Myoelectrical small bowel activity was measured intraoperatively with two serosal electrodes in two groups of patients. 16 patients operated electively for other indications than bowel ischaemia and 10 with small bowel ileus with symptoms of ischaemia. In later cases necrotic bowel was resected. Resected ischaemic bowel was submitted to histological examination and changes in intramural neurones were assessed. Areas of mild, moderate and severe ischaemia were compared to unchanged bowel. Both amplitude and frequency of slow waves in ischaemic bowel was markedly diminished corresponding well with changes in bowel histology. Intraoperative measurements of intestine myoelectrical activity might help a surgeon to estimate a bowel viability.
在两组患者中，术中使用两个浆膜电极测量肌电小肠活动。16例因非肠缺血的其他指征而接受择期手术的患者，以及10例有缺血症状的小肠肠梗阻患者。在后面这些病例中，切除了坏死肠段。将切除的缺血肠段进行组织学检查，并评估壁内神经元的变化。将轻度、中度和重度缺血区域与未改变的肠段进行比较。缺血肠段慢波的幅度和频率均明显降低，与肠道组织学变化非常吻合。术中测量肠道肌电活动可能有助于外科医生评估肠段的活力。
