Advanced esophageal neuroendocrine carcinoma.

Case report of an advanced esophageal neuroendocrine carcinoma with hepatic metastasis.

Are intracystic chromogranin A and neuron-specific enolase useful in the diagnosis of cystic pancreatic neuroendocrine tumors?

Value of choromogranin A and neuron-specific enolase intracystic (EUS-FNB) in the preoperatory diagnosis of cystic pancreatic neuroendocrine tumors.

Is canalization to obtain a deep biopsy of gastrointestinal subepithelial tumors miniprobe-guided an alternative to conventional known techniques?

Multicenter, retrospective database review and topical of 46 patients consecutives with subepithelial gastrointestinal tumors (SET). The diagnostic accuracy of deep biopsy miniprobe-guidded: 87%. Complications: seven minor bleeding (15%).

Endoscopic management of gastric neuroendocrine tumors: an analysis of 50 cases.

Of 50 cases gastric neuroendocrine tumors, in 30 (60%) endoscopic treatment, with relapse rate of 25%, perforation 3,6% and bleeding 7,1%.

Miniprobe Endoscopic Sonography for Gastrointestinal Tract Assessment: A Case Series of 1451 Procedures.

Conventional endoscopic sonography has allowed precise diagnostics without disturbances, and miniprobes can be easily introduced through the biopsy channel of the endoscope. Miniprobe endoscopic sonography has many benefits compared with conventional endoscopic sonography. Although there are well-known indications for miniprobe endoscopic sonography in endoscopic digestive tract assessment, there is still a need for this method to be widely spread among physicians and commonly used by most endoscopists.

Canalization technique to obtain deep tissue biopsy of gastrointestinal subepithelial tumors as an alternative to conventional known techniques.

Background And Objectives: The most accurate technology to detect and diagnose subepithelial tumors (SETs) is the endoscopic ultrasonography (EUS) combined with puncture techniques, such as the endoscopic ultrasonography-guided fine-needle aspiration (EUS-FNA) or the endoscopic ultrasonography-guided fine-needle biopsy. Going further in the improvement of the results of tumor samples obtained endoscopically to diagnose the SETs, the canalization technique guided by miniprobes (MPs) to obtain biopsies of SET could be an alternative to EUS-FNA. The objective of this study is to analyze the results of samples obtained by this procedure.

A rectal neuroendocrine neoplasm.

The incidence of gastric and rectal carcinoids is increasing. This is probably due to endoscopic screening. The prognosis is primarily dependent upon tumor size, aggressiveness (pathology, Ki-67), metastatic disease and stage.
