［Abstract］　Objective　To explore the clinical effect and prevention of postoperative complications of one-stage breast reconstruction with pedicled omental flap after endoscopic radical breast-conserving surgery for breast cancer. Methods　The clinical data of 32 patients with early breast cancer who were admitted to Zhujiang Hospital, Southern Medical University from May 2017 to March 2023 were retrospectively analyzed. All the patients underwent one-stage breast reconstruction with pedicled omental flap after endoscopic radical breast-conserving surgery for breast cancer. The baseline data, surgical results, postoperative complications, recurrence and metastasis of the patients were summarized. Results　The pedicled omental flaps were successfully obtained with the assistance of laparoscopy in all the patients, and no cases were converted to open surgery midway. The postoperative follow-up period was 4-71 months, and the mean follow-up period was 21.34 months. Postoperative incisional hernia of the abdominal wall occurred in 1 case(3.13%) and incisional infections in 2 cases(6.25%). The total complication rate was 9.38%(3/32). The patients with incisional infections were improved after anti-infections and regular dressing changes. The patient with postoperative incisional hernia of the abdominal wall had no relapse after incisional hernia repair surgery. Conclusion　Breast reconstruction surgery can achieve ideal reconstruction results after obtaining the pedicled omental flaps under the assistance of laparoscopy, but the corresponding complications can also occur. Improving the operation procedure during the surgery and taking specific measures in time after surgery can reduce the occurrence of complications and obtain good surgical results.]]> 2023/10/12 10:25:14 LAI Jia-xin, LIN Xiao-tian, HE Lin-yun, et al. 5true ［Abstract］　Objective　To analyze the feasibility and clinical effects of transaxillary approach single-port pneumatic lumpectomy for benign breast tumors. Methods　The clinicopathological data of 62 patients who underwent transaxillary approach single-port pneumatic lumpectomy for benign breast tumors in the Department of Breast Surgery of Foshan Nanhai District People′s Hospital from June 2021 to July 2023 were retrospectively analyzed and the success rate of operation, number of resected tumors, operation time,intraoperative conditions, postoperative complications, and clinical outcomes were analyzed and summarized. Results　All of the 62 patients were successfully operated, and a total of 144 benign tumors were resected in the 62 patients with an average of (2.1±1.2)tumors. The average operation time was (67.0±3.2)minutes for unilateral breast and (111.0±7.6)minutes for bilateral breasts. The time to resect a single tumor in the lateral quadrant［(27.0±1.9)minutes］ was significantly longer than that in the medial quadrant［(20.0±2.5)minutes］(t=10.768, P<0.001). The time to resect a single tumor in the diameter of more than 5.0 cm［(25.0±1.8)minutes］ was significantly shorter than that in the diameter between 2.0 cm and 5.0 cm［(30.0±2.9)minutes］(t= 6.781, P<0.001). The intraoperative bleeding volume was less than 20 ml in all the 62 patients, and there were no cases of postoperative bleeding, incision infection and poor healing. Among the 62 patients, 14 patients had local effusion of more than 10 ml on the first day after surgery, which disappeared after fluid aspiration and pressure dressing; three patients had upper extremity dysfunction in their lesion sides, which recovered after 3-4 weeks of acupuncture and physiotherapy; no patients had tumor recurrence after a follow-up of 6 months, and the patients′ satisfaction rate was 100.00%. Conclusion　Transaxillary approach single-port pneumatic endoscopic-assisted lumpectomy for benign breast tumors is a new and effective technique for the treatment of breast diseases. It can not only completely remove the lesions, but also conceal the scars with good cosmetic results after surgery.]]> 2023/10/12 10:25:14 YAO Cheng-cai, LIU Chang-chun, HUANG Wen-jian 4true ［Abstract］　Objective　To explore the surgical method and clinical application value of postmastectomy one-stage prosthesis implantation combined with breast reconstruction with pectoralis fascia through a single incision and stratified aeration with endoscopy. Methods　The clinical data of two patients with early breast cancer were retrospectively analyzed. Subcutaneous glandectomy was performed using endoscopy technique by an approach of lateral chest wall incision or axillary incision, and then breast reconstruction with pectoral fascia combined with prosthesis implantation was completed using total endoscopy technique. The surgical complications were observed, and the patients′ preoperative and postoperative satisfaction rates were investigated by BREAST-Q survey questionnaire. Results　The operations were successfully completed in the two cases. No complications were observed, such as postoperative infection, nipple areola or skin flap ischemic necrosis, prosthesis exposure or removal, postoperative motion abnormalities, postoperative chest wall pain, capsule contracture and “ripple” sign. The results of BREAST-Q survey questionnaire showed that all the patients were satisfied with their breast appearance, except for occasional pulling sensation, and no other chest wall discomfort was reported. The postoperative social psychological status and sexual health status in the two patients were not significantly reduced compared with those before surgery. Conclusion　One-stage prosthesis implantation combined with breast reconstruction with pectoralis fascia through a single incision can provide a new option for breast cancer patients who can not paid for patches. This method solves the technical points of separating the pectoral fasciatotally using endoscopy technique and is worth further exploration and research for some suitable populations.]]> 2023/10/12 10:25:14 XU Biao, WANG Lei, LUO Wei, et al. 3true ［Abstract］　Objective　To explore the application effect of single-port insufflation endoscopic nipple-sparing mastectomy on early-stage breast cancer. Methods　A total of 40 patients who underwent nipple-sparing mastectomy at the People′s Hospital of Guangxi Zhuang Autonomous Region between July 2021 and August 2022 were selected. They were divided into two groups according to different surgical approaches: the laparoscopic group(receiving single-port insufflation endoscopic nipple-sparing mastectomy, 20 cases) and the open group(receiving open nipple-sparing mastectomy, 20 cases). The surgical time, intraoperative blood loss, incision length, postoperative hospital stay, postoperative drainage volume, complication rate, Functional Assessment of Cancer Therapy-Breast(FACT-B) scores and satisfaction ratings for cosmetic outcomes 6 months after surgery were compared between the two groups. Results　The operations were successfully completed in both groups and the patients recovered and were discharged from the hospital. The incision length in the laparoscopic group was shorter than that in the open group, but the surgical time in the laparoscopic group was longer than that in the open group, and the postoperative drainage volume in the laparoscopic group was larger than that in the open group, and the differences were significant(P<0.05). The FACT-B scores and satisfaction ratings for cosmetic outcomes 6 months after surgery in the laparoscopic group were significantly higher than those in the open group(P<0.05). There were no statistically significant differences between the two groups in terms of intraoperative blood loss, postoperative hospital stay and the incidence of postoperative complications(P>0.05). Conclusion　Single-port laparoscopic nipple-sparing total mastectomy is safe and effective, offering superior cosmetic results and higher patients′ satisfaction rate. Moreover, it improves the patients′ quality of life and mental health.]]> 2023/10/12 10:25:14 XU Jin-an, ZHAO Ying-zhu, LI Li-hui, et al. 2true ［Abstract］　Breast cancer has become the most prevalent cancer in women globally, and its main form of treatment is surgery. Traditional breast surgery has a substantial impact on the patients′ quality of life because of its sizeable incision and multiple and more serious complications. In the continuous pursuit of minimally invasive surgery today, this surgical procedure is no longer able to meet the aesthetic needs of female patients. Endoscopic surgery for breast cancer is made to be feasible by the advancement of endoscopic surgery and the iteration of equipments. The emergence and improvement of both liposoluble and non-liposoluble techniques have laid the foundation for the development of endoscopic surgery for breast cancer and their short and medium-term effects and safety are encouraging. The ongoing improvement of surgical techniques, and the emergence of various consensuses and recommended guidelines further reduces the learning cost, which is conducive to the further promotion and development of endoscopic breast surgery techniques. The emergence of laparoendoscopic single-site surgery and robot-assisted breast surgery in China marks the further development of endoscopic breast surgery techniques and enters the international leading ranks. This paper reviews the progress of the related studies on endoscopic surgery for breast cancer.]]> 2023/10/12 0:00:00 DONG Ling-guang, ZHAO Ying-zhu, MO Zong-ming, et al. 1true
