A 25-year-old @entity1 delivered her first-born @entity1 weighing 3400 g by full-term normal delivery. Bloody stool developed 3 days after delivery. Colonoscopic examination revealed two linear @entity1066 parallel to the anal column on the posterior side of the rectal ampulla about 5 cm from the anal ring. Coagulated blood was detected at the @entity1066 bottom, suggesting the site of @entity548 . Bowel rest in the absence of oral intake resulted in the disappearance of bloody stool. Three days later colonoscopic examination revealed improvement in the @entity1066 . There was no sign of @entity1142 . A lateral pelvic radiograph showed that the apex of the coccyx was flexed anteriorly. The parturient canal may have physically pressed the rectum against the apex of the coccyx during delivery, causing @entity3137 . Only a few studies have reported the complication of a rectal @entity1066 due to injury during delivery. Furthermore, none of the previous studies has reported a rectal @entity1066 caused by @entity85 .
