The world's first surgery was performed to transplant a mass called "organoid", which is a collection of various cells of the intestine made from the patient's own cells, into the intestine of a patient with the intractable disease "ulcerative colitis" designated by the government. A group from Tokyo Medical & Dental University made a presentation.
This was announced at a press conference on the 7th by a group of Professor Ryuichi Okamoto of Tokyo Medical & Dental University.
Ulcerative colitis is a disease in which the mucous membrane of the large intestine is inflamed and causes severe abdominal pain and diarrhea.
The group is called "organoid", which contains various cells in the intestinal epithelium such as stem cells that produce mucous membranes by removing healthy cells from the large intestine of one patient who has not been sufficiently effective with conventional treatment. I made a lot of lumps.
Then, he had an operation to transplant an organoid to the part of the patient who had an ulcer in the intestine.
The patient's progress is going well.
The group says that the transplanted organoids can be expected to regenerate the intestinal mucosa, and the safety and efficacy will be confirmed over the next year.
According to the group, it is the first surgery in the world to transplant organoids, and there are plans to perform surgery on seven more patients in the future.
Professor Okamoto said, "It took a very long time to study for 10 years, but it is a great achievement to have started with the first surgery this time."
