A 19-year-old man presented at the emergency department, 12 h after insertion of a high pressure container with tanning spray into his rectum. |
|
|
2 |
A plain abdominal radiograph (Figure 1) showed the container in the rectosigmoid region. |
|
|
3 |
There were no signs of perforation. |
|
|
4 |
A flexible sigmoidoscopy was performed under conscious sedation. |
|
|
5 |
The object was located just above the rectosigmoid junction. |
|
|
6 |
The container could not be extracted by bimanual manipulation. |
|
|
7 |
An attempt to remove the object with conventional endoscopic instruments, such as polypectomy snares, was unsuccessful. |
|
|
8 |
The sigmoidoscope could be passed alongside the foreign body to its proximal end. |
|
|
9 |
A guide wire was left behind with the sigmoidoscope removed. |
|
|
10 |
Subsequently, a 40 mm pneumatic dilatation balloon (Rigiflex®, Boston Scientific), normally used in achalasia patients, was inserted over the guide wire and inflated just above the container (Figure 2). |
|
|
11 |
For safety purposes, the sigmoidoscope was reintroduced alongside the catheter of the balloon to allow endoscopic visual control of the distal end of the container in the rectum. |
|
|
12 |
Gentle traction was exerted on the balloon catheter, and the container was successfully removed under fluoroscopic and endoscopic control (Figure 3). |
