This comes up about once every few months so let me save everybody the hassle.
A) It's a competitive field to get into, not where they send the "bottom of the barrel" physicians.
B) The field is popular becuase it's a surgery field where you can still have a lifestyle. There are very few "Colorectal" emergencies (just like there are few urological or breast emergencies) so most cases are scheduled in advance. So, when you have your cases end at a certain time on Thursday so you can get to your kid's T-Ball game, you're not going to be called back because somebody with a surgical abdomen just wandered into the ED.
C) This is true for a lot of surgical fields, but they have very satisfied patients because they tend to have good results. This can be anything from treating a painful rectal fissure or external hemmorhoid to saving someone's life by resecting a mass.
D) Like many surgical specialties or fellows, their practice is a mix of surgery and seeing patients in clinic. So patient A may be perscribed medical management type solutions for early management of their Ulcerative Colitis/Proctitis but the next patient you may have a problem which can be easily fixed with a surgical procedure.
E) The people in the field (in my experience) tend to be cool guys and gals who you'd want to work with and are enthused about their work.
