Abstract:

Summary

To position a safe gastric puncture point prior to the percutaneous endoscopic gastrostomy (PEG) a technique using an abdominal plain film with a gastric insufflation was assessed. After insufflated with 500 ml of air, an abdominal plain film was obtained before PEG in 84 patients. The body of the stomach near the angularis, equidistant from the greater and lesser curves, was defined as the optimal gastric puncture point. The location of the puncture points varied greatly, being situated over the right upper quadrant in 31% of patients, left upper in 59%, right lower in 5% and left lower quadrant in 5% of patients. The marked puncture points on abdominal film in some patients were shown to be partially covered by colon or small bowel loop, lie high under the costal margin, or low beneath the umbilicus. An abdominal plain film utilising a gastric insufflation technique prior to PEG may help to determine optimal gastric puncture site selection. Use this technique in clinical practice might hasten procedural time, provide better assurance to the clinical doctor, and provide an added margin of safety for the patient.
