Therapeutic interventional endoscopic ultrasound in pancreato-biliary disorders: Does it really replace the surgical/percutaneous approach?

Table 2 Summary of comparative studies of endoscopic ultrasound-guided management of pancreatic pseudocysts

Ref.	Design	Cases	Number of patients	Technical success rate	Complication rate
Farias et al[30]	Systematic review and meta-analysis	Pancreatic pseudocysts	342	Risk difference: -0.09 (P = 0.07)	Drainage-related adverse events: risk difference: -0.02 (P = 0.48). General adverse events: risk difference: -0.05 (P = 0.13).
Szakó et al[31]	Meta-analysis	Pseudocysts and walled-off necrosis	842-896	OR 0.59 (P = 0.022): lower clinical success of endoscopic approach	Mortality: OR 0.86 (P = 0.870): similar result. Post-operative length of hospital stay: -3.67 (P < 0.001)
Varadarajulu et al[32]	Randomized trial	Pancreatic pseudocysts	40	Risk difference: -5% (P = 0.5)	Risk difference: -10% (P = 0.24). Median of hospital stay: -4 days (P < 0.001): shorter in endoscopic cytogastrostomy
