Knife-assisted resection (KAR) for small rectal neuroendocrine neoplasia

Is endoscopic ultrasonography essential for endoscopic resection of small rectal neuroendocrine tumors?

AIM To evaluate the importance of endoscopic ultrasonography (EUS) for small (≤ 10 mm) rectal neuroendocrine tumor (NET) treatment. METHODS Patients in whom rectal NETs were diagnosed by endoscopic resection (ER) at the Pusan National University Yangsan Hospital between 2008 and 2014 were included in this study. A total of 120 small rectal NETs in 118 patients were included in this study. His...

Proper Treatment Option for Small Rectal Neuroendocrine Tumors Using Precut Endoscopic Mucosal Resection

Endoscopic Resection for Small Rectal Neuroendocrine Tumors: Comparison of Endoscopic Submucosal Resection with Band Ligation and Endoscopic Submucosal Dissection

Background and Aims. There is no consensus so far regarding the optimal endoscopic method for treatment of small rectal neuroendocrine tumor (NET). The aim of this study was to compare treatment efficacy, safety, and procedure time between endoscopic submucosal resection with band ligation (ESMR-L) and endoscopic submucosal dissection (ESD). Methods. We conducted a prospective study of patients...

Are Small Rectal Neuroendocrine Tumors Safe?

Although CT scans do not reflect lymph node metastasis as accurately as a pathologic examination, a case may be regarded as negative for lymph node metastasis if no signs of metastasis appear using CT. 6 Therefore, the authors of the current case 7 reexamined a 7-mm perirectal lymph node identified on a CT scan after EMR for a 8-mm rectal NET. The pathological type of tumor also significantly a...

Simultaneous Laparoscopy-Assisted Resection for Rectal and Gastric Cancer

Laparoscopy-assisted surgery for either rectal or gastric cancer has been increasingly performed. However, simultaneous laparoscopy-assisted resection for synchronous rectal and gastric cancer is rarely reported in the literature. In our study, 3 cases of patients who received simultaneous laparoscopy-assisted resection for synchronous rectal and gastric cancer were recorded. The results showed...
