Background Despite the widespread use of percutaneous endoscopic gastrostomy (PEG) tubes, their placement may be associated with a variety of complications, including gastrocolic fistula. Methods In total, 48 individuals underwent computed tomography-gastro-colonography (CT-GC)-guided PEG placement. Study end points included success of CT-GC, inability to thread the PEG tube, the eventual tube location, tube adjustments needed, adverse events, operating time, and PEG tube-related infection. Results A successful CT-GC was achieved in all 48 patients (100%), and we successfully used a standard PEG technique to place the gastrostomy tube in 44 patients (92%). In 4 patients (8%), the laparoscopic-assisted PEG technique was used because the transverse colon became interposed between the abdominal wall and the anterior wall of the stomach. The overall procedure-related minor complication rate was 8%. Conclusion CT-GC is an optional method for the estimation of intra-abdominal, anatomical orientations that may minimize the risk of complications before PEG placement.
