A retrospective study was done on a population of 258 women who had undergone surgery for abdominal dermolipectomy between January of 1991 and May of 1996. The postoperative complications and flaws seen at long-term follow-up are discussed. The surgical techniques used, with or without lipoaspiration, were the infraumbilical plasty and full plasties with horizontal or inverted T scars. Six types of postoperative complications were noted: hemorrhage in 1.2 percent, lymphorrhea in 10.9 percent, infection in 7 percent, skin necrosis in 6.6 percent, secondary dehiscence of the scar in 2.3 percent, and thromboembolic accidents in 1.2 percent. No significant difference was found in the rate of necrosis development between patients who did and did not undergo lipoaspiration. However, a statistically significant difference was seen in the rate of skin necrosis between the T-type plasty (35.5 percent) and the other two procedures (1.43 percent for infraumbilical plasties and 4.60 percent for full plasties with horizontal scar). With regard to the flaws found at long-term follow-up, the rate of above-scar fat folds and/or dog-ears was 27.9 percent, and the rate of defective scars was 26 percent. No significant difference was found with regard to the rate of flaws. The rate of all secondary surgical procedures was 29.1 percent, but performance of secondary procedures depended on the willingness of the patient and on the surgeon's judgment. Abdominoplasty procedures involve a high risk of early complications. The rate of skin necrosis is clearly augmented in cases of T-type plasty. The need for secondary surgical correction is frequent, and the patient should be reminded of this possibility during preoperative consultation.
Embolization, because of its important specific morbidity, should not be performed as a prophylactic measure, but only in presence of clinical or laboratory signs of bleeding.
The BOF syndrome must be considered as a neurocristopathy at different levels, with a tiny mesencephalo-prosencephalic lesion and a severe rhombencephalic lesion that includes seven consecutive hindbrain segments, from rhombomere 2 to rhombomere 8.
Mathematical models are being developed at a fast rate in industry thanks to computer technology; they are used to simulate motion and deformation over time to test materials and objects in a virtual manner. These modeling techniques are being developed in medicine, but they remain, at this time, in the domain of biomechanical research. We report a mathematical model for cutaneous excision and suture, which we have used to predict the deformations and tensions that result when using four different forms of excision. The results are expressed in numerical and graphic form. The results obtained corresponded with our experience in dermatologic surgery. Uses and limits of this model are discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
