Objective To evaluate long-term outcomes of surgical closure of atrial septal defect (ASD) and combined surgical radiofrequency ablation for atrial fibrillation (AF). Methods A total of consecutive 15 patients with ASD undergoing surgical closure of ASD and combined surgical radiofrequency ablation in our department between March 2003 and April 2015. There were 7 males and 8 females at an average age of 47.1±10.8 years ranging from 16 to 62 years. Retrospective analysis and follow-up were performed to evaluate long-term success rate freedom from AF after surgery. Results All patients recovered and discharged, and no patient suffered death or stroke. The duration of follow-up was from 3 to 136 months for all patients. Success rate freedom from AF at 1, 3, 5 and 10 years was 81.3%, 75.0%, 68.8% and 61.1%, respectively. During follow-up, there was no death or stroke. One patient required permanent pacemaker implantation. Conclusion Concomitant surgical closure of ASD and biatrial radiofrequency ablation is safe and effetive with better long-term outcomes. It is necessary to perform the two procedures together for ASD patients.
ObjectiveTo evaluate long-term radiographic and clinical effectiveness of total cervical disc replacement (TDR) with Prodisc-C prosthesis at a minimum of 10 years follow-up.MethodsThe clinical data of 118 patients with cervical disc degeneration disease (CDDD) treated with TDR by using Prodisc-C prosthesis between December 2005 and April 2008 were retrospectively analyzed. There were 66 males and 52 females, with the age of 25-62 years (mean, 46.8 years). There were 38 cases of cervical spondylotic radiculopathy, 28 cases of cervical spondylotic myelopathy, and 52 cases of mixed cervical spondylotic myelopathy. The operative segments were C3-7, including 90 cases of single segment, 20 cases of continuous double segments, and 8 cases of continuous three segments. A total of 154 Prodisc-C prostheses were used during the operation. The clinical effectiveness was evaluated by pain visual analogue scale (VAS) score, neck disability index (NDI), Japanese Orthopaedic Association (JOA) score, and Odom grade before and after operation. Imaging evaluation indicators included range of motion (ROM), sagittal lordosis angle, intervertebral disc height (IDH), and prosthesis displacement, subsidence, loosening, locking, and heterotopic ossification (HO), adjacent segment degeneration (ASD), and other complications. Patients were grouped according to whether HO or ASD occurred or not, the ROM of surgical segment was compared.ResultsAll patients were followed up 121-150 months (mean, 135.8 months). No revision operation was performed during the follow-up period. The VAS, NDI, JOA scores and Odom grades were significantly improved at 1 week after operation and last follow-up when compared with preoperative ones (P<0.05); VAS and NDI scores were further improved at last follow-up than those at 1 week after operation (P<0.05); there was no significant difference in JOA scores and improvement rates between at 1 week after operation and at last follow-up (P>0.05). The ROM of the whole cervical spine and the operative segment decreased at 1 week and 10 years after operation when compared with preoperative ones (P<0.05), but there was no significant difference in the other time points (P>0.05); there was no significant difference in the ROM between the upper adjacent segment (UAS) and the lower adjacent segment (LAS) at each time point after operation (P>0.05). There was no significant difference in sagittal lordosis angle of cervical spine before and after operation (P>0.05); the sagittal lordosis angle of operative segment increased significantly at 1 week, 6 months, 1 year, and 2 years after operation (P<0.05). The IDH of operative segment was significantly improved at each time point after operation (P<0.05), but there was no significant difference in IDH between UAS and LAS at each time point after operation (P>0.05). No prosthesis displacement, subsidence, or loosening occurred at each time point after operation. There was no significant difference of the prosthetic displacement and subsidence distance between all time points after 6 months after operation (P>0.05). At last follow-up, the incidence of prosthetic locking/fusion was 10.4%, showing no significant difference when compared with 6 months (1.9%) (P<0.05). The incidence of upper ASD and lower ASD was 1.3% and 2.6% respectively at 1 week after operation. The incidence of upper ASD and lower ASD increased gradually with time prolonging, and there were significant differences between different time points (P<0.05). The ROM of operative segment in ASD group was lower than that in non-ASD group at each time point after operation, but there was no significant difference (P>0.05). HO appeared in 58.4% of the segments at 6 months after operation, and the incidence of HO increased significantly with time, which was significantly different from that at 6 months after operation (P<0.05). The ROM of operative segments in HO group was significantly lower than that in non-HO group at 6 months, 2 years, 5 years, and 10 years after operation (P<0.05).ConclusionTDR has little effect on adjacent segments, although there are some imaging complications, it has no significant effect on the improvement of overall clinical effectiveness. Prodisc-C prosthesis can provide long-term, safe, and definite clinical effectiveness in the treatment of CDDD.
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.
Objective To retrospectively analyze the long-term effectiveness of percutaneous laser disc decompression (PLDD) in treatment of cervical spondylosis. Methods Between March 2003 and June 2005, 156 patients with cervical spondylosis were treated with PLDD. There were 74 males and 82 females with an average age of 55.4 years (range, 31-74 years). The disease duration varied from 2 months to 15 years. Fifty-nine patients were classified as cervical spondyloticradiculopathy, 48 as vertebral-artery-type cervical spondylosis, 19 as cervical spondylotic myelopathy, and 30 as mixed type spondylosis. The lesions were located at the levels of C3,4 in 32 discs, C4,5 in 66 discs, C5,6 in 89 discs, and C6,7 in 69 discs, and including 71 one-leve lesion and 85 multi-level lesions. All cases were followed up to study the long-term effectiveness and correlative factors. Results A total of 117 (75%) patients’ symptoms were l ightened or eased up immediately after operation. Discitis occurred in 1 case at 3 days after operation and was cured after 3 weeks of antibiotic use. All patients were followed up 5 years to 7 years and 3 months (5 years and 6 months on average). According to Macnab criteria, the long-term effectiveness was excellent in 60 cases (38.46%), good in 65 cases (41.67%), fair in 19 cases (12.18%), and poor in 12 cases (7.69%); the excellent and good rate was 80.13%. No significant difference was observed in the wedge angels and displacements of the intervertebral discs between before and after operations (P gt; 0.05). Multiple-factors logistic regression showed that the disease duration and patient’s age had obvious relationship with the effectiveness of treatment (P lt; 0.05), while the type of cervical spondylosis, disc protrusion degree, mild cervical instabil ity, and lesion scope had no correlation with the effectiveness of treatment (P gt; 0.05). Conclusion PLDD is safe and effective in treatment of cervical spondylosis with less compl ication. There is no impact on the stabil ity in cervical spinal constructs. The disease duration and patient’s age have obvious impact on the long-term effectiveness of treatment. The type of cervical spondylosis, disc protrusion degree, cervical instabil ity, and lesion scope are not the correlative factors.
ObjectiveTo evaluate the long-term effectiveness of lunate excision and vascularized capitate osteotomy transposition for advanced Kienböck's disease. MethodsBetween June 2004 and January 2008,16 patients with Kienböck disease in Lichtman stages ⅢB-IV were treated with lunate excision and vascularized capitate osteotomy transposition.There were 10 males and 6 females at the age of 27-59 years (mean,38.8 years).The disease was caused by trauma in 10 cases,and unknown reason in 6 cases.The main clinical symptoms were pain and limited activity of the wrist joint,and the disease duration was 5-32 months (mean,26.5 months).The carpal height index was 0.88±0.05; the radioscaphoid angle was (63.8±9.1)°.The visual analogue scale (VAS) score,range of motion (ROM),grip strength,Evans score,and radiographic changes were used to assess the effectiveness during follow-up. ResultsAll patients obtained healing of incision by first intention and were followed up 5 years and 4 months to 9 years (mean,5.8 years).VAS score was 2.0±1.5 at the final follow-up.The ROM of the flexion and extension of the wrist joint at the affected side were significantly less than those at the normal side (P<0.05).However,no significant difference was found in the grip strength and Evans score between the affected side and normal side (t=-0.997,P=0.327; t=-1.852,P=0.077).Postoperative radiographs showed that the carpal height index was 0.94±0.03,and the radioscaphoid angle was (48.4±4.8)°,which were improved significantly when compared with preoperative ones (t=-3.927,P=0.000; t=5.987,P=0.000).Osteophyte at the dorsal side of the radius and scaphoid rotation occurred in 6 cases and 2 cases,respectively. ConclusionLunate excision and vascularized capitate osteotomy transposition is a reliable method for advanced Kienböck's disease,with favorable improvement in wrist pain and grip strength for long-term follow-up.
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.
ObjectiveTo analyze the surgical efficacy and influencing factors of myasthenia gravis (MG) patients with thymic atrophy after thymectomy. MethodsThe clinical data of MG patients with thymic atrophy undergoing thymectomy between October 2014 and May 2018 in Daping Hospital of Army Medical University and Shijiazhuang People Hospital were retrospectively analyzed. ResultsA total of 71 patients were collected, including 40 males and 31 females with a mean age of 45.17±12.42 years. All patients received the surgery successfully. After the surgery, 20 (28.17%) patients were stable remission, 12 (16.90%) patients were minimal manifestation status,19 (26.76%) patients were improved, 5 (7.04%) patients showed no change, 3 (4.23%) patients were worsened, 10 (14.08%) patients were exacerbated and 2 (2.82%) patients were dead. Multivariate logistic regression analysis showed that the preoperative illness duration (OR=4.61, 95%CI 1.13-18.85, P=0.03), and postoperative pyridostigmine combined with immunosuppressive (OR=0.12, 95%CI 0.03-0.45, P=0.00) were independent risk factors for long-term efficacy of thymectomy for MG patients with thymic atrophy. ConclusionEarly surgery after diagnosis of MG and postoperative pyridostigmine combined with immunosuppressive treatment is beneficial to the prognosis of MG patients with thymic atrophy.
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 investigate the long-term efficacy and the influencing factors of thymectomy for thymoma patients associated with myasthenia gravis. MethodsWe retrospectively analyzed the clinical and follow-up data of 126 thymoma patients associated with myasthenia gravis underwent extended thymectomy from June 2002 to December 2015 in our hospital. There were 26 males and 37 females at the mean age of 54.51±12.62 years. We built up survival analysis model to analyze the effect of those following factors on postoperative result:sex, the age when operated, the preoperative course of disease, the condition of associating with other diseases, history of critical illness, steroid administration time before operation, Osserman classification, Masaoka staging, WHO pathological type, surgical approach, tumor size and so on. Result The average follow-up time was 35(5-96) months. During follow-up period, 12 patients (19%) achieved complete remission, 39 patients (62%) achieved partial remission, 7 patients (11%) kept stable, 5 patients (8%) deteriorated and the total effective rate was 81%. The result of log-rank analysis showed that the preoperative course of disease (P=0.027), history of critical illness on myasthenia gravis (P=0.035) and Osserman classification (P=0.018) were related to incomplete remission, whlie the result of Cox regression analysis showed that the preoperative course of disease (P=0.001) and Osserman classification (P=0.012) were the independent risk factors for incomplete remission. ConclusionExtended thymectomy is an effective treatment for thymoma patients associated with myasthenia gravis, but the symptom of those patients whose preoperative course of disease are more than 12 months or Osserman classification is at ⅡB, Ⅲ and Ⅳ type of Osserman classification have poor effect after operation.
Objective To assess the medium- and long-term effectiveness of selective posterior rhizotomy (SPR) for spastic cerebral palsy. Methods A retrospective analysis was made on 27 patients with spastic cerebral palsy undergoing SPR between January 1997 and January 2008, whose data were complete with more than 5 years follow-up. There were 14 males and 13 females with an average age of 10.1 years (range, 4-19 years). All patients had simple spastic cerebral palsy, including 17 cases of bilateral spastic palsy and 10 cases of unilateral spastic palsy. The muscle strength, muscle tone, ambulatory function, the sharp foot and crossing-feet, knee jerk, ankle clonus, and Babinski’s sign were evaluated before and after operation. Results All the patients were followed up 5-16 years (mean, 9.6 years). No obvious limitation of lumbar flexion, extension and lateral flexion, spondylolisthesis, kyphosis, and other deformities occurred. At last follow-up, the muscle strength of hip extensors, hip flexors, and knee extensors were significantly increased when compared with preoperative ones (P lt; 0.05); but no significant difference was found in the muscle strength of hip abductors, hip adductors, knee flexors, plantar extensors, and plantar flexors (P gt; 0.05). Abnormal increased muscle tone of hip flexors, hip adductors, knee flexors, and plantar flexors was declined in different degrees in all patients, showing significant differences when compared with preoperative ones (P lt; 0.05); but no significant difference was found in hip extensors, hip abductors, knee extensors, and plantar extensors (P gt; 0.05). At last follow-up, the status of toe steps and crossing-feet disappeared without recurrence for a long time. Sthenic knee jerk was eliminated, but there were several patients also keeping the active knee jerk, showing significant difference when compared with preoperative ones (Z= — 7.404, P=0.000). The results of Babinski’s sign were negative in 31 sides and positive in 13 sides, showing significant difference when compared with preoperative ones (Z= — 6.897, P=0.000). No sharp foot or crossing-feet was observed. And ambulation ability was significantly improved after operation (Z= — 4.111, P=0.000). Conclusion SPR is very effective in decreasing the muscle tone and improving the motor function without recurrence in long-term.
