METHODS Clinical feature and colonoscopic findings of 156 MC patients were retrospectively analyzed. Final diagnosis of MC case was made after colonoscopic and pathological examination, and data of the case history was recorded. RESULTS The overall detection rate of MC was 1.12%, with 0.46% in males, 0.66% in females. An 82.69% of the patients suffered various constipations and had a history of taking cathartics. The clinical manifestation of total-colon melanosis occurred in 83.97% of the patients. There was no significant difference between the rate of concomitant polypus （27.56%） in the MC patients and the detection rate of polypus in the patients who underwent a synchronous colonoscopy （χ^2 = 1.205, P = 0.298）. Also there was no significant difference between the detection rate of carcinoma of the large intestine （8.97%） in MC patients and the detection rate of the same disease in the patients who underwent synchronous colonoscopy （χ^2 = 0.268, P = 0.604）. A logistic regression analysis has shown that the older the age of MC patients is, the more opportunities of MC and the concomitant polypus would occur. CONCLUSION MC may be related to constipations and a long-term administration of cathartics, among which total-colon melanosis ranks first in the cases. There is an earlier age of onset in the females, with a higher detection rate. The older the age of the patients is, the higher the detection rate of MC is, and the more possibility the onset of the concomitant polypus.展开更多

文摘OBJECTIVE To investigate the clinical characteristics of melanosis of the colon （MC） and its correlation with polypus and carcinoma of the large intestine. METHODS Clinical feature and colonoscopic findings of 156 MC patients were retrospectively analyzed. Final diagnosis of MC case was made after colonoscopic and pathological examination, and data of the case history was recorded. RESULTS The overall detection rate of MC was 1.12%, with 0.46% in males, 0.66% in females. An 82.69% of the patients suffered various constipations and had a history of taking cathartics. The clinical manifestation of total-colon melanosis occurred in 83.97% of the patients. There was no significant difference between the rate of concomitant polypus （27.56%） in the MC patients and the detection rate of polypus in the patients who underwent a synchronous colonoscopy （χ^2 = 1.205, P = 0.298）. Also there was no significant difference between the detection rate of carcinoma of the large intestine （8.97%） in MC patients and the detection rate of the same disease in the patients who underwent synchronous colonoscopy （χ^2 = 0.268, P = 0.604）. A logistic regression analysis has shown that the older the age of MC patients is, the more opportunities of MC and the concomitant polypus would occur. CONCLUSION MC may be related to constipations and a long-term administration of cathartics, among which total-colon melanosis ranks first in the cases. There is an earlier age of onset in the females, with a higher detection rate. The older the age of the patients is, the higher the detection rate of MC is, and the more possibility the onset of the concomitant polypus.

文摘BACKGROUND Gastric cancer is a malignancy with high morbidity and mortality rates.Surgical intervention,particularly gastrectomy,is essential for curative treatment but carries a substantial risk of complications.Identifying key risk factors and understanding complication profiles are crucial for improving outcomes and guiding perioperative management.AIM To analyze the incidence of postoperative complications in patients with gastric cancer and identify potential risk factors.METHODS We conducted a retrospective analysis of 500 patients who underwent gastrectomy between January 2018 and December 2022.Postoperative complications were classified using the Clavien-Dindo system.RESULTS The overall complication rate was 28.4%(142/500),with 15.2%(76/500)experiencing major complications(Clavien-Dindo grade≥III).Pulmonary complications were the most frequent(10.8%),followed by surgical site infections(8.6%),and anastomotic leakage(4.2%).Age 70 years or more,body mass index of 25 kg/m²or more,advanced tumor stage,total gastrectomy,and operative time 240 min or more emerged as independent risk factors.CONCLUSION Focused preoperative risk assessment,targeted interventions,and reduced operative time for older or obese patients requiring total gastrectomy or presenting with advanced disease are important to improve surgical outcomes.
文摘Objective To compare the effect of patient positioning on bronchoscopy-guided bronchoalveolar lavage(BAL)recovery rate and to inform position selection in clinical practice.Methods A retrospective study was conducted using routine BAL records from 2019 to 2024 at a single center.Four position groups were analyzed(n=110 each):supine,lateral nondependent(target lung up),lateral dependent(target lung down),and prone.The primary outcome was recovery rate(%).Distributional assumptions were evaluated with the Shapiro-Wilk test and Levene's test.Group differences were assessed by one-way analysis of variance(ANOVA);pairwise post-hoc comparisons used Welch's t test with mean differences and 95%confidence intervals(CI).A linear regression model adjusted for lobar site was used to estimate lobe-adjusted marginal means by position.Results Mean(x±SD)recovery rates were:supine 52.08±7.70%,lateral nondependent 62.66±8.27%,lateral dependent 45.98±8.50%,prone 55.12±7.59%.Between-group differences were significant(ANOVA F=82.14,P<0.001).Lobe-adjusted marginal means were directionally consistent with unadjusted results.Conclusions Patient position is significantly associated with BAL recovery.When clinically feasible and safe,placing the target lung in the nondependent position yields higher recovery rates.
文摘BACKGROUND Patients who undergo radical cervical cancer surgery often experience sexual dysfunction and psychological distress,which seriously affects their quality of life.This study aimed to evaluate the clinical effectiveness of mindfulness-based stress reduction(MBSR)therapy for psychosexual adaptation in patients after radical cervical cancer surgery.AIM To systematically evaluate the clinical effectiveness of MBSR therapy on psychosexual adaptation in patients following radical cervical cancer surgery.METHODS A multicenter retrospective study design was used to analyze the clinical data of 280 patients who underwent radical cervical cancer surgery between January 2021 and August 2024 at Lishui Central Hospital,The Fifth Hospital Affiliated to Wenzhou Medical University,Lishui Hospital of Zhejiang University and Wenzhou Central Hospital.Patients were divided into an intervention group(n=140;receiving standard MBSR intervention)and a control group(n=140;receiving only routine care and sexual health guidance).Among these,140 cases were collected from Lishui Central Hospital,The Fifth Hospital Affiliated to Wenzhou Medical University,Lishui Hospital of Zhejiang University(70 in the intervention group and 70 in the control group)and Wenzhou Central Hospital(70 in the intervention group and 70 in the control group).RESULTS After intervention,patients in the MBSR intervention group showed significant improvement in anxiety and depression levels(anxiety:5.8±1.2 vs 8.3±1.7,P<0.001;depression:6.2±1.4 vs 9.1±1.8,P<0.001).The proportion of patients with clinically significant anxiety decreased from 69.3%to 21.4%(control group:67.9%-52.9%,P<0.001).The intervention group showed significantly better Female Sexual Function Index total scores(23.5±3.6 vs 17.8±3.2,P<0.001)and scores in all dimensions than the control group,with a significantly lower incidence of sexual dysfunction(42.9%vs 67.9%,P<0.001).Regarding sexual relationship satisfaction,both patients in the intervention group(78.3±6.5 vs 65.2±7.8,P<0.001)and their partners(76.9±7.1 vs 63.6±8.3,P<0.001)showed significantly improved scores.Age-stratified analysis showed that MBSR was most effective in younger patients(≤45 years,46-55 years;P<0.001),with relatively less benefit in older patients(>55 years;P=0.032).Multivariate regression analysis confirmed that MBSR intervention[odds ratios(OR)=2.86,95%confidence interval(95%CI):1.75-4.68,P<0.001]and partner support(OR=1.92,95%CI:1.28-2.87,P=0.002)were independent positive predictive factors for improving patients'psychosexual adaptation.CONCLUSION MBSR therapy can effectively improve anxiety and depression in patients after radical cervical cancer surgery and significantly enhance sexual function and sexual relationship satisfaction,with the effects being more pronounced in younger patients.This study demonstrated that MBSR,as an integrative intervention approach,has independent positive effects on psychosexual adaptation in post-operative cervical cancer patients and is worthy of promotion in clinical practice.
文摘BACKGROUND Endoscopic retrograde cholangiopancreatography is a challenging procedure involving bile duct cannulation.Despite the development of several cannulation devices,none have effectively facilitated the procedure.AIM To evaluate the efficacy of a recently developed catheter for bile duct cannulation.METHODS We retrospectively examined 342 patients who underwent initial cholangiopan-creatography.We compared the success rate of bile duct cannulation and the incidence of complications between the groups using existing and novel catheters.RESULTS The overall success rates of bile duct cannulation were 98.3%and 99.1%in the existing and novel catheter groups,respectively(P=0.47).The bile duct cannulation rate using the standard technique was 73.0%and 82.1%in the existing and novel catheter groups,respectively(P=0.042).Furthermore,when catheterization was performed by expert physicians,the bile duct cannulation rate was significantly higher in the novel catheter group(81.3%)than in the existing catheter group(65.2%)(P=0.017).The incidence of difficult cannulation was also significantly lower in the novel catheter group(17.4%)than in the existing catheter group(33.0%)(P=0.019).CONCLUSION The novel catheter improved the bile duct cannulation rate using the standard technique and reduced the frequency of difficult cannulation cases,valuable tool in endoscopic retrograde cholangiopancreatography procedures performed by experts.

文摘BACKGROUND Postoperative pulmonary complications(PPCs)are the most common complications following major upper abdominal surgeries,particularly hepatobiliary procedures,and significantly compromise surgical outcomes and patients’quality of life.Although the adoption of laparoscopy has lowered their incidence,PPCs remain a frequent and serious concern after hepatobiliary surgery.Existing research on risk factors specific to hepatobiliary surgeries is limited,particularly regarding the epidemiology and risk factors of PPCs in liver and gallbladder surgeries in China.Therefore,this study aimed to investigate the risk factors for PPCs in a large hepatobiliary center.AIM To identify the incidence and risk factors for PPCs following hepatobiliary surgery based on perioperative variables.METHODS Retrospective data were collected from patients who underwent liver,gallbladder,or pancreatic surgery at a hepatobiliary center in China between May 2023 and December 2023.We retrospectively reviewed comprehensive medical records to extract demographic and hospital admission information for determining PPC incidence.Statistically significant variables were initially screened through univariate analysis,followed by binary logistic regression modeling to identify independent predictors of PPCs.Hospitalization expenditures and duration of stay were further contrasted across the study cohorts.RESULTS This study included 1941 patients who underwent liver,gallbladder,or pancreatic surgery,of whom 78 developed PPCs,resulting in an incidence rate of 4.02%.Logistic regression analysis revealed two independent predictors of PPCs in hepatobiliary surgery patients:Age≥75 year(odds ratio=8.350,95%CI:3.521-19.798,P<0.001)and prolonged anesthesia(odds ratio=1.052,95%CI:1.015-1.091,P=0.006).Patients with PPCs had significantly elevated healthcare resource utilization,including higher total hospitalization costs,increased medication expenses,longer hospital stays,and extended postoperative admissions(all P<0.001).CONCLUSION Age≥75 years and prolonged anesthesia emerged as independent predictors of PPCs following hepatobiliary surgery.These complications were correlated with protracted hospitalization and increased healthcare costs.
文摘BACKGROUND Gastric cancer(GC)poses a significant threat to public health.However,the clinicopathological features and tumor biological behaviors vary among the GC patients,leading to individual variations in lymph node metastasis.Consequently,the stratification of lymph node dissection according to the specific type,particularly upper GC,has emerged as a prominent area of research.AIM To investigate the distribution of metastatic lymph nodes in patients with upper and lower GC and to analyze the differences in related pathological elements and prognosis.METHODS Differential analysis between upper and lower GC patients with various clinicopathological factors was performed using the chi-square test and rank-sum regression models were used to analyze risk factors affecting patient prognosis.The Kaplan-Meier method was used to construct survival curves associated with prognostic risk factors for GC.RESULTS Significant differences were observed between the two GC populations regarding tumor diameter,histological grade,pT stage,pN stage,tumor-node-metastasis(pTNM)stage,vascular invasion,and adjuvant chemotherapy usage(all P<0.05).Lymph node metastasis rates were highest for Siewert type II patients in groups Nos.1,3,2 and 7;for Siewert type III patients in groups Nos.3,1,2 and 7;and for other/unclassified patients in groups Nos.1,3,7,2.In the lower GC samples,the sequences were Nos.3,6,7,4.Pathological type,pT stage,pTNM stage,and positive vascular invasion were independent risk factors for development of lymph node metastasis.Age,pathological type,pT stage,pN stage,pTNM stage,vascular invasion,and absence of adjuvant chemotherapy were identified as independent prognostic factors.CONCLUSION Upper GC showed a significantly higher malignancy grade and different lymph node metastasis pattern than lower GC.
文摘BACKGROUND Post-operative infection is a common and serious complication following drugeluting trans arterial chemo embolization(D-TACE)in patients with hepatocellular carcinoma(HCC),potentially compromising treatment efficacy and increasing morbidity.AIM To investigate the risk factors associated with post-operative infection in HCC patients undergoing D-TACE,and to provide evidence for clinical prevention and targeted intervention strategies.METHODS Clinical data of 77 primary HCC patients who underwent D-TACE in our hospital from January 2022 to December 2023 were retrospectively analyzed.Patient demographics,laboratory test results,tumor characteristics,and surgery-related parameters were collected.Univariate and multivariate logistic regression analyses were performed to identify risk factors for post-operative infection.RESULTS Post-operative infection occurred in 20 cases(25.97%)among the 77 patients.Univariate analysis showed that age≥65 years,Child-Pugh grade B,tumor diameter≥5 cm,operation time≥120 minutes,preoperative albumin<35 g/L,and comorbid diabetes were significantly associated with post-operative infection(P<0.05).Multivariate logistic regression analysis identified Child-Pugh grade B(OR=2.851,95%CI:1.426-5.698),operation time≥120 minutes(OR=2.367,95%CI:1.238-4.523),and preoperative albumin<35 g/L(OR=2.156,95%CI:1.147-4.052)as independent risk factors for post-operative infection.CONCLUSION Liver function status,operation time,and preoperative albumin level are significant factors affecting post-operative infection in HCC patients undergoing D-TACE.For high-risk patients,enhanced perioperative management,appropriate timing of surgery,and active improvement of nutritional status should be implemented to reduce the risk of post-operative infection.
文摘Objective To develop and validate a preoperative clinical-radiomics model for predicting overall survival(OS)and disease-free survival(DFS)in patients with extrahepatic cholangiocarcinoma(eCCA)undergoing radical resection.Methods In this retrospective study,consecutive patients with pathologically-confirmed eCCA who underwent radical resection at our institution from 2015 to 2022 were included.The patients were divided into a training cohort and a validation cohort according to the chronological order of their CT examinations.Least absolute shrinkage and selection operator(LASSO)-Cox regression was employed to select predictive radiomic features and clinical variables.The selected features and variables were incorporated into a Cox regression model.Model performance for 1-year OS and DFS prediction was assessed using calibration curves,area under receiver operating characteristic curve(AUC),and concordance index(C-index).Results This study included 123 patients(mean age 64.0±8.4 years,85 males/38 females),with 86 in the training cohort and 37 in the validation cohort.The OS-predicting model included four clinical variables and four radiomic features.It achieved a training cohort AUC of 0.858(C-index=0.800)and a validation cohort AUC of 0.649(C-index=0.605).The DFS-predicting model included four clinical variables and four other radiomic features.It achieved a training cohort AUC of 0.830(C-index=0.760)and a validation cohort AUC of 0.717(C-index=0.616).Conclusion The preoperative clinical-radiomics models show promise as a tool for predicting 1-year OS and DFS in eCCA patients after radical surgery.
文摘BACKGROUND Cholecystectomy is a common surgical procedure routinely performed for patients with benign gallbladder disease.The most common indications for cholecystectomy are acute or chronic cholecystitis with or without cholelithiasis.However,in rare instances,incidental findings ranging from benign to malignant conditions are encountered,of which gallbladder adenocarcinoma is an aggre-ssive and fatal disease.AIM To determine the prevalence of all incidental diagnoses in routinely performed cholecystectomy specimens,with a particular emphasis on adenocarcinoma,and to characterize the clinicopathological characteristics of malignant postoperative specimens.METHODS The electronic medical record and institutional pathology database were searched for analyses done on gallbladder specimens from patients who had a routine cholecystectomy for benign gallbladder disease during the study period(February 2000 to February 2023).A total of 30678 cholecystectomies performed across the study period were included for analysis.Patients who had preoperative findings or radiological results concerning malignancy were excluded.The demographic and clinical data including patient age and gender,preoperative diagnosis,ra-diographic results at time of diagnosis,gross and morphologic features of gallbladder specimens,and pathologic staging parameters according to the American Joint Committee on Cancer were recorded.RESULTS Of the 30678 cholecystectomy specimens received by the Department of Pathology from patients with who had cholecystectomy for putative benign gallbladder disease during the study period,42(0.14%)were determined to be incidental gallbladder adenocarcinoma and 1 was adenocarcinoma in situ.There were 2 benign incidental dia-gnoses,including 9 patients(0.02%)with accessory/ectopic liver lobe,and 3 with paraganglioma.CONCLUSION Thorough histopathological examination of routine gallbladder specimens is important to provide an early diagnosis of unexpected gallbladder cancer to ensure that patients receive timely care when the disease is treatable.

文摘BACKGROUND Gastric signet-ring cell carcinoma(GSRCC)is a more aggressive subtype of gastric cancer compared to gastric adenocarcinoma(GA),with an increasing incidence.However,the prognostic differences between these subtypes,particularly in re-sectable cases,remain unclear.AIM To evaluate prognostic factors and develop a predictive model for GA and GSRCC patients undergoing curative resection.METHODS This retrospective cohort study included patients with GA and GSRCC who underwent curative surgery at the National Cancer Center/Cancer Hospital,Chinese Academy of Medical Sciences,from 2011 to 2018.Propensity score ma-tching(PSM)(1:1)balanced the baseline characteristics.Prognostic factors were identified using univariate and multivariate Cox and least absolute shrinkage and selection operator(LASSO)regression analyses.Model performance was eva-luated through calibration curves,decision curve analysis(DCA),and time-dependent receiver operating characteristic curves.Subgroup analysis and Ka-plan-Meier survival curves were generated.RESULTS In a cohort of 3027 patients,the GSRCC group was characterized by a significantly higher prevalence of individuals under 60 years of age,females,cases with poor differentiation,and early-stage(stage I)disease(all P<0.001).After PSM,the baseline was balanced and 761 patients were retained in each group.Variables identified through univariate Cox regression were included in the LASSO regression analysis.Mul-tivariate Cox regression analysis identified age,tumor differentiation,tumor size,vascular invasion,and post-treatment nodal margin staging as independent prognostic factors.Subgroup analysis indicated a notably poorer prognosis for GSRCC in patients aged 60 and above(hazard ratio=1.36,P=0.025).The nomogram(C-index=0.755)exhibited greater predictive accuracy than tumor node metastasis(TNM)staging for 1-,3-,and 5-year overall survival(all P<0.001),and provided a higher clinical net benefit according to DCA.CONCLUSION This study systematically compared resectable GA and GSRCC,revealing no overall survival difference.However,GSRCC demonstrated a significantly elevated mortality risk in subgroups stratified by age and tumor size.Multivariate analysis identified age,differentiation,tumor size,vascular invasion,and TNM stage as independent prognostic factors.The nomogram integrates clinicopathological features for precise risk stratification,surpassing traditional TNM staging.
文摘BACKGROUND The neurological and psychiatric sequelae of coronavirus disease 2019(COVID-19)have been documented,yet further data are needed to thoroughly evaluate the impact of COVID-19 on brain health years after the infection.AIM To examine whether COVID-19 infection is associated with exacerbation,recurrence,or progression of pre-existing neurological or psychiatric disorders-a highrisk population that is underrepresented in COVID-19 outcome research in National Guard Health Affair patients in 4-years following a COVID-19 diagnosis.METHODS For this multicenter retrospective cohort study,we used data from the National Guard hospitals electronic health records network(BestCare)with over 10 million patients.Our cohort comprised patients who had a COVID-19 diagnosis;a matched control cohort included patient did not expose to COVID-19 in same period.Age and sex were matching factors.We estimated the incidence of 14 neurological and psychiatric outcomes in nearly 4 years after a confirmed diagnosis of COVID-19.Using a multiple logistic regression,we compared incidences with those in propensity score-matched cohorts of patients with no exposure to COVID-19.Ramadan M et al.Neurological and psychiatric risks post-COVID-19 RESULTS Our primary cohort comprised 4437 patients diagnosed with COVID-19,and our propensity-score 1:1 matched control cohort comprised 4437 individuals.Nearly two-third of the COVID-19 cohort(71%)were diagnosed in 2020,and 2021.The most prevalent diagnoses for both cohorts were epilepsy 30.68%,mood disorder 23.92%,and nerve plexus disorder 22.13%.Dementia was nearly 4 times higher among COVID-19 cohort(8.27%)compared to the control cohort(2.57%).Five neurological and psychiatric outcomes had odds ratios(OR)that were significantly higher than 1 for people who had COVID-19 compared to people who had never been infected.These outcomes were cognitive deficit OR=1.54,95%confidence interval(CI):1.23-1.91,P=0.0001;nerve plexus disorder OR=1.13,95%CI:1.01-1.25,P=0.02;substance use disorder OR=1.95,95%CI:1.12-3.38,P=0.01;mood disorder OR=1.16,95%CI:1.05-1.29,P=0.003;and anxiety disorder OR=1.39,95%CI:1.07-1.79,P=0.01.CONCLUSION The study highlights the persistent risk of neurological and psychiatric conditions in COVID-19 survivors up to four years post-infection.Although the incidence was lower than in previous large studies,long-term consequences remain significant,emphasizing the need for ongoing monitoring and support in mental health and neurological care.
