Endometriosis Surgery Without Post-Op Hormones: Recurrence Within 5 Years

#397 ‒ Endometriosis and adenomyosis: diagnosis, fertility,… · Jun 22, 2026 Health & Fitness

Without post-surgical hormonal suppression, endometriosis recurs at roughly 10% per year. A Mirena IUD inserted after surgery cuts that recurrence risk by 88% compared to placebo. Surgery alone is a temporary measure; the disease is chronic and demands a lifetime treatment plan.

Clinical case example #1: Managing endometriosis in a young woman seeking pain relief while preserving future fertility

At 52:20 · chapter starts 45:52

The first case study grounds the episode's treatment principles in a real clinical scenario. A 20-year-old in pain who wants to preserve fertility but not conceive now faces a structured set of questions: Does she want children? How many? What is her ovarian reserve? What is the disease phenotype — importantly, does she have an endometrioma? How severe is her pain? Tomioka explains the logic for each option. Mirena IUD is excellent for five years of progesterone-mediated suppression but does not suppress ovulation, so it cannot control endometriomas, and it is contraindicated if myofascial pain (pelvic floor muscle tension) is present. Combined oral contraceptives are the most common first line, with a preference for the lowest effective estrogen dose to avoid stimulating lesions. Progestin-only pills (norethindrone, dienogest, desogestrel) are an alternative. If she fails to respond at 3 to 6 months, the medication changes or surgery is considered. Surgery is not first-line because it is very likely she will recur within 5 years unless a hormonal agent is used post-operatively — and a Mirena IUD placed after surgery cuts recurrence by 88% vs. placebo. The overarching frame is that endometriosis must be treated as a chronic disease requiring a life-plan, not a single intervention.

AI nailed Andrew Huberman's vertigo-vs-low-blood-pressure diagnosis because that pattern has been reported millions of times. But every patient's liver is different and data on liver surgeries is scarce worldwide — making solo robot surgery dangerous. The rule is simple: data abundance means AI can help; data scarcity means keep the human in the loop.
