Introduction:

Endoscopic ultrasound (EUS)-guided pancreatic cysto-gastrostomy/duodenostomy is the current accepted practice for management of symptomatic pancreatic pseudocysts with insertion of two or more double-pig-tail (DP) stents. There is no much work on the efficacy of using a single wide-caliber DP stent, aiming to decrease the time, complications, and accessories used in the procedure.

Aim of the Work:

The aim of this study was to assess technical and clinical outcomes of using a single wide-caliber DP stent in EUSguided pancreatic pseudocyst drainage.

Methodology:

This multicenter prospective study included 57 patients, from which the 35 patients with symptomatic pancreatic pseudocysts enrolled. Patients with cysts with mul-tiple septations (7 cases) or cyst with >30% necrosis (8 cases) of the cyst content and patients with generalized ascites (4 cases) or patients with major comorbidities (3 cases) were excluded. Patients were followed up within 1 month and 6 months after stent placement to assess complete resolution or a decrease in the sizes of cysts with clinical symptomatic improvement.

Results:

From 57 patients, 35 patients (19 females/16 males, median age 40 years) with a symptomatic pancreatic pseudocyst were referred for EUS-guided drainage. All used stents were 10 Fr DP plastic stents. The median duration of the whole procedure was 16 min. Technical success was achieved in all cases. Clinical success was encountered in 32 patients (91.4%) without re-accumulation on follow-up. Minor adverse events were encountered in 3 patients (8.6%) including post-procedure abdominal pain (1 case) and fever (2 cases).

Conclusion:

We suggest that using a wide-caliber single-pigtail stent for EUS-guided cystogastrostomy is safe and effective with short procedure time, with reduced risks from the insertion of another stent(s).
