Objective To introduce a simple preoperative risk score for esophageal cancer (PRSEC) and its relationship with the prognosis of patients who underwent resection of esophageal carcinoma. Methods We retrospectively analyzed the clinical data of 498 patients receiving resection of esophageal carcinoma between 2005 and 2015 in our hospital. They were divided into three groups (PRSEC1, PRSEC2 and PRSEC3 groups) according to the results of PRSEC (revised cardiac risk index, model for end-stage liver disease score and pulmonary function test). Their overall survival (OS) and disease-free survival (DFS) were measured to find the relationship between the PRSEC and prognosis of patients. Results The mortality, morbidity, DFS and OS were correlative with the PRSEC. Therefore the PRSEC can be used to predict the short-term outcome. The patients with score 2 or 3 had higher risk of mortality and morbidity than those with score 1. In addition, the DFS and OS of patients with higher score were shorter (P<0.001). Conclusion The PRSEC is easy and efficient and can predict the morbidity, mortality, and long-term outcomes for the patients with resection of esophageal carcinoma.
ObjectiveTo review the characteristics of patients who underwent atrioventricular septal defects (AVSD) repair with prosthetic valve ring implantation in our hospital, and to analyze the safety and effectiveness of this intervention.MethodsThe clinical data of all patients diagnosed with AVSD who received surgery repair and prosthetic valve ring implantation from January 1, 2018 to July 12, 2020 in Guangdong Provincial People's Hospital were collected and analyzed. There were 22 patients with 9 males and 13 females at a median age of 35.00 (14.10, 53.00) years. There were 9 (40.9%) patients with prosthetic half or full rings placed on the left atrioventricular valve and 18 (81.8%) patients with prosthetic half or full rings placed on the right atrioventricular valve. ResultsThe median postoperative hospital stay was 7.00 (6.00, 8.80) d, and the postoperative mechanically assisted ventilation time was 11.00 (6.25, 19.00) h. There were 2 (9.1%) patients of moderate or higher postoperative atrioventricular valve regurgitation, 1 on the left and 1 on the right. There was one patient (4.5%) of the postoperative residual septal defect. There was no left ventricular inflow or outflow tract obstruction and no postoperative residual atrial septal defect during the follow-up of 152.00 (124.00, 1 030.00) d.ConclusionImplantation of a prosthetic ring is safe and effective in patients with AVSD, and the structural strength of the ring may be improved after the implantation. The physiological development of the AVSD annulus after prosthetic ring implantation and the results of long-term follow-up needs further attention.
Objective To compare outcomes after single versus bilateral lung transplantation in patients with end-stage chronic obstructive pulmonary disease (COPD) with retrospective cohort study, and to provide a reference for surgical selection. Methods One hundred and two patients with end-stage COPD who received lung transplantation in Wuxi People's Hospital affiliated to Nanjing Medical University from January 2010 to May 2019 were evaluated, including 97 males and 5 females, aged from 42 to 82 years, with an average age of (59.8±8.0) years. Recipients were divided into single lung transplantation (SLT) group (31 cases) and bilateral lung transplantation (BLT) group (71 cases). Preoperative characteristics, postoperative outcomes, postoperative complications, functional improvement and survival between the two groups were analyzed retrospectively. Results The SLT group were significantly older than the BLT group [(62.6±8.8) years vs. (58.6±7.4) years, P<0.05], which was consistent with the practice mode of single lung transplantation in the elderly patients in this center. The FEV1% predicted and the six‐minute walk distance (6-MWD) in the BLT group were better than those in the SLT group (P<0.05). The cumulative survival rate in 1, 3 and 5 years after operation in the BLT group was higher than that in the SLT group (70.4%, 63.2%, 61.5%, respectively vs. 67.7%, 58.1%, 54.6%, respectively), but there was no statistical difference (P=0.388). The two groups were comparable in other preoperative clinical data (P>0.05). The cold ischemia time and total operation time were shorter in the SLT group than in the BLT group, and the intraoperative blood loss was less than that in the BLT group, but more patients required intraoperative extracorporeal membrane oxygenation support than the BLT group (P<0.05). There were no significant differences in postoperative ventilator support, reoperation, length of intensive care unit stay, postoperative hospital stay, and perioperative mortality (P>0.05). In terms of postoperative complications, the incidence of primary graft dysfunction grades 3 was higher in the SLT group than in the BLT group (35% vs. 8%, P=0.001). There were no significant differences between the two groups in chest complications, airway complications, acute rejection, infection, and bronchial occlusion syndrome (P>0.05). Nine patients (29%) developed acute native lung hyperinflation in the SLT group. ConclusionsBilateral lung transplantation is superior to single lung transplantation in the treatment of end-stage COPD. The advantage is mainly reflected in the simple perioperative management, better functional improvement after operation. Single lung transplantation as a beneficial supplement to double lung transplantation should still be considered in selected patients.
ObjectiveTo explore the influence of sentinel lymph node (SLN) status on the prognosis of elderly breast cancer patients ≥70 years old, and to screen patients who may be exempted from sentinel lymph node biopsy (SLNB), so as to guide clinical individualized treatment for such patients. MethodsA retrospective analysis was made on 270 breast cancer patients aged ≥70 years old who underwent SLNB in the Affiliated Hospital of Southwest Medical University from 2012 to 2021. The clinicopathological characteristics of the total cases were compared according to the status of SLN. Kaplan-Meier method was used to draw the survival curve, and the influence of SLN status on the overall survival (OS) time, local recurrence (LR) and distant metastasis (DM) of patients were analyzed, and used log-rank to compare between groups. At the same time, the patients with hormone receptor (HR) positive were analyzed by subgroup. The differences between groups were compared by single factor χ2 test, and multivariate Cox regression model was used to analyze and determine the factors affecting OS, LR and DM of patients. ResultsThe age of 270 patients ranged from 70 to 95 years, with a median age of 74 years. One hundred and sixty-nine (62.6%) patients’ tumor were T2 stage. Invasive ductal carcinoma accounted for 83.0%, histological gradeⅡ accounted for 74.4%, estrogen receptor positive accounted for 78.1%, progesterone receptor positive accounted for 71.9%, and human epidermal growth factor receptor 2 negative accounted for 83.3%. The number of SLNs obtained by SLNB were 1-9, and the median was 3. SLN was negative in 202 cases (74.8%) and positive in 68 cases (25.2%). Thirty-five patients (13.0%) received axillary lymph node dissection. There was no significant difference in LR between the SLN positive group and the SLN negative group (P>0.05), but the SLN negative group had fewer occurrences of DM (P=0.001) and longer OS time (P=0.009) compared to the SLN positive group. The results of univariate and multivariate analysis suggest that the older the patient, the shorter the OS time and the greater the risk of DM. Analysis of HR positive subgroups showed that SLN status did not affect patient survival and prognosis, but age was still associated with poor OS time and DM. ConclusionsFor patients with invasive ductal carcinoma of breast in T1-T2 stage, HR positive, clinical axillary lymph nodes negative, and age ≥70 years old, SLNB may be exempted. According to the patient’s performance or tumor biological characteristics, patients who need systemic adjuvant chemotherapy may still consider SLNB.
Objective To compare the safety and efficacy of minimally invasive coronary artery bypass grafting (MICS CABG) and traditional CABG in patients with coronary heart disease (CHD) and diabetes mellitus (DM). Methods From 2019 to 2021, the patients who received CABG by the same medical group in the Minimally Invasive Cardiac Surgery Center of Anzhen Hospital were retrospectively enrolled. According to the surgery methods, the patients were divided into two groups: a MICS CABG group and a conventional group. The perioperative and postoperative follow-up data of patients were collected. The main observation results included all cause death events, myocardial infarction, cerebrovascular, revascularization, and adverse wound healing. Results According to the inclusion and exclusion criteria, 140 patients were enrolled, including 66 patients in the MICS CABG group (56 males and 10 females, aged 61.83±8.94 years), and 74 patients in the conventional group (55 males and 19 females, aged 58.61±8.26 years). Compared with the conventional group, patients in the MICS CABG group had longer median surgical time (4.50 h vs. 4.00 h, P=0.005), less intraoperative bleeding (600.00 mL vs. 700.00 mL, P=0.020), and a lower rate of secondary debridement and suturing of surgical wounds (4.5% vs. 16.2%, P=0.023). The median follow-up time was 2.54 years. There was no statistically significant difference in the cumulative incidence of major adverse cardiac and cerebrovascular events (7.6% vs. 5.4%), all-cause mortality (0 vs. 0), myocardial infarction (3.0% vs. 2.7%), cerebrovascular events (4.5% vs. 2.7%), and revascularization (0 vs. 0) between the two groups of patients during the postoperative follow-up (P>0.05). Conclusion MICS CABG can achieve the same revascularization effect as traditional CABG in patients with CHD and DM. MICS CABG can effectively reduce adverse clinical outcomes or complications such as adverse chest wound healing and slow postoperative recovery of body function in patients with DM.
