Special Issue Information

Dear Colleagues,

Obesity is currently considered a global epidemic condition, and bariatric/metabolic surgery has emerged as an option for achieving significant and durable weight loss in the treatment of clinically severe obesity.

There is increasing demand for bariatric/metabolic surgery worldwide; in fact, thousands of bariatric procedures are currently being performed around the world with exponentially increasing trends and outcomes.

Over the years, much research has been performed in this field, generating a high degree of knowledge on the effect of bariatric procedures on obesity comorbidities and its effectiveness over the time. In addition, new procedures have been developed and have changed the face of modern bariatric surgery.

The aim of this Special Issue is to provide an overview of recent advances in the field of bariatric surgery. Therefore, we encourage researchers in the field of bariatric surgery to submit an original article (no animal research) or review to this Special Issue (case reports and short reviews will not be accepted).

Background: Obesity is associated with a reduced life expectancy of 5 to 20 years, depending on the severity of the condition and the presence of comorbidities. Beyond first- and second-line interventions such as lifestyle changes, pharmacotherapy, which includes appetite suppressants, drugs that reduce fat absorption or regulate neurohormonal pathways, and endoscopic procedures, bariatric surgery is currently considered one of the most effective long-term interventions for severe obesity. This exploratory study investigates the psychological functioning of bariatric surgery candidates in the preoperative phase, aiming to identify risk factors and potential predictors of response to surgery in an Italian sample. Methods: This is a retrospective, observational study with follow-up. Participants, evaluated between September 2021 and September 2022 at Messina University Hospital, were recontacted approximately one year after surgery for re-evaluation. Of the 97 initial patients, 33 agreed to complete online questionnaires for follow-up. Results: The baseline data showed no significant differences between men and women in psychological assessments. In the subgroup that completed the follow-up, significant changes were observed, including a reduction in BMI and an increase in the discomfort index (Body Uneasiness Test) post-surgery, with large effect sizes in both cases. However, despite these changes, the regression analysis revealed that preoperative BMI values were not directly related to postoperative body image difficulties. These findings suggest a limited psychological impact of bariatric surgery, emphasizing the need for tailored psychological interventions to address these issues. Conclusions: While the intervention confirmed its effectiveness in reducing BMI, improvements in psychological well-being were less pronounced. In particular, a significant increase in body image concerns (PSDI) emerged after surgery, suggesting the need to address body-related distress in post-surgical care. These findings may suggest multidisciplinary approaches that integrate physical and psychological interventions may be needed to maximise long-term benefits. Further research should explore strategies to enhance patient awareness of treatment options, body image issues, and potential complications. These results should be interpreted with caution considering the limitations associated with this study such as a small sample size, lack of a control group, and the use of self-report and online methods to gather data, among others.

Background/Objectives: In metabolic bariatric surgery, structured follow-up protocols may play an essential role in achieving optimal patient outcomes. This study aims to report postoperative biochemical outcomes in a cohort of post-bariatric patients who underwent a structured follow-up protocol. Methods: This retrospective study included patients who underwent metabolic bariatric surgery and completed a one-year follow-up at Cannizaro Hospital from October 2022 to May 2024. Anthropometric, clinical, and laboratory data were collected for each patient at five different timepoints: baseline, 1, 3, 6, and 12 months post-surgery. All data were organized into a database and analyzed through descriptive statistics. Results: The study cohort (n = 80) showed a follow-up adherence equal to 97.5%. The mean value of BMI decreased from 42 to 27 one year after surgery. Lipid profiles improved, with significant reduction in total cholesterol and triglycerides and increase in HDL levels; LDL levels decreased initially but at one year returned to baseline. Thyroid hormones TSH and fT3 decreased significantly, while fT4 remained stable. A reduction in hepatic inflammation was observed, as evidenced by the decrease in GGT and transaminase levels. Pancreatic enzymes showed an initial increase but stabilized at the subsequent timepoints. Glycemic control improved, with statistically significant reductions in insulin, HbA1c, and glucose levels, and complete remission of type 2 diabetes mellitus in affected patients. Conclusions: This study shows significant weight loss and improved health outcomes in post-bariatric patients who underwent a structured follow-up protocol, suggesting the potential benefits of metabolic bariatric surgery.
