ABSTRACT Prolonged operative time is associated with increased surgical complications, resource utilization, and cost. While factors such as surgeon experience and patient habitus are well recognized, the impact of anatomical anomalies and variations remains poorly quantified. This systematic review evaluates the influence of abdominal structural anomalies and anatomical variations on operative time. Following PRISMA 2020 guidelines, a search of PubMed (2000–2025) identified 82 eligible studies. Operative‐time impact was assessed using added operative time relative to reference benchmarks. The unit of analysis was the procedure‐level observation. Observations were stratified by procedure category and surgical complexity and summarized using median added operative time and range. Among procedure‐level observations with available benchmarks, 13 of 14 (92.9%) structural anomalies, 48 of 54 (88.9%) situs inversus cases, and 10 of 11 (90.9%) other anatomical variants demonstrated increased operative time relative to baseline. Structural anomalies were associated with larger median increases, particularly in colorectal procedures, whereas anatomical variations demonstrated a more heterogeneous effect across procedural systems. Higher‐complexity procedures, including pancreatic operations, showed greater absolute increases in operative time. Preoperative identification of anatomical differences was associated with attenuation of operative delays. Structural anomalies are frequently associated with increased operative duration, whereas anatomical variations demonstrate a more variable and context‐dependent effect. The magnitude of operative time impact is influenced by procedural complexity and preoperative planning. Incorporating anatomical variability into surgical planning may reduce avoidable operative delays and improve operative efficiency.

ABSTRACT Photogrammetry has emerged as a powerful tool in medical education, offering precise and cost‐effective 3D anatomical models that enhance spatial learning and accessibility. This systematic review synthesizes evidence from forty‐eight (48) peer‐reviewed studies (2000–2025) to evaluate photogrammetry's applications, technical workflows, and educational outcomes in anatomy and surgical training. Findings demonstrate its effectiveness across training levels, with high learner satisfaction (e.g., 96.4% preference over traditional methods) and sub‐millimeter accuracy in rendering complex structures like neuroanatomy and musculoskeletal systems. Photogrammetry's adaptability for remote learning and specimen preservation addresses critical gaps in resource‐limited settings. However, challenges persist, including the lack of tactile feedback and difficulties in visualizing deep anatomical relationships. Future directions should focus on integrating artificial intelligence (AI)‐assisted processing, hybrid digital–physical models, and immersive technologies like virtual reality (VR)/augmented reality (AR) to bridge these gaps. By balancing innovation with evidence‐based implementation, photogrammetry can further solidify its role as a transformative adjunct in modern medical curricula.
