Fig. 1B. 44-year-old man with gastrocolic fistula and migration of
feeding tube into transverse colon as complication of percutaneous endoscopic
gastrostomy (PEG). Frontal spot image from radiographic study with
water-soluble contrast material (diatrizoate meglumine and diatrizoate sodium
[Gastroview]; Mallinckrodt) shows tip of tube in lumen of transverse colon
(black arrow denotes mushroom at end of tube) with antegrade colonic
filling to splenic flexure and retrograde filling of proximal transverse
colon. A thin track (long white arrows) extending superiorly from
transverse colon at site of PEG tube to gastric fundus is opacified, with a
tiny amount of contrast material entering lumen of fundus (short white
arrow), indicating presence of gastrocolic fistula.
