I believe it can safely/effectively be done either way, and selectively use drains myself, especially if a patient is heavier (with more potential for fatty oozing), is having hip/flank liposuction concurrently (2/3 of the time), and especially if their risk factors for a blood clot (increased BMI, age, time on table, positive family history) require that we add Xarelto to their post-op regimen, which may cause some oozing. Usually a single lower abdominal drain is in place only 5-7 days, and doesn't cause a lot of headaches/discomfort, but it sounds like you're in better shape if you don't need adjuvant liposuction and therefore are a candidate for a drain-free approach (and we rarely see seromas that require further intervention in those cases . . . ) Hope this helped!
