Abdominal X-ray test. (a) Preoperative X-ray test. Findings were within normal limits. (b) Postoperative X-ray test. A cord-like material was captured in the lower right abdomen. (c) X-ray test one month after operation. The cord-like material disappeared.

However, the routine postsurgical abdominal X-ray test showed a cord-like material in the lower right abdomen that was not captured in the preoperative X-ray test performed two months before the operation (Figure 1).
Examination by relaparoscopy. (a) Perioperative photo. No remnant was found where the cord-like material was assumed to exist. (b) Perioperative X-ray test. The shape and position of the material were found to be coincident with the appendix in (a).

During relaparoscopy, we could not find any retained material, and we performed the X-ray test again using a laparoscopic forceps as a mark (Figure 2). The shape and position were found to overlap with the appendix (Figure 2), leading us to conclude that the material captured in the X-ray tests was likely retained barium in the appendix.
