Percutaneous radiologic gastrostomy (PRG) requires preliminary gastric inflation through a nasogastric tube (NGT) to safely perform gastric puncture. However, in case of pharyngeal or esophageal obstruction, NGT placement may be impossible even with a hydrophilic angiography catheter and wire. This brief report describes percutaneous computed tomography (CT)-guided gastrostomy with a 2-stick approach without nasogastric insufflation in 13 patients. Technical success rate was 100% with a mean of 1.8 punctures ± 1.0 to access the gastric lumen. Traversal of the colon and liver with a 22-gauge needle was necessary in 4 and 1 patients, respectively. There were no major complications. Minor complications occurred in 6 patients (46%). CT-guided percutaneous gastrostomy is technically feasible with minimal morbidity.
经皮放射胃造口术（PRG）需要通过鼻胃管（NGT）进行胃充气，以安全进行胃穿刺。然而，在咽部或食管梗阻的情况下，即使使用亲水性造影导管和导丝，NGT 放置也可能不可能。本简要报告描述了 13 例在未进行鼻胃管充气的情况下，使用 2 根穿刺针的经皮 CT 引导胃造口术。技术成功率为 100%，平均穿刺 1.8 次±1.0 次即可进入胃腔。4 例和 1 例患者分别需要用 22 号针穿过结肠和肝脏。无主要并发症。6 例（46%）患者出现轻微并发症。CT 引导下经皮胃造口术具有技术可行性，且并发症轻微。
