A 15‐year‐old Thoroughbred gelding showjumper presented with colic after a history of chronic mild, intermittent colic. He was refractory to medical management. At surgery, he was found to have a 15‐cm intramural mass in the distal jejunum, approximately 3 m orad to the ileum. Histopathology post‐operatively revealed a leiomyoma. Leiomyomas in horses are rare. They have been reported most commonly in the reproductive tract, with other rare reports in the oesophagus and omentum. To the knowledge of the authors, there are no reports of identification and treatment of non‐strangulating obstruction of the jejunum caused by a leiomyoma. The horse recovered from his surgery and went on to compete at the same level of showjumping as previous to the surgery with no further episodes of colic. Based on this report, leiomyoma should be a differential for small intestinal obstruction in the future.

空肠空肠平滑肌瘤是绞痛的原因

患有轻度间歇性绞痛的病史，有一名15岁的纯种gel胶跳高者出现绞痛。他不愿接受医疗管理。在手术中，发现他在空肠远端有15 cm的壁内包块，距回肠约3 m。术后组织病理学显示平滑肌瘤。马中的平滑肌瘤很少见。在生殖道中最常见的报道是它们，在食道和大网膜中也有其他罕见的报道。据作者所知，尚无关于识别和治疗由平滑肌瘤引起的空肠非狭窄阻塞的报道。这匹马从手术中恢复过来，继续参加与手术前相同水平的跳跃比赛，没有发生进一步的绞痛发作。根据此报告，
