Endoscopic treatment of efferent loop syndrome with insertion of double pigtail stent

Figure 1 Endoscopic finding revealed a narrowed and swollen entrance of the efferent loop.

Figure 2 Gastrograph in study showed nearly complete obstruction of the efferent loop.

Figure 3 Endoscopic stent procedure was performed that double pigtail stent was inserted through efferent loop stenosis and over the guide wire using double-channel endoscope under endoscopic view.

Figure 4 Plain abdominal radiography revealed double pigtail stent to efferent loop (A) and no double pigtail stent and other specific finding (B).

Figure 5 Follow-up gastrograpin and endoscopic study showed free flow of contrast and recovery of narrowed, swollen orifice of the efferent loop.
