ObjectiveTo evaluate the effectiveness of mitral valve repair for mitral regurgitation. MethodsWe retrospectively analyzed the clinical data of 47 patients underwent mitral repair in General Hospital of Ningxia Medical University between January 2010 and June 2014 year. There were 36 males and 11 females with age of 10 months to 65 years, mean age of 42.38±15.27 years. ResultsThere was no operative death within follow-up time of 18±7 months (ranged 14 to 1 586 days). Mitral valve function was normal or traces regurgitation in 33 patients (70.21%). Mild mitral regurgitation occurred in 11 patients (23.40%). Postoperative transesophageal echocardiography showed that 2 patients (4.26%) had moderate regurgitation. They underwent mitral valve repair again and cured. One patient (2.13%) underwent mitral valve replacement because of moderate to severe regurgitation. The dimensions of left atrium and left ventricle obviously decreased and heart function improved significantly compared with preoperative ones. ConclusionStrict control of surgical indications for different valve disease, the use of mitral valve repair technique, mitral surgery can get a good clinical efficacy. Preoperative diagnosis by transesophageal echocardiography, intraoperative monitoring, and immediate postoperative assessment for mitral valve repair results provide good technical support.
Objective To review the complex situation，surgical experience，and surgical technique of laparoscopic cholecystectomy （LC）．Methods The clinical data of 86 patients who underwent LC in our hospital and the consulting hospitals from February 2005 to April 2011 were retrospectively analyzed．According to the complicated conditions，the different surgical techniques were applied during LC such as lamellar dissection，aspirater stripping method，laparoscopic suture，and intraoperative cholangiography．Results The operation time was （68±23）min （25－210 min），blood loss was （55±13）ml （15－200 ml）．LC was successfully performed in 84 of 86 cases．Only two patients received transferring laparotomy because of scar tissue in Calot triangle that was hard to dissect．No severe complications occurred，such as biliary leakage，bleeding after operation，stricture of bile duct，retained calculus，and so on．All the patients were cured before discharge．Conclusion Lamellar dissection，aspirater stripping method，and laparoscopic suture combined with the view of laparotomy can be used to deal with complicated LC successfully．
Doubly committed sub-arterial ventricular septal defect (VSD) is a unique type of VSD which is located beneath both the aortic and pulmonary valve. Open-heart repair is traumatic especially for pediatric patient while trans-catheter device closure is also not suitable for this type of VSD. Minimally invasive per-ventricular device closure has been introduced as an alternative method in the treatment of doubly committed VSD with encouraging results. In the review, we will illustrate the surgical technique as well as perioperative management strategy as for this technique in treating doubly committed VSD.
Objective To discuss the operative technique and curative effect of minor-incision cholecystectomy. Methods The clinical data of 672 patients with application of mini-cholecystectomy from June 2001 to June 2009 were analyzed. Perioperative management and operative technique were emphasized. Results Six hundred and fifty-two cases (97.0%) were cured with mini-cholecystectomy and 20 cases (3.0%) with incision lengthened. Operation time was （40.0±10.0） min. One case with hemorrhoea during operation was cured by interventional embolotherapy. Bile duct injury was found in 1 case during operation， and adopted suture with T tube. There were no infection of incisional wound or death in this study. Conclusion On the basis of skillful conventional cholecystectomy, by controlling indication and improving operative technique, it is an economical and safe way to perform minor-incision cholecystectomy.
