目的 探讨植物性粪石所致小肠 梗阻的MSCT征象特点。方法 回顾性分析 13例经临床手术及病理证实的植物性粪 石致小肠梗阻患者的MSCT影像资料。结 果 全部13例患者中，完全性小肠梗阻9 例，不完全性小肠梗阻4例。所有病例均 在梗阻部位发现植物性粪石，其中十二指 肠梗阻1例占(8%)，空肠梗阻4例占31%， 回肠梗阻8例占61%。1例回肠梗阻，并发 回肠穿孔、急性腹膜炎。植物性粪石直径 2.4cm-4.1cm。结论 植物性粪石致小肠梗 阻具有较为典型的征象特征，MSCT对其术 前诊断和评估有重要的临床价值。

Objective To explore the MSCT characteristics of small bowel obstruction which due to the phytobezoars. Methods The MSCT imaging data of 13 patients of small bowel obstruction confirmed by clinical surgery and pathology were analysis retrospectively. Results In all 13 patients, 9 cases were complete small bowel obstruction and 4 cases were incomplete small bowel obstruction. 1 case of duodenal obstruction (8%), 4 cases of jejunum obstruction accounted for 31%, and 8 cases of ileum obstruction accounted for 61%. 1 case of ileum obstruction, complicated ileum perforation, acute peritonitis. The size of phytobezoars was about 2.4cm to 4.1cm. Conclusion There is typical characteristic of the small bowel obstruction which due to phytobezoars, and MSCT has important clinical value in preoperative diagnosis and evaluation.
