Objective: To analyse the short and long term outcome of endoscopic stent treatment after bile duct injury (BDI), and to determine the effect of multiple stent treatment. Design, setting and patients: A retrospective cohort study was performed in a tertiary referral centre to analyse the outcome of endoscopic stenting in 67 patients with cystic duct leakage, 26 patients with common bile duct leakage and 110 patients with a bile duct stricture. Main outcome measures: Long term outcome and independent predictors for successful stent treatment. Results: Overall success in patients with cystic duct leakage was 97%. In patients with common bile duct leakage, stent related complications occurred in 3.8% (n = 1). The overall success rate was 89% (n = 23). In patients with a bile duct stricture, stent related complications occurred in 33% (n = 36) and the overall success rate was 74% (n = 81). After a mean follow up of 4.5 years, liver function tests did not identify ''occult'' bile duct strictures. Independent predictors for outcome were the number of stents inserted during the first procedure (OR 3.2 per stent; 95% CI 1.3 to 8.4), injuries classified as Bismuth III (OR 0.12; 95% CI 0.02 to 0.91) and IV (OR 0.04; CI 0.003 to 0.52) and endoscopic stenting before referral (OR 0.24; CI 0.06 to 0.88). Introduction of sequential insertion of multiple stents did not improve outcome (before 77% vs after 66%, p = 0.25), but more patients reported stent related pain (before 11% vs after 28%, p = 0.02). Conclusions: In patients with a postoperative bile duct leakage and/or strictures, endoscopic stent treatment should be regarded as the choice of primary treatment because of safety and favourable long term outcome. Apart from the early insertion of more than one stent, the benefit from sequential insertion of multiple stents did not become readily apparent from this series.
A check X-ray following internal fixation of hip fractures after adequate peroperative image intensifier guidance is not useful. Dismissing this unuseful medical investigation, leads to less radiation exposure, less pain and less costs.
A 59-year-old woman with a painful right knee that became locked in extension after a trivial trauma was seen at the emergency room. This was caused by unloaded hyperextension in bed. She was diagnosed with a superior dislocation of the patella. A closed reduction was performed, but a recurrent episode was seen within a week. An arthroscopy was performed, in which the causative osteophytes were removed. In the 12-month follow-up after treatment, no recurrence was seen. A superior dislocation of the patella is caused by patellofemoral osteophytes that interlock. This can cause a degenerative knee to become locked in extension. Beside interlocking osteophytes of the patella and the distal femur, the superior part of the patella is tilted away from the femur. This is caused by the pull of the patella tendon and the simultaneous relaxation of the quadriceps tendon. This is a pathognomonic finding on radiographs that, to the best of our knowledge, has been identified but not been appreciated as such in previous reports. As illustrated in this report, a superior dislocation of the patella can easily be recognized on physical examination and radiographic imaging alone when familiar with the specific abnormalities. This will reduce unnecessary diagnostic imaging studies and delay in treatment. This case report illustrates a recurrent case of superior dislocation of the patella. We summarize and evaluate previous reports, discuss trauma mechanisms, physical examination, classification, and treatment including recurrent cases. After reading this case report the reader will be able to diagnose a superior dislocation of the patella with near certainty on physical examination and radiographic imaging of the knee alone.
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.
