Objective To explore the indications for liver transplantation among patients with hepatolithiasis. Methods Data from 1431 consecutive patients with hepatolithiasis who underwent surgical treatment from January 2000 to December 2006 were retrospectively collected for analysis. Surgical procedures included T-tube insertion combined with intraoperative cholangioscopic removal of intrahepatic stones, hepatectomy, cholangiojejunostomy, and liver transplantation. Results Nine hundred and sixty-one patients who had a stone located in the left or right intrahepatic duct underwent hepatectomy or T-tube insertion combined with intraoperative cholangioscopic removal of intrahepatic stones. The rate of residual stones was 7.5% (72/961). Four hundred and seventy patients who had a stone located in the bilateral intrahepatic ducts underwent surgical procedures other than liver transplantation; the rate of residual stones was 21.7% (102/470). Only 15 patients with hepatolithiasis underwent liver transplantation; they all survived. According to the degree of biliary cirrhosis, recipients were divided into 2 groups: a group with biliary decompensated cirrhosis (n=7), or group with biliary compensated cirrhosis or noncirrhosis group (n=8). There were significant differences in operative times, transfusion volumes and blood losses between 2 groups (P＜0.05). In the first group, 6 of 7 patients experienced surgical complications, and in the second, 8 recipients recovered smoothly with no complications. Health status, disability and psychological wellness of all recipients (n=15) were significantly improved in 1 year after transplantation as compared with pretransplantation (P＜0.05). Conclusion Liver transplantation is a possible method to address hepatolithiasis and secondary decompensated biliary cirrhosis or difficult to remove, diffusely distributed intrahepatic duct stones unavailable by hepatectomy, cholangiojejunostomy, and choledochoscopy.
Objective To summarize the probability of pulmonary embolism （PE） induced by lower extremity deep venous thrombosis （DVT） and investigate the role of vena cava filter （VCF） in preventing from PE. Methods The clinical data of 1 058 patients with lower extremity DVT from January 2005 to January 2012 were analyzed retrospectively. Results The PE rate was 3.21% （34/1 058） and the death rate was 1.42% （15/1 058） in 1 058 patients with lower extremity DVT. The VCF was implanted in 171 of 1 058 patients. The VCFs of 151 patients were implanted from femoral vein， 20 patients were implanted from jugular vein. The PE rates were 3.61% （32/887） and 1.17% （2/171） and the death rates were 1.69% （15/887） and 0 （0/171） in patients without VCF and with VCF， respectively. Both of them occurred in the first ten days. PE could keep as long as 35 d. The PE rate and death rate in the patients without VCF were significantly higher than those in the patients with VCF （P＜0.01）. The PE rates and death rates in both lower extremities DVT were higher than those in patients with the right and left ones （P＜0.05）， which in the right lower extremity were higher than those in the left one （P＜0.05）. The PE rate and death rate in the patients with lower extremity DVT combined with vena cava thrombosis were significantly higher than those in the patients with central type （P＜0.05）， which in the central type were significantly higher than those in the peripheral type （P＜0.05）， there were no significant differences between peripheral type and mixed pattern. The follow-up time was from 1 month to 7 years with （39±19） months， the patency rate of VCF was 98.7%. There were no filter migration， declination， and failure of expansion. Conclusions VCF can prevent from PE effectively， but the indications must be controlled.
Transcatheter aortic valve replacement (TAVR) is an emerging alternative for the treatment of aortic stenosis (AS). Evidence from clinical trials sprang up continuously, and guidelines have listed TAVR as an alternative for part of AS patients. Although old guidelines only recommended TAVR for surgical high-risk or in-operable AS patients, the latest guidelines have expanded its indications enormously. Moreover, there are ongoing TAVR studies on low-risk patients, asymptomatic patients, pure aortic regurgitation patients, bicuspid aortic valve patients,etc. It is believed that the indication of TAVR will continue to expand. More and more patients will benefit from TAVR in the foreseeable future.
Objective To explore the treatment of the malunited fracture of the tibial plateau. Methods From June 2000 to June 2005, reconstruction was performed on 29 patients (18 males, 11 females; age, 1943 years, average, 31.6 years) with the malunited fracture of the tibial plateau. The injury duration ranged from 2.5 months to 2 years, averaged 9.7 months. After the injury, the plasterexternal fixation was performed on 8 patients and operation was performed on the other 21 patients. The operation was involved in the use of screws in 11 patients, anatomic plates, Golf plates and allotype plates in 8 patients, external fixation braces in 2 patients. A complicating injury to the anterior cruciate ligament (ACL) was found in 4 patients, an injury to the posterior cruciate ligament(PCL) in 2 patients, an injury to both ACL and PCL in 1 patient, and an injury to the meniscus in 6 patients. Reestablishment was performed on 19 patients, high tibial osteotomy on 7 patients, and osteotomy of the half tibial metaphysis on3 patients. Results Base on the followup for 8 months to 3 years(average, 13.6 months), the comprehensively scoring assessment showed that an excellent result was achieved in 8 patients, good in 15, fair in 4, and poor in 1, with an excellent and good rate of 82.1%, according to the Hohl knee joint function assessment on the pain, active movement, motion range, stability, and selfassessment. ConclusionFor the reconstruction of the malunited fracture of the tibial plateau, the satisfactory therapeutic effectiveness can only be achieved if the proper indications are identified and the suitable operative methods are adopted. The total knee replacement is only applicable to the elderly patient, and for the young patient, the reconstruction should be performed.
ObjectiveTo summarize the procedures of the shoulder arthroplasty and the evolution of the shoulder prosthesis, and to discuss the indications and contraindications of the several common shoulder arthroplastis. MethodsThe related literature on shoulder arthroplasty was extensively reviewed, summarized, and analyzed. ResultsAt present, shoulder arthroplasties can be classified into shoulder hemiarthroplasty, total shoulder arthroplasty, resurfacing shoulder arthroplasty, stemless shoulder arthroplasty, and reserve shoulder arthroplasty, etc. Each type of the prosthesis has several special indications and contraindications. Mostly, the shoulder arthroplasties achieved the satisfied results, such as pain-relief and restoration of the elevation and adduction of shoulder. The survival rate of the most shoulder prostheses may reach 10 years or more. ConclusionMost shoulder arthroplasties are effective and satisfied to treat the shoulder traumas and diseases in pain-free and functional restoration of shoulders.
ObjectiveTo discussion the indications and contradictions of associating liver partition and potal vein ligation for staged hepatectomy (ALPPS) for primary hepatocellular carcinoma patients. MethodsThe date of 15 patients underwent the ALPPS in West China Hospital between Augst, 2014 and March, 2015 were retrospectively analyzed. The efficacy of the treatment was evaluated by blood test, the volume of residual liver growth, and postoperative follow-up. ResultsFourteen cases underwent the complete ALPPS, 1 case lost because it couldn't match the standard for the second step. The median increase in the future liver remnant(FLR) volume was 205.5 cm3[(-7.92)-270.6 cm3] and the median rate of FLR increase was 56.5%[(-1.89%)-134.74%]. One case died in the perioperative period for the liver failure, 2 cases was found recurrence or metastasis and died in 3 and 4 months after operation, respectively. One case's AFP was found rising but no iconography evidence for recurrence. One case with tumor survival about 4 moths. The remaining 10 patients were alive without recurrence and metastasis. ConclusionsALPPS is a feasible strategy in patients with cirrhosis and can improve the resectability of hepatocellular carcinoma to provide a chance of a cure to those who would not otherwise be able to receive surgery. And we put out an indications and contradictions for ALPPS tentatively.
ObjectiveTo investigate the development and clinical application of the reverse total shoulder arthroplasty. MethodsThe relative publications on reverse total shoulder arthroplasties were extensively reviewed and analyzed. ResultsReverse total shoulder arthroplasty has extensive indications, especially for pseudoparalysis caused by irrepairable rotator cuff tears with forward or upper shift of the humeral head and intact function of deltoid. The clinical research results indicate that the short-term results are satisfactory, but there are some special complications, such as scapular nothching, instability and limities of internal and external rotation. While performing this kind of operation, the selection of the approach, the determination of the prosthetic rotation center should be considered well, and the bone graft should be paid attention to when the bony defect of the glenoid and proximal humerus exists. ConclusionThe using time of the reverse total shoulder arthroplasty is short, so the long-term results should be observed. The development of computer assisted technique is hopeful to be improve the results of the reverse total shoulder arthroplasty.
With the development of surgical technology and the need of clinical, transesophageal echocardiography is more and more favored by clinicians. Although the transesophageal echocardiography has developed more than 20 years, yet it has not been widely used in operation at present in domestic. In addition, its application in surgery of children is more rare. It has been confirmed that intraoperative use of transesophageal echocardiography has good safety and wide range of application. We will summarize indications, complications, and the progress of the current technology from the scope of transesophageal echocardiography in pediatric surgery.
ObjectiveTo summarize the clinical experience on primary suture after common bile duct exploration and to investigate its clinical indications and curative effects. MethodsThe clinical data of 137 patients underwent primary closure of common bile duct between February 2006 and June 2010 were analyzed retrospectively. ResultsAll operations were successful. The operative time ranged from 65-213 min (mean 129 min) and the blood loss ranged from 50-350 ml with an average of 148 ml. One hundred and twenty-four patients (90.5%) were discharged from hospital without complications within 7 d after operation. Postoperative bile leakage occurred in 13 patients (9.5%) consisted of 10 early stage cases (18.5%, 10/54) and 3 later stage cases (3.6%, 3/83), which were discharged with improvement by conservative treatment within 3 weeks after operation. Totally 113 patients (82.5%) were followed up for 2-54 months with a median time of 14 months, no residual or retained stone and biliary duct stricture occurred. ConclusionOnly with the strict indication and proficient surgical technology, primary suture after common bile duct exploration is a safe and effective way to choledocholithiasis.
Transcatheter aortic valve replacement (TAVR) developed rapidly since firstly introduced to clinical practice in 2002. In 2015, Experts Consensus for Transeatheter Aortic Valve Replacement (abbreviated as the Consensus) helped TAVR develop normatively and safely in China. This article interpreted the Consensus in combination of new evolutions of TAVR field: first, the indications of TAVR expand from inoperative and high risk patients to the intermediate risk patients; second, although the Consensus recommended pre-dilation with balloon of modest size, the necessity of pre-dilation is under debate; third, the Consensus pointed out main complications of TAVR, and the main strategies to avoid complications are careful pre-procedural analysis and development of new device; fourth, our experts had made outstanding contribution to TAVR in the treatment of patients with bicuspid aortic valve, which still has many problems to be solved urgently.
