Electrogastrograms (EGGs) were recorded in patients both before and after receiving proximal gastrectomy plus jejunal interposition (PGJI) or just after receiving total gastrectomy plus jejunal interposition (TGJI). Intraluminal pressure was also recorded in some postoperative patients. The EGG 3 cpm component (2.5-4.9 cpm) remained after PGJI, but subsequently decreased with a significant reduction in the preoperative to postoperative ratio of the 3 cpm components (P<0.05). The mean frequency of the 3 cpm components increased significantly after PGJI (P<0.05) and its instability factor increased. The EGG 10 cpm components became relatively dominant compared to other frequency components in 2 out of 8 of patients having PGJI but the mean amplitude of 10 cpm decreased. In TGJI patients, only the 10 cpm component was conspicuous in EGG as in the case of total gastrectomy and Roux en Y anastomosis procedures. The spectral frequencies of intraluminal pressure in the interposed jejunum were similar to the EGG of 10 cpm components both in the case of PGJI and TGJI patients. In conclusion, surface EGG could record the electrical activities of the interposed jejunum more easily in patients having had TGJI than in PGJI.
在接受近端胃切除术加空肠间置术（PGJI）之前和之后以及接受全胃切除术加空肠间置术（TGJI）之后，对患者进行了胃电图（EGG）记录。还对一些术后患者记录了腔内压力。PGJI术后，EGG的3次/分钟成分（2.5 - 4.9次/分钟）依然存在，但随后下降，3次/分钟成分的术前术后比值显著降低（P<0.05）。PGJI术后，3次/分钟成分的平均频率显著增加（P<0.05），其不稳定因素增加。在接受PGJI的8例患者中的2例中，与其他频率成分相比，EGG的10次/分钟成分变得相对占主导地位，但10次/分钟的平均振幅降低。在TGJI患者中，与全胃切除术和Roux-en-Y吻合术的情况一样，EGG中只有10次/分钟成分明显。在PGJI和TGJI患者中，间置空肠的腔内压力频谱频率与EGG的10次/分钟成分相似。总之，与PGJI患者相比，表面EGG在TGJI患者中更容易记录间置空肠的电活动。
