        • Clinical analysis of laparoscopic common bile duct reexploration in treatment of bile duct stones

          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.

        • Clinical analysis of reoperation for differentiated thyroid cancer

          Objective To analyze clinical features of reoperation patients with differentiated thyroid cancer, and to explore reason, surgical pattern and therapeutic effectiveness of reoperation. Method The clinical data of 80 patients with differentiated thyroid cancer underwent reoperation from January 2012 to June 2016 in Peking Union Medical College Hospital were analyzed retrospectively. Results ① Eighty (5.37%) patients with differentiated thyroid cancer underwent reoperation were identified from a total of 1 491 patients with thyroid cancer in our treatment team. Twenty-seven cases were males, 53 cases were females. The male to female ratio was 1∶1.96. The age was (44±13) years with a range from 14 to 66 years. The median time between reoperation and the first operation was 16.8 months with a range from 8 days to 17 years. ② Thirteen cases underwent reoperation because of uncertain frozen sections, and the reoperation style was residual lobectomy and selective lymph node dissection. Sixty-seven cases underwent reoperation because of local recurrence or metastasis, 15 of them accepted residual lobectomy and selective lymph node dissection while the other 52 accepted selective lymph node dissection. ③ The rate of residual in thyroid cancer confirmed by postoperative pathology was 18.8% (15/80). The rate of cervical lymph node metastasis was 63.8% (51/80). The temporary laryngeal recurrent nerve injury occured in 6 cases, the temporary hypocalcemia occured in 9 cases, and the lymphorrhagia occured in 2 cases. ④ The hospitalization time was (6.50±0.97) d with a range from 3 to10 d, the time of drainage tube remove was (2.41 ±0.95) d with a range from 2 to 7 d. Seventy-three cases were followed up from 3 to 58 months with (32±18) months, 4 of them underwent operation once again because of local recurrence, no distant metastasis or death happened. ⑤ The proportion of male patients in reoperation patients was significantly higher than that of the first operation patients (P<0.05). The proportion of patients aged <45 years, the average hospitalization time, the average time of drainage tube remove, and the postoperative complications rate had no significant differences between the patients with the first operation and the patients with reoperation (P>0.05). Conclusions For reoperation patients, proportion of male patients is higher. Reoperation is proper treatment for patients with residual lobe or local recurrence or metastasis for differentiated thyroid cancer. Serious complications could be avoided by suitable surgical pattern and careful dissection during operation. Residual lobectomy and selective lymph node dissection are suggested for reoperation.

        • Reoperation after Mechanical Valve Prosthesis Replacement: An Analysis of 105 Cases

          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 ⅠⅡ. The causes of mortality included 1 case of multiple organ failure, 1 case of low cardiac output after operation, 1 case of aortic pseudoaneurysm 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. Followup 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. 

        • Aortic-mitral annular enlargement technique in re-valve surgery: A retrospective study in a single center

          Objective To investigate and evaluate the safety and efficacy of the aortic-mitral annular enlargement technique (double annular enlargement) in patients with small-size valve prostheses after prior valve surgery. MethodsThe clinical data of patients who underwent double valve annular enlargement in Wuhan Asia Heart Hospital from April 2020 to April 2022 were retrospectively analyzed. Results A total of 30 patients were collected, including 2 males and 28 females aged 9-78 (52.71±3.53) years. All patients had previous heart valve surgery, including 1 patient receiving the third heart surgery. All patients were operated on successfully and there were no postoperative in-hospital deaths. There was no postoperative bleeding which needed a secondary open-chest hemostasis, and one patient underwent permanent pacemaker implantation due to postoperative sick sinus syndrome. The mean diameter of the implanted prosthetic aortic valve was 24.23±1.60 mm, which was significantly larger than that of the preoperative aortic valve (21.03±1.90 mm, P<0.001). The mean diameter of the implanted prosthetic mitral valve was 28.33±1.21 mm, which was significantly larger than that of the preoperative mitral valve (25.43±0.84 mm, P<0.001). The mean peak gradient difference across the prosthetic aortic valve on postoperative echocardiography was 18.17±6.44 mm Hg, which was significantly lower than that of the preoperative aortic valve (82.57±24.48 mm Hg, P<0.001). The mean peak gradient difference of the postoperative prosthetic mitral valve was 12.73±5.45 mm Hg, which was significantly lower than that of the preoperative mitral valve (19.43±8.97 mm Hg, P=0.003). Conclusion The double annular enlargement technique is safe and effective for reoperation in patients with a history of valve surgery with a small aortic root to obtain both a larger size prosthetic valve for a larger orifice area and stability of the mitral-aortic valve union, resulting in good postoperative hemodynamic characteristics and clinical outcomes.

        • Application of Chimney technique in mitral valve reoperation: A retrospective study in a single center

          Objective To investigate and evaluate the safety and effectiveness of the Chimney technique in mitral valve reoperation. Methods The clinical data of mitral valve reoperation patients who underwent Chimney surgery in Wuhan Asia Heart Hospital from 2019 to 2021 were retrospectively analyzed. Results A total of 26 patients were collected, including 7 males and 19 females, aged 27-67 (53.46±11.18) years. All patients had previous mitral valve surgery, including 23 mitral valve replacements and 3 mitral valve repairs. All patients received Chimney technique using the ideal artificial sized mitral valve, and 1 patient died of neurological complications in hospital. The cardiopulmonary bypass time and the aortic cross-clamping time were 231.11±77.05 min and 148.50±52.70 min, respectively. The mean diameter of the implanted mitral valve prosthesis was 29.08±0.68 mm, which was statistically different from pre-replacement valve prosthesis size of 26.69±0.77 mm (P<0.001). The mean transvalvular pressure gradient of the prosthetic mitral valve measured on postoperative echocardiography was 14.77±5.34 mm Hg, which was statistically different from preoperative value of 20.92±9.83 mm Hg (P=0.005). Conclusion The Chimney technique is safe and effective for reoperation in patients with small mitral annuli, which can not only reduce the risk of reoperation, but also obtain larger prosthetic valve implants with good hemodynamic characteristics and clinical outcomes.

          Objective To explore the factors associated with the occurrence of unplanned reoperations. Methods Surgical cases at Peking University Shenzhen Hospital from 2015 to 2023 were collected. After excluding unplanned reoperations, according to whether unplanned reoperation occurs, the included surgeries would be divided into the generate unplanned reoperation group and the non-generate unplanned reoperation group. Based on gender and age, the included surgery was matched with a propensity score of 1∶4 ratio. A logistic multiple regression model was established to investigate the influencing factors of unplanned reoperations. Results A total of 4 485 surgeries were included. Among them, there were 891 cases in the generate unplanned reoperation group and 3 594 cases in the non-generate unplanned reoperation group. The logistic regression analysis of the influencing factors of unplanned reoperation showed that different surgical levels, American Society of Anesthesiologists grades, surgical types, anesthesia methods, surgical time, and whether the unplanned reoperation discussion system can all affect unplanned reoperation (P<0.05). Conclusions The surgical level, American Society of Anesthesiologists grades, surgical types, anesthesia methods, surgical time, and whether the unplanned reoperation discussion system are influencing factors for the occurrence of unplanned reoperation. The occurrence of unplanned reoperation involves multiple levels of both the medical side and the patient side. It is necessary to formulate patient classification and early warning management and procedural prevention of unplanned reoperation based on each factor to ensure patient safety.

          ObjectiveTo evaluate the safety and efficacy of peripheral cannulation for cardiopulmonary bypass (CPB) in patients with reoperation of congenital heart disease. MethodsThe perioperative data of patients with congenital heart disease who underwent reoperation in Fuwai Hospital from 2019 to 2020 were retrospectively collected. They were divided into two groups according to the cannulation methods: a central group and a peripheral group. The prognosis of the patients was analyzed. Results A total of 80 patients were collected, including 43 patients in the central group, and 37 pateints in the peripheral group. In the central group, the median age was 18 (14, 32) years, and 21 patients were male. The median age of the peripheral group was 16 (10, 27 ) years, and 18 patients were male. The CPB time in the peripheral group was 201 (164, 230) min, which was longer than that in the central group [143 (97, 188 ) min, P<0.001]. The lactate after CPB in the peripheral group was statistically higher than that in the central group [2 (1, 2 ) mmol/L vs. 1 (1, 1) mmol/L, P=0.002]. The dosage of albumin use during CPB in the peripheral group was statistically higher than that in the central group [10 (0, 20) g vs. 0 (0, 0) g, P=0.004]. There was no statistical difference in the postoperative dosage of red blood cells use [0 (0, 2) U vs. 0 (0, 0) U, P=0.117], mechanical ventilation time [14 (11, 19) h vs. 13 (10, 15) h, P=0.296], ICU stay time [43 (23, 80) h vs. 40 (20, 67) h, P=0.237] or postoperative hospital stay time [10 (7, 12) d vs. 8 (7, 10) d, P=778] between the two groups. ConclusionIt’s safe and efficient to establish CPB through peripheral cannulation in patients with complex congenital heart disease undergoing reoperation.

          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.
