A retrospective cohort study involving 198 adults undergoing laparoscopic cholecystectomy for benign gallbladder disease evaluated indocyanine green (ICG) fluorescence imaging as an adjunct to conventional white-light laparoscopy.
Complete intraoperative visualization of the cystic duct, common bile duct, common hepatic duct, and cystic duct–CBD junction was achieved substantially more often with ICG fluorescence guidance—91.3% versus 56.8% with conventional visualization.
ICG-guided procedures also demonstrated improved operative efficiency. Median time to obtaining the critical view of safety (CVS) decreased from 21 minutes to 12 minutes, while median total operative time decreased from 48 minutes to 36 minutes. Fewer patients in the fluorescence group required postoperative drains.
No bile duct injury, postoperative bile leak, conversion, reoperation, or ICG-related adverse event was reported.
Surgical Relevance
Near-infrared fluorescence cholangiography can provide real-time visualization of biliary anatomy without requiring duct cannulation or ionizing radiation. This may be particularly useful during anatomical orientation, surgical training, and cases in which conventional white-light identification of biliary structures is challenging.
However, fluorescence should never replace meticulous dissection or the critical view of safety. The study was non-randomized because patients selected their operative approach after counselling; therefore, it supports improved anatomical visualization and workflow efficiency but does not establish that ICG reduces bile duct injury.
Clinical Takeaway: ICG fluorescence is a valuable adjunct for identifying biliary anatomy and may accelerate achievement of CVS, but safe cholecystectomy still depends on anatomical certainty, disciplined dissection, and appropriate bailout strategies when CVS cannot be obtained.

Bariatric Surgery Associated With Lower Long-Term Dementia Risk in Obesity and Type 2 Diabetes
A nationwide propensity score-matched registry study evaluated the long-term incidence of dementia among patients with obesity and type 2 diabetes who underwent metabolic and bariatric surgery compared with matched nonsurgical controls.
Over approximately nine years of mean follow-up, bariatric surgery was associated with a lower long-term incidence of dementia. The 15-year cumulative incidence was 1.8% following surgery compared with 2.7% among nonsurgical controls, corresponding to a reported subdistribution hazard ratio of 0.60.
The association extended to both Alzheimer disease and vascular dementia, suggesting that the long-term consequences of metabolic surgery may extend beyond conventional weight, glycemic and cardiovascular outcomes.
An important contrasting signal was a higher occurrence of alcohol-related dementia after surgery, although absolute event rates were low.
Surgical Relevance
Bariatric surgery counselling increasingly encompasses more than weight reduction. Long-term benefits may involve diabetes control, cardiovascular risk, renal outcomes, mobility, quality of life and potentially cognitive health.
At the same time, postoperative behavioral and nutritional surveillance remains essential. Alcohol-use patterns can change following some bariatric procedures, reinforcing the importance of long-term screening and counselling.
Clinical Takeaway: Metabolic surgery may be associated with a meaningful reduction in long-term dementia risk among patients with obesity and type 2 diabetes, but lifelong metabolic, nutritional, psychological and alcohol-related surveillance remains essential.

Evidence for Prehabilitation Before Metabolic and Bariatric Surgery Remains Fragmented
A bibliometric review mapped the available scientific literature addressing prehabilitation before metabolic and bariatric surgery. Despite widespread clinical interest, only 35 studies met inclusion criteria across eight databases and grey literature sources.
Research activity has increased substantially since 2020 but remains geographically concentrated, particularly in North America. Investigators identified limited international collaboration, heterogeneous study designs, and substantial variation in how prehabilitation programs and outcomes are defined.
Prehabilitation may include combinations of preoperative weight reduction, exercise training, respiratory conditioning, nutritional optimization, psychological preparation, smoking cessation and metabolic optimization.
However, the review demonstrates that widespread clinical enthusiasm has developed faster than a standardized evidence base.
Surgical Relevance
Bariatric programs should avoid defining prehabilitation success solely through short-term weight loss or isolated exercise measurements. More clinically meaningful endpoints include:
- Anesthetic readiness
- Functional capacity
- Postoperative pulmonary complications
- Overall morbidity
- Length of hospitalization
- Early mobilization
- Readmission
- Nutritional status
- Long-term behavioral adherence
Programs implementing prehabilitation should ideally measure these outcomes systematically so that local practice contributes to evidence-based pathway refinement.
Clinical Takeaway: Prehabilitation is biologically and clinically attractive before bariatric surgery, but standardized protocols and meaningful surgical outcome measures are still needed to determine which interventions provide the greatest benefit.

AI-Assisted Upper GI Endoscopy Improves Detection of Esophageal and Gastric Neoplasia
A systematic review and meta-analysis of 10 randomized controlled trials involving 87,721 participants evaluated real-time artificial intelligence assistance during esophagogastroduodenoscopy (EGD).
AI-assisted endoscopy significantly increased neoplasm detection in both the esophagus and stomach, with pooled risk ratios of approximately 1.47 for each anatomical site.
Computer-assisted detection increased the number of esophageal neoplastic lesions identified per examination. AI-supported EGD also improved detection of gastric cancer and low-grade intraepithelial neoplasia.
These findings provide increasingly strong evidence that AI may function as a clinically meaningful second observer during diagnostic upper gastrointestinal endoscopy.
Surgical Relevance
Improved endoscopic detection has direct consequences for minimally invasive upper-GI surgery. Identification of additional or earlier lesions can influence endoscopic resection eligibility, ESD planning, LECS selection, surgical margins, extent of gastric or esophageal resection, lymph-node strategy, and multidisciplinary treatment sequencing.
However, AI should remain an adjunct rather than a substitute for high-quality systematic examination and expert endoscopic judgment.
Clinical Takeaway: Randomized evidence increasingly supports real-time AI assistance for improving upper-GI neoplasia detection, potentially strengthening the diagnostic pathway preceding endoscopic and surgical cancer treatment.

Endoscopy-Related Musculoskeletal Injury Is Common and Represents an Important Surgeon-Safety Issue
A national survey involving 81 credentialled Australian endoscopists, most of whom were surgeons, examined occupational musculoskeletal disorders related to endoscopic practice.
Approximately 61.7% reported either current or previous endoscopy-related musculoskeletal injury. The most frequently affected anatomical regions were the thumbs and hands, lumbar spine, and cervical spine.
Higher weekly colonoscopy volume was significantly associated with injury. Symptoms frequently worsened during or following procedures, and more than half of affected clinicians reported requiring formal treatment or experiencing an impact on activities outside work.
Surgical Relevance
Endoscopic and laparoscopic surgeons share many occupational ergonomic hazards: sustained static posture, repetitive hand movements, grip force, instrument torque, inappropriate monitor height, awkward neck rotation and prolonged procedural volume.
Surgeon ergonomics should therefore be regarded as an occupational safety issue rather than simply a comfort preference. Practical measures include optimizing monitor position and table height, minimizing unnecessary wrist deviation and grip force, incorporating microbreaks, rotating high-volume workloads where feasible, and obtaining early assessment of persistent hand, neck, shoulder or back symptoms.
Training programs should also teach ergonomics alongside technical skill, allowing trainees to develop sustainable operating habits before poor posture becomes ingrained.
Clinical Takeaway: Musculoskeletal injury is common among high-volume endoscopists. Ergonomic training, appropriate equipment setup, workload management, microbreaks and early treatment are important for maintaining surgeon health and career longevity.

Key Message
The 23 August 2026 evidence update demonstrates that improving minimally invasive surgery increasingly requires attention to both sides of the operating table. ICG fluorescence and AI-assisted endoscopy can enhance anatomical and pathological recognition; metabolic surgery may provide benefits extending into long-term cognitive health; bariatric prehabilitation requires stronger standardized evidence; and surgeon ergonomics deserves recognition as an important component of procedural safety.
The future of minimally invasive surgery depends not only on smaller incisions, but on better visualization, earlier disease detection, optimized patients, healthier surgeons, and intelligent technology used alongside—not instead of—sound surgical judgment.
