Objective To evaluate safety, efficacy, and indications of laparoscopic bile duct reexploration in treatment of bile duct stones. Methods Fifty-seven patients with bile duct stones who underwent laparoscopic common bile duct reexploration (laparoscope group) and 62 patients with bile duct stones who underwent open common bile duct reexploration (laparotomy group) were included into this study from February 2013 to February 2017 in the Renmin Hospital of Wuhan University. The intraoperative and postoperative data of the patients were documented and analyzed. Results All the operations were performed successfully and all the patients had no extra-damage during the operation. One case was converted to the laparotomy due to the intraabdominal serious adhesion in the laparoscope group. Compared with the laparotomy group, the amount of intraoperative blood loss was less, the first time of anal exhaust was earlier, the rates of postoperative analgesia and incision infection were lower, and the length of hospital stay was shorter in the laparoscope group, there were significant differences (P<0.05). There were no significant differences in the operative time, the hospitalization expense, primary suture rate of common bile duct, and the rates of postoperative complications such as the bile leakage, bile duct stricture, and residual stone between the laparoscope group and the laparotomy group (P>0.05). Conclusion With experienced skills and strict surgical indications, laparoscopic common bile duct reexploration is safe and effective in treatment of bile duct stones, and it has some advantages including less bleeding, rapid recovery, and shorter hospitalization time.
Objective To evaluate the efficacy of a combination of beating-heart minimally invasive approach and leaflets augmentation technique treating severe tricuspid regurgitation (TR) after cardiac surgery. Methods From January 2015 to August 2017, patients undergoing reoperative tricuspid valve repair (TVP) with minimally invasive approach and leaflets augmentation were enrolled. Cardiopulmonary bypass (CPB) was established via femoral vessels and the procedures were performed on beating heart with normothermic CPB. A bovine pericardial patch was sutured to leaflets to augment the native anterior and posterior leaflets. Other repair techniques, such as ring implantation and leaflet mobilization, were also applied as needed. Results A total of 28 patients (mean age 55.6±10.1 years, 5 males, 23 females) were enrolled. One patient was converted to median sternotomy due to pleural cavity adhesion. Twenty-seven patients underwent totally endoscopic TVP with leaflets augmentation. No patients was transferred to tricuspid valve replacement. Two patients died in hospital. All patients were followed up for 7.4±5.0 months and there was no late death and reoperation. Regurgitation area was converted from 20.7±10.1 cm2 to 3.3±3.3 cm2 after TVP according to the latest echocardiography (P<0.001). Conclusion Minimally TVP with leaflets augmentation is effective in treating severe isolated TR after primary cardiac surgery. It can significantly increase success rate of tricuspid valvuloplasty and decrease the surgical trauma.
Objective To investigate the value of indocyanine green fluorescence imaging in common bile duct reexploration. Methods The clinical data of 32 patients who underwent open common bile duct reexploration in the Affiliated Hospital of Southwest Medical University from January 2018 to December 2020 were collected retrospectively. All patients divided into the control group (conventional exploration group, 20 patients) and the fluorescence imaging group (using indocyanine green fluorescence imaging, 12 patients) according to the operational manner. The intraoperative and postoperative results of two groups were analyzed. Results The operative time [(165.2±6.9) min vs. (130.8±5.5) min], the time to find extrahepatic bile duct [(43.9±3.8) min vs. (23.1±4.1) min] and the amount of bleeding [(207.7±7.7) mL vs. (127.5±15.3) mL] in the control group were longer or more than those in the fluorescence imaging group (P<0.05). The incidence of postoperative infection in the control group [7 cases (35.0%) vs. 0 cases (0.0%)] and the length of hospital stay [(10.8±2.8) d vs. (7.1±1.3) d] were higher or longer than those in the fluorescence imaging group (P<0.05). There were no significant difference between the two groups in the incidence of postoperative bile fistula [6 cases (30.0%) vs. 2 cases (16.7%)] and the incidence of residual stones [3 cases (15.0%) vs. 3 cases (25.0%), P＞0.05]. Conclusion Indocyanine green fluorescence imaging appears to be a feasible, expeditious, useful, and effective imaging method while performing reexploration.
Abstract： Objective To summarize our operative experiences of cardiac reoperation after mechanical valve prosthesis replacement and investigate the causes of reoperation and the perioperative techniques and operation methods. Methods From January 2001 to December 2008, we performed reoperation on 105 patients (59 males and 46 females, aged 50.2±10.6 years old) who had undergone mechanical valve prosthesis replacement. Among the patients, there were 31 cases of mitral valvular replacement (+ tricuspid valvular plasticity), 38 cases of aortic valvular replacement (+ tricuspid valvular plasticity), 11 cases of Bentall procedure, 7 cases of mitral and aortic bivalvular replacement (+tricuspid valvular plasticity), 8 cases of tricuspid valvular replacement, 6 cases of repairing of prosthetic leakage, and 4 others cases. The time interval between two operations was 3 months to 18 years (46.3 ±31.9 months). Before reoperation, the cardiac function (NYHA) of the patients was class Ⅱ in 27 patients, class Ⅲ in 53 patients, and class Ⅳ in 25 patients. Results There were 6 hospital deaths with a mortality of 5.71%(6/105). All others recovered to NYHA class ⅠⅡ. The causes of mortality included 1 case of multiple organ failure, 1 case of low cardiac output after operation, 1 case of aortic pseudoaneurysm rupture, 1 case of severe infection due to brain complication and 2 cases of prosthetic valve endocarditis (PVE). The causes for cardiac reoperation after mechanical valve prosthesis replacement were 67 cases of prosthetic leakage (63.80%), 16 cases of PVE (15.23%), 14 cases of prosthetic thrombosis (13.33%) and 8 cases of other valvular anomalies. Followup was done for 11 to 107 months, which showed two cases late deaths of cardiac arrest and cerebral hemorrhage. Conclusion Patients who have received mechanical valve prosthesis replacement may undergo cardiac reoperation due to paravalvular prosthetic leakage, paravalvular endocarditis, and prosthetic thrombosis. The keys to a successful cardiac reoperation include appropriate preoperative preparations, operational timing, and suitable choosing of cardiopulmonary bypass and operational skills.
Objective To summary the clinical experience of liver retransplantation （RLT）， and to improve the effect. Methods The clinical data of 62 cases who had received RLT in our institute from Jan. 2003 to Jun. 2012 were analyzed retrospectively. The survival rates of patients with different interval between two liver transplantation （LT） were calculated， and the data of patients who died and survived during perioperative period after operation were compared and analyzed. Results The 1-， 2-， and 5-year cumulative survival rates of 62 patients were 67.7%， 59.7%， and 56.4%， of early stage RLT patients were 38.5%， 38.5%， and 30.8%， of later stage RLT patients were 75.5%， 65.3%， and 63.3%， respectively. There were 28 patients died after operation， and 20 patients （71.4%） died during perioperative period， whose major cause of death were infection （65.0%， 13/20）， in addition， 4 cases （20.0%） died of multiple organ failure， 2 cased （10.0%） died of hepatic artery complication， 1 case （5.0%） died of portal vein complication. Eight cases （28.6%） died after perioperative period in reason of tumor recurrence. The model for end-stage liver disease （MELD） score 〔（26.95±9.28） score vs. （14.23±9.06） score〕， creatinine （Cr） level 〔（157.3±88.0） μmol/L vs.（69.8±35.9） μmol/L〕， international normalized ratio （INR） value 〔（1.676±0.744） vs.（1.124±0.286）〕， and total bilirubin （TBiL） value 〔431.8 μmol/L vs. 248.2 μmol/L〕 of patients died during perioperative period were higher than that of patients survived after perioperative period （P＜0.05）. The ratio of abnormal Cr of patients died during perioperativeperiod and survived after perioperative period were 60.0% （12/20） and 7.1% （3/42）， respectively. The 34 patients who had survived after perioperative period were all got followed-up for 3-104 months （average 49 months）. There were no tumor recurrence during the followed-up， and liver function of them were normal. Conclusions RLT is an effective method for irreversible graft failure after LT. Optimum operative time and reasonable individual immunosuppressive regimen to decrease the infection rate are all contribute to the increase of the survival rate.
