From Recognition to Prevention: Modern Approaches to Complication Reduction in Colorectal Surgery

Area of Science:

• Colorectal Surgery
• Surgical Complications
• Evidence-Based Medicine

Background:

• Postoperative complications, including anastomotic leak (AL), surgical site infection (SSI), hemorrhage, and colovesical fistula, significantly increase patient morbidity, mortality, hospitalization duration, and healthcare costs following colorectal surgery.
• Effective management strategies for these complications are crucial for improving patient outcomes and resource utilization.

Purpose of the Study:

• To review contemporary evidence on the prevention and diagnosis of major postoperative complications in colorectal surgery.
• To synthesize findings from recent randomized controlled trials, systematic reviews, meta-analyses, and prospective cohort studies.

Main Methods:

• Comprehensive literature review focusing on prevention and diagnosis of AL, SSI, perioperative hemorrhage, and colovesical fistula.
• Analysis of evidence from high-level studies including RCTs, systematic reviews, meta-analyses, and prospective cohort studies.

Main Results:

• Preventive strategies encompass optimizing surgical techniques (minimally invasive/robotic surgery, perfusion assessment, stenting, negative pressure wound therapy), modifying patient factors (obesity, anemia, malnutrition), and implementing system-level interventions (ERAS protocols, beta-blockade, prehabilitation, quality bundles).
• Diagnostic advancements include biomarker surveillance (CRP, procalcitonin), drain fluid analysis, CT imaging, endoscopy, and digital health tools (wearable monitoring, mobile apps).

Conclusions:

• Reducing postoperative complications necessitates a multidisciplinary, protocolized approach.
• Integration of intraoperative technique optimization, structured perioperative care bundles, post-discharge surveillance, and centralization to specialist units is recommended.
