目的探讨食道癌、贲门癌、胃癌及胰腺癌术后患者早期应用肠内营养的效果。方法 120例上消化道癌症术后患者,包括食道癌43例,贲门癌25例,胃癌37例,胰腺癌15例,依据随机数字表法分为观察组和对照组,各60例。对照组患者应用完全静脉营养,观察组患者应用早期肠内营养,对比两组患者的效果。结果观察组患者术后肛门排气时间、肠鸣音恢复时间和住院时间短于对照组(P<0.05)。观察组患者发生恶心呕吐几率为8.3%,2例因不耐受恶心呕吐终止肠内营养。对照组发生恶心呕吐几率为5.0%,无终止静脉营养患者;两组患者的不良反应发生率和不耐受患者例数比较,差异无统计学意义(P>0.05)。结论食道癌、贲门癌、胃癌及胰腺癌患者术后应用早期肠内营养有利于术后肠胃功能恢复、降低患者的医疗负担,且安全可靠,值得临床应用。 Objective To investigate the effect of early enteral nutrition on patients with esophageal cancer, cardiac cancer, gastric cancer and postoperative patients with pancreatic cancer. Methods A total of 120 cases of upper gastrointestinal cancer patients, including 43 cases of esophageal cancer, 25 cases of gastric cardia, 37 cases of gastric cancer and 15 cases of pancreatic cancer were divided into observation group and control group according to random number table method, 60 cases in each group. Control group patients with complete intravenous nutrition, observation group patients with early enteral nutrition, compared two groups of patients. Results The postoperative anal exhaust time, bowel sounds recovery time and hospital stay in observation group were shorter than those in control group (P <0.05). In the observation group, the incidence of nausea and vomiting was 8.3%, and 2 patients stopped enteral nutrition due to intolerance of nausea and vomiting. The incidence of nausea and vomiting in the control group was 5.0%, with no discontinuation of intravenous nutrition. There was no significant difference in the incidence of adverse reactions and the number of intolerant patients between the two groups (P> 0.05). Conclusion The application of early enteral nutrition after esophageal cancer, gastric cardia cancer, gastric cancer and pancreatic cancer patients is conducive to postoperative gastrointestinal function recovery, reduce the medical burden on patients, and safe and reliable, it is worth clinical application.
