Complications Associated with Endoscopic Treatment

Double-balloon endoscopy enables reliable manipulation of the endoscope even in the distal small intestine, and it allows endoscopic treatments such as endoscopic hemostasis and dilatation of a stenosis. It is, however, important to understand the thinness and fragility of the intestinal wall, and perforation and other complications due to forcible manipulation should be avoided.

When coagulation procedures are performed with high-frequency current, thick tissues such as tumors may coagulate without injection. In general, however, it is safe to coagulate tissues in combination with submucosal injection.

Dilatation should be avoided for stenosis if there is an acute inflammation or ulcers, and the expansion diameter should be kept to a minimum. It is not necessary to dilate the stenosis all at once: Endoscopic dilatation can be repeated as needed.
