Abstract Background Percutaneous endoscopic gastrostomy (PEG) and percutaneous radiologic gastrostomy (PRG) are used for gastric drainage, decompression, and feeding. Recent innovations enable bumper and balloon‐type tube placement via transabdominal approach under guidance of fluoroscopy or sonography. Method This is a single‐center retrospective cohort study to evaluate the outcomes of balloon and bumper gastrostomy tube placement under guide of fluoroscopy and ultrasound. The total sample size was 470 consecutive patients. The eligibility criteria included all patients aged ≥18 years who underwent a balloon or bumper‐type gastrostomy tube insertion for nutrition support in both the interventional radiology unit and at the bedside between 2017 and 2022. Result This study revealed no significant differences between the two types of tubes in terms of time to tube replacement or requiring a gastrostomy tube. There was a positive correlation between the time that a patient has a gastrostomy tube and major complications ( P = 0.005) and a positive correlation between number of tubes replaced and minor complications ( P < 0.001). Both types of tubes were associated with low rates of complications. However, patients with a balloon tube were more likely to experience gastric‐tube–related hospitalization/ED visits and require a >24‐h hospital stay postoperation. Conclusion These findings can help healthcare providers make informed decisions when selecting the appropriate type of tube for their patients to have more durability with less complication.

Background The choice of angiography system could influence the outcomes of mechanical thrombectomy (MT) in the treatment of acute ischemic stroke (AIS), but its impact is not yet well understood. This study aims to compare the clinical and technical outcomes of MT performed with single plane versus biplane angiography systems. Method We conducted a systematic review and meta-analysis, following PRISMA guidelines, by searching PubMed, Embase, Web of Science, and Scopus to include studies on patients with AIS who underwent MT with either single plane or biplane angiography up to May 4, 2024. The primary outcome was a favorable outcome defined as a modified Rankin Scale (mRS) score of 0–2 at 90 days after the procedure. Data were analyzed using a random-effects model and heterogeneity was assessed using the I2 test and Q statistics. Results Five studies with a total of 1562 patients were analyzed. Of these, 68.4% were treated with biplane systems and 31.6% with single plane systems. Single plane angiography was associated with a significantly higher rate of favorable outcomes (OR 1.43; 95% CI 1.13 to 1.80; P<0.01). There were no significant differences in successful recanalization, periprocedural complications, procedure time, total fluoroscopy time, or contrast volume between the two systems. Conclusion While single plane angiography systems may offer slightly better outcomes in MT for AIS, both systems appear equally effective in most clinical and technical perspectives, suggesting that system selection may be more dependent on availability and procedural requirements rather than inherent superiority. Our findings may encourage clinicians to use single-plane angiography in settings where the biplane angiography suite availability is limited, but it should be noted that this observation may have been influenced by selection bias, particularly since the larger studies included in our meta-analysis did not observe this effect in adjusted analyses for potential confounder factors.

AbstractBackground and PurposeThe Alberta Stroke Program Early CT Score (ASPECTS) is a widely used scoring system for evaluating ischemic stroke to determine therapeutic strategy. However, there is variation in the interobserver agreement of ASPECTS. This systematic review and meta‐analysis aimed to investigate the interobserver agreement of total and regional ASPECTS.MethodsA comprehensive search was conducted in the Web of Sciences, PubMed, and Scopus databases to identify relevant studies. Inclusion criteria were studies of noncontrast CT performed within 24 hours of ischemic stroke in the middle cerebral artery territory.ResultsA total of 20 studies, with 3482 patients, reporting interobserver agreement of total and regional ASPECTS were included in the meta‐analysis. The interobserver agreement for total ASPECTS in studies using Kappa coefficient (κ) analysis was substantial (κ = .67, 95% confidence interval [CI]: .57‐.78). In studies using intraclass correlation coefficient (ICC) analysis, agreement was excellent (ICC = .84, 95% CI: .77‐.90). Interobserver agreement was higher in studies in which the observer was unblinded to clinical scenario in both groups (κ = .74, 95% CI: .59‐.89, and ICC = .82, 95% CI: .79‐.85). Per‐region analysis showed that the caudate nucleus had the highest agreement (κ = .68, 95% CI: .60‐.76, and ICC = .84, 95% CI: .74‐.93), while M2 and internal capsule in Kappa studies (κ = .45, 95% CI: .34‐.55 and κ = .47, 95% CI: .28‐.66), and M4 and internal capsule in ICC studies (ICC = .54, 95% CI: .43‐.64 and ICC = .55, 95% CI: .18‐.91) had the lowest agreement.ConclusionThis meta‐analysis demonstrates substantial to excellent interobserver agreement for total ASPECTS, which supports using this method for stroke treatment. However, findings emphasize the need to consider interobserver agreement in specific regions of ASPECTS for treatment decisions.
