Abstract:
Objective To analyze and compare the clinical efficacy of three-dimensional (3D) and two-dimensional (2D) laparoscopy in total mesorectal resection (TME) and pelvic autonomic nerve protection (PANP).
Methods A retrospective analysis was conducted based on the clinical data of 129 male patients with rectal cancer treated with laparoscopic TME+PANP at Yueyang Hospital of Integrated Traditional Chinese and Western Medicine, Shanghai University of Traditional Chinese Medicine, from June 2016 to June 2021. Among them, 54 patients underwent 3D laparoscopy and were assigned to the observation group; 75 patients who underwent 2D laparoscopy formed the control group. The observation indicators were general condition, intraoperative condition, postoperative complications, urination function, sexual function, and follow-up status of the two groups.
Result All 129 patients completed laparoscopic surgery without any conversion to open surgery or death. The subjective evaluations of image quality, intraperitoneal operation, and depth perception scores by the observation group surgeons were higher than those of the control group ones (P<0.05). There was no statistically significant difference in the incidence of postoperative complications between the two groups (P=0.530). At 6 months after surgery, the observation group had a higher proportion of patients with urinary function ratings of grades I and Ⅱ (P<0.05).
Conclusions The 3D laparoscopic system can obtain clearer and more stereoscopic images, provide stronger depth perception, and reduce the incidence of postoperative urinary dysfunction in male patients undergoing TME+PANP for rectal cancer compared to the 2D system.
