Video-assisted retroperitoneal debridement for necrotizing pancreatitis: a single center experience in Colombia.

Introduction: Acute pancreatitis (AP) is a common and potentially lethal disease. Approximately 10-20% of the patients progress to necrotizing pancreatitis (NP). The step-up approach is the gold standard approach to managing an infected necrotizing pancreatitis with acceptable morbidity and mortality rates. Video-assisted retroperitoneal debridement (VARD) has been described as a safe and feasible approach with high success rates. Multiple studies in the American, European, and Asian populations evaluating the outcomes of VARD have been published; nevertheless, outcomes in the Latin American population are unknown. This study aims to describe a single-center experience of VARD for necrotizing pancreatitis in Colombia with a long-term follow-up.

Methods: A prospective cohort study was conducted between 2016 and 2024. All patients over 18 years old who underwent VARD for necrotizing pancreatitis were included. Demographic, clinical variables, and postoperative outcomes at 30-day follow-up were described.

Results: A total of 12 patients were included. The mean age was 55.9 years old (SD 13.73). The median follow-up was 365 days (P25 60; P75 547). Bile origin was the most frequent cause of pancreatitis in 90.1% of the patients. The mean time between diagnosis and surgical management was 78.5 days (SD 22.93). The mean size of the collection was 10.5 cm (SD 3.51). There was no evidence of intraoperative complications. The mean in-hospital length of stay was 65.18 days (SD 26.46). One patient died in a 30-day follow-up. One patient presented an incisional hernia one year after surgery, and there was no evidence of endocrine insufficiency at the follow-up.

Conclusion: According to our data, the VARD procedure presents similar outcomes to those reported in the literature; a standardized procedure following the STEP-UP procedure minimizes the requirement of postoperative drainages. Long-term follow-up should be performed to rule out pancreatic insufficiency.
