Objective To summarize the clinical characteristics of laparoscopic unexpected gallbladder cancer (UGC), and to explore the impact of TNM stage and secondary surgery timing on postoperative survival. Methods Clinical data of 70 UGC patients who treated in Xianyang Hospital of Yanan University and The First Affiliated Hospital of Xi’an Jiaotong University from January 2008 to January 2014 were retrospectively analyzed. The influencing of TNM staging and secondary surgery timing on the prognosis of UGC patients were analyzed by single factor analysis. Results Of the 70 patients before operation, 68 patients (97.2%) were diagnosed as calculus of gallbladder, 1 patient (1.4%) was diagnosed as gallbladder polyps, 1 patient (1.4%) was diagnosed as intrahepatic and extrahepatic bile duct stone. TNM staging: 2 patients (2.9%) in stage 0, 9 patients (12.9%) in stage Ⅰ, 50 patients (71.4%) in stage Ⅱ, 6 patients (8.6%) in stage Ⅲa, 1 patient (1.4%) in stage Ⅲb, 1 patient (1.4%) in stage Ⅳa, and 1 patient (1.4%) in stage Ⅳb. Fifty-five patients (78.6%) were confirmed by intraoperative frozen section examination, and 15 patients (21.4%) were confirmed after laparoscopic surgery. There were 66 patients were followed-up for 2-79 months, and the median follow-up time was 28-month, the 1-， 3-, and 5-year survival rates were 92.3%, 70.7%, and 53.7% respectively. The survival curves of stage 0, Ⅰ, Ⅱ, and Ⅲ+Ⅳ were differed significantly (P ＜0.01), the survival situation was best in patients in stage 0 and Ⅰ, but worst in patients in stage Ⅲ+Ⅳ. There was no statistical difference between the prognosis of patients underwent one-stage surgery and those underwent two-stage surgery (P=0.73). Conclusions A large proportion of UGC are in stage Ⅱ. For UGC patients, the prognosis is related with the clinical stage, so the surgical approach does not worsen the prognosis, regardless whether the tumor is detected during or after laparoscopic cholecystectomy.

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.
ObjectiveTo evaluate feasibility of laparoscopic radical resection and re-resection for suspicious and incidental gallbladder cancer.MethodsWe searched PubMed and other databases, reviewed relevant literatures and summarized from aspects like whether efficacy comparable to laparotomy and enough lymph node dissection could be achieved through laparoscopy, timing of reoperation for incidental gallbladder cancer.ResultsLaparoscopic radical resection and re-resection were theoretically and technically feasible, but its efficacy and timing of re-resection were controversial, and its long-term efficacy needed further discussions in multi-center and large-scale cohort studies.ConclusionsLaparoscopy shows prospects of resection and re-resection for suspicious and incidental gallbladder cancer. Tentative explorations could be done in properly selected patients by well-experience medical centers and to achieve efficacy comparable to laparotomy is the fundamental principle.
ObjectiveTo explore the operative strategy after palliative shunt for correcting congenitally corrected transposition of great artery (cTGA) patients with left ventricular outflow tract obstruction (LVOTO) and cardiac malpostion.MethodsWe retrospectively analyzed the clinical data of 54 patients with onsecutive cTGA with LVOTO and cardiac malpositon from June 2011 to May 2019. The patients were devided into two groups. There were 24 patients (16 males and 8 females at mean age of 5.4±2.2 years) who underwent one and a half ventricle repair as a one and half ventricle group. And there were 30 patients (19 males and 11 females at age of 8.6±6.2 years) who underwent one ventricle repair operation as a one ventricle group. Follow-up data were collected by telephone interviews.ResultsThere was no statistical difference in systemic atrioventricular valve regurgitation and systemic ventricular ejection fraction between the two groups (P>0.05). Compared with one and a half ventricle group, the cardiopulmonary bypass time (CPB) time, mechanical ventilation time and intensive care unit stay were significant shorter than those in the one ventricle group (P<0.05), but prolonged pleural effusions developed more frequently in the one ventricle repair group (P<0.05). There was no in-hospital death but 1 follow-up death in each group. The follow-up time was 49 (17-38) months in the one and half ventricle group at follow-up rate of 93.9%, and 47 (12-85) months at follow-up rate at 90.9% in the one ventricle group. One and a half ventricle group had better systemic ventricular ejection fraction (EF) than that in the one ventricle repair group. And the rate of heart function (NYHA) class Ⅲ and class Ⅳ in one and a half ventricle group was lower than that in the ventricle group. No significant difference of survival and freedom from re-intervention probability between the two groups was found.ConclusionFor patients of correction of cTGA with LVOTO and cardiac malposition after palliative shunt, the one-and-a-half ventricular repair procedure is ideal operative strategy.
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.
Objective This study aimed to explore the experience of secondary excision for retrorectal cystic lesions. Method We retrospectively reviewed the medical records of patients who underwent secondary laparoscopic excision of retrorectal cystic lesions at the Department of General Surgery at our hospital between August 2012 and August 2021. Results Twelve patients [male: 5; female: 7; age: (31.8±11.5) years old (18–60 years old)] were evaluated. The lesions ranged from 5.8 to 15.0 cm in diameter [(10.0±3.5) cm]. Seven patients had epidermoid cysts, three patients had mature teratoma, one patient had mature teratoma with low-grade mucinous neoplasm and one patient had cyst with mucinous carcinoma. Laparoscopic excision of retrorectal cystic lesions was performed in ten patients, and laparoscopy combined transsacrococcygeal approach was performed in two patients. The median operative time was 137.5 min (80–240 min), and the median blood loss was 30 mL (10–200 mL). No patient experienced complications of Clavien-Dindo grade Ⅲa or worse, one patient experienced complications of Clavien-Dindo grade Ⅱa after operation. The mean duration of hospitalization was (5.9±1.4) d (3–7 d). The follow-up period ranged from 3 to 108 months, and the median follow-up time was 43-month, and one patient recurred during the follow-up period. Conclusions Attention should be paid to the initial diagnosis and treatment of retrorectal cystic lesions, particularly in children. Routine evaluation using preoperative pelvic MRI and the adoption of an appropriate surgical approach are recommended to reduce secondary operations. Surgery should be performed by surgeons experienced in rectal andpelvic surgeries.
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 Behçet'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.
