PURPOSE: To assess the role and efficacy of radiologic intervention in the adult patients with esophagobronchial fistula. MATERIALS AND METHODS: Radiologic intervertion was performed in 4 patients with esophagobronchial fistula. We tried direct occlusion of fistula tract by glue(histoacylate 0.4cc + lipiodol 0.3cc) and coil in 2 patients and performed presurgical wire insertion by using 8F curved catheter via esophageal opening of fistula tract. The latter procedure was carled out to detect the fistula tract easily at operation. RESULTS: Direct occlusions of fistula tract by glue and coil were performed only to fail in 2 patients. Pre-surgical wire incertion by using 8F curred catheter under guidance of fluroscopy in 3 patients were helpful in detecting fistula tract at operation. CONCLUSION: Direct occlusion of the fistulous tract in esophagobronchial fistulas was ineffective. However, presur- gical wire insertion by using cured catheter under fluroscopy guidance is helpful to detect the fistula tract easily at operation.

Lipiodol based conventional transarterial chemoembolization (TACE) is a standard of care for unresectable, non-invasive, and multinodular Hepatocellular carcinoma (HCC)s. The procedure relies on the intra-arterial administration of lipiodol/cytotoxic agent emulsion followed by the infusion of embolic material. Lipiodol, with its oily nature and radiopacifying properties, is in the center of the TACE procedure. Unstability and unpredictable therapeutic effect of hydrophilic cytotoxic drugs emulsified in the lipiodol and technical problems lie beyond the control of clinicians. Thus, interest in the properties and respective roles for lipiodol in the management of HCC is essential for the clinicians.

Inflammatory myofibroblastic tumor (IMT) of the liver is a very rare lesion that has radiologic similarity with malignant liver tumor. Differential diagnosis of IMT from a malignant lesion of the liver is very important because surgical resection is not mandatory for IMT. Lipiodol computed tomography is a very sensitive and specific diagnostic tool for hepatocellular carcinomas (HCC). Herein, we describe a case of IMT that had dense lipiodol uptake in the tumor and mimicked HCC. To our knowledge, previously, only one case of IMT with dense lipiodol retention has been reported.

PURPOSE: To assess the diagnostic accuracy of dual-phase computed tomography during hepaticarteriography(CTHA) in depicting hypervascular hepatocellular carcinoma. MATERIALS AND METHODS: Forty patientswith hepatocellular carcinoma underwent dual-phase CTHA. First-phase data was obtained 6 seconds after contrastmedia was injected into the common hepatic artery, while second-phase data was obtained 35-40 seconds later.Lipiodol CT was performed 10-17 days after 2mL of lipiodol was injected into the proper hepatic artery. As agold-standard of 172 lipiodol-uptaken nodules seen on lipiodol CT, the detectability and positive predictive valueof the first and second phases, and the simultaneous interpretation of both phases, were analysed. RESULTS: Allnodules were detected by first-phase CTHA, 162 (94%) by second-phase CTHA, and 170 (99%) by simultaneousinterpretation of both phases. The detection sensitivities of first-phase CTHA and simultaneous interpretation ofboth phases were statistically superior to that of second-phase CTHA. Positive predictive values were 87% withfirst-phase CTHA, 96% with second-phase CTHA, and 97% with simultaneous interpretation of both phases. CONCLUSION: Dual-phase CTHA was useful for increasing detectability and accuracy in the diagnosis of hypervascularhepatocellular carcinoma.

PURPOSE: To evaluate the effectiveness of transcatheter arterial chemoembolization(TACE) as a preoperative treatment for initially unresectable hepatoblastomas. METHODS: From January 1995 to July 1999, we identified two boys and three girls(age range: 5- 27 months; mean age: 12 months) with pathologically-confirmed hepatoblastoma. To assess response to treatment, we utilized an identical TACE procedure for all the patients. A second TACE procedure was performed 3 weeks after the first TACE procedure and patients underwent tumor resection approximately 1 month following the second TACE procedure. The therapeutic responses to TACE were assessed by measuring of tumor size, shape, observation of tumor properties using abdominal computed tomography(CT), gross and microscopic pathologic findings, levels of alpha- feto protein(AFP) and clinical adverse events to TACE. RESULTS: In these patients, hepatoblastomas showed marked reductions in tumor size. Massive tumor necrosis and homogeneous distribution of lipiodol created a clear margin bordered by surrounding normal liver tissue. At initial diagnosis, the mean AFP leve1=867Ang/mL, 47.4ng/mL after second TACE, and 8.6ng/mL at 6 months after surgical resection. Transient fever was ob- served following TACE and elevations of levels of AST and ALT were observed but these normalized 2 weeks following TACE. No major complications were associated with TACE. CONCLUSION: We suggest that preoperative TACE is an effective, safe, and useful method for patients with initially unresectable hepatoblastoma.

Seventeen cases of chronic dacryocystitis were studied by performing dacryocystography, using Pantepaque or Lipiodol as the dye. The youngest patient was 22 years of age, the oldest 66 years. Two cases were in male sex and remaining twelve were in females. Of these 17 cases, the chronic dacryocystitis was present on both sides in ten cases, on the right side in 4 and on the left side in 3. Daryocystograms showed that: 1. The most common site of obstruction was the neck of the sac(61.5%). 2. The obstruction was total and complete, except one case. 3. The lacrimal sac shown by dacryocystography as follows: a) a large sac with atony suggesting several years of suppurative inflammation. b) a samll shrunken sac suggesting several years of mild inflammation. c) normal sized sac with irregular outline suggesting recent acute exacervation of the disease. d) normal sized sac suggesting short duration of chronic mild inflammation. 4. Two cases of fistula and one case of diverticulum were observed. 5. There were nonvisualization of five cases of the lacrimal sac because of obstruction of canaliculi or ampulla.

Transcatheter arterial chemoembolization (TACE) is one of the most common palliative treatment modalities for patients with advanced hepatocellular carcinoma (HCC). TACE is an invasive procedure associated with several potential complications of varying severity. A pulmonary embolism after TACE for HCC is a rare complication. We report a case of pulmonary Lipiodol embolism after a third TACE resulting in death.

PURPOSE: To assess the malignant potential of small(< or =15mm) portal defects seen on CT arterial portography,the findings of CT hepatic arteriography and lipiodol CT CT were reviewed. MATERIALS AND METHODS: In 91 patientswho underwent both CTAP and CTHA, small portal defects were re-viewed for frequency, multiplicity and location. Weprospectively evauluated changes in the size and enhance-ment pattern of malignant lesions on follow up CTaccording to density on CTHA, location, lipiodol deposits on lipiodol CT, and multiplicity. RESULTS: Among the 91patients, 102 small defects were defected in 42 patients(46%). Small portal defects were benign, malignant, and ofundetermined malignant potential in 77%, 20% and 3% of cases, respectively. Small portal defects that werehyperattenuated on CTHA, and lipiodol deposits on lipiodol CT, were malignant in 42% and 70% of cases,respectively. Location and multiplicity did not show statistically significant variation between benign andmalignant defects. CONCLUSION: Small portal defects are common and there is a high probability that portaldefects smaller than 15mm are benign, even in patients with a known hepatic mass and defect that washyperattenuated on CTHA. If a small defect showed lipiodol deposit on lipiodol CT, malignancy must be suspected.
