For Choledochal cyst type I, complete excision of cyst with Roux-en-Y hepaticojejunostomy anastomosis is the treatment of choice. It has been performed laparoscopically with the advancement of laparoscopic skill. Recently, a telemanipulative robotic surgical system was introduced, providing laparoscopic instruments with wrist-arm technology and 3-dimensional visualization of the operative field...

A 65-year-old woman developed chronic renal failure of unknown etiology and required hemodialysis. She was scheduled to undergo living-related renal transplantation from her husband. However, a cystic lesion of the liver associated with calcification, gallstones, and dilatation of intrahepatic bile ducts (B2-B3) was found by the referring hospital. Investigation of the cystic tumor was performe...

OBJECTIVE To evaluate the effect of the heat-sink phenomenon induced by artificial ascites on the size of the ablation zone during percutaneous radiofrequency (RF) ablation of the hepatic subcapsular area in an in vivo rabbit model. MATERIALS AND METHODS A total of 21 percutaneous rabbit liver RF ablations were performed with and without artificial ascites (5% dextrose aqueous solution). The ...

Radiofrequency ablation (RFA) using a percutaneous catheter is a common approach to treat supraventricular arrhythmias. Atrial fibrillation (AF) frequently arises from an abnormal focus at or near the junction of the pulmonary veins and the left atrium, thus leading to the feasibility of more focused ablation techniques directed at these structures. Catheter-based ablation, using RFA or cryoabl...

INTRODUCTION Percutaneous catheter ablation for atrial fibrillation (AF) is a procedure performed typically in an inpatient setting. The feasibility and safety of catheter ablation in patients with paroxysmal and persistent AF were evaluated on an outpatient basis. METHODS 230 AF ablation procedures were performed in 206 patients (74% male; mean age 56+/-9 years). Patients were admitted to th...

Renal Cell Carcinoma (RCC) is a common renal parenchymal malignancy. Although complete or partial nephrectomy is still the gold standard of management, a lot of minimally invasive techniques are currently emerging into the field of treatment. Recently, image-guided radiofrequency (RF) ablation has received increasing attention and been proposed as an alternation to more invasive procedures such...

A 30-year-old male with cerebral palsy and motor impairment presented with right femur fracture. He had gradually worsening mobility and contractures of all extremities for the preceding 5 years. Evaluation showed multiple vertebral and femoral fractures, severe osteoporosis, a large parathyroid adenoma, and parathormone (PTH) exceeding 2500 pg/mL. Because of poor general health and high anesth...

BACKGROUND Image-guided percutaneous thermal ablation is a commonly performed therapeutic procedure for various tumors. Thermal ablation is not frequently used in the pelvis as a result of anatomic concerns and the potential risk of nontarget tissue injury. TECHNIQUE Percutaneous thermal ablation is a minimally invasive procedure involving special probes inserted through the skin to the targe...

BACKGROUND Accumulating evidences have suggested that percutaneous cryoablation could be a valuable alternative ablation therapy for HCC but there has been no large cohort-based analysis on its long-term outcomes. METHODS A series of 866 patients with Child-Pugh class A-B cirrhosis and HCC within Milan criteria who underwent percutaneous cryoablation was long-term followed. The safety, effica...
