AbstractBackgroundGastrostomy tubes placed radiologically, endoscopically or surgically facilitate long‐term home enteral nutrition (HEN). Patient‐specific clinical factors may affect placement techniques, confounding direct comparisons between radiologically inserted gastrostomy (RIG) and percutaneous endoscopic gastrostomy (PEG) outcomes. This study sought to evaluate the differences in clinical outcomes in patients undergoing gastrostomy tube placement by interventional radiologists or gastroenterologists.MethodsA single‐center prospective trial randomizing patients initiating HEN to RIG or PEG was conducted between March 2018 and June 2021. Patients were followed until the time of gastrostomy removal or until 9 months after tube placement. Tracked complications included peritonitis, abscess, bleeding, bowel perforation, and tube occlusion, malposition, or damage. Periprocedural pain rating and quality of life (QoL) surveys were collected.ResultsForty‐two patients were randomized to RIG or PEG. Twenty patients underwent RIG (mean age, 63.0 ± 11.7 years; 85% male; 95% with head and neck cancer) and 22 patients underwent PEG (mean age, 66.3 ± 10.9 years; 81.8% male; 90.9% with head and neck cancer). RIG and PEG groups had 4.18 ± 5.49 and 2.80 ± 5.82 complications per 1000 HEN days, respectively (P = 0.357). The most frequent complications were tube malposition and abscess formation for the RIG and PEG groups, respectively. No major complications occurred in either group. There was no difference in the average of pain ratings in all pain inventory components across both groups. Both groups reported improvement in overall QoL after gastrostomy tube placement (P = 0.532).ConclusionRIG is noninferior to PEG regarding complication rates, pain, and QoL when compared in a prospective randomized fashion.

Background To review long-term outcomes and saphenous vein (SV) occlusion rate after endovenous ablation (EVA) for symptomatic varicose veins. Methods A review of our EVA database (1998–2018) with at least 3-years of clinical and sonographic follow-up. The primary end point was SV closure rate. Results 542 limbs were evaluated. 358 limbs had radiofrequency and 323 limbs had laser ablations; 542 great saphenous veins (GSV), 106 small saphenous veins (SSV) and 33 anterior accessory saphenous veins (AASV) were treated. Follow-up was 5.6 ± 2.3 years; 508 (74.6%) veins were occluded, 53 (7.8%) partially occluded and 120 (17.6%) were patent. On multivariable Cox regression analysis, male sex (HR 1.6, 95% CI [0.46–018], p = 0.012) and use anticoagulation (HR 2.0, 95% CI [0.69–0.34], p = 0.044) were predictors of long-term failure. On Kaplan-Meier curve, we had an 86.3% occlusion rate. Conclusion Our experience revealed a 5-year closure rate of 86.3%. Ablations have satisfactory occlusion rate.

This study examined the potential correlation between pulmonary embolism (PE) attenuation on computed tomography pulmonary angiography (CTPA) and pulmonary artery hemodynamic response to catheter-directed thrombolysis (CDT) in 10 patients with submassive PE. Treatment parameters, PE attenuation, clot burden, computed tomography signs of right ventricle dysfunction and right ventricular systolic pressure at echocardiography were retrospectively analyzed to determine correlation with pulmonary artery pressure improvement using Spearman correlation. A single reader, blinded to the treatment results, measured PE attenuation of all patients. There was a significant positive correlation between PE attenuation and absolute pulmonary artery pressure improvement with a Spearman correlation of 0.741, p=0.014. When attenuation was greater than or equal to the median (44.5 HU, n=5), CDT was associated with significantly better pulmonary artery pressure improvement ( p=0.037). Clot attenuation at CTPA may be a potential imaging biomarker for predicting pulmonary artery pressure improvement after CDT.
