Patient discussion about operator

Q. I am worried how safe the operation would be and the post surgery complications? My wife has a cyst in her right breast and further tests are going on. Doctors have advised to go for an operation. I am worried how safe the operation would be and the post surgery complications?

A. My friend, surgery for the cyst in breast is common. Any cyst in breast indicates breast cancer. These surgeries are very safe. Initially they used to cut the complete breast to remove the cyst. Now with the advanced technology, only the cyst would be removed without harming other tissues. Rather complete removal is done these days, but that depend upon the severity of the cancer. These surgeries are proven with results. If the cyst is less they will remove only the affected portion and yes they do remove some nearby tissues because there some cancer cells may lay and can arrive again. For any post surgery complications, chemotherapy treatment is also available.

Q. Should I do surgery for varicoceles? I went to an urologist and he recommended surgery, but I don’t know if I should do this…is it dangerous? Can I live with the varicocele?

A. I don’t see your problem, you said an urologist advised you to do so- that should be enough no? if you don’t trust him, go and get a second opinion. The surgery is not that bad, an hour later and you are walking out. Vary small risk of complication. I did it and it was fine.

Q. What types of gastric bypass surgeries are there? I heard all sorts of options for gastric bypass are available. What is the most in use?

A. Bariatric surgeries or – gastric bypass surgeries for weight loss fall into three categories: Restrictive procedures make the stomach smaller to limit the amount of food intake, malabsorptive techniques reduce the amount of intestine that comes in contact with food so that the body absorbs fewer calories, and combination operations employ both restriction and malabsorption. The exact one to be done should be decided with the physician according to each patients abilities and pre-operative function level.
