Although congenital biliary abnormalities are common, preduodenal portal vein is very rare, not to mention preduodenal common bile duct (CBD) which has not been described before in the literature. A case with both anomalies complicated by biliary tract stones is reported. A brief review of embryonic development is also presented to explain the unusual biliary anatomy of this patient.
a b s t r a c tBackground: Laminotomy is one of the surgical treatments for spinal stenosis. Method: We conducted a prospective study including 58 patients with mean follow-up of 37.5 months, successful rate was 72%.Result: There were significant improvement of mean Japanese Orthopaedic Association lumbar score, Oswestry Disability Index(ODI), and visual analogue scale (VAS). Male had significantly better result in ODI and VAS. There was no significant difference regarding to older age (>65) or the presence of preexisting degenerative spondylolisthesis. One patient was found to have increased lumbar instability after operation. The overall reoperation rate was 6.9%.
Study design: Prospective study of surgical correction of thoracolumbar kyphotic deformity caused by ankylosing spondylitis. Objectives: To assess surgical outcomes and complications of thoracolumbar kyphotic deformity corrected with transpedicular closing-wedge osteotomy performed in a regional hospital. Summary of background data: There have been several studies reporting on the results of surgical correction of deformity in ankylosing spondylitis all over the world. However, there has not been any local data published. Methods: From 2003 to 2011, we had performed 12 transpedicular closing-wedge osteotomies in 9 patients with ankylosing spondylitis for correction of kyphotic and scoliotic deformity in thoracolumbar spine. Operative outcomes were assessed clinically by recording the Japanese Orthopaedic Association (JOA) scores, visual analogue scale (VAS) pain scores, Oswestry Disability Index (ODI) preoperatively and postoperatively and patient satisfaction postoperatively. Radiological outcome was assessed by measuring thoracic kyphosis, lumbar lordosis and sagittal plumb line preoperatively and postoperatively as well as the degree of surgical correction. Occurrence of complications was recorded by our standard audit protocol. Results: All patients had a single level of osteotomy done at a time. Most of the osteotomies were done at L2 or L3. The mean amount of correction was 21.6. Complications included dural tear, pseudoarthrosis and transient radiculopathy. The extent of correction and incidence of complications improved with experience. Conclusion: Despite transpedicular closing-wedge osteotomy being a major operation that is not without complications, most of our patients had good clinical results and subjective satisfaction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
