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: This study compared the safety and efficacy of sleeve gastrectomy (SG) and one anastomosis gastric bypass (OAGB) as conversion surgical procedures for patients who had adjustable gastric band (LAGB) and experienced suboptimal response or weight recurrence. The results showed that both procedures resulted in significant weight loss and similar remission of comorbidities, but OAGB had a higher complication rate compared to SG.

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: The study presented the long-term safety results of REALIZE adjustable gastric band in patients with morbid obesity, showing a reoperation rate of 8.9% due to serious adverse events at 5 years, with band slippage being the most common issue affecting 6.9% of the population. No new safety concerns were identified during the 5 years of follow-up, and although the predefined safety criteria were not met, the safety profile and long-term effectiveness observed in this study are consistent with those in the current literature.

Summary: The study evaluated complication rates following removal of Laparoscopic adjustable gastric banding (LAGB), including conversion to other bariatric procedures. The 30-day complication rate was 11.83%, with surgical site infections being the main complication, and a significantly higher complication rate for conversion to LSG.

Summary: This study aimed to investigate commonly used staple line reinforcement (SLR) techniques and their effects on morbidity and mortality in patients undergoing single-stage band conversion to sleeve surgery. The results showed that there were no statistically significant differences in rates of death, reoperation, readmission, reintervention, number of bleeding events, and staple line leaks across different SLR technique groups.

Summary: This study compared the safety of single- versus two-stage conversion of adjustable gastric band (AGB) to gastric bypass (RYGB) or sleeve gastrectomy (SG) procedures, and found that single-stage conversion was associated with lower morbidity. Conversion to SG appeared to be safer than RYGB.

Summary: The study demonstrates that revisional bariatric surgery can be safely conducted in the private sector with positive outcomes. One-stage conversions are feasible and do not adversely impact morbidity or weight loss outcomes. Importantly, success following revisional surgery is not dependent on the indication for revision or weight loss outcomes following primary surgery.

Summary: This study compared the outcomes of one-stage Roux-en-Y gastric bypass (RRYGB) and primary Roux-en-Y gastric bypass (PRYGB) after Laparoscopic adjustable gastric banding (LAGB). The results showed that one-stage RRYGB after LAGB is safe and effective, with comparable rates of complications, re-interventions, and resolution of associated comorbid conditions compared to PRYGB.

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: Following sleeve gastrectomy, esophago-gastric transit is primarily driven by isobaric pressurization of the stomach induced by repeated esophageal peristaltic contractions, with a strong association with reflux. Transit of food from the esophagus to the small bowel post-operatively is rapid and substantial.

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.
