Summary: Laparoscopic adjustable gastric band (LAGB) is effective for most patients with long-term durability, but approximately one fifth of patients will require reoperation, with inadequate weight loss accounting for only one fifth of these cases, and band slippage/prolapse being the most common non weight-related indication for reoperation.

Summary: Revisional LOAGB surgery is effective and safe for patients with weight loss failure after LSG. Patients with insufficient weight loss and persistent fundus anatomy tend to lose more weight compared to patients with weight regain and diffuse stomach dilation.

Summary: This study found that LAGB surgery, which constricts the stomach, can indirectly alter brain activation in response to food cues, potentially leading to changes in food craving and preference that support sustained weight loss after surgery.

Summary: MGB/OAGB is a recent low-risk bariatric surgical procedure commonly used in the treatment of severe obesity. Diagnostic imaging plays a significant role in evaluating treatment outcomes and detecting potential complications in the postoperative period.

Summary: The study demonstrates that single-stage LRYGB and LSG as revisional surgery after failed gastric banding are safe with an acceptable complication rate and low mortality in the 30-day observation, but conversion to LRYGB increases the risk of perioperative complications.

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 aimed to compare the weight loss, obesity-related comorbidities, and biochemical outcomes of LSG versus LRYGB through a meta-analysis of RCTs. The results showed that LRYGB resulted in greater reductions in body mass index and improved dyslipidemia compared to LSG at 1 and 3 years, but the data beyond 3 years is insufficient for drawing conclusions.

Summary: This study compared outcomes of patients undergoing primary and revisional robotically assisted laparoscopic Roux-en-Y gastric bypass. The revisional group had longer operative times, slightly higher early complication rates, increased readmissions for oral intolerance, and higher rates of gastrojejunal stricture compared to the primary group. However, there were no significant differences in overall complication rates between the two groups.

Summary: The most common indication for revisional surgery after sleeve gastrectomy is weight loss failure. Options for revisional surgery include RYGB, OAGB, and re-sleeve, but there are higher complication rates following revisional surgery. The efficacy of re-operation in terms of weight loss and morbidity reduction is still debated due to the lack of high-quality evidence in the field.

Summary: This study compared the perioperative, early postoperative, and 1-year postoperative outcomes of adolescents with obesity who underwent laparoscopic sleeve gastrectomy (LSG) or one anastomosis gastric bypass (OAGB). The results showed that there were no significant differences in perioperative complications and postoperative complications between the two surgeries. However, OAGB was associated with significantly fewer gastrointestinal symptoms compared to LSG.

Summary: This study comprehensively evaluated the long-term outcomes of laparoscopic sleeve gastrectomy (LSG) as a revisional procedure after laparoscopic adjustable gastric banding (LAGB) and identified predictors of outcomes. The results showed that revision LSG provided long-term weight loss, but had significantly more complications and higher re-operation rates compared to primary LSG. Predictors of worse outcomes included eroded band, multiple prior bands, severe esophageal dysmotility, and elevated baseline weight.

Summary: Liver biopsy remains the gold standard for characterizing and evaluating treatment response in nonalcoholic fatty liver disease (NAFLD), but there is variability in individual components such as fibrosis stage between different biopsy sites. Clinicians should consider biopsies from varied sites to better assess liver disease severity, as a combination of biopsy techniques improves the detection of pathology.

Summary: This study evaluated perioperative mortality risk prediction tools relevant to an Australian context and identified four potential tools for adaptation, including SMPM, POSPOM, SORT, and NZRISK. SORT and NZRISK may provide an opportunity to simultaneously investigate and develop a locally valid perioperative mortality risk prediction model with high predictive performance.

Summary: This study achieved international consensus on criteria for hospital discharge after esophagectomy through a 3-round Delphi process involving 40 esophageal surgeons from 16 countries and 4 continents. The consensus included criteria related to nutrition, gas passage, removal of central venous catheters, and use of adequate analgesia. These standardized endpoints can serve as objective measures for short-term recovery and assist in making decisions about patient discharge to reduce the risk of premature discharge or prolonged admission.

Summary: The study evaluated the mechanisms associated with reflux events after sleeve gastrectomy (SG). The results showed a strong association between reflux and SG, and identified three unique categories of reflux. The study also found that elevated gastro-esophageal pressure gradient was the main mechanism of reflux.

Summary: Low skeletal muscle index (SMI) is associated with an increased risk of post-operative pneumonia and longer length of stay (LOS) for patients with complications, but not with 5-year overall or disease-free survival after oesophago-gastric cancer surgery. Assessment of muscle mass may require additional measures to enhance preoperative risk assessment.

Summary: This study aimed to define the expected average length of stay (ALOS) of bariatric surgery in Australia and to identify factors that influence ALOS. The study found that increased patient age, diabetes, rural living, procedural complications, and surgeon and hospital case volume all contributed to a small increase in ALOS following bariatric surgery.

Summary: This study evaluated the NASA Task Load Index (TLX) as an objective measure of technical difficulty of an operation. The results showed that the NASA TLX score correlated significantly with operative duration, blood loss, previous abdominal surgery, and the surgeon's assessment of difficulty. This tool could be used in research and teaching settings to assess surgical difficulty and monitor a trainee's proficiency over time.
