Objective
To investigate the clinical value of " O”continuous biliary-enteric anastomosis combined with percutaneous transhepatic cholangial drainage (PTCD) in pancreaticoduodenectomy (PD).
Methods
The clinical data of 35 patients with PD who were admitted to Xinyang Central Hospital from June 2015 to June 2017 were retrospectively analyzed.
Results
All patients completed the " O” continuous biliary-enteric anastomosis combined with PTCD without perioperative death. ① The preoperative indwelling time of PTCD tube was (13.24±3.39) d, total bilirubin (TBIL) was (363.67±12.26) μmol/L on admission and (155.59±17.63) μmol/L on preoperative after PTCD, respectively. ② The operative time was (231.46±18.69) min, the intraoperative blood loss was (158.30±31.33) mL, the diameter of the hepatic ductal segment was (1.3±0.2) cm, and the duration of the " O” continuous biliary-enteric anastomosis was (7.31±1.52) min. ③ After surgery, the indwelling time of PTCD tube was (8.13±1.49) d, the hospitalization time was (27.31±5.49) d. Biliary leakage occurred in 1 case, pancreatic fistula occurred in 5 cases (3 cases of biochemical sputum and 2 cases of B-stage pancreatic fistula), abdominal infection occurred in 2 cases, pneumonia occurred in 3 cases, wound infection occurred in 2 cases. No postoperative biliary-enteric anastomosis stenosis, biliary tract infection, and intra-abdominal hemorrhage occurred. There was no laparotomy patients in this group and all patients were discharged. ④ All patients were followed-up for 180 days after surgery. No death, bile leakage, biliary-enteric anastomotic stenosis, biliary tract infection, pancreatic fistula, gastro-intestinal leakage, and abdominal infection occurred. One case of delayed gastric emptying and 2 cases of alkaline reflux gastritis were cured after outpatient treatment.
Conclusions
The preoperative PTCD can improve the preoperative liver function and increase the security of PD. " O” continuous biliary-enteric anastomosis is simple, safe, feasible, and has the function of preventing biliary-enteric anastomosis stenosis. For severe jaundice patients with blood TBIL >170 μmol/L, the " O” continuous biliary-enteric anastomosis combined with PTCD is an alternative surgical procedure for PD.
Objective To introduce the possible effects and significances of angiogenesis and antiangiogenic in the development and treatment of hepatocellular carcinoma (HCC).

Results Angiogenesis played a significant role in the development and therapy of HCC, and the development and metastasis of HCC could be effectively suppressed by antiangiogenic therapy. This might provide a new approach for the treatment of HCC. Conclusion Comprehending the molecular mechanism of angiogenesis and applying antiangiogenic therapy will contribute a lot for the prevention and treatment of HCC.
Over the past 20 years, transcatheter mitral valve edge-to-edge repair (TEER) has become an important treatment option for patients with severe mitral regurgitation (MR) who are at high surgical risk. Initially, several landmark clinical studies established the basis of TEER for primary and secondary MR, but they only involved clinically stable patients with appropriate mitral valve anatomy. With the increasing experience of interventional therapy, the iteration of equipment and the improvement of intraoperative imaging technology, the scope of use of TEER has been continuously expanded, and its indications have been continuously expanded to more complex mitral valve lesions and clinical situations. Therefore, in clinical practice, selecting the appropriate device according to the individual anatomical characteristics of the patient can minimize MR and complications, thereby optimizing immediate and long-term prognosis. This article mainly introduces the pathogenesis and related mechanisms of MR, the main TEER devices and their clinical evidence, the limitations of TEER, and the future development direction.
Heritable aortic disease (HAD) is characterized by thoracic aortic aneurysm/dissection with strong genetic predisposition and high clinical phenotypic heterogeneity. HAD is one of the main causes of sudden death. Early diagnosis of this disease is difficult because of atypical clinical symptoms, leading to the deterioration of disease with the development of aortic aneurysm, aortic dissection or sudden death. Genetic testing plays an important role in the early diagnosis, standardized follow-up, screening of family members, genetic counseling and individualized treatment of HAD. This review focused on the application of genetic testing in the standardized diagnosis and treatment of HAD.
Objective To study the results of in situ microwave thermocoagulation therapy for liver neoplasms. Methods Thirty-one patients (male 28, female 3) with liver neoplasms underwent in situ microwave thermocoagulation therapy in recent 4 years were studied. The time of the therapy arranged from 2 to 6 minutes with the core temperature from 110℃ to 125℃. Twenty six of the thirty one (83.9%) were followed up. Results Ninty point three percent of these patients have a good result. The average survival time after the operation was 19.7 months. One-year and three-year survival rate were 77.4% and 38.7%, respectively. Conclusion The in situ microwave thermocoagulation therapy have the advantages of causing slight trauma, promoting repair, good tolerance and curative effectiveness. It’s a simple, safe and effective method with less adverse effect for treating the liver neoplasms, especially for unresectable neoplasms.
ObjectiveTo investigate the effectiveness of modified extensor indicis proprius (EIP) tendon transfer for reconstruction of spontaneously ruptured extensor pollicis longus (EPL) tendon by comparing with the traditional EIP tendon transfer. MethodsBetween January 2009 and December 2011, 11 cases of spontaneously ruptured EPL tendon were treated by modified EIP tendon transfer to reconstruct extension function (modified group). On the base of traditional procedure, the proximal end of EPL tendon was sutured with EIP tendon and the distal end of EIP tendon was crossed round extensor pollicis brevis (EPB) tendon and sutured back with EPL tendon. A specific EI-EPL evaluation method (SEEM) was used to measure the EPL tendon function after transfer. The result was compared with that of the other 18 cases undergoing traditional operation (traditional group). There was no significant difference in gender, age, disease duration, and injury causes between 2 groups (P gt; 0.05). ResultsAll incisions healed by first intention. In traditional group, 5 cases were out of follow-up, and the other 24 cases were followed up 1 year and 6 months on average (range, 8 months-2 years and 6 months). At the last follow-up, according to the evaluation of SEEM, the thumb elevation and flexion deficits of modified group were significantly less than those of traditional group (P lt; 0.05). The independent elevation deficit of the index finger of modified group was similar to that of traditional group (P gt; 0.05). The effectiveness was excellent in 9 cases and good in 2 cases with an excellent and good rate of 100% in modified group, and was excellent in 5 cases, good in 6 cases, and fair in 2 cases with an excellent and good rate of 84.6%. The effectiveness of modified group was significantly better than that of traditional group (χ2=0.03, P=0.03). ConclusionReconstruction of EPL tendon function by modified EIP tendon transfer is effective and easy. It can increase strength of the transferred tendon and obtain satisfactory results, but the long-term effectiveness needs further follow-up.
Objective To access the efficacy and safety of different doses of metoprolol for patients with chronic heart failure. Methods We searched databases such as MEDLINE, EMbase, The Cochrane Library, CBM and CMCC. The search was conducted in March 2006. Randomised controlled trials, systematic reviews, and current guidelines of chronic heart failure were reviewed. The efficacy and safety of the high-dose (≥100 mg/d) and low-dose metoprolol (lt;100 mg/d) were compared. Results Only one small-scale, short-term randomised trial met our inclusion criteria. This found that metoprolol 100 mg/d was more effective than 25 mg/d and 50 mg/d. A sub-group analysis of MERIT-HF recommended individualized titration for drug administration. Most guidelines suggested that the administration of metoprolol CR/XL for chronic left ventricular systolic dysfunction should be performed by titrating up to 200 mg/d or the maximum tolerance dose. Patients receiving 100 mg/d might have more adverse events than those receiving a lower dose than this. However, in the long-term, it’s the benefits of high-dose treatment outweighed its risks. Race-related differences in tolerance or dose-related adverse effects were not found. Conclusion We couldn’t determine an optimal dose based on the existing evidence, but a target dose of metoprolol CR/XL 200 mg/d is safe and effective. We are unable to draw any conclusions about the relationship between dose and adverse effects.
ObjectiveTo review the research progress on the establishment of prevertebral pathway in the treatment of unilateral total brachial plexus injury, cerebral palsy, stroke, and traumatic brain injury by contralateral C7 nerve root transfer.MethodsThe literature about contralateral C7 nerve root transfer via prevertebral pathway at home and abroad was extensively reviewed, and the development, changes, advantages and disadvantages of various operation methods were analyzed and summarized.ResultsAfter unilateral total brachial plexus injury, cerebral palsy, stroke, and traumatic brain injury, it can be repaired by a variety of surgical methods of the contralateral C7 nerve root transfer via prevertebral pathway, which include the anterior subcutaneous tissue tunnel of the vertebral body, the passage under the sternocleidomastoid muscle, the posterior pharyngeal space and the anterior vertebral fascia passage, the modified posterior esophageal anterior vertebral passage, the anterior vertebral passage that cuts off the bilateral anterior scalene, and Huashan anterior pathway, etc. Among them, how to establish the shortest, safe, and effective way of anterior vertebral canal has been paid more attention and discussed by peripheral nerve repair doctors.ConclusionIt is a safe and effective surgical method to repair unilateral total brachial plexus injury, cerebral palsy, stroke, and traumatic brain injury patients with contralateral C7 nerve root transfer via prevertebral pathway.
Objective To investigate and evaluate the clinical features, diagnostic methods, surgical management and postoperative adjuvant therapy of thymic carcinoma so as to improve the treatment outcome. Methods Forty-three patients of thymic carcinoma , surgically intervened and pathologically confirmed in Peking Union Medical College Hospital through June 1961 to June 2004, were retrospectively analysed. Complete resection of the tumor was performed in 15 patients, partial or incomplete expiration in 23 , exploratory thoracotomy and biopsy in 5. Results All tumors were found inencapsulated and invading the surroundings,including pericardium, superior vena cava, left or right innominate vein, rnediastinal pleura, phrenic nerve and lung. In this series there was no perioperative death. Eight patients died within the first year postoperatively, 4 died within the second year postoperatively, 2 and 1 patients died in the 5th and 8th year postoperatively respectively. Through half to 18 years follow-up, according to the life table method, the 1,3,5 and 8 year survival rate were 68.29%, 56. 67%, 41.56% and 27. 71% respectively. Conclusions Thymic carcinoma is different from malignant thymoma in clinical manifestations, radiological features, pathological characteristics and prognosis, hence it is very important for thoracic surgeons to pay more attention to those differentiation. Chest CT is an effective method for diagnosis of thymic carcinoma. It is emphasized on that aggressive radical resection of the tumor with involved tissue or organs, even removal of superior vena cava and subsequent reconstruction of vessel, will effectively extend long-term survival. Postoperative radiotherapy and combination adjuvant chemotherapy, especially based on cisplatin, play a significant role in improvement of prognosis.
