ABSTRACT
INTRODUCTION: Superior mesenteric artery syndrome is a rare condition characterised by nausea, vomiting, postprandial pain, anorexia and early satiety. Conservative management is tried initially, but if this fails, surgery is indicated. There are few reports in the literature concerning superior mesenteric artery syndrome in children, and fewer still managed surgically by minimally invasive means. CASE PRESENTATION: A 12-year-old girl presented with weight loss, early satiety and vomiting after corrective scoliosis surgery. After upper gastrointestinal endoscopy, contrast study and computed tomography imaging, a diagnosis of superior mesenteric artery syndrome was made. Conservative management by nasojejunal feeding failed; therefore, a laparoscopic duodeno-jejunostomy was undertaken. At follow-up, her symptoms had improved. CONCLUSION: This report describes the youngest child to undergo laparoscopic duodeno-jejunostomy for superior mesenteric artery syndrome. Laparoscopic duodeno-jejunostomy appears to be the most widely employed and reliable minimally invasive approach to superior mesenteric artery syndrome with a high success rate and acceptably low complication rate.

Aneurysmal dilation of arteriovenous fistulae used for haemodialysis is a recognised complication but its clinical significance is a contentious issue. Our aims were to describe aneurysmal fistulae morphologically and clinically.Sixty patients underwent duplex scanning to measure the maximum diameter and skin thickness of their fistula. Haemodialysis function and bleeding risk were assessed clinically.The 75th percentile of maximum diameter was 2.05 cm. In addition to conventional diameter measurement, we describe a novel volume measurement technique which may be of value. No relationship was found between maximum diameter or volume and function, skin thickness or bleeding.Some studies define aneurysm at 2 cm (75th percentile); however, this definition and other arbitrary definitions lack clinical significance. This work suggests that fistula dilation should be considered together with clinical issues when determining the clinical significance of an aneurysm. Our finding that haemodialysis function, skin thickness and bleeding were not associated with diameter needs further study.
