Booked for keyhole but the surgeon warned it might become open surgery. What decides which one I get, and does converting mean something went wrong?

I'm 59 and finally on the list to have my gallbladder out after two years of putting up with it. At the pre-op the surgeon was very straight with me, which I appreciated, but he said the plan is keyhole and there's a chance he has to "convert to open" once he's in there and gets a proper look. He explained it quickly and I nodded along and then spent the whole drive home worrying I'd agreed to something I didn't understand.

So what actually DECIDES it. Is it my age, is it something on the scan, is it just bad luck on the day. And the bit I really want to know, if he ends up opening me up with the big cut instead of the little ones, does that mean the operation went wrong or that he's a nervous type. It felt like he was warning me about a failure and I'd rather know now than wake up confused.

Mine was textbook keyhole, four little cuts, two of them barely more than nicks, one in the belly button. Home the same day. So that's the version everyone hopes for and it's genuinely the normal one for most people. But the surgeon warning you isn't him being nervous, it's him being honest, they all say it because they can't promise the inside will be tidy until they're looking at it.

Denise, I'm the one who runs this board and I had my own gallbladder out by keyhole, so I've stood exactly where you are with that same warning ringing in my ears, and I want to take the fear out of the word "convert" because it did nothing but frighten me too.

Keyhole (the proper name is laparoscopic) is the standard operation now, and it's what the surgeon plans for almost everyone: three or four small cuts, the abdomen gently inflated with gas, a camera and instruments through the little openings. Open surgery is one larger cut of roughly 10 to 15 cm under the right ribs, and it's held in reserve for when keyhole isn't safe or possible. Converting simply means the surgeon started keyhole, had a proper look, and decided the safest way to finish is through the bigger cut. My surgeon put it to me plainly: it happens in something like 5 to 10 out of every 100 operations, and it's far more likely when the gallbladder is badly inflamed, when there's scarring from previous surgery, or when the anatomy near the bile duct just isn't clear enough to be sure what he's cutting. That last reason is the important one, because the whole point of converting is to protect the bile duct, not because anything has gone wrong. Choosing to open up rather than push on blind is good surgery. The site's piece on keyhole versus open gallbladder surgery walks through when each is used, and there's a fuller one on the open operation itself if you want to see what that recovery looks like.

The honest trade is recovery. After keyhole most people are home the same day and back to themselves in a week or two; open surgery usually means a few days in hospital and more like four to six weeks to feel right. So the warning isn't about failure, it's your surgeon telling you he'll take the longer road if that's the safe one. Whether it's likely in your case, though, is a question for him with your scan in front of him, not for me.

My neighbour got converted to open because hers was really angry and inflamed by the time they operated, and she was in a few days and sore for a good month, but she healed up completely and never looks back on it as a disaster, just a slower road. Worth knowing the sooner ones tend to be more straightforward keyhole, so being on the list rather than waiting for it to flare is on your side, Denise.

Right, this is the explanation I needed and didn't get in the ten minutes at pre-op. Reading it as "he'll open me up to protect the bile duct if he has to" instead of "he might mess it up" has completely changed how I feel about walking in. Op is in three weeks. Fingers crossed for the four little cuts but I won't panic now if I wake up with the one big one.
