  • EFFECTS OF DIFFERENT ANAESTHESIA FOR CHOLECYSTECTOMY ON GASTROINTESTINAL MOTILITY

    This study was designed to determine the effects of different anaesthesia on the postoperative gastrointestinal motility after cholecystectomy. Postoperative gastrointestinal motility were recorded continuously by means of gastrointestinal manometry in 20 patients subject to cholecystectomy (general anaesthesia 10, epidural anaesthesia 10). Normal migrating motor complex (MMC) was abolished during the early postoperative period in all patients. The time of reappearance of intestinal MMC varied from 0.5 to 2 hours . Gastric MMC recurred 5.5 to 14 hours postoperatively and the normal MMC completely recovered 22 to 43 hours after the operations. Ingestion of food changed the MMC into a fed pattern during the early postoperative period. There was no difference between the general anaesthesia group and epidural anaesthesia group in terms of gastrointestinal motility. The results indicate that postoperative gastrointestinal motility recovers faster than that was thought conventionally. Cholecystectomy under general anaesthesia or under epidural anaesthesia makes no difference in postoperative gastrointestinal motility.

  • 胃肠动力剂对术后胸腔胃状态的影响

    目的 了解食管癌根治术后胸腔胃不同部位的压力及pH值的变化,评价比较胃肠动力药物对胃压力波的影响,为术后选择用药提供依据.方法 20例胸中、上段食管癌患者,经右胸作食管癌切除,胃代食管颈部吻合.于术后14~16天随机分为多潘立酮组和西沙必利组,每组10例,于口服相同剂量(20mg)多潘立酮或西沙必利前、后分别描记胸腔胃压力波,测量其频率、峰值和峰值持续时间,比较服药前、后的变化.同时逐段测定胸腔胃基础pH值.结果 两组胸腔胃基础压力值无差异.多潘立酮对胸腔胃的压力峰值有正性作用,但以胃窦区为显著(P<0.01),西沙必利则明显增高胸腔胃各段的压力峰值;胃内自下而上pH值渐次升高,较正常酸度降低.结论 食管癌术后胸腔胃呈一相对高频低幅的压力变化,胃内酸度降低.多潘立酮和西沙必利均有一定增高胸腔胃压力幅度的效果,但以西沙必利效果更好.

  • Experimental Research of Mechanism of Gastrointestinal Motility Disorder of Severe Acute Pancreatitis in Rats

    Objective To investigate the mechanism of gastrointestinal motility disorder of severe acute pancreatitis (SAP) in rats. Methods SD rats were randomly divided into 2 groups:sham operation (SO) group (n=16) and SAP group (n=16). The gastric antrum interdigestive myoelectric complex (IMC) of rat was recorded by using bipolar silver electrode recording, the concentration of serum motilin (MTL) and vasoactive intestinal peptide (VIP) were detected by enzyme-linked immunosorbent assay (ELISA) method, and determined the pancreatic pathology score. Results Compared with SO group, the concentration of serum MTL obvious decreased and the concentration of VIP obvious rised in SAP group (P<0.01). Compared with SO group, the time of IMC cycle, andⅠand Ⅱ phase were extended, and time of Ⅲ phase was shortened, also the amplitude and frequency of peak electric of Ⅲ phase were declined in SAP group (P<0.01). And the concentration of MTL in SAP group showed positive correlation with the time of Ⅲ phase of IMC (r=0.967, P<0.01), the concentration of VIP in SAP group showed negative correlation with the time of Ⅲ phase of IMC (r=-0.592, P<0.05). The pancreatic organization pathological score in SAP group was higher than that in SO group (P<0.01). Conclusion There is gastrointestinal motility disorder in SAP rats, furthermore, it may induce gastrointestinal motility disorder through effecting the gastrointestinal smooth muscle electrical activity.

  • Effect of Laparoscopic Radical Gastrectomy on Gastrointestinal Motility and Gastrointestinal Hormones in Patients with Gastric Cancer

    ObjectiveTo investigate effect of laparoscopic radical gastrectomy on gastrointestinal motility and gastrointestinal hormones in patients with gastric cancer. MethodsTwo hundred and eighty-nine patients who underwent laparoscopic radical gastrectomy from December 2013 to December 2015 were selected as observation group, 325 patients underwent laparotomy radical gastrectomy during the same period were selected as control group. The postoperative bowel sounds recovery time, the first anal exhaust time, and gastrin, motilin and vasoactive intestinal peptide levels in blood at 12 h before operation and at 24 h after operation were compared between these two groups. ResultsThe baselines had no significant differences between these two groups (P > 0.05). The postoperative bowel sounds recovery time and the first anal exhaust time in the observation group were significantly shorter than those in the control group (P < 0.05). Compared with the levels at 12 h before operation, the gastrin and motilin levels were significantly decreased and the vasoactive intestinal peptide level was significantly increased at 24 h after operation in these two groups (P < 0.05); Compared with the control group, the gastrin and motilin levels at 24 h after operation were significantly increased (P < 0.05) and the vasoactive intestinal peptide level was significantly decreased in the observation group (P < 0.05). ConclusionsPostoperative gastrointestinal motility recovery time in patients undergoing laparoscopic radical gastrectomy is significantly faster than that of laparotomy radical gastrectomy. There is a certain relation between gastrin, motilin or vasoactive intestinal peptide change and operation mode, it might be one of mechanisms of faster recovery of gastrointestinal motility after laparoscopic radical gastrectomy for gastric cancer.
