Vaginal Closure Before Colpotomy with an Endo-Stapler to Prevent Tumor Spillage in Laparoscopic Surgery for Gynecological Malignancy.

BACKGROUND AND OBJECTIVES: The aim of this study was to define new techniques for performing vaginal closure with endo-staplers to prevent tumor spillage during laparoscopic surgeries for endometrial cancer and early stage cervical cancer. METHODS: Thirteen patients were retrospectively studied for the use of endo-staplers for vaginal closure before colpotomy during laparoscopic surgeries for endometrial cancer and early stage cervical cancer to prevent tumor spillage. RESULTS: There were no short-term or any long-term complication related to the use of the endo-staplers for colpotomy in the surgeries included in this study. CONCLUSION: Use of the endo-staplers to close the vagina before colpotomy according to the technique described is safe and feasible, with prevention of gross spillage of any malignant cells in the peritoneal cavity or vagina, which will further have a favorable oncologic outcome.

Prognostic factors influencing pelvic, extra-pelvic, and intraperitoneal recurrences in lymph node-negative early-stage cervical cancer patients following radical hysterectomy.

OBJECTIVE: The aim of this study was to evaluate the clinicopathologic factors influencing pelvic, extra-pelvic, and intraperitonal recurrences and survival in patients with lymph node-negative early-stage cervical cancer treated with abdominal/laparoscopic/robotic radical hysterectomy (ARH/LRH/RRH). STUDY DESIGN: We retrospectively reviewed clinicopathologic data of 342 patients with FIGO stage IB-IIA cervical cancer (2018 FIGO staging) treated with RH and retroperitonal lymphadenectomy between February 2000 and November 2018. Several clinicopathologic factors such as surgical methods including LRH/RRH-vaginal colpotomy (VC) and LRH/RRH-intracorporeal colpotomy (IC), surgical resection margin, and parametrial/endomyometrial infiltration were selected. Univariate and multivariate Cox proportional hazard regression and logistic regression models were used to determine prognostic factors. RESULTS: The median follow-up time was 54 months (range, 6-202 months). In multivariate analysis, positive endomyometrial infiltration (HR, 13.576; 95 % CI, 2.917-63.179; P = 0.001), positive parametrial resection margin (HR, 32.648; 95 % CI, 2.774-384.181; P = 0.006), and LRH/RRH-IC (HR, 4.752; 95 % CI, 1.154-19.578; P = 0.031) were significantly related to overall survival. Six (26.3 %) out of 21 patients with endomyometrial infiltration showed extra-pelvic recurrences associated with lung, liver, and brain. Three (50.0 %) out of 6 patients with positive parametrial margin showed both pelvic and extra-pelvic metastases, such as pelvis and supraclavicular/paratracheal lymph nodes. Five (62.5 %) out of the eight relapsed patients who received LRH/RRH-IC showed intraperitoneal recurrences including omentum, liver surface, colon serosa, and splenic hilum. CONCLUSIONS: Three risk factors including parametrial margin, endomyometrial infiltration, and laparoscopic IC appear to be involved in pelvic, extra-pelvic, and intraperitoneal recurrences in node-negative early-stage cervical cancer patients following RH. In particular, endomyometrial infiltration may be one of the strongest independent prognostic factors for extra-pelvic recurrence. Adjuvant systemic therapy may be indicated for lymph node-negative early-stage cervical cancer patients with endomyometrial infiltration.

Patterns of recurrence and survival after abdominal versus laparoscopic/robotic radical hysterectomy in patients with early cervical cancer.

AIM: This study investigates the pattern of disease recurrence and identifies the clinicopathologic prognostic factors for patients with International Federation of Gynecology and Obstetrics (FIGO) stage IB and IIA cervical carcinoma treated with laparoscopic/robotic radical hysterectomy (LRH/RRH). METHODS: We conducted a retrospective analysis of 128 patients with FIGO stage IB and IIA cervical cancer. Preoperative examination did not uncover definitive evidence of parametrial invasion or lymph node metastasis in any of the patients; therefore, all patients underwent LRH/RRH with retroperitoneal lymphadenectomy between April 2006 and December 2013. Sites of disease recurrence and all possible clinicopathologic factors related to the risk of disease recurrence were determined. RESULTS: Multivariate analysis demonstrated that laparoscopic intracorporeal colpotomy (P < 0.041, odds ratio 7.038, 95% confidence interval 1.059-15.183) represented a strong prognostic factor related to disease recurrence. We categorized the minimally invasive surgery group into LRH through vaginal colpotomy (LRH-VC; 79 patients) and LRH/RRH through intracorporeal colpotomy (LRH/RRH-IC; 49 patients) according to the colpotomic approaches. Disease recurrence was higher in the LRH/RRH-IC group than in the LRH-VC group (16.3% vs 5.1%, P = 0.057), with five patients in the LRH/RRH-IC group experiencing intraperitoneal spreads. CONCLUSIONS: Total laparoscopic/robotic intracorporeal colpotomy under CO2 pneumoperitoneum may carry a risk of positive vaginal cuff margin, as well as intraperitoneal tumor spreads in patients with early-stage cervical cancer treated with LRH/RRH.
