The present study was undertaken to determine the frequency with which undigested meat fibres in the stool could be found after partial gastrectomy. A sample of stool was examined in 61 patients who had undergone a partial gastrectomy and in 92 control patients. The age ranges and average ages of both groups were similar. The stools of 77 of the 92 control patients contained well-digested meat fibres, 14 showed partially digested fibres, and one patient had completely undigested meat fibres. In the postgastrectomy group, 44 of 61 patients had well-digested meat fibres and 17 showed partially digested fibres in their stools. None showed undigested fibres. The present study demonstrated that the finding of undigested meat fibres is as infrequent in postgastrectomy patients as in control patients. If undigested meat fibres are found in the stools of postgastrectomy patients, it is suggestive of pancreatic exocrine insufficiency.
本研究旨在确定部分胃切除术后粪便中未消化肉纤维的出现频率。对61例接受部分胃切除术的患者和92例对照患者的粪便样本进行了检查。两组的年龄范围和平均年龄相似。92例对照患者中，77例的粪便含有消化良好的肉纤维，14例显示部分消化的纤维，1例患者有完全未消化的肉纤维。在胃切除术后组中，61例患者中有44例粪便中有消化良好的肉纤维，17例显示部分消化的纤维。没有发现未消化的纤维。本研究表明，胃切除术后患者中未消化肉纤维的发现与对照患者一样罕见。如果在胃切除术后患者的粪便中发现未消化的肉纤维，则提示胰腺外分泌功能不全。
