For use by an assessor reviewing a sleeve gastrectomy video outside this website. No video is uploaded to or stored by SOSATS.
Structured review
Rate observable performance from 1 (substantial improvement needed) to 5 (consistently strong).
0/10
Global performance
Tissue exposure
Were the operative field, stomach, hiatus and greater curvature exposed clearly and safely?
Global performance
Efficiency of time and motion
Were movements purposeful, economical and free from unnecessary repetition?
Global performance
Flow of the operation
Did the procedure progress in a planned sequence with appropriate anticipation of each step?
SOSATS procedure domains
Fundal mobilisation
Was mobilisation complete enough to identify anatomy and avoid leaving retained fundus?
SOSATS procedure domains
Left crus and gastro-oesophageal junction
Was dissection to the left crus clear while respecting and avoiding injury to the gastro-oesophageal junction?
SOSATS procedure domains
Staple orientation
Was the stapler aligned to create an appropriate sleeve without narrowing at the incisura or twisting the tube?
SOSATS procedure domains
Staple firing
Were tissue thickness, compression, progressive firing and reload choice considered before each firing?
Curriculum review
Antral and incisura strategy
Was the first firing position and subsequent contour considered in relation to the pylorus and incisura?
Curriculum review
Staple-line and hiatus review
Was the staple line inspected for integrity, bleeding and geometry, with the hiatus reviewed where appropriate?
Curriculum review
Teamwork and crisis awareness
Did the video demonstrate clear communication, leadership, situational awareness and readiness to respond to difficulty?

Safety note: SOSATS was validated for simulated video-rated performance and is suitable for formative feedback. Further research is required before high-stakes use. Assessor ratings should be interpreted within supervised training governance.
