RESUMO
BACKGROUND: The intragastric balloon is widely used for weight reduction in obese patients, but results are variable. We describe our results enhancing the importance of a Multidisciplinary Team (MT) taking part in the treatment. METHODS: A retrospective review was done concerning a total of 119 balloons , placed in 116 patients, under endoscopic control and conscious sedation, from May 2001 until August 2006. 49 patients were prepared and recommended to be followed by a MT in a physical unit, at least every 15 days during 6 months. 67 were indicated and followed by other colleagues, without MT. Removal was performed 6 months later. RESULTS: Concerning our 49 patients, mean age was 38, 1 years, 31 female and 18 males, with BMI ranged between 32 and 63, average of 42. The average decrease of weight excess was 31, 85% (-4, 45-80, 4%), and the BMI diminished 5,3 points (from 13,6 to gain of 0,9). The treatment failed in 34,6 % of our patients -including 4 patients lost of follow-up (8, 16%)-, compared with 53, 8% of patients without structured MT for selection and follow-up. Physical exercise enhanced markedly the results with 45, 8% of excess of weight loss in women and 39, 7% in males, compared with 14, 6 and 15, 6% in patients who didn't follow the program. The weight loss was mostly fat mass, 89,9% in men and 75,6% in women.- The results maintenance was obtained in 40% of patients one year later. There were no major complications; one balloon had to be removed at 3 weeks because of intolerance, another at 5 months because of gastroesophageal reflux. CONCLUSIONS: BIB is an effective help to achieve a short term weight loss in obese patients; nevertheless, good and long lasting results will depend on the modification of life style obtained by a multidisciplinary approach.

Obesity is considered a chronic and epidemic illness, hece difficult to treat. As conservative treatment has a high rate of failure, and considering morbimortality and sequels of surgery, less invasive techniques appeared to contribute to the treatment of this illness. The most implanted technique nowadays is the Intragastric Balloon, considered more efficient as conservative treatments and with less risks tan surgery, but having today a lack of consensus on indications and few information on his limitations, while its apparition in medias promote an important expansion in the 4 last years. In this publication, we do a critical revision, and describe limitations of this treatment, based on the evidences given by literature. We conclude this revision with some recommendations concerning the technique and indications, material and human requiring, need of a Multidisciplinary Team, as well as an adequate control and following.

With an increased prevalence of obesity in developed countries, associated chronic diseases rise in a parallel way. Morbidity secondary to overweight and obesity include type 2 diabetes, dislipemia, hypertension, heart disease, cerebrovascular disease, cholelithiasis, osteoarthritis, heart insufficiency, sleep apnoea, menstrual changes, sterility and psychological alterations. There is also a greater susceptibility to suffer some types of cancer, infections, greater risk of bacteremia and a prolonged time of wound healing after surgical operations. All these factors indicate that obesity exerts negative effects upon the immune system. Immune changes found in obesity and their possible interrelations are described in this article. Changes produced during obesity affect both humoral and cellular immunity. It is known that adipose tissue, together with its role as energy reserve in form of triglycerides, has important endocrine functions, producing several hormones and other signal molecules. Immune response can be deeply affected by obesity, playing leptin an important role. Properties of leptin, alterations of leptin levels in different situations and its changes with different medical and surgical therapies for obesity are described in this article.

PROPOSAL: Tumoural disease leads to multifactorial cancerous cachexia. There are still few data available on the onset of this syndrome in operable patients, despite the repercussions on prognosis and the indication of nutritional support. GOAL: In this prospective study, we are considering the assessment of nutritional status in the light of the Chang protocol in with gastrointestinal tumours patients, as well as the possible differences depending on the location of the tumour, its progress, and the onset of septic complications. With this approach, we attempt to specify the indication of postoperative nutritional support. MATERIALS AND METHOD: The nutritional assessment protocol existing in the Department was reviewed as applied to 105 patients affected by oesophageal, gastric, pancreatic and colo-rectal cancer. This protocol included the ideal weight percentage (%IW), tricipital fold (TSF), arm muscle circumference (AMC), total albumin and lymphocytes (Chang protocol), as well as urea nitrogen. The database used was created in File Maker Pro running on a Macintosh computer and supported by the StatView programme for the statistical analysis of the results. RESULTS: There were 61 colo-rectal, 18 gastric, 17 oesophageal and 9 pancreatic carcinomas. There was some degree of malnutrition in 52.4% of patients but it was not severe in any case. An outstanding result is the percentage of ideal weight in excess of 100% on average in all of the groups, with little variation in the arm muscle circumference, as is the lower tricipital fold in the oesophageal and pancreatic cases. Albumin was significantly lower in gastric carcinoma cases and lymphocytes showed a correlation with the progress of the tumour and also with the onset of septic complications. The excretion of urea nitrogen did not reveal significant differences. In stages I and II, the patients were normally nourished or with marasmus, so that the only malnutrition found was of the kwashiorkor type and combined with stages III and IV. CONCLUSIONS: There is 52.4% of malnutrition in our surgically resectable digestive oncology patients using the Chang protocol, not susceptible of preoperative renourishment. This is found irregularly depending on the location and stage of the tumour. The total lymphocytes prior to surgery represented an independent variable which correlated with septic complications.

A correct treatment of obesity needs a program of habits modification regardless of the selected technique, especially if it is minimally invasive as the intragastric balloon (BIG). The adherence of the obese patients with regard to recommended drugs measures to medium- and long-term is less than 50%. Given that the results obtained using the technique of gastric balloon must be seen influenced by adherence to the modification of habits program and its fulfillment, we reviewed series published in attention to the program proposed with the BIG. The series published to date provide few details about the used Therapeutic Programs as well as the adherence of patients to them, and even less concerning the Monitoring Plan and the loyalty of the patient can be seen. We conclude the convenience to agree on a follow-up strategy, at least the 6 months during which the BIG remain in the stomach.

INTRODUCTION: Obesity is a chronic disease for which several modalities of treatment are investigated today. One of them is the set of minimally aggressive techniques that have been added to the intragastric balloon. OBJECTIVE: To review the minimally invasive techniques described in the last years for the treatment of obesity. MATERIAL AND METHOD: It consisted in reviewing the bibliography through the habitual finders, in addition to the obtained data of the companies. They are classified in restrictive and malabsortive, and the restrictive are divides in mechanical or functional restriction. RESULT: Between mechanical restrictive the classified as we included in the restrictive emergent techniques the adjustable intragastric balloon, the intragastric prosthesis, the vertical endoluminal gastroplasty and the transoral gastroplasty. In order to obtain a functional restriction, we have the gastric pacemaker and the botulinic toxin. And finally, the endoluminal duodenojejunal bypass is described as a malabsortive technique. DISCUSSION: With less than 10 years of existence, it seems that the described techniques compensate their smaller effectiveness compared to the surgical techniques, with the absence of substantial modifications in the anatomy of the alimentary tract. None of these techniques is free of risks and complications.

INTRODUCTION: Intra-gastric balloon (IGB) is an invasive, temporary, non-surgical technique for the treatment of obesity. Its outcomes mainly depend on the patient's collaboration. OBJECTIVE: The aim was to adapt the informed consent used for bariatric surgery to a method that has especial characteristics. MATERIALS AND METHODS: We used the informed consent proposed by ASAC for bariatric surgery and 8 statements related to IGB included in the WESTLAW ES database. RESULTS: The review of the statements defines the IGB treatment as a curative-intended and non-satisfactive therapy with an obligation of the means used, but not the outcomes, by the treating physician. Moreover, the obligations of providing a correct and complete information -which includes the dietary regime- should be observed, as well as the possible therapeutic alternatives and finally, the proceeding used should be in written. CONCLUSIONS: The informed consent is a medico-legal document which content should consider the latest jurisprudence on the minimally invasive techniques for the treatment of obesity.
