The treatment of Legg-Calvé-Perthes disease remains controversial. The aim of this survey was to ascertain the current management
strategies of this condition amongst UK paediatric orthopaedic surgeons, with particular regard to containment procedures
in the fragmentation phase. Questionnaires were distributed at the January 2006 meeting of the British Society for Children’s
Orthopaedic Surgery (BSCOS) and was posted to all absent members. The results showed a great deal of variability not only
in the treatment of Perthes disease, but also in the decision-making processes. Consideration must now be given to a carefully
constructed national multi-centre prospective randomised controlled study into the optimum management of this disease 相似文献

Transposition of the gallbladder to the left side without situs inversus viscerum is rare. These gallbladders are situated under the left lobe of the liver between Segment III and IV or on Segment III to the left of the falciform ligament. Because routine preoperative studies may not detect the anomaly, it may provide the surgeons with an unusual surprise during laparoscopy. Awareness of the unpredictable confluence of the cystic duct into the common bile duct and selective use of intraoperative cholangiography aid in the safe laparoscopic management of this unusual problem. 相似文献

We report a 40-year-old man with rheumatic heart disease who presented with abdominal pain for three weeks and hematemesis for 24 hours. CT scan showed a large splenic artery aneurysm without evidence of pancreatitis. Mycotic aneurysm due to infective endocarditis was considered and confirmed by echocardiogram, which showed aortic and mitral valve regurgitation and vegetations. He was managed successfully with coil embolization of the aneurysm and antibiotics. 相似文献
