Colectomy for chronic constipation (CC) may offer benefits but carries significant risks. Evidence is insufficient to guide patient selection or procedural choices for this surgery.
Area of Science:
- Gastroenterology
- Surgical Outcomes
- Evidence-Based Medicine
Background:
- Chronic constipation (CC) significantly impacts quality of life.
- Surgical interventions like colectomy are considered for refractory CC.
- Outcomes and risks associated with colectomy for CC require thorough evaluation.
Purpose of the Study:
- To systematically assess the outcomes of colectomy in adult patients diagnosed with chronic constipation.
- To synthesize evidence regarding the benefits and harms of colectomy for CC.
- To evaluate the current evidence base for guiding clinical decisions in colectomy for CC.
Main Methods:
- Systematic review adhering to PRISMA 2016 guidelines.
- Inclusion of 40 articles reporting outcomes in 2045 patients.
- Evidence synthesis using Summary Evidence Statements (SES) with Oxford Centre for Evidence-Based Medicine (2009) levels.
Main Results:
- Colectomy, primarily colectomy and ileorectal anastomosis (CIRA), shows variable outcomes.
- Complications occurred in ~24% of patients, with 0.4% procedure-related deaths.
- Long-term risks include ~15% recurrent small bowel obstruction, necessitating re-hospitalization and further surgery.
Conclusions:
- Colectomy for CC can provide benefits but is associated with considerable short- and long-term morbidity.
- Current evidence is inadequate to inform patient selection or specific procedural choices.
- Further research is needed to clarify optimal surgical strategies and patient selection criteria for CC.
