Twenty five children with congenital biliary dilatation were treated with hepatico-jejuno-duodenostomy following excision of choledochal cysts between 1983 and 1985. The age ranged from two months to eleven years. The last follow-up ranged from 6-9 years (mean 7.5 years). All patients were free of jaundice with normal growth and development and none had peptic ulcer. The results from the last follow-up was better than that of the first one. This procedure was safe, effective and physiologically appealing.
Objective To investigate the long-term effectiveness of Ni-Ti memory alloy tripod fixator in the treatment of Kienböck disease. Methods The clinical data of 22 patients with Kienböck disease who were treated with Ni-Ti memory alloy tripod fixator between January 2011 and September 2013 and followed up more than 10 years was retrospectively analyzed. There were 14 males and 8 females with an average age of 45 years (range, 20-64 years). The Lichtman staging was stage Ⅲb. According to AO/Association for the Study of Internal Fixation (AO/ASIF) classification, there were 6 cases of type B1, 2 cases of type B2, 10 cases of type B3, and 4 cases of type C2. The disease duration ranged from 18 to 50 months, with an average of 30.7 months. The operation time, intraoperative blood loss, and complications were recorded. Wrist height ratio and scapholunate angle were measured by wrist anteroposterior and lateral X-ray films before and after operation. The grip strength of bilateral hands was measured by Jamar dynamometer. The wrist pain was evaluated by visual analogue scale (VAS) score, and the wrist function was evaluated by Mayo score, and the radial deviation, ulnar deviation, dorsiflexion, and palmar flexion range of motion of wrist were measured. Results The operation time was 45-60 minutes, with an average of 52.21 minutes; the intraoperative blood loss was 50-60 mL, with an average of 58.63 mL. No nerve or blood vessel injury occurred during operation. All patients were followed up 10-13 years (mean, 11.3 years). X-ray films at 3 months after operation showed that the density of lunate bone was lower than that before operation. Satisfactory fusion of the scapho-trapezio-trapezoeid joint was achieved at 3-6 months after operation (mean, 4.5 months), and the wrist height ratio and the scapholunate angle after fusion significantly improved when compared with those before operation (P<0.05). Wrist pain relieved, scaphoid rotation and dislocation improved, and no radiocarpal joint degeneration was found during follow-up, and no internal fixator loosening, breakage, or lunate bone necrosis occurred. At last follow-up, the wrist radial deviation, ulnar deviation, dorsiflexion, and palmar flexion range of motion, VAS score, and grip strength of the affected side significantly improved when compared with those before operation (P<0.05); the grip strength of the affected side recovered to 99.00%±1.25% of the healthy side. Mayo score ranged from 72 to 93, with an average of 85; 14 cases were rated as excellent, 5 good, and 3 satisfactory, the excellent and good rate was 86.4%. ConclusionIn the treatment of stage Ⅲb Kienböck’s disease, the scapho-trapezio-trapezoeid joint usion using Ni-Ti memory alloy tripod fixator can effectively reduce pain, improve hand function, and prevent further deterioration, and achieve good long-term effectiveness.
Objective To compare long-term outcomes following mitral valvuloplasty (MVP) and mitral valve replacement (MVR) for native valve endocarditis (NVE). Methods Between November 1993 and August 2016, consecutive 101 patients with NVE underwent mitral surgery in our department, MVP for 52 patients and MVR for 49 patients. There were 69 males and 32 females at age of 38.1±14.9 years. The mean follow-up was 99.4±75.8 months. Results There was no statistical difference in cardiopulmonary bypass time, aortic cross-clamp time, in-hospital mortality, duration of mechanical ventilation, ICU stay or hospital stay after surgery between the two groups. Survival rate at 1, 5, 10, 20 years after surgery was 100.0%, 97.6%, 97.6%, 97.6% for MVP, and 93.5%, 84.3%, 84.3%, 66.2% for MVR with a statistical difference between the two groups (P=0.018). There was no stroke in the patients with MVP during follow-up periods. However, stroke-free survival rate at 1, 5, 10, 20 years after surgery was 100.0%, 93.9%, 89.4%, 70.2% for MVR patients with a statistical difference between the two groups (P=0.023). There was no statistical difference in recurrence of infection, perivalvular leakage and reoperation between the two groups. Composite endpoint-free survival rate at 1, 5, 10, 20 years after surgery was 100.0%, 97.6%, 92.9%, 92.9% for MVP, and 91.3%, 79.6%, 75.8%, 51.0% for MVR with a statistical difference (P=0.006). Conclusion MVP is associated with better outcomes than MVR in the patients with NVE; generalizing MVP technique in the patients with NVE is needed.
Objective To investigate the choleenterostomy type and the longterm results in treatment of benign diseases of biliary tract. MethodsA total of 614 cases of choleenterostomy from January 1981 to December 2000 were followed up and analysed. The original diseases: 321 were original hepatolithiasis and/or bileduct stricture (52.3%)， 106 congenital cyst of common bile duct (17.3%), 151 iatrogenic bile duct injury (24.6%) and others 36 cases (5.9%). Choledochoduodenostomy was performed in 89 cases and choledochojejunostomy in 525 cases. Five hundred and twentyfour cases have been followed up for 1 to 20 years. The rate of followup was 87.9%. ResultsIn 84.5% of the cases, excellent or good longterm results were achieved. Reoperation rate were 49.4% in cases of choledochoduodenostomy or cystoduodenostomy, 14.2% in sideside (cyst) cholangiojejunostomy and 4.4% in endside cholangiojejunostomy, respectively. Conclusion The choledochoduodenostomy should be abolished. The endside cholangiojejunostomy shoud be the best choice when it is needed to perform choledochojejunostomy in benign bile duct diseases and can promise a satisfactory longterm result.
The surgical treatment of acute aortic dissection is difficult, and the mortality is associated with anastomosis site complications. Therefore, it is essential to make sure the end-to-end anastomosis safe and avoid bleeding. The methods of anastomosis include: direct anastomosis, adventitial inversion technique and sandwich technique. The latter two methods are both effective in hemostasis and reducing the postoperative complications. According to the recent literatures, the adventitial inversion technique may facilitate thrombotic closure of the false lumen in acute type A aortic dissection management and increase the long-term survival of the patients. This review introduces 2 modified methods of anastomosis as well, and summarizes clinical outcomes of different end-to-end anastomotic methods for surgical treatment of acute Stanford type A aortic dissection, in order to recommend the most proper method of end-to-end anastomosis.
ObjectiveTo analyze the long-term efficacy and its influencing factors in the treatment of the permanent atrial fibrillation(AF) using monopolar radiofrequency ablation during concomitant cardiac valve replacement surgery with rheumatic heart disease. MethodsClinical data of the 116 patients with rheumatic heart disease and permanent AF who underwent modified maze procedure using monopolar radiofrequency ablation and concomitant cardiac valve replacement in the affiliated hospital of Qingdao university from October 2004 to December 2010 were collected and retrospectively analyzed, including 43 males and 73 females with their age of 50.5±7.5 years. Electrocardiogram (ECG) with 12-lead and echocardiography data, as well as the related complications, cardiac function and life quality were collected at the time of the immediately after the operation, discharge from hospital, 3 months, 6 months, 1 year postoperatively and every year after the operation. Patients were divided into eliminating group of AF (including sinus rhythm and nodal rhythm) and AF group according to the results of the ECG at the time of the ending follow-up. In the eliminating group of AF, there were 52 patients (16 males, 36 females) with their age of 48.4±7.3 years, and in the AF group, there were 50 patients (22 males, 28 females) with their age of 51.9±7.1 years. Analyzed the difference of the related factors between the two groups using statistical methods and tried to find the factors affecting the long-term clinical efficacy of the operation. ResultsThree patients died in hospital (one died of the hemolysis, acute renal insufficiency and hyperkalemia. One died of the multiple organ dysfunction syndrome caused by the acute renal insufficiency. And the other one died of the multiple organ dysfunction syndrome caused by the repetitive ventricular tachycardia and ventricular fibrillation on the day of the automatic discharge). Three patients died during the follow-up (one died after the reoperation because of the perivalvular leakage in other hospital, and the causes of death in the two others could not be catched). One patient occurred cerebral embolism, and the other one occurred cerebral hemorrhage in the af group during the follow-up. There was statistical significance between two group at the aspects of age, preoperative AF duration, preoperative left atrium diameter, time of the cardiopulmonary bypass and time of the cross-clamp ascending aorta. In multivariate analysis, age and preoperative left atrium diameter are risk factors affecting the long-term efficacy. ConclusionThe treatment of the permanent atrial fibrillation using monopolar radiofrequency ablation concomitant cardiac valve replacement with rheumatic heart disease is effective and has good long-term efficacy. The factors of affecting the long-term clinical efficacy are the patient's age and the diameter of left atrium.
Objective To explore the risk factors for long-term death of patients with acute myocardial infarction (AMI) and reduced left ventricular ejection fraction (LVEF), and develop and validate a prediction model for long-term death. Methods This retrospective cohort study included 1013 patients diagnosed with AMI and reduced LVEF in West China Hospital of Sichuan University between January 2010 and June 2019. Using the RAND function of Excel software, patients were randomly divided into three groups, two of which were combined for the purpose of establishing the model, and the third group was used for validation of the model. The endpoint of the study was all-cause mortality, and the follow-up was until January 20th, 2021. Cox proportional hazard model was used to evaluate the risk factors affecting the long-term death, and then a prediction model based on those risk factors was established and validated. Results During a median follow-up of 1377 days, 296 patients died. Multivariate Cox regression analysis showed that age≥65 years [hazard ratio (HR)=1.842, 95% confidence interval (CI) (1.067, 3.179), P=0.028], Killip class≥Ⅲ[HR=1.941, 95%CI (1.188, 3.170), P=0.008], N-terminal pro-brain natriuretic peptide≥5598 pg/mL [HR=2.122, 95%CI (1.228, 3.665), P=0.007], no percutaneous coronary intervention [HR=2.181, 95%CI (1.351, 3.524), P=0.001], no use of statins [HR=2.441, 95%CI (1.338, 4.454), P=0.004], and no use of β-blockers [HR=1.671, 95%CI (1.026, 2.720), P=0.039] were independent risk factors for long-term death. The prediction model was established and patients were divided into three risk groups according to the total score, namely low-risk group (0-2), medium-risk group (4-6), and high-risk group (8-12). The results of receiver operating characteristic curve [area under curve (AUC)=0.724, 95%CI (0.680, 0.767), P<0.001], Hosmer-Lemeshow test (P=0.108), and Kaplan-Meier survival curve (P<0.001) showed that the prediction model had an efficient prediction ability, and a strong ability in discriminating different groups. The model was also shown to be valid in the validation group [AUC=0.758, 95%CI (0.703, 0.813), P<0.001]. Conclusions In patients with AMI and reduced LVEF, age≥65 years, Killip class≥Ⅲ, N-terminal pro-brain natriuretic peptide≥5598 pg/mL, no percutaneous coronary intervention, no use of statins, and no use of β-blockers are independent risk factors for long-term death. The developed risk prediction model based on these risk factors has a strong prediction ability.
Abstract: Objective To evaluate the longterm results of surgical treatment of tetralogy of Fallot (TOF) in adults and discuss the perioperative treatment skills. Methods From January 2000 to March 2008, 149 patients older than 14 years with tetralogy of Fallot received surgical treatment in Changhai Hospital. Among the patients, there were 78 males and 71 females with ages ranged from 14 years to 53 years and the average age was 26.3 years. Twenty patients had previous pulmonary arterial shunts before radical treatment. A total of 129 patients underwent primary radical treatment. Thirtyeight patients received a right ventricular outflow tract patch, 107 patients had transannular patch, and 4 patients had homograft aorta with valves. Results Hospital mortality was 4.0%(6/149). Four patients died of low cardiac output syndrome (LCOS), and multiple organ failure, and 2 patients died of acute renal failure. The postoperative complications included pleural effusion in 11 patients, pulmonary edema in 10 patients, severe LCOS in 9 patients, severe cardiac arrhythmia in 7 patients, reoperation for excessive bleeding in 7 patients, reintubation in 6 patients, and residual ventricular septal defect (VSD) in 5 patients (two of them had reoperation for residual VSD repair and 2 received transcatheter closure of VSD). One hundred and thirtyfour patients were followed up for 3 to 102 months (47.2±28.6 months) with a followup rate of 93.7%(134/143). Late death occurred in 2 patients, one of whom died of secondary infective endocarditis and the other had a sudden death 29 months after operation. During the followup, one patient had residual VSD (2 mm), but had a normal life. The peak systolic right ventricletopulmonary artery pressure gradient exceeded 40 mmHg in 4 patients. Two patients had severe pulmonary regurgitation. A total of 132 patients survived and had an improved life. One hundred and twentyone patients had class Ⅰ heart function (NYHA), and 11 patients in class Ⅱ. Conclusion The pathophysiologic conditions of the patients with tetralogy of Fallot in adults are very complicated due to longterm right ventricle outlet stricture and chronic hypoxia. Preoperative evaluations and postoperative treatment of complications are necessary. The systemicpulmonary arterial shunts should be performed when hypotrophy of the pulmonary arteries or left ventricles exists. Repair of tetralogy of Fallot in adults has acceptable morbidity and mortality rates with goodlongterm outcomes.
ObjectiveTo evaluate the long-term effectiveness of patients received surgical treatment under the guidance of “West China Classification” of desmoid-type fibromatosis (DTF) in the shoulder girdle.MethodsThe clinical data of 32 patients with DTF in the shoulder girdle admitted between June 2003 and December 2016 were retrospectively analyzed, including 14 males and 18 females, aged 14-56 years with an average age of 36.8 years. The maximum diameter of the tumor was 7-19 cm, with an average of 11.1 cm. According to the “West China Classification” of DTF in the shoulder girdle, there were 4 cases of region Ⅰ, 3 cases of region Ⅱ, 6 cases of region Ⅲ, 3 cases of region Ⅳ, 5 cases of regions Ⅰ+Ⅱ, 5 cases of regions Ⅱ+Ⅲ, and 6 cases of regions Ⅰ+Ⅱ+Ⅲ. In addition, the involvement of blood vessels and nerves was also taken into consideration for choosing a surgical approach. Finally, 12 cases were operated via anteroposterior approach (group A), 14 via posterior approach (group B), and 6 via combined anterior-posterior approach (group C). The 1993 Musculoskeletal Tumor Society (MSTS93) score (including pain, limb function, satisfaction, hand position, hand flexibility, and lifting ability), Japanese Orthopedic Association (JOA) score, range of motion (ROM) of shoulder joint (including flexion, extension, abduction, and adduction), and complications of patients in the 3 groups were recorded and compared.ResultsAll the 32 patients were followed up 30-190 months, with an average of 94.6 months. At last follow-up, complications occurred in 5 cases (15.6%), including 2 cases (16.6%) in group A, 2 (14.3%) in group B, and 1 (16.6%) in group C. There was no significant difference in the incidence of complications among the 3 groups (P=1.000). Tumor recurrence occurred in 5 (15.6%) cases, including 1 (8.3%) case in group A, 2 (14.3%) in group B, and 1 (16.6%) in group C. No significant difference was found in the recurrence rate among the 3 groups (P=1.000). At last follow-up, MSTS93 score of pain, limb function, satisfaction, hand flexibility, and hand position in groups A and B were significantly better than those in group C (P<0.05), even though no significant difference existed between group A and group B (P>0.05). The lifting ability score in group C was significantly lower than in group A (P<0.05), and no significant difference was found between other groups (P>0.05). The JOA score and flexion, extension, abduction, and adduction activities of shoulder in groups A and B were significantly better than those in group C (P<0.05). The extension activity in group A was significantly better than that in group B (P<0.05), the flexion activity in group B was significantly better than that in group A (P<0.05). There was no significant difference in other indexes between groups A and B (P>0.05).ConclusionTaking a rational approach to fully expose and completely remove the tumor is the key point of surgical treatment for patients with DTF in the shoulder girdle. At the same time, preservation of vital structures and reconstruction of soft tissues should also be taken into consideration. Overall, surgical treatment under the guidance of “West China Classification” of DTF in the shoulder girdle has achieved satisfactory long-term effectiveness.
ObjectiveTo explore the role of chest wall arteriovenous graft (CWAVG) for establishing hemodialysis access in patients with end-stage renal disease.MethodsA retrospective analysis was made on the clinical data of 12 patients with end-stage renal disease who underwent CWAVG for establishing hemodialysis access between January 2014 and June 2015. There were 3 males and 9 females with an average age of 63.6 years (range, 54-82 years). The renal disease causes were chronic glomerulonephritis in 2 cases, hypertensive renal damage in 4 cases, diabetic nephropathy in 1 case, both kidney resection because of urinary tract tumors in 3 cases, and causes unknown in 2 cases. Hemodialysis time ranged from 1 to 144 months, with an average of 38.4 months. The 12 patients all underwent 1-14 times (mean, 4.2 times) anterior pathway failure in CWAVG, all of which were caused by repeated occlusion of dialysis pathway or poor vascular condition of upper extremity, resulting in the exhaustion of vascular pathway in upper extremity.ResultsAll patients were followed up 30-48 months (mean, 35.4 months). Two patients died, including 1 case of digestive tract hemorrhage, 1 case of heart failure. The other 10 CWAVGs were functionally useful for hemodialysis access about 6 weeks after operations. The primary patency rates at 6, 12, 18, 24, and 30 months were 83.3%, 75.0%, 33.3%, 33.3%, and 16.7%, respectively, and the cumulative patency rates at 6, 12, 18, 24, and 30 months were 83.3%, 75.0%, 50.0%, 33.3%, and 16.7%, respectively. Among 8 cases of CWAVG dysfunction, 6 cases had thrombosis, 1 case had seroma, and 1 case had vertebral artery stealing. Among them, 4 patients underwent hemodialysis using tunneled-cuffed catheter, 3 patients using fistula or graft on other limbs, and 1 patient was not treated with hemodialysis.ConclusionAlthough the long-term patency rate of CWAVG is yet to be further increased by improvement of treatment strategies, but it is still a supplementary option for end-stage renal disease patients with inadequate upper extremity venous access sites.
