Pt operated for D3 adeno. ca, for pppd. with pancreaticogastrostomy  on pod 10 pt is  persistently having ryle's tube aspiration of around 1000cc bilious in nature. Drain output around 300-400cc serous (drain fluid amylase on pod 9 was 40.0) feeding was initiated via FJ but pt develops abdominal distension.

Pt was started on octreotide 100microgm s/c tds to decrease the RT aspiration. But in vain. X-Ray abdomen erect, unremarkable, what next?
