I'm so pleased that it all went well. That operation appears to be a quick and easy one, where in fact it IS major surgery, just done without any major scars.
I too was a nurse and I cared for many patients after this operation. In the hospital that I worked in, the operation was considered dangerous enough that all post operative patients spent the first night in Intensive Care.
I hope all goes well for his recovery.
