Laparoscopy-assisted resection of colorectal cancer with situs inversus totalis: A case report and literature review.

BACKGROUND

Situs inversus totalis (SIT) is a rare anomaly in which structures are located opposite to their usual positions. It is not a premalignant condition and the association with colorectal cancer (CRC) is rare. We here report a patient with SIT who underwent laparoscopic radical resection of sigmoid colon cancer, and review the pertinent literature.

CASE SUMMARY: A 53-year-old woman presented with CRC and SIT and underwent a complete examination after admission. The patient then underwent laparoscopic radical resection of sigmoid colon cancer and hyperthermic intraperitoneal chemotherapy. The operation duration was 120 min, and no intraoperative complications occurred. The final pathological report showed stage T4aN0M0. Postoperative chemotherapy was administered and no evidence of recurrence was observed during 18 mo of follow-up.

CONCLUSION

Surgery in a patient with CRC and SIT can be safely performed on the basis of routine preoperative clinical examination.
