Between 1979 and 1982, 162 patients underwent horizontal gastroplasty in which polypropylene mesh (Marlex) was used to support the greater curve channel. There were no deaths and early weight loss was good. The operation was stopped because of late weight gain. Marlex erosion was recognized by endoscopy in 10 (6%) patients between 27 and 60 months after operation. Two other patients with Marlex erosion had the gastroplasty performed elsewhere. The patients' symptoms were abdominal pain, vomiting or weight gain. The Marlex was often difficult to resect because the inflammatory mass was adherent to spleen or pancreas. Reconstruction by Roux-en-Y gastric bypass or vertical banded gastroplasty allowed continued weight loss and gastrogastrostomy, although technically easier, resulted in weight gain. The author concludes that long-term follow-up is necessary after any gastroplasty or gastric bypass procedure especially when foreign material is used to support the stoma.
1979年至1982年间，162例患者接受了水平胃成形术，术中使用聚丙烯网（Marlex）支撑胃大弯通道。无死亡病例，早期体重减轻情况良好。该手术因后期体重增加而停止。术后27至60个月，10例（6%）患者经内镜检查发现Marlex网侵蚀。另外两名发生Marlex网侵蚀的患者在其他地方接受了胃成形术。患者的症状为腹痛、呕吐或体重增加。Marlex网通常难以切除，因为炎性肿块与脾脏或胰腺粘连。采用Roux-en-Y胃旁路术或垂直束带胃成形术进行重建可使体重持续减轻，而胃胃吻合术虽然技术上更简单，但会导致体重增加。作者得出结论，任何胃成形术或胃旁路手术后都需要进行长期随访，尤其是在使用异物支撑造口时。
