ObjectiveTo understand the impact of preoperative nutritional status on the postoperative complications for patients with low/ultra-low rectal cancer undergoing extreme sphincter-preserving surgery following neoadjuvant therapy. MethodsThe patients with low/ultra-low rectal cancer who underwent extreme sphincter-preserving surgery following neoadjuvant therapy from January 2009 to December 2020 were retrospectively collected using the Database from Colorectal Cancer (DACCA), and then who were assigned into a nutritional risk group (the score was low than 3 by the Nutrition Risk Screening 2002) and non-nutritional risk group (the score was 3 or more by the Nutrition Risk Screening 2002). The postoperative complications and survival were analyzed for the patients with or without nutritional risk. The postoperative complications were defined as early-term (complications occurring within 30 d after surgery), middle-term (complications occurring during 30–180 d after surgery), and long-term (complications occurring at 180 d and more after surgery). The survival indicators included overall survival and disease-specific survival. ResultsA total of 680 patients who met the inclusion criteria for this study were retrieved from the DACCA database. Among them, there were 500 (73.5%) patients without nutritional risk and 180 (26.5%) patients with nutritional risk. The postoperative follow-up time was 0–152 months (with average 48.9 months). Five hundreds and forty-three survived, including 471 (86.7%) patients with free-tumors survival and 72 (13.3%) patients with tumors survival. There were 137 deaths, including 122 (89.1%) patients with cancer related deaths and 15 (10.9%) patients with non-cancer related deaths. There were 48 (7.1%) cases of early-term postoperative complications, 51 (7.5%) cases of middle-term complications, and 17 (2.5%) cases of long-term complications. There were no statistical differences in the incidence of overall complications between the patients with and without nutritional risk (χ2=3.749, P=0.053; χ2=2.205, P=0.138; χ2=310, P=0.578). The specific complications at different stages after surgery (excluding the anastomotic leakage complications in the patients with nutritional risk was higher in patients without nutritional risk, P=0.034) had no statistical differences between the two groups (P>0.05). The survival curves (overall survival and disease-specific survival) using the Kaplan-Meier method had no statistical differences between the patients with and without nutritional risk (χ2=3.316, P=0.069; χ2=3.712, P=0.054). ConclusionsFrom the analysis results of this study, for the rectal cancer patients who underwent extreme sphincter-preserving surgery following neoadjuvant therapy, the patients with preoperative nutritional risk are more prone to anastomotic leakage within 30 d after surgery. Although other postoperative complications and long-term survival outcomes have no statistical differences between patients with and without nutritional risk, preoperative nutritional management for them cannot be ignored.
ObjectiveTo explore the application value of prognostic nutritional index (PNI) in the postoperative complications of McKeown surgery for da Vinci robotic esophageal cancer. MethodsThe clinical data of the patients who underwent da Vinci robotic McKeown surgery for esophageal cancer in the Department of Thoracic Surgery of the First Hospital of Lanzhou University from January 2019 to June 2022 were retrospectively collected. According to the receiver operating characteristic (ROC) curve, the optimal cut-off value of PNI for predicting postoperative complications was explored. The patients were divided into a high PNI group and a low PNI group according to the cut-off value, and the differences in basic characteristics, surgery-related indexes and postoperative complications between the two groups were analyzed. According to the occurrence of postoperative complications, the patients were divided into a non-complication group and a complication group. Univariate and multivariate analyses were used to explore the influence of relevant indicators on the occurrence of postoperative complications in da Vinci robotic McKeown surgery for esophageal cancer. ResultsFinally 120 patients were collected, including 95 males and 25 females, with an average age of 62.82 years. The preoperative hemoglobin content, preoperative blood lymphocyte count, preoperative serum albumin and preoperative blood total cholesterol in the high PNI group were higher than those in the low PNI group (P<0.05). There were statistical differences between the two groups in the incidences of postoperative overall complications, pulmonary infection, pleural effusion and poor incision healing (P<0.05). The relevant indicators that may cause postoperative complications were included in univariate analysis, and the results showed that age, operation time, intraoperative blood loss, preoperative blood lymphocyte count, preoperative hemoglobin content, preoperative blood mononuclear cell count, preoperative blood monocyte count, serum albumin level and PNI were possible influencing factors of postoperative complications after da Vinci robotic McKeown surgery for esophageal cancer. Incorporating these influencing factors into multivariate analysis, the results showed that age, PNI, operation time and intraoperative blood loss were independent influencing factors of postoperative complications. ConclusionPNI has certain predictive value in the postoperative complications of da Vinci robotic McKeown surgery for esophageal cancer. PNI is an independent factor affecting postoperative complications. Improving the level of PNI in esophageal cancer patient before surgery may help reduce the occurrence of postoperative complications.
ObjectiveTo explore the treatment strategies for patients with fever and pulmonary complications after thoracic surgery during COVID-19 epidemic.MethodsThe clinical data of 537 patients who ungerwent selective surgery at the Department of Thoracic Surgery, Shangjin Branch of West China Hospital between February and December 2020 were retrospectively analyzed, including 242 (45.1%) males and 295 (54.9%) females aged 53.3±13.4 years. We have established a procedure for the patients with fever and pulmonary complications after thoracic surgery to investigate the cause of the disease and track risk factors.ResultsThe overall postoperative complication rate was 16.4% (88/537), and 1 (0.2%) patient died. Of 537 patients, 179 (33.3%) patients were enrolled in our model according to the inclusion criteria: ratio of males [112 (62.6%) vs. 130 (36.3%), P<0.010], patients with a history of smoking [74 (41.3%) vs. 87 (24.3%), P<0.010], or with esophageal cancer surgery [36 (20.1%) vs. 15 (4.2%)], or with traditional thoracotomy [14 (7.8%) vs. 4 (1.1%)] was higher than that of the other patients. Patients in our process due to fever or pulmonary complications had longer ICU stay and postoperative hospital stay (P=0.010). Logistic regression multivariate analysis showed that gender was an independent risk factor for postoperative fever or pulmonary complications.ConclusionIn low-risk areas of the epidemic, the treatment process is simple and feasible, and the cause traceability and corresponding treatment can basically be completed within 24 hours. At the same time, the treatment process has been running stably for a long time.
ObjectiveTo investigate the predictive value of prognostic nutritional index (PNI) in complications after thoracoscopy-assisted radical resection of esophageal cancer.MethodsWe collected the clinical data of patients who underwent thoracoscopy-assisted esophagectomy in the First Affiliated Hospital of Xinjiang Medical University from January 2015 to June 2020. The predictive value of PNI for postoperative complications was evaluated by establishing receiver operating characteristic (ROC) curve and the optimal cut-off point was determined. The patients were divided into a high PNI group and a low PNI group according to the cut-off point. The differences of baseline data and perioperative complications-related indicators between the two groups were compared and analyzed. Univariate and multivariate analyses were used to investigate the influence of PNI and other related indexes on postoperative complications.ResultsA total of 116 patients were enrolled in this study, including 75 males and 41 females, aged 65 (58-69) years. The area under ROC curve was 0.647, and the optimal cut-off point was 51.9. According to the cut-off point, there were 45 patients in the high PNI group and 71 patients in the low PNI group. The overall complication rate (χ2=10.437, P=0.001) and the incidence of postoperative pulmonary infection (χ2=10.811, P=0.001) were statistically different between the two groups. The results of univariate analysis showed that the duration of ventilator use (Z=–3.136, P=0.002), serum albumin value (t=2.961, P=0.004), and PNI value (χ2=10.437, P=0.001) were the possible risk factors for postoperative complications after thoracoscopy-assisted esophagectomy. The results of multivariate analysis suggested that the duration of ventilator use (OR=1.015, P=0.002) and the history of drinking (OR=5.231, P=0.013) were independent risk factors for postoperative complications, and high PNI was the protective factor for postoperative complications (OR=0.243, P=0.047).ConclusionPNI index has a certain value in predicting postoperative complications, which can quantify the preoperative nutritional and immune status of patients. Drinking history and duration of ventilator use are independent risk factors for postoperative complications of thoracoscopy-assisted esophagectomy, and high PNI is a protective factor for postoperative complications.
Objective To explore the predictive value of cardiopulmonary exercise test (CPET) combined with clinical indexes in the postoperative complications. Methods The clinical data and CPET data (including lung function) of patients undergoing radical esophagectomy in Xuzhou Central Hospital from January 2018 to March 2022 were collected. Univariate analysis and multivariate logistic regression analysis were used to analyze the meaningful evaluation index for the occurrence of postoperative complications. Results A total of 77 patients with esophageal cancer were included, including 59 (76.6%) males and 18 (23.4%) females aged 47-80 years. There were 42 (54.5%) patients in the non-complication group and 35 (45.5%) patients in the complication group. Univariate analysis results showed that the occurrence of postoperative complications was significantly correlated with age, body mass index (BMI), smoking index, tumor stage, the length of postoperative hospital stay, peak work rate (WRpeak), peak kilogram oxygen uptake (VO2peak/kg), the ventilatory equivalent for carbon dioxide slope (VE/VCO2 slope), forced expiratory volume in the first second/forced vital capacity (FEV1/FVC) and maximum expiratory flow rate (MMEF) (P<0.05). The results of multivariate logistic regression analysis showed that BMI [OR=1.35, 95%CI (1.03, 1.77), P=0.031], peakVO2/kg [OR=0.64, 95%CI (0.45, 0.93), P=0.018], oxygen uptake-anaerobic threshold (ATVO2) [OR=0.66, 95%CI (0.44, 0.98), P=0.044] and VE/VCO2 slope [OR=1.49, 95%CI (1.10, 2.02), P=0.011] were the related indexes of complications after radical resection of esophageal cancer. The sensitivity of BMI, VO2peak/kg, ATVO2/kg and VE/VCO2 slope in predicting postoperative complications was 82.10%, and the specificity was 87.44%, 95%CI (0.744, 0.955). Conclusion BMI, VO2peak/kg, ATVO2/kg and VE/VCO2 slope can be used as predictors for postoperative complications of esophageal cancer.
ObjectiveTo investigate the predictive value of preoperative red blood cell distribution width to platelet count ratio (RPR) and platelet-albumin-bilirubin (PALBI) scoring for postoperative complications after radical resection of hepatic alveolar echinococcosis (HAE). MethodsAccording to the inclusion and exclusion criteria, the clinicopathologic data of patients diagnosed with HAE and underwent radical hepatectomy in the Affiliated Hospital of Qinghai University from January 2018 to October 2022 were retrospectively collected. The risk factors affecting postoperative complications after radical hepatectomy for HAE were analyzed by univariate and multivariate unconditional logistic regression analysis, which were used to construct the nomogram. The receiver operating characteristic curve was used to evaluate the value in predicting postoperative complications by nomogram model. The discrimination of the nomogram was evaluated using Bootstrap internal 1 000 resampling and evaluated using a consistency index. The predicted postoperative complications probability by nomogram and actual postoperative complications probability were calculated by Kaplan-Meier method, and the calibration curve was drawn. The calibration ability of the nomogram model was evaluated by Hosmer-Lemeshow goodness-of-fit test. The decision curve analysis was used to evaluate clinical benefit of the nomogram model. ResultsA total of 160 patients with HAE radical hepatectomy were included, of which 105 had no postoperative complications and 55 had postoperative complications. The multivariate unconditional logistic regression analysis showed that the operation time ≥207 min, intraoperative bleeding ≥650 mL, and albumin ＜38 g/L, RPR ≥0.054, and higher PALBI grading (3 levels) were the risk factors affecting postoperative complications after HAE radical hepatectomy (OR＞1, P<0.05). Based on the risk factors, the nomogram was constructed. The area under the receiver operating characteristic curve (95%CI) predicted by the nomogram for the postoperative complications was 0.873 (0.808, 0.937), with an optimal cutoff value of 0.499. The consistency index was 0.855 for discriminating postoperative complications after HAE radical hepatectomy. The calibration curve was tested by Hosmer-Limeshow and showed a good fit between the predicted curve by the nomogram and actual curve (χ2=3.193, P=0.367), indicating that the nomogram had a good calibration ability. The decision curve analysis showed that there was a good clinical applicability within the range of 11% to 93% of the threshold probability. ConclusionsThe preoperative RPR and PALBI scoring are risk factors affecting postoperative complications after radical hepatectomy for HAE. The nomogram constructed with risk factors including RPR and PALBI has a good predictive value for postoperative complications after radical hepatectomy for HAE.
ObjectiveTo investigate the risk factors affecting severe postoperative complications (Clavien-Dindo classification Ⅲa or higher) in patients with end-stage hepatic alveolar echinococcosis (HAE) underwent ex vivo liver resection and autotransplantation (ELRA), and to develop a nomogram prediction model. MethodsThe clinical data of end-stage HAE patients who underwent ELRA at the West China Hospital of Sichuan University from January 2014 to June 2024 were retrospectively analyzed. The logistic regression was used to analyze the risk factors affecting severe postoperative complications. A nomogram prediction model was established basing on LASSO regression and its efficiency was evaluated using receiver operating characteristic (ROC) curve, calibration curve, and decision curve analysis. Simultaneously, a generalized linear model regression was used to explore the preoperative risk factors affecting the total surgery time. Test level was α=0.05. ResultsA total of 132 end-stage HAE patients who underwent ELRA were included. The severe postoperative complications occurred in 47 (35.6%) patients. The multivariate logistic analysis results showed that the patients with invasion of the main trunk of the portal vein or the first branch of the contralateral portal vein (type P2) had a higher risk of severe postoperative complications compared to those with invasion of the first branch of the ipsilateral portal vein (type P1) [odds ratio (OR) and 95% confidence interval (CI)=8.24 (1.53, 44.34), P=0.014], the patients with albumin bilirubin index (ALBI) grade 1 had a lower risk of severe postoperative complications compared to those with grade 2 or higher [OR(95%CI)=0.26(0.08, 0.83), P=0.023]. Additionally, an increased total surgery time or the autologous blood reinfusion was associated with an increased risk of severe postoperative complications [OR(95%CI)=1.01(1.00, 1.01), P=0.009; OR(95%CI)=1.00(1.00, 1.00), P=0.043]. The nomogram prediction model constructed with two risk factors, ALBI grade and total surgery time, selected by LASSO regression, showed a good discrimination for the occurrence of severe complications after ELRA [area under the ROC curve (95%CI) of 0.717 (0.625, 0.808)]. The generalized linear regression model analysis identified the invasion of the portal vein to extent type P2 and more distant contralateral second portal vein branch invasion (type P3), as well as the presence of distant metastasis, as risk factors affecting total surgery time [β (95%CI) for type P2/type P1=110.26 (52.94, 167.58), P<0.001; β (95%CI) for type P3/type P1=109.25 (50.99, 167.52), P<0.001; β (95%CI) for distant metastasis present/absent=61.22 (4.86, 117.58), P=0.035]. ConclusionsFrom the analysis results of this study, for the end-stage HAE patients with portal vein invasion degree type P2, ALBI grade 2 or above, longer total surgery time, and more autologous blood transfusion need to be closely monitored. Preoperative strict evaluation of the first hepatic portal invasion and distant metastasis is necessary to reduce the risk of severe complications after ELRA. The nomogram prediction model constructed based on ABLI grade and total surgery time in this study demonstrates a good predictive performance for severe postoperative complications, which can provide a reference for clinical intervention decision-making.
ObjectiveTo compare the effects of transthoracic device closure and traditional surgical repair on atrial septal defect systemically.MethodsA systematic literature search was conducted using the PubMed, EMbase, The Cochrane Library, VIP, CNKI, CBM, Wanfang Database up to July 31, 2018 to identify trials according to the inclusion and exclusion criteria. Quality was assessed and data of included articles were extracted. The meta-analysis was conducted by RevMan 5.3 and Stata 12.0 software.ResultsThirty studies were identified, including 3 randomized controlled trials (RCTs) and 27 cohort studies involving 3 321 patients. For success rate, the transthoracic closure group was lower than that in the surgical repair group (CCT, OR=0.34, 95%CI 0.16 to 0.69, P=0.003). There was no statistical difference in mortality between the two groups (CCT, OR=0.43, 95%CI 0.12 to 1.52, P=0.19). Postoperative complication occurred less frequently in the transthoracic closure group than that in the surgical repair group (RCT, OR=0.30, 95%CI 0.12 to 0.77, P=0.01; CCT, OR=0.27, 95%CI 0.17 to 0.42, P<0.000 01). The risk of postoperative arrhythmia in the transthoracic closure group was lower than that in the surgical repair group (CCT, OR=0.56, 95%CI 0.34 to 0.90, P=0.02). There was no statistical difference in the incidence of postoperative residual shunt in postoperative one month (CCT, OR=4.52, 95%CI 0.45 to 45.82, P=0.20) and in postoperative one year (CCT, OR=1.03, 95%CI 0.29 to 3.68, P=0.97) between the two groups. Although the duration of operation (RCT MD=–55.90, 95%CI –58.69 to –53.11, P<0.000 01; CCT MD=–71.68, 95%CI –79.70 to –63.66, P<0.000 01), hospital stay (CCT, MD=–3.31, 95%CI –4.16, –2.46, P<0.000 01) and ICU stay(CCT, MD=–10.15, 95%CI –14.38 to –5.91, P<0.000 01), mechanical ventilation (CCT, MD=–228.68, 95%CI –247.60 to –209.77, P<0.000 01) in the transthoracic closure group were lower than those in the traditional surgical repair group, the transthoracic closure costed more than traditional surgical repair during being in the hospital (CCT, MD=1 221.42, 95%CI 1 124.70 to 1 318.14, P<0.000 01).ConclusionCompared with traditional surgical repair, the transthoracic closure reduces the hospital stay, shortens the length of ICU stay and the duration of ventilator assisted ventilation, while has less postoperative complications. It is safe and reliable for patients with ASD within the scope of indication.
ObjectiveTo provide clinical reference for the perioperative management of esophageal cancer patients with different stages of chronic obstructive pulmonary disease (COPD) through investigating the impact of COPD on postoperative complications and survival in esophageal cancer patients undergoing oesophagectomy.MethodsThe clinical data of 163 patients who underwent radical resection of esophageal cancer in our department from January 2015 to January 2018 were retrospectively analyzed, including 124 males and 39 females, with a median age of 64 years (IQR: 23.8 years). They were divided into a COPD group (n=87) and a non-COPD group (n=76) according to the presence of COPD before operation. The clinical data were collected and the postoperative complications and 2-year survival between the two groups were compared and analyzed.ResultsThe incidence of major postoperative complications (pulmonary infection, respiratory failure, arrhythmia and anastomotic leakage) in the COPD group were higher than those in the non-COPD group (all P<0.05). Spearman correlation analysis showed that the severity of preoperative COPD was positively correlated with the incidence of postoperative complications in patients with esophageal cancer (r=0.437, P<0.001). The incidence of postoperative respiratory failure and mortality in patients with severe COPD were significantly higher than those in patients without COPD and those with mild or moderate COPD. The 2-year survival rate of patients with esophageal cancer in the COPD group was lower than that in the non-COPD group (56.1% vs. 78.5.%, P=0.001), and the severity of COPD was negatively correlated to the survival rate.ConclusionCOPD significantly increases the incidence of postoperative complications in patients with esophageal cancer, which is not conducive to the prognosis of patients, and the severity of COPD is correlated with postoperative complications and 2-year survival rate.
Objective To analyze the influence of the ABO blood types of colorectal cancer patients served by West China Hospital as a regional center on surgical characteristics and postoperative complications in the current version of Database from Colorectal Cancer (DACCA). Methods The DACCA version was updated on January 5, 2022. The data items included ABO blood type, sex, type of operation, nature of operation and postoperative complications. The operative characteristics and complications at different stages after operation (in hospital, short-term and long-term after operation) of colorectal cancer patients with different blood types (A, B, AB, O) were analyzed. Results According to the DACCA database, we obtained 5 010 analysable data rows, covering 2005–2022. The results of blood types analysis showed that there was no significant difference among different blood types in the overall postoperative complications and the occurrence of complications in hospital, short-term and long-term after operation (P>0.05). Further subgroup analysis showed that only the difference of anastomotic leakage among different blood types was statistically significant (χ2=9.588, P=0.022). There was no significant difference among different blood types in whether the primary focus of colon cancer surgery was removed or not, the degree of radical resection of the primary focus, and whether the anus was preserved or not in rectal cancer surgery (P>0.05), and there was significant difference among different blood types with different degrees of radical resection of primary rectal cancer (χ2=15.773, P=0.001). Conclusions The ABO blood types of patients with colorectal cancer has nothing to do with the occurrence of overall complications in the short and long term after operation, and has no impact on the implementation of different surgical methods. However, the occurrence of a single postoperative anastomotic leakage is related to blood type, and its possible causes need to be further explored.
