Descending colon cancer in a patient with situs inversus totalis: a case report and literature review.

Situs inversus totalis (SIT) is a congenital disorder of anatomical position, and the operation of patients with total visceral inversion often brings great challenges to surgeons. Although there have been previously documented on patients with SIT and colonic cancer, this is the first case report of descending colon cancer in patient with SIT. The current report presents a case of a 67-year-old female patient with descending colon cancer and SIT. After preoperative preparation and discussion, open left hemicolectomy was performed for the patient. The postoperative recovery of the patient was smooth; however, there was a mild lymphatic leakage in the patient, which was cured by conservative treatment for 5 days. The patient was discharged on postoperative Day 10. There was no tumor recurrence or other discomfort in 1 year follow-up period.
