Brief summary (from the registry)
This study looks at two types of injections (called PECS and ESP blocks) to see which one works better for reducing pain after breast cancer surgery (mastectomy). The main question it asks is: Which block is better at reducing pain after surgery - PECS or ESP? Women who had this surgery and received one of the two blocks were followed for three months. We looked at how much pain they felt, how much pain medication they needed, and whether they still had pain months later. The results showed that both blocks helped with pain right after surgery. The ESP block lasted a little longer at first, but in general, both groups needed about the same amount of pain medicine. Three months later, about half of the patients still had some pain - especially those who had more extensive surgery or had nerve pain early on. There was no big difference between the two blocks when it came to long-term pain.
