ObjectiveTo explore effect of preoperative prognostic nutritional index (PNI) on clinically related postoperative pancreatic fistula (CR-POPF) after distal pancreatectomy (DP) and analyze its influencing factors in order to provide a basis for clinical prediction of CR-POPF. MethodsThe clinicopathologic data of patients who successfully completed DP in the Affiliated Hospital of Xuzhou Medical University and met the inclusion and exclusion criteria of this study from January 1, 2017 to January 31, 2021 were collected retrospectively. The preoperative PNI value was calculated and the optimal cut-off value was obtained according to the receiver operative characteristic (ROC) curve. The patients were divided into low and high PNI based on the optimal cut-off value. The clinicopathologic characteristics were compared between the patients with low and high PNI and CR-POPF or not. At the same time, multivariate logistic regression was used to analyze the influencing factors of CR-POPF. ResultsA total of 143 patients who met the inclusion and exclusion criteria were included in this study. The CR-POPF occurred in 33 cases (23.08%) after DP, and the average preoperative PNI was 52.26 (39.20–65.10), the optimal cut-off value of PNI was 50.55, with 49 cases in the low PNI group and 94 cases in the high PNI group. In patient with low PNI, the proportions of patients aged ≥65 years and with CR-POPF were higher than those with high PNI (P<0.05). In the patients with CR-POPF, the proportions of patients with soft pancreatic texture and with low preoperative PIN were higher than those without CR-POPF (P<0.05). Further, the multivariate logistic regression showed that the the preoperative low PNI (OR=5.417, P<0.001) and soft pancreatic texture (OR=4.126, P=0.002) increased the risk of CR-POPF. ConclusionLow preoperative PNI and soft pancreatic texture increase risk of CR-POPF after DP, and it is necessary to preoperatively evaluate PNI status of patients.
ObjectiveTo explore the related factors of postoperative survival of patient with gastric cancer, so as to provide the corresponding evidence support for the prognosis evaluation.MethodsThe clinicopathologic data of patients with gastric cancer who underwent surgical treatment in the Fourth Affiliated Hospital of Baotou Medical College and the Fourth Hospital of Baotou City from January 2006 to December 2009 were retrospectively collected. The influences of clinicopathologic data (gender, age, tumor size, tumor location, lymph node metastasis, tumor thrombus, tumor differentiation, TNM stage, operation mode, and postoperative chemotherapy) on postoperative survival of patients with gastric cancer were analyzed. Univariate analysis was used to analyze the influencing factors of postoperative survival in the patients with gastric cancer and Cox proportional hazards regression was used to analyze the independent risk factors.ResultsA total of 80 patients with gastric cancer were included in this study. Up to December 31, 2014, the median survival time at 50% cumulative survival rate was 95 months. Univariate analysis showed that the survival of patients with gastric cancer was related to tumor size, lymph node metastasis, tumor differentiation, and TNM stage (P<0.05). Further multivariate analysis showed that later TNM stage was an independent risk factor for affecting postoperative survival of patients with gastric cancer (P<0.05).ConclusionPostoperative survival of patients with gastric cancer is related to tumor size, lymph node metastasis, tumor differentiation, and TNM stage; And later TNM stage is an independent risk factor for affecting survival of patients with gastric cancer.
ObjectiveTo compare the complications and clinical scores of posterior lumbar intervertebral fusion (PLIF) in middle-aged and older patients of different ages, and to assess the risk of complications of PLIF in different ages, providing a reference for clinical treatment.MethodsThe clinical data of 1 136 patients, who were more than 55 years old and underwent PLIF between June 2013 and June 2016, were retrospectively analyzed. According to the age of patients undergoing surgery, they were divided into 3 groups as 55-64 years old, 65-74 years old, and ≥75 years old. The general characteristics, comorbidities, and surgical data of the three groups were compared, with comparison the morbidity of complications. According to the minimal clinical important difference (MCID), the improvement of patient’s pain visual analogue scale (VAS) score and the Oswestry disability index (ODI) score were compared. Univariate logistic regression analysis was used to analyze the difference of complications and the improvement of VAS and ODI scores. Multivariate logistic regression analysis was performed for the risk factors of complications.ResultsThere were significant differences in the number of surgical fusion segments and osteoporosis between groups (P<0.05); there was no significant difference in gender, body mass index, operation time, preoperative American Society of Anesthesiologists (ASA) classification, and comorbidities between groups (P>0.05). All patients were followed up 6-62 months with an average of 27.4 months. Among the results of postoperative complications, there were significant differences in the total incidence of intraoperative complications, systemic complications, minor complications, and the percentage of improvement of ODI score to MCID between groups (P<0.05); but there was no significant difference in the total incidence of complications at the end of long-term follow-up and the percentage of improvement of VAS score to MCID between groups (P>0.05). Univariate logistic regression analysis showed that after adjusting the confounding factors, there were significant differences in intraoperative complications and the percentage of improvement of ODI score to MCID between 55-64 and 65-74 years old groups (P<0.05); systemic complications, minor complications, complications at the end of long-term follow-up, and the percentage of improvement of ODI score to MCID in ≥75 years old group were significantly different from those in the other two groups (P<0.05). Multivariate logistic regression analysis showed that age was a risk factor for systemic complications, minor complications, and complications at the end of long-term follow-up. Except for age, long operation time was a risk factor for intraoperative complications, increased number of fusion segments was a risk factor for systemic complications, the number of comorbidities was a risk factor for minor complications, and osteoporosis was a risk factor for complications at the end of long-term follow-up.ConclusionThe risk of surgical complications is higher in the elderly patients (≥75 years) with lumbar degenerative diseases than in the middle-aged and older patients (<75 years), while the improvements of postoperative VAS and ODI scores were similar. Under the premise of fully assessing surgical indications, PLIF has a positive effect on improving the elderly patients’ quality of life.
Objective To analyze the influencing factors of single-center day surgery patients who are discharged from the hospital on the same-day, in order to provide reference and basis for the clinical practice of follow-up day surgery. Methods The electronic medical records of patients who underwent day surgery in the Day Surgery Center of the First Affiliated Hospital of the Air Force Military Medical University between February and October 2021 were analyzed retrospectively. The patients were divided into the same-day discharge group and non-same-day discharge group. The baseline data and perioperative indicators of the patients were analyzed. Results A total of 857 patients were included, including 264 patients (30.81%) in the same-day discharge group and 593 patients (69.19%) in the non-same-day discharge group. Univariate analysis showed that there were significant differences between the two groups in gender, age, body mass index, whether the first one, disease classification, anesthesia method, and intraoperative blood loss (P<0.05). Logistic regression analysis showed that gender, whether the first one, disease classification, surgical grade, anesthesia method, and intraoperative blood loss were independent factors affecting the delayed discharge of patients undergoing daytime surgery (P<0.05). Conclusions There are many factors that affect day surgery patients’ discharge. It is suggested that more rigorously screen patients for day surgery, improve medical technology, strengthen out-of-hospital continued care, and optimize management procedures, so as to shorten the time of patients in hospital and provide more information for patients, and provide more efficient and convenient medical services for patients.
Objective To analyze the factors influencing day surgery developing towards same-day surgery, and provide a reference for the promotion of same-day surgery. Methods A questionnaire on influencing factors of same-day surgery was prepared based on structural equation modeling (SEM), including 6 dimensions and 23 items. From January to October 2021, at the Day Surgery Center of West China Hospital, Sichuan University, the random sampling method was used to select the research subjects for a questionnaire survey, and SEM was used to analyze the factors impacting the iterative development of day surgery to same-day surgery service model. Results A total of 200 questionnaires were distributed, and 192 valid questionnaires were recovered, with an effective recovery rate of 96.0%. The Cronbach’s α coefficient of the questionnaire was 0.857, and the Cronbach’s α coefficient of each dimension was from 0.832 to 0.934. The KMO test value was 0.822, and the result of Bartlett sphericity test was χ2=4568.330, P<0.001. The model fit indexes met the standard requirements well. The result of SEM revealed that the standard path coefficients of “the hospital’s preliminary preparation for day surgery developing towards same-day surgery” impacting “the guarantee system related to surgical quality and safety”, “the guarantee system related to surgical quality and safety” impacting “the public’s awareness of day surgery developing towards same-day surgery”, “the guarantee system related to surgical quality and safety” impacting “the ‘hospital-community’ integrated collaboration network”, “the public’s awareness of day surgery developing towards same-day surgery” impacting “the ‘hospital-community’ integrated collaboration network”, and “the ‘hospital-community’ integrated collaboration network” impacting “the iterative upgrade of day surgery” were all larger than 0.5, indicating strong influences between these factors, but the absolute value of standard path coefficient of the “hospital’s development brought by the transform of day surgery to same-day surgery” impacting “the guarantee system related to surgical quality and safety” was smaller than 0.3. Conclusion The hospital’s preliminary preparation, the guarantee system related to surgical quality and safety, the development of the “hospital-community” integrated collaboration network, and the public’s awareness are the probable factors influencing the iterative development of day surgery to same-day surgery.
ObjectiveTo investigate the incidence of perioperative anemia and the influencing factors of preoperative anemia in patients with colorectal cancer.MethodsThe clinicopathological data of 1 250 patients with colorectal cancer who underwent surgery in our hospital from January 1, 2019 to December 31, 2019 were analyzed retrospectively. According to the preoperative hemoglobin level, patients were divided into anemia group and non-anemia group. Univariate analysis and multivariate logistic regression analysis were used to explore the influencing factors of preoperative anemia in patients with colorectal cancer, and the effects of preoperative anemia on intraoperative blood transfusion, postoperative complications, and postoperative hospital stay were analyzed.ResultsThe incidence of preoperative anemia in patients with colorectal cancer was 40.6% (508/1 250), and the incidence of preoperative anemia in patients with right colon cancer, left colon cancer, and rectal cancer was 66.0% (192/291), 41.1% (139/338), and 28.5% (177/621), respectively. The incidence of postoperative anemia in patients with colorectal cancer was 69.4% (867/1 250), and the incidence of postoperative anemia in patients with right colon cancer, left colon cancer, and rectal cancer was 81.8% (238/291), 68.9% (233/338), and 63.8% (396/621), respectively. Multivariate logistic regression analysis showed that age >60 years old, nutritional risk screening 2002 ≥3, right colon cancer, T3–4 stage, and M1 stage were risk factors for preoperative anemia in patients with colorectal cancer (P<0.05). The rate of intraoperative blood transfusion and the incidence of postoperative complications in the preoperative anemia group of patients with colorectal cancer were higher than those in the non-anemia group (P<0.05). The postoperative hospital stay in the preoperative anemia group of patients with colon cancer was longer than that in the non-anemia group (P<0.05).ConclusionsThe incidence of perioperative anemia in patients with colorectal cancer is high. Advanced age, high nutritional risk, right colon cancer, T3–4 stage, and distant metastasis were the risk factors of preoperative anemia in patients with colorectal cancer. Preoperative anemia can increase the demand for intraoperative blood transfusion and the incidence of postoperative complications in patients with colorectal cancer, and prolong postoperative hospital stay of colon cancer patients.
Objective To explore the current situation and influencing factors of self-management behavior in patients with primary glaucoma, so as to provide a theoretical basis for formulating intervention strategies to improve patients’ self-management ability. Methods Using convenient sampling method, 400 patients with primary glaucoma visiting the Outpatient Department of Ophthalmology, West China Hospital of Sichuan University between September 2019 and March 2020 were selected. Their current situation of self-management behavior was investigated by self-management behavior questionnaire, and the influencing factors of self-management behavior were analyzed. Results A total of 381 valid questionnaires were recovered. The total score of self-management behavior of patients with primary glaucoma was 51.11±6.22, and the mean scores of life debugging dimension, functional health care dimension, and medical management dimension were 2.66±0.67, 3.02±0.81, and 3.13±0.60, respectively. The results of multiple linear regression analysis showed that age [40-59 vs. <40 years old: unstandardized partial regression coefficient (b)=–2.830, 95% confidence interval (CI) (–4.813, –0.847), P=0.005; ≥60 vs. <40 years old: b=–2.660, 95%CI (–4.820, –0.498), P=0.016], occupation [in-service vs. farmers: b=2.639, 95%CI (0.303, 4.976), P=0.027; unemployed or retired vs. farmers: b=2.913, 95%CI (0.995, 4.831), P=0.003], smoking [smoking vs. non-smoking: b=–3.135, 95%CI (–5.196, –1.075), P=0.003], disease type [primary open-angle glaucoma vs. primary angle-closure glaucoma: b=–2.119, 95%CI (–3.317, –0.921), P=0.001], number of follow-up visits [≤2 vs. >2: b=–1.071, 95%CI (–2.118, –0.024), P=0.045], whether fixed doctor follow-up [unfixed vs. fixed: b=–2.619, 95%CI (–3.632, –1.605), P<0.001] were correlated with the total score of self-management behavior of patients with primary glaucoma. Conclusions The self-management behavior of patients with primary glaucoma is in the middle level. The main factors affecting the self-management behavior level of primary glaucoma patients include age, occupation, smoking, disease type, follow-up times, and fixed doctor’s follow-up. Ophthalmologists should pay attention to the current situation and influencing factors of self-management behavior and take feasible intervention measures to improve the self-management behavior of patients with primary glaucoma.
Objective To understand the incidence of frailty in maintenance hemodialysis (MHD) patients, and to explore the correlation and influencing factors of frailty in MHD patients, so as to provide some basis for the intervention of frailty in MHD patients. Methods Patients who underwent MHD in the Department of Nephrology of West China Hospital of Sichuan University from January to March 2021 were selected. Frail scale and Pittsburgh Sleep Quality Index (PSQI) were used for evaluation, and the influencing factors of frail in patients with MHD and its correlation with frail were analyzed. Results A total of 141 patients with MHD were included, including 57 cases without frailty (40.43%), 71 cases in early frailty (50.35%), and 13 cases in frailty (9.22%). 54 cases (38.30%) had very good sleep quality, 56 cases (39.72%) had good sleep quality, 24 cases (17.02%) had average sleep quality, and 7 cases (4.96%) had very poor sleep quality. The frailty of MHD patients was positively correlated with age (rs=0.265, P=0.002), PSQI (rs=0.235, P=0.005) and magnesium (rs=0.280, P=0.001). Logistic regression analysis showed that the influencing factors of MHD patients’ frailty were gender [odds ratio (OR) =4.321, 95%confidence interval (CI) (1.525, 12.243), P=0.006], PSQI [OR=1.110, 95%CI (1.009, 1.222), P=0.032], magnesium [OR=122.072, 95%CI (4.752, 3 135.528), P=0.004], hypertension [OR=0.112, 95%CI (0.023, 0.545), P=0.007] and other diseases [OR=0.102, 95%CI (0.019, 0.552), P=0.008]. Conclusions The incidence of frailty in MHD patients is high. Gender, PSQI, magnesium, hypertension and other diseases are the influencing factors of frailty in MHD patients, and there is a correlation between frailty and sleep. It is suggested that renal medical staff should pay more attention to the assessment of MHD frailty and sleep, and carry out multi-disciplinary personalized intervention to improve the quality of life of MHD patients.
ObjectiveTo explore value of ultrasound real-time elastography (RTE) technology for identification of benign and malignant solid thyroid nodules.MethodsA retrospective analysis was performed on 125 patients with thyroid nodules who underwent ultrasound RTE in this hospital from February 2018 to August 2019. All patients underwent RTE on the basis of conventional ultrasound. The ultrasound elasticity contrast index (ECI) was used as the evaluation index and the pathological examination result was used as the gold standard. The receiver operating characteristic (ROC) curve analysis was used to evaluate the value of ECI in the identification of benign and malignant solid thyroid nodules. Logistic regression analysis was used to analyze the influencing factors of ECI.ResultsAmong the 125 patients with solid thyroid nodules, 51 were malignant nodules, 74 were benign nodules. The ECI value of patients with benign thyroid nodules was lower than that of patients with malignant nodules (2.71±0.83 versus 3.42±1.14, t=–4.030, P<0.001). The result of ROC analysis showed that the cutoff value of ECI to distinguish benign and malignant solid thyroid nodules was 3.07, area under curve of ROC was 0.806 [95%CI (0.717, 0.894), P<0.001], sensitivity was 80.3%, specificity was 70.4%. The multivariate logistic regression analysis showed that the thyroid nodules with diffuse lesions, calcification, and maximum nodule diameter ≥1 cm were the risk factors for elevated ECI values (P<0.05). For the solid thyroid nodules without diffuse lesions, without calcification, and maximum nodule diameter <1 cm, ECI had the higher sensitivity, specificity, accuracy, and positive predictive value for the differential diagnosis of benign and malignant thyroid nodules (all exceed 80%), but these indexes were lower (under 60%) for the differential diagnosis of solid thyroid nodules with diffuse diseases, with calcification, and maximum nodule diameter ≥1 cm.ConclusionsECI obtained by ultrasound RTE can be used to differentiate solid thyroid nodules from benign ones. The presence or absence of diffuse lesions, calcification, and maximum nodule diameter are the influencing factors for ECI to differentiate solid thyroid nodules. In clinical diagnosis, it should be paid attention to the comprehensive analysis of the above factors.
Objective To review the influencing factors of medial patellofemoral ligament (MPFL) reconstruction for patellar dislocation. Methods The literature of MPFL reconstruction for patellar dislocation at home and abroad in recent years were summarized and analyzed. Results The influencing factors such as the location of the femoral insertion point, the tension and the fixed angle of the grafts, the dysplasia of the femoral trochlear before operation, the abnormal tuberositas tibiae-trochlear groove value, the high position of the patellar, and the tilting angle of the patellar, are all the factors affecting the effectiveness of MPLF reconstruction. Conclusion During MPFL reconstruction, the surgical techniques and elimination of other factors that caused patellar instability need to be focused in order to reduce the complications and operation failure.
