I've seen two pts with major GI bleeds go to surgery in my short experience with surgery, the first on my first week...pt was admitted to the ICU by medicine for profuse GI bleed, they couldn't catch up (I don't recall if GI got involved). At any rate, pt underwent ex-lap and was found to have an ulcer that perforated and eroded the gastroduoedenal artery...can't fix that with an endoscope!!
Second pt was just last month, acutally I was in the MICU. Pt was admitted with GI bleed, scoped from above and below, no source ID. Then had tagged red cell study which showed LUQ bleed, later locaized to proximal jejunum on arteriography. IR couldn't embolize due to constriction of vessels, so he went to OR. It must have been a very cool case (I talked to the resident later). They did multiple enterotomies (small holes in the bowel) and GI came, scrubbed and with a sterile scope scoped the entire small bowel. No bleeding found, pt did well, HCT stabilized, and on POD 4 we wrote transfer orders to the floor (pt stayed on medcine service the entire time, followed closely and primarly managed by surgery..acutally transplant as he is a kidney recipient). As he was about to go to floor, he got on the bedside commode, dropped his pressure and became apneic, after passing about half the bucket worth of blood!!! So I paged the surgery resident, and off we go again to the IR suite, now bleeding again in the same place, but this time they were able to embolize. Surgery still had to follow, as a possible complication of the emboization is ischemia of that segment of bowel. OK, so surgery didnt' actually fix this pt, but they were very much involved in the care of the pt who was acutally much more complicated than I described and it was surgery who provided all his ICU care, despite the fact that the MICU team was primary (MICU team also made some errors in his managment,and basically wound up just staying out of surgery's way). He required lots of knowlege and finesse to manage, and I learned more from this patient than from almost any pt I have had so far, on any rotation, though most of my education came from staying after my MICU hours were over and discussusing his case at length with the surgery resident.
Anyway, hopefully you can tell from my posts that I absolutely love the field of surgery. I promise it offers plenty of intellectual challange, and I'm getting really sick of the dumb surgeon myth and plan to do all I can to dispell that myth. I hope Brewster likes surgery as much as I do. If not , I hope s/he can find a field that s/he likes as much as I like surgery. Life is so much better when you love your job!!
