ObjectiveTo review the research on the reasons of unplanned reoperation (URP) for degenerative lumbar spine diseases, and to provide new ideas for improving the quality of surgery for degenerative lumbar spine diseases. Methods The literature about the URP of degenerative lumbar spine diseases at home and abroad in recent years was reviewed and analyzed. Results At present, the reasons for URP include surgical site infection (SSI), hematoma formation, cerebrospinal fluid leakage (CSFL), poor results of surgery, and implant complications. SSI and hematoma formation are the most common causes of URP, which happen in a short time after surgery; CSFL also occurs shortly after surgery but is relatively rare. Poor surgical results and implant complications occurred for a long time after surgery. Factors such as primary disease and surgical procedures have an important impact on the incidence of URP. ConclusionThe main reasons for URP are different in various periods after lumbar spine surgery. Interventions should be given to patients with high-risk URP, which thus can reduce the incidence of URP and improve the surgery quality and patients’ satisfaction.
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 analysis causes of reoperation for primary hyperparathyroidism and its clinical characteristics. Method The clinical data of the patients with primary hyperparathyroidism who had undergone reoperation from January 1993 to May 2017 were retrospectively analyzed. Results A total of 11 patients underwent reoperation were collected in the 226 patients with primary hyperparathyroidism. Of the 11 cases, 8 cases underwent twice operations, 2 cases underwent thrice operations, 1 case underwent quintic operation. After the initial operation, 3 cases were persistent diseases and 7 cases were recurrent diseases, 1 patient was not defined as the persistent or recurrent disease. The main clinical manifestations before the reoperation were fatigue, pain in joints, bones, or muscle. The reasons for reoperation included 3 cases of ectopic parathyroid lesions, 3 cases of recurrent parathyroid carcinomas, 1 case of enlarged operation extent for parathyroid carcinoma, 2 cases of regrowth of double parathyroid aedomas, 1 case of missing adenoma, 1 case of parathyroid hyperplasia. Among the location examinations, the 99Tcm-MIBI was most sensitivity (8/9). Eight cases were received reoperation on the original incision, and the remaining 3 ectopic parathyroid lesions on the new incision. After the reoperation, 2 patients were lost of follow-up, 1 patient died, and the remaining 8 patients had no recurrences during follow-up period. Conclusion A comprehensive approach with multiple imageology examinations which attribute to accurate location of lesions, experienced surgeons and well knowledge of parathyroid anatomy and embryology help to descend reoperation ratio and improve success rate of reoperation.
ObjectiveTo evaluate the clinical outcomes of pulmonary valve replacement (PVR) in patients with tetralogy of Fallot (TOF) after re-PVR surgery.MethodsPubMed, EMbase, the Cochrane Controlled Trials Register databases, CNKI, CBM disc and VIP datebases were searched, and study eligibility and data abstraction were determined independently and in duplicate. Literature searches from database establishment to December 2018. The heterogeneity and data were analyzed by the software of Stata 11.0.ResultsOf 4 831 studies identified, 26 studies met eligibility criteria, and invovled with a total of 3 613 patients. The combined 30-day mortality for PVR was 2.2% (95% CI 1.5%-3.1%) and follow-up mortality was 3.4% (95% CI 2.4%-4.9%), re-PVR rate was 6.8% (95% CI 5.1%-9.2%), and the rate of intervention was 11.4% (95% CI 8.0%-16.4%). Subgroup analysis showed that the patient's age range may be a heterogeneous source of mortality during the follow-up period, and there was no statistical heterogeneity for adult patients (P=0.63, I2=0%), with a lower incidence than those including adolescents patients. The type of valve was likely to be a source of retrospective PVR. There was no statistical heterogeneity in bioprosthetic valves and allograft lobes (P=0.24, I2=25%). And the incidence of re-PVR was lower than that of the mechanical valve patients. Heart function classification (NYHA) of patients with TOF after PVR was statistically improved (P<0.05). Electrocardiogram QRS change was not statistically differently (P>0.05). Postoperative MRI findings showed a decrease in RVEDV, an increase in RVEF, a decrease in RV/LV ratio, and a decrease in pulmonary valve (all P<0.05). Funnel map monitoring, Begg test and Egger's test both indicated that there was no publication bias.ConclusionsAccording to the results of the analysis, PVR after TOF surgery is a more mature surgery, the clinical effect was significant, with lower early and long-term mortality. The long-term mortality rate of adolescent patients undergoing PVR is higher than that of adult patients. Long-term outocme of re-PVR or re-intervention is still the main problem affecting the effect of the operation. Indications for surgery and choice of valve need further investigation.
Objective To explore prognostic factors of unplanned reoperation in Department of General Surgery. Methods The clinical data of 85 patients with unplanned reoperations who treated in the Northern District of the Shanghai Ninth People’s Hospital from January 2014 to May 2017 were retrospectively collected. The risk factors such as preoperative basic information, surgical related information, and postoperative information for death of unplanned reoperations were analyzed. Results There were 72 cured patients and 12 deaths in the 85 patients. The univariate analysis results showed that the age was older (P<0.05), the operative time was longer (P<0.05) in the patients with death as compared with the cured patients; the with basic diseases, selective operation, high grade of ASA, preoperative hemoglobin <90 g/L, admission to ICU after unplanned reoperations, postoperative complications, and multiple reoperations were correlated with the mortality of unplanned reoperations (P<0.05). The multivariate analysis results showed that the elderly patients, preoperative hemoglobin <90 g/L, and postoperative complications were the independent prognostic factors (P<0.05). The satisfaction of patients at discharge in the death group was significantly lower than that in the survival group (P<0.05). Conclusion Ederly patient, preoperative hemoglobin <90 g/L, and postoperative complications are independent prognostic factors of unplanned reoperations in Department of General Surgery.
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 summarize the surgical strategy of reoperative aortic root replacement after prior aortic valve replacement (AVR), and analyze the early and mid-term outcomes.MethodsFrom April 2013 to January 2020, 75 patients with prior AVR underwent reoperative aortic root replacement in Fuwai Hospital. There were 54 males and 21 females with a mean age of 56.4±12.7 years. An emergent operation was performed in 14 patients and an elective operation in 61 patients. The indications were aortic root aneurysm in 38 patients, aortic dissection involving aortic root in 30 patients, root false aneurysm in 2 patients, prosthesis valve endocarditis with root abscess in 2 patients, and Beh?et's disease with root destruction in 3 patients. The survival and freedom from aortic events during the follow-up were evaluated with the Kaplan-Meier survival curve and the log-rank test.ResultsThe operative procedures included prosthesis-sparing root replacement in 45 patients, Bentall procedure in 26 patients, and Cabrol procedure in 4 patients. Operative mortality was 1.3% (1/75). A composite of adverse events occurred in 5 patients, including operative death (n=1), stroke (n=1), and acute renal injury necessitating hemodialysis (n=3). The follow-up was available for all 74 survivors, with the mean follow-up time of 0.5-92.0 (30.3±25.0) months. Four late deaths occurred during the follow-up. The survival rate at 1 year, 3 years and 6 years was 97.2%, 91.4% and 84.4%, respectively. Aortic events developed in 2 patients. The rate of freedom from aortic events at 1 year, 3 years, and 6 years was 98.7%, 95.0% and 87.7%, respectively. There was no difference in rate of survival or freedom from aortic events between the elective patients and the emergent patients.ConclusionReoperative aortic root replacement after prior AVR can be performed to treat the root pathologies after AVR, with acceptable early and mid-term outcomes.
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 compare the postoperative outcomes of modified single-patch technique and one-and-a-half-patch technique for complete atrioventricular septal defect (CAVSD) with a large ventricular component (>1 cm). Methods We retrospectively reviewed clinical data of 79 CAVSD patients with a large ventricular component (>1 cm) in Shanghai Children's Medical Center from January 2005 through January 2016. There were 37 males, 42 females with a median age of 8 months (range, 1.5 months to 10.2 years). Among the patients, 45 patients (20 males, 25 females) with a median age of 6 months(range, 1.5 months to 10.2 years) received modified single patch technique and 34 patients (17 males, 17 females) with a median age of 5.3 months (range, 2.5 months to 8.3 years) underwent one-and-a-half-patch (1.5-patch) technique. All the patients complicated with complex malformation such as double outlet of right ventricular, single ventricle, and transposition of great arteries were excluded. Results The mortality and reoperation rate in modified single-patch group were higher than those of the one-and-a-half-patch group. There were 2 postoperative early deaths in the modified single-patch group (4.4%). Among them, one patient died of postoperative valvular regurgitation and heart pump failure. The other one died of respiratory failure caused by severe pneumonia. There were 3 reoperations. Two patients performed valve plastic surgery because of valve regurgitation and one patient because of residual ventricular septal defect. There was no death and reoperation in the one-and-a-half-patch technique group. No left ventricular outflow tract obstruction and atrioventricular block in both groups were developed. Conclusion The 1.5-patch technique is an attractive clinical option in CAVSD patients with a large ventricular component.
ObjectiveTo understand the current progress of diagnosis and treatment of accidental gallbladder cancer.MethodThe relevant literatures about diagnosis and treatment of accidental gallbladder cancer and gallbladder cancer were analyzed and summarized.ResultsDue to the lack of specific symptoms and signs in most patients with accidental gallbladder cancer at the early stage, appropriate imaging examinations and tumor marker examinations could improve the preoperative diagnosis rate. The radical resection was the most effective method for accidental gallbladder cancer, but there were still some controversies about the scope of resection according to different tumor stages, the choice of laparoscopic cholecystectomy or open cholecystectomy, and the timing of reoperation. The postoperative adjuvant therapy could improve the prognosis of patients, but most patients didn’t receive adjuvant therapy after surgery.ConclusionsMost patients with accidental gallbladder cancer are in the early stage, and most of them could obtain radical resection. If the first operation fails to achieve radical resection or postoperative pathological examination to confirm the diagnosis, comprehensive evaluation of the tumor stage and the patient’s general condition should be performed, and remedial treatment should be taken as soon as possible.
