Brief Summary

Postoperative constipation affects up to a third of women undergoing minimally invasive (MIS) gynecologic surgery and is a major source of anxiety and discomfort. The average time to first bowel movement after gynecologic surgery is about 2 to 4 days and some factors responsible for this include anesthesia inhibitory effect on gastrointestinal motility, opioid pain medication use, chronic nonsteroidal anti-inflammatory drugs (NSAID) use and anatomic manipulation. There are no established regimens to manage postoperative constipation after minimally invasive gynecologic surgery. Two studies evaluating the implementation of postoperative bowel regimen with polyethylene glycol (PEG) and with Senna and Docusate found no significant impact on postoperative bowel function. There have been no studies looking at the effect of preoperative bowel regimens on postoperative bowel function. The purpose of this study is to evaluate postoperative bowel function after minimally invasive hysterectomy in women receiving a preoperative 10-day bowel regimen of PEG daily.

Outcome Measures

Primary Outcomes (2)

  • Patient Assessment of Constipation Symptoms Questionnaire (PAC-SYM) Score

    Constipation will be evaluated both preoperatively and postoperatively using a validated questionnaires (PAC-SYM/PAC-QOL). Patient assessment of constipation symptoms (PAC-SYM) - The Patient Assessment of Constipation-Symptoms (PAC-SYM) questionnaire, developed through psychometric evaluation of adults with chronic constipation, is a tool for assessing the severity of patient-reported symptoms of this disorder. The 12-item questionnaire is divided into three symptom subscales: abdominal (four items); rectal (three items); and stool (five items). Items are scored on 5-point Likert scales, with scores ranging from 0 to 4 (0 = 'symptom absent', 1 = 'mild', 2 = 'moderate', 3 = 'severe' and 4 = 'very severe'). A mean total score in the range of 0-4 is generated by dividing the total score by the number of questions completed; the lower the total score, the lower the symptom burden.

    change in score from 10 days pre-operation to 7 days post-operation

  • Patient Assessment of Constipation Quality of Life Questionnaire (PAC-QOL) Score

    Patient assessment of constipation quality of life (PAC-QOL) - PAC-Qol is a self-reported questionnaire, was used to measure the quality of life of patients.9 The validated PAC-QoL is composed of 28 items grouped into four subscales: physical discomfort, psychosocial discomfort, worries and concerns, and satisfaction. The first three subscales are used to assess the patient dissatisfaction index, with an overall score ranging from 0 to 96 (where lower scores correspond to better quality of life). The satisfaction subscale includes four items with a global score ranging from 0 to 16, so that each patient's self-reported definitive outcome is defined as either poor (0-4), fairly good (5-8), good (9-12), or excellent (13-16).

    change in score from 10 days pre-operation to 7 days post-operation

Limitations and Caveats

Limitations of this study include a greater than expected dropout rate. With an anticipated 20% drop-out rate, we planned to include 80 patients in our statistical analysis. However, only 50-65 patients (depending on the outcome measure) had completed enough of the study materials to be included in the analysis, so our conclusions are under-powered. Furthermore, this was a non-blinded study, which may have contributed to a reporting bias among participants.
