Table of Contents

Extraction of foreign bodies from the rectum is a major challenge in therapeutic endoscopy [1] [2]. The use of a standard polypectomy snare is hampered in cases where the foreign body is slippery or too large to place the polypectomy snare around the foreign body.

A 33-year-old man presented to our emergency department several hours after inserting a vibrator into his rectum. At clinical examination there were no signs of perforation. At flexible sigmoidoscopy the vibrator was visualized in the distal sigmoid. Multiple attempts to grasp the distal part of vibrator with a standard 30-mm polypectomy snare (Captivator, Boston Scientific, Natick, Massachusetts, USA) failed and the snare was deemed too small ([Fig. 1]).

Grasping the proximal end of the vibrator failed for similar reasons. Moreover, attempts to facilitate the positioning of the snare around the vibrator with a forceps using a second endoscope were unsuccessful. Therefore, we decided to construct a giant snare using a folded 450-cm guide wire (Jagwire, Boston Scientific, Natick, Massachusetts, USA) and a pusher from a 7-Fr endoscopic retrograde cholangiopancreatography (ERCP) biliary stent system (Flexima Biliary Stent System, Boston Scientific, Natick, Massachusetts, USA) ([Fig. 2]).

Using a gastroduodenoscope, the giant snare was easily placed around the distal end of the vibrator. With gentle traction the vibrator was removed ([Fig. 3]).

Thus, when a standard polypectomy snare is too small to grasp a foreign body in the rectum, a giant snare can be made simply using a folded guide wire and an ERCP biliary stent pusher.
