Gum chewing has been reported to stimulate bowel motility after open surgery, such as cesarean section and other abdominal surgeries. In general, after laparoscopic surgery problems with reduced bowel motility are not as common as after open surgery. In this study the investigators test the hypothesis that gum chewing is enhancing rapid return of bowel motility after gynecologic laparoscopic surgery. Further the investigators study patient satisfaction and potential side effects of postoperative gum chewing.

Condition Intervention
Postoperative Care
Behavioral: gum chewing

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind (Outcomes Assessor)
Official Title: Does Gum Chewing After Gynecologic Laparoscopy Stimulate Earlier Return of Bowel Motility?

Further study details as provided by Klinikum Klagenfurt am Wörthersee:

Primary Outcome Measures:
  • Time to return to active bowel movements [ Time Frame: participants will be followed for the duration of hospital stay ]
    First active bowel movement is defined as time from operation until first passage of flatus. Time until first defecation will also be measured.

Secondary Outcome Measures:
  • patient satisfaction with postoperative gum chewing [ Time Frame: participants will be followed for the duration of the hospital stay ]
    Satisfaction will be measured with a visual analog scale (1 participant would never chew gum postoperatively again - 10 participant would always like to chew gum postoperatively)

  • Number of participants with adverse events [ Time Frame: participants will be followed for the duration of hospital stay ]
    All problems that are linked to postoperative gum chewing will be recorded (e.g. vomiting, aspiration,...)
