Abdominal dermolipectomies: early postoperative complications and long-term unfavorable results.

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.

[What is the cost of excision-suture of a skin lesion under local anesthesia? 2-month prospective evaluation in a public sector hospital].

The purpose of this study was to assess the cost of a minimal surgical operation: skin surgery under local anesthesia in the outpatients department. A two-month prospective study was carried out on 149 operations, with a mean duration of 33 minutes. The mean cost of the operation was 434 FF. Although this study is very specific and its results cannot be generalized, it gives a method and an order of magnitude. It shows that it is difficult to save money without decreasing the quality of the operation. The price list of the French national health care system, and the price of the surgeon himself are discussed.

[Congenital giant blue nevus. Apropos of a case].

A case of a three years old girl showing a congenital giant blue nevus, in the neck and the occipital region, is presented. The giant blue nevus was associated to an important cutaneous nevomatosis. The treatment has consisted of an surgical excision of an surgical excision of the main lesion, and operative continuations have been simple. The literature study showed 11 cases of congenital giant blue nevus and demonstrate the high risk of malignancy, and the importance of an early surgical treatment.

[Lipoma of the superficial lobe of the parotid gland. A case report].

We report the case of a patient with a lipoma of the superficial lobe of the right parotid gland. Lipomas of the parotid gland are very rare. They are said to constitute one to two percent of all parotid tumours. Only six cases were found in the recent literature. Preoperative diagnosis is difficult when the physical examination reveals a renitent, well-localized and painless mass. However, magnetic resonance imaging is now the imaging modality of choice to facilitate the diagnosis, but the diagnosis can only be confirmed by histological examination of the tumour. We discuss the value of superficial parotidectomy, while some authors suggest an enucleation of lipomas of the superficial lobe of parotid.

[Natural skin expansion. Applications to the surgery of nevus of the head and neck in children].

The surgical treatment of congenital naevi of the head and neck often require the use of expansion prostheses. The high risk of complications in children such as infection, necrosis, prosthetic exposure, has led the authors to propose a new therapeutic approach, consisting of deferred cutaneous expansion, which uses the skin tension as an expansion motor. This allows repair in one or several surgical phases, of large defect using the skin of the same anatomical unit, with good esthetic results. The authors describe the three main techniques applied to surgery of naevi of the head and neck: simple excision-suture, excision-unfolding and deforming excision.
