ABSTRACT

@#Objective To explore the reliability and safety of continuous monitoring of vital signs in patients using wireless wearable monitoring devices after video-assisted thoracoscopic surgery (VATS) for lung cancer. Methods The patients undergoing VATS for lung cancer in West China Hospital, Sichuan University from May to August 2023 were prospectively enrolled. Both wireless wearable and traditional wired devices were used to monitor the vital signs of patients after surgery. Spearman correlation analysis, paired sample t test and ratio Bland-Altman method were used to test the correlation, difference and consistency of monitoring data measured by the two devices. The effective monitoring rate of the wireless wearable device within 12 hours was calculated to test the reliability of its continuous monitoring. Results A total of 20 patients were enrolled, including 15 females and 5 males with an average age of 46.20±11.52 years. Data collected by the two monitoring devices were significantly correlated (P<0.001). Respiratory rate and blood oxygen saturation data collected by the two devices showed no statistical difference (P>0.05), while heart rate measured by wireless wearable device was slightly lower (=−0.307±1.073, P<0.001), and the blood pressure (=1.259±5.354, P<0.001) and body temperature(=0.115±0.231, P<0.001) were slightly higher. The mean ratios of heart rate, respiratory rate, blood oxygen saturation, blood pressure and body temperature collected by the two devices were 0.996, 1.004, 1.000, 1.014, and 1.003, respectively. The 95% limits of agreement (LoA) and 95% confidence interval of 95%LoA of each indicator were within the clinically acceptable limit. The effective monitoring rate of each vital signs within 12 hours was above 98%. Conclusion The wireless wearable device has a high accuracy and reliability for continuous monitoring vital signs of patients after VATS for lung cancer, which provides a security guarantee for subsequent large-scale clinical application and further research.

ABSTRACT

Objective: To summarize the clinical and genetic characteristics of children with β-ketothiolase deficiency (BKTD). Methods: The clinical characteristics, biochemical, markers detected by tandem mass spectrometry (MS/MS) and gas chromatography-mass spectrometry (GC/MS), as well as the variants in ACAT1 gene among 5 children with BKTD in Children's Hospital of Chongqing Medical University between October 2018 and December 2022 were retrospectively analyzed. Results: The onset age of the disease in 5 patients (4 males and 1 female) ranged from 9.7 to 28.0 months. During the acute phase, severe metabolic acidosis was observed with a pH of 6.9-7.1, as well as hypoglycaemia (2.3-3.4 mmol/L) and positive urinary ketone bodies (+-++++). Blood levels of methylcrotonyl carnitine, methylmalonyl carnitine and malonyl carnitine were 0.03-0.42, 0.34-1.43 and 0.83-3.53 μmol/L respectively and were significantly elevated. Urinary 2-methyl-3-hydroxybutyric acid was 22-202 and 3-hydroxybutyric acid was 4-6 066, both were higher than the normal levels. Methylcrotonylglycine was mild elevated (0-29). The metabolites detected by MS/MS and GC/MS were significantly reduced after treatment. Analysis of ACAT1 gene mutation was performed in 5 children. Most variants were missense (8/9). Four previously unreported variants were identified: c.678G>T (p.Trp226Cys), c.302A>G (p.Gln101Arg), c.627_629dupTGA (p.Asn209_Glu210insAsp) and c.316C>T (p.Gln106Ter), the first 2 variants were predicted to be damaging by SIFT, PolyPhen-2 and Mutation Taster software. c.316C>T (p.Gln106Ter) is a nonsense variant. Conclusions: β-ketothiolase deficiency is relatively rare, lacks specific clinical manifestations, however severe metabolic acidosis, hypoglycemia, and ketosis during the acute onset were consistent findings. Missense mutations in the ACAT1 gene are common genetic causes of β-ketothiolase deficiency.

ABSTRACT

@#The increasing number of pulmonary nodules being detected by computed tomography scans significantly increase the workload of the radiologists for scan interpretation. Limitations of traditional methods for differential diagnosis of pulmonary nodules have been increasingly prominent. Artificial intelligence (AI) has the potential to increase the efficiency of discrimination and invasiveness classification for pulmonary nodules and lead to effective nodule management. Chinese Experts Consensus on Artificial Intelligence Assisted Management for Pulmonary Nodule (2022 Version) has been officially released recently. This article closely follows the context, significance, core implications, and the impact of future AI-assisted management on the diagnosis and treatment of pulmonary nodules. It is hoped that through our joint efforts, we can promote the standardization of management for pulmonary nodules and strive to improve the long-term survival and postoperative life quality of patients with lung cancer.

ABSTRACT

@#Objective     To summarize the perioperative and long-term outcomes of ground-glass opacity (GGO) dominant early stage lung cancer patients treated by anatomic segmentectomy. Methods     We collected clinical data of 756 patients from Western China Lung Cancer Database, who underwent intentional anatomic segmentectomy [tumor size (T) ≤ 2 cm, GGO ≥ 50%] in the Department of Thoracic Surgery, West China Hospital, Sichuan University from 2009 to 2018. There were 233 males and 523 females at a median age of 53 (25-83) years including 290 (38.4%) patients of simple segmentectomy and 466 (61.6%) patients of complex segmentectomy. All patients were diagnosed as adenocarcinoma, including 338 (44.7%) patients of minimally invasive adenocarcinoma and 418 (55.3%) patients of invasive adenocarcinoma. Results     The median operative time was 115 (38-300) min, the median blood loss was 20 (5-800) mL, 58 (7.7%) patients had postoperative complications and the postoperative stay was 4 (2-24) days. The median follow-up period was 43.0 (30.1-167.9) months. Five-year overall survival rate was 99.5% [95%CI (98.8%, 100.0%)], 5-year recurrence-free survival rate was 98.8% [95%CI (97.5%, 100.0%)], and 5-year lung cancer-specific survival rate was 100.0%. Conclusion    Anatomic segmentectomy has favorable perioperative outcomes and excellent prognosis in GGO dominant early stage lung cancer patients.

ABSTRACT

@#Objective     To identify the risk factors for postoperative recurrence of peripheral solid small-nodule lung cancer (PSSNLC) (T≤2 cm), and to explore the effects of surgery types on prognosis. Methods     We extracted data from Western China Lung Cancer Database (WCLCD), a prospectively maintained database at the Department of Thoracic Surgery, West China Hospital, Sichuan University, and Surveillance, Epidemiology, and End Results (SEER)  database for peripheral solid small-nodule lung cancer patients (T≤2 cm N0M0, stageⅠ) who underwent surgery between 2005 and 2016. We used univariable and multivariable logistic regression to analyze risk factors for recurrence of PSSNLC. We applied propensity-score matching to compare the long-term results of segmentectomy and lobectomy, as well as the survival of patients from WCLCD and SEER. We finally included 4 800 patients with PSSNLC (T≤2 cm N0M0)(WCLCD: SEER=354∶4 446). We matched 103 segmentectomies and 350 lobectomies in T≤1 cm, and 280 segmentectomies and 1 067 lobectomies in 1 cm<T≤2 cm at a ratio of 1∶4 according to the propensity scores. Results     The results of multivariable logistic regression showed that older age (HR=1.04, 95%CI 1.03-1.05, P<0.001), male (HR=1.60, 95%CI 1.37-1.88, P<0.001), squamous carcinoma (HR=1.65, 95%CI 1.40-1.95, P<0.001), lymph node removed (HR=0.97, 95%CI 0.96-0.99, P<0.001) were risk factors for recurrence after surgery. We found that segmentectomy and lobectomy could reach similar survival in PSSNLC patient with either T≤1 cm or 1 cm<T≤2 cm. Analyses of 1 441 patients with PSSNLC after matching (WCLCD∶SEER=325∶1 116) indicated that the 5-year overall survival rate of the patients in WCLCD was better than that in SEER database ( 89.8% vs. 77.1%, P<0.001). Conclusion     Older age, male, squamous carcinoma, and lymph node removed are the risk factors for recurrence of PSSNLC. Segmentectomy shows similar survival in PSSNLC patient with either T≤1 cm or 1 cm<T≤2 cm N0M0. The patients in the WCLCD shows better survival compared with of the patients in the SEER database.

ABSTRACT

@#Objective     To analyze the perioperative outcomes of uniportal thoracoscopic lobectomy compared with three-port thoracoscopic lobectomy. Methods     Data were extracted from the Western China Lung Cancer Database, a prospectively maintained database at the Department of Thoracic Surgery, West China Hospital, Sichuan University. Perioperative outcomes of the patients who underwent uniportal or three-port thoracoscopic lobectomy for lung cancer during January 2014 through April 2021 were analyzed by using propensity score matching. Altogether 5 817 lung cancer patients were enrolled who underwent thoracoscopic lobectomy (uniportal: 530 patients; three-port: 5 287 patients). After matching, 529 patients of uniportal and 1 583 patients of three-port were included. There were 529 patients with 320 males and 209 females at median age of 58 (51, 65) years in the uniportal group and 1 583 patients with 915 males and 668 females at median age of 58 (51, 65) years in the three-port group. Results     Uniportal thoracoscopic lobectomy was associated with less intraoperative blood loss (20 mL vs. 30 mL, P<0.001), longer operative time (115 min vs. 105 min, P<0.001) than three-port thoracoscopic lobectomy. No significant difference was found between the two groups regarding the number of lymph node dissected, rate of conversion to thoracotomy, incidence of postoperative complication, postoperative pain score within 3 postoperative days, length of hospital stay, or hospitalization expenses. Conclusion     Uniportal video-assisted thoracoscopic lobectomy is safe and effective, and the overall perioperative outcomes are comparable between uniportal and three-port strategies, although the two groups show differences in intraoperative blood loss.

ABSTRACT

Objective@#To study the current development of thoracic surgery in China.@*Methods@#Chinese Society for Thoracic and Cardiovascular Surgery and Chinese Association for Thoracic Surgeons jointly conducted a network survey to directors of thoracic surgery departments in the tertiary hospitals in China from November to December 2018. The contents of the survey included the basic information of the hospital and the status of thoracic surgery department in the hospital. Rank sum test was used to compare the data between different regional hospitals@*Results@#A total of 636 tertiary hospitals participated in the survey. The total number of beds for thoracic surgery departments was 30 646, with M(QR) of 40(20) (range: 3 to 393) for each hospital. The total number of thoracic surgeons was 6 747, with M(QR) of 9(6) (range: 1 to 75) in each hospital. In 2015, a total of 312 425 operations were performed in the 636 hospitals, with M(QR) of 268(484.5) (range: 4 to 8 320) for each hospital. The total number of lung cancer surgeries was 146 601 in 2015, with M(QR) of 100(216) (range: 0 to 6 911) operations in each hospital. The total number of esophageal cancer operations was 67 076, with M(QR) of 40(95) (range: 0 to 1 550) in each hospital. Minimal invasive thoracic surgery was performed in 94.3% (601/636) of the hospitals, with 86.6% (551/636) of hospitals carried out video-assisted thoracoscopic (VATS) lobectomy. Among the hospitals performing VATS lobectomy, 89.3% (492/551) of them started to perform the technique after 2006, and 93.1% (513/551) of them do single-direction thoracoscopic lobectomy. A total of 403 640 VATS lobectomies had been performed until 2015, including 163 682 cases of single-direction thoracoscopic lobectomy. In 2015, 73.74% (108 116/146 601) lung cancer operations and 37.44% (25 110/67 076) of esophageal cancer resections were performed by minimally invasive technique. The development level of hospitals among eastern, middle and Western China was different significantly on number of doctors, number of total operations, number of lung cancer surgeries, proportion of minimally invasive lung cancer surgery, number of esophageal cancer surgeries, and proportion of minimally invasive esophageal cancer surgery (χ2∶7.65 to 60.8, all P<0.05).@*Conclusions@#The discipline of thoracic surgery, especially the minimally invasive thoracic surgery in China is now experiencing a rapid development. The proportion of minimally invasive lung cancer surgery is higher than that of in the developed countries. However, unbalanced development among different regions is still a great challenge in China.

ABSTRACT

BACKGROUND@#The incidence of pulmonary embolism (PE) in lung cancer patients who underwent surgery increased during the perioperative period, and prophylactic anticoagulation therapy was important part of enhanced recovery after surgery (ERAS). However, the timing of preventive anticoagulation in patients with lung cancer remained controversial. This study was designed to investigate the safety and efficacy of perioperative prophylactic anticoagulation therapy for lung cancer patients.@*METHODS@#Retrospective research was conducted on 562 lung cancer patients who underwent video-assisted thoracoscopic (VATS) anatomic pulmonary resections in West China Hospital from June 2016 to December 2016. 56 patients were treated with low molecular weight heparin (LMWH) anticoagulation 12 hours before operation until discharge, while the other 506 patients were treated with LMWH 24 hours after operation until discharge. The postoperative chest drainage volume, postoperative bleeding, pulmonary embolism incidence, and respiratory complications were analyzed.@*RESULTS@#(1) There were no significant differences in prothrombin time (PT), activated partial thromboplastin time (APTT) and international normalized ratio (INR) between the pre-operation prophylactic anticoagulation group (PRE group) [(11.5±3.9) s, (27.8±3.5) s, (0.96±0.06) s] and the post-operation prophylactic anticoagulation group (POST group) [(11.4±1.4) s, (28.3±4.0) s, (0.98±0.07) s] (P=0.796, P=0.250, P=0.137), and there was no significant difference in Caprini score between the PRE group (3.1±1.8) and the POST group (3.3±1.5) (P=0.104). (2) There were no significant differences in anesthesia time and intraoperative bleeding between PRE group [(130.2±53.9) min, (76.8±49.3) mL] and POST group [(142.2±56.5) min, (73.7±41.6) mL] (P=0.067, P=0.201). (3) The total drainage volume in 72 hours after operation in PRE group [(728.1±505.7) mL] was significantly higher than that of POST group [(596.4±373.5) mL] (P=0.005), while there were no significant differences between the two groups in total postoperative drainage volume [(1,066.8±1,314.6) mL vs (907.8±999.8) mL, P=0.203]. (4) There were no significant differences between the two groups in pulmonary embolism incidence (1.785% vs 0.019%, P=0.525) and postoperative bleeding rates (1.785% vs 0.039%, P=0.300). (5) There were no significant differences between PRE group and POST group in subcutaneous emphysema incidence (1.785% vs 1.581%, P=0.989) and pulmonary infection rates (14.285% vs 6.324%, P=0.085).@*CONCLUSIONS@#The clinical value of preoperative prophylactic anticoagulation is equal to postoperative prophylactic anticoagulation for lung cancer patients.

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the safety and feasibility of video-assisted thoracic surgery (VATS) anatomic segmentectomy for pulmonary diseases.</p><p><b>METHODS</b>Between November 2009 and July 2011, 20 patients received consecutive VATS anatomic segmentectomy by single surgical group. There were 3 male and 17 female, aging from 32 to 81 years with a mean of 53 years. The patients included 12 cases of non-small cell lung cancer (NSCLC) (5 cases of bronchioloalveolar carcinoma, 6 cases of adenocarcinoma, and 1 case of squamous cell carcinoma), 7 cases of benign diseases (3 cases of bronchiectasis, 2 cases of inflammatory pseudotumor, 1 case of tuberculosis, and 1 case of sclerosing hemangioma) and 1 case of metastasis tumor. The locations of resected segments included 1 anterior segment, 3 posterior segments, 4 apical segments, and 2 superior segments in the right side; and 5 lingular segments, 3 trisegments, and 2 superior segments in the left side. Simultaneously, 3 patients with bronchiectasis underwent segmentectomy and lobectomy, 1 of 6 patients with adenocarcinoma underwent lingulectomy and thymectomy. The pathological TNM stages of 12 NSCLC patients were 9 cases of T1aN0M0, 1 case of T1bN0M0 and 2 cases of T2aN0M0.</p><p><b>RESULTS</b>Of these 20 patients, the median operative time was 155 minutes (range, 120 to 235 minutes), the median blood loss was 50 ml (range, 10 to 600 ml), the median drainage duration was 3 d (range, 1 to 6 d), and the median hospital stay was 6 d (range, 3 to 9 d). One patient who had undergone lingulectomy had a 600 ml intraoperative bleeding from lingular artery, and the bleeding was controlled by suturing the rupture under VATS. Bloody sputum occurred in 2 patients, prolonged air leak occurred in one patient for 5 days, and one patient developed subcutaneous emphysema that spontaneously resolved. No mortality was observed for 30 days after the surgery.</p><p><b>CONCLUSIONS</b>VATS anatomic segmentectomy is a feasible and safe technique with acceptable operative time, less blood loss, fewer complications, and shorter hospital stay.</p>
