The roentgenographic finding hepatic--portal venous gas (HPVG) has been reported extensively in the pediatric and radiology literature. The surgical implications and clinical significance have yet to be fully defined. This study reviews the 60 reported cases in the literature and adds four new cases. HPVG appears as a branching radiolucency extending to within 2 cm of the liver capsule. HPVG is associated with necrotic bowel (72%), ulcerative colitis (8%), intra abdominal abscess (6%), small bowel obstruction (3%), and gastric ulcer (3%). Mucosal damage, bowel distention and sepsis predispose to HPVG. The current mortality rate of 75% represents an improvement from previous experience. Analysis of survivors indicates that the finding of HPVG requires urgent surgical exploration except when it is observed in patients with stable ulcerative colitis.
肝门静脉积气（HPVG）的X线表现已在儿科和放射学文献中被广泛报道。其手术意义和临床重要性尚未完全明确。本研究回顾了文献中报道的60例病例，并新增了4例。HPVG表现为延伸至肝包膜内2厘米范围内的分支状透亮区。HPVG与坏死性肠病（72%）、溃疡性结肠炎（8%）、腹腔内脓肿（6%）、小肠梗阻（3%）和胃溃疡（3%）相关。黏膜损伤、肠扩张和脓毒症易引发HPVG。目前75%的死亡率较以往有所改善。对幸存者的分析表明，发现HPVG需要紧急进行手术探查，除非在溃疡性结肠炎稳定的患者中观察到该情况。
