🔬 Practice‑Changing Findings
Evidence from RCTs and meta‑analyses published in the last 12 months.

1. SAGES white paper on antibiotic omission in the management of acute uncomplicated diverticulitis: why, when, who, and most importantly, how.

Surgical endoscopy (2025) - Practice Guideline

Key Findings

  • Randomized trial evidence found no superiority of routine antibiotics versus selective omission in uncomplicated acute diverticulitis.
  • Appropriate omission candidates were immunocompetent, non-septic patients with mild disease features on imaging, with reduced unnecessary antibiotic exposure.

📋 Practice Implication: Adopt protocolized no-routine-antibiotic care for low-risk uncomplicated presentations, with explicit return precautions and early reassessment triggers.

2. The role of non-operative management (NOM) in perforated diverticulitis: a systematic review.

Langenbeck's archives of surgery (2026) - Systematic Review

Key Findings

  • Pooled success for conservative management in perforated diverticulitis with extraluminal air was 90.2% overall.
  • Success differed sharply by air pattern: 89.9% for pericolic air versus 27.8% for distant free air.

📋 Practice Implication: Use CT-defined air distribution to triage care: non-operative pathways for stable pericolic-air cases, with lower threshold for surgery when distant free air is present.

3. Ultrasound accuracy in acute diverticulitis: A systematic review and Meta-analysis.

The American journal of emergency medicine (2025) - Meta-Analysis

Key Findings

  • Ultrasound achieved pooled sensitivity 92.5% and specificity 87.7% for diagnosing acute diverticulitis compared with CT standards.
  • For complicated disease, specificity remained high at 98.2% while sensitivity fell to 58.3%, limiting exclusion reliability.

📋 Practice Implication: Use ultrasound as an efficient first test in straightforward cases, but escalate to CT promptly when complication risk or diagnostic uncertainty remains.

💡 Summary

Recent evidence supports selective, risk-stratified management of acute diverticulitis rather than automatic escalation of antibiotics or surgery. For uncomplicated disease, outcomes are similar with antibiotic omission in carefully selected patients, while imaging phenotype and hemodynamic context should drive management in perforated disease. Ultrasound can efficiently support early diagnosis, but CT remains critical when complications are a concern.
