The Impact of Preoperative Bowel Exercise on Postoperative Bowel Functions in Gynecologic Malignancies

This randomized study was approved by the Tepecik Training and Research Hospital Ethics Committee and conducted between January 1, 2023, and August 31, 2023. Patients diagnosed with gynecologic malignancies at our center were included in the study. Patients in the study group were provided with abdominal exercises one week before surgery, and they practiced exercises that included abdominal massage and rectal digital stimulation during the week leading up to the operation. Patients who did not perform exercises were included as the control group.

Participants were randomized after obtaining written informed consent forms. Patients with an operation plan were assigned to one of the two groups through randomization by the principal investigator. Group 1 patients constituted the control group, while Group 2 consisted of patients who regularly performed the recommended bowel exercise program every morning one week before the surgery. The recommended bowel exercise program was explained in detail to patients by the responsible researcher on the day of their preoperative anesthesia preparations (at least 10 days before the surgery) in the pre-op preparation room, accompanied by visual presentations. The recommended bowel exercise program consisted of three steps:

• Patients will perform a 2-3 minute massage starting from the cecum approximately 20-30 minutes after breakfast, moving along the colon.
• Patients will assume a suitable position and perform circular massage on the anal walls with their finger for approximately 30 seconds (digital rectal stimulation).
• Patients will try to defecate while sitting on the toilet.

Inclusion criteria

• Patients who underwent surgery for endometrium, cervical and ovarian cancer indications,
• Patients with American Society of Anesthesiologists (ASA) score 1 or 2

Exclusion criteria

• Those with inflammatory bowel disease,

• Patients with a history of abdominal bowel surgery,
• Those who received abdominal radiotherapy, hyperthermic intraperitoneal chemotherapy or neoadjuvant chemotherapy,
• Patients who had bowel injuries during surgery, bowel resection, anastomosis or colostomy,
• Patients who underwent Hipec,
• Patients who underwent relaparotomy before discharge due to reasons such as bleeding or evisceration
