Sequential axial enhanced (a–c) and unenhanced (d) CT images demonstrate insufficient punction fields yielding unsuccessful CT-PG insertions in 4 patients: (a) Colonic interposition (arrow) ventral to the stomach (star); (b) Hiatus hernia (star); (c,d) the endoscopically inserted PEG tube is located in the gastric lumen (white star) and passes through the liver (triangle) as a complication of the previous endoscopic insertion. After paracentesis, insufficient punction field due to hepatomegaly (triangle) and colonic interposition (arrow) in the same patient; (e,f) presence of excessive haemorrhagic ascites (black star) despite multiple paracentesis and drainage (arrow).
