Dr. Masahide Kanayama is a world-renowned endometriosis surgeon whose work has transformed the lives of countless women suffering from severe pelvic pain, infertility, and complex gynecological conditions. His surgical techniques and unmatched expertise have allowed patients — many of whom had lost hope after years of misdiagnosis and ineffective treatments — to finally regain their health and their futures.

Dr. Kanayama is one of the few surgeons in the world capable of properly treating deep infiltrating endometriosis and adenomyosis. Through his development of deep haptic excision, he introduced a precise and effective method that fully removes disease that many surgeons cannot safely treat. Patients have traveled from across the United States and around the world to seek his care because his work provides results that are rarely available elsewhere.

Today, the United States has lost access to one of the few surgeons capable of performing this life-changing care. Patients who relied on Dr. Kanayama are now left searching for help that simply doesn’t exist in many places. For women living with severe endometriosis, this loss is not just inconvenient — it is devastating.

This petition calls for Dr. Kanayama to be allowed to return to the United States so that he can continue providing the lifesaving and life-changing medical care that so many patients urgently need. Women deserve access to the highest level of specialized treatment, and the medical community should not lose a surgeon whose work has helped restore health, dignity, and hope to so many.

By signing this petition, you are standing with patients who depend on Dr. Kanayama’s expertise and advocating for critical medical care that changes lives every day.

UPDATE: 

Since this petition was created, more patients from across the country have continued sharing their stories about how Dr. Kanayama changed their lives after years of pain, failed treatments, and being dismissed by other providers. Many patients are now struggling to find surgeons with the same level of expertise in treating deep infiltrating endometriosis and adenomyosis, highlighting just how rare and essential his care truly is.

The overwhelming support this petition has received reflects a much larger issue: women with complex endometriosis already face limited access to qualified specialists, long wait times, and delayed diagnoses. The loss of a surgeon with Dr. Kanayama’s skill and experience has left many patients feeling hopeless and without options.

We continue to stand with the countless women and families advocating for access to specialized, life-changing medical care. Every signature helps bring more awareness to the urgent need for experienced endometriosis specialists and the patients whose lives depend on them.

Please sign this petition to bring Dr.Kanayama back to America!
