Hey Trex,
With regards to side-effects, read several posts on this site, but remember, people with problems will always shout louder than those without. I don't really have any problems, but if I eat a too high fat meal, then yes, I get a runny tummy, because the liver dumps Bile into the guts and the guts say no. Its not like there is no warning. I mean I start getting gut gurgles and cramps, and then I know I have to get to a loo sharpish, but you can do preventative measures if you are going to have a high fat meal. Such as make sure you have a high fibre diet anyway, and on the day take immodium, and other over the counter products, and as a lady, I line my knickers with a sanitary product, just in case (sorry if T.M.I. but I have a male friend who asks if he can have one or two and sticks them in his pants, if he is going out for a high fat meal with his mates, just so he feels safer). But I have to be honest and say I am soooooooo much better off without the GB than with it.
As far as the Naval type - I have a deep set naval and the infections were a pain, but it was manageable as long as I kept on top of it. I had my surgery in June 2010, and my naval is completely normal now. I get the occasional infection but that's only if I haven't taken care to cleanse the site when showering, and dry it after, where as before I'd wash it well, but not actually take time to dry it inside. It actually didn't hurt like I thought it would. If anything, deep inside, it felt shallower, but visibly and now a few years on, it feels no different than before.
The surgery I had was in the Redhill Hospital in Surrey, and was Scar-less, Clip-less, Laproscopic surgery, using Micro instruments. I have no other entry points other than via the naval which is invisible as the incision was very deep, so no scars or incisions on the surface, and also, I have no clips left inside me. I would recommend this treatment for anyone worried about appearances or number of entry points, provided your surgeon agreed. I was a guinea pig for the technique, but I believe it is wider available if requested, and you are able to choose where you have surgery and by whom, via the Book and Choose service the NHS offer.
I should say that if you don't go the navel route - then you may well be left with a painful several inch long deep incision in your side. The navel heals quickly and has limited nerves, so pain is more like a deep bruise than an all out "OH GOD I NEED MORPHINE AND DRUGS!!!!!!" - and this is something coming from someone (me) who believes I am allergic to pain! LOL.
I hope you don't have your GB out, but if you do, it is unlikely to be as bad as you think it will be - and this also comes from someone who was so terrified of the prospects of side-effects, I virtually drove myself into a mental breakdown from fear!....... and now I know I was wrong to be so afraid, as for me, I took my time in recovery by realllllyyyy slowly re-introducing foods, so that I hoped it would almost re-teach my body how to respond to fats, without using the gallbladder to do it. The people I know who did have issues, were those who as soon as they were out of hospital, dived into a diet of junk and high fats almost immediately - then wondered why they were ill. I didn't have a full fatty meal until 18weeks after the operation, and even then, I ate a lot of fibre in the day to help my body when the fats arrived. I was soooooo looking forward to that Fish and Chip meal - and when I had it, I found I didn't like it, because it tasted too fatty and greasy anyway! Hahahhahahahaaa!
Good luck out there Trex. :o)
