Surgical approach
The right patient comes before the right operation.
Dr Afilitak’s assessment is not based on BMI alone. Related conditions, reflux, previous operations, nutritional risk, expectations and the ability to maintain long-term follow-up are considered together. His clinical scope includes primary procedures, revisional surgery and bariatric complication management.
Bariatric surgery is not simply about reducing stomach volume. Successful obesity treatment requires appropriate patient selection, safe surgical technique and structured long-term follow-up.
The clinical approach, illustrated
One care language from consultation to post-operative review.
