• Stenting
• Insertion of PEG tube
• ERCP

Safety

Most common complication is Sorethroat

Complication rate is 1 in 1000

• Bleeding
• Perforation

Risk of dilatation

• Review of 1862 endoscopic dilatations using Savary-Guillard technique showed complication rate of 0.18% for benign strictures and 4.58% for malignant aetiologies (Piotet E, Eur Arch Otorhinolaryngol.  2008 Mar)
• Certain strictures refractory to treatment and require multiple dilatations
• E.g. caustic, post-surgical, post radiotherapy strictures.
