Abstract:Objective To evaluate the feasibility of single-use digital hysteroscope based on enhanced recovery after surgery concept in day surgery.Methods A retrospective analysis was conducted on 295 patients who underwent treatment with single-use digital hysteroscope from February 2023 to April 2024. The study analyzed operation time, success rate, surgical complications, recurrence rate of diseases, and patient satisfaction.Results The average operation time with single-use digital hysteroscope for treating endometrial polyps: 1 polyp was (4.973 ± 0.384) min, 2 polyps was (6.193 ± 0.533) min, 3 ~ 5 polyps was (10.279 ± 0.847) min, and >5 polyps was (15.938 ± 2.008) min. The average operation time for treating endometrial hyperplasia was (4.323 ± 0.954) min, retained products of conception was (8.077 ± 1.317) min, submucosal uterine myoma was (16.750 ± 1.541) min, intrauterine adhesion was (11.611 ± 2.598) min, endometritis was (3.500 ± 0.463) min, septate uterus and uterine cavity without obvious abnormalities was (2.214 ± 0.636) min and closed tubal ostium was (14.167 ± 2.255) min, and residual intrauterine device was 3.5 min. The success rate of all cases was 100.0%, the surgical success rate was 98.3%, the patient satisfaction rate was 99.3%, and 3 cases of the complication (2 cases in induced abortion syndrome, 1 case in postoperative fever, and no serious adverse events occurred). After six-month follow-up, 8 patients were lost to follow-up, and 5 patients had disease recurrence ( 3 cases in endometrial polyps, 2 cases in mild intrauterine adhesion).Conclusion Single-use digital hysteroscope can treat common intracavitary diseases of gynecology, with short operation time, high success rate, good patient satisfaction, minor complications, and favorable conditions for rapid postoperative recovery. It can be used for day surgery. It is worthy in clinical application.
