Laparoscopy? Not really, just Photoshop.
It’s incredible what you can get out of photoshop just by playing around with all it’s filters.
Here I simply started with a white background, add some noise, applied a gaussian blur and duplicated the layer multiple times, some more more noise. Again some blur, rotated some layer 90 degrees scaled them up and set different blending modes, I then flattened the layers, made more duplicates and added more filters from the artistic category. Last thing I add a new alpha channel with a radial gradient, this is for the depth of filed, then I applied a lens blur filter that uses this new alpha channel.
This is not a step by step tutorial since I missed many details that honestly I can’t remember, shame on me, nevertheless, it’s always a great fun.
