RÉSUMÉ
Objective:To analyze the effect of intestinal fluid reinfusion after anterior resection of rectum and preventive ileostomy in patients with low rectal cancer.Methods:A prospective research method was used, and 60 patients with low rectal cancer in Zhejiang Jinhua Guangfu Tumor Hospital from January 2021 to June 2022 were enrolled. The patients were divided into control group (treated with anterior resection of rectum and preventive ileostomy) and observation group (treated with anterior resection of rectum and preventive ileostomy combined with intestinal fluid infusion) by random number table method with 30 cases each. On the next day and 3 months after surgery, the low anterior resection syndrome (LARS) scale was used to evaluate anal function, the patient-generated subjective global assessment (PG-SGA) method was used to evaluate nutritional status, the stoma-quality of life (stoma-QOL) was used to evaluate the quality of life. The complications were recorded.Results:Both groups of patients were successfully completed the scheduled surgery. There were no statistical differences in LARS score and incidence of LARS on the next day after surgery between the two groups ( P>0.05); the LARS score and incidence of LARS 3 months after surgery in observation group were significantly lower than those in control group: (18.63 ± 3.15) scores vs. (24.90 ± 6.11) scores and 23.33% (7/30) vs. 46.67% (14/30), and there were statistical differences ( P<0.01 or <0.05). There were no statistical differences in PG-SGA score and incidence of malnutrition on the next day after surgery between the two groups ( P>0.05); the PG-SGA score and incidence of malnutrition 3 months after surgery in observation group were significantly lower than those in control group: (3.07 ± 0.82) scores vs. (5.13 ± 1.01) scores and 26.67% (8/30) vs. 46.67% (14/30), and there were statistical differences ( P<0.01 or <0.05). There were no statistical differences in the scores of psychological burden, social interaction, stoma management and daily living of stoma-QOL on the next day after surgery between the two groups ( P>0.05); the scores 3 months after surgery in observation group were significantly higher than those in control group: (27.70 ± 4.28) scores vs. (21.47 ± 5.16) scores, (14.33 ± 2.03) scores vs. (11.90 ± 1.64) scores, (14.87 ± 1.92) scores vs. (11.57 ± 2.38) scores and (15.30 ± 1.03) scores vs. (12.37 ± 2.11) scores, and there were statistical differences ( P<0.01). The incidence of complications in observation group was significantly lower than that in control group: 30.00% (9/30) vs. 60.00% (18/30), and there was statistical difference ( χ2 = 5.45, P<0.05). Conclusions:For the patients with low rectal cancer, the anterior resection of rectum and preventive ileostomy combined with intestinal fluid reinfusion can reduce LARS, improve nutritional status, improve quality of life, and also reduce complications.
