Diagnostic laparoscopy is safe and effective in the diagnosis of liver diseases. In liver transplant patients, laparoscopy has a valuable role in the early detection and staging of hepatic lesions. Laparoscopy is helpful in the early detection and staging of primary hepatic malignancy. With the increase of liver transplantation around the world, gastroenterology and hepatology programs should re-evaluate the role of laparoscopy in the diagnosis of liver diseases.
AIMS: To describe a new technique of intra-operative ultrasound-guided needle localization of impalpable intratesticular lesions. MATERIALS AND METHODS: Three patients with impalpable testicular lesions identified on ultrasound underwent needle localization under ultrasound guidance. The procedure was performed in the operating theatre under general anaesthetic using a 7.5-8 MHz linear array probe and a portable ultrasound machine. Under direct guidance, a 21 G needle was placed through the centre of the lesion allowing resection and immediate frozen section analysis. RESULTS: In two patients malignancy was confirmed and an orchidectomy was performed. In one patient a benign lesion was detected obviating the need for orchidectomy. CONCLUSION: Patients presenting with impalpable testicular lesions can pose a diagnostic dilemma and orchidectomy is often performed. We describe an ultrasound-guided intra-operative localization technique enabling direct pathological examination so surgical approach can be re-evaluated in the presence of a benign lesion. This is particularly important in the case of a solitary testicle in order to preserve testicular function.
