Darth Maul headcanon & Anatomy research:
TW: mild gore in reference to internal organs.
*I'm not a medical expert, just a sci-fi nerd*
For my own references, I wanted to research how much Maul lost internally during his bisection.
Based on the remaining shape of his ribcage, I would hypothesize he was cut around the smallest part of the waist.

Source B. 3D rendition of a skeleton with internal organs.
If I'm right, here's a list of organs he would lose:
Small intestines [Duodenum, Jejunum,Ileum],
Large intestines [Cecum, Colon],
Possibly damaged: kidneys, stomach, pancreas, and Gallblader. All this depends on their size, placement, and the width of a lightsaber blade.

Comment below if you want me to explore the purposes of each organ he loses.
Here's where my weird head canon comes in:
What if Maul used the native Anacondan species as an organ transplant since snakes are pretty much one long intestine. We know that organic matter can be moulded to cybernetics through Mechu-deru, as shown in Star Wars Legends with the technobeasts.
Yes, the dark side sustains him, but we also see him hunting and scavenging for food on Lotho Minor, which means his body still craves sustenance, and he's still eating.
