Description of intervention(s) / exposure
Patients who are planned to undergo laparoscopy for treatment of a benign gynaecological indication will undergo three surveys. The surveys will occur prior to surgery, a week following surgery and three months following surgery. Each Survey will take approximately ten minutes to complete.

The first survey will include details of the patients demographic, past medical history, and indication for surgery. Then it will aim to define the patients normal bowel function prior to surgery

The second survey will define the patients post operative bowel habit. The distress or bother caused by the bowels. The use of laxative and opiates that may effect a patients bowel habit.

The third survey will review the patients bowel habits again to see if they have returned to normal function after surgery.

Outcomes
Primary outcome [1] 320796 0
Our primary objective is to define the incidence of new onset constipation in patients undergoing elective laparoscopy. This primary outcome defined using the ROME IV definition of constipation

The primary outcome will be determined using a study-specific survey that is performed by the participant one week following surgery.

The incidence of post-operative constipation, based on a modified ROME IV criteria; Defined
as two or more of:
-Passage of first stool after the third post operative days from surgery
- Straining to pass stool
- Lumpy or hard stools (form 1 or 2 on Bristol stool form scale)
- Sensation of anorectal blockage
- Sensation of incomplete emptying
- Use of manual maneuvers to facilitate bowel motion
- Use of laxatives or enemas to facilitate bowel movements

Secondary outcome [4] 373645 0
Time to bowels return to normal pre-op status
This will be estimated by the participant as the time they felt bowels to return to normal (days or weeks). This assessed using a study specific survery at three months post surgery.

Secondary outcome [6] 373647 0
Incidence of pre-operative constipation (functional or opiate induced constipation) as per Rome IV criteria

This will be assessed by a study specific survey using the ROME IV criteria that is completed by the participant prior to them undergoing surgery
Timepoint [6] 373647 0
measured prior to surgery
Secondary outcome [7] 373648 0
Incidence of post-operative constipation that is persistent at three months follow up (as per ROME IV criteria)

This will be assessed by a study specific survey using the ROME IV criteria that is completed by the participant three months after them undergoing surgery
Timepoint [7] 373648 0
measured at three months post operatively

Summary
Brief summary
We aim to investigate the prevalence of constipation in patients undergoing elective laparoscopy for benign gynaecological indications. We also aim to investigate the negative impact that this has as well as factors that may predispose to this

This will be a prospective observation study. The participants will perform three surveys. Prior to surgery to assess baseline bowel function. One week post surgery to assess the immediate effect of surgery on bowel function. Three months after surgery to determine if symptoms are persistent or resolve
