UPPER GI ENDOSCOPY
(Therapeutic)
Esophageal dilation.
The possible complications depend on the type
of used technique and the cause of the stricture.
achalasia (usually
pneumatic dilation ) |
peptic strictures
: |
- bougies systems
- TTS balloons |
malignant strictures |
The reported procedure-related to morbidity
rate:
6.4 % in peptic strictures
6.6 % in achalasia
The risk of major complications is greater when complex strictures (long/angulated)
are treated.
Possible complications of Esophageal dilation
Bacteremia
Bacteremia is one
of the most commons complications after endoscopic esophageal dilations. It
occurs after 45 % of procedures.
Perforation
The complication rate ranges
- 0-8 % dilation of peptic strictures
- 6.6 % achalasia dilation
Copy injury of parietal wall of the esophagus
by balloon dilation

(left upper part
of endoscopic view).
|

Esophageal perforation by fractured guide wire. |

Esophageal perforation occluded by plastic
stent |
Bleeding
A small amount of oozing from granulation lining of the stricture is
inevitable and requires no more action than rinsing and watching.
Serious bleeding is usually associated with a more serious injury (extension
of the tear to the submucosa).

Post balloon dilation bleeding.

Persistant pain
Fever
Delayed tracheo-esophageal fistulas
