Objective To classify the postoperative complications (POCs) in patients receiving esophagectomy and find risk factors of different grades of complications. Methods We retrospectively analyzed the clinical data of 298 patients with esophageal cancer who underwent esophagectomy from January 2012 to August 2015 in our hospital. According to the postoperative complications, they were divided into two groups: the complication group (n=113) and the non-complication group (n=185). In the complications group, there were 86 males and 27 females with an average age of 61.42±7.81 years. There were 150 males and 35 females with an average age of 60.39±7.76 years in the non-complication group. The POCs were classified by Clavien-Dindo system. All possible factors influencing the occurrence of grade Ⅱ-Ⅴ POCs were analyzed. Univariate and multivariate analyses were used for seeking independent risk factors of POCs. Results The incidence of grade Ⅱ POCs was 29.87% (89/298), 5.37% (16/298) for grade Ⅲ and 2.68% (8/298) for grade Ⅳ and Ⅴ. The most common POC was lung infection with the incidence of 13.76%. Univariate and multivariate analyses showed the operation duration and the number of lymph node dissection were the independent risk factors of grade Ⅱ-Ⅴ POCs. Conclusion Postoperative lung infection is the major complication in patients receiving esophagectomy. The operation duration and the number of lymph node dissection are the independent risk factors of grade Ⅱ-Ⅴ POCs.
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 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.
Objective To compare anastomotic fistula of modified triple-layer duct-to-mucosa pancreaticojejunostomy and end-to-end invagination pancreaticojejunostomy following pancreaticoduodenectomy. Methods The clinical data of 147 patients underwent pancreaticoduodenectomy from January 2015 to June 2017 in the West China Hospital of Sichuan University were retrospectively analyzed. The modified triple-layer duct-to-mucosa pancreaticojejunostomy were used in 101 cases (MTL group) and end-to-end invagination pancreaticojejunostomy were used in 46 cases (IPJ group). The differences of intraoperative and postoperative statuses were compared between the two groups. Results The baseline data of these two groups had no significant differences (P>0.05). Except for the average time of the pancreaticoenterostomy of the MTL group was significantly longer than that of the IPJ group (P<0.05), the intraoperative blood loss, the first postoperative exhaust time, postoperative hospitalization time, reoperation rate, death rate, and rates of complications such as the pancreatic fistula, biliary fistula, anastomotic bleeding, gastric emptying disorder, and intraperitoneal infection had no significant differences between these two groups (P>0.05). Conclusions Both modified triple-layer duct-to-mucosa pancreaticojejunostomy and end-to-end invagination pancreaticojejunostomy following pancreaticoduodenectomy are safe and effective. An individualized selection should be adopted according to specific situation of patient.
ObjectiveTo evaluate the safety and feasibility of non-nasogastric tube throughout the perioperative period of classical Whipple pancreaticoduodenectomy. MethodsA retrospective analysis was conducted on the clinical data of 63 patients who underwent Whipple pancreaticoduodenectomy at West China Hospital of Sichuan University from June 2020 to August 2023. According to whether nasogastric tube was placed throughout the perioperative period, the patients were divided into nasogastric tube group (NGT group, n=32) and no nasogastric tube group (no NGT group, n=31). The intraoperative indicators such as gastrointestinal anastomosis mode and outcome measures such as postoperative hospital stay were compared between the two groups. Results① Preoperative baseline data: the proportion of benign diseases (P=0.005) and preoperative pancreatitis (P=0.003) of the no NGT group were higher than those of the NGT group, and other preoperative baseline data, such as age and sex, were not statistically significant (P>0.05). ② Intraoperative index: the proportion of circular stapler (P=0.009) was smaller and the operation time was shorter (P<0.001), but there was no significant difference in the anastomosis, intraoperative blood transfusion and intraoperative bleeding (P>0.05). ③ Postoperative outcome measures: the postoperative length of hospital stay (P<0.001) and the incidence of delayed gastric emptying (P<0.001) of the no NGT group were lower than those in the NGT group, but the postoperative time of food intake, incidence of pancreatic fistula, incidence of postoperative bleeding, and Clavien-Dindo grade of complications were not significant (P>0.05), and on one died within 30 d after operation. ConclusionsThe results of this study preliminarily show that, it is safe and feasible not to place nasogastric tubes throughout the perioperativeperiod in patients undergoing classical Whipple pancreaticoduodenectomy. Compared with placing nasogastric tube, it can shorten the postoperative hospital stay, reduce the incidence of postoperative delayed gastric emptying.
ObjectiveTo compare the outcomes of laparoscopic appendectomy (LA) and open appendectomy (OA) for the acute appendicitis patients based on our extensive experiences. MethodsThe data of all the acute appendicitis patients who underwent appendectomy from January 2013 to December 2014 in our department were retrospectively reviewed. A total of 201 patients were enrolled and divided into LA group (n=102) and OA group (n=99). The relevant clinical indexes during and after operation of two groups were compared. ResultsThere were no significant difference in age, gender, and underlying disease between LA and OA patients (P > 0.05). And the abdominal cavity infection rate, abdominal drainage rate and 30-day readmission rate were also similar (P > 0.05). But LA group had less operative time, lower infection operative wound rate, less intestinal function recovery time, shorter inhospital days and higher hospital expenses than OA group (P < 0. 05). In addition, perforated appendix and LA could increase the rate of abdominal drainage[OR=2.710, 95% CI(1.129, 6.507), P=0.026]. ConclusionsBoth LA and OA are safe and effective methods for the treatment of acute appendicitis. But LA has several advantages over OA on less operative time and postoperative complications, earlier recovery, and shorter inhospital days. While LA have higher hospital cost than OA, it still should be considered as a prefer way to cure acute appendicitis. LA is a independent risk factor of abdominal drainage.
ObjectiveTo investigate the clinical value of the C-reactive protein (CRP) ratio (CRP value on postoperative day 3/day 1) as an early predictor of postoperative severe complication after laparoscopic gastrectomy (LG) for gastric cancer.MethodsThis retrospective study examined the relationship between the occurrence of severe complication and the CRP ratio of 259 gastric cancer patients, who underwent LG in the Department of General Surgery of General Hospital of Fuxin Mining Industry Group of Liaoning Health Industry Group from January 2015 to January 2020. According to Clavien-Dindo (CD) grading system, gastric cancer patients were divided into the severe postoperative complication group (n=41, 15.8%) and the non-severe postoperative complication group (n=218, 84.2%). The relationship between CRP ratio and clinicopathologic characteristics of patients and the predictive value of CRP ratio for severe complication were analyzed.ResultsThe optimal cutoff value of CRP ratio of 2.2 offered 63.2% sensitivity, 91.0% specificity, 70.7% positive predictive value, and 85.8% negative predictive value for severe postoperative complication. The area under the receiver operating characteristic curve was 0.766. There had distinct differences (P<0.05) on body mass index, preoperative comorbidity, type of surgery, T stage, and TNM stage between the high CRP ratio group (CRP ratio >2.2, n=60) and the low CRP ratio group (CRP ratio ≤2.2, n=199). Logistic regression showed that preoperative comorbidity [OR=3.624, 95%CI (1.191, 11.206), P=0.023], later of TNM stage [OR=9.037, 95% CI (1.729, 47.226), P=0.009], and CRP ratio >2.2 [OR=20.473, 95%CI (7.948, 52.737), P<0.001] were independent risk factors for postoperative severe complication after LG.ConclusionThere must to be paid enough attention to the CRP ratio >2.2 on the day 1 and 3 after LG, it suggests that there might be a risk of severe postoperative complications.
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 investigate the efficacy of early, short-term, low-dose corticosteroid administration for the prevention and treatment of early acute lung injury (EALI) in patients undergoing thoracoscopic lobectomy. MethodsA retrospective analysis was conducted on the clinical data of patients who underwent thoracoscopic lobectomy at the Department of Thoracic and Cardiovascular Surgery, Taihe Hospital, Hubei University of Medicine, from January 2019 to January 2022. Patients were divided into an early steroid therapy group and an observation group based on whether they received corticosteroids in the early postoperative period. In the early steroid therapy group, in addition to standard postoperative care, patients received a low-dose intravenous push of methylprednisolone (80-120 mg/d) for 3 consecutive days. In the observation group, patients received standard postoperative care without intravenous corticosteroids for the first 3 days. Chest plain CT scans were performed on postoperative day (POD) 1 and POD 3 or 4 to evaluate lung injury. CT scores and the incidence of postoperative EALI were recorded. ResultsA total of 521 patients were included (268 males, 253 females; age range: 11-80 years). There were 318 patients in the observation group and 203 in the early steroid therapy group. On POD 1, the incidence of EALI was 16.0% in the observation group and 13.8% in the early steroid therapy group, with no statistical difference (P=0.486). Correspondingly, there was no statistical difference in chest CT scores among EALI-positive patients between the two groups (P=0.927). On POD 3-4, the incidence of EALI was significantly lower in the early steroid therapy group (22.7%) compared to the observation group (33.6%) (P=0.007). Although chest CT scores among EALI-positive patients were lower in the early steroid therapy group, the difference was not statistically significant (P=0.377). The overall incidence of EALI within the first 4 postoperative days was significantly lower in the early steroid therapy group (26.1%) than in the observation group (37.4%) (P=0.007). Radiological progression (defined as new-onset EALI or progression of existing EALI) occurred in 14.8% of the early steroid therapy group, significantly lower than the 28.9% in the observation group (P<0.001). The early steroid therapy group had a shorter postoperative length of stay (P<0.001), while there was no statistical difference in the incidence of poor wound healing between the groups (P=0.762). Conclusion Early postoperative corticosteroid use effectively reduces the incidence of EALI on POD 3-4, lowers the risk of radiological progression, and decreases the overall incidence of postoperative EALI. This is achieved without prolonging the length of stay or increasing the risk of poor wound healing. Therefore, early administration of low-dose corticosteroids is beneficial in suppressing the occurrence and progression of EALI. Its early use is recommended for patients at high risk for postoperative EALI.
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.
