Ok, that is what I thought...since mine was incorporated, I cannot give you a time frame, but I thought the rectum was less painful than the incision for my open procedure...I will tell you the rest of my story, but it is not to scare you, just inform you...if you don't want to know, stop reading!!!!
about 5 1/2 months post surgery, I had a rectal area abscess (I also had fistulas with my Crohn's so that could be the reason). It wasn't until I went in for surgery that it was discovered how deep it had become. It was cleaned out and I had a wound vac to help heal it faster...I was VERY impressed with how the wound vac helped speed things up...unfortunately, my insurance only covered a small amount so once I had to discontinue that, I packed the area for about 1 1/2 months to finish closing it...for me it was no big deal (mirrors are great), but for your husband if that is the case, you may have to pack it several times a day. I was still able to do my daily activities once the wound vac was removed (about two weeks)...I didn't really want to leave the house with a tube coming out of my pants (to a machine, too)...but having an open sore in that area wasn't debilitating.
You'll have to see what your doc says about recovery for your husband during your appointment. Your husband's diagnosis may make the difference for a better recovery!! And, like you have probably heard a million times, we are all different! I would love to hear how it goes and good luck to you both:)
