructive jaundice. On examination, the patient was tachycardic and febrile (38.0°C), with pale conjunctivae and marked scleral icterus. A palpable mass was observed in the epigastric region, and laboratory evaluation showed a total bilirubin level of 18.64 mg/dL. Furthermore, MRCP showed a mass in the pancreatic head infiltrating the duodenum, leading to significant intra- and extrahepatic biliary dilatation. The patient was initially subjected to transhepatic biliary drainage (PTBD), followed by an ERCP using the rendezvous method due to the tumor-related distortion of the papilla. During this procedure, a guidewire was advanced through the PTBD tract and navigated under fluoroscopy into the duodenum, facilitating biliary access and successful placement of a biliary stent. Two days after the intervention, the condition improved, with bilirubin decreasing to 8.91 mg/dL, and the patient was subsequently discharged in stable condition. This case showed the rendezvous method as an effective alternative biliary drainage strategy for patients in whom conventional ERCP was hindered by tumor-related anatomical alterations.

Abstract

Background: Abdominal ultrasound is an essential competency for internists, although traditional workshop often lack structured learning strategies and measurable skill outcomes. To address this limitation, mastery learning offers deliberate practice, standardized assessment, and competency-based progression. However, the use of mastery learning in abdominal ultrasound training for internists remains limited. Therefore, this study aimed to evaluate the feasibility and effectiveness of applying mastery learning principles within a point-of-care basic upper abdominal ultrasound workshop designed for internists. Methods: A prospective study was conducted during the JIMDACE 2025 upper abdominal ultrasound workshop. Participants were subjected to pre- and post-training assessments across six targeted skills using a standardized checklist based on the Expert Performance Method. Subsequently, real-time feedback was provided during hands-on sessions. The scores obtained were analyzed using the Wilcoxon signed-rank test, followed by the calculation of effect size. Results: The results showed that the total scores of all 13 participants included in the final analysis improved from 1.750 (±1.571) at pre-test to 5 (range 0–6) at post-test. Furthermore, significant improvements were observed overall (p=0.001). Conclusion: The mastery learning-based workshop significantly improved abdominal ultrasound competence among internists, showing feasibility and strong educational impact. This method showed potential as a foundation for future structured ultrasound training programs.

Abstract

The management of ulcerative colitis is primarily focused on the prevention of complications, remission sustenance, and enhancement of overall quality of life. However, long-term use of various pharmacological therapies can be associated with several side effects, including myelosuppression, hepatitis, lupus-like syndrome, and an increased risk of malignancy. These limitations have led to the search for safer therapeutic options, including bioactive compounds such as Beta-1,3/1,6-D-Glucan with immunomodulatory properties. Ganoderma lucidum contains Beta-1,3/1,6-D-Glucan as a principal bioactive compound extracted from its mycelium. Despite the broad therapeutic properties, exploration into its role specifically for ulcerative colitis patients remains scarce. Therefore, this case series aimed to explore the potential role of Beta-1,3/1,6-D-Glucan derived from Mycelium extract of Ganoderma lucidum in managing ulcerative colitis.
