Comparison between double-balloon and single-balloon enteroscopy in therapeutic ERC after Roux-en-Y entero-enteric anastomosis

Figure 1 Radiologic view of a balloon dilation of a stenotic hepaticojejunostomy. The arrows indicate the stenosis.

Figure 2 Three 7 Fr stents were placed through the enteroscope in the enterobiliary anastomosis after balloon dilation of the postoperative stenosis. Bile is spontaneously evacuated through and between the stents.

Figure 3 Endoscopic view of a side-to-side Roux-en-Y entero-enteric anastomosis, showing 3 different directions of jejunal limbs. The upper right directs towards the afferent Roux-en-Y limb. This limb often contains bile and presents antiperistaltic contractions.
