Abstract
BACKGROUND

Situs inversus totalis (SIT) is a rare congenital condition in which the structure of the abdominal and thoracic cavities is the mirror image of normal. This anatomic reversal makes laparoscopic surgery difficult when treating colorectal cancer.

CASE SUMMARY

We describe the successful laparoscopic hemicolectomy of a 68-year-old Chinese woman with SIT and ascending colon cancer. Based on preoperative imaging and careful consideration of the patient’s anatomy, the position of the surgeon was modified such that the surgeon stood between her legs, while the surgical assistant and endoscopist stood to the surgeon’s left. Trocar position was also adjusted appropriately. The surgery lasted 178 min, during which the patient lost 50 mL of blood. Pathology analysis of the resected tumor confirmed an adenocarcinoma in clinical stage pT3N0M0, without lymph node involvement. The patient experienced no postoperative complications and was discharged 10 d after surgery.

CONCLUSION

This case illustrates that careful positioning of the surgeon can facilitate laparoscopic surgery of SIT patients.

Core Tip: Situs inversus totalis (SIT) is a rare congenital anomaly in which the organs in the chest and abdomen are located in a mirror image reversal of their normal positions. We present a rare case of SIT accompanied by colon cancer. After careful consideration of the patient’s anatomy, we modified the position of the surgeon to enable successful laparoscopic hemicolectomy. This case highlights that careful positioning of the surgeon can make laparoscopic surgery feasible and safe for SIT patients.
