Imho yes this is true. All surgical residencies are hard but I find that general surgery residents (and really the residency itself) is particularly soul-crushing. My two cents as to why:
1. The culture. General surgery, like general medicine, is old school and most old school attendings take particular joy in berating the new generation. It's what they went through, goddamnit, and it's what they know, so they're going to do it to the youth. You don't get this kind of backwards thinking in other specialties as frequently. The goal is to identify the weak and to break them and re-mold them, which doesn't fit with the paradigm of modern generations.
2. Residents have to do **** they don't want to do. A lot of people go into general surgery with an open mind, but some people know what they want to do (e.g., surg onc, breast, endo, etc.). Those who know what they want to do don't necessarily enjoy having to slog through the other services. Those who go to residency then figure out what they want to do in year 3 or 4 then take on this attitude sometimes as chief residents. Anyone who has to be on a service they don't like is going to perform less and give off a negative vibe.
2. The time it takes to train is too long. You can do brain surgery, spine surgery, and now heart surgery in just as much time (or sometimes less) as you need to become a specialist in say, the colon. Kind of ridiculous if you think about it. Especially since most of general surgery is now stapling, core knotting, and robotics, which in my opinion take less technical skill than say hand-sewn anastomosis.
3. The "general" training paradigm is not as well suited to modern medicine. The general training paradigm is a solid one, and it provides good breadth of exposure, but it is somewhat at odds with the focus of hospitals and payor programs today. People want specialists, not generalists, because we live in a consumer-driven world. Why take the guy who does a procedure twice a month when you can take the guy who does it everyday? That's what patients want and that's what companies/hospitals feel reduces risk.
4. The pay afterwards isn't that great. General surgery is about middle of the road when it comes to incomes an attending. Not great considering they work some of the worst hours in the hospital.
I'm not saying I agree with all of these but there is a glimmer of truth in many of them. That being said, I know plenty of people who love operating in the gut and for them all this stuff makes it worth it for them. No field is perfect.
I think many of these are quite exaggerated and certainly not the norm, but obviously, experiences are subjective. Here's my .02 regarding the "glimmer of truth" in the above comments:
1. The culture bit has some basis, perhaps more relevant when general surgery is compared to some "lifestyle subspecialties" (ENT/uro etc), but I don't think it applies to ortho/neurosurg/CT/vascular etc. As it was mentioned before, it really depends on the hospital/leadership/faculty.
2. Every specialty has aspects that are less attractive. I have not met a single (categorical) resident who hated the breadth of general surgery residency unless gen surg was their backup plan (typically those who didn't match ortho, plastics, neurosurg etc). But the same would apply to any "backup" plan. Most skills you get from general surgery are transferrable to whatever subspecialty one wants to do (if they wish to do one).
2#2. I agree that there may be opportunities to decrease the length of training for some subspecialties, however, I find this entire statement reductive and somewhat ignorant. While a straightforward colon case may be simpler technically than a CABG, there are a lot of intricacies in the care of patients with CRC and IBD, tons of trials coming out every year, new drugs, new surgical techniques (ie TAMIS, TaTME etc), and the landscape of management of CRC/IBD is constantly evolving (which is why I refer these patients to the specialists). Also, to say that most of general surgery is stapling and core knotting - I never expected to hear this from a surgeon in the 21st century. IMO, the technical part of the operation is about 20% of the overall surgical skills.
3. It is true that "generalists" are not well-equipped for the modern academic/urban healthcare systems where specialists thrive (for a good reason). However, once you get out of the academic/urban bubble, that system is not sustainable, and you need the "generalists" who can do a bit of everything - otherwise, the patients do not get any surgical care.
4. Can't disagree with that, unfortunately.
Overall, it's a matter of fit. If you are worried about lifestyle much, can't stand poop/pus, or want to have a yacht collection, gen surg is probably not a good fit. I went into gen surg because it would afford me the luxury to become an overall competent physician (who knows a bit about every part of the body, can manage the patient as a whole, and does not always depend on a bunch of other specialties) AND a subspecialist in the part of the body that I wanted to focus on.
