[Histonet] Histonet Digest, Vol 196, Issue 3 Incomplete sectioning

Two methods to avoid incomplete sectioning are:
1) ink the specimens well, using acetic acid (vinegar) to fix the ink, thereby making the ink easier to see in the block
2) have a microscope or 10 x lens adjacent to the microtome to allow for visual inspection. 
One of my histotechs used an old (really old- had a mirror for a light source) for years.  Gradually as scopes are upgraded, the 'retired microscopes can be put to use in the lab.

It is unfair to the histotechs that their work is judged by pathologists w microscopes, when the histotechs do not have access to the same tool, but life is not fair.

Each of our techs is responsible for fully facing their blocks and getting a representative section. If the docs see something is amiss (epidermis missing, incomplete cross section, etc), they can order a Technical Recut rather than a routine Recut. Unfortunately, it sounds like you (or someone else of authority), has to give some feedback/coaching that the sections are insufficient, particularly if it's a recurring problem. Is it one tech that needs a 1-on-1 convo, or a meeting with the whole staff to address widespread issues?

I suggest that each histotech is responsible for the blocks they cut and they cut the deepers on the their own blocks when they are requested. With feedback on the reason for the deeper from the pathologists they (the techs) will become more confident and learn how deep to cut.

A quality check can be accomplished in 2 places.  It can be done at cutting, but it should already be being done and it doesn't seem to be working.
Ideally, the stained H&E should be checked against the block face as it is pulled from the coverslipper to be given to the pathologist. Then it can be handed immediately to the tech that made the original error to  "do over"
Also, a common excuse will be "it was embedded poorly".  The answer to that is that it is the cutting tech's responsibility to hand back a poorly embedded block for it to be re-embedded if they feel that they can't get a representation section.
Remember, it could also be poorly cut gross, too.
Then you can nip it in the bud before the slide reaches the pathologist, and you can quickly identify who is turning out inferior sections and counsel them appropriately if needed.
Hope this helps. Terri

Good Morning HistoNetters,

I am reaching out to the histonet in hopes to get some suggestions from you on how to handle incomplete cross-sections of tissue in blocks. We are a small lab so this has not been an issue in the past but now that we are growing and our staff has increased I am getting feed-back from pathologist that the sections of tissue are not complete. They are asking for too many deepers that possibly could be avoided if it was cut deep enough to begin with. I have been given some managerial type duties ? which I don?t like cause I know nothing about managing people and I need to approach this but I need to approach this issue correctly.  Do you have the histotech compare his/her cut slides to the block to make sure that a complete cross-section is obtained and is this documented somehow?  Any and all suggestions I need.

Thanks in advance for your help and as always you all rock.. ?

Hello Histonetters,

Just wondering if anyone has had any benchmarks put in place in regards to blocks cut or slides produced per histotech/scientist per day? I realise that there are differing levels of complexity per block, we range from 1 slide per block to 21 one micron sections per renal block. Has any lab has WHS involved as far as Repetitive Strain Injuries are concerned?

I'm not looking for any definitive answers that I'll hold anyone to, just if anyone has expectations of maximum throughput. We have a tracking system that we can accurately see how much work each person is doing. There seem to be limits on how many cases a pathologist can report in  a day (again, varying levels of complexity) but what about for lab staff?

Any thoughts greatly appreciated.

Hi,

I'm searching online for a microtome where the sample is fixed and the
knife is moving. The microtome cutting movement needs to be motorized and
automatic.

Is there a microtome that has this functionality or is this something that
simply does not exist?

Thank you!
