BACKGROUND: The purpose of this study was to clarify the oncological safety of reduced-port laparoscopic surgery (single-incision plus one port) (RPS) for patients with rectal cancer.
METHODS: The clinicopathological data of 63 selected patients with clinical Stage I-III (T1-3 and N0-2) rectal cancer who underwent RPS of radical anterior resection between 2012 and 2017 were retrospectively analyzed. The median distance of tumor from anal verge was 11 cm. Ordinarily, a multiport platform with three channels was placed in the 3-cm umbilical incision, and another 5- or 12-mm port was placed in the right lower abdomen.
RESULTS: The median operative time, amount of intraoperative bleeding, number of harvested lymph nodes, and length of distal margin were 272 min, 10 mL, 22 nodes, and 4.0 cm, respectively, and there was one (2%) patient with involvement of the radial margin. There were eight patients (13%) who required additional ports, and one patient (2%) who converted to open surgery. Intra- and postoperative complications occurred in one (2%) and 12 patients (19%), respectively. The median length of postoperative hospital stay was 8 days. The median follow-up period was 79 months, and incisional hernia was observed in 3 (5%) patients at the platform site not the port site, and cancer recurrence occurred in four patients (6%). The 5-year relapse-free and overall survival rates were 100% and 100% in the patients with pathological Stage I disease, 94% and 100% in the patients with pathological Stage II disease, and 83% and 89% in the patients with pathological Stage III disease, respectively.
CONCLUSION: RPS in the selected patients with rectal cancer, performed by an expert laparoscopic surgeon, may be technically safe and oncologically acceptable as well as multiport laparoscopic surgery.
