ObjectiveTo analyze the short- and long-term therapeutic effects of heart transplantation in children. MethodsA retrospective study was conducted on recipients and donors who underwent heart transplantation at the 7th People’s Hospital of Zhengzhou from May 2018 to August 2023, analyzing their clinical characteristics, surgical data, postoperative complications, and survival rates. ResultsA total of 22 children underwent heart transplantation, including 14 males and 8 females, with a median age of 13.5 (10.0, 15.0) years and a median weight of 41.9 (30.5, 55.4) kg. The primary diseases included: dilated cardiomyopathy in 16 patients, hypertrophic cardiomyopathy in 1 patient, myocardial dysplasia in 3 patients, right ventricular dysplasia in 1 patient, and congenital heart disease with abnormal coronary artery origin in 1 patient. The median age of the donors was 21.0 (13.0, 29.0) years, and the median weight was 50.5 (47.3, 75.0) kg. The blood types of the donors and recipients were the same, with type A in 10 patients, type B in 5 patients, type O in 5 patients, and type AB in 2 patients. Before transplantation, all children had a New York Heart Association cardiac function grade Ⅳ, with 1 patient assisted by intra-aortic balloon pump (IABP), 3 patients assisted by extracorporeal membrane oxygenation (ECMO), 2 patients assisted by continuous renal replacement therapy (CRRT), and 2 patients on mechanical ventilation. Nine patients met the criteria for emergency child status allocation, and the panel reactive antibody level in the patients was<10%. The median cold ischemic time of the donor heart was 355.0 (262.0, 395.5) min, the median aortic cross-clamping time was 45.0 (38.3, 51.3) min, the median mechanical ventilation time was 22.5 (16.8, 52.5) h, the median postoperative hospital stay was 29.5 (20.0, 43.0) d, and the median intensive care unit stay was 6.0 (5.0, 8.3) d. After surgery, 4 patients were assisted by ECMO, 2 patients by CRRT, and 7 patients developed complications, including lung fungal infection in 6 patients, liver and kidney dysfunction in 1 patient, local wound non-union and mediastinal infection in 1 patient, and multiple organ failure in 1 patient. Kaplan-Meier curve analysis showed that the survival rates of children after surgery were 91.3% at 1 year and 3 years; the survival rates of adult heart transplant recipients at our center were 86.7% and 73.8% at 1 year and 3 years, respectively, indicating that the survival rate of children with heart transplantation was higher than that of adult patients. ConclusionHeart transplantation is an effective treatment for end-stage heart failure in children, and the short- and long-term survival rates of children with heart transplantation are superior to those of adults. There are still many difficulties to be solved in pediatric heart transplantation, requiring joint efforts from society and the medical community.
Objective To use a meta-analysis method to establish quantitatively the association between the HER-2/neu gene amplification/enhanced protein expression status and the 5-year post-operative survival rate or median survival time in women with epithelial ovarian carcinoma. Methods We searched and screened Chinese and English literature published since 1989 to collect all retrospective cohort studies on the prognostic significance of HER-2/neu status in this population. The survival data were analyzed using Ludwig’s centered signed rank and the DerSimonian-Laird method. Results In total, 25 studies involving 3 251 patients were included. HER-2/neu was positive in 27.1% (95%CI 0 to 54.8%) of patients, which was not related to the pathological stage, type or grade of epithelial ovarian carcinoma. In HER-2/neu positive cases, the median survival time was shortened by 0.65 years, and the 5-year survival rate was lowered. The hazard ratio (HR) for mortality was 1.22 (95%C 1.09 to 1.36). By subgroup analysis, HER-2/neu protein expression was found to be most significant in prognostic assessment. Patients with a b positive value of HER-2/neu had an increased HR for the 5-year survival; and platinum-based chemotherapy was demonstrated to be less effective in HER-2/neu positive ovarian carcinoma. Conclusion In gynecological oncology, it is reasonable to measure HER-2/neu as a routine pathological marker to predict a patient’s prognosis and to determine the most appropriate adjuvant chemotherapy regimen.
ObjectiveTo investigate the short-term follow-up results of inflatable mediastinoscopy combined with laparoscopy in the treatment of esophageal cancer.MethodsClinical data of 102 patients with esophageal cancer who underwent minimally invasive esophagectomy were enrolled in our hospital from January 2017 to January 2019. Patients were divided into two groups according to different surgical methods, including a single-port inflatable mediastinoscopy combined with laparoscopy group (group A, n=59, 53 males and 6 females, aged 63.3±7.6 years, ranging from 45 to 75 years) and a video-assisted thoracoscopy combined with laparoscopy group (group B, n=43, 35 males and 8 females, aged 66.7±6.7 years, ranging from 50-82 years). The short-term follow-up results of the two groups were compared.ResultsCompared with the group A, the rate of postoperative pulmonary complication of the group B was significantly lower (18.64% vs. 4.65%, P<0.05). There was no significant difference between the two groups in other postoperative complications (P>0.05). The 6-month, 1-year, and 2-year survival rates were 96.61%, 89.83%, and 73.33%, respectively in the group A, and were 95.35%, 93.02%, and 79.17%, respectively in the group B. There was no significant difference in short-term survival rate after operation (P>0.05).ConclusionIn the treatment of esophageal cancer, the incidence of pulmonary complications of inflatable mediastinoscopy combined with laparoscopy is lower than that of traditional video-assisted thoracoscopy combined with laparoscopy, and there is no significant difference in other postoperative complications or short-term survival rate between the two methods. Inflatable mediastinoscopy combined with laparoscopy for radical esophageal cancer is a relatively safe surgical method with good short-term curative effects, and long-term curative effects need to be further tested.
ObjectiveTo evaluate the effectiveness of preoperative immunosuppressive therapy combined with surgical intervention. MethodsA retrospective study was conducted on Behçet's disease patients who underwent cardiac surgery at Guangdong Provincial People's Hospital from 2012 to 2021. Patients were divided into immunosuppressive group and non-immunosuppressive group based on whether they received immunosuppressive therapy before surgery. The complications and long-term survival rates of the two groups were analyzed. ResultsA total of 28 patients were included, among which 2 patients underwent reoperation, a total of 30 surgeries were performed, including 16 males (53.3%), and the confirmed age was 37 (31, 45) years old. There were 15 surgeries in the immunosuppressive group and 15 surgeries in the non-immunosuppressive group. Compared with the non-immunosuppressive group, the incidence of complications during hospitalization in the immunosuppressive group was lower (13.3% vs. 53.3%, P=0.008). One patient died in hospital, and the rest were discharged and followed up, with a median follow-up time of 38.7 (15.1, 57.3) months, and there was no statistically significant difference in long-term survival rate between the two groups (26.7% vs. 6.7%, P=0.158). There was no statistically significant difference in the cumulative incidence of complications one month (20% vs. 53%, P=0.058) and one year (27% vs. 60%, P=0.065) after surgery between the immunosuppressive group and the non-immunosuppressive group, but there was a statistically significant difference in the cumulative incidence of complications three years after surgery (47% vs. 92%, P=0.002). ConclusionSurgical treatment can save lives in Behçet's disease patients with cardiovascular diseases, but the incidence of postoperative complications is high. Timely use of immunosuppressants before cardiovascular surgery can reduce the incidence of postoperative complications.
ObjectiveTo compare the long-term outcomes of laparoscopic hepatectomy (LH) and open hepatectomy (OH) in the treatment of hepatocellular carcinoma (HCC), and to discuss the recurrence patterns of HCC after surgery. MethodsPatients with HCC who underwent hepatectomy and met inclusion and exclusion criteria from January 2015 to December 2018 were retrospectively enrolled, then were divided into LH and OH groups according to surgical methods. The results of HCC recurrence after LH and OH were compared after 1∶1 propensity score matching between the two groups. The potential risk factors for recurrence were assessed by Cox proportional hazards regression and a nomogram was constructed. ResultsA total of 977 patients with HCC who underwent hepatectomy were enrolled. Of these, 385 underwent LH and 592 underwent OH. After 1∶1 propensity score matching, 323 patients were enrolled in each group for analysis. The tumor recurrences were found in 124 patients (38.4%) and 118 patients (36.5%) and the median tumor free survival time was 10 months and 9 months in the LH group and OH group, respectively. The most common recurrence pattern was the intrahepatic recurrence, and the most common treatment was the transarterial chemoembolization. There was no significant difference of the relapse free survival curve between the LH and OH groups (P=0.763). In the entire cohort, no patient had recurrence or metastasis of specimen removal incisions or Trocar pores. No significant differences in the recurrence pattern and treatment between the LH and OH groups (P>0.05). Cox proportional hazards regression analysis showed that the age ≤60 years old, grade 2 of albumin-bilirubin grade, postoperative alpha fetoprotein >8 μg/L, tumor diameter ≥5 cm, multiple tumors, and low differentiation increased the recurrence of HCC after LH (P<0.05). The nomogram including these factors and combining with clinical practice was constructed, its consistent index for predicting the recurrence of HCC after LH was 0.704 [95%CI (0.659, 0.753)]. ConclusionIntrahepatic recurrence is still the most common pattern of postoperative HCC recurrence, and LH doesn’t increase risk of incision recurrence or implantation.
ObjectiveTo investigate the impact of primary tumor site on prognosis of colorectal cancer after radical resection in different stages.MethodsFour hundreds and twenty patients with colorectal cancer in our hospital from Jan. 2008 to Dec. 2016 were selected as study subjects, all patients were confirmed by pathology. According to the location of colorectal cancer, the patients were divided into rectum group (n=220), left colon group (n=105) and right colon group (n=95). The difference of clinicopathological features of patients with different group were compared. The risk factors affecting the prognosis of colorectal cancer patients were analyzed by single factor and multi factor unconditional Cox regression analysis, and the survival curve was drawn by Kaplan-Meier method, and the difference test was carried out by log-rank method.ResultsThere were no significant differences between the three groups in age, BMI, smoking history, alcohol history, family history, vascular tumor thrombus, N staging, tumor diameter, nerve invasion and cancer nodule (P>0.05). There were significant differences in sex, pathological type, anterior intestinal obstruction, TNM staging, T staging and M staging (P<0.05). The results of single factor Cox regression analysis showed that sex, pathological type, anterior intestinal obstruction, TNM staging, T staging, M staging, primary tumor site, nerve invasion and cancer nodule were the risk factors for the prognosis of the patients (P<0.05). Multivariate Cox regression analysis showed that TNM staging, location of primary tumor and nerve invasion were risk factors affecting prognosis of patients (P<0.05). The total 5-year survival rate of the rectal group was 80.45% (177/220), the total 5-year survival rate of the left hemicolon group was 67.62% (71/105), and the total 5-year survival rate of the right hemicolon group was 68.42% (65/95). The survival curves of Kaplan-Meier showed that the difference between the three groups was statistically significant (P<0.05).ConclusonsThe 5-year survival rate of patients with rectal cancer is significantly higher than that of patients with left colon cancer and right colon cancer. For patients with different stage of colorectal cancer after radical resection, the prognosis of colorectal cancer can be predicted by the location of primary tumor.
Objective To evaluate the impact of portal or systemic venous pancreas graft drainage on patient and graft outcomes following simultaneous pancreas kidney transplantation (SPK). Methods We searched The Cochrane Library (2008, Issue 1), PubMed (1970 to Feb 2008) and EMBASE (1974 to Feb 2008) to find studies concerning the effect of systemic versus portal venous pancreas graft drainage on patient and graft outcomes. Meta-analyses were conducted using The Cochrane Collaboration’s RevMan 4.2 software. Results Three RCTs involving 401 simultaneous pancreas kidney transplants were included in our meta-analysis. Statistically significant differences were only observed in 3- and 5-year pancreas graft survival rates (P=0.03 and P=0.05). No significant difference was noted in patient or kidney graft survival rates. Conclusion Currently available evidences from RCTs does not support the effectiveness of portal drainage in preventing thrombosis, rejection or infection after SPK. Large-scale, long-term and appropriately designed RCTs are required to conclude whether portal and systemic drainage in pancreas transplantation are equivalent in terms of patient and graft survival.
ObjectiveTo compare the 5-year survival rates between two different follow-up patterns of postoperative stage Ⅰ-ⅢA non-small cell lung cancer (NSCLC) patients.MethodsPathological stage Ⅰ-ⅢA NSCLC 11 958 patients who underwent surgical resection and received follow-up within 6 months after initial diagnosis through telephone follow-up system were included in nine hospitals from July 2014 to July 2020. The patients were divided into two groups including a proactive follow-up group (n=3 825) and a passive follow-up group (n=8133) according to the way of following-up. There were 6 939 males and 5 019 females aged 59.8±9.5 years. The Kaplan-Meier and Cox proportional hazards regression model were used.ResultsThe median follow-up frequency was 8.0 times in the proactive follow-up group and 7.0 times in the passive follow-up group. The median call duration was 3.77 minutes in the proactive follow-up group and 3.58 minutes in the passive follow-up group. The 5-year survival rate was 81.8% and 74.2% (HR=0.60, 95CI 0.53-0.67, P<0.001) in the proactive follow-up group and the passive follow-up group, respectively. Multivariate analysis showed that follow-up pattern, age, gender and operation mode were independent prognostic factors, and the results were consistent in all subgroups stratified by clinical stages.ConclusionThe proactive follow-up leads to better overall survival for resected stage Ⅰ-ⅢA NSCLC patients, especially in the stage ⅢA.
Objective To evaluate early to medium-term effectiveness of total hip arthroplasty (THA) in patients with a history of hip preservation surgery with secondary severe osteoarthritis for developmental dysplasia of the hip (DDH). Methods The clinical data of 25 DDH patients (31 hips) who had severe osteoarthritis after hip preservation surgery and received THA between September 2009 and March 2021 were retrospectively analyzed. There were 1 male and 24 females; the age ranged from 18 to 65 years, with an average age of 43 years; 8 hips were classified into Crowe type Ⅰ, 9 hips were type Ⅱ, 3 hips were type Ⅲ, and 11 hips were type Ⅳ. The time between osteotomy and THA ranged from 31 to 51 years, with an average of 31.96 years. Preoperative hip flexion range of motion was (69.31±29.72)°, abduction range of motion was (24.00±14.79)°; and Harris hip score was 45.3±15.5. Postoperative Harris hip score, hip range of motion, complications, radiographic findings, and implant survival rate were analyzed. Results Patients in both groups were followed up 2-132 months, with an average of 51 months. During the follow-up, periprosthetic fracture occurred in 1 case; there was no complication such as dislocation, periprosthetic infection, nerve palsy, or deep vein thrombosis. At last follow-up, the hip flexion range of motion was (109.52±11.17)°, abduction range of motion was (41.25±5.59)°, showing significant differences when compared with preoperative values (t=8.260, P=0.000; t=6.524, P=0.000). The Harris hip score was 91.5±4.1, and the difference was significant when compared with preoperative score (t=11.696, P=0.000); among them, 13 cases were excellent and 12 cases were good. Radiographic evaluation showed that the center of acetabular rotation moved up 0-18 mm (mean, 6.35 mm). The cup abductor angle was 28°-49° (mean, 37.74°) and the coverage rate was 69.44%-98.33% (mean, 81.04%). All femoral stems were fixed in neutral position without varus or valgus. No osteolysis, radiolucent line, or implant migration was observed. By the end of follow-up, none of the patients underwent revision and the survival rate of prothesis was 100%. ConclusionTHA is still the gold standard for the treatment of DDH patients with secondary osteoarthritis after hip preservation surgery. The postoperative joint function can be rapidly restored, the patients’ quality of life can significantly improve, and the early to medium-term survival rate of the prosthesis is satisfactory.
ObjectiveTo define the patient characteristics and perioperative management, and to define the mortality and its risk factors after arterial switch operation (ASO).MethodsWe conducted a bidirectional cohort study with 571 consecutive patients undergoing ASO from 1997 to 2016 in our hospital. We enrolled patients who underwent ASO before 2012 retrospectively and after 2012 prospectively and followed up all the patients prospectively. Demographic characteristics, clinical information and mortality of these patients were summarized. Joinpoint regression analysis was used to identify the time trend of the overall mortality. Kaplan-Meier survival analysis was used to evaluate the mid- and long-term survival rate after ASO. Cox proportional hazards regression models were used to explore the potential factors associated with mortality. The cumulative incidence of complications after ASO was predicted using competing risk models.ResultsSeveral aspects of patients’ characteristics and perioperative management in our center differed from those in the developed countries. The overall mortality and in-hospital mortality after ASO was 16.3% and 15.1%, respectively. The overall cumulative survival rate at 5, 10 and 15 years after ASO was 83.3%, 82.8% and 82.8%, respectively. A significant decrease of overall mortality from 1997 to 2016 was observed. Independent risk factors of mortality included earlier ASO (1997-2006), single or intramural coronary anatomy and longer cardiopulmonary bypass time. Ten years after ASO, re-intervention, arrhythmia, pulmonary and anastomotic stenosis were the most common complications with a cumulative incidence over 10%.ConclusionSignificant improvements in the results of the ASO were observed and the postoperative mortality rate is close to reports from developed countries. Nonetheless, we have identified the need for further improvement in the early and late postoperative periods after ASO. Pulmonary stenosis, anastomotic stenosis and arrhythmia should be paid attention to during the long-term follow-up after ASO.
