Background/Aim:
The recent development of minimally invasive surgery has led to transition from laparoscopic right colectomy (LC) to robot-assisted right colectomy (RC) in Japan. However, it is unclear whether the introduction of RC in municipal hospitals could be as safe as that in high-volume centers in Japan. Therefore, this retrospective study aimed to compare the short-term operative outcomes of RC and LC for right colon cancer at a local municipal hospital in Japan.
Patients And Methods:
Patients with stage I-IV right colon cancer who underwent elective RC or LC between January 2021 and July 2023 were retrospectively analyzed. Patients with double cancer and those who underwent delta anastomosis were excluded. Postoperative surveillance included patient interviews, physical examinations, tumor marker examinations, and whole-body computed tomography every six months.
Results:
Forty patients were analyzed, and 24 (60%) and 16 (40%) patients assigned in the LC and RC groups, respectively, were compared. The operative time, bleeding, postoperative complications, and pathological examinations did not differ significantly between the LC and RC groups.
Conclusion:
RC using overlapping anastomoses was comparable to LC in terms of short-term operative outcomes. The introduction of RC with overlapping anastomosis is a feasible surgical technique.
