<p><b>Objective:</b> Bile duct tumor thrombosis in hepatocellular carcinoma (HCC) is a relatively rare event with a poor prognosis. Furthermore, bile duct tumor thrombus in HCC may be misdiagnosed when only imaging modalities are used. The efficiency of peroral cholangioscopy (POCS) in evaluating bile duct lesions has been reported.</p><p><b>Patients:</b> We present three cases of HCC with bile duct strictures in which POCS was performed as a preoperative evaluation.</p><p><b>Results:</b> In these three cases, diagnosing whether the lesion was a bile duct tumor thrombus on CT and endoscopic retrograde cholangiopancreatography was difficult. We performed POCS in three cases and were able to diagnose the presence of bile duct tumor thrombus of HCC, including differentiation from extrinsic compression of the bile duct.</p><p><b>Conclusion:</b> POCS for HCC with bile duct features is useful for the preoperative diagnosis of bile duct tumor thrombus, especially in cases where the surgical procedure depends on the presence of bile duct tumor thrombus.</p>

<p>Primary cystic duct carcinoma is a rare tumor. The curative treatment of cystic duct carcinoma is complete surgical resection, for which the evaluation of local extension is important. We herein report two cases of cystic duct carcinoma in which a preoperative examination was performed using per-oral cholangioscopy (POCS). Both patients underwent POCS due to suspicion of cystic duct carcinoma based on imaging findings. A visual analysis and biopsy were performed to evaluate local extension, which led to surgery. These cases suggest that POCS is useful for the preoperative assessment of local extension in advanced cystic duct carcinoma. </p>

<p>We herein report a case of recurrence of epithelial ovarian carcinoma 41 years after the primary surgery that was diagnosed by an endoscopic ultrasound-guided fine-needle biopsy (EUS-FNB). The differential diagnosis based on the imaging findings was difficult. We performed an EUS-FNB and compared the EUS-FNB specimen to the surgical specimen that had been resected in the primary surgery for ovarian carcinoma 41 years earlier, including immunohistochemical staining. Finally, we made a definitive diagnosis of extremely late recurrence of ovarian carcinoma of the retroperitoneum. An EUS-FNB enables an accurate histological diagnosis by obtaining a sample that is large enough to perform immunohistochemical staining. </p>

<p>Splenic sarcoidosis is often diagnosed by splenectomy or an ultrasound-guided splenic biopsy. However, splenectomy is invasive and costly, and a percutaneous biopsy is sometimes difficult. We herein report a case of splenic sarcoidosis diagnosed with endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA). A 71-year-old man was referred to our hospital for abnormal shadows on a chest roentgenogram. Computed tomography showed multiple lesions in the spleen and pulmonary consolidations. Bronchoscopy revealed no definitive diagnosis. We therefore performed EUS-FNA for a splenic lesion that led to the diagnosis. This case suggests that EUS-FNA is useful in confirming the diagnosis of sarcoidosis with suspected splenic lesions. </p>
