研究背景：择期乙状结肠切除术患者术后嚼口香糖可激发肠动力、减少术后肠道功能恢复时间。
实验设计：这项前瞻随机性性研究在一家社区教学医院进行。
病人：该研究纳入34例复发性乙状结肠憩室炎或结肠癌行择期乙状结肠切除术的患者。
评价指标：首次出现饥饿感时间、首次排气时间、首次排便时间、住院时间及并发症情况。
结果：病人随机分配至口香糖组(n=17)与对照组(n=17)。口香糖组患者每日嚼无糖口香糖3次,每次1小时,直至出院。口香糖组患者首次排气时间为术后65.4小时,对照组为80.2小时(P=0.05)。口香糖组患者首次排便时间为术后63.2小时,对照组为89.4小时(P=0.04)。口香糖组患者首次饥饿感时间为术后63.5小时,对照组为72.8小时(P=0.27)。两组患者均未发生重大并发症。口香糖组患者住院时间较对照组短(分别为4.3天与6.8天,P=0.01)。
结论：嚼口香糖可通过激发肠动力,促进择期乙状结肠切除术患者术后康复。嚼口香糖是一种结肠切除术后经济且有效的辅助护理措施。

HYPOTHESIS: Gum chewing after elective open colon resection may stimulate bowel motility and decrease duration of postoperative ileus. DESIGN AND SETTING: Prospective, randomized study in a community-based teaching hospital. PATIENTS: Thirty-four patients undergoing elective open sigmoid resections for recurrent diverticulitis or cancer. MAIN OUTCOME MEASURES: First feelings of hunger, time to first flatus, time to first bowel movement, length of hospital stay, and complications. RESULTS: A total of 34 patients were randomized into 2 groups: a gum-chewing group (n = 17) or a control group (n = 17). The patients in the gum-chewing group chewed sugarless gum 3 times daily for 1 hour each time until discharge. Patient demographics, intraoperative, and postoperative care were equivalent between the 2 groups. All gum-chewing patients tolerated the gum. The first passage of flatus occurred on postoperative hour 65.4 in the gum-chewing group and on hour 80.2 in the control group (P = .05). The first bowel movement occurred on postoperative hour 63.2 in the gum-chewing group and on hour 89.4 in the control group (P = .04). The first feelings of hunger were felt on postoperative hour 63.5 in the gum-chewing group and on hour 72.8 in the control group (P = .27). There were no major complications in either group. The total length of hospital stay was shorter in the gum-chewing group (day 4.3) than in the control group (day 6.8), (P = .01). CONCLUSIONS: Gum chewing speeds recovery after elective open sigmoid resection by stimulating bowel motility. Gum chewing is an inexpensive and helpful adjunct to postoperative care after colectomy.
