Gynecological surgery using the Kangduo robotic system

Robotic surgery represents a notable advancement in the field of minimally invasive gynecological surgery. Although the Kangduo Robot® SR1000 (KD-SR-01) surgical system has shown improved stability and high efficiency, studies describing its use for gynecological surgery are limited. We aimed to review the safety and effectiveness of the KD-SR-01 system in gynecologic surgery and compare it with conventional laparoscopic operation. We compared patient characteristics and short-term outcomes in cases of gynecological surgery conducted using the KD-SR-01 system and laparoscopic minimally invasive procedures between March 2024 and October 2024. The short-term clinical efficacies of both surgical modalities were compared by performing statistical analyses. The KD-SR-01 system was used for total hysterectomy due to benign uterine tumors in 144 cases, ovarian cyst removal surgery due to benign ovarian tumors in 25 cases, unilateral adnexectomy due to benign ovarian tumors or borderline tumors in 25 cases, staging of early endometrial cancer in 24 cases, and radical cervical cancer resection for early cervical cancer in 24 cases. None of the patients showed serious complications (Clavien-Dindo grade ≥ 3). In comparison with traditional laparoscopic surgery, Kangduo robotic surgery resulted in a lower duration of hospitalization, operation time, blood loss, and drainage volume, but the two surgical modalities showed no differences in the complication rate. The Kangduo robotic system was safe and feasible for gynecological surgery. Evidence from additional studies and more surgical experience are required to determine the long-term outcomes and indications for gynecological surgery using this robotic system.

Analysis of Distributions of HPV Infection in Females with Cervical Lesions in the Western District of Beijing Chaoyang Hospital

Objective. To analyze the distribution of human papilloma virus (HPV) infection in women with cervical lesions of different grades and analyze the relationship of high-risk HPV and cervical lesions in order to facilitate targeted prevention. Methods. The infection status of HPV subtype was statistically analyzed in patients who underwent colposcopy examination from April 2017 to June 2019. Results. The infection rate of HPV was 81.4% in chronic cervicitis, 82.9% in 1ow-grade squamous intraepithelial lesion (LSIL), 63.7% in HSIL (high-grade squamous intraepithelial lesion), and 50% in cervical squamous cell carcinoma (CSCC). Among the 16 high-risk HPV types, the top six HPV types with the comprehensive infection rates were HPV16 > HPV52 > HPV58 > HPV18 > HPV51 > HPV53 in turn, and the infection rates were 23.3%, 14.8%, 13.3%, 9.8%, 9.2%, and 8.8%, respectively. The infection rates of HPV16 in chronic cervicitis group, LSIL group, and HSIL group were significantly different. There was no significant difference in the injection rates of HPV52, HPV58, and HPV18 among the three groups. HPV infection rates were highest in the 31–40 years old group, followed by the 41–50 years old group. Conclusion. The distribution of different types of HPV varies in different tissue types, which can be used to develop relevant vaccines to achieve better prevention and treatment of cervical cancer.
