OBJECTIVE: The purpose of this study was to clarify the frequency of and risk factors for liver abscess formation after transarterial chemoembolization (TACE) in patients with hepatocellular carcinoma or metastatic hepatic tumors after undergoing bilioenteric anastomosis. MATERIALS AND METHODS: From January 1996 to June 2012, 25 patients (21 men, four women; age range, 34-74 years) with hepatocellular carcinoma (n = 12) or metastatic hepatic tumors (n = 13) with an underlying bilioenteric anasto

Most normal appendices are visualized on thin-section LD unenhanced CT images reviewed with the sliding slab averaging technique.

BACKGROUND: Recently, there has been an increase in clinical success rates using nonsurgical methods to resolve anastomotic biliary strictures (ABSs) that develop after liver transplantation (LT). However, some strictures are particularly refractory and cannot be completely resolved by an endoscopic or percutaneous procedure. Consequently, the aim of this study was to examine the feasibility and efficacy of using a newly designed fully covered self-expandable metal stent (FCSEMS) to resolve refr

OBJECTIVE: To evaluate retrospectively the clinical effectiveness of FlightPlan for Liver (FPFL), an automated tumor-feeding artery detection software in cone-beam CT angiography (CBCTA), in identifying tumor-feeding arteries for the treatment of hepatocellular carcinoma (HCC) using three different segmentation sensitivities. MATERIALS AND METHODS: The study included 50 patients with 80 HCC nodules who received transarterial chemoembolization. Standard digital subtracted angiography (DSA) and CB

DEE chemoembolization for nodular HCCs in the Korean population showed acceptable survival, tumor response, and safety profiles after a two-year follow-up. Good liver function (Child-Pugh score A5) was a key predictor of per-patient OS, PFS, and per-lesion tumor control.

FCSEMSs have an efficacy and safety similar to those of PTCS catheters for maintaining biliary tract patency after MCA, but are more convenient for patients.

OBJECTIVES: Non-surgical methods have high success rates for treating benign biliary strictures (BBSs), but treatment of proximal strictures is difficult. Recent studies have reported that fully covered self-expandable metal stents (FCSEMSs) are useful for treating refractory BBSs. We investigated the efficacy of a short and removable FCSEMS with an anti-migration design for treatment of proximal BBSs. METHODS: Fully covered self-expandable metal stents were inserted endoscopically in patients w

Postcholecystectomy biliary stricture can be treated with endoscopic or percutaneous treatments. However, these conventional methods are not feasible if a guidewire cannot be passed through the stricture.1-6 We report magnetic compression anastomosis for the treatment of a biliary stricture after cholecystectomy that could not be treated with conventional methods (Video 1, available online at www.VideoGIE.org).

OBJECTIVE: This study aimed to assess the technical feasibility, procedural safety, and long-term therapeutic efficacy of a small-sized ambulatory thoracic vent (TV) device for the treatment of pneumothorax. MATERIALS AND METHODS: From November 2012 to July 2013, 18 consecutive patients (3 females, 15 males) aged 16-64 years (mean: 34.7 ± 14.9 years, median: 29 years) were enrolled prospectively. Of these, 15 patients had spontaneous pneumothorax and 3 had iatrogenic pneumothorax. A Tru-Close TV

Computed tomography lymphography using ethiodized oil may be feasible for sentinel node mapping in experimentally induced VX2 carcinoma in the rabbit thigh.

Concurrent intra-arterial chemotherapy and radiotherapy (iA-CCRT) can increase the response rate in hepatocellular carcinoma (HCC), but may cause a higher toxicity. We conducted this Phase I study to investigate the dose-limiting toxicity of iA-CCRT for HCC. In total, 52.5 Gy in 25 fractions was prescribed as planning target volume (PTV) 1 at dose level 1. The dose escalation was 0.2 Gy per fraction and up to 2.5 Gy, with 62.5 Gy at level 3. Concurrent intra-arterial 5-fluorouracil was administe
