Background: The aim of the study was evaluation of the effect of the resected gastric volume (RGV) on weight loss after laparoscopic sleeve gastrectomy (LSG).Methods: This prospective study included 40 morbidly obese patients undergoing LSG. Multi Detector Computed Tomography (MDCT) was used to measure preoperative stomach volume and sleeve volume. The actual RGV was measured after surgery. The primary outcome measure was the relation between RGV and percentage of excess body weight loss (%EBWL) after 3 and 6 months. The secondary outcome was early postoperative complications.Results: The mean preoperative BMI was 43.5±4.3 kg/m2. The actual RGV was substantially correlated with that estimated by CT (r=0.996, p<0.001). The former was significantly larger with a mean deviation of 17.6 cc (95%CI: 12.2-23.0 kg). The actual and CT-estimated RGV were positively correlated with% EBWL after 3 months (r=0.361, p=0.022 and r=0.471, p<0.001, respectively) and after 6 months (r=0.466, p=0.002 and r=0.553, p<0.001, respectively). Percentage of volume reduction was positively correlated with weight reduction after 3 and 6 months (r=0.0.525, p=0.001 and r=0.564, p<0.001, respectively).Conclusions: The resected gastric volume during LSG was significantly correlated with weight reduction after 3 and 6 months of surgery. Sleeve volume was not correlated with early weight reduction. MDCT is a reliable method to measure gastric volume before and after surgery.

The Impact

Introduction: Laparoscopic sleeve gastrectomy is a primary treatment of obesity among older adults and its satisfactory outcomes would be the main reason behind the popularity of this procedure. We aim to evaluate the impact of age on excess weight loss in adult morbidly obese subjects older than 60 years old following LSG.Methods: In this retrospective survey, 3,072 subjects were included in the study that underwent LSG in Erfan Hospital. Screening follow-up period was 12 months. The level of statistical significance was set at P < 0.05. We hired comorbid conditions to avoid bias results including hypertension, diabetes mellitus and dyslipidemia. Results: Of 3072 patients, 1879 cases were females (61.2%) and 1193 subjects were males (38.8 %). Mean %EBMIL of the group 12 months after surgery was 78.9 %. In younger than 60 years old group, mean %EBMIL 12 months postoperative 83 % and patients  over 60 years demonstrated mean %EBMIL 74.9 %. There was an obvious difference among age groups in presence of diabetes mellitus and hypertension in the older group which was more frequent. Conclusion: To sum up, laparoscopic sleeve gastrectomy is safe procedure for older groups. Albeit, %EBMIL was significantly lower in older group compared to younger subjects, but resolution in comorbidities was satisfactory.

Abstract Background The incidence of obesity has been constantly growing and bariatric procedures are considered to be the most effective treatment solution for morbidly obese patients. The results of laparoscopic sleeve gastrectomy (LSG) may differ depending on patient’s age, gender, preoperative body mass index (BMI) and physical activity. Methods The aim of this study was to evaluate age-related differences in the outcome of LSG in terms of weight loss parameters, lipid and carbohydrate profile. The retrospective analysis of 555 patients who had undergone LSG was performed to compare the metabolic outcomes of surgery in individuals < 45 and ≥ 45 years old. Evaluation of weight loss parameters along with selected laboratory data was performed to demonstrate the results of LSG in 2 years follow-up. Results Overall, 238 males and 317 females (43%/57%) with median age of 43 years and median preoperative BMI of 46.41 (42.06–51.02) kg/m2 were analyzed. Patients in both groups presented significant weight loss at 24 months after the surgery with comparable percentage of total weight loss (40.95% in < 45 years old group and 40.44% in ≥ 45 years old group). The percentage of excess weight loss (78.52% vs. 74.53%) and percentage of excess BMI loss (91.95% vs. 88.01%) were higher in patients < 45 years old. However, the differences were not statistically significant (p = 0.662, p = 0.788 respectively). Patients under 45 years old experienced faster decrease in fasting glucose level that was observed after only 3 months (109 mg/dl to 95 mg/dl in < 45 years old group vs. 103.5 mg/dl to 99.5 mg/dl in ≥ 45 years old group, p < 0.001). Both groups presented improvement of lipid parameters during the observation. However, patients < 45 years old achieved lower values of LDL at 3 and 12 months follow-up (115 mg/dl vs. 126 mg/dl, p = 0.010; 114.8 mg/dl vs. 122 mg/dl, p = 0.002). Younger group of patients also showed superior improvement of triglycerides level. Conclusions LSG results in significant weight loss in all patients regardless age. In turn, superior and faster improvement in lipid and carbohydrate profile is achieved in patients under 45 years old.

The Impact

Abstract Introduction: Laparoscopic sleeve gastrectomy (LSG) is a popular weight loss surgery technique, but the impact on esophageal physiology and esophagogastric junction is still debatable. The aim of our study was to evaluate the manometric changes of the lower esophageal sphincter (LES) after LSG in order to indicate LES manometry pre- procedure. Methods: In a prospective study we evaluated clinically, with upper gastrointestinal endoscopy, and high-resolution esophageal manometry 45 morbidly obese patients before, and 6-12 months after LSG. Results: The BMI (body mass index) decreased from 46.28±5.79 kg/m2 to 32.28±4.65 kg/m2 postoperatively (p <0.01), with a reduction of ~14 kg/m2 of BMI, 39.9 (±11.9) kg body weight and 29.9 (± 6.2)% of the TWL (Total Weight Loss index), in a median interval of 7.9 months. Gastroesophageal reflux disease (GERD) prevalence increased from 17.8% to 31.1% postoperatively, with new GERD onset in 22.2%, but mild symptomatology (the median GERDHRQL score increased from 1.56 to 2.84 points). Postoperatory reflux was associated with lower esophageal sphincter (LES) hypotonia, shortening of LES length and IIGP (increased intragastric pressure). Hiatal hernia repair rate was 17.8%, and proton pump inhibitor consumption 20%. After weight loss, the 10 cases of esophagitis discovered preoperatively cured, but 3 patients were diagnosed with de novo esophagitis. The prevalence of manometric dysmotility after LSG was 28.9%, lower than before surgery (44.4%). Conclusion: Even if GERD remains the main limitation of LSG, the high-resolution esophageal manometry has proved useful and should be implemented in morbidly obese evaluation protocol, to better select the bariatric procedure.
