Less than 2% of gastric neoplasms that are resected surgically are of smooth-muscle origin. Gastric leiomyomas are not encapsulated, and the distinction of benign from malignant leiomyoma may be difficult. Some of these tumors manifest malignant behavior. The histological basis for the diagnosis of benign or malignant smooth-muscle tumor is not entirely satisfactory, and misclassification occurs in some cases. The aggressiveness of those tumors reported as malignant is usually low, and the term "malignant leiomyoma" is usually used rather than the more ominous "leiomyosarcoma." A case is presented of a patient with a 4.5-cm leiomyoma of the gastric antrum resected by the laparoscopic approach. Four laparoscopy trocars were used and multiple applications of the Endo-GIA were needed. Satisfactory margins of resection were obtained. The patient made an excellent recovery with minimal pain. She promptly returned to work and full physical activity.
手术切除的胃肿瘤中，起源于平滑肌的不到2%。胃平滑肌瘤没有包膜，区分良性和平滑肌肉瘤可能很困难。其中一些肿瘤表现出恶性行为。诊断良性或恶性平滑肌肿瘤的组织学依据并不完全令人满意，有些病例会出现误诊。那些被报告为恶性的肿瘤侵袭性通常较低，通常使用“恶性平滑肌瘤”一词，而不是更不祥的“平滑肌肉瘤”。本文介绍了一例通过腹腔镜手术切除胃窦4.5厘米平滑肌瘤的患者。使用了四个腹腔镜套管针，需要多次使用Endo-GIA。获得了满意的切除边缘。患者恢复良好，疼痛轻微。她很快就恢复了工作和完全的体力活动。
