Case report about a successful full robotic radical gastric cancer surgery with intracorporeal robot-sewn anastomosis in a patient with situs inversus totalis and a two-and-a-half-year follow-up study

BACKGROUND During the last decade, total laparoscopic and laparoscopic-assisted distal gastrectomy for gastric cancer patients has been developed as alternatives to open resection. In recent years, this minimally invasive surgery has been extended using robotic-assisted surgery. CASE PRESENTATION Here, we report a surgical intervention using a Da Vinci surgical robot in which a lower two-third stomach resection with subsequent Billroth II gastrojejunostomy was performed. The patient was a 53-year-old male with complete situs inversus gastric cancer who had received 2 cycles of neo-adjuvant oxaliplatin combined with S-1 medication. The operation took 3 h in total without complications. The amount of bleeding was about 50 mL, and on day 5 after the operation, the patient was discharged. CONCLUSIONS This is the first report of a successful robot-assisted gastric cancer resection of advanced gastric cancer in a patient with the anatomical abnormality of situs inversus totalis.
