Removal of a large foreign body in the rectosigmoid colon by colonoscopy using gastrolith forceps

Figure 1 A 40-year-old male was admitted due to retention of a large foreign body in his rectal colon. Plain abdominal radiograph revealed a bottle shape foreign body (measuring 38 mm × 75 mm) retained in the rectal colon, with no sign of perforation.

Figure 2 Bottle slid into the rectosigmoid colon deeper during examination. We decided to have a colonoscopy as a last method before cutting him open. In the colonoscopy, the glass bottle filled the colon 15 cm from the anus.

Figure 3 The use of snare and basket failed to ensnare the foreign body. We used gastrolith forceps to retrieve the bottle. The bottle was carefully and slowly manipulated to the opening of the anus and successfully removed out by colonoscopy.
