Malignant ventricular dysrhythmias in a patient with isovaleric acidemia receiving general and local anesthesia for suction lipectomy.

We report the occurrence of severe ventricular arrhythmias in a patient with isovaleric acidemia during general anesthesia for suction lipectomy. The timing of events and character of the ECG changes are most consistent with bupivacaine toxicity after subcutaneous injection of tumescence solution containing this local anesthetic. The patient had previously documented carnitine deficiency, a condition which, we speculate, may lower the threshold for bupivacaine induced cardiotoxicity. We review clinical considerations in isovaleric acidemia and conclude that the use of bupivacaine in these patients probably should be avoided.

Acute and 1-month effect of small-volume suction lipectomy on insulin sensitivity and cardiovascular risk.

OBJECTIVE: The most common surgical procedure for obesity is liposuction, the majority of which are small-volume procedures. The effect of large-volume liposuction on cardiovascular risk and insulin sensitivity has been variable. This study was performed to evaluate the effect of the more common, smaller-volume liposuction on insulin sensitivity, inflammatory mediators, and cardiovascular risk factors. SUBJECTS AND STUDY DESIGN: In all, 15 overweight or obese premenopausal women underwent metabolic evaluation prior to, 1 day following and 1 month following suction lipectomy of the abdomen. Metabolic evaluation included assessment of free fatty acids, glucose, insulin, insulin sensitivity by frequently sampled i.v. glucose tolerance test, and adipokines (IL-6, angiotensin II, leptin, PAI-1, adiponectin, and TNF-alpha). RESULTS: Free fatty acids did not change acutely although there was an almost 30% decrease in free fatty acids at 1 month. Fasting insulin levels decreased at one month from 8.3 +/- 1.1 to 5.6 +/- 1.3 microU/ml (P = 0.006). Insulin sensitivity by i.v. glucose tolerance test did not change at 1 month (4.0 +/- 0.8 to 5.0 +/- 0.7, P = 0.12) although with subgroup analysis insulin sensitivity improved in obese but not overweight participants. Several adipokines worsened acutely (IL-6 increased 15 fold and angiotensin II increased 67%), but there was no change in PAI-1, and other adipokines (adiponectin, leptin, and TNF-alpha) decreased. At the 1-month follow-up, all adipokines were similar to baseline. CONCLUSION: This study provides little evidence supporting increased or decreased cardiovascular risk although there is evidence supporting improved insulin sensitivity at one month, especially in obese women.

Intraoral transmental suction lipectomy.

Intraoral transmental suction lipectomy (TMSL) is performed by entering the suction canula through the chin osteotomy/ostectomy gap into the sub- and/or supraplatysmal fat tissue layers. The aim of the study was to know patients' and operators' satisfaction with the procedure, and to know the kind and frequency of the complications. Twenty patients were consecutively treated and reviewed after a minimum of 5 years. All were satisfied with the overall results. It proved difficult to differentiate between the results of the liposuction and those of the genioplasty and/or orthognathic profile correction. From a surgeon's point of view, 11 showed excellent, nine good and one moderate results. Complications included one local subcutaneous infection, four transient neurosensory disturbances at the lower lip and two marginal branch weaknesses. All complications were resolved by the time of the long-term follow-up appointment. TMSL offers the psychological advantage of being performed without skin incision. Cosmetic results and complications are similar to those obtained with the transcutaneous liposuction techniques.

Stimulatory effect of voluntary exercise or fat removal (partial lipectomy) on apoptosis in the skin of UVB light-irradiated mice.

Earlier studies indicated that high dietary fat and obesity are associated with an increased risk of cancer at several organ sites in experimental animals and in humans. In a recent study we found that voluntary running wheel exercise decreased body fat and inhibited ultraviolet B light (UVB)-induced carcinogenesis in the epidermis of SKH-1 mice. In the present study we demonstrate that voluntary running wheel exercise stimulated UVB-induced apoptosis in the epidermis by a p53-independent mechanism, and voluntary exercise also stimulated apoptosis in UVB-induced tumors in tumor-bearing mice. Exercise had no effect in non-UVB-treated epidermis or in areas of the epidermis away from tumors in tumor-bearing mice. In addition, we found that removal of the parametrial fat pads (partial lipectomy) 2 weeks before UVB irradiation enhanced UVB-induced apoptosis. The results of our studies suggest that fat cells secrete substances that inhibit apoptosis in cells with DNA damage and possibly also in tumors. Our results help explain why exercise or various dietary regimens that decrease tissue fat inhibit carcinogenesis.

Suction-assisted lipectomy for lipodystrophy.

Lipodystrophy resulting from HIV disease or the antiretroviral therapy used to treat it is a common complication. We report on the treatment of cervical lipohypertrophy ("buffalo hump") with suction-assisted lipectomy in six patients.

Surgical repair of posttraumatic deformities with selective suction lipectomy.

From June 1982 to June 1984, selective suction lipectomy was performed successfully in 9 patients with posttraumatic fat deposit deformity. Seven patients had minor deformities that were repaired under local anesthesia on an outpatient basis. Two other patients sustained thigh deformities after a moped and a skiing accident, respectively, and were operated on under general anesthesia. Encouraging results have been obtained using the blunt dissection technique of Illouz. Indications for use of this technique and probable future developments are also discussed.

Elimination of lymphangioma circumscriptum by suction-assisted lipectomy.

Lymphangioma circumscriptum presents as cutaneous vesicles or skin tags that drain lymphatic fluid. Deep, sequestered lymphatic cisterns encircled by smooth muscle are thought to be the cause of the skin manifestations, and selective resection of the deep cisterns, not the involved overlying skin, has been suggested as the treatment of choice. We report a successful treatment of lymphangioma circumscriptum using suction-assisted lipectomy to obliterate the deep lymphatic cisterns and their vertical channels communicating to the skin.

Prevention and treatment of waves after suction lipectomy.

Suction lipectomy using a cannula to create multiple tunnels leaves multidirectional subcutaneous scars that, if deep enough, do not modify the appearance of the skin. The postoperative appearance of waves is due to either subcutaneous fat deficiency or to a relative excess of skin. Easy to distinguish clinically, these two kinds of waves may be avoided by a vertical aspiration technique. Fatty defects may be filled with fat obtained from the margins of the defect or from a distant site. The condition of excess skin must be foreseen and the patient warned that a skin resection will be necessary 6 months later.

Correction of saddlebag deformity of the lower eyelids by superficial suction lipectomy.

A simple, quick, and safe method for the correction of eyelid saddlebag deformity is presented. Past techniques involved intricate muscle transposition flaps and extensive dissection. Anatomic dissection clearly demonstrates that the saddlebag deformity is caused by an excess of subcutaneous fat in a well-defined space similar to the fat pads of the upper and lower eyelids. This newly described fat pad lies over the preorbital fibers of the orbicularis oculi muscle and at times extends into the malar area. The technique of superficial suction lipectomy for the removal of eyelid saddlebag deformity is simple and done with local anesthesia on an outpatient basis. Results in multiple patients with follow-up ranging from 1 to 7 years are presented.

Ultrasound-assisted lipectomy using the solid probe: a retrospective review of 100 consecutive cases.

Ultrasound-assisted lipectomy using the solid probe is a predictable and safe method that can yield excellent results. This method is particularly useful and is indicated when the subdermis must be approached to smooth out surface irregularities and/or to stimulate skin retraction. The authors present their method using the solid probe and a retrospective study of their first 100 consecutive cases. The indications for using the solid probe, its advantages and disadvantages, associated complications, and representative cases are presented.

Buried penis release in adults with suction lipectomy and abdominoplasty.

The buried penis in adults who had substantial weight gain was treated with a combination of suction lipectomy of the abdomen and pubic area and the release of the suspensory ligament of the penis and with abdominoplasty with suture anchoring of the pubic and penile skin base dermis to the rectus fascia superiorly. This procedure was performed in 11 patients over the past 10 years with satisfactory results. One patient required additional excess skin excision from the side of the pubic and scrotal area to improve the results.

Cervicofacial rejuvenation using ultrasound-assisted lipectomy.

This article discusses a technique of cervicofacial rejuvenation that involves ultrasound-assisted lipectomy. This method is indicated for those patients who might be early candidates for a rhytidectomy, and/or those with an adipose volume excess in the lower facial and cervical areas. The application of ultrasonic energy stimulates skin retraction and allows for the superficial fat to be more safely accessed than can be accomplished with conventional liposuction methods. This technique, along with a retrospective analysis of the first 26 cases treated with the technique, will be presented in this article.

Lipectomy of the ilio-lumbosacral region.

In the past, several techniques for raising the gluteal mass have been described, all of which were based on dermolipectomies of major or minor extension. The main disadvantage of these dermolipectomies is the visible external scar. The author presents his technique for lipectomy of the ilio-lumbosacral region. It is proposed that multiplanar liposuction in this region lengthens the lumbar lordotic curve and results in upward traction on the buttocks, resulting in a more youthful contour of the region. The article describes a series of 98 patients with lipodystrophy of the ilio-lumbosacral area who underwent liposuction of the region and were highly satisfied with the results.

Blunt liposuction cannula dissection with and without suction-assisted lipectomy in reconstructive surgery.

Efforts continue to expand the role of blunt liposuction cannulae in flap elevation and reconstructive surgery. Suction-assisted lipectomy to reduce the actual volume of fat tissue present may allow the further reach and compressibility of mobilized flaps. These instruments find the safest possible plane for continued undermining dissection even at great distances. Applications yet unknown await discovery.

Partial lipectomy, but not PVN lesions, increases food hoarding by Siberian hamsters.

We tested the inverse relationship between body fat and food hoarding in Siberian hamsters by decreasing or increasing body fat through partial surgical lipectomy (LIPX) or by making obesity-inducing lesions of the paraventricular nucleus of the hypothalamus (PVNx), respectively. We asked three questions. 1) Is food hoarding increased after body fat loss due to LIPX? 2) Is food hoarding decreased after PVNx? 3) Does PVNx affect the hoarding response to LIPX? Hamsters housed in a simulated burrow system increased food hoarding after LIPX followed by a decrease to pre-LIPX levels as body fat was partially compensated through an increase in the mass of their unoperated fat pads. PVNx hamsters had increased body mass and food intake but did not have decreased food hoarding, nor was food hoarding increased by LIPX in PVNx hamsters. The partial body fat compensation by LIPX + PVNx hamsters suggests that the damaged PVN did not cause a general failure to sense energy deficits but did affect the ability to integrate internal and external energy stores.
