## TL;DR

This case report describes a successful laparoscopic liver tumor removal in a patient with a rare condition where internal organs are mirrored.

## Contribution

The report demonstrates the safety and feasibility of laparoscopic surgery in patients with situs inversus totalis.

## Key findings

- Laparoscopic resection was successfully performed in a patient with situs inversus totalis.
- Comprehensive preoperative preparation and intraoperative cooperation are key to successful outcomes in such cases.

## Abstract

Liver cancer poses a major health burden worldwide. Therefore, surgical resection is an important treatment option for patients with liver cancer. In situs inversus totalis (SIT), a rare genetic condition, organs such as the heart, liver, spleen, and stomach are unpaired in the chest and abdominal cavity and their positions are opposite their usual positions.

We report a case of SIT with a tumor in the right posterior lobe of the liver in a 70-year-old man. This patient was successfully treated with laparoscopic resection.

This case emphasizes that laparoscopic hepatectomy, comprising comprehensive preoperative preparation and fine intraoperative cooperation, is safe and feasible in patients with SIT.
