PURPOSE: The aim of the study was to review the records of all children who presented with gastric volvulus in the past 10 years. METHODS: The study group consisted of 21 children with an age range from 0.2 months to 4.3 years who were operated for gastric volvulus from 1992 to 2003. RESULTS: Initial symptoms included acute abdominal pain after meals, vomiting, and in 8 cases, acute apnea associated with pallor, cyanosis, and hypotonia. After the first episode, barium studies revealed an organoaxial gastric volvulus in all cases. The surgical procedure was an anterior gastropexy with reinforcement of the esophagogastric angle performed by laparoscopy in 13 cases and by laparotomy in 8 (1 converted laparoscopy). An associated antireflux fundoplication was done in 3 patients. All children received postoperative antireflux medication for at least 1 month. The follow-up ranged from 4 months to 4.8 years. Two children in the laparotomy group required reoperation (Toupet fundoplication) for persistent gastroesophageal reflux disease. All children are currently symptom-free and without treatment. CONCLUSIONS: Gastric volvulus is a clinical and radiological reality, which can be treated by a gastropexy. Initial fundoplication is not mandatory. The laparoscopic gastropexy is a good option and allows a repeat laparoscopic procedure if needed.PMID: 15937830

BACKGROUND: Gastric volvulus is an uncommon condition, which can be difficult to diagnose and treat. This study represents a large series of patients with the condition. METHODS: All patients presenting with gastric volvulus over a 14-year period were reviewed. RESULTS: Some 36 patients (median age 75 years) were identified. Volvulus, usually secondary to a hiatus hernia, presented acutely in 29 patients. The major symptoms were abdominal pain, vomiting and upper gastrointestinal haemorrhage. The most useful investigations were barium contrast studies and upper gastrointestinal endoscopy, which were helpful in 21 of 25 and 11 of 18 patients respectively. Treatment was conservative in five patients, by open surgery in 13 and laparoscopic repair in 18 (three converted to open operation). There were no major complications and no deaths. Median hospital stay was shorter in patients treated by laparoscopic rather than open surgery (6 (range 4-36) versus 14 (7-50) days; P

Abstract:胃軸捻転症は比較的稀な良性疾患であるが,症例によっては手術療法が必要となる.今回われわれは,胃軸捻転症に対して腹腔鏡下胃固定術を行い良好な結果を得たので,文献的考察を加えて報告する.症例は86歳,女性.5年前に肺癌にて左上葉切除の既往があった.他病にて当院整形外科に入院中,嘔吐,上腹部不快感が認められた.腹部単純X線写真で左横隔膜の挙上と二重胃泡が認められ,胃管留置にて症状は消失した.腹部CT,上部消化管造影にて間膜軸性胃軸捻転症と診断された.内視鏡的に整復するもその後再発をきたしたため,腹腔鏡下胃固定術を施行.捻転の先進部と考えられた胃体部前壁と腹壁を2-0バイクリルで3針縫合固定した.術後経過は良好で,再発は認められていない(著者抄録).
3文献のまとめ.胃軸捻転の病型には噴門と幽門を結ぶ線を軸として回転する長軸性捻転(臓器軸性:organoaxial type:図A), 小弯曲・大弯の中心を結ぶ軸を中心として回転する短軸性捻転(間膜軸性:mesenteroaxial type:図B)と,両者が混在した複合性捻転(combined type)に分けられる. 発生病因として解剖学的に異常を伴う続発性のものと,異常を伴わない特発性に分類される.特発性は胃周囲の胃固定間膜(胃横隔膜間膜, 胃脾間膜, 胃肝間膜, 胃結腸間膜など)の脆弱性が要因となる.続発性の誘因として遊走脾, 無脾症候群などの脾臓疾患や食道裂孔ヘルニア, 横隔膜ヘルニア, 横隔膜弛緩症などの横隔膜疾患が挙げられる.
