ObjectiveTo compare the perioperative outcomes between robot-assisted complex segmentectomy and simple segmentectomy for stage ⅠA non-small cell lung cancer (NSCLC). MethodsThe clinical data of 285 patients with NSCLC undergoing robot-assisted thoracic surgery (RATS) in our hospital from January 2015 to August 2021 were retrospectively analyzed. There were 105 males and 180 females aged 23-83 years. The patients were divided into a complex segmentectomy group (n=170) and a simple segmentectomy group (n=115) according to tumor location and surgical method. The clinical pathological baseline characteristics and perioperative outcomes between the two groups were compared, including operative time, blood loss volume, dissected lymph nodes, conversion rate, postoperative duration of drainage, postoperative hospital stay, the incidence of persistent air leakage and postoperative 30 d mortality. ResultsThere was no statistical difference in baseline data between the two groups (P>0.05). No postoperative 30 d death was observed. One patient in the complex segmentectomy group was transferred to thoracotomy. No statistical difference was observed between the two groups in the operative time (97.36±38.16 min vs. 94.65±31.67 min, P=0.515), postoperative duration of drainage (3.69±1.85 d vs. 3.60±1.90 d, P=0.679), postoperative hospital stay (4.07±1.85 d vs. 4.05±1.97 d, P=0.957), dissected lymph nodes (5.15±3.53 vs. 5.13±2.93, P=0.952), incidence of blood loss volume<100 mL (98.2% vs. 99.1%, P=0.650), and incidence of postoperative persistent air leakage (6.5% vs. 5.2%, P=0.661). ConclusionThe safety and effectiveness of robot-assisted complex segmentectomy and simple segmentectomy are satisfactory in the treatment of stage ⅠA NSCLC. The perioperative results of RATS complex segmentectomy and simple segmentectomy are similar.
Abstract:Objective To summarize the experiences of single stage repair of interrupted aortic arch （IAA） associated with cardiac anomalies. Methods From Jan. 2000 to Dec. 2005, 48 patients admited in hospital and 35 patients were operated, the mean age at operation was 1.1 years. The associated anomalies included 23 cases of ventricular septal defect, 2 cases of transposition of great arteries, 3 cases of aortopulmonary window with aortic origin of right pulmonary artery, 2 cases of truncus arteriosus, 2 cases of double outlet right ventricle, 2 cases of stenotic fifth arch and 1 case of aberrant origin of right subclavian artery with mild hypoplastic decending aorta. Among them, 34 patients underwent single stage repair and 1 kid underwent palliative correction. Results There were 4 surgical deaths. The sequelae included one diaphragm paralysis and one 3rd degree of atrioventricular block. Only 5 kids recurred mild stenosis of aortic arch anastomosis and 2 death occurred during 3 months to 4 years of follow-up. Conclusion Though early surgical mortality for primary single stage repair is now relatively low, if appropriate interventions has been accomplished during perioperative period, but outcomes of IAA remain of concern, especially in patients with associated lesions.
ObjectiveTo compare the efficacy and safety of mitral valvuloplasty via minimally invasive approach with those of mitral valvuloplasty via traditional median sternotomy.MethodsA total of 1 221 patients undergoing mitral valvuloplasty from January 2015 to August 2018 in Guangdong Provincial People's Hospital were analyzed retrospectively, including 721 males and 500 females, with an average age of 47.2±15.1 years. According to the different surgical methods, they were divided into a study group (n=654), who received mitral valvuloplasty via the totally thoracoscopic approach, and a control group (n=567), who received mitral valvuloplasty via traditional median sternotomy. Clinical data, surgical results, and perioperative outcomes of the two groups were compared.ResultsThere was no significant difference in preoperative general data between the two groups (P>0.05). Compared with the control group, the study group had longer cardiopulmonary bypass time and aortic cross-clamping time (146.7±42.4 min vs. 122.7±30.6 min, 96.2±32.7 min vs. 78.3±23.8 min, both P=0.000), and shorter total operation time (227.4±55.3 min vs. 238.1±56.4 min, P=0.001). There was no significant difference in the incidence of secondary cross-clamping and mitral valve replacement between the two groups (3.7% vs. 2.6%, P=0.312; 1.7% vs. 1.4%, P=0.690). The blood transfusion rate and the incidence of respiratory tract infection and postoperative poor wound healing were lower (13.0% vs. 24.5%, 2.1% vs. 18.0%, 1.5% vs. 5.3%, all P=0.000) and the postoperative hospital stay was shorter (6.2±4.4 d vs. 11.5±8.8 d, P=0.000) in the study group. There was no significant difference in hospitalization expense between the two groups (95 847.9±31 322.0 yuan vs. 99 673.1±47 930.3 yuan, P=0.149). Within 30 d after surgery, 1 patient died in the study group and 4 patients died in the control group. Before discharge, there were 4 and 5 patients with severe mitral valve regurgitation in the study group and the control group, respectively.ConclusionCompared with mitral valvuloplasty via traditional median sternotomy, minimally invasive mitral valvuloplasty is superior in shortening operation time and postoperative hospital stay, lowering blood transfusion rate, and reducing postoperative complications, which can achieve better clinical outcomes.
Objective To understand the changes of intestinal flora during perioperative period of colorectal cancer and the mechanism affecting the occurrence of postoperative anastomotic leakage, so as to improve perioperative management of patients and find possible measures to decrease the incidence rate of anastomotic leakage. Method The literature related to perioperative intestinal flora assessment, anastomotic healing, and anastomotic leakage of colorectal cancer in recent years was comprehensively searched in the CNKI, PubMed, and Embase databases and made an review. ResultsDue to the various perioperative interventions, the diversity and abundance of intestinal flora had changed after colorectal cancer surgery, and some conditional pathogenic bacteria such as Enterococcus faecalis, Pseudomonas aeruginosa, etc. increased obviously, which led to collagen degradation through the expression of bacterial collagenase or the excessive activation of matrix metalloproteinases in the host intestine, then might lead to the poor anastomotic healing and even the anastomotic leakage. ConclusionAlthough the evidence of effect of intestinal flora on anastomotic leakage mainly comes from animal experiments, it still shows the potential role of intestinal flora in the occurrence of anastomotic leakage after colorectal cancer surgery, and can be regulated by perioperative intervention, which suggests that it may provide a new strategy for prevention of anastomotic leakage.
ObjectiveTo explore the postoperative characteristics and management experience of patients with coronavirus disease 2019 (COVID-19) undergoing cardiac and vascular surgery. MethodsFrom December 7, 2022 to January 5, 2023, the patients with COVID-19 who were admitted to Cardiovascular Hospital Affiliated to Kunming Medical University and underwent cardiac and vascular surgery were selected. The clinical history, surgical information, postoperative recovery process and treatment plan were analyzed retrospectively. ResultsThere were 18 patients in this group, including 11 (61.1%) males and 7 (38.9%) females, with an average age of 58.1±10.9 years. There were 7 patients of hypertension, 5 patients of diabetes, 3 patients of respiratory diseases, and 2 patient of chronic renal insufficiency. There were 5 (27.8%) patients receiving emergency operations and 13 (72.2%) elective operations. All the 18 patients underwent cardiac and vascular surgery in the period of COVID-19, and the time between the last positive nucleic acid test and the surgery was 1.50 (1.00, 6.25) days. There were 8 patients of pulmonary imaging changes, including 3 patients with chest patch shadow, 3 patients with thickened and disordered lung markings, and 2 patients with exudative changes before operation. Antiviral therapy was not adopted in all patients before operation. Three patients were complicated with viral pneumonia after operation, including 2 patients with high risk factors before operation, who developed into severe pneumonia after operation, and underwent tracheotomy. One patient with thrombus recovered after anticoagulation treatment. Another patient of mild pneumonia recovered after antiviral treatment. The other 15 patients recovered well without major complications. There was no operation-related death in the whole group. One patient died after surgery, with a mortality rate of 5.6%. Conclusion Patients with COVID-19 are at high risk of cardiac and vascular surgery, and patients with high-risk factors may rapidly progress to severe pneumonia. Patients with preoperative lung imaging changes or other basic visceral diseases should consider delaying the operation. Early antiviral combined with immunomodulation treatment for emergency surgery patients may help improve the prognosis.
Objective To compare the perioperative outcomes of atypical segmentectomy between robotic-assisted thoracoscopic surgery (RATS) and conventional video-assisted thoracoscopic surgery (VATS) in early-stage non-small cell lung cancer (NSCLC). MethodsThe data of patients who underwent minimally invasive anatomic atypical segmentectomy in our hospital from October 2016 to December 2021 were collected. These patients were divided into a RATS group and a VATS group according to the operation method. Propensity score (PS) matching was used to select patients with close clinical baseline characteristics, and the perioperative results of the two groups were compared. ResultsA total of 1 048 patients were enrolled, including 320 males and 728 females, with a mean age of 53.51±11.13 years. There were 277 patients in the RATS group and 771 patients in the VATS group. After 1∶1 PS matching, 277 pairs were selected. Both groups were well balanced for age, sex, smoking history, body mass index, Charlson comorbidity index, pulmonary function, tumor size, tumor location, and histological type. All patients were R0 resection, and there were no deaths within 30 days after surgery. The RATS group had shorter operative time [85 (75, 105) min vs. 115 (95, 140) min, P<0.001] and less blood loss [50 (30, 100) mL vs. 60 (50, 100) mL, P=0.001]. There were no statistical differences between the two groups in lymph node resection, conversion to thoracotomy, thoracic drainage time, total amount of thoracic drainage or postoperative complications (P>0.05). ConclusionBoth RATS and VATS atypical segmentectomies are safe and feasible for early-stage NSCLC. RATS can effectively shorten the operative time, and reduce blood loss.
With the continuous advancements in immunotherapy and targeted therapy, the treatment management and surgical resection assessment of locally advanced lung cancer have undergone significant changes. In October 2024, the Society of Thoracic Surgeons (STS) released the "STS expert consensus on the multidisciplinary management and resectability of locally advanced non-small cell lung cancer", which provides the latest insights on the evaluation of resectability and multidisciplinary management of locally advanced lung cancer, neoadjuvant (including perioperative) therapy, and adjuvant therapy. This article aims to interpret this consensus, with the goal of introducing the latest perspectives of the STS consensus to thoracic surgeons and providing a reference for the rational implementation of surgical resection, multidisciplinary management, and standardized comprehensive treatment models for non-small cell lung cancer in China.
