Complete migration of a fully covered self-expandable metallic stent after endoscopic ultrasound-guided hepaticogastrostomy: A case report.

A male patient underwent gastrojejunal bypass surgery in 2017. In 2020, he was referred to our hospital for suspected obstructive jaundice. Subsequently, he was diagnosed with cholangiocarcinoma, and endoscopic retrograde cholangiopancreatography was attempted via balloon-assisted enteroscopy. However, the endoscope did not reach the duodenal papilla owing to the abdomen-small intestine adhesion. Therefore, endoscopic ultrasound-guided hepaticogastrostomy was performed using a dedicated plastic stent. After stent placement, obstructive jaundice and cholangitis promptly improved. However, we replaced the plastic stent with a fully covered self-expandable metal stent because stent occlusions occurred frequently. Two months after fully covered self-expandable metal stent placement, the patient developed cholangitis again. Notably, during the endoscopic procedure, the stent was found to be completely migrated. Nevertheless, the fistula was still open, and the patient was successfully retreated with the maintained fistula of endoscopic ultrasound-guided hepaticogastrostomy.

Fatal case of TAFRO syndrome with unilateral adrenal hemorrhage in early-stage disease.

Thrombocytopenia, anasarca, fever, reticulin fibrosis/renal failure, and organomegaly comprise TAFRO syndrome, which was proposed as a distinct clinical entity from iMCD without TAFRO syndrome (iMCD-NOS) due to its aggressive clinical course, refractoriness to corticosteroids, presence of thrombocytopenia, increased level of alkaline phosphatase, and normal level of gammaglobulin. However, diagnosing TAFRO syndrome in its early stages is challenging because it is rare and its diagnostic criteria are complicated. We describe a patient with TAFRO syndrome and adrenal hemorrhage who demonstrated a rapid decline in her clinical condition and did not respond to steroid pulse therapy, resulting in a fatal outcome. In the early stage of her clinical course, she developed unilateral adrenal hemorrhage with mild thrombocytopenia and normal clotting times, suggesting adrenal hemorrhage as a unique manifestation of TAFRO syndrome. In general, patients with TAFRO syndrome exhibit a more aggressive clinical course and poorer outcome than those with iMCD-NOS. To ameliorate this poor prognosis, it is important to diagnose the disease early and immediately start powerful immunosuppressive agents such as tocilizumab. Based on this case, adrenal hemorrhage may suggest TAFRO syndrome, and facilitate the rapid diagnosis of this complicated and rare disease.
