A 51 year old patient after a seemingly routine laparoscopic Roux-en-Y bypass returned to the OR on the first post-operative day for a complete obstruction of the roux limb. The posterior wall was included in the misfired staple line used to close the enterotomy defect. We present some visual clues from the original operation that could point to the problem at that time, averting a return trip to the operating room.
