Advanced endoscopic imaging in Barrett＇s oesophagus： A review on current practice

Over the last few years,improvements in endoscopic imaging technology have enabled identification of dysplasia and early cancer in Barrett's oesophagus.New techniques should exhibit high sensitivities and specificities and have good interobserver agreement.They should also be affordable and easily applicable to the community gastroenterologist.Ideally,these modalities must exhibit the capability of imaging wide areas in real time whilst enabling the endoscopist to specifically target abnormal areas.This rev...     

Neglected patellar tendon rupture: preserve the fat pad

Management of neglected patellar tendon ruptures remains a difficult therapeutic endeavor, as complications such as adhesions, proximal patellar migration, and quadriceps contracture occur. Treatment goals include restoration of extensor mechanism, both structurally and functionally, which allows active knee extension. Few cases of neglected patellar tendon rupture have been reported in the literature, however, all have used preoperative or additional intraoperative procedures to relocate the patella or to provide additional support to the reconstructed tendon. This article presents a case of a 25-year-old man whose diagnosis of patellar tendon rupture was delayed by 1 year. The patella was mobile and could be brought down to its original position manually. The patellar tendon was successfully reconstructed with autogenous semitendinosus and gracilis tendon graft. No preoperative or intraoperative traction was used on the patella. Quadriceps lengthening was not performed and no hardware was used between the patella and the tibia to augment the reconstruction. Scar tissue was not excised and was used to cover the hamstring tendons. The patient achieved a good functional result after 5 months of rehabilitation. At 14-month follow-up, the patient had returned to his pre-injury level of work with no deterioration of knee function.
