Clinical Report: Outcomes of Damage Control Surgery for Perforated Sigmoid Diverticulitis

Overview

This study compared outcomes before and after implementing a damage control surgery (DCS) protocol for perforated sigmoid diverticulitis. The novel DCS-based algorithm showed promise in reducing stoma rates at discharge and at 12 months, with comparable complication rates and potential cost benefits.

Background

Perforated sigmoid diverticulitis with peritonitis is a life-threatening condition requiring emergency surgery in unstable or septic patients. Surgical options include non-restorative resection (NRR) and primary anastomosis (PRA), with ongoing debate about optimal approaches due to risks such as stoma non-reversal and anastomotic leakage. Damage control surgery (DCS), involving staged laparotomies for source control and stabilization, has emerged as a promising alternative, especially for critically ill patients. This study evaluates a new treatment algorithm incorporating DCS compared to conventional strategies.

Data Highlights

Key Findings

• The introduction of a DCS-based treatment algorithm was associated with a reduction in stoma rates at discharge and at 12-month follow-up compared to conventional strategies.
• Early and late postoperative complication rates were similar between patients treated before and after the DCS protocol implementation.
• DCS allowed for staged surgical management, potentially improving patient stabilization and outcomes in critically ill patients.
• Restoration of bowel continuity rates improved with the new algorithm, reducing the burden of permanent stomas.
• Cost analyses included initial hospitalization, rehabilitation, and subsequent procedures, suggesting economic considerations favoring the DCS approach.

Clinical Implications

Damage control surgery offers a viable alternative to traditional non-restorative resection in managing perforated sigmoid diverticulitis, particularly in unstable patients. Implementing a staged surgical approach may reduce permanent stoma rates without increasing complications, supporting its consideration in emergency surgical protocols. Clinicians should weigh patient stability and comorbidities when selecting surgical strategies.

Conclusion

The study supports the use of a damage control surgery-based algorithm for perforated sigmoid diverticulitis, demonstrating improved stoma outcomes and comparable safety profiles. This approach may enhance patient recovery and reduce long-term morbidity associated with permanent stomas.
