Objective:To explore the diagnostic value of routine magnetic resonance imaging (MRI) findings for early detection of dural arteriovenous fistulas (DAVF).Methods:A retrospective collection of 53 patients with DAVF confirmed by digital subtraction angiography (DSA) at the Affiliated Hospital of Qingdao University from September 2018 to June 2023 was conducted. All patients underwent routine non-enhanced and enhanced MRI scans before treatment, with 30 patients also receiving magnetic resonance angiography (MRA) examination. Medical records were reviewed, and basic patient information, clinical symptoms, and imaging markers [pial venous engorgement (PVE), cerebral hemorrhage, subarachnoid hemorrhage, vasogenic edema, venous infarction, medullary veins engorgement (MVE), parenchymal enhancement, encephalopathy mimics] were recorded. The Cognard grading was carried out in accordance with the manifestations shown by DSA.Results:Seventy-seven percent (41/53) of patients exhibited PVE on the brain surface, with 95% (39/41) of these cases showing localized PVE on one hemisphere or even within a single brain lobe. Approximately 64% (34/53) of these PVEs were detectable on conventional T 2-weighted imaging. Among the 30 patients who underwent MRA, only 50% (15/30) showed evidence of PVE on both T 2WI and MRA, while an additional 23% (7/30) had PVE only on MRA. About 38% (20/53) of patients presented with isolated vasogenic edema, with 70% (14/20) of these cases demonstrating PVE on T 2WI. Twenty-six percent (14/53) of patients had intracranial hemorrhage, and 11 of these patients demonstrated positive signs of PVE. Parenchymal enhancement was primarily observed in subarachnoid structures in 11% (6/53) of patients, with 5/6 showing PVE on the brain surface or spinal cord surface. Venous infarction (4%, 2/53) and MVE (4%, 2/53) were more commonly seen in high Cognard grade DAVF, whereas encephalopathy mimics (4%, 2/53) were frequently encountered in low Cognard grade DAVF. Conclusions:PVE on the brain surface is a direct sign for the diagnosis of DAVF on routine MRI, yet it is often subtle. Familiarity with common indirect signs is of great importance for the early diagnosis of DAVF.

Objective:This multicenter retrospective study aimed to analyze the clinicopathological features of duodenal adenocarcinoma (DA) and identify prognostic factors for postoperative survival.Methods:Demographic characteristics, clinicopathological features, treatment outcomes and survival of DA patients undergoing surgical treatment at 18 Chinese medical centers from January 2012 to December 2023 were retrospectively analyzed.Results:Among the 2 056 DA patients included, 46.8% (963) had extra-ampullary DA (EA-DA), and 53.2% (1 093) had peri-ampullary DA (PA-DA). The 1-, 3-, and 5-year overall survival (OS) rates for patients who underwent radical surgery were 93.2%, 71.0%, and 57.2%, respectively. The median overall survival was 76 months, and the median progression-free survival (PFS) was 65 months. No differences in survival were observed between the laparotomy group and minimally invasive surgery (MIS) group either before or after propensity score matching (OS: 76 vs. 75 months before PSM, P=0.986; OS: 75 vs. 75 months after PSM, P=0.602). Furthermore, there were no significant differences between-group in operation time and postoperative complications ( P>0.05). The MIS group experienced less intraoperative blood loss and shorter hospital stays. The multivariate Cox regression analysis revealed that advanced age ( HR=1.43,95% CI:1.18-1.73), elevated carbohydrate antigen 19-9 levels ( HR=1.24,95% CI:1.02-1.51), perineural invasion ( HR=1.44,95% CI:1.14-1.81), vascular invasion ( HR=1.35,95% CI:1.07-1.71), advanced T stage (T3-4 vs. T1-2: HR=1.86,95% CI:1.49-2.31), regional lymph node metastasis ( HR=1.93,95% CI:1.58-2.36), preoperative biliary drainage ( HR=1.26,95% CI:1.04-1.53), intraoperative blood loss ( HR=1.34,95% CI:1.11-1.62), clinically significant postoperative pancreatic fistulas ( HR=1.53,95% CI:1.12-2.09), and postoperative hemorrhage ( HR=1.62,95% CI:1.14-2.29) were independent risk factors for poor prognosis after surgery (all P<0.05). Conclusions:Radical surgery is associated with favorable overall survival among DA patients, and no difference in survival is observed between EA-DA and PA-DA patients. MIS is a reliable alternative for DA treatment.

Objective:To evaluate the safety and efficacy of laparoscopes adhesiolysis in the treatment of adhesive intestinal obstruction.Methods:A retrospective analysis was conducted on the clinical data of 30 patients with adhesive intestinal obstruction who underwent laparoscopes adhesiolysis at the First Affiliated Hospital, Zhejiang University School of Medicine between January 2021 and December 2024. The demographics, surgical parameters and postoperative complications were recorded.Results:Among the 30 patients, 16 were male and 14 were female, with age of (55.93 ± 13.83) years. A history of abdominal surgery was present in 25 patients (83.3%). Of the surgeries, 4 cases (13.3%) were performed as emergency procedures and 26 cases (86.7%) were elective. The operative time was (125.57 ± 48.25) min, and intraoperative blood loss was (26.17 ± 16.90) ml. The time to first flatus was (3.30 ± 1.95) d, the time to first oral intake was 4.00 (3.00, 5.00) d, the hospital stay was (24.23 ± 17.97) d, and the postoperative hospital stay was 11.50 (6.75, 18.75) d. The incision pain score 0 score was in 8 cases (26.7%), 1 score in 5 cases (16.7%), 2 scores in 10 cases (33.3%), 3 scores in 3 cases (10.0%), 4 scores in 3 cases (10.0%), and 5 scores in 1 case (3.3%). One case developed a postoperative wound infection. The patients were followed up for 1 year, 1 patient experienced recurrent incomplete intestinal obstruction due to widespread peritoneal metastasis from gastric cancer.Conclusions:Laparoscopes adhesiolysis is a safe and effective treatment for adhesive intestinal obstruction, offering advantages in terms of postoperative recovery and low complication rates. The continued use of minimally invasive techniques is recommended in the management of this condition.

Objective:To examine the interaction between gender and the visceral adiposity index (VAI) in relation to the risk of type 2 diabetes mellitus (T2DM).Methods:This retrospective cohort study utilized data from the public Dryad database derived from the NAGALA (NAFLD in the Gifu Area, Longitudinal Analysis) project (1994-2016). Participants were stratified into quartiles based on VAI levels. A multivariate Cox proportional hazards regression model was employed to evaluate whether VAI independently predicts T2DM risk. Kaplan-Meier survival curves and receiver operating characteristic (ROC) curves were constructed for each VAI quartile. Subgroup analyses were conducted to examine associations across age and body mass index categories. Both multiplicative and additive interaction effects between gender and VAI were assessed. Additionally, gender-specific Cox models were fitted to further explore these associations.Results:A total of 15 453 participants [8 419 males and 7 034 females; mean age, (43.7±8.9) years] were included, with a median follow-up duration of 5.39 years. During follow-up, 373 participants (2.4%) developed T2DM. After adjustment for potential confounders, higher VAI levels were independently associated with increased T2DM risk ( HR=1.16; 95% CI 1.11-1.21), consistent with the results across VAI quartiles. Kaplan-Meier analysis revealed a significant trend of increasing T2DM incidence across VAI quartiles ( P<0.001). The area under the ROC curve for VAI in predicting T2DM at 3, 5, and 10 years was 0.755, 0.735, and 0.696, respectively. Sensitivity analyses showed that elevated VAI was associated with increased T2DM risk across all age and body mass index subgroups (all P<0.05). Regarding interaction analysis, the HR (95% CI) for the multiplicative interaction between VAI and gender was 1.22 (1.19-1.26). The relative excess risk of interaction was -1.08 (95% CI -2.96 to -0.06), the attributable proportion of interaction was -0.54 (95% CI -1.35 to -0.01), and the synergy index was 0.48 (95% CI 0.26-0.91), indicating a negative additive interaction. Using low-VAI women as the reference group, the risk of T2DM in high-VAI women was higher ( HR=2.53, 95% CI 1.59-4.02) compared to high-VAI men ( HR=2.01, 95% CI 1.49-2.72). In gender-specific analyses, increasing VAI remained significantly associated with elevated T2DM risk after adjustment in both females ( HR=1.43, 95% CI 1.21-1.68) and males ( HR=1.16; 95% CI 1.11-1.22), with consistent findings across VAI quartiles. Conclusions:VAI and gender demonstrated multiplicative and additive interaction in relation to T2DM risk. The association between increasing VAI and T2DM risk was more pronounced in women than in men.
