September 2, 2014A German company that makes power morcellation devices threatened legal action against a Boston physician lobbying for changes in the way doctors use the device. Karl Storz, which manufacturers Rotocut and other brands of morcellators, sent a letter to Dr. Hooman Noorchashm – whose wife suffered from uterine cancer after undergoing morcellation – claiming his campaign against the company’s fibroid-removal devices defames the manufacturer. The letter said Noorchashm sent several emails to Karl Storz CEO Dr. h.c. mult. Sybill Storz. The company claimed Noorchashm's emails stated that the device was the cause of death for some women and that he should stop his campaign immediately. “We will no longer tolerate unfounded and unproven allegations such as the ones contained in your previous emails and we will hold you responsible,” wrote Helmut Wehrstein, a member of Karl Storz’s Global Executive Committee. “Should we get to know further public statements from you that our device and/or management would be responsible for your wife’s or any other women’s uterine cancer, and/or any aggravation of their cancerous situation, we would not hesitate to take appropriate legal actions to protect our good name and our rights.” Noorchashm responded in kind, undeterred. "A Storz morcellator is used by a gynecological surgeon in Boston and causes my wife’s cancer to be spread inside her abdominal cavity, the company knows that this potentially deadly complication could occur, yet it continues to sell the product worldwide," he told the Cancer Letter, an online publication that focuses on cancer information. Morcellators are minimally invasive surgical instruments commonly used in uterine surgery. They are inserted through a small abdominal incision and can pulverize large pieces of tissue for easy removal. Doctors perform about 60,000 surgeries using power morcellators annually. Some studies show that the devices can uncover previously undetected cancer cells and spread them throughout the abdominal area. According to the U.S. Food and Drug Administration (FDA), 1 in 350 women are at risk for developing cancer after a morcellation procedure. Morcellation manufacturers, including Karl Storz and pharmaceutical giant Johnson & Johnson, face a growing number of lawsuits filed by women who suffered advanced cancers after the morcellation procedures.
