Endoscopic ultrasound guided interventional procedures

Table 1 Comparison between endoscopic vs endoscopic ultrasound-guided drainage of pancreatic pseudocysts

Ref.	Patients and methods	Results
Park et al[10]	Randomised trial of conventional vs EUS guided drainage of pancreatic pseudocysts (n = 60)	EUS guided drainage has higher technical success (94% vs 72%). EUS preferable in non-bulging collections. Complications and pseudocyst resolution similar
Varadarajulu et al[11]	RCT of conventional vs EUS guided drainage (n = 15 each)	Higher technical success in EUS guided procedure (100% vs 33%) with lesser complications
Kahaleh et al[12]	Conventional drainage in bulging pseudocysts and absence of portal hypertension vs EUS guided in rest (n = 99)	No differences in short term or long term success and similar complications
Barthet et al[13]	Algorithm based approach of transpapillary (for small), EUS guided (nonbulging) or Conventional drainage of pseudocysts	EUS guided approach needed for atleast half of the patients

EUS: Endoscopic ultrasound; RCT: Randomized controlled trials.
