Background: Laparoscopic sleeve gastrectomy (LSG) became the most frequent bariatric procedure performed in France (2011) and in the United States (2013), but studies reporting long-term results are still rare.
Setting: Private hospital, France.
Methods: This is a retrospective analysis of a prospective cohort of 168 patients who underwent LSG between 2005 and 2008. The objective of this study was to present the 8-year outcome concerning weight loss, modification of co-morbidities, and to report the revisional surgery after sleeve.
Results: The preoperative mean body mass index was 42.8 kg/m2 (31.1-77.9), 35 patients were super obese, and 64 patients had a previous gastric band. For LSG as a definitive bariatric procedure, 8 years of follow-up data were available for 116 patients (follow-up: 69%). Of the remainder, 23 patients underwent revisional surgery and 29 were lost to follow-up. For the entire cohort, the mean excess weight loss (EWL) was 76% (0-149) at 5 years and 67% (4-135) at 8 years, respectively. Of the 116 patients with 8 years of follow-up, 82 patients had>50% EWL at 8 years (70.7%). Percentages of co-morbidities resolved were hypertension, 59.4%; type 2 diabetes, 43.4%; and obstructive sleep apnea, 72.4%. Twenty-three patients had revisional surgery for weight regain (n = 14) or for severe reflux (n = 9) at a mean period of 50 months (9-96). Twelve patients underwent resleeve gastrectomy, 6 patients underwent conversion to a bypass, and 5 patients to duodenal switch (1 single anastomosis duodeno-ileostomy). A total of 31% of patients reported gastroesophageal reflux symptoms at 8 years.
Conclusions: At 8 years postoperatively, the LSG as a definitive bariatric procedure remained effective for 59% of cases. The results appear to be more favorable especially for the non-super-obese patients and primary procedures. LSG is a well-tolerated bariatric procedure with low long-term complication rates.

Background: Addressing language barriers through accurate interpretation is crucial for providing quality care and establishing trust. While the ability of artificial intelligence (AI) to translate medical documentation has been studied, its role for patient-provider communication is less explored. This review evaluates AI's effectiveness in clinical translation by assessing accuracy, usability, satisfaction, and feedback on its use.

The rising prevalence of obesity has led to an increase in bariatric procedures, with laparoscopic Roux-en-Y gastric bypass (LRYGB) being one of the most commonly performed surgeries due to its efficacy and safety. However, internal hernia (IH) remains a significant complication post-LRYGB. The debate over preventive closure of mesenteric defects (MD) during LRYGB continues, with no consensus on the optimal technique.

Introduction: Strategies to address suboptimal weight loss after Roux-en-Y gastric bypass (RYGB) can be developed if at-risk patients are identified in advance. This study aimed to build a pre-surgery prediction nomogram for early prediction of insufficient weight loss (IWL) or weight regain (WR) after bariatric surgery in Chinese patients.
Methods: In this retrospective study, 187 patients with obesity and type 2 diabetes who underwent laparoscopic RYGB were followed yearly for 3 years.

Background: Although bariatric and metabolic surgical methods, including duodenal-jejunal bypass (DJB), were shown to improve metabolic dysfunction-associated steatotic liver disease (MASLD) in clinical trials and experimental rodent models, their underlying mechanisms remain unclear. The present study therefore evaluated the therapeutic effects and mechanisms of action of DJB in rats with MASLD.
Methods: Rats with MASLD were randomly assigned to undergo DJB or sham surgery.
