Utility of routine postoperative upper gastrointestinal swallow studies following laparoscopic one anastomosis gastric bypass

Figure 1 Upper gastrointestinal study on postoperative day 1 following laparoscopic one anastomosis gastric bypass. A and B: Very faint contrast material passage with near-complete obstruction (A), which resolved a day latter (B).

Figure 2 Upper gastrointestinal study on postoperative day 1. A: Upper gastrointestinal (UGI) study on postoperative day (POD) 1 following laparoscopic one anastomosis gastric bypass (OAGB) showed a small extra luminal tract of contrast material suspicious for a leak (green arrow); B: UGI study on POD 1 following laparoscopic OAGB showed very faint contrast material passage with near-complete obstruction; C: UGI study on POD 1 following laparoscopic revision from band gastroplasty to OAGB showed a large patulous esophagus with a small amount of contrast material passage to the jejunum.
