    ABSTRACT: Background: Obesity is associated with high morbidity and represents an increasing health care problem worldwide. Laparoscopic sleeve gastrectomy (LSG) has been used effectively for weight loss and co-morbidity remission. In this retrospective study, we evaluated cardiac reverse remodeling at medium-term follow-up by echocardiography, the amount of cardiovascular medications, and the impact of co-morbidities after sleeve gastrectomy. Methods: Altogether, 16 obese patients (4 men, 12 women; 46.4 ± 10.3 years) underwent complete clinical evaluation, laboratory tests, and color Doppler/tissue Doppler imaging echocardiography preoperatively and 12-20 months after bariatric surgery. Results: Body weight (mean body mass index) was significantly reduced (from 44.8 ± 8.0 to 31.2 ± 7.8 kg/m2; p = 0.001). Lipid profile significantly improved: total cholesterol and triglycerides decreased (respectively: 215.5 ± 53.8 vs. 205.3 ± 46.6 mg/dl and 184.9 ± 109.3 vs. 116.1 ± 49.9 mg/dl, both p ≤ 0.05), and high-density lipoprotein increased (43.1 ± 10.9 vs. 51.4 ± 12.8 mg/dl, p = 0.005). Systolic blood pressure significantly decreased (from 133.0 ± 17.1 to 120.6 ± 13.7 mmHg; p = 0.04). Diabetes remission was complete in five of six patients (83%) and sleep apnea in four of five (80 %). Echocardiography showed significantly reduced interventricular septum and posterior wall thickness (11.3 ± 1.8 to 9.4 ± 2.1 mm and 10.4 ± 1.7 to 8.6 ± 1.9 mm, respectively; both p < 0.007) and reduced left ventricular mass (absolute value and indexed by height, respectively: 222.41 ± 78.2 to 172.75 ± 66.3 g (p = 0.003) and 55.9 ± 14.3 to 43.8 ± 17.2 g/m(2.7) (p = 0.0004). Antihypertensive drug intake was significantly reduced (p = 0.03), as shown by the 10-year Framingham Risk Score (from 14.2 ± 9.3 to 8.3 ± 9.5%, p = 0.003). Conclusions: Sleeve gastrectomy is associated with marked improvement in terms of weight loss, lipid profile, type 2 diabetes, sleep apnea, hypertension, and left ventricular hypertrophy, with a significantly reduced Framingham Risk Score.

    ABSTRACT: Background: Gastroesophageal reflux disease (GERD) with or without hiatal hernia (HH) is now recognized as an obesity-related co-morbidity. Roux-en-Y gastric bypass has been proved to be the most effective bariatric procedure for the treatment of morbidly obese patients with GERD and/or HH. In contrast, the indication for laparoscopic sleeve gastrectomy (SG) in these patients is still debated. Our objective was to report our experience with 97 patients who underwent SG and HH repair (HHR). The setting was a university hospital in Italy. Methods: From July 2009 to December 2011, 378 patients underwent a preoperative workup for SG. In 97 patients, SG was performed with HHR. The clinical outcome was evaluated considering GERD symptom resolution or improvement, interruption of antireflux medications, and radiographic evidence of HH recurrence. Results: Before surgery, symptomatic GERD was present in 60 patients (15.8%), and HH was diagnosed in 42 patients (11.1%). In 55 patients (14.5%), HH was diagnosed intraoperatively. The mean follow-up was 18 months. GERD remission occurred in 44 patients (73.3%). In the remaining 16 patients, antireflux medications were diminished, with complete control of symptoms in 5 patients. No HH recurrences developed. "De novo" GERD symptoms developed in 22.9% of the patients undergoing SG alone compared with 0% of patients undergoing SG plus HHR. Conclusion: SG with HHR is feasible and safe, providing good management of GERD in obese patients with reflux symptoms. Small hiatal defects could be underdiagnosed at preoperative endoscopy and/or upper gastrointestinal contrast study. Thus, a careful examination of the crura is always recommended intraoperatively.

    ABSTRACT: Several studies have demonstrated a high rate of type 2 diabetes mellitus (T2DM) resolution after sleeve gastrectomy. Different prognostic factors have been hypothesized for T2DM remission after bariatric surgery. Our objectives were to analyze the role of T2DM duration as an independent prognostic factor for remission. From January 2008 to September 2010, 56 obese patients with T2DM underwent sleeve gastrectomy. Group A consisted of 16 patients who had lived with T2DM for >10 years (12 women and 4 men, mean body mass index 42.7 kg/m2). Group B included 40 obese patients who had lived with T2DM for <10 years (29 women and 11 men, mean body mass index 44.9 kg/m2). In group A, 43.7% were treated with oral hypoglycemics, 6.3% with insulin, and 50% with oral hypoglycemics and insulin. In group B, 87.5% were treated with oral hypoglycemics, 5% with dietary therapy, and 7.5% with insulin. The preoperative average glycemia, glycosylated hemoglobin, and C-peptide value was 206.2 mg/dL, 9.5%, and 2.8 μg/L in group A and 134 mg/dL, 7.1%, and 4.5 μg/L in group B, respectively (P < .05 for all). The T2DM remission rate in all 56 patients was 80.3%. However, in group B, the resolution rate was 100%, but in group A, the resolution rate was 31%. Patients without complete remission were more sensitive to lower doses of antidiabetic drugs. Sleeve gastrectomy is effective in the treatment of obese patients with T2DM. The duration of T2DM seems to be of paramount importance as a prognostic factor, with 10 years representing a cutoff between a 100% rate of remission and significantly lower rates of remission.

    ABSTRACT: The prevalence of gastroesophageal reflux disease (GERD) and/or hiatal hernia (HH) is significantly increased in morbidly obese patients. Laparoscopic bariatric procedures such as gastric banding (LGB) and Roux-en-Y gastric bypass have been shown to improve both obesity and reflux symptoms. The aim of this paper is to evaluate the effectiveness of laparoscopic sleeve gastrectomy (LSG) and hiatal hernia repair (HHR) for the treatment of obesity complicated by HH. From October 2008, six patients underwent HHR in addition to LSG. Clinical outcomes have been evaluated in terms of GERD symptoms improvement or resolution, interruption of antireflux medication, and X-ray evidence of HH recurrence. Symptomatic HH was diagnosed preoperatively in four patients. In two additional patients, HH was asymptomatic and it was diagnosed intraoperatively. Prosthetic reinforcement of crural closure was performed in two symptomatic cases with a HH >5 cm. Mortality was nil and no complications occurred. After a mean follow-up of 4 months, GERD symptoms resolution occurred in three patients, while the other patient reported an improvement of reflux. Body mass index had fallen from 43.4 to 36.2 kg/m(2). A small recurrence in the patient with persistence of reflux symptoms has been radiologically reported. Laparoscopic crural closure in addition to LSG could represent a valuable option for the synchronous management of morbid obesity and HH, providing good outcomes in terms of weight loss and GERD symptoms control.
