Renal vein thrombosis caused the nephrotic syndrome in a patient with morbid obesity. Pulmonary embolism occurred initially, but not after anticoagulants were administered. Surviving for three years, the patient died of profound uremia and hyperosmolar coma. At autopsy, membranous glomerular changes were found. Conclusive exclusion of renal vein thrombosis in the morbidly obese patient with nephrotic syndrome appears advisable.

A modification of Mason's vertical banded gastroplasty for morbid obesity is presented, along with experience from 62 treated patients. The modification consists of vertical separation of the reservoir and gastric cavities by division of the gastric wall with a linear cutter and use of a serosal patch to prevent leakage to the abdomen. No breakdown of the vertical suture line occurred. The one major complication was a posterior esophageal injury. Subcutaneous wound infection occurred in two patients. There was no pulmonary embolism and no death. The average weight loss at 1 year postoperatively was 40 kg from the initial body weight, or 61.5% of the excess weight. The body mass index at 1 year had fallen from 47 to 32.45.

A diagnosis of paradoxical cerebral embolus (PCE) was made in five patients aged 31 to 62 years who sustained eight cerebral ischemic events. No patient had evidence of primary carotid system or left heart disease. A probe-patent foramen ovale was the presumed mechanism in four patients, and an unsuspected congenital atrial septal defect was found in the fifth patient. Clinically apparent pulmonary emboli or venous thrombosis preceded the cerebral event in only one instance. Review of the literature reveals a high mortality with PCE. However, careful clinical search for this lesion may be rewarding: four of our five patients survived. One should consider PCE in any patient with cerebral embolus in whom there is no demonstrable left-sided circulatory source. This principle applies particularly if there is concomitant venous thrombosis, pulmonary embolism, or enhanced potential for venous thrombosis due to, for example, morbid obesity, use of hormonal birth control pills, prolonged bed rest (especially postoperatively), or systemic carcinoma.

Patients with morbid obesity have high rates of sudden, unexpected cardiac death. The mechanism of death in these patients is uncertain. Twenty-eight patients with morbid obesity (22 sudden cardiac deaths, 6 unnatural deaths) were compared to 11 age-matched nonobese patients with traumatic deaths. Heart weight, left ventricular cavity diameter, left and right ventricular wall thickness, ventricular septal thickness, epicardial fat thickness, and extent of coronary artery atherosclerosis were determined; myocyte size, nuclear size, and degree of interstitial fibrosis were calculated morphometrically. Mean heart weights in the patients with morbid obesity were increased but remained constant as a percentage of body weight. Of the gross parameters, only heart weight and left ventricular cavity size were independent predictors of obesity. Of microscopic parameters, only nuclear area was an independent predictor of obesity. Of 22 patients with morbid obesity, dilated cardiomyopathy was the most frequent cause of sudden cardiac death in (10 patients), followed by severe coronary atherosclerosis (6), concentric left ventricular hypertrophy without left ventricular dilatation (4), pulmonary embolism (1), and hypoplastic coronary arteries (1). The cardiomyopathy of morbid obesity is characterized by cardiomegaly, left ventricular dilatation, and myocyte hypertrophy in the absence of interstitial fibrosis. It is the most common cause of sudden cardiac death in these patients.

Morbid obesity causes co-morbidity such as diabetes mellitus, hypertensive heart disease, sleep apnoea, degenerative bone diseases and increased incidence of malignancy. Life expectancy and quality of life are reduced significantly. Without adequate weight loss, treatment of co-morbidity remains symptomatic only. Surgical treatment of morbid obesity is the one therapy promising long-term success, since conservative procedures normally lead to recurrence of overweight. We performed laparoscopic gastric banding on 130 patients between 1.11.95 and 31.10.97. Mean overweight was 63 +/- 12.7 kg (SD), and mean BMI was 46.5 +/- 4.6 kg/m2. The average hospital stay was 5.5 +/- 1.5 days. 4 patients with postoperative pulmonary embolism were treated with oral anticoagulation. We performed 9 (6.9%) reoperations because of pouch dilatation or dorsal slipping with food intolerance in the first series of 70, and none in the second series of 60 patients. Median weight loss after 3 months was 14.7 +/- 4.2 kg, after six months 24.0 +/- 6.6 kg and after 12 months 33.2 +/- 8.5 kg, corresponding to excessive weight loss (EWL) of 55.9 +/- 14.8% in the first year. 14 (70%) of 20 patients with diabetes mellitus normalised and 6 patients with diabetes mellitus normalised and 6 patients showed improved blood sugar levels. All 36 patients with hypertensive heart disease had normalised blood pressure, 60% of them without further medical antihypertensive treatment after median EWL of 36%. Cholesterol levels normalised in 30 (57%) patients and improved in 20 (38%) after 6 months. Laparoscopic gastric banding is a suitable method for reducing weight in morbid obesity patients and provides a better quality of life in a group of patients who are carefully evaluated and followed. Reducing co-morbidity and improving ability to work have a positive economic impact on health care costs.

BACKGROUND: This study concerns 33 patients treated for morbid obesity with the procedure proposed by Scopinaro. Results are reviewed retrospectively in terms of complication rates. METHODS: The group consisted of ten men and 23 women with a mean age of 34 years (range 20-51 years), and a mean BMI of 49.5 kg/m(2) (range 37-77). Adequate attempts at medical management had failed repeatedly. The operative procedure involved a 2/3 partial gastrectomy and biliopancreatic diversion by Roux-en-Y reconstruction 50 cm before the ileocecal valve. In one patient, a cholecystectomy was added. RESULTS: The mean weight loss after 6 months was 18.9% of the initial weight, with mean BMI 41 kg/m(2) (range 29-60). Early complications included four wound infections (15%), while two patients complained of an early dumping syndrome (6%), treated by dietary measures. There were no respiratory infections and no pulmonary embolism, likely as a result of the thoracic epidural anesthesia and high doses of prophylactic heparin used. There was no mortality. As to late complications, nine patients complained of diarrhea due to bacterial overgrowth (27%) and were treated with antibiotic therapy. There were five incisional hernias (15%). Five patients had a peptic ulcer (15%) and required medical treatment. Two patients had acute cholecystitis (6%). One patient had an afferent loop obstruction (3%), requiring reoperation. CONCLUSIONS: Overall, this series of intestinal diversion procedures by the method of Scopinaro had a larger complication rate than generally accepted.

Recent qualms about the safety of aesthetic lipoplasty may be attributable more to support system flaws than to technical process deficiencies. The authors here focus on perfunctory patient monitoring when sedative or analgesic drugs are given, cavalier infiltration of mega-dose lidocaine, cursory intraoperative patient observation by team members with conflicting responsibilities, anesthesia providers unfamiliar with the unique surgical physiology of liposuction, hurried-discharge policies that virtually ignore the residual depressant effects of sedatives and analgesics, and compressive dressings that impair postoperative chest-wall expansion and venous return. Whereas pulmonary embolism remains the leading process cause of morbidity from liposuction, complications from austere resource allocation to dedicated patient monitoring should be largely preventable. Not all lipoplasties require an anesthesia provider but-when heavy sedation, mega-dose lidocaine, or both, are projected-a trained team member dedicated exclusively to patient safety and comfort should be a minimum patient care standard. The potential role of lidocaine cardiotoxicity in tumescent anesthesia is widely underappreciated and that of hypothermia goes mostly unrecognized. These, plus largely preventable or potentially correctable perioperative events such as pulmonary edema, fluid imbalance, or improperly administered sedative and analgesic drugs, demand upgrading and expansion of monitoring, resuscitative, and recuperative facilities in physician offices. In fact, ASPS guidelines urge that anesthesia services be engaged for dedicated patient care whenever "major" liposuction or conscious sedation is projected, because liposuction is neither as benign nor as simple a procedure as heretofore reputed. To assess objectively the operative and anesthetic risk of obesity, document body mass index for the preoperative record; morbid obesity (body mass index >/= 35.0), for instance, is a known risk multiplier for sedatives and analgesics. Other system issues such as the dynamic profile of high-dose lidocaine pharmacokinetics, the deportation of fat globules in the bloodstream, and the incidence of intraoperative hypothermia remain as unresolved topics for interdisciplinary, multi-institutional clinical research.

Risk factors and prophylaxis for prevention of deep venous thrombosis (DVT) and pulmonary embolism remain controversial in burn patients. From January 1996 through June 1999, we reviewed all adult burn patients admitted to our burn center with the in-hospital diagnosis of DVT and assessed each affected patient for DVT risk factors. There were 8 symptomatic DVTs and 2 pulmonary embolisms detected in 327 adult burn patients (2.4% incidence). No DVT patient had the risk factors of morbid obesity, previous DVT, congestive heart failure, or neoplastic disease. One patient was older than 65 years. All of the DVTs occurred in veins draining a burned extremity. Seven of 8 patients had burn wound infections as complications. Burns on the extremity developing the DVT as well as the diagnosis of a burn wound infection were significant risk factors for DVT formation. These findings prompt us to consider routine screening for DVT in burn patients with these risk factors.

The purpose of this report was to describe clinical and ultrasound findings associated with venous thromboembolism of the lower extremities and pulmonary embolism observed in our department with special emphasis on the utility of venous ultrasound in the diagnosis of venous thromboembolism. Between January 1, 1998 and December 31, 1999, a total of 47 venous ultrasound procedures were carried out according to the standard technique using a Logic 400 MD system (General Electric). Deep venous thrombosis was diagnosed in 18 cases (38.3%). There were 10 men and 8 women with a mean age of 46 years (range, 24 to 71 years). Thrombosis involved the internal saphenous, popliteal, or sural vein in 12 cases, the common or deep femoral vein in 4, and the external iliac vein in 2. The most common risk factors observed in our series were surgery, predisposing conditions, history of venous thrombosis and morbid obesity (66.8% of case). Prolonged periods of bed confinement and neoplasm (lower extremity Kaposi's disease) were more uncommon (22.2%). Pulmonary embolism occurred during the observation period in six cases (33.3%) including 3 (50%) that were fatal. Based on these findings it can be concluded that although its incidence is relatively low in black African patients at risk, thromboembolic disease is often fatal and requires routine preventive treatment using heparin.

A 1991 National Institutes of Health Consensus Conference concluded that severely obese adults could be eligible for bariatric surgery if they had a body mass index (BMI) > or =35 kg/m(2) with or > or =40 kg/m(2) without obesity comorbidity. It was thought at that time that there were inadequate data to support bariatric surgery in severely obese adolescents. An estimated 25% of children in the United States are obese, a number that has doubled over a 30-year period. Very little information has been published on the subject of obesity surgery in adolescents. Therefore we reviewed our 20-year database on bariatric surgery in adolescents. Severely obese adolescents, ranging from 12 to less than 18 years of age, were considered eligible for bariatric surgery according to the National Institutes of Health adult criteria. Gastroplasty was the procedure of choice in the initial 3 years of the study followed by gastric bypass, which was found to be significantly more effective for weight loss in adults. Distal gastric bypass (D-GBP) was used in extremely obese patients (BMI > or =60 kg/m(2)) before 1992 and long-limb gastric bypass (LL-GBP) was used for superobese patients (BMI > or =50 kg/m(2)) after 1992. Laparoscopic gastric bypass was used after 2000. Thirty-three adolescents (27 white, 6 black; 19 females, 14 males) underwent the following bariatric operations between 1981 and June 2001: horizontal gastroplasty in one, vertical banded gastroplasty in two, standard gastric bypass in 17 (2 laparoscopic), LL-GBP in 10, and D-GBP in three. Mean BMI was 52 +/- 11 kg/m(2) (range 38 to 91 kg/m(2)), and mean age was 16 +/- 1 years (range 12.4 to 17.9 years). Preoperative comorbid conditions included the following: type II diabetes mellitus in two patients, hypertension in 11, pseudotumor cerebri in three, gastroesophageal reflux in five, sleep apnea in six, urinary incontinence in two, polycystic ovary syndrome in one, asthma in one, and degenerative joint disease in 11. There were no operative deaths or anastomotic leaks. Early complications included pulmonary embolism in one patient, major wound infection in one, minor wound infections in four, stomal stenoses (endoscopically dilated) in three, and marginal ulcers (medically treated) in four. Late complications included small bowel obstruction in one and incisional hernias in six patients. There were two late sudden deaths (2 years and 6 years postoperatively), but these were unlikely to have been caused by the bariatric surgical procedure. Revision procedures included one D-GBP to gastric bypass for malnutrition and one gastric bypass to LL-GBP for inadequate weight loss. Regain of most or all of the lost weight was seen in five patients at 5 to 10 years after surgery; however, significant weight loss was maintained in the remaining patients for up to 14 years after surgery. Comorbid conditions resolved at 1 year with the exception of hypertension in two patients, gastroesophageal reflux in two, and degenerative joint disease in seven. Self-image was greatly enhanced; eight patients have married and have children, five patients have completed college, and one patient is currently in college. Severe obesity is increasing rapidly in adolescents and is associated with significant comorbidity and social stigmatization. Bariatric surgery in adolescents is safe and is associated with significant weight loss, correction of obesity comorbidity, and improved self-image and socialization. These data strongly support obesity surgery for those unfortunate individuals who may have difficulty obtaining insurance coverage based on the 1991 National Institutes of Health Consensus Conference statement.
