Obesity is a growing health, social, and economic issue and became an epidemic, according to recent report of World Health Organization.The only method with scientifically proved efficiency of body mass loss is a surgical treatment. Laparoscopic sleeve gastrectomy (LSG) is recently a leading method in metabolic surgery. There are no standards of operative technique for LSG so far. The influence of technique modification on metabolic effect has not been described clearly.The aim of this study was to evaluate metabolic effects in patients with morbid obesity who underwent various surgical approaches of LSG.The study included 120 patients who were randomly divided into 3 groups: Group I, where bougie size was 32 French (Fr), Group II—36 Fr and Group III—40 Fr. Each group was divided into 2 subgroups, based on the distance of resection beginning from the pylorus—2 or 6 cm. Statistical analysis of: body mass index (BMI), the Percentage of Excess Weight Loss (%EWL), the Percentage of Excess BMI Loss (%EBMIL), levels of glucose and insulin on an empty stomach, glycated hemoglobin (HbA1c), insulin resistance (Homeostatic Model Assessment of Insulin Resistance Index—HOMA-IR), aspartate transaminase (AST), alanine transaminase (ALT), total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), triglycerides (TG), and C-reactive protein (CRP) were under investigation.Statistically significant decrease in body mass, BMI, %EWL, %EBL, glucose, and insulin concentrations has been observed in all studied groups. It was the highest when the smallest calibration tube has been used (32 Fr). Similar results were observed in HOMA-IR and HbA1c levels. Statistically significant decrease of total cholesterol, LDL, and TG concentrations have been observed. Significant increase of HDL in every group has been also noted. Postoperative CRP values were the lowest when the smallest bougie was used.LSG is effective method of obesity treatment. Metabolic effects of LSG are the most noticeable when a small bougie size is used.
A b s t r a c tIntroduction: The worldwide outbreak of morbid obesity forced contemporary medicine to adopt a multidisciplinary approach, which led to the description of metabolic syndrome (MS): a disease with self-aggravating components and one of the most important causes of morbidity and mortality. The need for therapeutic methods provoked development of metabolic surgery, which nowadays give possibilities for safe and effective treatment of all MS aspects simultaneously and improves many obesity-related comorbidities. Aim: To assess the laparoscopic sleeve gastrectomy (LSG) procedure's efficiency in resolving MS components, treating comorbidities and to analyze the influence on certain biochemical markers in 1-year follow-up. Material and methods: The retrospective cohort study of 211 patients after an LSG operation relied on statistical analysis of clinical data collected prospectively in follow-up visits. All applicable guidelines and bioethical recommendations were respected in this study. Results: Assessment of bariatric efficiency proved the LSG operation to be effective in inducing significant weight loss and treating obesity. Analysis on the influence on MS components, such as non-insulin dependent diabetes (NIDDM), arterial hypertension (AH) and dyslipidemia, showed substantial improvement in all observed cases of these diseases. In the present study, follow-up also proved a partial remission inducing effect of this bariatric operation in many comorbidities, especially in chronic obstructive pulmonary disease, obstructive sleep apnea, peptic ulcer disease and depression. A desirable reduction in creatinine, C-reactive protein, uric acid, alanine aminotransferase, asparagine aminotransferase, g-glutamyltransferase serum levels has also been observed during the follow-up. Conclusions: The LSG is an effective method of treatment in all areas of metabolic syndrome, provides a significant positive clinical outcome in obesity-related comorbidities and induces desirable changes in inflammatory, kidney and liver related biomarkers.
Background The most commonly performed bariatric operations are laparoscopic sleeve gastrectomy (LSG) and bypass surgeries (laparoscopic one-anastomosis gastric bypass (OAGB) and laparoscopic Roux-en-Y gastric bypass (LRYGB)), and predicting perioperative morbidity is crucial for early, safe patient discharge. We aimed to determine whether C-reactive protein (CRP) and white blood count (WBC) measured on the first postoperative day predicts perioperative morbidity in the first 30-days after LSG and bypass surgeries. Methods We retrospectively analyzed data for 1400 patients who underwent bariatric surgery in seven bariatric centers from 2014 to 2018. Patients were divided into a complicated group (patients with postoperative complications) and a non-complicated group. We also performed separate analyses for LSG and bypass surgeries. Results Patients were 929 women (66%) and 471 men (34%) with a median age of 42 years (range, 35–51 years); 1192 patients underwent LSG (85%), 120 underwent LRYGB (9%), and 80 underwent OAGB (6%). We performed ROC analyses to set cut-off points, followed by multivariate logistic regressions. CRP > 33.32 mg/L increased the odds ratio (OR) of perioperative complications after LSG 2.27 times, while WBC > 12.15 × 103/μL on postoperative day 1 was associated with a 3.34-times greater or of developing complications. WBC > 13.78 × 103/μL was associated with a 13.34-times higher or of perioperative morbidity in patients undergoing bypass surgeries. Conclusion Even slightly elevated CRP and WBC on postoperative day 1 should alert surgeons to the potential risk of perioperative morbidity.
Laparoscopic sleeve gastrectomy (LSG) is an essential bariatric procedure performed in obese patients, which provides significant weight loss and has a positive impact on obesity-related diseases. However, as with any surgical procedure, it carries the risk of complications. The complications that can arise in patients following LSG are divided into acute (diagnosed within 30 days after the surgery) and late. Early complications that require rapid management include haemorrhage (intraluminal or extraluminal), leak in the staple line, and abscess formation. Late complications include gastric stenosis, nutrient deficiencies, mediastinal pouch migration, and the development or exacerbation of gastroesophageal reflux diseases. In this review, we present the basic information about most common complications following LSG, and their symptoms, diagnostic tools, and management.
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.

Background: Although laparoscopic sleeve gastrectomy (LSG) is considered a safe bariatric procedure in the treatment of obesity, it still involves a risk of developing postoperative complications. Knowledge of risk factors for possible complications would allow appropriate preoperative planning, optimization of postoperative care, as well as early diagnosis and treatment. The aim of this study was to evaluate risk factors for complications after laparoscopic sleeve gastrectomy. Methods: A retrospective study of 610 patients who underwent LSG at a tertiary institution were included in the study through retrospective analysis of the medical data. Complications were categorized as early (<30 days) and late (≥30 days) and evaluated according to the Clavien–Dindo Classification. Results: Early complications were observed in 35 patients (5.74%) and late complications occurred in 10 patients (1.64%). Independent risk factors of early complications after laparoscopic sleeve gastrectomy included hypercholesterolemia (OR 3.73; p-value = 0.023) and smoking (OR = 274.66, p-value < 0.001). Other factors that may influence the postoperative course are length of hospital stay and operation time. Smoking, peptic ulcer diseases and co-existence of hiatal hernia were found to be an independent predictors of late complications. Conclusions: Smoking is associated with the higher risk of both, early and late complications, while hypercholesterolemia with only <30 days complications after laparoscopic sleeve gastrectomy.
