Core Tip
Core tip: This case report demonstrates the importance of endoscopic biopsy using a cutting mucosal incision as a diagnostic tool for a submucosal mass that develops next to the staple line after sigmoid colon resection with a double-stapled anastomosis. We feel that these findings will be of special interest to the readers.
