Totally laparoscopic liver resection for colorectal metastasis located in Segment 7 in a patient with situs inversus totalis.

Situs inversus totalis (SIT) is a congenital condition consisting of a mirror image of transposition of the abdominal and thoracic organs occurring in about 1:5000 to 1:10 000 adults. We report on a 60-year-old male with a single colorectal liver metastasis in the Segment 7. The patients underwent a totally laparoscopic sub-segmentectomy. Intraoperative approach on a reverse posterior segment was difficult because of left-sided position of the liver. Postoperative course was uneventful and the patient was discharged after 5 days. To our knowledge, only a few cases of open liver resections in patients with SIT have been published. This is, therefore, the first case of laparoscopic liver resection for colorectal liver metastasis in a patient with SIT. We provide the readers with useful tips to perform minimally invasive liver surgery in such patients.
