ObjectiveTo investigate the effects of early enteral nutrition containing ω-3 polyunsaturated fatty acids combined with intravenous infusion of alanyl-glutamine on inflammatory response and immune function of postoperative gastric cancer patients.MethodsA total of 110 patients, accepting radical operation for gastric cancer in West China Hospital of Sichuan University during October 2017 to December 2018, were prospectively incorporated in the study and were randomly divided into 2 groups equally. Patients in the control group were enterally fed with a formula containing ω-3 polyunsaturated fatty acids for 6 consecutive days after surgery. Patients in the experimental group accepted the same enteral feeding but combined with intravenous infusion of alanyl-glutamine (20 g/d). Both enteral feeding and intravenous infusion started within 24 hours after surgery. Peripheral venous blood was gathered within 3 days before surgery and on the morning of the first, third, and seventh postoperative days to detect inflammatory, immunological, and nutritional indexes. Complications, length of hospital stay, and hospital cost were also taken notes.ResultsFifty-two patients in the control group and fifty-two patients in the experimental group respectively finished the study. In both groups, 3 patients withdrew from the study for inadequacy of radical operation. Neutrophilic granulocyte percentage, interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) on the third postoperative day, C-reactive protein (CRP), procalcitonin (PCT), IL-6, and TNF-α on the seventh postoperative day, were significantly lower in the experimental group (P<0.05). Immunological indexes including immunoglobulin G (IGG), immunoglobulin A (IGA), percentage of CD3+ T cells, and percentage of CD4+ T cells, nutritional markers including total protein (TP), plasma albumin (ALB), and prealbumin (PAB) were significantly higher in the experimental group on the seventh postoperative day (P<0.05). When the study ended, none significant differences of the rates of both infectious complications (wound infection, intra-abdominal infection, pulmonary infection, urinary system infection, blood system infection, and anastomotic fistula) and noninfectious complications (diarrhea, abdominal distension, and abdominal pain) were observed between the two groups (P>0.05). Time of the first anal discharge, length of hospital stay, and hospitalization cost between the two groups were not significantly different neither (P>0.05).ConclusionEarly enteral nutrition containing ω-3 polyunsaturated fatty acids combined with intravenous infusion of alanyl-glutamine contributes to reduce inflammatory response and improve immune function and nutrition status of patients with gastric cancer after surgery.
Objective To compare the postoperative outcomes of elderly and non-elderly patients undergoing inguinal hernia repair in same-day surgery mode, and explore the utility and safety of same-day surgery mode in inguinal hernia repair. Methods Patients who underwent inguinal hernia repair in Day Surgery Center, West China Hospital of Sichuan University between January 1st 2021 and October 31st 2021 were prospectively included. The patients were divided into elderly group (≥60 years old) and non-elderly group (18-59 years old). The preoperative conditions, postoperative outcomes, discharge readiness and social support of the two groups were analyzed. Results A total of 451 patients were enrolled, including 111 elderly patients and 340 non-elderly patients. The male proportion, prevalence rates of preoperative comorbidities, and bilateral inguinal hernia proportion in the elderly group were significantly higher than those in the non-elderly group (P<0.05), and the body mass index in the elderly group were significantly lower than that in the non-elderly group (P<0.05). There was no significant difference in anesthesia method, analgesic method, bleeding volume, or surgery time between the two groups (P>0.05). The postoperative pain score of the non-elderly group was higher than that in the elderly group (Z=–2.226, P=0.026), but there was no statistically significant difference in the rate of postoperative unplanned analgesia, rate of discharge delay, pain score on the third day after discharge, re-consultation within one month after discharge, complications within one month after discharge, or post-discharge satisfaction (P>0.05). The total score of social support was higher in the elderly group than that in the non-elderly group (31.77±3.04 vs. 29.75±4.78; t=4.182, P<0.001). Conclusion The same-day surgery mode for inguinal hernia repair is feasible and safe in elderly patients and worthy of implementation.
