A Cross-Sectional Review of Reporting Variation in Postoperative Bowel Dysfunction After Rectal Cancer Surgery

BACKGROUND: Postoperative bowel dysfunction affects quality of life after sphincter-preserving rectal cancer surgery, but the extent of the problem is not clearly defined because of inconsistent outcome measures used to characterize the condition. OBJECTIVE: The purpose of this study was to assess variation in the reporting of postoperative bowel dysfunction and to make recommendations for standardization in future studies. If possible, a quantitative synthesis of bowel dysfunction symptoms was planned. DATA SOURCES: MEDLINE and EMBASE databases, as well as the Cochrane Library, were queried systematically between 2004 and 2015. STUDY SELECTION: The studies selected reported at least 1 component of bowel dysfunction after resection of rectal cancer. MAIN OUTCOME MEASURES: The main outcome measures were reporting, measurement, and definition of postoperative bowel dysfunction. RESULTS: Of 5428 studies identified, 234 met inclusion criteria. Widely reported components of bowel dysfunction were incontinence to stool (227/234 (97.0%)), frequency (168/234 (71.8%)), and incontinence to flatus (158/234 (67.5%)). Urgency and stool clustering were reported less commonly, with rates of 106 (45.3%) of 234 and 61 (26.1%) of 234. Bowel dysfunction measured as a primary outcome was associated with better reporting (OR = 3.49 (95% CI, 1.99–6.23); p
