ObjectiveTo discuss the clinical characteristics and the management of major complications after thoracic surgery.MethodsRetrospective research was conducted on 15 213 patients who underwent thoracic surgery from January 2008 to September 2018 in our hospital. Thirty-six (0.24%) patients died of postoperative complications. Based on whether major complications such as severe pulmonary pneumonia and other 13 complications were presented postoperatively, the patients were divided into a complication group (n=389, 294 males and 95 females, aged 61.93±10.23 years) and a non-complication group (n=14 785, 8 636 males and 6 149 females, aged 55.27±13.21 years) after exclusion of unqualified patients. The age, gender distribution, diagnosis, surgical approach, postoperative hospital stay, in-hospital costs and other clinical data were analyzed. And the treatment and outcomes of the complications were summarized.ResultsThe age, proportion of male, malignancy and esophageal diseases, postoperative hospital stay and in-hospital costs in the complication group were significantly more or higher than those in the non-complication group (P<0.05). The top three causes of death among the 36 deaths were pulmonary embolism (PE, 25.00%), severe pulmonary pneumonia (16.67%) and acute respiratory failure (16.67%), respectively. The top five complications among the severe complication group were pulmonary pneumonia (24.73%), pleural space (19.83%), anastomotic leak (17.48%), pulmonary atelectasis (11.51%) and PE (6.18%).ConclusionThoracic surgeons should recognize patients with high risk of severe complications preoperatively based on clinical characteristics and perform multi-disciplinary treatment for severe complications.
Objective To analyze the safety of surgical treatment and optimal surgical procedure for lung cancer patients with prior history of lung resection. Methods The medical records of 69 lung cancer patients with history of lung resection was retrospectively collected. There were 53 males and 16 females with a median age of 68 years ranging from 45 to 80 years. The risk factors for postoperative complications were analyzed using one-way ANOVA and logistic regression analysis. By comparing the data between the lobectomy and sublobectomy groups, the best surgical procedure was chosen. Results The 90-day mortality rate was 4.3%. Postoperative complication rate was 24.6%. Results of one-way ANOVA showed that blood loss during operation (P=0.020), tumor size (P=0.007), smoking (P=0.028) and FEV1%pre (P=0.018) were associated with increased major postoperative complications. Logistic regression analysis showed that FEV1%pre<77.0% (OR=0.935, 95%CI 0.888 to 0.984, P=0.010) and tumor size≥2 cm (OR=4.288, 95%CI 1.375 to 13.373, P=0.012) were independent risk factors for major postoperative complications. Lobectomy and sublobectomy groups had similar postoperative mortality and complication rate (P=0.063). Conclusion Surgical resection for selected lung cancer patients with history of lung resection is safe with low postoperative mortality and complication rate. Lobectomy with lymph node resection is the first choice if cardiopulmonary function permits. Pneumonectomy is not recommended.
ObjectiveTo analyze the risks and complications after operation of colorectal cancer in the current version of Database from Colorectal Cancer (DACCA).MethodsThe DACCA version selected for this data analysis was the updated version on July 28th, 2020. The data items included surgery reaction, body temperature, flatus, pain and mental status; preoperative complication, postoperative complication, short-term and long-term complication. The selected data items were statistically analyzed.ResultsThe total number of medical records (data rows) that met the criteria was 6 422, including 4 185 (65.2%) valid data on surgery reaction, 3 833 (59.7%) valid data on body temperature, 3 835 (59.7%) valid data on flatus, 3 597 (56.0%) valid data on pain, 3 551 (55.3%) valid data on mental status, 6 422 (100%) valid data on preoperative complications, postoperative complications, short-term complications and long-term complications. In the surgical response, 1 517 (36.2%) lines of data showed “normal” structure were the most. Among the days with elevated body temperature, the number of 0-day data lines with the structure of “body temperature >37.5 ℃” was the highest, with 1 980 (51.7%). In postoperative flatus, there were 1 675 (43.7%) data lines with the structure showing “3 days”. The largest number of rows (2 755, 76.6%) showed a structure that was “not obvious” in the pain scale. The mental status showed the highest number of “better” rows (2 976, 83.8%). There were 50 preoperative complications (0.8%). And 595 postoperative complications (9.3%), including anastomotic leakage (80, 13.4%), inflammatory ileus (62, 10.4%), pulmonary infection (57, 9.6%), and anastomotic bleeding (56, 9.4%), etc. There were 6 169 (96.1%) without short-term complication in structural form. There were 6 283 (97.8%) without long-term complications.ConclusionsThe changes in complications shown in the real world data from DACCA suggest that the focus of postoperative risks must be changed with the over the follow-up time. As for the complication evaluation system, it is necessary to establish a complete evaluation system combining the corresponding types and risks, to carry out valuable complication researches.
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 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 factors associated with postoperative complications after laparoscopic radical surgery in rectal cancer.MethodsThe clinical data of patients with rectal cancer performed by the laparoscopic radical resection from February 2013 to December 2016 were analyzed retrospectively. All the data were analyzed by the t test, chi-square test or logistic regression analysis.ResultsThere were 343 patients with rectal cancer performed by the laparoscopic radical resection. The postoperative complications occurred in the 97 (28.3%) patients. The result of univariate analysis showed that the postoperative complications rate was associated with the gender, age, body mass index, preoperative anemia, preoperative comorbidity, location and diameter of tumor, operative time, and surgeon experience (all P<0.050). The results of logistic regression analysis revealed that the gender, age, body mass index, preoperative anemia, preoperative comorbidity, location of tumor, operative time, and surgeon experience were the independent risk factors for the postoperative complications (all P<0.050).ConclusionGender, age, body mass index, preoperative anemia, preoperative comorbidity, location of tumor, operative time, and surgeon experience are independent risk factors for postoperative complications in laparoscopic radical rectal surgery for rectal cancer.
Objective To explore the predictive value of neutrophil-to-lymphocyte ratio (NLR) in peripheral blood for postoperative complications of elective endovascular repair for abdominal aortic aneurysm (AAA). Methods From August 2016 to November 2021, the clinical data of patients with AAA who received endovascular isolation repair for the first time in the Department of Vascular Surgery of Beijing Hospital were retrospectively analyzed, including the basic information of the patients, comorbid diseases, and the largest diameter of AAA, preoperative blood labotry test, postoperative complications, long-term survival rate and other indicators. The optimal NLR in peripheral blood was determined, and the differences in postoperative complications and long-term survival rates between the high NLR group and the low NLR group were analysed. Results A total of 120 patients with AAA underwent endovascular isolation for the first time were included in this study, including 105 males and 15 females. The age ranged from 52 to 94 years, with an average of (73.3 ± 8.26) years. The largest diameter of abdominal aortic aneurysm was 35 to 100 mm, with an average of (58.5 ± 12.48) mm. The best cut-off value of NLR for predicting postoperative complications of AAA was 2.45 by using Yoden index screening. Those with NLR ≥2.45 were in the high NLR group (n=66), and those with NLR <2.45 were in the low NLR group (n=54). There was no statistically significant difference between the two groups in the incidence of overall complications and the incidence of sub-complications (P>0.05). The results of logistic regression analysis suggested that NLR was an independent risk factor for complications after endovascular repair of AAA (P<0.05). The median survival time of patients in the high NLR group and the low NLR group was 31.47 months and 35.28 months, respectively, and there was no statistically significant difference between the two groups (P>0.05). Conclusion NLR can be used as a reference predictor of complications after elective endovascular repair of AAA, but more research results are still needed to confirm.
Objective To investigate the risk factors of hypoproteinemia after laparoscopic assisted radical gastrectomy for gastric cancer and its influence on recent clinical outcome. Methods Retrospective case-control study was carried out. Clinical data of 135 patients underwent laparoscopic assisted radical gastrectomy for gastric cancer admitted to the Department of General Surgery in the First Affiliated Hospital of Xi’an Jiaotong University Medical College from June 2016 to June 2021 were collected. Postoperative hypoproteinemia was defined as serum albumin <30 g/Lon postoperative day 1. Observation indications: ① the incidence of hypoproteinemia after laparoscopic assisted radical gastrectomy for gastric cancer; ② analysis of risk factors for postoperative hypoproteinemia; ③ influence of postoperative hypoproteinemia on recent clinical outcome. Results ① Among 135 patients, 56 patients developed hypoproteinemia after operation (hypoproteinemia group) with an incidence of 41.5%, 79 patients without hypoproteinemia (non- hypoproteinemia group). ② Univariate analysis of risk factors for postoperative hypoproteinemia showed that age, preoperative albumin level, preoperative plasma volume, preoperative leukocyte, preoperative hemoglobin level, maximum tumor diameter, net intake on operative day and operative time were related to the occurrence of postoperative hypoproteinemia (P<0.05). The results of multivariate analysis showed that: age ≥65 years [OR=6.320, 95%CI (2.340, 17.068), P＜0.001], preoperative albumin level <35 g/L [OR=5.951, 95%CI (1.815, 19.507), P=0.003], operative time ≥5 h [OR=3.171, 95%CI (1.164, 8.640), P=0.024], and net intake on operative day ≥3 000 mL [OR=5.153, 95%CI (1.616, 16.432), P=0.006] were risk factors for postoperative hypoproteinemia. ③ Within 30 days after operation, the incidence of non surgery related complications in the hypoproteinemia group and the non-hypoproteinemia group were 30.4% (17/56) and 13.9% (11/79), respectively, and the incidence of surgery related complications were 10.7% (6/56) and 1.3% (1/79), respectively, with statistically significant differences (P<0.05). Conclusions Age ≥65 years, preoperative albumin level <35 g/L, operative time ≥5 h and net intake on operative day ≥3 000 mL are risk factors for hypoproteinemia after laparoscopic assisted radical gastrectomy. For patients suffered from hypoproteinemia (albumin <30 g/L) after surgery, the incidences of both surgery-related complications and non-surgery-related complications increase.
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.
Objective To summarize types of post-mastectomy breast reconstruction and present situation. Method The relevant literatures about post-mastectomy breast reconstruction in recent years were reviewed. Results With the increasing incidence of the breast cancer and the progressing of the treatment methods, it has become a trend for the post-mastectomy breast reconstruction. If the patient’s condition is allowed, the post-mastectomy breast reconstruction can be performed. At present, the post-mastectomy breast reconstruction mainly include the implant based reconstruction, autologous tissue reconstruction, autologous fat transplantation, etc.. There are different options for the breast reconstruction according the indicators and it had the corresponding complications. So the selection of reconstruction technique depend on the individual requirements, determining by the patient choice, advice of the reconstructive surgeon, and anticipated post-mastectomy therapy, particularly the needs for the radiotherapy and chemotherapy, etc.. Conclusions Post-mastectomy breast reconstruction is common abroad, corresponding research has been carried out in our country, experiences in learning are shairing. With deepening of domestic and foreign exchanges and progressing of technology, it is believed that post-mastectomy breast reconstruction might become one of conventional reconstruction options in future.
