Factors affecting the selection of minimally invasive surgery for stage 0/I colorectal cancer

• Old age and surgeons were barriers to the choice of minimally invasive surgery (MIS) for stage 0/I colorectal cancer.
• The short-term and oncologic outcomes of MIS were comparable to those of open procedures.
• It is safe to expand the indication for MIS to elderly patients.

PurposeTo evaluate which factors affect selection of minimally invasive surgery (MIS) or open procedures for patients with stage 0/I colorectal cancer. The short-term and oncologic outcomes of MIS were also compared to those of open procedures.MethodsA total of 181 consecutive patients underwent either MIS (laparoscopy: n = 146, robot: n = 8) or open (n = 27) colorectal resection for stage 0/I disease.ResultsElderly patients (≥80) were more common in the open procedure group (22.2%) than the MIS (7.8%) group (p = .02). Surgeon A performed more MIS procedures than surgeon B (p = .003). There were no differences in the 30-day complication rate between open (37%) and MIS (21.4%) groups (p = .08). Time to tolerable diet (p = .002) and length of hospital stay (p = .02) were shorter in the MIS group. There were no differences in the cancer-specific survival (p = .71) and recurrence-free survival rates (p = .67) between open and MIS procedures.ConclusionsPatient factors (old age) and surgeon factors (surgeon B) were barriers to the choice of MIS. Old age and operating surgeons were not associated with adverse 30-day complications. The short-term and oncologic outcomes of MIS were comparable to those of open procedures. It is safe to expand the indication for MIS to elderly patients.
