We report the case of a pelvic and lower abdomen crushing trauma in 37-year-old male patient. The patient had an open lumbar wound, laceration of the psoas muscle, pelvic fracture, a ruptured urogenital diaphragm, and extensive urogenital lacerations. An emergency laparotomy was performed with debridment, urethral reconstruction, and osteosynthesis of the pubic bone. The mobilization of the patient revealed a deep gap, about 8 × 8 cm, in the perineum, with the anus and rectum displaced from their original site. Anal reimplantation was performed, suturing the median raphe, inserting two pelvic drainage tubes, and fashioning a loop transverse colostomy. Closed rectal traumas account for only 4-11% of all rectal traumas. Crushing of the pelvis causes a sudden reduction in its anteroposterior diameter and a corresponding increase in its latero-lateral diameter, together with an abrupt rise in intra-abdominal pressure. The anus is pushed out of the perineal plane due to the divarication of the levator muscles. As suggested in the literature, the standard treatment is wound debridement with immediate or deferred repair, fashioning a diversion colostomy, and repair of the rectum, wherever possible.
