【Abstract】ObjectiveTo generally analyze the current situations of clinical research and applications in early enteral nutrition (EEN) after abdominal surgery. MethodsThe published papers about the current situations of clinical research and applications in EEN after abdominal surgery were reviewed. ResultsEEN after abdominal surgery seems to be safe and effective, produces a positive nitrogen balance, keeps the integrality of structure and function of the apparatus, protects gut barrier, and reduces or prevents septic complications. ConclusionEEN may be of more benefits and will be one of the best methods of nutrition support after abdominal surgery.
Objective To investigate the safety and efficiency of a blood glucose control method in diabetic patients with gastrointestinal neoplasm who were subjected to postoperative early enteral nutrition (EEN). Methods Thirty-seven diabetic patients with gastrointestinal neoplasm received enteral nutriment——Glucerna SR through nasojejunal tubes 24 hours after operation. The blood glucose level was safely controlled through injecting insulin intravenously and subcutaneously. Meanwhile, any change of blood and urine glucose level was monitored and the indexes representing the levels of nutrition, biochemistry and immunity were measured before the implementation of EN, 5 d and 8 d of EN after operation, respectively. Results All the patients were able to bear EEN and there was no severe complications occurred. Significant increase of serum levels of albumin, prealbumin and transferrin were observed after EEN support （P＜0.05）, as well as the serum levels of IgG， IgA and IgM （P＜0.01）. However, body weight， HGB and the serum levels of ALT and TBIL showed no significant changes （Pgt;0.05）. There were 81.1%（30/37） of patients whose blood glucose levels were controlled steadily within the range of (7.8±1.1) mmol/L. Conclusion Injecting insulin intravenously and subcutaneously after operation may be a safe and effective method to control blood glucose level. And the postoperative implementation of EEN can be considered as the first choice of nutrition support for diabetic patients with gastrointestinal neoplasm.
ObjectiveTo systematically review the predictors of enteral nutrition feeding intolerance in critically ill patients. MethodsThe PubMed, Web of Science, Cochrane Library, Embase, CNKI, WanFang Data, VIP and CBM databases were searched to collect relevant observational studies from the inception to 6 August, 2022. Two reviewers independently screened the literature, extracted data, and assessed the risk of bias of the included studies. Meta-analysis was then performed using RevMan 5.4 software. ResultsA total of 18 studies were included, including 28 847 patients. The results of the meta-analysis showed that gender, age, severity of illness, hypo-albuminemia, length of stay, postpyloric feeding, mechanical ventilation and mechanical ventilation time, use of prokinetics, use of sedation drugs, use of vasoactive drugs and use of antibiotics were predictors of enteral nutrition feeding intolerance in critically ill patients, among which postpyloric feeding (OR=0.46, 95%CI 0.29 to 0.71, P<0.01) was a protective factor. ConclusionAccording to the influencing factors, the medical staff can formulate a targeted enteral nutrition program at the time of admission to the ICU to reduce the occurrence of feeding intolerance. Due to the limited quantity and quality of the included studies, more high-quality studies are needed to verify the above conclusion.
Objective To evaluate the clinical curative effect of early enteral nutrition （EN） in gastric cancer patients after operation and its safety. Methods One hundred and eighty patients with gastric cancer diagnosed and underwent surgical treatment in gastrointestinal surgery center， West China Hospital from February 2011 to December 2011 were studied prospectively， who were randomly divided into EN group （n=91） and parenteral nutrition （PN） group （n=89）. The nutrition state， rehabilitation， hospital stay， cost of nutrition in hospital， and complications were observed. Results ①According to the postoperative serum nutrition index， there were no significant differences in the prealbumin， hemoglobin， and ratio of albumin to globulin in two groups （P＞0.05）， but the albumin level in the EN group was significantlyhigher than that in the PN group （P=0.047）. ②According to the postoperative rehabilitation index， the first ambulation time （P=0.011）， first intake time （P=0.000）， first nasogastric tube away time （P=0.013）， first drainage tube away time （P=0.021）， and first urinary catheter away time （P=0.002） in the EN group were significantly shorter than those in the PN group. The difference of the first anus exhaust time was not statistically significant in two groups （P=0.083）. ③The cost of nutrition in hospital in the EN group was significantly less than that in the PN group （P=0.017）. The postoperative hospital stay and total complication rate were not significant differences in two groups （P＞0.05）. Conclusion Early postoperative EN is effective， economic， practical， which might be superior to PN.
ObjectiveTo compare the impact of early enteral nutrition (EN) and parenteral nutrition (PN) on the postoperative efficacy of esophageal cancer through meta-analysis of relevant randomized controlled trial (RCT).MethodsPubMed, Medline, EMbase, The Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang Database, VIP, China Biology Medicine disc (CBMdisc) were searched by computer from inception to April 2018 to identify potential RCT which assessed clinical efficacy between EN and PN for postoperative patients with esophageal cancer. According to the inclusion and exclusion criteria, two researchers independently screened and evaluated literature. Meta-analysis was performed by RevMan 5.3 software.ResultsA total of 30 RCT studies were selected, including 3 969 patients. Meta-analysis results showed that: there was a significant difference between EN and PN in postoperative anastomotic fistulas (I2=0%, OR=0.67, 95%CI 0.45-0.99, P=0.04), postoperative pulmonary infections (I2=0%, OR=0.42, 95%CI 0.32-0.55, P<0.000 1), postoperative albumin levels (I2=38%, MD=0.78, 95%CI 0.51-1.06, P<0.000 01),time of first anal exhaust after operation (I2=0%, MD=–23.16, 95%CI –25.16-21.16, P<0.000 01) and postoperative incision infection (I2=0%, RR=0.36, 95%CI 0.21-0.64, P=0.000 5).ConclusionCompared with PN, early EN can significantly reduce the incidence of major postoperative complications and shorten the time of first anal exhaust after surgery. In addition, EN is superior to PN in improving nutritional status, increasing weight and reducing costs and side effects.
ObjectiveTo investigate the effect of enhanced recovery after surgery (ERAS) combined with preoperative oral nutrition supplement (EnsourceTM) in patients with rectal cancer and its effect on postoperative stress response.MethodsFrom January 2018 to August 2018, 80 patients with laparoscopic assisted radical resection of rectal cancer in our hospital were divided into two groups according to different perioperative management. Forty patients who had used enhanced recovery after surgery combine preoperative application of tumor total nutrition formula enteral nutrition solution were as observation group, while other 40 patients who only had used enhanced recovery after surgery in perioperative as control group. We observed the stress response (mean systolic blood pressure, mean diastolic blood pressure, mean heart rate, mean blood oxygen saturation, pain score and fasting blood glucose) at 24 hours after surgery and the time of the first anal exhaust, complication rate, hospitalization time, and hospitalization cost after surgery in both groups. We also compared the early postoperative (on the second day after operation) nutritional status of the two groups like the levels of serum total protein, albumin and proalbumin.ResultsThe mean systolic blood pressure, mean diastolic blood pressure, mean heart rate, mean blood oxygen saturation, pain score and fasting blood glucose of the observation group at 24 hours after surgery were significantly lower than those of the control group (P<0.05), while the total serum protein, albumin and prealbumin concentrations of the observation group were significantly higher than those of the control group on the second day after surgery (P<0.05). Postoperative hospitalization time and hospitalization cost in the observation group were also shorter or less than those in the control group (P<0.05). Compared with the control group, the first postoperative anal exhaust time was earlier and the incidence of postoperative complications was reduced in the observation group, but the difference was not statistically significant (P>0.05).ConclusionsERAS combined with preoperative application of tumor total nutrition formula enteral nutrition fluid (EnsourceTM) can reduce the postoperative stress response and the postoperative complication rate of patients with rectal cancer, and also improve the postoperative nutrition status of patients and promote the rapid recovery of patients after sugery.

Methods Sixty-six postoperative patients with gastric cancer combined diabetes were divided into 3 groups according to the balanced principle. In the frist group (FD group), FD was the nutrition preparation for 21 patients. In the second group (fresubin group), fresubin and the ordinary insulin injection were the nutrition preparation for 21 patients. In the third group (TPN group), the nutrition preparation came from TPN and the ordinary insulin injection for 24 patients. FD, fresubin or TPN were given at 24 h after operation, the levels of blood glucose for empty stomach, after meal (enteral nutrition or TPN) and the common complications compared among 3 groups of postoperative patients. Results ① In FD group, the levels of blood glucose of postoperative empty stomach and after enteral nutrition were stable with little fluctuation and no insulin was needed with 1 case of hyperglycemia (4.8%). In fresubin group and TPN group, the levels of blood glucose of postoperative empty stomach and after enteral nutrition or TPN were unstable with big fluctuation, with 6 cases (28.6%) and 8 cases (33.3%) of hyperglycemia, 5 cases (23.8%) and 6 cases (25.0%) of hypoglycemia in fresubin group and TPN group, respectively. Compared with fresubin group and TPN group, the rate of pathoglycemia was lower in FD group, the difference had statistical significance separately (Plt;0.05); There was no significant difference between fresubin group and TPN group (Pgt;0.05). ② The rates of infection of incisional wound in FD group (4.8%) and fresubin group (23.8%) were lower than that of TPN group (33.3%), there was significant difference among 3 groups (Plt;0.05); The time of passage of gas by anus in FD group and fresubin group were shorter than that in TPN group (Plt;0.05); There was no significant difference between FD group and fresubin group (Pgt;0.05). There were no significant differences of the rates of abdominal distension or diarrhea among 3 groups (Pgt;0.05). Conclusion Regarding postoperative patients with gastric cancer combined diabetes, in the early time field test group of the nutrition preparation, FD is better than fresubin or TPN, which does not increase the risk of the blood glucose change and have few complications.
