Robotic intracorporeal continuous double hand-sewn versus laparoscopic assisted extracorporeal anastomosis for left-colectomy: A single-center retrospective cohort.

BACKGROUND

Colorectal cancer patients who underwent intracorporeal colectomy can complete anastomosis by hand-sewn or apparatus. Here we introduce a novel continuous double suture technique for robotic intracorporeal hand-sewn anastomosis in left-colectomy.

METHODS

Patients were divided into robotic intracorporeal continuous double hand-sewn anastomosis (RICD) and the laparoscopic assisted extracorporeal anastomosis (LAEA) group. Intraoperative, postoperative and pathological outcomes were analyzed.

RESULTS

Baseline characteristics had no differences. The overall operative and anastomotic time of RICD were significantly longer, and the incision length was notably shorter. Intraoperative blood loss in RICD was also significantly less. Postoperative complications had no differences. RICD exhibited shorter durations for the enhanced recovery after surgery. The maximum diameter of tumor had no differences, and the number of harvested lymph nodes in RICD was significantly higher.

CONCLUSIONS

RICD has a great potential for technical feasibility, reduced invasiveness and short-term accelerated recovery for left-colectomy requiring further large-scale studies.
