Résumé

BACKGROUND/AIMS: To retrospectively compare conventional and drug-eluting beads transarterial chemoembolization (C-TACE and DEB-TACE) for treatment of hepatocellular carcinoma (HCC) at very early and early stages. METHODS: We retrospectively compared patients treated with C-TACE (n=115) or DEB-TACE (n=103) from September 2009 to May 2016. All patients were in a very early (stage 0) or early stage (stage A) of the Barcelona Clinic Liver Cancer (BCLC) staging system, and all had Child–Pugh class A and ≤B7 liver status. Approval by the institutional review board was waived because the study was retrospective. The following parameters were evaluated: severe pain and bradycardia during TACE, post-embolization syndrome (PES), liver function change, complications, target tumor response, and conversion to another treatment modality. Numeric differences were assessed by the independent Student's t-test for continuous variables and by chi-square test for categorical variables. RESULTS: Severe intractable pain and bradycardia during the TACE procedure were significantly more frequent in the C-TACE group than in the DEB-TACE group (P<0.001). The incidence and duration of PES were significantly higher in the C-TACE group than in the DEB-TACE group (P<0.001). The increase in liver enzymes was significantly higher in the C-TACE group than in the DEB-TACE group (P<0.001). The deterioration of the Child-Pugh class was significantly higher in the C-TACE group than in the DEB-TACE group (P =0.006). There was no significant difference in serious complications except localized bile duct dilatation between the groups. There was no significant difference between the groups in tumor response at both immediate and 1-year assessment. The conversion rate to other treatment modalities was significantly higher in the DEB-TACE group than in the C-TACE group (P<0.001). CONCLUSIONS: DEB-TACE is better than C-TACE in terms of procedural safety as initial treatment in a very early or early stage of HCC.

Résumé

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 with a small-bore (11- or 13-Fr) catheter was inserted under bi-plane fluoroscopic assistance. RESULTS: Technical success was achieved in all patients. Complete lung re-expansion was achieved at 24 hours in 88.9% of patients (16/18 patients). All patients tolerated the procedure and no major complications occurred. The patients' mean numeric pain intensity score was 2.4 (range: 0–5) in daily life activity during the TV treatment. All patients with spontaneous pneumothorax underwent outpatient follow-up. The mean time to TV removal was 4.7 (3–13) days. Early surgical conversion rate of 16.7% (3/18 patients) occurred in 2 patients with incomplete lung expansion and 1 patient with immediate pneumothorax recurrence post-TV removal; and late surgical conversion occurred in 2 of 18 patients (11.1%). The recurrence-free long-term success rate was 72.2% (13/18 patients) during a 3-year follow-up period from November 2012 to June 2016. CONCLUSION: TV application was a simple, safe, and technically feasible procedure in an outpatient clinic, with an acceptable long-term recurrence-free rate. Thus, TV could be useful for the immediate treatment of pneumothorax.

Résumé

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 CBCTA were systematically performed and analyzed. Three settings of the FPFL software for vascular tree segmentation were tested for each tumor: the default, Group D; adjusting the proportion of segmented tumor area between 30 to 50%, Group L; and between 50 to 80%, Group H. RESULTS: In total, 109 feeder vessels supplying 80 HCC nodules were identified. The negative predictive value of DSA, FPFL in groups D, L, and H was 56.8%, 87.7%, 94.2%, 98.5%, respectively. The accuracy of DSA, FPFL in groups D, L, and H was 62.6%, 86.8%, 93.4%, 95.6%, respectively. The sensitivity, negative predictive value (NPV), and accuracy of FPFL were higher in Group H than in Group D (p = 0.041, 0.034, 0.005). All three segmentation sensitivity groups showed higher specificity, positive predictive value, NPV, and accuracy of FPFL, as compared to DSA. CONCLUSION: FlightPlan for Liver is a valuable tool for increasing detection of HCC tumor feeding vessels, as compared to standard DSA analysis, particularly in small HCC. Manual adjustment of segmentation sensitivity improves the accuracy of FPFL.

Résumé

Multiple endocrine neoplasia type 1 (MEN1) is an autosomal dominant inherited syndrome with characteristic clinical and radiological manifestations. Many reports on MEN1 have been published; however, no cases of radiologically diagnosed MEN1 have been reported. Therefore, we report on a radiologically diagnosed case of MEN1 with clinical symptoms of gastroduodenal ulcer.

Résumé

Perinatal detection of neonatal suprarenal masses has increased. Here, we report an unusual case of an adrenal cystic neuroblastoma that presented as a purely cystic lesion upon initial postnatal ultrasonography (US) and showed rapid evolution to a mixed cystic and solid mass during follow-up US and MRI. We suggest a short-term (two weeks) follow-up US for neonatal adrenal cystic lesions, even if they appear as purely cystic.
