Rectal perforation by inadvertent ingestion of a blister pack: A case report and review of literature

Figure 1 CT scan findings. A: Evidence of an important abdominopelvic peritoneal effusion (black arrowhead), perigastric free air along the gastrocolic ligament and under the anterior abdominal wall (white arrows), and pericardial and bilateral pleural effusions; B: In addition to perigastric free air and under the abdominal wall (white arrows), a microlithiasis (black arrow) of the gallbladder could also be observed.

Figure 2 Postoperative findings. A, B: Blister pill pack with rectal perforation.

Figure 3 Histological findings. A: The whole histological section shows a diverticular structure consisting of mucosa and submucosa with a small rim of longitudinal muscle (× 5); B: Evidence of superficial ulcerations (arrow) with full-thickness mucosal necrosis in the pathological area (× 10); C: Massive inflammatory cell infiltration having a transmural pattern and involving the serosal surface (× 20); D: Massive inflammatory cell infiltration having transmural pattern and involving the serosal surface with partial necrosis (× 20). Hematoxylin and eosin staining.

Figure 4 Upon re-reading of the computed tomography imaging, a radiopaque intraluminal body (white arrow) without any evidence of collection or air leakage was visible in the high rectum.
