ABSTRACT

BACKGROUND: Obesity and type 2 diabetes mellitus are associated to inflammatory state, which can be set off by the adipose tissue, once it is a metabolically active organ that can cause a chronic mild inflammatory state. AIM: To evaluate the correlation between preoperative C-reactive protein and postoperative complications risk in obese patients (grades II and III) after Roux-en-Y gastric bypass, with and without type 2 diabetes mellitus. METHODS: Between 2008 and 2013 were analysed 209 patients (107 with diabetes), presenting body mass index >40 kg/m2 or >35 kg/m2 with comorbidities. During the postoperative period, two groups were evaluated: with and without complications. Preoperative ultra-sensitive C-reactive protein was measured by immunonephelometry method. RESULTS: Complications occurred in seven patients (pulmonary thromboembolism, fistula, two cases of suture leak, pancreatitis, evisceration and upper digestive hemorrhage). No statistical significance was found regarding lipid profile and C-reactive protein between patients with and without type 2 diabetes mellitus. When compared to each other, both groups (with and without complications) presented with statistical significance regarding C-reactive protein level (7,2 mg/dl vs 3,7 mg/dl, p=0,016) and had similar weight loss percentage after 3, 6 and 12 months follow-up. CONCLUSIONS: Preoperative C-reactive protein serum level was higher in the group which presented complications after Roux-en-Y gastric bypass when compared to the group without postoperative complications.

ABSTRACT

BACKGROUND: Roux-en-Y gastric bypass (RYGBP) controls obesity and comorbidities. However, there is no consensus on ring placement due to its complications. Surgical ring removal has been the standard approach, despite its inherent morbidity risks. Endoscopic dilation with achalasia balloon is a novel and minimally invasive option. We aimed to evaluate safety and efficacy of aggressive dilation as an outpatient procedure to treat food intolerance after banded RYGBP without stenosis; we also analyzed long-term weight regain. METHODS: This prospective study included 63 patients presenting with more than four vomiting episodes per week. Therapeutic endoscopy with a 30-mm balloon (Rigiflex®) was performed with radioscopic guidance in the first 16 patients (25.4 %). Four dilation sessions were performed in 12 patients (19 %), three in 14 (22.2 %), two in 24 (38 %), and one in 13 (20.6 %). RESULTS: Complete symptom improvement was achieved in 59 patients (93.6 %), partial improvement in 2 (3.2 %), and failure in 2, leading to ring removal by laparotomy. Complications rate was 9.5 %, including three cases of bleeding, two intragastric ring erosions, and one pneumoperitoneum; all treated clinically with no need for reintervention. Mean preoperative body mass index (BMI) was 42.4 kg/m(2) and postoperative (before endoscopic treatment) BMI was 25.3 kg/m(2). At a mean follow-up of 46.1 months after endoscopic intervention, mean BMI was 27.8 kg/m(2). CONCLUSIONS: Aggressive endoscopic dilation for food intolerance is a safe and minimally invasive method that promotes symptom improvement. It avoided reoperation in 96.8 % of patients and led to a low rate of weight regain.

ABSTRACT

BACKGROUND: Metabolic disorders have high correlation with severe forms of nonalcoholic fatty liver disease. However, there is no non-invasive method that promotes its proper stratification and biopsy remains the ideal diagnostic tool. AIM: To evaluate the prevalence of this disease in obese in preoperative period of Roux-en-Y gastric bypass and metabolic factors correlated with liver histopathology. METHODS: From a total of 47 patients, 35 were enrolled in the inclusion criteria and 12 excluded due to liver disease and alcohol intake >80 g/week. Were performed clinical and laboratory evaluation before the surgery and intraoperative liver biopsy . The intensity was ranked in grade of steatohepatitis: I (mild to moderate) and II (diffuse inflammation), III ( periportal fibrosis) and IV (cirrhosis). Were compared the following variables: duration of obesity, body mass index, waist-hip ratio, type 2 diabetes mellitus, hypertension and dyslipidemia. RESULTS: Thirty -five patients (68.6 % women , mean age 37 years) were evaluated. The mean body mass index preoperatively was 53.04 kg/m². Nonalcoholic steatohepatitis was found in 31 patients (88.6 %) and 32.2% were in grade I (n=10), grade II 45.2% (n=14), and 25.6% grade III (n=7). The waist-hip ratio was associated with hepatic steatosis; hypertriglyceridemia was the marker that had best correlation with higher grade; there was no correlation between aminotransferase and intensity of the disease; there was correlation of intensity with factors related to insulin resistance. CONCLUSION: Nonalcoholic steatohepatitis is highly prevalent in morbidly obese patients, but there was no positive correlation between aminotransferases and degree of obesity and liver histopathology. Hypertriglyceridemia and waist-hip ratio were positively correlated with the intensity of disease.
