Objective To explore the status of nutrition risk and its relative factors in patients of department of gastrointestinal surgery, and to observe the effectiveness of nutrition support on post-operative recovery of patients with gastric cancer. Methods A total of 1 048 cases of in-patients in Department of Gastrointestinal Surgery of Jinan Central Hospital Affiliated Shandong University from January 2015 to January 2016 were collected prospectively, and then screened the nutrition risk of these patients by nutritional risk screening 2002 (NRS-2002) and evaluated the actual malnutrition situation when they left hospital. Then collected 52 gastric cancer patients whose NRS-2002 score ≥3, and divided them to control group and experimental group randomly. The patients of experimental group received extra standard medical nutrition support while the patients of control group did not. Compared the nutritional indexes as well as some postoperative recovery indexes, such as the postoperative exhaust time, postoperative defecation time, infusion stop time, length of hospital stay, and incidence of complications. Results ① Nutritional risk. Among the 1 048 cases, 230 cases (21.9%) had nutritional risk while 118 cases (11.3%) developed to malnutrition. Age and degree of cancer were all related with nutritional risk (P<0.05) while gender was irrelevant (P>0.05). Patients with age ≥60 years, advanced gastric cancer, and colorectal cancer in Ⅲ+Ⅳ staging, had higher rates of nutritional risk than patients with age <60 years, early gastric cancer, and colorectal cancer inⅠ+Ⅱstaging. Results of actual malnutrition was in good accordance with the screening result of NRS-2002 (κ=0.57). ② Influence of nutritional support on gastric cancer patients. Compared with control group, there was an improvement in albumin, pre-albumin, and weight of experimental group and the distinction had statistical significance (P<0.05). The distinction of postoperative exhaust time and incidence of complication between the two groups were not statistically significant (P>0.05), but postoperative defecation time, infusion stop time, and the length of hospital stay of the experimental group were shorter than those of the control group with statistical significance (P<0.05). Conclusions The problem of malnutrition exists generally in the in-patients of department of gastrointestinal surgery. Applying the instrument of nutritional risk assessment to assess the risk as early as possible and giving appropriate nutrition support therapy positively, will make favorable influence to the prognosis of gastric cancer patients.
Objective To summarize the nutritional management strategies of patients undergoing electively gastrointestinal surgery. Methods This article reviewed the recent researches on perioperative nutritional management in electively gastrointestinal surgery, including four major directions: preoperative nutritional evaluation, glucose level control, nutritional type, and immunonutrition. Results At present, preoperative nutritional evaluation methods included anthropometry, laboratory tests, subjective global assessment (SGA), nutritional risk screening (NRS) 2002, Reilly nutritional risk screening, nutritional risk indicator (NRI), and so on. For preoperative nutritional assessment system, however, current data could not single out superiority for any nutritional assessment methods in the ability to predict surgery-related complications. The usage of enhanced recovery after surgery (ERAS) protocol to reduce surgical stress and preclude postoperative insulin resistance had recently been clearly linked to reductions in postoperative morbidity and adverse outcomes. There were specific criterias for perioperative parenteral and enteral nutrition in undernourished patients, who were defined in clinical guidelines recently, such as the Guidelines for Adult Perioperative Nutrition Support issued by Chinese Society of Parenteral and Enteral Nutrition (CSPEN). Several systematic reviews showed that immunonutrition could reduce both morbidity and length of stay after major electively gastrointestinal surgery. Conclusion Perioperative nutritional management can ensure patients benefit from nutritional support by nutritional assessment, can reduce the nutritional risk and metabolic disorder caused by operation, can achieve the goal of optimal nutrition support in surgical patients, and can ultimately reduce postoperative complications.
ObjectiveTo explore gut microbiome influences on anastomotic healing following gastrointestinal surgery and its mechanism.MethodThe relevant literatures about gut microbiome and its impact on healing of gastrointestinal anastomosis and their mechanisms were reviewed.ResultsSeveral symbiotic intestinal microbiota such as the Enterococcus faecalis, Pseudomonas aeruginosa, Serratia marcescens, etc. could transform into the pathogenic bacteria with high toxic phenotype in an inflammatory environment in the body, and dissolve the extracellular matrix by degrading collagen or activating matrix metalloproteinase 9, resulting in the anastomotic leak.ConclusionIn general, exploring of effect of intestinal microbiome on healing process of anastomotic stoma is just beginning, conditions and mechanisms for transformation of bacteria from symbiotic to pathogenic still need to be explored.
ObjectiveTo analyze the relationship between preoperative pulmonary function indexes and postoperative pneumonia (POP) in patients undergoing upper gastrointestinal surgery.MethodsThe clinical data of 303 patients who underwent lung function examination and upper gastrointestinal surgery in West China Hospital, Sichuan University from September 2020 to January 2021 were prospectively collected and analyzed. There were 217 males and 86 females, with an average age of 61.61±10.42 years. Pulmonary function was evaluated from four aspects including ventilatory function, pulmonary volume, diffusion function and airway resistance. Relevant pulmonary function indicators were displayed as the percentage of actual measured value to predicted value (%pred). The outcome index was pneumonia within 30 days after the surgery. Logistic regression was used to analyze the relationship between preoperative pulmonary function indicators and POP.ResultsA total of 196 patients with gastric cancer and 107 patients with esophageal cancer were included, and the incidence of POP in patients undergoing upper gastrointestinal surgery was 26.7% (81/303). Patients with preoperative low peak expiratory flow (PEF%pred) had a 3.094 times higher risk of developing POP than those with normal PEF%pred [OR=3.094, 95%CI (1.362, 7.032), P=0.007]. The incidence of POP had no correlation with the other preoperative indicators.ConclusionPreoperative PEF%pred may be an important indicator for predicting the occurrence of POP in patients undergoing upper gastrointestinal surgery.
