INTRODUCTION Carcinoid tumors (CTs) represent the most common type of neuroendocrine tumors (NETs). Digestive CTs in the gastroduodenal and colorectal tracts may be assessed using endoscopy and echoendoscopy or endoscopic ultrasonography (EUS) with the goal of attempting local resection with curative intent without having recourse to surgery. OBJECTIVE Endpoints in this study included:--Asses...

The evolution of the colorectal cancer (CRC) from a precursor lesion, the adenoma, was reported for the first time decades ago. Today the relationship between a polyp and CRC is widely known, the adenomatous polyp being considered a sequence in the development of this type of malignancy. Early diagnosis, monitoring and, above all, polyp resection represents one of the most efficacious methods i...

Removal of precancerous lesions during colonoscopy reduces colorectal cancer (CRC) incidence and mortality [1]. Recent data have highlighted that interval CRC occurs despite previous colonoscopy. Incomplete removal of polyps is one of the factors leading to interval CRCs [2]. Incomplete polypectomy of sessile serrated polyps (SSPs) is four-fold higher than that of conventional adenomas [3] and ...

One hundred and fifty cases of ulcerative colitis were assessed by total colonoscopy with multiple biopsies. Inflammatory polyposis was found in 25 (17%) cases and six of these had a large (greater than 1-5 cm) solitary polyp which radiologically resembled carcinoma in four cases. Adenomatous polyps were discovered in four cases. Three carcinomas were found at endoscopy, of which two were entir...

A 67-year-old man presented with food impaction and was found to have a gastric polyp obstructing the esophageal outlet. Due to the polyp's location and size, no immediate endoscopic intervention was performed, and the patient returned for intraoperative endoscopy and polypectomy. Cases of gastric polyps causing esophageal obstruction have not been identified in the literature. This case is uni...

rare benign esophageal tumor, and is usually asymptomatic [1]. More and more patients with esophageal heman− gioma are being treated endoscopically [2 ±3] by combined techniques in order to prevent massive bleeding, although the advantages are still controversial. A 68−year−old Chinese male, complaining of intermittent pharyngeal obstruction, was found to have a round, smooth pro− truding lesio...

BACKGROUND It has been established that the removal of adenomatous colon polyps drastically reduces the incidence of colorectal cancer (CRC), but polypectomy is not without risk. The aim was to determine the correlation between the results of an optical biopsy system and the histopathology report of the physical biopsy specimens of the same polyps removed at colonoscopy. PATIENTS AND METHODS ...
