BACKGROUND: Situs inversus totalis is an important discovery for the conduct of clinical surgery. The foreign body in the large intestine can occur due to ingestion or anal introduction. The intestinal perforation is accompanied by high morbidity and becomes a challenge for the surgeons. CASE REPORT: Patient, male, 28 years old, mentally feeble, with pain and abdominal distension for seven days, anorexia for two days, no elimination of gas and feces, no vomiting. On the examination he showed mild dyspnea, dehydration (++/4++), blood pressure= 70X40mmHg, anicteric, tense abdomen, diffusely painful, distended and hypertympanic, hydroaerial sounds absent. The thorax X-ray evidenced cardiac dextroversion, pneumoperitoneum bilaterally with gastric bubble on the right. Due to the general serious condition and confirmed diagnosis of acute abdomen perforation, a hydroelectrolytic vein replacement was held and the patient was submitted to an exploratory celiotomy, observing fecaloid diffuse peritonitis and perforation of sigmoid colon for foreign body taken away followed by mechanical cleaning, washing peritoneal cavity, Hartmann retossigmoidectomy, and bilateral drainage. CONCLUSION: Although a rare entity, the diagnosis of situs inversus totalis must be suspected in a physical examination and confirmed through image examinations, since the anatomic variations can disrupt the performance of clinical surgery.
