Abstract

UNASSIGNED : Overlapped delta-shaped anastomosis is a newly developed intracorporeal procedure in totally laparoscopic surgery for colon cancer. We explored the safety and efficacy of three-dimensional (3D) totally laparoscopic surgery for colon cancer using overlapped anastomosis and compared its short-term outcomes with those of two-dimensional (2D) surgery.
UNASSIGNED : From January 2016 to March 2018, 97 colon cancer patients were grouped into the 3D group (43 patients) and the 2D group (54 patients); they underwent totally laparoscopic surgery for colon cancer using overlapped anastomosis by 3D and 2D laparoscopy, respectively. Data regarding the clinical characteristics, surgical and pathological outcomes, postoperative recovery and complications were collected and compared.
UNASSIGNED : These two groups were well balanced in terms of age, gender, body mass index, American Society of Anesthesiologists scores, previous abdominal operation history and preoperative chemotherapy (P>0.05). The overall operation time, intraoperative blood loss and removal method of the specimen were similar between groups (P>0.05), but the anastomosis time was significantly shorter in the 3D group than that in the 2D group (P=0.004). There were no differences in terms of pathological outcomes, postoperative recovery and the postoperative complication rates between the groups (P>0.05). Moreover, no mobility related to the anastomosis, such as anastomotic bleeding, stenosis or leakage, occurred in any patient.
UNASSIGNED : 3D totally laparoscopic surgery for colon cancer using overlapped delta-shaped anastomosis is safe and effective, with satisfactory short-term outcomes. In addition, it is less time-consuming than 2D surgery regarding the overlapped anastomosis procedure.
