ObjectiveTo explore the effect of the reimplantation procedure with the De Paulis Valsalva graft in patients with aneurysms. MethodsWe retrospectively analyzed the clinical data of 38 patients underwent valve-sparing aortic root replacement using De Paulis graft in our hospital between September 2005 and July 2013.There were 32 male and 6 female patients at age of 45.5±12.4 years. We compared the parameters of pre-operation and post-operation and followed up the patients for 5 years. ResultsThere were 2(5.3%) deaths in hospital. The follow-up time was 2-95 months with following-up rate of 92.1%(35/38). A total of 2 patients(5.3%) had grade 3 to grade 4 aortic insufficiency. And one of these patients received aortic valve replacement after 1 year. At 5 years of following-up, one patient died of septic shock due to pacemaker infection. One patient died of kidney failure due to renal artery dissection aneurysm affected with impaired renal function and long-term hemodialysis. ConclusionThe reimplantation type of valve-sparing procedure can be facilitated by the use of the De Paulis valsalva graft and can be performed with satisfactory perioperative and mid-term results.
ObjectiveTo compare clinical efficacy of 4 kinds of surgical treatment for high transsphincter fistula. MethodsThe clinical data of 116 patients with high transsphincter fistula in Jiangsu Province Hospital of TCM from January 2012 to December 2014 were analyzed retrospectively.These patients were divided into 4 groups according to surgical treatments,including cut seton group (n=30),loose seton group (n=34),ligation of intersphincteric fistula tract group (LIFT,n=41),mucosa advancement flap group (MAF,n=11).The length of stay,incision healing time,postoperative pain score on the second day,Wexner score when healed,postoperative complications,curative status,and recurrence were observed. Results① The length of stay in the loose seton group was significantly longer than that in the LIFT group (P<0.01),cut seton group (P<0.05) or MAF group (P<0.05),but which had no differences among the other groups (P>0.05).② The incision healing time in the loose seton group was significantly longer than that in the LIFT group (P<0.01) or the MAF group (P<0.05),but which had no differences among the other groups (P>0.05).③ The postoperative pain score on the second day in the cut seton group was significantly higher than that in the other three groups (P<0.01),which in the MAF group was lower than that in the LIFT group (P<0.05),but which had no difference between the other groups (P>0.05).④The Wexner score when healed in the cut seton group was significantly higher than that in the other three groups (P<0.01),bwt which had no differences among the other groups (P>0.05).⑤ The rate of postoperative complica-tion in the LIFT group was significantly higher than that in the loose seton group (P<0.05),but which had no differences among the other groups (P>0.05).⑥ The curative rate and recurrence rate had no statistically differences among the 4 groups (P>0.05). ConclusionsCurative rate and recurrence rate in loose seton,LIFT,and MAF group are similar with cut seton group,meanwhile they could protect anal function better and relieve pain.The length of stay and the incision healing time are longer in the loose seton group.The postoperative complications in LIFT group is increased as compared with loose seton group.The postoperative pain of MAF group is slighter than that in LIFT group.Comprehensive evaluation,MAF has more advantages,but the technique is more complex.The decision should be made individually according to patients and surgeons.

Abstract： Objective To summarize our experience and clinical outcomes of preservation of posterior leaflet and subvalvular structures in mitral valve replacement（MVR）. Methods We retrospectively analyzed the clinical data of 1 035 patients who underwent MVR in Beijing An Zhen Hospital from January 2006 to March 2011. There were 562 male patients and 473 female patients with their age of 37-78（53.84±13.13）years old. There were 712 patients with rheumatic valvular heart disease and 323 patients with degenerative valve disease, 389 patients with mitral stenosis and 646 patients with mitral regurgitation. No patient had coronary artery disease in this group. For 457 patients in non-preservation group, bothleaflets and corresponding chordal excision was performed, while for 578 patients in preservation group, posterior leafletand subvalvular structures were preserved. There was no statistical difference in demographic and preoperative clinical characteristics between the two groups. Postoperative mortality and morbidity, and left ventricular size and function were compared between the two groups. Results There was no statistical difference in postoperative mortality（2.63% vs. 1.21%, P =0.091）and morbidity （8.53% vs. 7.44%, P=0.519）between the non-preservation group and preservation group, except that the rate of left ventricular rupture of non-preservation group was significantly higher than that of preservation group（1.09% vs. 0.00%, P=0.012）. The average left ventricular end-diastolic dimension （LVEDD）measured by echocardiography 6 months after surgery decreased in both groups, but there was no statistical difference between the two groups. The average left ventricular ejection fraction (LVEF) 6 months after surgery was significantly improved compared with preoperative average LVEF in both groups. The average LVEF 6 months after surgery in patients with mitral regurgitation in the preservation group was significantly higher than that in non-preservation group （56.00%±3.47% vs. 53.00%±3.13%，P =0.000）, and there was no statistical difference in the average LVEF 6 months after surgery in patients with mitral stenosis between the two groups（57.00%±5.58% vs. 56.00%±4.79%，P =0.066）. Conclusion Preservation of posterior leaflet and subvalvular structures in MVR is a safe and effective surgical technique to reduce the risk of left ventricle rupture and improve postoperative left ventricular function．
ObjectiveTo study the gastric function of vagus-preserved patients after esophagectomy, and to evaluate the significance of keeping vagus and the value of gastric tube with vagal-sparing esophagectomy. MethodsWe retrospectively analyzed clinical data of 15 patients in West China Hospital between June 2012 and January 2014. They were divided into two groups. There were 8 patients with 6 males and 2 females with average age of 57 years ranging from 44 to 77 years, in a gastric pull-up group with vagal-sparing esophagectomy. There were 7 patients with 6 males and 1 female at average age of 60 years ranging from 50 to 70 years in a gastric tube group with vagal-sparing esophagectomy. We chose 8 patients with 7 males and 1 female at average age of 62 years ranging from 47 to 69 years as a control group with a classical esophagectomy and a gastric pull-up. Then we evaluated the function of the vagal nerves and gastric reservoir after vagal-sparing esophagectomy. ResultsAll 23 surgeries were successfully performed. In subjective symptom, diarrhea was rare in the vagal-sparing esophagectomy patients and statistically more common in patients with a standard esophagectomy. Dumping and early satisfaction situation were similar among 3 groups. The 60 minutes gastric emptying rate was much better in the vagal-sparing group than that in the control group. And the esophageal manometry of the vagal-sparing group was statistically hihger than that in the control group. The gastroscope showed that the incidence of reflux esophagitis in the vagal-sparing group was statistically lower than that of the control group. There was no statistic difference in weight in the vagus-preserved group before and after the surgery while the weight decreased statistically in the control group. ConclusionsFor both esophageal replacement and gastric tube, preserving the vagus can reduce the functional dyspepsia after esophagectomy.
Objective To evaluate the effectivenss of Chinese herbal retention enema in viral hepatitis patients. Methods Such databases as The Cochrane library, PubMed, EMbase, VIP, CNKI, CBM and WanFang Data were searched from the inception to December, 2011 to collect the randomized controlled trials (RCTs) about Chinese herbal retention enema in treating viral hepatitis, and the references of the included literature were also retrieved. Two reviewers independently screened the literature according to the inclusion and exclusion criteria, extracted the data, and evaluated and cross-checked the methodological quality. Then meta-analysis was conducted using RevMan 5.0 software. Results A total of 20 RCTs involving 1 735 patients were included. The subgroup analyses based on the length of intervention time showed that: a) after 2-week intervention: the overall effective rate of the Chinese herbal retention enema group was higher than that of the control group, with a significant difference (OR=3.19, 95%CI 1.87 to 5.44, Plt;0.000 1). Compared with the control group, the Chinese herbal retention enema group better promoted the recovery of liver function by more reduction of AST (MD= ?82.50, 95%CI ?145.66 to ?19.34, P=0.01), ALT (MD= ?44.78, 95%CI 65.90 to ?23.66, Plt;0.000 1) and TBIL (MD= ?37.51, 95%CI ?74.07 to ?0.95, Plt;0.0001). b) After 1-month intervention: The overall effective rate of the Chinese herbal retention enema group was higher than that of the control group, with a significant difference (OR=4.17, 95%CI 2.37 to 7.32, Plt;0.000 01). Compared with the control group, the Chinese herbal retention enema group better promoted the recovery of liver function by more reduction of AST (MD= ?17.86, 95%CI ?29.97 to ?5.76, P=0.004), ALT (MD= ?27.84, 95%CI ?42.45 to ?13.24, P=0.000 2), and TBIL (MD= ?54.15, 95%CI ?116.52 to ?8.23, P=0.09). Conclusion Chinese herbal retention enema can improve the overall effective rate for viral hepatitis patients, alleviate virus damage to liver cell and promote liver function recovery. The commonly used Chinese medicinals for enema are Radix et Rhizoma Rhei, Herba Artemisiae Capillaris, Salvia miltiorrhiza, and Radix Paeoniae Rubra.

【Abstract】 Objective To investigate the survival rate, voiding, sexual function after nerve-sparing surgery with extended systematic extraperitoneal lateral lymphadenectomy in lower rectal cancer. Methods Three hundreds and ninety-two cases with advanced lower rectal cancer who underwent nerve-sparing surgery with radical dissection from 1996 to 2000 were reviewed. Among them,173 cases only cleared in abdominal cavity,219 cases coupled with extraperitoneal lateral lymphadenectomy. Results The metastatic rate of lateral lymph node was 17.8%(39/219),the rate of non-modal foci of metastatic disease in lateral out of the abdominal cavity was 5.9%(13/219).Local recurrence rate, the abdominal cavity group was 16.2%（28/173）; the coupled group was 9.6%（21/219）， P＜0.05. Conclusion By contrast,abdominal cavity coupled with extraperitoneal lympadenectomy acted to cut down local recurrence and to elevate 5-year survival rate,the postoperative quality of life with voiding, sexual function appeared to be seriously affected, although the radical dissection are nerve-sparing surgery.
Since the concept of total mesorectal excision (TME) was proposed and carried out in 1982, the postoperative local recurrence rate of rectal cancer has decreased significantly and the long-term survival rate has increased, thus TME has become the gold standard for middle and low rectal cancer surgery. However, the incidence of postoperative urination and sexual dysfunctions caused by pelvic autonomic nerve injury during TME operation remains high, which needs to be investigated and solved. Over the years, through systematic studies of anatomy, histology and physiology, we have confirmed that dissection anterior to Denonvilliers’ fascia for the anterior wall of rectum, and thus partial resection of Denonvilliers’ fascia, were the leading cause of nerve injury during TME operation. On the contrary, dissection posterior to Denonvilliers’ fascia and entire preservation of Denonvilliers’ fascia are feasible and necessary. Moreover, through anatomical study, Wei’s Line, the surgical marker line of Denonvilliers’ fascia is discovered for the first time, and thus innovative TME (iTME) navigated with Wei’s Line is proposed. The multi-center clinical study has confirmed that compared with traditional TME surgery, the incidences of postoperative urination and sexual dysfunctions in iTME group decrease significantly, with comparable oncologic outcomes, suggesting that iTME surgery could be a better choice for male patients with middle and low rectal cancer at specific stages. This study systematically reviews the research process and operation standard of iTME, and summarizes the application status and future prospects of iTME.
