Relationship Between Serum Apolipoprotein Levels and Weight Loss in Patients Undergoing Sleeve Gastrectomy for Morbid Obesity

The study looks at whether a specific protein in the blood, called apolipoprotein, can predict how much weight a person might lose after sleeve gastrectomy, a surgery for people with severe obesity. We want to find a specific level of this protein that shows which patients are most likely to lose weight successfully after surgery. By identifying this level, we hope to guide doctors in deciding who should have the surgery and who might do better with non-surgical weight loss methods.

Effect of Lidocaine-Dexmedetomidine on Pain, Inflammation, and Oxidative Stress After Bariatric Surgery.

The goal of this randomized clinical trial is to find out whether giving an intravenous lidocaine + dexmedetomidine combination (LIDEX) during laparoscopic bariatric surgery can lower post-operative pain, inflammation, and oxidative stress in adults with obesity. The main questions it aims to answer are: * Pain control: Does LIDEX reduce pain 24 hours after surgery, as measured with the International Pain Outcomes Questionnaire (IPOQ)? * Biomarkers: Does LIDEX lower blood levels of key inflammatory cytokines-interleukin-1 beta (IL-1β), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-α), and interleukin-10 (IL-10)-and oxidative-stress markers-malondialdehyde (MDA), the reduced/oxidized glutathione ratio (GSH/GSSG), superoxide dismutase (SOD), and catalase-compared with the individual drugs or saline placebo? Researchers will compare four groups: lidocaine alone, dexmedetomidine alone, LIDEX, and placebo (saline solution, a look-alike substance that contains no drug) to learn which approach works best. Participants will: * Receive an intravenous infusion of their assigned study drug(s) during surgery. * Provide three small blood samples (before surgery, immediately after, and three hours after). * Complete a short pain questionnaire (IPOQ) 24 hours after surgery.

Midterm Follow up Outcomes of (SASJ) in Management of Morbid Obesity

Obesity is a critical health problem associated with an increased risk of cardiovascular disease, diabetes, and cancers, affecting both the quality of life and life expectancy . The increasing prevalence of obesity and comorbid conditions requires effective treatment and prevention . Previous evidence has demonstrated that bariatric surgery is associated with greater and longer-term weight loss than non-surgical management Thus, in patients with a body mass index of ≥ 40 or ≥ 35 kg/m2 with co-morbidities, bariatric surgery is the most effective treatment option that not only promotes weight loss but also improves comorbid conditions . However, like any surgical procedure, several complications can occur . The development of nutritional deficiencies is a complication which may be life-threatening; therefore, bariatric surgery requires careful consideration . The most frequently performed surgery for obesity worldwide is the laparoscopic sleeve gastrectomy (LSG), the Roux-en-Y gastric bypass (RYGB), and more recently, the one anastomosis gastric bypass (OAGB) . One newly developed weight loss procedure, the single sleeve ileal anastomosis bypass (SASI), has been developed as a modification to Santoro's operation (sleeve gastrectomy with transit bipartition SG + TB) . Since no duodenal division or manual anastomosis is required, the procedure allows easy endoscopic access to the duodenum . noted that SASI has the following advantages over other bariatric procedures: SASI has a shorter operative time compared to other procedures; 2) easy access to the duodenum and biliary tree endoscopically; 3) SASI does not divide the duodenum, thus eliminating the possibility of duodenal stump leakage, a serious complication with an incidence range between; 4) the tension on the anastomosis lower than other techniques; 5) there are no blind loops, excluded segments, or foreign bodies; 6) SASI is completely reversible . Single anastomosis sleeve jejunal (SASJ) bypass, which is the focus of this study, is a modification of SASI using a shorter biliopancreatic limb length compared to SASI to prevent long-term nutritional complications . The SASJ bypass appears to be safer than the SASI procedure in patients with excessive weight loss and nutritional deficiencies and is simpler due to its improved surgical ergonomics . Aim of the Work This study aims to evaluate the three-year outcomes of SASJ bypass as a primary bariatric procedure in a tertiary bariatric center for weight loss, comorbidity resolution, and both early and late complications.
