治療的PEG（内視鏡的胃瘻造設術）後，再捻転し手術を要した，Duchenne型筋ジストロフィー症にともなう習慣性胃軸捻転症の1例

A 20-year-old man with Duchenne muscular dystrophy (DMD) with recurrent gastric volvulus underwent percutaneous endoscopic gastrostomy (PEG). Four months later, he developed vomiting and consciousness disturbance. CT revealed gastric volvulus recurrence along the gastrostomy axis. Endoscopic repositioning failed and fistula perforation necessitated emergency surgery. The upper position of the stomach was twisted counter-clockwise and revolved on the gastrostomy axis sliding between the lower stomach and abdominal wall. The fistula showed necrotic perforation and was thus resected. The anterior stomach wall was fixed to the abdominal wall at 3 triangular points. Thereafter, gastric volvulus did not recur. PEG is reportedly effective for preventing gastric volvulus, but there are rare cases of postgastrostomy recurrence. This successfully managed case provides valuable clinical insights.
