Clinical Scorecard: Evaluating the Results of Damage Control Surgery for Perforated Sigmoid Diverticulitis: A Study of Outcomes Before and After the Introduction of a New Treatment Protocol

At a Glance

Key Highlights

• Damage control surgery (DCS) is a two-stage approach showing promise in reducing mortality and stoma rates in critically ill patients with perforated diverticulitis.
• Non-restorative resection (Hartmann’s procedure) is still widely used but associated with high rates of permanent stoma and reversal-related morbidity.
• European and American guidelines recommend primary anastomosis in hemodynamically stable immunocompetent patients, with careful consideration of age and comorbidities.

Guideline-Based Recommendations

Diagnosis

• Diagnosis based on computed tomography (CT) scan identifying free peritoneal contamination.
• Classification using modified Hinchey system (class III and IV for free peritoneal perforation).

Management

• Emergency surgery recommended for hemodynamically unstable or septic patients with complicated acute diverticulitis.
• Laparoscopic lavage for selected patients with purulent peritonitis; resection techniques for fecal peritonitis.
• Primary anastomosis may be performed in stable immunocompetent patients; non-restorative resection reserved for unstable or high-risk patients.
• Damage control surgery recommended by World Society of Emergency Surgery for unstable patients with diffuse peritonitis; considered possible but not yet established in European guidelines.

Monitoring & Follow-up

• Assessment of early (30-day) and late (6-month) postoperative complications using Clavien-Dindo classification and Comprehensive Complication Index.
• Monitoring restoration of bowel continuity and complications post-restoration.
• Follow-up for stoma presence at discharge, 6 months, and 12 months.

Risks

• High risk of life-threatening anastomotic leakage with primary anastomosis in certain patients.
• High colostomy non-reversal rates and reversal-related morbidity associated with non-restorative resection.
• Surgical decision-making complicated by timing (night operations) and surgeon experience.

Patient & Prescribing Data

Patients undergoing emergency surgery for perforated sigmoid diverticulitis before and after implementation of a damage control surgery protocol.

Implementation of a damage control surgery algorithm aims to increase stoma-free discharge rates, reduce early and late complications, and improve rates of bowel continuity restoration compared to conventional strategies.

Clinical Best Practices

• Use CT imaging and modified Hinchey classification for accurate diagnosis and surgical planning.
• Consider damage control surgery as a viable alternative to non-restorative resection in critically ill patients with perforated diverticulitis.
• Select primary anastomosis for hemodynamically stable, immunocompetent patients after evaluating age and comorbidities.
• Apply standardized complication grading systems (Clavien-Dindo, CCI) for postoperative monitoring.
• Ensure multidisciplinary decision-making, especially during off-hours and when performed by less experienced surgeons.
