This study attempts to characterize any changes occurring in the human gastric control electrical rhythm (CER), following a variety of gastric surgical procedures. Pairs of electrodes were implanted in selected specific sites on the stomachs of 57 patients undergoing either antrectomy and vagotomy, proximal gastric vagotomy (PGV), vagotomy and drainage, gastric resection without vagotomy, or fundoplication. Five patients undergoing nongastric operations served as controls. After operation recordings were obtained with differential preamplifiers, an oscilloscope, and a dual-channel tape recorder. An electrical signal compatible with a CER was found almost always in the distal body or antrum, regardless of whether vagotomy was performed. In contrast, a CER was found only occasionally in the fundus, and was never found following PGV. Although there was a difference in the frequency of occurrence of fundic CER in patients with and without vagotomy, it was not statistically significant (p = 0.0668). Patients with prolonged postoperative convalescence because of gastric atony were compared with patients with normal postoperative courses regarding the presence or absence of CER in the gastric antrum or fundus. A statistically significant relationship between abnormal gastric motility and absence of CER was not established.
本研究试图描述在进行各种胃部手术后，人体胃控制电节律（CER）发生的任何变化。在57例接受胃窦切除术和迷走神经切断术、近端胃迷走神经切断术（PGV）、迷走神经切断术和引流术、非迷走神经切断术的胃切除术或胃底折叠术的患者的胃的选定特定部位植入成对电极。5例接受非胃部手术的患者作为对照。术后用差分前置放大器、示波器和双通道磁带录音机进行记录。几乎在所有病例中，无论是否进行了迷走神经切断术，在胃体远端或胃窦部均发现了与CER相符的电信号。相比之下，仅偶尔在胃底发现CER，而在PGV术后从未发现。虽然迷走神经切断术患者和未行迷走神经切断术患者胃底CER的出现频率存在差异，但无统计学意义（p = 0.0668）。将因胃无力导致术后恢复时间延长的患者与术后恢复正常的患者在胃窦或胃底CER的有无方面进行比较。未确立胃动力异常与CER缺失之间的统计学显著关系。
