Good, except that “findings are not representative” seems to suggest that the pathologist could’ve found spleen in the morcellation tissue if they’d looked hard enough.
I do love “Clinical correlation is recommended”. 
So he accidentally went into the OR where they were scheduled to kill a different patient? A liver isn’t optional.
The way I understand it, most people with that condition never know about it, but that idea may have come from a time when diagnostic/surgical interventions that would reveal that knowledge were less common.
Maybe I’m being a bit to charitable, but I had imagined that the patient had some kind of disease process going on that made his organs “look weird” in a way that might explain the mistake. The dude was under the knife for a reason after all.
Given the situation, I’m wondering if the unfortunate pathologist ended up submitting the specimen in toto 
I can’t even imagine how many slides that would generate.
IOW, “don’t shoot the messenger”. 
That must be part of it. But they are SO different, in so many ways. I’m guessing the surgeon will lose his licence, at a minimum.
Illuminating, but I think your autocorrect stumbled over “ligated”.
That’s not how it works. The surgeon would have met with the patient and a team of other doctors before the surgery. They would have known the case very well. They wouldn’t be sent into a room to do a surgery and then look at a screen and been like, “hmm. OK, it’s a liver removal according to the paperwork. Let’s get started.”
Sucks for him but a real lucky break for that other guy.
That’s not how it SHOULD work. What of the surgeon didn’t know the case very well? What if the entire pre-op procedure collapsed? The entire hospital needs to be reviewed, stat.
When my husband had surgery to insert a metal rod in a broken leg, one of the medical staff (my memory of who was who and in what role is hazy after five years that were quite hectic in places) did that, mark the leg to be operated on with something Sharpie-like. Seemed reasonable to my husband and me.
Since a friend was performing her hysterectomy, I tried to get a relative to Sharpie THIS UTERUS on her abdomen.
A surgeon like this would probably say, “And where did you go to medical school?”
My doctor put an X over my left breast before doing my cancer surgery, just to guarantee that he’ll be operating on the correct area.
University of Wikipedia, with additional study at Google U. 
Still, I’d apparently do better than said “surgeon” did at distinguishing a spleen from a liver. Experience with seeing game butchered would likely cover that.
At one time, DOs were basically glorified chiropractors, and if a physician wishes to go into, for instance, academia, they’re going to want that MD, but for family practice, general surgery, etc. a DO is just fine.
My recently-retired family practitioner is a DO, and he was great. His replacement is an MD who was born the year after I graduated from college.
Back when I lived in the region, I went to Kirksville, MO (my original DO’s alma mater, BTW) which is the birthplace of osteopathic medicine, and visited their medical museum. It’s pretty small as museums go, but quite interesting. I noticed the large number of women in the old pictures, as in pre-WWI, and asked the docent if they had a nursing school at the time. He replied that Dr. Andrew Still, osteopathy’s founder, believed in the equality of women, and the school originally admitted men and women on an equal basis (not necessarily 50/50, but no 5 or 10% quotas like many other schools of the era did). Granted, this was when a DO was 2 or 3 years from start to finish, but it was still great to see.
Like “X marks the spot. Dig here”,
or
Like “X: do not enter”?
When I had my second cataract surgery done, all doped up with Valium and atropine drops, I was startled when the laser equipment started moving to my left eye, the one that had already been corrected. I yelped and started feebly protesting, at which time there was muttering behind me and the machine shifted over. At the end one of the techs asked another one, what does this mean, “Coordinates not found” and the reply was “Don’t worry, just shut it down.” 
This may be the real reason patients are rendered unconscious during surgery: to avoid embarrassing the team.
X Marks The Spot!
My 7th boobaversary (anniversary of diagnosis) is coming up on October 3rd.
I think the doctor may involve the patient in the marking process, so that everyone agrees on the area to be operated on.
