Fluoroscopy and endoscopy-guided transanastomotic rendezvous: a novel technique for recanalization of a completely obstructed colorectal anastomosis.

Background: Colorectal anastomotic stricture is a frequent complication that may affect up to 30% of patients. However, a complete obstruction is rare. Endoscopic balloon dilation is the first-line therapy, but it invariably requires being able to cross the stricture with the dilation device.

Accuracy of positron emission tomography and computed tomography (PET/CT) in detecting nodal metastasis according to histology of non-small cell lung cancer.

Positron emission tomography and computed tomography (PET-CT) is the non-invasive gold standard method for determining the oncological stage of patient with diagnosis of lung cancer. A correct preoperative staging is significant because only patients who do not have a history of regional or distant disease are those who will benefit from a surgical treatment. However, due to the different values of the PET-CT in terms of sensitivity and specificity to evaluate the mediastinal lymph node involvement, it is often necessary to perform a surgical mediastinal sampling through a cervical video mediastinoscopy (VM).
