Introduction: Our report presents a technique of necrotic tissue removal during transmural drainage of walled-off pancreatic necrosis (WOPN) that is an alternative to the one that has already been described in the literature.

Aim: To assess the effectiveness and safety of endoscopic necrosectomy performed during transmural drainage of symptomatic WOPN.

Material and methods: Within the years 2012–2013, 64 patients underwent endoscopic treatment of symptomatic WOPN in our center. Eight patients underwent endoscopic necrosectomy during transmural drainage. Fragments of necrotic tissues were removed from the collection’s cavity under fluoroscopic guidance using a Dormia basket. The results and complications of treatment were compared retrospectively.

Results: Sixty-four patients with WOPN underwent transmural drainage under endoscopic ultrasonography (EUS) guidance. Eight patients (12.5%, 5 women and 3 men, mean age 57.25 years) were qualified for endoscopic necrosectomy. Transmural transgastric access was made in 7 patients and transduodenal access in 1 patient. Additional percutaneous drainage was used in 2 patients. Active drainage was continued for 24 days (11–44 days). The mean number of endoscopic procedures was 4.75 (3–9). The average number of necrosectomy procedures during drainage was 1.75 (1–4). Complications of endotherapy occurred in 2/8 (25%) patients, and they were not directly connected with necrosectomy. Therapeutic success after the end of active drainage was achieved in all patients. During a 6-month follow-up no recurrence of the collection was observed.

Conclusions: Endoscopic necrosectomy under fluoroscopic guidance is an effective and safe method of minimally invasive treatment in a selected group of patients with symptomatic WOPN.
