Ingestion of fruit pit must be a frequent and innocuous phenomenon, judging from the expected frequency of such occurrences and the relative dearth of medical reports to the contrary. Reported here are four cases in which fruit pits of varied nature completed an otherwise incomplete intestinal obstruction. On of these was in the terminal ileum, with incomplete obstruction due to regional ileitis, in which the offending pit was seen radiologically but was not recognized as such. The other three were in the transverse colon, at the site of annular carcinomatous lesions. The completion of the obstruction by the fruit pits eventuated in earlier symptoms, diagnosis, and treatment. In one case, the fruit pits were multiple; in the remainder, they were single.
从这类事件的预期发生频率以及相反的医学报告相对较少来看，摄入果核想必是一种常见且无害的现象。本文报告了4例不同性质的果核导致原本不完全性肠梗阻完全梗阻的病例。其中1例位于回肠末端，因局限性回肠炎导致不完全梗阻，在影像学上可见致病果核，但当时未被识别出来。另外3例位于横结肠，在环状癌性病变部位。果核导致梗阻完全梗阻，从而使症状、诊断和治疗出现得更早。1例果核为多个；其余病例中果核为单个。
