• DWI is now being used to assess many cancers. • Change in ADC measurements offer new information about oesophageal tumours. • ADC changes are more reliable than dimensional criteria in assessing neoadjuvant treatment. • Such ADC assessment could optimise management of locally advanced gastro-oesophageal cancers.

SG of VAAs and VAPAs was safe and effective, particularly in elective treatments. The Viabahn stent-graft, flexible and without shape memory, is suitable for endovascular repair of tortuous visceral arteries.

In endovascular treatment of visceral aneurysms, covered stenting was feasible in 30%. CS showed a slightly better efficacy than TE and good midterm patency. The Viabahn covered stent seems to be suitable for endovascular repair of tortuous visceral arteries affected by true or false aneurysms.

OBJECTIVES: To observe the evolution of intraabdominal adipose tissue (IAT) in obese prepubertal children, who did not change their degree of obesity during adolescence and to evaluate its relationship with metabolic risk indexes (RI). DESIGN: Longitudinal study of 16 obese adolescents (eight male and eight female) in whom relative body weight (RBW) did not change signi®cantly and pubertal development was completed during the study period. MEASUREMENTS: Magnetic resonance imaging (MRI) scan at lumbar level (L4) three times during a 4 y period. At basal and at four years biochemical assays for metabolic indexes. RESULTS: IAT did not differ signi®cantly over the three measurement times and showed signi®cant correlations between ®rst and second (r 0.66, P`0.005), ®rst and third (r 0.61, P`0.01) and second and third values (r 0.84, P`0.0001). Subcutaneous adipose tissue (SAT) increased signi®cantly from basal to third evaluation (P`0.002). At baseline, IAT correlated signi®cantly with lipids (total and LDL cholesterol r 0.72, P`0.004), while at the end of the study, IAT correlated positively with insulin (fasting insulin r 0.55, P`0.008, insulin area after oral glucose tolerance test (OGTT) r 0.60, P`0.03, fasting insulinaglucose r 0.67 P`0.006) and negatively with high density lipoprotein (HDL) cholesterol (r 7 0.55, P`0.04). CONCLUSIONS: Obesity achieved before puberty, and stable during adolescence, showed a relatively stable amount of IAT. In post pubertal children the relationship of IAT to clinically signi®cant risk factors resemble the pattern in obese adults.
