Types of reconstruction of the extrahepatic biliary duct included: excision of cystic dilatation and Rorx-en-Y hepatoductojejunostomy in 25 cases, and interposition of jejunum and hepatoductoduodenostomy in 9 eases. for those cases having fusiform dilatation, interposition of jejunum and hepatoductoduodenostomy，cases and Rorx-en-Y-hepatoductojejunostmy 5 cases.The follow-up period averajed 6.5 years. Forty nine patients were recoverwd from the teatment and 1 patient died.
【Abstract】ObjectiveTo explore risk factors of bile leakage after primary ductal closure following choledochotomy. MethodsA retrospective clinical analysis was made in 148 cases of Ttube drainage and 154 cases of primary common bile duct suture following choledochotomy admitted to our hospital from January 1999 to June 2003. Results Postoperative bile leakage was seen in 11 patients of the group with Ttube drainage and in 16 patients of the group with primary suture respectively, there was no significant difference(Pgt;0.05).In the group with primary common bile duct suture,the occurrence of bile leakage was relative with hyperglycemia(Plt;0.05)，hypoproteinemia (Plt;0.01)，bile duct repeated sutures(Plt;0.01)and positive bacterial culture in bile(Plt;0.05). Bile leakage was not relative with elder age (Pgt;0.05).Conclusion It is the key factors,including chosing appropriate patients, intraoperative special examination, careful manipulation and effective medical treatment that can reduce the morbidity of bile leakage.
In order to protect the integrity and function of the digestive system, duodenum-preserving total pancreatic head resection is becoming the surgical method which was chosen by more and more doctors for benign lesions or low-grade malignant tumors of the pancreatic head. With the development of minimally invasive concepts and techniques, laparoscopic technology has brought unique advantages to this surgery. In this paper, a series of problems such as the development process and indications of laparoscopic duodenum-preserving total pancreatic head resection were discussed, and the core techniques of surgery and how to reduce the occurrence of complications were emphasized. The aim is to improve the therapeutic effect and quality of life of patients through reasonable surgical methods and treatment strategies.
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.
Objective To evaluate the clinical effectiveness of ERCP/S+LC and LC+LCBDE in cholecystolithiasis and choledocholithiasis. Methods A fully recursive literature search was conducted in MEDLINE, EMbase, Cochrane Central Register of Controlled Trials in any language. By using a defined search strategy, both the randomized controlled trials (RCTs) and controlled clinical trials on comparing ERCP/ S+LC with LC+LCBDE in cholecystolithiasis and choledocholithiasis were identified. Data were extracted and evaluated by two reviewers independently. The quality of the included trials was evaluated. Meta-analyses were conducted using the Cochrane Collaboration’s RevMan 5.0.2 software. Results Fourteen controlled clinical trials (1 544 patients) were included. The results of meta-analyses showed that: a) There were no significant difference in the stone clearance rate between the two groups (RR=0.96, 95%CI 0.92 to 1.01, P=0.14); b) There were no significant difference in the residual stone rate between the two groups (OR=1.05, 95%CI 0.65 to 1.72, P=0.83); c) There were no significant difference in the complications morbidity between the two groups (OR=1.12, 95%CI 0.85 to 1.55, P=0.48); d) There were no significant difference in the mortality during follow-up visit between the two groups (RD= 0.00, 95%CI –0.03 to 0.03, P=0.84); e) The length of hospital stay in the LC+LCBDE group was shorter than that of the ERCP/S+LC group with significant difference (WMD= 1.78, 95%CI 0.94 to 2.62, Plt;0.000 1); and f) The LC+LCBDE group was superior to the ERCP/S+LC group in the aspects of procedure time and total hospital charges. Conclusion Although there aren’t differences in the effectiveness and safety between the ERCP/S+LC group and the LC+LCBDE group, the latter is superior to the former in procedure time, length of hospital stay and total hospital charges. For the influencing factors of lower quality and astable statistical outcomes of the included studies, this conclusion has to be verified with more strictly designed large scale RCTs.
ObjectiveTo evaluate the early and mid-term outcomes of GK bileaflet mechanical valve applied in mitral valve replacement. MethodsTwenty patients with rheumatic mitral stenosis underwent mitral valve replacement in our hospital from March 2008 to June 2011. Ten patients of them chose GK bileaflet mechanical valve for surgery (a GK group, 5 males and 5 females, aged 56.4±8.9 years), while the other 10 patients chose Medtronic Open Pivot mechanical valve (a Medtronic group, 4 males and 6 females, aged 50.2±8.0 years). The preoperative, perioperative and postoperative data were analyzed and compared between the two groups. Cardiac CT angiography (CTA) and transesophageal echocardiography (TEE) were performed to evaluate leaflets opening angle, the morphological features of the mechanical valve and the hemodynamic features in the third year after surgery during the follow-up. ResultsNo mortality, defect, low cardiac output syndrome or bleeding after surgery occurred in either group. The result of 3-year follow-up showed that the function of the mechanical valve showed no difference between the two groups. Cardiac CTA and TEE showed good morphological features in all patients. ConclusionThe GK bileaflet mechanical valve has equivalent effect as Medtronic Open Pivot mechanical valve for mitral valve replacement during the 3-year follow-up.
ObjectiveTo evaluate the effectiveness of Oxford mobile-bearing bipolar prosthesis unicompartmental knee arthroplasty (UKA) in the treatment of single compartmental knee osteoarthritis. MethodsBetween June 2011 and July 2013, 22 cases of single compartmental knee osteoarthritis were treated by Oxford mobile-bearing bipolar prosthesis UKA. Of 22 cases, 8 were male and 14 were female with an average age of 65 years (range, 45-80 years); the left knee was involved in 12 cases, and the right knee in 10 cases, with a mean disease duration of 32.5 months (range, 8-90 months). The mean weight was 55.2 kg (range, 50-65 kg), and the mean body mass index was 20.8 kg/m2(range, 17-25 kg/m2). Osteoarthritis involved in the single knee medial compartment in all patients. Knee society score (KSS) and range of motion (ROM) were measured to evaluate the knee joint function. ResultsPrimary healing of incision was obtained in all patients, and there was no complication of infection, bedsore, or deep venous thrombosis. Postoperative follow-up was 2-4 years (mean, 3.2 years). The X-ray films showed good position of prosthesis, no prosthesis dislocation, or periprosthetic infection during follow-up. Knee ROM, KSS function score, and KSS clinical score were significantly improved at 1 week after operation and at last follow-up when compared with preoperative ones (P＜0.05), but no significant difference was shown between at 1 week and at last follow-up (P>0.05). ConclusionOxford mobile-bearing bipolar prosthesis UKA is an effective method to treat single compartmental knee osteoarthritis, with the advantages of less trauma, earlier rehabilitation exercise, near physiological state in joint function, and less risk of complications.
Objective To investigate the method of the treatment on cholecystolithiasis combined with calculus of common bile duct (CBD) by laparoscopy with combination of choledochoscope and duodenoscope and its significances. Methods Forty-two patients with cholecystolithiasis combined with calculus of CBD were treated by laparoscopy with combination of choledochoscope and duodenoscope from Jan. 2007 to Dec. 2008 in this hospital. Under general anesthesia, laparoscopic cholecystectomy was performed first, then the anterior wall of CBD was opened, calculus of CBD was treated by choledochoscope and duodenoscope intraoperatively. Then primary suture of the CBD was performed under laparoscope and nasobiliary drainage duct was placed. Results One case was converted to laparotomy, 41 cases succeeded and left hospital after being taken off the nasobiliary drainage duct in 5-7 d. No case died, no bile leakage, no bleeding or perforation of upper digestive tract, and no acute pancreatitis happened after operation. Conclusion Laparoscopy with combination of choledochoscope and duodenoscope treating cholecystolithiasis combined with calculus of CBD is a safe, effective and quickly recovering method with less sufferings and trauma.
Objective To investigate the effect of laparoscopy combined with choledochoscopy on common bile duct (CBD) stones with primary suture of the CBD. Methods Totally 523 patients of gallbladder stone companied with CBD stones or choledochectasia (diameter ≥0.8 cm) from September 1998 to December 2008 were retrospectively analyzed. Results The primary suture of the CBD incision was successfully performed in 487 patients. The CBD stones were completely removed during the operation in 400 patients. Nothing was found in 87 cases. In 10 cases conversion to open surgery were performed and in 26 cases the T tube drainage was put into the CBD in choledocholithotomy. Average operative time was 90 min and average bleeding volume was 50 ml. All patients took food at 24 h, returned general activity on 2-3 d and discharged on 5 d after operation. Postoperative biliary leakage occurred in 29 cases with drainage average volume of 35 ml/d and continued 1-6 d, which were cured by non-operation therapy. Conclusions The primary suture of the CBD during the laparosocopy combined with choledochosopy in choledocholithotomy is a safe and effective operation with less invasion, less pain and quicker recovery. CBD incision suture without T tube drainage can be done when CBD stones are cleared completely and no stenosis is found in extrahepatic bile duct.
