A foreign body lodged in the rectum is not a common surgical emergency, and it is somewhat rare for a foreign body to penetrate the rectal wall [1], but if this does occur and the object is not removed in a timely manner, there can be a variety of serious consequences [2]. The removal of foreign bodies from the rectal wall poses a challenge to the surgeon. In this article, we introduce a new type of navigation device which can accurately identify the position of a foreign body in the rectal wall. By using this device, it was possible to remove the foreign body using a minimally invasive technique.


The new navigation technique we applied is called “surgical approach visualization and navigation” (SAVN) system (Santan Medical Technology Limited, Hangzhou, China) and uses a visible laser beam to simulate X-rays emitted from a C-arm X-ray machine [ 3]. It consists of a data processing module connected to the monitor of the C-arm, and the laser driver device is...
