Diverticulum

[Lion]

The man in the age of 66 years. Suffers from a diverticulum which is located in thoracal area of an esophagus, in current of 15 years. How there is an operation, and how much or as far as she is dangerous to a life?
Thanks!
P.S. still a glaucoma. Whether it is possible to pass or take place operation at this illness or disease?

And what bases for operation? Diverticulums of a thoracal department of an esophagus rather seldom require surgical treatment... Tell more in detail about complaints of the patient and results of the executed researches (it is desirable not later than evening mediums on July, 30th - I already in holiday).
