Objective To explore the effect of different nutrition on the immune function of patients with colorectal cancer. Methods A total of 640 colorectal cancer patients were randomized into the enteral nutrition and peripheral nutrition groups. The peripheral venous blood was sampled before operation and on the postoperative days 1 and 7 to determine the serum levels of IgG, IgA, IgM, the percentage of T lymph cell subgroups CD3, CD4, CD4/CD8 and CRP, PGE, α- antitrypsin etc. The patient’s general condition, side-effects, and complications were observed intimately after surgery. Results Compared with the control group, the IgG, IgA, IgM, CD3, CD4,CD4/CD8 levels of the trial group on postoperative day 7 were higher. But the levels of CRP, PGE, α- antitrypsin were decreased. Hospitalization time and anal exsufflation time were shorter as well. There was no significant difference in either the general conditions or complications between the two groups. Conclusion Application of enteral nutrition after colorectal cancer surgery is safe, ,effective, and can improve the patient’s immune function and prognosis.
Objective To compare the differences in evaluating readiness for hospital discharge between nurses and colorectal cancer (CRC) patients following enhanced recovery after surgery (ERAS) pathway. Methods A cross-sectional survey was conducted in Department of Gastrointestinal Surgery, West China Hospital, Sichuan University. Patient-reported Readiness for Hospital Discharge Scale (RHDS) and nurse-reported RHDS were delivered to 130 CRC patients and 40 nurses respectively. All patients were followed ERAS pathway during perioperative periods. The differences were compared in evaluating readiness for hospital discharge between nurses and CRC patients. Results This study investigated 130 CRC patients and 40 responsible nurses. The scores of RHDS from nurses and patients were 162.86±27.95 and 149.86±33.65 respectively. When evaluating whether patients were ready to go home after discharge, the consistency between nurses’ results and patients’ results was weak（κ=0.365, P<0.001）. Items in patients’ RHDS scoring ranking from high to low were expected support, coping ability, knowledge, and personal status. Items in nurses’ RHDS scoring ranking from high to low were expected support, knowledge, coping ability, and personal status. Besides the " social support” dimension, the scores of other 3 dimensions from nurses were significantly higher than those from patients (P<0.05). Conclusion There is a gap between the assessment of RHDS from nurses and patients, nurses overestimated patients’ discharge readiness level.
ObjectiveTo explore the influence of enhanced recovery after surgery (ERAS) on intestinal flora in patients with colorectal cancer.MethodsBy convenient sampling method, 60 patients with colorectal cancer were selected from August 2018 to December 2019 in the Department of Gastrointestinal Surgery of West China Hospital of Sichuan University and randomly divided into ERAS group and traditional treatment group (traditional group). Among them, the perioperative clinical management was carried out according to the ERAS management and traditional treatment process in the the ERAS group and in the traditional group, respectively. The fresh fecal samples were collected within 24 h after admission and the first natural defecation after operation. The bacterial 16 Sr DNA V3–V4 region was sequenced by Illumina MiSeq sequencer, and the results were analyzed by bioinformatics.ResultsA total of 60 patients with colorectal cancer were included, 30 cases in the traditional group and 27 cases in the ERAS group (3 people temporarily withdrew from the study). There were no significant differences in the basic informations between the two groups (P>0.05). ① Before or after operation, there were no significant differences in Shannon index and Simpson index between the two groups. The difference between preoperative and postoperative comparison in the same group was also not statistically significant (P>0.05). ② Beta diversity analysis showed that there was no significant difference in community composition between the traditional group and the ERAS group before operation, and there was a clear boundary between the traditional group and the ERAS group after operation. ③ At the phylum level, compared with the preoperative abundance, the postoperative abundance Firmicutes decreased by 26.5% and 5.5% in the traditional and ERAS group, respectively; Bacteroidetes increased by 21.6% and 4.7% in the traditional and ERAS group, respectively; Proteobacteria increased by 7.2% and 2.2% in the traditional and ERAS group, respectively. At the genus level, compared with the preoperative abundance, the postoperative abundance of Bacteroides in the traditional group increased by 17.6% and in the ERAS group decreased by 1.6%; Bifidobacterium decreased by 1.8% and 1.3% in the traditional group and in the ERAS group, respectively.ConclusionsERAS does not affect species diversity of intestinal flora. Although ERAS has some damage to structure of intestinal flora, it is weaker than traditional process, so it is more conducive to reconstruction and restoration of intestinal microecological environment.
ObjectiveTo explore the correlation between readiness for hospital discharge and short-term quality of life among colorectal cancer (CRC) patients following enhanced recovery after surgery (ERAS) mode.MethodsSurveys of 127 CRC patients following ERAS mode were conducted in the West China Hospital of Sichuan University. The Readiness for Hospital Discharge Scale and EORTC QLQ-C30 Scale were issued at the discharge and 1 month after the operation, respectively.ResultsThe total score of RHDS was 149.43±33.25. The score of global quality of life was 66.80±18.84. Correlation analysis showed that the total score of RHDS was positively correlated with the score of global quality of life (r=0.220, P=0.013), and negatively correlated with the scores of fatigue, nausea and vomiting, pain, loss of appetite (r=–0.304, P=0.001; r=–0.189, P=0.033; r=–0.257, P=0.004; r=–0.254, P=0.004). The score of personal status dimension were positively correlated with the score of global quality of life and emotional function (r=0.213, P=0.016; r=0.197, P=0.027), and negatively correlated with scores of fatigue, pain and insomnia (r=–0.311, P=0.000; r=–0.264, P=0.003; r=–0.257, P=0.004). The score of knowledge dimension was negatively correlated with nausea and vomiting, pain and loss of appetite (r=–0.212, P=0.017; r=–0.182, P=0.040; r=–0.239, P=0.007). The score of coping ability dimension was positively correlated with the score of global quality of life and physical function (r=0.204, P=0.021; r=0.204, P=0.021), while negatively correlated with scores of fatigue, pain, insomnia and loss of appetite (r=–0.349, P=0.000; r=–0.240, P=0.007; r=–0.202, P=0.022; r=–0.201, P=0.024). The score of expected support was positively correlated with the score of global quality of life (r=0.220, P=0.013), and negatively correlated with scores of fatigue and loss of appetite (r=–0.249, P=0.005; r=–0.227, P=0.010).ConclusionsThe short term quality of life among CRC patients following ERAS keeps at upper middle level, and positively correlated with the readiness for hospital discharge. It is suggested that discharge preparation service is of great significance to improve the quality of life of patients.
ObejectiveTo summarize the research progress of risk factors contributing to postoperative pulmonary infection in gastric cancer, so as to provide reference for medical decision-makers and clinical practitioners to effectively control the incidence of postoperative pulmonary infection in gastric cancer, ensure medical safety and improve the quality of life of patients. MethodThe researches at home and abroad on the factors contributing to pulmonary infection after gastric cancer surgery in recent years were reviewed and analyzed. ResultsThere was currently no uniform diagnostic standard for pulmonary infection. The incidence of postoperative pulmonary infection for gastric cancer varied in the different countries and regions. The pathogenic bacteria that caused postoperative pulmonary infection of gastric cancer was mainly gram-negative bacteria, especially Pseudomonas aeruginosa, Escherichia coli, Acinetobacter boulardii, and Klebsiella pneumoniae. The patient’s age, history of smoking, preoperative pulmonary function, preoperative laboratory indicators, preoperative comorbidities, preoperative nutritional status, preoperative weakness, anesthesia, tumor location, surgical modality, duration of surgery, blood transfusion, indwelling gastrointestinal decompression tube, wound pain, and so on were possible factors associated with postoperative pulmonary infection of gastric cancer. ConclusionsThe incidence of postoperative pulmonary infection for gastric cancer is not promising. Based on the recognition of related factors, it is proposed that it is necessary to develop a risk prediction model for postoperative pulmonary infection of gastric cancer to identify high-risk patients. In addition to the conventional intervention strategy, taking the pathogenesis as the breakthrough, finding the key factors that lead to the occurrence of postoperative pulmonary infection of gastric cancer is the fundamental way to reduce its occurrence.
ObjectiveTo understand the current situation and factors affecting tube blockage (non-mechanical) during hyperthermic intraperitoneal chemotherapy (HIPEC). MethodsAccording to the inclusion and exclusion criteria, the patients with malignant tumors who underwent HIPEC in the Department of Gastroenterology of West China Hospital of Sichuan University from May 2019 to May 2021 were retrospectively gathered. The information about the patient and the occurrence of occlusion during HIPEC were obtained by consulting electronic medical records and perfusion records. The logistic regression analysis was performed to analyze the factors influencing non-mechanical tube blockage during HIPEC. ResultsA total of 240 patients with malignant tumors were gathered. During HIPEC, the non-mechanical tube blockage occurred in 88 patients with malignant tumors, with the incidence of 36.7%. The multivariate analysis results by logistic regression showed that the probabilities of non-mechanical tube blockage during HIPEC were higher in the patients with age≥65 years (OR=2.142, P=0.016), diabetes mellitus (OR=2.326, P=0.007), perfusion speed of 300–450 mL/min (OR=2.778, P=0.001), ascites (OR=2.192, P=0.020), and PCI ≥20 points (OR=4.380, P<0.001). ConclusionsPatients with malignant tumors treated with HIPEC are prone to non-mechanical tube blockage. The patients with middle-aged and elderly, diabetes, low perfusion speed, ascites, and high PCI score need to be of great concern, so as to prevent and deal with tube blockage in time.
Objective To explore the related factors of postoperative pulmonary infection (PPI) in patients undergoing laparoscopic colorectal cancer surgery, and analyze the perioperative management strategy of pulmonary infection combined with the concept of enhanced recovery after surgery (ERAS). Methods Total of 687 patients who underwent laparoscopic colorectal cancer surgery in the colorectal cancer professional treatment group of Gastrointestinal Surgery Center of West China Hospital of Sichuan University from January 2017 to May 2019 were retrospectively included. According to the occurrence of PPI, all the included cases were divided into infection group (n=97) and non-infection group (n=590). The related factors and prevention strategies of PPI were analyzed. Results The rate of PPI among patients underwent laparoscopic resection in our study was 14.1% (97/687). Compared with the non-infection group, the proportions of patients with preoperative complications other than cardiopulmonary, receiving preoperative neoadjuvant radiotherapy and/or chemotherapy, preoperative Eastern Cooperative Oncology Group (ECOG) score 1–2, preoperative Nutrition Risk Screening 2002 (NRS2002) score 1–3, tumor located in the left colon and rectum, combined organ resection, operative time >3 h and postoperative TNM stage Ⅱ patients in the infection group were higher (P<0.05). However, the proportions of patients who used intraoperative lung protective ventilation strategy and incision infiltration anesthesia in the infection group were lower than those in the non-infection group (P<0.05). In the infection group, the proportions of patients who received regular sputum excretion, atomization therapy, balloon blowing/breathing training, stomatology nursing after operation and postoperative analgesia were all significantly lower than those of the non-infection group (P<0.05), whereas the proportions of patients receiving antibiotics and intravenous nutrition after operation were significantly higher than those in the non-infection group (P<0.05). Logistic regression analysis showed that low preoperative NRS2002 score, intraoperative protective ventilation strategy, postoperative respiratory training, and postoperative regular sputum excretion were the protective factors of PPI, while preoperative cardiopulmonary complications, preoperative neoadjuvant chemotherapy, tumor located in the left colon and rectum, late TNM staging and postoperative antibiotics were risk factors for pulmonary infection.Conclusions Preoperative cardiopulmonary complications, preoperative neoadjuvant chemotherapy, tumor location in the left colon and rectum, late TNM staging and postoperative antibiotics are risk factors for pulmonary infection in patients with laparoscopic colorectal cancer. Preoperative good nutritional status, intraoperative protective ventilation strategy, postoperative respiratory training and regular sputum excretion may reduce the incidence of PPI to a certain extent.
