There are multiple results for the term "Coco surgery," but they are not related to a specific medical procedure. Here is a breakdown of the different results:

• COronary COllateral (COCO) technique: This is a surgical technique used to treat chronic internal carotid artery occlusion.

• Soft tissue fibrosarcoma surgery: A post on Instagram by Hannah Shaw mentions "Cocos second surgery for a soft tissue fibrosarcoma (a cancerous tumor)".

• Plastic surgery: There are multiple results related to Coco Austin, a model and actress, and her plastic surgery procedures.

• Leg surgery: A news article mentions that singer Coco Lee underwent leg surgery in February 2023 after hip displacement.

Therefore, "Coco surgery" is not a specific medical procedure, but rather a term that can refer to different types of surgeries depending on the context.
