Coffee enemas (in my estimation) do NOT take the place of liver flushing...but they're the absolute PERFECT "prep" and after-flush cleanse. The only successful healer that I know of that used coffee enemas in place of liver flushing, had patients doing up to four coffee enemas daily (that was Dr. Gerson)...and that's really not a "do-able" scenario for most folks. Also, Gerson's protocol/diet has/had extremely limited amounts of fat & oil...so perhaps that's one of the reasons he chose coffee enemas instead of flushing.
The only time I would say a coffee enema should take the place of liver flushing is when someone is totally unable (or unwilling) to flush. They will open up and cleanse the liver...and for some folks in extreme crisis (that absolutely canNOT ingest oil due to strong reactions), this is the perfect tool to get the liver open and flowing so they can get to the point that they CAN flush.
Here's where you get the best organic coffee for enemas:

Basic Coffee Enema Procedure and Recipe
(I believe there's a misprint in these instructions though, you should be on your LEFT side when accepting the fluid, and stay on your left side or back through the entire enema process. That's to keep the solution contained -as much as possible- in the sigmoid colon, where the main vein to the liver is located. And to prevent the solution from going throughout your entire colon (which can result in a lot of caffeine being absorbed because some of the solution ends up staying in the colon). You just want to put in a couple of cups worth of solution, retain it for 10-20 minutes, expel and repeat.
Also, here's the world's GREATEST selection of coffee enema research, stories, testimonies and facts...reading through even a few of the selections will give you TONS of information.

Also, there's an Enema forum on Curezone that'll offer you lots of information and support if you have other questions.
Also, there are tens of thousands of people that do a coffee enema daily...not only does it assist the liver to create bile, cleanse itself (hence helping the liver handle daily toxins), but during the time the enema solution is retained, the liver is turned into a "free radical dialysis machine", and everytime the blood passes through the liver (once every three minutes), the bloostream is cleansed of free radicals. It's also a highly effective method for relieving all kinds of pain.
Personally, I wish I had time to do one every day! But I always do one a day for three days before a liver flush (it seriously loosens things up in there to get it all ready to come out with the flush), and I do one whenever I feel any type of liver-ache or discomfort. I also do them daily when cleansing for parasites...I've gotten out HANDFULS of flukes just from eating 3 raw garlic cloves a day and doing coffee enemas daily for 3-4 days. (I did that for 4 days every day, and the next flush a week later showed absolutely ZERO flukes...but there were a couple of things that looked like eggs).
'Hope that gives you all the information you need :)
