Objective: This study aims to examine the mechanism through which the dietary fiber-based enteral nutrition support program affects intestinal function recovery in patients undergoing different gynecological abdominal surgery. 

Methods: A total of 208 patients undergoing gynecological abdominal surgery from March 16, 2019 to March 15, 2020 were enrolled in this study and divided into four groups. Accordingly, the groups included group A (open surgery + dietary fiber-based enteral nutrition support, n=52), group B (open surgery + routine diet, n=52), group C (laparoscopic surgery + dietary fiber-based enteral nutrition support, n=52), and group D (laparoscopic surgery + routine diet, n=52). After admission, a fixed dietitian conducted an assessment. After the surgery, trained professional nurses were responsible for observing the main symptoms and signs reflecting postoperative intestinal function recovery, such as abdominal pain, abdominal distension, nausea, and vomiting. Postoperative exhaust time, first defecation time after the surgery, and postoperative hospital stay were recorded. 

Results: There were no differences in general statistics of age, BMI, ratio of menopausal status, diabetes ratio, and surgical classification ratio among the four groups (P>0.05).Comparisons between group A and group B, and between group C and group D showed no statistical differences in the surgery time and intraoperative blood loss (P>0.05); however, decreased bowel sound recovery, exhaust time, defecation time, hospital stay, hospitalization expenses, incidence of abdominal distension, and incidence of intestinal obstruction were observed (P>0.05). Compared to group A and group B, group C and group D experienced a decrease in surgery time, intraoperative blood loss, bowel sound recovery, exhaust time, defecation time, hospital stay, hospitalization expenses, incidence of abdominal distension, and incidence of intestinal obstruction (P<0.05). Comparisons between group A and group B, and between group C and group D showed that the effective rate and total effective rate increased, inefficiency decreased, the relative satisfaction rate and total satisfaction increased, yet dissatisfaction decreased (P>0.05). Besides, comparisons between group C and group A, and between group D and group B showed that the effective rate and total effective rate increased, inefficiency decreased, the relative satisfaction rate and total satisfaction increased, yet dissatisfaction decreased (P<0.05). 

Conclusion: Application of dietary fiber-based enteral nutrition support in patients undergoing gynecological abdominal surgery can promote intestinal function recovery, protect intestinal mucosa barrier function, and prevent postoperative infectious complications.
