Objective:To compare the clinical outcomes of immediate breast reconstruction using latissimus dorsi flap with implant versus mesh with implant based on BREAST-Q evaluation.Methods:From the clinical database of the First Affiliated Hospital of Nanjing Medical University, the patients who underwent immediate breast reconstruction after total mastectomy from January 2020 to December 2023 were selected as the research subjects. All breast reconstruction surgeries were performed by the same surgeon. Patients were divided into two groups according to surgical methods: the latissimus dorsi muscle flap combined with implant immediate breast reconstruction group (LD group) and the mesh combined with implant immediate breast reconstruction group (mesh group). Patients were followed up in outpatient clinics or by telephone one year after surgery. The BREAST-Q was used to evaluate the surgical outcomes of both groups from four dimensions: psychosocial well-being, sexual well-being, chest-physical well-being, and breast satisfaction. The score range for each dimension was 0-100, with higher scores indicating greater patient satisfaction with quality of life and surgical outcomes. Statistical analysis was performed using SPSS 22.0 software. Normally distributed measurement data were expressed as Mean ± SD, and comparisons between the two groups were performed using independent sample t-test. Count data were expressed as number of cases and percentages, and comparisons between groups were performed using chi-square test or Fisher’s exact test. P<0.05 was considered statistically significant. Results:A total of 123 patients were included, with 59 patients in the LD group and 64 patients in the mesh group. In the LD group, the mean age was (37.7±7.0) years, body mass index (BMI) was (22.6±2.6) kg/m 2, and clinical tumor staging showed 2, 22, 30, and 5 cases for stages 0, Ⅰ, Ⅱ, and Ⅲ, respectively. In the mesh group, the mean age was (39.1±7.0) years, BMI was (22.6±2.8) kg/m 2, and clinical tumor staging showed 1, 25, 38, and 0 cases for stages 0, Ⅰ, Ⅱ, and Ⅲ, respectively. There were no statistically significant differences between the two groups in baseline characteristics including age, BMI, and clinical tumor staging (all P>0.05). One year after surgery, the BREAST-Q result showed no statistically significant differences between the LD group and mesh group in psychosocial well-being [(83.0±19.8) points vs. (80.8±19.3) points] and sexual well-being [(62.1±30.4) points vs. (65.8±25.6) points] (all P>0.05). However, the LD group had lower chest-physical well-being scores than the mesh group [(40.6±9.7) points vs. (45.1±9.6) points, P<0.05], while breast satisfaction scores were higher in the LD group than in the mesh group [(68.0±17.8) points vs. (59.8±12.6) points, P<0.01]. Conclusion:Immediate breast reconstruction by both latissimus dorsi flap with implant and mesh with implant can improve patients’ psychosocial and sexual well-being by enhancing breast appearance. However, LD technique provides better breast satisfaction, while the mesh technique offers advantages in physical well-being of the chest wall and upper body. Surgeons should select the most appropriate breast reconstruction technique based on patients’ anatomical conditions, treatment history, and individual needs to optimize postoperative quality of life and satisfaction.

Objective:To evaluate the short-term efficacy of endoscopic-laparoscopic regional gastric resection combined with sentinel lymph node basin dissection in patients with early-stage gastric cancer.Methods:This is a retrospective case series study. Data of 17 consecutive early gastric cancer patients from a prospective cohort at Beijing Friendship Hospital,Capital Medical University were analyzed between August 2023 and August 2024. Sixteen cases were from the department of general surgery and 1 from the department of gastroenterology. The cohort included 9 males and 8 females,with a mean age of 61.4 years (range: 46 to 79 years). Clinical data,including demographics,pathological features,surgical procedures,and follow-up outcomes,were collected through medical records and databases. All patients were followed for over 3 months,with follow-up ending on December 5,2024.Results:A total of 17 patients were involved. Among them, 5 patients underwent endoscopic submucosal dissection (ESD) combined with laparoscopic sentinel lymph node dissection (LSBD),and another 3 patients who underwent complete ESD resection received LSBD due to pathological stage meeting the expanded indications. 6 patients who underwent non-curative ESD resection received laparoscopic gastric regional resection (LRG) combined with LSBD,and another 3 patients directly received LRG combined with LSBD. The average number of sentinel lymph nodes dissected before surgery ( M(IQR)) was 8.9 (4.5) (range: 4 to 21),and the detection rate and accuracy rate were both 100%. Postoperative pathology confirmed that there was no metastasis in the sentinel lymph nodes of 5 patients who underwent ESD combined with LSBD and 3 patients who underwent LSBD after complete ESD resection. The vertical and horizontal margins of ESD were all negative. One patient was an absolute indication for ESD. For the 6 patients who underwent non-curative ESD resection combined with LRG and LSBD,the horizontal margins were all negative. Two patients showed 1 metastasis in each of the 21 and 9 sentinel lymph nodes during the operation,and additional distal gastrectomy was performed during the operation. Postoperatively,73 and 39 lymph nodes were retrieved respectively. The former had 1 additional metastasis,while the latter had no metastasis. Among the 3 patients who underwent direct LRG combined with LSBD,the horizontal margins were negative. One patient was confirmed as an absolute indication for ESD by postoperative pathology,and one patient had 1 metastasis in 8 sentinel lymph nodes during the operation,and additional distal gastrectomy was performed. Postoperatively,there was no metastasis in 54 lymph nodes. All patients had no complications such as infection,bleeding,perforation,or death after surgery. Among the 14 patients who did not receive additional radical surgery,they were able to pass gas and defecate within 3 days after surgery,with an average hospital stay of 6 days. The nutritional indicators and gastric radionuclide emptying imaging half-emptying time were similar to those before surgery at 3 months after surgery. Conclusions:Laparoscopic and endoscopic cooperative regional gastrectomy with sentinel lymph node basin dissection has the advantages of minimal invasiveness,preservation of gastric function,and precise treatment. It maybe suitable for patients with early-stage gastric cancer at high risk of lymph node metastasis and has good short-term efficacy.

Background::Hepatitis B poses a heavy burden for children in China, however, the national studies on the distributional characteristics and health care costs of children with severe hepatitis B is still lacking. This study aimed to analyze the disease characteristics, health economic effects, and medical cost for children with severe hepatitis B in China.Methods::Based on patient information in the Hospital Quality Monitoring System, cases with severe hepatitis B were divided into four groups according to age, and the etiology and symptoms of each group were quantified. The cost of hospitalization was calculated for cases with different disease processes, and severity of disease. The spatial aggregation of cases and the relationship with health economic factors were analyzed by Moran’s I analysis. Results::The total number of children discharged with hepatitis B from January 2016 to April 2022 was 1603, with an average age of 10.5 years. Liver failure cases accounted for 43.48% (697/1603) of total cases and cirrhosis cases accounted for 11.23% (180/1603). According to the grouping of disease progression, there were 1292 cases without associated complications, and the median hospitalization cost was $818.12. According to the spatial analysis, the aggregation of cases was statistically significant at the prefectural and provincial levels in 2019, 2020, and 2021 (all P <0.05). The number of severe cases was negatively correlated with gross domestic product (Moran’s I <0) and percentage of urban population (Moran’s I <0), and positively correlated with the number of pediatric beds per million population (Moran’s I >0). Conclusion::The number of severe hepatitis B cases is low in areas with high gross domestic product levels and high urban population ratios, and health care costs have been declining over the years.
