Objective To compare perioperative results between transventricular and transatrialtransventricular approaches in repairing tetralogy of Fallot (TOF), and to improve the surgical results. Methods The data of 1 423 consecutive patients who underwent complete repair of TOF between January 1998 and December 2007 were reviewed. 736 patients were repaired by the transventricular approach,and 687 patients by the transatrialtransventricular approach. Results Patients repaired by transventricular approach decreased from 100% in 1998 to 65% in 2002, and by transatrialtransventricular approach increased from 35% in 2002 to 79% in 2007. Aortic clamping time, cardiopulmonary bypass (CPB) time,mechanical ventilation time,and intensive care unit (ICU) stay in patients repaired by transatrialtransventricular approach had less than those in patients repaired by transventricular approach. No difference in transvalve patch ratio.There was lower morbidity in patients repaired by transatrialtransventricular approach in one to two organ systems dysfunction than that in patients repaired by transventricular approach. No difference in three or more organ systems dysfunction between them. Rate of residual ventricular septal defect(VSD), right ventricule to mean pulmonary artery (MPA) pressure gradient, tricuspid regurgitation, pulmonary artery regurgitation and arrhythmia in patients repaired by transatrialtransventricular approach were less than those in patients repaired by transventricular approach. Reoperative rate and mortality in patients repaired by transatrialtransventricular approach were less than those in patients repaired by transventricular approach. Conclusion TOF repair by the transatrialtransventricular approach fits to the actual conditions in China.
Objective To compare the clinical effects of two surgical approaches to treatment of horseshoe kidney.Methods From January 1965 to December 1982, 15 patients (11 males, 4 females; aged 14 months to 59 years with a median of 31 years) with horseshoe kidney underwent surgical treatment by the waist cretroperitoneal approach (the waist-approach group). The clinical symptoms and signs were as follows:pain in the waist and abdomen (12 patients), hematuria (7), urinary frequency (4), gastrointestinal disorder (3), and abdominal masses (2). The urography revealed urinary calculus in 10 patients, hydronephrosis in 3, renal cyst in 1, pyonephrosis in 1, renal tuberculosis in 1, and renal cell carcinoma in 1. From January 1977 to December 2005, 17patients (15 males, 2 females; aged 11 months to 56 years with a median of 29.4years) with horseshoe kidney underwent surgical treatment by the epigastric transperitoneal approach (theabdomenapproach group). The clinical symptoms and signs were as follows:pain in the waist and abdomen (15patients), hematuria (12), urinary frequency (10), gastrointestinal disorder (9), and abdominal masses (7). Theurography revealed urinary calculus in 12 patients, hydronephrosis in 10,renal cyst in 3, renal tuberculosis in 1, renal cell carcinoma in 1, and congenital spinal bifida in 1. The two surgical approaches were compared in the clinical therapeutic effects. Results There were no statistically significant differences in operating time, blood loss during operation, and the hospitalization after operation between the waistapproach group and the abdomen-approach group (129.59±23.25 min vs. 163.80±36.25min; 495.29±87.20ml vs. 553.00±92.27ml；13.17±1.14d vs. 13.75±0.21d; Pgt;0.05). Thepostoperative followup for 7 months to 6 years in 11 patients in the waistapproach group and in 6 patients in the abdomenapproach group revealed that there were statistically significant differences in postoperative complication and the recurrence rate of the renal calculus between the two groups (11.76%, 2/17 vs 26.67%, 4/15; 33.33%, 5/15 vs. 0, 0/17; Plt;0.05). The urography or CT taken 6 months to 2 years after operation in 4 patients in the waistapproach group and in 10 patients in the abdomenapproach group revealedthat there was a significant improvement hydronephrosis when compared with before operation.
ObjectiveTo evaluate the feasibility and clinical value of robot-assisted lung segmentectomy through anterior approach.MethodsWe retrospectively analyzed the clinical data of 77 patients who underwent robotic lung segmentectomy through anterior approach in our hospital between June 2018 to October 2019. There were 22 males and 55 females, aged 53 (30-71) years. Patients' symptoms, general conditions, preoperative imaging data, distribution of resected lung segments, operation time, bleeding volume, number of lymph node dissected, postoperative duration of chest tube insertion, drainage volume, postoperative hospital stay, postoperative complications, perioperative death and other indicators were analyzed.ResultsAll operations were successfully completed. There was no conversion to thoracotomy, serious complications or perioperative death. The postoperative pathology revealed early lung cancer in 48 patients, and benign tumors in 29 patients. The mean clinical parameters were following: the robot Docking time 1-30 (M=4) min, the operation time 30-170 (M=76) min, the blood loss 20-400 (M=30) mL, the drainage tube time 2-15 (M=4) days, the drainage fluid volume 200-3 980 (M=780) mL and the postoperative hospital time 3-19 (M=7) days.ConclusionRobotic lung segmentectomy through anterior approach is a safe and convenient operation method for pulmonary nodules.
