10.1 Introduction


Abdominoplasty is performed to shape the anterior and lateral abdominal walls. Different forms of contour deformity should be addressed with modifications and combinations of techniques. Either traditional abdominoplasty or high-lateral-tension abdominoplasty (HLTA) is usually combined with liposuction of the anterior abdominal wall and love handles giving satisfactory results most of the time. Although this combination covers a good percentage of patients complaining of lower abdominal sagging or bulging, some other techniques are also present such as mini abdominoplasty, fleur-de-lis abdominoplasty, and reverse abdominoplasty. Post bariatric patients need further ablative procedures such as dermolipectomy and belt lipectomy.

Besides being a rewarding surgery, abdominoplasty harbors a spectrum of cosmetic and non-cosmetic complications. By definition, abdominoplasty is considered to have the highest complication rate among aesthetic surgical procedures [1]. In order to decrease the complication rate and increase cosmetic results together with patient satisfaction, every single step of diagnosis and treatment should be controlled and tailored according to the needs and characteristics of each patient. Patient selection, operative design, surgical technique, and postoperative care should be detailed in order to minimize complications.


10.2 Preoperative Evaluation, Indications, and Contraindications


Most of the patients seeking abdominal contouring have some common features. These can be summarized as being unable to sustain a stable weight and conditioning and having history of pregnancy, massive weight changes, or abdominal surgery and some degree of abdominal wall laxity. Patients may or may not be obese. Besides these patients, a number of relatively fit patients also admit to have lower abdominal contouring in order to improve appearance.

In order to avoid major complications and patient dissatisfaction, patients should be elected according to some factors. One of the most important factors is to distinguish body habitus and either to disqualify patients having centripedal obesity or plan to operate on those patients in a staged manner, i.e., sequential high-lateral-tension abdominoplasty (HLTA) and reverse abdominoplasty or HLTA and liposuction. These patients have intra-abdominal visceral fat accumulation. This chronic process results in tissue expansion of the anterior abdominal wall with thinning of the fascial and muscular layers. Such a chronic biomechanical change cannot be reversed acutely in a 2-h operation addressing only the skin, superficial fascial system, and anterior rectus sheath. The body mass indices (BMI) of these patients are usually above 30, although rarely it can be between 25 and 30.

It is very important during consultation to physically show to the patient the intra-abdominal visceral fat accumulation if present so that they understand why the chosen surgical procedure will not leave them with a totally flat abdomen. The easiest way to do this is to put the patient in a sideways standing position in front of a mirror and grasp with a pinch maneuver the amount of superficial fat present (fat above the Scarpa fascia). The amount of abdomen protrusion seen after isolating this superficial fat in the pinch maneuver stands for the amount of abdomen muscle diastasis and intra-abdominal visceral fat present.

A history of rapid weight changes also indicates either uncontrolled diet and lifestyle or a metabolic predisposition due to dysregulated adipokine trafficking [2, 3]. Patients should be in the same weight range of +/− 10 pounds for a year. This range should be interpreted according to the ethnic and demographic factors of population. Like any other surgical procedure, patient should be cleared of uncontrolled comorbidities, such as hypertension, coronary artery disease, diabetes mellitus, vasculitides, and chronic use of medications or herbal adjuncts. Smoking has long been considered as a relative contraindication, and the patient should quit smoking at least 3–4 weeks before the operation. Excessive alcohol consumption might increase bleeding time especially with the use of nonsteroidal anti-inflammatory drugs.

A thorough physical examination should be performed. Abdominal scars which may compromise skin flap viability, e.g., subcostal or paramedian incisions, are noted. Diastasis recti and possible ventral hernias should be ruled out by physical examination in the upright and supine position, with and without Valsalva maneuver. In overweight or obese patients, hernias can be difficult to palpate. Although physical examination is usually enough to detect fascial dehiscence and most of the hernias, ultrasound examination should also be used for confirmation when needed.


10.3 Informing the Patient


Preoperative informing of the patient is crucial as always in aesthetic plastic surgery. The level of perception of a patient is totally different before and after the operation. Every aspect of the operation including length and height of the scars, amount of narrowing of waistline, functional layoff, change in umbilicus, and potential complications should be explained in detail. Surgical revisions might take place and should be told before abdominoplasty. Especially combined procedures, e.g., breast reduction plus abdominoplasty and thigh lift plus abdominoplasty, increase the incidence of complications and length of recovery.


10.4 Preoperative Preparation


The patient should adjust bowel habits to a more liquid diet to prevent constipation. Increased intra-abdominal pressure constitutes difficulty to close abdominal flap during surgery and also causes discomfort postoperatively. Some surgeons prefer to clean bowel with an enema the night before the operation. The patient should urinate before surgery to prevent a distended bladder resulting in increased intra-abdominal volume. This also might avoid the need for urinary catheter which can be a source of bacteremia in patients with obesity and/or diabetes [4]. The patient should discontinue smoking for at least 2–3 weeks before and 2–3 weeks after surgery. High-risk patients for deep vein thrombosis (DVT) should be given low-molecular-weight heparin 12 h prior to surgery and continued according to the Caprini scale scorings. Compression garments should be worn by the patient before surgery as well [5].


10.5 Postoperative Care


Postoperative period of abdominoplasty is usually straightforward with early mobilization, removal of drains in 2–3 days, and limited physical activity during the first 2 weeks. The patient is placed in bed with the head, knees, and feet elevated. Liquid diet is started and then advanced. Although subfascial infiltration of local anesthetics is useful, narcotic analgesics or a pain pump can be used for postoperative analgesia. Patient should be mobilized as early as possible. Compression garments or devices should be used until full ambulation is obtained. Patients should be walking slightly flexed at the waist for a few days. Although abdominal binders do not offer physical advantage for mobilization, they give a feeling of safety while walking. The abdominal binder is kept on for the first week, and it should not be so tight since increased intra-abdominal pressure increases the risk of thromboembolic complications.

Intermittent leg compression garments should be used until the patient is able to get out of bed. The use of compression socks for 10–20 days after surgery is also advisable.

Showering is allowed two days after the operation regardless if drains are in place. Since it takes some time to regain cutaneous sensation of the abdominal wall, patients are instructed not to apply heating pads to the abdomen or sunbathe. Driving is allowed whenever patient feels comfortable. Abdominal muscle exercises can be started after 4–6 weeks. Strenuous physical activities should be prohibited for 6 weeks. Patient should be informed that early ecchymoses and edema resolve in 2–3 weeks.


10.6 Main Complications of Abdominoplasty


Abdominoplasty is an extensive operation with potential risks and complications that need to be considered by both the patient and plastic surgeon. Abdominoplasty, which is usually combined with some extent of liposuction, carries arguably the highest complication rate among aesthetic surgery procedures. As a general rule, complications are more common in higher-BMI patients, and many patients that present for abdominoplasty are in the overweight-to-obese range [6]. Potential complications of abdominoplasty are discussed below.


10.6.1 Aesthetic Complications



10.6.1.1 Place and Quality of Abdominal Scar


Residual scar after abdominoplasty can be relatively long or highly leveled. Complaints on resultant scar can be exaggerated despite the scar being actually fairly well. Most of the time, this results from inadequate preoperative informing of the patient or selecting a patient with high expectations who does not accept mentioned possible surgical results. If the patient is cooperating with the surgeon during preoperative period and understands the needs of her body habitus, most of the time, a longer incision shaping the abdomen, flanks, and inguinal areas well enough is welcomed.

Asymmetric abdominal scar is another aesthetic complication almost always resulting from inadequate preoperative planning and intraoperative tailoring. Correction of dog ears should be performed with utmost precision. This can be accomplished with liberal use of liposuction laterally and excision of redundant skin step by step comparing both sides [7]. This is especially important in high-lateral-tension abdominoplasty where lateral excision is fundamental. This outcome is usually caused by a poor marking design with either an overestimation or underestimation skin redundancy below the incision. If there is significant excess below the incision, the resultant scar might be high riding. If there is no excessive redundant skin below the incision, the scar might be too low if too much skin is excised. As always in plastic surgery, the remaining volume is more important than the resected volume. Thus, remaining skin flaps must ensure a final scar shortly above the anterior superior iliac spinae. If the technique used is high-lateral-tension abdominoplasty, then some degree of thigh lift will be provided, and the final scar will be a longer one extending laterally above the anterior superior iliac spinae. Most of the patients, if the scar is thin enough and the operation gives good shaping of the flank and thigh areas, do not complain much about the length of the scar. Prevention of dog ears is a must during closure since, although the length of the scar is not a major patient complaint as described before; any skin excess especially in the lateral aspects of the scar can potentially end up with an unhappy patient.


10.6.1.2 Change in the Position of Pubic Area


One of the main reasons for a patient seeking abdominoplasty is ptotic mons. Abdominoplasty should also correct the position of the mons pubis at least to some degree. Placing the incision so close to the symphysis pubis, which is closer than 6 cm, results in a stretched and heightened pubis. Besides being a cosmetic deformity, this might lead to localized lymphedema of the area which may not resolve in long time. To place the incision too far from the symphysis pubis, which is further than 8 cm, avoids significant shaping of the pubis resulting in redundant pubic skin and soft tissues. Liposuction of the pubic area is a critical procedure which should be reserved for a very few number of patients. Besides being seemingly straightforward, overtreatment of this area with liposuction might result in permanent lymphedema and/or neurovascular damage of the clitoris. If any residual volume problems of the pubic area exist after abdominoplasty, this can be addressed with secondary partial excisions, limited liposuctions, and/or fat injections. In patients who have a highly positioned umbilicus, the mons pubis can migrate superiorly with closure of abdominal flap. This potential complication can be prevented by closing umbilical defect with a purse string suture or a T-shaped scar which may end up like a fleur-de-lis scar.

The quality of scar can be questioned by the patient. Patients should always remember that as plastic surgeons we cannot predict 100 % how a final scar will appear. This is very important to be addressed to the patient before the surgery since the final quality of the scar is multifactorial and includes endogenous patient conditions, surgeon´s operative techniques, and patient aftercare. Bad scars can be either hypertrophic or atrophic. Preoperatively, the patient should be questioned and examined about the quality of previous scars, if present. A history of hypertrophic scar or keloid is predictive of the quality of central transverse scar after abdominoplasty. Widened atrophic scars can be seen in patients with Caucasian origin. Atrophic scars are often the result of inadequate reapproximation of the superficial fascial system. The final status of a scar can be determined at 1 year postoperatively, and bad scars can be revised thereafter. Steroid injections often help to soften hypertrophic scars. Ablative laser procedures can also improve cosmetic result of a hypertrophic scar [8]. Keloids should be addressed with core excision combined with steroid injections.
