Current Issues Involving the Treatment of Small Rectal Carcinoid Tumors
نویسنده
چکیده
submucosal dissection, and local surgical excision, including transanal excision and transanal endoscopic microsurgery (TEM). In a study by Kim et al. [6], the complete resection rate for TEM was over 97%. Although TEM is superior to other endoscopic procedures, TEM must be considered to be more invasive because of the risk associated with the use of anesthesia. Third, guidelines for follow-up examination after initial treatment for a small rectal carcinoid tumor have not yet been established. Some authors recommend annual follow-up examination including a CT scan while others suggest that follow-up is not necessary [8-11]. Actually, Kim et al. [6] reported that only 38 patients of 109 patients with a rectal carcinoid tumor who had undergone TEM had more than three years of follow-up. Regretfully, the study of Kim et al. [6] is one of small case series on the treatment of rectal carcinoid tumors. Hopefully, largescale multicenter studies on the management of rectal carcinoid tumors will be reported sooner or later.

Small bowel obstruction by a terminal ileum carcinoid tumor: a case report
Abstract Carcinoid tumors are well differentiated neuroendocrine tumors with secretory components. These tumors are uncommon but the most common primary tumors of the distal small intestine. We present a rare terminal ileum carcinoid tumor presenting with a small bowel obstruction. A 65 years old man presented with intermittent, gen-eralized, dull and colicky abdominal pain accompanied with int...

Background: The bronchopulmonary carcinoid tumor accounts for 1-2% of all adult malignancies of the lung and 20-30% of all carcinoid tumors. Cushing’s syndrome is the result of chronic exposure to increased concentration of exogenous or endo-genus cortisol hormone, and it is generally associated with central obesity, metabolic syndrome, and hypertension. Treatment is based on decreasing cortiso...
متن کاملEfficacy and Safety of Endoscopic Resection Therapies for Rectal Carcinoid Tumors: A Meta-Analysis
PURPOSE Several endoscopic resection therapies have been applied for the treatment of rectal carcinoid tumors. However, there is currently no consensus regarding the optimal strategy. We performed a meta-analysis to compare the efficacy and safety of endoscopic mucosal resection (EMR) or modified EMR (m-EMR) versus endoscopic submucosal dissection (ESD) for the treatment of rectal carcinoid tum...

The aim of this study was to evaluate colonoscopy in the diagnosis and treatment of rectal carcinoid tumors with diameter <1 cm. Elevated lesions with normal mucosal appearance under colonoscopy were identified. Endoscopic ultrasound (EUS) was performed in 16 patients. Lesions diagnosed as rectal carcinoid tumors were resected by endoscopic mucosal resection (EMR). The diagnosis of specimens by...
متن کاملEndoscopic Resection for Rectal Carcinoid Tumors: Comparision of Polypectomy and Endoscopic Submucosal Resection with Band Ligation
BACKGROUND/AIMS Rectal carcinoid tumors, at diagnosis, are as small as 10 mm or less in about 80% of patients. These tumors are generally removed by endoscopic resection. The aim of this study was to compare treatment efficacy and safety between endoscopic submucosal resection with band ligation (ESMR-L) and conventional polypectomy. METHODS Between January 2005 and September 2010, a total of...
