ObjectiveTo evaluate short-term clinical outcomes of skeletonized bilateral internal mammary artery (sBIMA) in coronary artery bypass grafting (CABG).MethodsThe clinical data of 62 patients (54 males and 8 females with an average age of 56.8±6.0 years) undergoing isolated CABG using sBIMA in our hospital from October 2016 to May 2017 were retrospectively analyzed. The coronary graft flow, perioperative clinical outcomes and CT results were reviewed.ResultsAll the operations were carried out under extracorporeal circulation. Anastomosis of 124 internal mammary arteries was performed and 116 great saphenous veins were used simultaneously with an average anastomosis site of 4.5±0.8 for each patient. The cardiopulmonary bypass time was 116.4±22.9 min, aortic clamping time was 83.0±18.3 min, mechanical ventilation time was 20.8±21.3 h and ICU stay was 2.7±1.7 d. The graft flow of left internal mammary artery (LIMA), right internal mammary artery (RIMA) and great saphenous vein were 28.8±12.4 mL/min, 32.8±13.8 mL/min and 41.5±21.5 mL/min, respectively. There was no significant difference in the graft flow between LIMA and RIMA (P=0.112). There was no perioperative mortality, myocardial infarction or cerebrovascular accident. Only one male patient suffered sternal complication and poor wound healing and then received debridement as well as suturing. Coronary CT angiography showed that distal anastomosis of 7 vein grafts and 5 artery grafts was demonstrated shallow and 1 vein graft was undemonstrated, suggesting occlusion.ConclusionCABG with sBIMA is a safe and reliable technique with excellent early results.
Objective To assess the safety and clinical outcomes of segmentectomy in one- or two-staged video-assisted thoracoscopic surgery (VATS) for bilateral lung cancer. MethodsWe retrospectively enrolled 100 patients who underwent VATS segmentectomy for bilateral lung cancer at the Department of Thoracic Surgery of Peking Union Medical College Hospital from December 2013 to May 2022. We divided the patients into two groups: a one-stage group (52 patients), including 17 males and 35 females with a mean age of 55.17±11.09 years, and a two-stage group (48 patients), including 16 males and 32 females with a mean age of 59.88±11.48 years. We analyzed multiple intraoperative variables and postoperative outcomes. Results All 100 patients successfully completed bilateral VATS, and at least unilateral lung received anatomical segmentectomy. Patients in the one-stage group were younger (P=0.040), had lower rate of comorbidities (P=0.030), were less likely to have a family history of lung cancer (P=0.018), and had a shorter interval between diagnosis and surgery (P=0.000) compared with patients in the two-stage group. Wedge resection on the opposite side was more common in the one-stage group (P=0.000), while lobectomy was more common in the two-stage group. The time to emerge from anesthesia in the one-stage group was longer than that in the first and second operations of the two-stage group (P=0.000, P=0.002). Duration of surgery and anesthesia were similar between two groups (P>0.05). Total number of lymph node stations for sampling and dissection (P=0.041) and lymph nodes involved (P=0.026) were less in the one-stage group. Intraoperative airway management was similar between two groups (P>0.05). The one-stage group was associated with lower activities of daily living (ADL) scores. Conclusion Segmentectomy is safe in one- or two-staged VATS for bilateral lung cancer, including contralateral sublobectomy and lobectomy. Duration of surgery and perioperative complications are similar between two groups, but the one-stage group is associated with lower ADL scores. On the basis of comprehensive consideration in psychological factors, physical conditions and personal wishes of patients, one-staged sequential bilateral VATS can be the first choice.
ObjectiveTo explore the ultrasonographic and pathological manifestations of primary bilateral breast cancer (PBBC).
MethodsThe ultrasonographic and clinical manifestations of 24 patients with PBBC confirmed by surgical pathology and clinical examination between January 2001 and April 2009 were studied retrospectively. The study contained 9 bilateral synchronous breast cancer patients aged from 41 to 60 years old, averaging 47.3 years, and 15 bilateral asynchronous breast cancer patients. For patients with bilateral asynchronous breast cancer, the age on the first lesion diagnosis was between 33 to 61 years with an average of 43.2; the age on the second lesion diagnosis was from 38 to 69 years old averaging 49.1; and the interval time between the first and second lesion diagnosis was from 3 to 8 years, averaging 5.9 years.
ResultsThe site of PBBC was more located in upper outer quadrant. Most lesions had obscure boundary, irregular shape, and heterogeneous internal echo in ultrasonographic manifestation. The vertical and horizontal diameter ratio > 1, acoustic shadowing, and microcalcification occurred in some of the lesions. The bloodstream of the lesions were mainly Adler gradeⅡorⅢ.
ConclusionsMost PBBC has typical ultrasonographic manifestations. The follow-up of PBBC patients should be based on imaging such as ultrasonography. The biopsy guided by ultrasonography can elevate the detection rate of PBBC.
Objective To design the surgical strategy of percutaneous full-endoscopic bilateral decompression via unilateral posterior approach for bilateral lumbar spinal stenosis (LSS) and to evaluate the effectiveness. Methods The percutaneous full-endoscopic bilateral decompression via unilateral posterior approach for bilateral LSS was designed according to the pathological features of LSS. The technique was used to treat 42 patients with LSS between January 2016 and January 2018. There were 18 males and 24 females with an average age of 61.7 years (range, 46-81 years). The duration of symptoms was 1-20 years, with an average of 9.7 years. The surgical segment at L4, 5 were 27 cases, at L5, S1 were 15 cases. The operation time and perioperative complications were recorded. Lumbar X-ray, CT, and MRI examinations were performed at 1 week, 3 months, and 1 year after operation. Visual analogue scale (VAS) score was used to evaluate the low back pain and leg pain, Oswestry disability index (ODI) was used to evaluate the lumbar function, and single continuous walking distance (SCWD) was used to evaluate lower extremity nerve function. The clinical efficacy was evaluated by MacNab criteria at 1 year after operation. Results All patients underwent surgery successfully. The operation time was 68-141 minutes with an average of 98.2 minutes. All 42 patients were followed up 12-24 months with an average of 18.8 months. There were 2 cases of dural tears during operation, and 1 case of transient dysfunction of the lower limbs of the decompression channel after operation. All of them were cured after corresponding treatment. No serious complications such as death, major bleeding, or irreversible nerve injury occurred during follow-up. No segmental instability was found according to postoperative lumbar hyperextension and flexion X-ray films, and postoperative CT and MRI imaging showed that the stenotic lumbar spinal canal was significantly enlarged, and the compression of the nerve root was sufficient. The VAS score of low back pain and leg pain, ODI score, and SCWD at each time point after operation were significantly improved when compared with those before operation (P<0.05); the indexes were significantly improved over time after operation, and the differences were significantly (P<0.05). The clinical efficacy was evaluated by MacNab standard at 1 year after operation, and the results were excellent in 18 cases, good in 20 cases, fair in 3 cases, and poor in 1 case. The excellent and good rate was 90.5%. Conclusion The percutaneous full-endoscopic bilateral decompression via unilateral posterior approach for LSS is a safe and effective procedure. A well-designed surgical strategy and mastery of its technical points are important guarantees for successful operation and satisfactory results.
ObjectiveTo investigate the effect of optimized arterial perfusion strategy on total arch replacement for acute type A aortic dissection (AAAD) with malperfusion syndrome (MPS).MethodsFrom 2017 to 2019, 51 patients with AAAD and MPS who had received total arch replacement with optimized arterial perfusion strategy in our hospital were included in the optimized perfusion group, including 40 males and 11 females, with an average age of 47.43±13.39 years. A total of 40 patients with AAAD and MPS who had been treated with traditional Sun's surgery were taken as the traditional control group, including 31 males and 9 females, with an average age of 50.66±12.05 years. The perioperative clinical data of the two groups were compared.ResultsThe preoperative baseline data of the two groups were basically consistent (P>0.05). The comparison of operative data between the optimized perfusion group and the traditional control group showed that in the optimized perfusion group, the extracorporeal circulation time, aortic occlusion time, and circulation-out cerebral perfusion time were significantly less than those in the traditional control group (223.64±65.13 min vs. 266.77±87.04 min, 114.48±27.28 min vs. 138.20±39.89 min, 8.28±3.81 min vs. 50.53±23.60 min, all P≤0.05). The lowest intraoperative nasopharyngeal temperature in the optimized perfusion group was significantly higher than that in the traditional control group (27.10±1.18℃ vs. 23.6±3.30℃, P=0.000). Postoperative wakefulness time of the optimized perfusion group was earlier than that of the traditional control group (4.50±1.35 h vs. 5.27±1.15 h, P=0.019). The volume of blood transfusions in the optimized perfusion group was significantly less than that in the traditional control group (13.25±9.06 U vs. 16.95±7.53 U, P=0.046). There was no significant difference in ICU time and invasive ventilation time between the two groups (P>0.05). Postoperative complications of the two groups showed that the incidence of postoperative continuous renal replacement therapy in the optimized perfusion group was significantly lower than that in the traditional control group, with a statistically significant difference (21.6% vs. 42.5% P=0.003). The incidence of postoperative delirium, coma, low cardiac row syndrome and limb ischemia in the optimized perfusion group was lower than that in the traditional control group, but the difference was not statistically significant (P>0.05). The incidence of postoperative hemiplegia, sepsis, and secondary thoracotomy in the optimized perfusion group was higher than that in the traditional control group, and the difference was not statistically significant (P>0.05). Postoperative mortality in the optimized perfusion group was significantly lower than that in the traditional control group (13.7% vs. 27.5%), but the difference was not statistically significant (P=0.102).ConclusionOptimized arterial perfusion strategy and its related comprehensive surgical technique reduce surgical trauma, shorten the operation time, reduce perioperative consumption of blood products. Postoperative wakefulness is rapid and the incidence of complications of nervous system, kidney and limb ischemia is low. Optimized arterial perfusion strategy is suitable for operation of AAAD with MPS by inhibiting the related potential death risk factors to reduce operation mortality.
Objective
To compare the effectiveness between unilateral and bilateral percutaneous kyphoplasty (PKP) in the treatment of Kümmell disease.
Methods
The clinical data of 45 patients with Kümmell disease that met the criteria between January 2014 and February 2016 were analyzed retrospectively. Among them, 26 cases were treated by unilateral PKP (unilateral group), 19 cases were treated by bilateral PKP (bilateral group). There was no significant difference in gender, age, disease duration, injured vertebral segment, bone mineral density (T value), and the preoperative visual analogue scale (VAS) score, Oswestry disability index (ODI), anterior vertebral height, and kyphosis Cobb angle between 2 groups (P>0.05). The operation time, intraoperative fluoroscopy times, amount of injected bone cement, and hospitalization time were recorded, and the situation of bone cement leakage was observed. The VAS score, ODI, anterior vertebral height, and kyphosis Cobb angle were evaluated before operation, at 1 day after operation, and at last follow-up.
Results
Bone cement leakage during the operation were found in 4 cases (15.38%) of unilateral group and 3 cases (15.79%) of bilateral group without obvious neurological symptoms; there was no significant difference in the incidence of bone cement leakage between 2 groups (χ2=0.000, P=1.000). The operation time, intraoperative fluoroscopy times, and amount of injected bone cement in the unilateral group were significantly lower than those in the bilateral group (P<0.05); but there was no significant difference in the hospitalization time between 2 groups (P>0.05). The X-ray film examination showed that there was no pulmonary embolism in all patients at 1 day after operation. All the patients were followed up 12-24 months, with an average of 16.4 months. There was no complication such as vertebral re-fracture or cement block displacement in the injured vertebra. The VAS score, ODI, anterior vertebral height, and kyphosis Cobb angle at 1 day after operation and at last follow-up were significantly improved when compared with preoperative values in 2 groups (P<0.05); the VAS score and ODI in 2 groups were further reduced at last follow-up when compared with the value at 1 day after operation (P<0.05), but the anterior vertebral height and kyphosis Cobb angle in 2 groups at last follow-up did not change significantly (P>0.05). There was no significant difference in above indexes at 1 day after operation and at last follow-up between 2 groups (P>0.05).
Conclusion
Both unilateral and bilateral PKP can achieve good effectiveness in treatment of Kümmell disease. But the unilateral puncture technique possesses advantages such as shorter operation time, less radiation dose, and less amount of injected bone cement.
Objective To investigate the effects of different puncture levels on bone cement distribution and effectiveness in bilateral percutaneous vertebroplasty for osteoporotic thoracolumbar compression fractures. Methods A clinical data of 274 patients with osteoporotic thoracolumbar compression fractures who met the selection criteria between December 2017 and December 2020 was retrospectively analyzed. All patients underwent bilateral percutaneous vertebroplasty. During operation, the final position of the puncture needle tip reached was observed by C-arm X-ray machine. And 118 cases of bilateral puncture needle tips were at the same level (group A); 156 cases of bilateral puncture needle tips were at different levels (group B), of which 87 cases were at the upper 1/3 layer and the lower 1/3 layer respectively (group B1), and 69 cases were at the adjacent levels (group B2). There was no significant difference in gender, age, fracture segment, degree of osteoporosis, disease duration, and preoperative visual analogue scale (VAS) score, and Oswestry disability index (ODI) between groups A and B and among groups A, B1, and B2 (P>0.05). The operation time, bone cement injection volume, postoperative VAS score, ODI, and bone cement distribution were compared among the groups. Results All operations were successfully completed without pulmonary embolism, needle tract infection, or nerve compression caused by bone cement leakage. There was no significant difference in operation time and bone cement injection volume between groups A and B or among groups A, B1, and B2 (P>0.05). All patients were followed up 3-32 months, with an average of 7.8 months. There was no significant difference in follow-up time between groups A and B and among groups A, B1, and B2 (P>0.05). At 3 days after operation and last follow-up, VAS score and ODI were significantly lower in group B than in group A (P<0.05), in groups B1 and B2 than in group A (P<0.05), and in group B1 than in group B2 (P<0.05). Imaging review showed that the distribution of bone cement in the coronal midline of injured vertebrae was significantly better in group B than in group A (P<0.05), in groups B1 and B2 than in group A (P<0.05), and in group B1 than in group B2 (P<0.05). In group A, 7 cases had postoperative vertebral collapse and 8 cases had other vertebral fractures. In group B, only 1 case had postoperative vertebral collapse during follow-up. ConclusionBilateral percutaneous vertebroplasty in the treatment of osteoporotic thoracolumbar compression fractures can obtain good bone cement distribution and effectiveness when the puncture needle tips locate at different levels during operation. When the puncture needle tips locate at the upper 1/3 layer and the lower 1/3 layer of the vertebral body, respectively, the puncture sites are closer to the upper and lower endplates, and the injected bone cement is easier to connect with the upper and lower endplates.
Objective
To share the experience of single-stage bilateral pulmonary resections by video-assisted thoracic surgery (VATS) for multiple nodules.
Methods
Clinical records of patients undergoing one-stage bilateral resections of multiple pulmonary nodules between January 2015 and December 2016 in our institution were retrospectively reviewed and analyzed. There were 9 males and 15 females, aged from 33 to 69 (55.0±8.0) years. Two patients underwent bilateral lobectomy. Lobar-sublobar (L/SL) resection and bilateral sublobar resection (SL-SL) were conducted in 9 patients and 13 patients respectively.
Results
All operations completed successfully. Operation time was 135–330 (231.4±59.1) min, duration of use of chest drains was 2–17 (5.4±3.1) days. Overall duration of hospitalization after surgery was 5–37 (8.6±6.3) days. There was no perioperative death. Postoperative course was uneventful in 17 (70.8%) patients. The postoperative complications included one patient of incision infection and one patient of pulmonary infection. Persistent air leak for >3 days duration and unilateral pleural drainage for more than 200 ml/d were observed in 3 patients and 2 patients respectively.
Conclusion
Single-stage bilateral surgery in selected patients with synchronous bilateral multiple nodules is feasible and associated with satisfactory outcomes.
ObjectiveTo introduce the method and preliminary experience of robot-assisted bilateral internal mammary arteries (BIMA) harvesting for off-pump coronary artery bypass grafting (OPCAB) with 5 grafts via left anterolateral minithoracotomy.MethodsBIMA were harvested using the da Vinci robotic surgical system, and the right internal mammary artery (RIMA) was pulled out of the thoracic cavity through right second intercostal space. Intercepting the distal part of the RIMA for the BIMA composite Lima-Rima Y graft and anastomosing the great saphenous vein with remaining RIMA end to end. The Y graft anastomosed with left anterior descending (LAD) branch and diagonal branches (DIAG), artery-vein graft sequentially anastomosed with blunt round branch, left ventricular posterior branch and posterior descending branch.ResultsThe operation succeeded without hemodynamic instability and intra aortic balloon pump (IABP) implantation or cardiopulmonary bypass. The blood flow of Y graft was 24 mL/min, and the blood flow of artery-vein graft was 30 mL/min. Ventilator assistance time was 35 hours, ICU staying time was 62 hours, and postoperative myocardial enzymes increased temporarily. Postoperative coronary CTA showed that all the grafts were patency, and cardiac ultrasound indicated that the heart function was normal. The patient cured and discharged from hospital 7 days after operation.ConclusionRobot-assisted bilateral internal mammary artery harvesting for OPCAB with 5 grafts via left anterolateral minithoracotomy is feasible, which can achieve complete revascularization.
