Background: To evaluate the outcomes of conventional transarterial chemoembolization (TACE) using guidance software for hepatocellular carci-noma (HCC) in the caudate lobe.Methods: Seventy-two patients with 79 treatment-naïve caudate lobe HCCs were eligible. TACE was performed through feeders not only identified by automated tumor-feeder detection (AFD) functionality but also detected manually. Technical success of TACE was classified into three grades accord-ing to 1-week computed tomography findings: entire tumor embolized with a safety margin (5 mm for tumors < 25 mm and 10 mm for tumors ≥ 25 mm) (grade A); tumor embolized without a margin in parts (grade B); and entire tumor not embolized (grade C). Tumor response was evaluated using the modified Response Evaluation Criteria in Solid Tumors. Tumor-feeder detectability by AFD, technical success of TACE, complete response (CR) at 2–4 months, durable CR, and local tumor progression (LTP) rates calculated by the Kaplan-Meier method were compared in each tumor among three subsegments: the Spiegel lobe (SP); paracaval portion (PC); and caudate process (CP). LTP rates between the grade A and B tumors were also com-pared.Results: The mean tumor diameter was 18.6 ± 9.9 mm (range, 6–53 mm), and 111 of 129 (86.0%) tumor feeders were detected by AFD. The rates of feeder detectability by AFD, grade A technical success of TACE, CR at 2–4 months, and durable CR in 30 SP, 38 PC, and 11 CP tumors were 71.4%, 93.3%, 93.1%, and 79.3%; 94.8%, 65.8%, 59.4%, and 34.4%; and 76.5%, 63.6%, 80.0%, and 30.0%, respectively. LTP rates of SP tumors were sig-nificantly lower than those of PC tumors (P = 0.0044), and the grade B tumors progressed more frequently (P = 0.0012).Conclusion: AFD could detect 86.0% of tumor feeders in the caudate lobe; however, the feeder detectability, technical success of TACE, and outcomes differed among the three subsegments.

Background: In patients with distal malignant biliary obstruction, it is a challenge to manage acute cholecystitis secondary to cystic duct obstruc-tion associated with tumor progression or stent compression. Percutaneous transhepatic gallbladder drainage (PTGBD) has been used as the treatment option of choice, because of its ease of performance and safety, but because of the use of an external drainage tube, some patients experience a de-creased quality of life. We report the technical success and clinical success of conversion from PTGBD to endoscopic ultrasound-guided gallbladder drainage (EUS-GBD) for the treatment of acute cholecystitis in patients with unresectable malignant biliary obstruction.Methods: We included the patients with cholecystitis secondary to unresectable malignant biliary obstruction who underwent conversion from PT-GBD to EUS-GBD in the study. After PTGBD for the treatment of acute cholecystitis, we performed EUS-GBD and a plastic stent or a self-expandable metal stent (SEMS) was placed for fistulostomy.Results: Fourteen patients (median age, 69 years; 9 males and 5 females) underwent conversion to EUS-GBD after clinical improvement of cholecys-titis by PTGBD. The technical success rate of the conversion from PTGBD to EUS-GBD was 100% (14/14). EUS-GBD was performed in a median of 9.5 days (range, 3–51 days) after PTGBD procedure, using mainly a plastic stent (13 patients) and a covered SEMS in one patient. The early (within 24 hours) adverse events rate was 14.3% (2/14), and the late (after 24 hours) adverse events rate was 7.1% (1/14). The rate of recurrence of cholecystitis was 28.6% (4/14). These patients underwent endoscopic re-intervention and there were no cases of further recurrence of cholecystitis. Conclusion: Conversion of PTGBD to EUS-GBD demonstrated a feasible and safe technique for acute cholecystitis in non-surgical candidates with malignant biliary obstruction.
