Hi Diver,
Well... I can't speak for any of their docs, as I have no experience with them, but here's what I'd do. Call their Gastroenterology department... the operator will send you over to them when you call if you ask. There, ask the person on the phone who the Head of the Gastro department is. Then get an appointment with that person as soon as possible (unless they aren't seeing new patients). When you see them, ask if the Gastro department operates as a team, meaning do they review their cases each week as a group to see if they're assigned to the right patients. Most large hospitals' Gastro departments do that to make sure they're using their resources the most efficient way possible. If they say no... then ask them how you get to the right doctor for your issues. Be blunt here, screwing this up will put you right back into a world of hurt. If the Head of the department isn't available, look at the list of Gastroenterologists in the link I posted above and find the one with the most experience in that specialty. If that's who you see, ask the same questions... how will you be sure you're seeing the best doctor they have for your problems. Also, when you get there for your appointment, an associate will bring you into the exam room and ask you a bunch of questions while entering all your data into the computer. Ask him/her the same questions. Is the doc you're about to see an expert in what your issues are? Ask them who else in the Gastro group is good at what you're being seen for (say in case you want a second opinion). Squeeze every last drop of info out of them, because you're interviewing them, not the other way around.
Back a million years ago, I had an abscess in my pelvic area that I thought was a bowel leak. The pain was a bit much, if you know what I mean. After waiting for a bed to be made available at Hopkins, that never seemed to materialize, I did a road trip up to the Cleveland Clinic. Those folks were wonderful. It turned out to be a psoas abscess and they simply stuck a drain in it and sent me back home. It was instant pain relief. All was good until I caught the end of the drain on the depth control lever on my tractor as I hopped off. The drain was instantly removed and I must have looked like an idiot trying to stick it back in. Long story short... an abscess in that area can be really painful... or worse if it pops and causes sepsis. So don't delay in getting some treatment. And let us know how it works out.
;O)
