RESUMEN

Lateral lymph node metastasis (LLNM) is the main metastatic mode and the major cause of locoregional recurrence of mid-low rectal cancer. Single chemoradiotherapy cannot achieve good local control for LLNM, while the argument against performing lateral lymph node dissection (LLND) is the increased rate of urinary and sexual dysfunction after surgery. Ultra-high definition surgical field and delicate resolution by 4K laparoscopic surgical system will be helpful to achieve good tumor clearance and function preservation by identification and exposure of the important anatomic structures such as pelvic autonomic nerve and internal iliac vessels. Therefore, selective LLND can reduce local recurrence rates, particularly in the pelvic sidewall. LLND with autonomic nerve preservation by 4K laparoscopic system is expected to further decrease the risk of perioperative complications and urinary and sexual dysfunction in appropriate patients with neoadjuvant chemoradiotherapy.

RESUMEN

Objective To investigate effects of rectal cancer to undergo total mesorectal excision (TME)or three space dissection(TSD)with pelvic autonomic nerve preservation(PANP).Methods TME or/ and TSD was applied in 247 Patients with advanced rectal cancer in which 185 cases (74.9 %) underwent PANP(Group P)including TME-PANP(Group Pro)139 cases and TSD-PANP(Group Ps)46 cases.The other 62 cases underwent none-PANP(Group P-)due to tumor invasion.Results There were no death cases for operation inall patients.Group Pm was better than Group Ps in the operation time and the difficulty of proce- dure(P0.05).Conclusion The procedure with TME to preserve pelvic autonomic nerves adapts to the majority of rectal cancer patients.TSD procedure is more complex than TME.Statistically,the survival differ- ence between Patients with TSD and with TME is no defective.The survival time is determined to the tumor's earlier diagnosis and therapy.
