Ultrasound against rectal nodules: goodbye to the scalpel

Published on April 28, 2026 | Translated from Spanish

A new clinical trial explores the use of focused ultrasound to treat endometriosis nodules in the rectum. The technique, which has already shown results in previous studies, applies high-intensity waves to destroy endometrial tissue without cuts or incisions. For those suffering from severe pain, bleeding, and fertility problems, this alternative to traditional surgery promises faster recovery and fewer digestive risks.

How destructive ultrasound works 🎯

The procedure uses a transducer that emits concentrated ultrasound waves at the endometriosis nodules in the rectum. These waves generate focused heat (between 60 and 90 degrees Celsius) that coagulates and destroys the abnormal cells without damaging surrounding healthy tissue. Unlike surgical resection, which requires removing part of the intestine and carries risks of infection or fistulas, this technique leaves no external scars and allows the patient to return to their routine in days, not weeks.

Ultrasound: from seeing fetuses to frying endometriosis 🤯

Who would have thought that the same technology used to check if the baby is breech would now be dedicated to frying intestinal nodules. It's as if the ultrasound machine had an identity crisis and decided to go over to the dark side of gynecology. Of course, patients probably prefer a controlled heat-up to having their colon sliced like a sausage. Good thing science advances, even if sometimes it seems like the clinic's equipment gets bored and looks for new hobbies.
