Direct endoscopic pancreatic necrosectomy is increasingly being utilized to treat infected or symptomatic walled-off necrosis (WON) located close to the stomach or duodenum. Laterally-placed WON has traditionally been treated surgically. We evaluated a less utilized technique of sinus tract endoscopy (STE) for symptomatic laterally-placed WON.


Two hundred seventy-six patients with acute pancreatitis admitted in our hospital, 32 had symptomatic or infected WON requiring intervention. Of the 12 patients with laterally placed WON, 10 were treated by STE. STE was performed with a standard adult gastroscope passed through a percutaneous tract created by the placement of a 32-Fr drain.


Ten patients (7 males; mean age, 43.8 years) underwent STE. Mean number of sessions was 2.3 (range, 1-4), with mean time of 70 minutes for each session (range, 15-70 minutes). While 9 patients had complete success, 1 patient had fever and chose to undergo surgery. Two patients developed pneumoperitoneum, which was treated conservatively. There was no mortality, cutaneous fistula, or recurrence during follow-up.


Laterally placed WON can be successfully managed by STE performed through a percutaneously placed drain. Details of the technique and end-points of STE require further evaluation.
