Efeitos da cirurgia bariátrica sobre a síndrome metabólica

Study of the clinical and histopathological repercussions of the "omental band" in dogs' stomach

PURPOSE

To evaluate the efficacy of the "omental band" as a bariatric surgical technique.

METHODS

A sample of 35 dogs was studied. The Test Group was composed by 20 dogs. Of these, six were observed by 10 days, six were observed by 20 days and eight were observed by 30 days of post-operatory. The Control Group was composed by 15 dogs. Of these, five were observed by 10 days, five were observed by 20 days and five were observed by 30 days of post-operatory. The weight loose was the variable utilized to the evaluation of the efficacy of the surgical technique described in this study, once all of the dogs were weighted in precision balance before the surgical act and at the end of the post-operatory observation period.

RESULTS

At the end of the study it was observed that the weight loose of the dogs submitted to the "omental band's" surgical technique was meaningfully higher in comparison with the dogs of the Control Group at the end of the post-operatory observation period.

CONCLUSION

The surgical technique of the "omental band" showed effective in dogs, once has proposed a meaningfully weight loose.

GLYCEMIC BEHAVIOR IN 48 HOURS POSTOPERATIVE PERIOD OF PATIENTS WITH TYPE 2 DIABETES MELLITUS AND NON DIABETIC SUBMITTED TO BARIATRIC SURGERY

Although there is no indication for surgery taking only into account the glycemic condition, results have shown that benefits can be obtained in glycemic control with bariatric surgery.

AIM

To compare the glycemic behavior among type 2 diabetic and non-diabetic patients within 48 h after bariatric surgery, and clarify whether there is a reduction in blood glucose level in obese patients with diabetes before the loss of weight excess.

METHODS

Descriptive epidemiological study with prospective cohort design with 31 obese patients undergoing Roux-en-Y gastric bypass and sleeve gastrectomy. The patients were controlled with hemoglucotests in different periods of time: preoperative, postoperative and each 6 h after surgery for 48 h.

RESULTS

Average ambulatory blood glucose in diabetics was 120.7±2.9 mg/dl vs 91.8±13.9 mg/dl in the nondiabetic. After 48 h there was decrease in diabetics to 100.0±17.0 mg/dl (p=0.003), while the non-diabetic group did not change significantly (102.7±25.4 mg/dl; p=0.097). There were no differences between the surgical techniques. There were no death.

CONCLUSIONS

Diabetic patients significantly reduced blood glucose after surgery regardless of the use of exogenous insulin or oral hypoglycemic agents.

CLINICAL AND NUTRITIONAL ASPECTS IN OBESE WOMEN DURING THE FIRST YEAR AFTER ROUX-EN-Y GASTRIC BYPASS

BACKGROUND

Clinic care for morbid obesity is not very effective. Bariatric surgery is being considered the best way of intervention for this kind of obesity.

AIM

Evaluate the clinical and nutritional evolution during the first year of obese women submitted to Roux-en-Y gastric bypass.

METHOD

Retrospective series non-concurrent with 61 women. The variables were weight, BMI, weight loss percentage, loss of excessive weight percentage, waist circumference, hip circumference, lipid profile, daily use of supplements, practice of physical exercise, occurrence of sickness, nausea, constipation, diarrhea, asthenia, alopecia, dry skin, cramps and brittle nails.

RESULTS

They presented significant weight and IMC reduction as well as improvement in their lipid profile, in all consultations. After one year they presented 36,6% loss of the initial weight and 75% loss of excessive weight. The waist circumference also presented a considerable reduction on all the moments, decreasing from 122,1±13,4 cm to 94,1±10,6 cm. Regarding the intercurrences, the most frequent were alopecia, asthenia, dry skin and cramps.

CONCLUSION

The Roux-en-Y gastric bypass was effective in promoting and maintenance weight loss during the period of the first postoperative year.

Bariatric surgery reverses metabolic risk in patients treated in outpatient level

Background

The conventional treatment of obesity presents unsatisfactory results on weight loss and its long-term sustainability, therefore bariatric surgery has been suggested as an effective therapy, determining sustainable long-term weight loss, reversal of components of cardiometabolic risk and improved quality and life expectancy.

Aim

To investigate the clinical component of the cardiometabolic risk in patients undergoing bariatric surgery assisted on outpatient basis.

Methods

The sample consisted of 47 patients with ages between 18 and 60 years, 72% females. Diabetes mellitus, hypertension, and dyslipidemia were prospectively evaluated by using the Assessment of Obesity-Related Co-morbidities scale.

Results

Occurred improvement in these co-morbidities within 12 months after surgery. Co-morbidities resolved were greater than those improved.

Conclusion

The study revealed that the Assessment of Obesity-Related Co-morbidities is a system that can be effectively used to quantify the degree of reduction of the severity of the cardiometabolic risk in response to bariatric surgery.
