Pancreatic fistulas belong to the most feared complications after surgery on or near the pancreas, abdominal trauma, or severe pancreatitis. The majority occur in the setting of operative interventions and are called postoperative pancreatic fistulas (POPF). They can lead to various complications, including abscesses, delayed gastric emptying or hemorrhages with a significant impact on morbidity and mortality. Several risk factors have been identified, including smoking, high BMI, male gender, and age. Prophylactic measures and treatment options have been explored but with limited success. This study aimed to analyze the incidence and management of pancreatic fistulas treated in a tertiary referral center, particularly focusing on an endoscopic approach. The data of 60 patients with clinically relevant pancreatic fistulas were analyzed between 2018 and 2021. Different treatment approaches, including conservative management, percutaneous drainage, transpapillary stenting, and endoscopic transmural drainage, were evaluated. An endoscopic transmural approach using lumen-apposing metal stents (LAMS) was used in almost half of this cohort showing promising results, with a high rate of fistula closure in refractory cases and a mean time until closure of 2.7 months. The findings suggest that an endoscopic approach, particularly using LAMS, can be effective in the management of pancreatic fistulas.
