Abstract
To explore the feasibility of nerve plane-sparing laparoscopic radical hysterectomy (NPS-LRH) as a simplified C1-type surgery for cervical cancer patients and to compare this technique with laparoscopic radical hysterectomy (LRH). A retrospective comparative study. An academic tertiary hospital affiliated with the Chinese National Cancer Center. Six hundred fifteen patients with Fédération Internationale de Gynécologie et d'Obstétrique stage Ib and IIa cervical cancer who underwent laparoscopic radical hysterectomy between January 2010 and December 2017 were enrolled. Among them, 263 patients underwent the NPS-LRH surgery, and 352 patients underwent the LRH surgery. Intraoperative data and postoperative outcomes were compared between the 2 groups. NPS-LRH is a simplified type C1 procedure that preserves the ureteral mesentery and its nerve plane, whereas LRH is a type C2 procedure in the Querleu-Morrow surgical classification system. There were no statistically significant differences in age, body mass index, Fédération Internationale de Gynécologie et d'Obstétrique stage, tumor differentiation, pathological type, depth of invasion, lymphovascular space invasion, parametrial tissue invasion, lymphatic metastasis, neoadjuvant chemotherapy, or postoperative adjuvant radiotherapy and chemotherapy between the 2 groups. Compared with the LRH group, the NPS-LRH group had a shorter length of operation (238.7 ± 53.9 minutes vs 259.8 ± 56.6 minutes, p < .01), less intraoperative bleeding (p < .01), more resected lymph nodes (p = .028), shorter duration of urinary catheterization (p < .01), lower incidences of postoperative hydronephrosis (p = .044), less long-term frequent urination (p < .01), less acute urinary incontinence (p < .01), poor bladder sensation (p = .028), and constipation (p = .029). There were no statistically significant differences in the disease-free survival and overall survival between the 2 groups (p = .769 and .973, respectively). NPS-LRH is a simplified, safe, and feasible type C1 operation that had a shorter length of operation, less intraoperative bleeding, more resected lymph nodes, and better postoperative bladder function compared with the LRH group. Further studies are required to assess its benefits on rectal function and long-term prognosis.
