The authors present their US findings in 24 patients with proved complicated midgut malrotation: volvulus in 18 and occlusive Ladd's bands in 6. All the 24 patients have had US examination prior to surgery. Contrast examinations were performed in only 9 patients, always after US and before surgery. The sonographic "whirlpool" pattern of the superior mesenteric vein and mesentery around the superior mesenteric artery was detected in 15 of the 18 patients with midgut volvulus, and was best seen using Doppler color. Embryological signification of midgut malrotation is discussed.
Self-expanding, metal biliary stents have recently been used in malignant obstructive jaundice as their large diameter reduces the likelihood of occlusion by biliary sludge and bacterial biofilm. However, there is a significant rate of late obstruction by tumour overgrowth and infiltration through the wire mesh. Our case of stent erosion through the duodenal wall, resulting in massive haemorrhage, is a hitherto unreported serious complication of the Wallstent (Schneider). Its occurrence may be suggested by continuous upper abdominal pain, gastrointestinal bleeding or late expansion of the stent.
