Introduction: The increasing prevalence of obesity worldwide has raised concerns about its impact on surgical outcomes across various procedures. Laparoscopic cholecystectomy (LC), a common surgical intervention for benign gallbladder disease, is no exception. The relationship between obesity and LC outcomes remains complex and merits further investigation. Aim: This retrospective study aimed to assess the influence of obesity on the safety and surgical outcomes of LC. Material and methods: Patients were divided into 2 groups: those with obesity (body mass index (BMI) = 30 kg/m²) and non-obese controls (BMI < 30 kg/m²). Baseline characteristics, operative duration, hospitalization length, and post-operative complications, categorized by the Clavien-Dindo classification, were evaluated. Results: Among 116 patients with obesity and 176 non-obese controls, differences in age and gender were noted but were not clinically significant. Operative time was longer in the group with obesity. Hospitalization length and adverse event occurrence did not differ significantly. Importantly, post-operative complications showed no substantial differences between the groups, suggesting that obesity may not significantly increase the complication risk in this population. Conclusions: Obesity may not substantially elevate the risk of adverse events or severe complications following LC in this patient population. Careful patient selection, preoperative evaluation, and surgical technique remain crucial. Further research in larger, diverse populations is needed to validate these findings.

Introduction: Despite the clinical benefits of bariatric surgery, some patients have experienced disappointment with their weight loss. Setting realistic expectations is the key to success. Aim: To develop a specific prediction calculator to estimate the expected body mass index (BMI) at 1 year after laparoscopic sleeve gastrectomy (LSG). Material and methods: A retrospective analysis was performed to study 211 patients after primary LSG. Nine baseline variables were analyzed. Least angle regression (LARS) was employed for variable selection and to build the predictive model. External validation was performed on a dataset of 184 patients. To test the accuracy of the model, a Wilcoxon signed-rank test was performed between BMI estimates and the observed BMI. A linear logistic equation was used to construct the online predictive calculator. Results: The model included three variables -- preoperative BMI (β = 0.023, p < 0.001), age (β = 0.005, p < 0.001), and female gender (β = 0.116, p = 0.001) -- and demonstrated good discrimination (R2 = 0.672; adjusted R2 = 0.664) and good accuracy (root mean squared error of estimate, RMSE = 0.124). The difference between the observed BMI and the estimated BMI was not statistically significant (median = 0.737 (-2.676, 3.254); p = 0.223). External validation confirmed good performance of the model. Conclusions: The study revealed a useful predictive model for estimating BMI at 1 year after LSG. The model was used for development of the PREDICT BMI calculator. This tool allows one to set realistic expectations of weight loss at one year after LSG. [ABSTRACT FROM AUTHOR]

Introduction: As obesity has become a major health problem in Poland and bariatric procedures are the best way of treatment, an increasing trend has been observed in Polish bariatric surgery for the last decade. Aim: Our purpose was to provide an updated overview of the bariatric surgical procedures performed in Polish institutions in comparison to the situation in Europe as well as to analyze the trends in Polish bariatric surgery over the last decades. Material and methods: A questionnaire about the number and type of bariatric procedures performed in 2016 was sent to all Polish surgical departments. Two hundred and sixty surgical departments returned the questionnaires. Results: Twenty-seven departments reported having performed bariatric operative or endoscopic procedures in 2016. The total number of procedures reported was 1958, the most popular being the laparoscopic sleeve gastrectomy (LSG). More than 99% of procedures were performed using laparoscopic techniques. The most common operations were: LSG (64.6%, n = 1032) and laparoscopic Roux-en-Y gastric bypass (LRYGB) (18.2%; n = 291), followed by one anastomosis gastric bypass (OAGB) (8.3%; n = 132) and laparoscopic adjustable gastric banding (LAGB) (7.3%; n = 117). Conclusions: Registers of bariatric procedures provide information that helps in planning treatment and predicting possible complications. Adequate reporting of bariatric procedures is necessary to present the importance of the high incidence of obesity and the importance of its treatment. To collect reliable data, a national Polish bariatric surgery registry should be created. [ABSTRACT FROM AUTHOR]
