Transrectal light-guided probe assisted laparoscopic resection of deep infiltrating endometriosis: A case report

In the surgical treatment of deep infiltrating endometriosis, the completeness of lesion removal is crucial for the success of the procedure. Consequently, an array of auxiliary surgical methods are continuously being refined to improve the precision of lesion excision and minimize the incidence of complications. Among these, the traditional rectal probe aids in bowel mobilization and evaluates tissue suppleness, but lacks clear visualization of the intestinal wall thickness. To optimize lesion exposure, reduce complications, and remove lesions as completely as possible, we have enhanced this tool. This paper reports the pioneering use of a transrectal light-guided probe, invented by our medical team, in the surgical treatment of a patient with deep infiltrating endometriosis. The patient, a 26-year-old female with a seven-year history of dysmenorrhea, was initially suspected of having ovarian chocolate cysts, strongly suggesting the presence of deep endometriosis. Having ruled out surgical contraindications and completed all preoperative preparations, a laparoscopic excision of endometriotic lesions with the aid of a transrectal light-guided probe was carried out. One year post-treatment, the patient reported substantial alleviation of dysmenorrhea, the complete resolution of dyspareunia, and no long-term complications were noted. The innovation and implementation of this auxiliary surgical technique in clinical settings have demonstrated the potential to reduce surgical complications, thereby significantly improving the quality of life and long-term prognosis for patients with deep endometriosis.
