The Department of Obstetrics and Gynecology at Zhongshan Hospital was established in June 1959, founded by predecessors including Zhou Yufen, Chen Junkang, Cai Hanrong, and Xu Xinglin, appointed by the former Shanghai Medical University. Over the past 60 years since its establishment, renowned obstetrics and gynecology specialists such as Sheng Danjing, Yang Laichun, Yang Dan, and Tu Ruiqin, as well as gynecological oncology expert Zang Rongyu, have successively worked in the department and served as its directors. The current director of the department is Chief Physician Zhang Jiarong. Currently, the department has a total of 23 physicians, including 2 chief physicians and 3 deputy chief physicians. The department has over 50 beds, with an annual outpatient volume of more than 70,000 patient visits, with patients coming from multiple provinces and cities across the country. In addition to senior specialist outpatient services (including special needs outpatient services), specialist outpatient services, and general outpatient services, the department also offers specialized outpatient services such as cervical screening and treatment clinics, endometriosis and endocrine clinics, minimally invasive gynecological surgery clinics, pelvic floor dysfunction clinics, early pregnancy clinics, high-risk obstetric clinics, and Down syndrome biochemical screening clinics. The average annual number of inpatient surgical cases is nearly 2,000, including complex open surgeries; laparoscopic surgeries, including single-port laparoscopy, transvaginal single-port laparoscopic surgery (V-NOTES), and Da Vinci robotic surgery; hysteroscopy; colposcopy; and various other advanced and high-end gynecological surgeries. Since 2018, the department has been involved in the construction of the "Shanghai Critical Maternal Rescue and Consultation Center" and the "Shanghai Prenatal Diagnosis (Screening) Center." Over the past three years, relying on Zhongshan Hospital's strong multidisciplinary diagnostic and treatment capabilities, the department has treated hundreds of patients, including those with contraindications to pregnancy, high-risk pregnant women, and critically ill pregnant women, all of whom were successfully rescued with both mother and child safe. With the care and support of leaders at all levels, the entire medical and nursing staff of the department adhere to excellent medical traditions, uphold integrity and innovation, and continuously improve the department's rules, regulations, and medical and nursing routines. The department insists on clinical diagnosis and treatment as its foundation while simultaneously developing teaching and research work. Over the years, it has undertaken teaching responsibilities at the Fudan University School of Clinical Medicine and, as a Shanghai standardized residency training base, has cultivated a large number of high-quality obstetrics and gynecology medical professionals. In terms of scientific research, relying on Zhongshan Hospital's central laboratory, the department has undertaken multiple national and municipal research projects over the years, with several department members serving as editorial board members for international and domestic core journals.
