Situs inversus totalis (SIT) is a very rare congenital condition. Situs inversus totalis (SIT) patients who present with gastric cancer have been reported in Japan, China, the United States, and other countries. China has a high incidence of gastric cancer, accounting for 40% of the global annual incidence. Surgical treatment options for situs inversus totalis (SIT) gastric cancer patients are of great concern due to the rare nature of the condition and the anatomical variations. This case aims to demonstrate the utility of robotic surgery in treating situs inversus totalis patients with gastric cancer.
We report a 69-year-old male situs inversus totalis (SIT) gastric cancer patient who successfully underwent a DaVinci robotic-assisted distal gastrectomy with Roux-en-Y reconstruction. The patient had no complications after the operation and was discharged postoperative day 15.
Gastric cancer is an aggressive disease that requires timely diagnosis and appropriate intervention. Unfortunately, many patients present late with gastric cancer and do not benefit from surgical or other appropriate interventions. Patients who are eligible for surgery however still need a clean marginal resection to maximize prognosis, which is not always possible due to complex anatomy or variations as seen in situs inversus totalis. DaVinci robotic surgery system is a new generation of minimally invasive operating systems after conventional laparoscopy, and its visual field clarity, operating flexibility, and instrument stability have obvious advantages over conventional laparoscopic surgery and traditional open surgery.
