A Comparative Study of Voiding and Sexual Function after Total Mesorectal Excision with Autonomic Nerve Preservation for Rectal Cancer: Laparoscopic Versus Robotic Surgery

摘要: Purpose. To evaluate the protection of urogenital function after robot-assisted total mesorectal excision (R-TME) for rectal cancer compared to those laparoscopic TME (L-TME). Methods. 69 patients who underwent L-TME (n = 39) or R-TME 30) were prospectively enrolled. Their was evaluated by uroflowmetry, a standard questionnaire international prostate symptom score (IPSS) and index erectile (IIEF) before surgery 1, 3, 6, 12 months surgery. The pre- postoperative IPSS IIEF scores detect functional deterioration paired t test each group. How uroflowmetry data deviated from preoperative values (D) statistically between two groups. Results. significantly increased 1 month surgery; recovery decreased urinary took 6 in group (8.2 ± 6.3; P 0.908) but 3 (8.36 5.5; 0.075). DIPSS different groups at (P 0.036). In male (L-TME 20, 18), surgery, gradually recovered over (46.00 16.9; 0.269), within (44.61 13.76; 0.067). DIIEF value not any time groups, an itemized analysis change sexual desire, there significant differences Conclusions. is associated with earlier normal voiding L-TME, although this result needs be verified larger prospective comparative studies.
