Summary: This study evaluated the phase angle (PhA) and sarcopenia in young individuals pre- and post-Roux-en-Y gastric bypass surgery. The results showed that the postoperative group had significantly lower PhA and higher resistance (R). Handgrip strength and gait speed were negatively correlated with R, hs-CRP, and leptin. Appendicular lean mass was negatively correlated with reactance and R. Overall, PhA and other components of bioelectrical impedance analysis were found to be correlated with sarcopenia.

Summary: Background: The rates of secondary bariatric surgery have increased, with sleeve gastrectomy to gastric bypass conversion being the most common. This study evaluates the outcomes of this conversion compared to primary Roux-en-Y gastric bypass (RYGB) surgery using MBSAQIP data. Methods: The study analyzed the data of patients who underwent sleeve gastrectomy to RYGB conversion and primary laparoscopic RYGB, matching them based on preoperative characteristics. Results: The analysis showed that the conversion from sleeve gastrectomy to RYGB was associated with higher readmissions, interventions, conversion to open surgery, longer hospital stay, and longer operative time compared to primary RYGB. However, there were no significant differences in mortality or rates of bariatric complications. Conclusion: The study concludes that conversion from sleeve gastrectomy to RYGB is a safe and feasible procedure with reasonable outcomes compared to primary RYGB.

Summary: The study evaluated the long-term efficacy of Roux-en-Y Gastric Bypass (RYGB) surgery by assessing weight loss and comorbidity improvement in patients 10 years or more after the surgery. Results showed a significant decrease in body mass index (BMI) and successful comorbidity remission. Although a small proportion of patients required revision surgery for weight loss failure, RYGB was confirmed as an effective primary bariatric intervention.

Summary: This study examined the relationship between changes in resting metabolic rate (RMR) after Roux-en-Y gastric bypass (RYGB) surgery and weight loss on long-term follow-up. The results showed that RMR was significantly lower at 6 months post-surgery compared to pre-surgery levels, but returned to similar values at 36 months. There was a positive correlation between RMR and percentage of fat-free mass, and a negative correlation with body weight, body mass index, and percentage of fat mass. The increase in RMR/kg after RYGB was found to be a major factor associated with satisfactory weight loss on long-term follow-up.

Summary: Marginal ulcers (MU) are a potential complication following Roux-en-Y gastric bypass (RYGB) surgery, with an average prevalence of 4.6%. Early identification and prompt intervention are crucial to prevent further complications. MU is a complex condition influenced by factors such as smoking, Helicobacter pylori infection, NSAID use, and pouch size. Diagnosis is typically made through endoscopy, and treatment involves modifying risk factors and medical therapy with proton pump inhibitors. Surgical intervention may be necessary for complicated ulcers, while endoscopic procedures and vagotomy may be considered for recurrent or challenging cases.

Summary: The prevalence of obesity has been increasing rapidly in recent decades, making it one of the most impacting diseases on global health. It is a chronic disease associated with various comorbidities that result in a reduced life expectancy and quality of life. The treatment of obesity requires a multidisciplinary approach by a specialized medical team and can be done through conservative or surgical treatments. Vertical gastrectomy, mixed techniques, and gastric bypass are the most commonly used surgical techniques. The choice of technique should consider the characteristics of each patient and the surgical team's experience.

Summary: Morbid obesity is a chronic disease with a rising incidence, and surgical treatment has shown superior outcomes compared to conventional weight loss measures. This study evaluated the long-term weight loss outcomes, comorbidity reduction, and adverse effects of Roux-en-Y Gastric Bypass (RYGB), Biliopancreatic Diversion (BPD), and Sleeve Gastrectomy (SG) at 10 years. RYGB and BPD resulted in significant weight loss, with no observed differences in diabetes resolution and adverse outcomes. Longer follow-up reports are important for comparing the outcomes of different bariatric operations.

Summary: A survey study found that digestive surgeons have limited knowledge and varied practices in nutritional support for gastrointestinal cancer patients. Most participants correctly defined malnutrition and understood the advantages of enteral infusion and peripheral parenteral nutrition. However, there were discrepancies in the diagnosis of malnutrition and the indication for preoperative nutritional support. Standardized clinical protocols and a national consensus on nutrition support are needed.

Summary: This study compared the economic cost of laparoscopic Roux-en-Y gastric bypass surgery following an Enhanced Recovery After Surgery (ERAS) protocol with a standard-of-care protocol. The results showed that patients following the ERAS protocol had significantly lower postoperative pain, nausea or vomiting, and hospital stay. In terms of economics, the pharmacological expenditures, costs of complementary tests during the hospital stay, and costs related to the hospital stay were significantly lower in the ERAS group, resulting in a mean saving of $1458.62 per patient in the total cost of the procedure.

Summary: Liver metastases of colorectal carcinoma (LMCC) with macroscopic intrabiliary ductal involvement can clinically and radiologically mimic a cholangiocarcinoma. However, a thorough anatomopathologic and immunohistochemical study is required to differentiate due to the distinctive clinical features and relatively indolent biological behavior of LMCC, which reflect a better prognosis and long-term survival. We present a case of LMCC with intrahepatic biliary ductal involvement, diagnosed definitively through immunohistochemical analysis showing a characteristic CK7 - /CK20 + pattern.
