Usually physical examination will determine if a post-operative fluid collection exists. If it is not clear by examination, ultrasound or CT scan may be helpful. If a large hematoma is present, formal surgical drainage and insertion of a drain may be necessary. If only a serous fluid collection is present, the surgeon may be able to aspirate the fluid in the office under local anesthesia.
To understand what can be accomplished by a tummy tuck, one must consider the anatomy of the region. Four anatomical layers contribute to the abdominal appearance. The layers are listed below from the outside to the inside.
1. Skin
2. Fat beneath the skin (subcutaneous fat)
3. Abdominal muscles
4. Intra-abdominal contents (organs and fat within the abdominal cavity)
Tummy tuck can only improve layers 1 through 3. A tummy tuck removes excess skin. Fat from beneath the skin is also removed during a tummy tuck. Liposuction may be used as well to assist in removal of fat from beneath the skin. The abdominal muscles are tightened during a tummy tuck to flatten the abdominal contour. A tummy tuck cannot remove excess fat from within the abdominal cavity. The effect produced by abdominal muscle tightening is limited by how much fat is inside a patient's abdominal cavity. Therefore, not every patient can have an absolutely flat stomach after a tummy tuck. The presence of abdominal cavity fat can be estimated preoperatively by having the patient lie on their back. If the abdomen continues to protrude upwards while the patient is lying down, significant fat exists inside the abdominal cavity. This fat and the resulting abdominal protrusion will not be corrected by a tummy tuck. If a particular patient has significant fat within the abdominal cavity, I make that patient aware of this limitation of tummy tuck before the surgery.
As a result of pregnancy, the lower portion of a woman's abdominal wall may be more stretched out than the upper portion. While the objective is to evenly tighten the entire abdominal wall during a tummy tuck, sometimes the lower abdomen will be slightly tighter than the upper after surgery. This will cause a relative bulge in the upper abdomen by shifting the abdominal cavity fat upward. This usually resolves over time as the lower abdomen relaxes.
The preoperative photos presented appear to indicate the presence of significant fat within the abdominal cavity which would not be improved by a tummy tuck. The postoperative photos, show that excess skin and subcutaneous fat have been removed from the lower abdomen, resulting in a nice improvement in that area. The upper abdomen appears relatively unchanged postoperatively as I would expect due to the presence of fat within the abdominal cavity. The lack of change in the upper abdomen coupled with the significant improvement in the lower abdomen may make the upper abdomen appear to bulge more than it actually does.
