Fluoroscopy-Guided Pull-Through Gastrostomy

The purpose of this study was to simplify a fluoroscopy guided gastrostomy technique using pull-type tubes which are traditionally introduced with gastroscopic assistance. The stomach was transorally probed with a 5-Fr catheter and a guidewire. A second access was performed percutaneously through the anterior abdominal and gastric wall using an 8-Fr sheath and an 8-Fr guiding catheter. A duplicated guidewire was introduced through the guiding catheter in order to result in a great custom-made loop within the stomach. The transoral guidewire was captured and tightened with this loop and the guiding catheter, and both were subsequently pulled by the transoral guidewire until the tip of the guiding catheter exited the mouth. A thread was fed through the guiding catheter for fixation of the pull-type gastrostomy tube. Finally, the fixed tube was pulled through the esophagus into the stomach and through the abdominal wall until the anterior gastric wall fixed the retention plate of the tube. Thirty-seven patients (28 male, 9 female; age, 65.1 ± 14.4 years) with miscellaneous indications for percutaneous gastrostomies were supplied with pull-type gastrostomy catheters in a fluoroscopy technique without endoscopic assistance. Twenty-five of the 37 patients (67.6%) had undergone unsuccessful preceding gastroscopically guided PEG attempts because of tumor stenosis (n = 12) or impossible transillumination of the abdominal wall (n = 13). All procedures were technically successful, without major complications. Particularly, all patients with frustrating gastroscopic attempts were successfully provided with pull-type gastrostomy tubes. Five minor complications occurred: one tube loss during the passage of the hypopoharynx because of a torn thread, one transient small leakage alongside the tube (both successfully treated), and three cases of transient moderate local pain without leakage (symptomatic treatment). We conclude that this fluoroscopy-guided pull-through gastrostomy technique is easy and safe to perform and may be suggested as a standard procedure for radiological gastrostomies. It combines the ease of the radiological approach with the advantages of the pull-type tube devices, particularly the benefits of the typical retention plates.
