AESTHETIC MEDICINE AND SURGERY
SKIN CANCER AND DERMATOLOGIC SURGERY
All surgical procedures, even for patients in good health, carry some risk and can result in unpredictable complications. Post-bariatric patients are at increased risk for post-operative complications.
It is of the utmost importance to implement all preventive measures to mitigate the risks where possible, by reducing and eliminating common risk factors such as smoking, obesity and concomitant disease, which are open to treatment before the operation. Likewise, it is crucial that patients follow meticulously all indications given by the surgeon post-operatively; correct wound management (sterility), intake of prescribed medications, appropriate pressure garments etc.
Despite the above-mentioned preventive measures some complications may still occur, fortunately to a minor extent in the majority of cases. Systemic complications, e. g. anaesthesia-related, are very rare. The complications related to post-bariatric abdominoplasty are mainly:
- bleeding: minor bleeding is normal after surgery and applying pressure with a swab is sufficient to control it;
- haematoma: a localised collection of blood, quite rare, which can occur within the first 24 hours after surgery. In the most severe cases it is necessary to reopen a portion of the wound to drain the blood and correct the root cause;
- infection: thanks to the post-operative antibiotic administration, the risk of infection is very low. If an infection does develop, further specific antibiotics and local disinfection are required;
- wound dehiscence: breaking open of the surgical incision along the suture. This is a rare complication which, if minor, heals spontaneously with dressings. If wound dehiscence is extended, it is treated with a new suture;
- skin slough: in extremely rare cases skin damage may occur in the affected areas, because of reduced blood supply. The healing process causes scarring, which is usually inconspicuous and can be improved with a minor operation (scar revision), if necessary. For the same reason partial or total loss of the navel can occur. In this case navel reconstruction is possible at a later time;
- recurrence of abdominal tissue descent: this is rare, but the risk is higher in ex-obese patients, due to the loss of elasticity and tone in the tissues following massive weight loss;
- pathologic scars (hypertrophic/keloids): scarring, despite preventive measures (paper taping, silicone gel, sun protection) can develop pathologically, both as a consequence of a personal predisposition and of complications (e.g. infection, wound break-down): widened, uneven, pigmented scars. In such cases, once the scar has settled for at least 6-12 months, scar revision may be necessary.
It is noteworthy that for people in good health, whose pre-operative blood tests are within the normal range, statistics show that the incidence of serious complications is very low. If complications do occur, it is crucial for patients to be emotionally stable in order to face and overcome them. In this respect, support from partners and/or relatives can play a major role in the recovery process, thus it is advisable to avoid having surgery without a support network. Additionally, an open and honest dialogue with the surgeon, who must be promptly notified of any doubts, is essential to correctly manage complications.
