A new method used in laparoscopic hysterectomy for uterine manipulation: uterine rein technique

Round ligament suspension and vaginal purse-string suture: Newly optimized techniques to prevent tumor spillage in laparoscopic radical trachelectomy for cervical cancer

AIM

The purpose of this study was to investigate the surgical techniques and clinical feasibility of nonuterine manipulator and enclosed colpotomy to avoid cancer cell spillages in laparoscopic radical trachelectomy (LRT) for patients with early-stage cervical cancer.

METHODS

We performed the newly optimized surgical techniques of round ligament suspension and vaginal purse-string suture in LRT in 12 patients with early-stage cervical cancer from May 2019 to October 2020. Surgical information and postoperative results were recorded.

RESULTS

All 12 patients successfully underwent LRT with round ligament suspension and vaginal purse-string suture, and no conversion to laparotomy was required. The median operation time was 268.5 min (range 200-320 min), including 5 min of round ligament suspension, and the median blood loss was 20 mL (range 5-50 mL). The median number of pelvic lymph nodes removed was 27 (range 19-35), and median amounts of paracervical tissue was 24 mm (range 21-26 mm) and vaginal tissue was 18 mm (range 16-26 mm). No intraoperative complication or serious postoperative complications were reported.

CONCLUSION

Round ligament suspension and vaginal purse-string suture techniques are feasible and effective in LRT. They can replace uterine manipulator and unprotected colpotomy with satisfactory perioperative outcomes.

Surgical Approach and Use of Uterine Manipulator Are Not Associated with LVSI in Surgery for Early-stage Cervical Cancer

STUDY OBJECTIVE

In 2018, the Laparoscopic Approach to Cervical Cancer trial reported that patients undergoing minimally invasive surgery for cervical cancer (CC) had poorer outcomes than patients undergoing open surgery. Several hypotheses have been made to explain the results. We aimed to investigate whether laparoscopic procedures and use of a uterine manipulator increase the risk of lymphovascular space invasion (LVSI) in early-stage CC.

DESIGN

A retrospective study.

SETTING

A Chinese women's and children's hospital.

PATIENTS

Patients with early-stage CC who underwent radical hysterectomy in West China Second University Hospital between April 2019 and May 2020.

INTERVENTIONS

Laparoscopic surgery (with uterine manipulator and uterine manipulator-free) and open surgery.

MEASUREMENTS AND MAIN RESULTS

A total of 979 patients diagnosed with CC were registered in West China Second University Hospital for surgical treatment. Of these, 525 patients underwent laparoscopic surgery and 454 patients underwent open surgery. In total, 735 patients with early-stage cancer underwent radical hysterectomy and pelvic lymphadenectomy, including 357 by laparoscopic surgery and 378 by open surgery. For those who underwent radical hysterectomy and pelvic lymphadenectomy, the incidence of LVSI was 48.41% and 47.34% in laparoscopic and open groups, respectively (p = .771). After 1:1 propensity score matching with age, International Federation of Gynecology and Obstetrics stage, pathology, and tumor size, the incidence of LVSI was 45.54% and 51.79% in laparoscopic and open groups, respectively (p = .186). Subdividing the laparoscopic group into uterine manipulator and uterine manipulator-free groups, the incidence of LVSI was 45.22% and 48.35%, respectively (p = .580). After propensity score matching with age, International Federation of Gynecology and Obstetrics stage, pathology, and tumor size, the incidence of LVSI was 45.78% and 55.42% in these 2 groups, respectively (p = .214). Multiple factor analysis revealed that lymph node metastasis and deep stromal invasion were associated with LVSI (p value <.05 in both groups).

CONCLUSION

The surgical approach and use of a uterine manipulator are not associated with LVSI in surgery for early-stage CC. Lymph node metastasis and deep stromal invasion are associated with LVSI.

Uterine manipulator in total laparoscopic hysterectomy: safety and usefulness

The aim of this review is to evaluate the effectiveness and safety of uterine manipulators in facilitating total laparoscopic hysterectomy (TLH). A literature search in MEDLINE, EMBASE, Cochrane Library, UpToDate, SpringerLink, ClinicalKey and Elsevier ScienceDirect databases was performed, and articles describing TLH with or without the use of uterine manipulators were retrieved. Complications related to the use of uterine manipulators are numerous, and although uterine manipulator seems to facilitate TLH, the procedure without a uterine manipulator seems to have a comparable safety and effectiveness, although evidence based on a direct comparison of the two approaches is limited without available controlled trials. Uterine manipulator may provide support in cases of large uteri, severe endometriosis, recto vaginal adhesions and regional anesthesia, while its use may increase complications in cases of vaginal stenosis and nulliparity. Therefore, to perform TLH, the surgeon should individualize for each case if uterine manipulator is needed and which manipulator best suits the surgical procedure requirements and case characteristics. Further studies comparing the two approaches are mandatory.

Laparoscopic Radical Hysterectomy with Enclosed Colpotomy and without the Use of Uterine Manipulator for Early-Stage Cervical Cancer

It was reported recently that minimally invasive radical hysterectomy was associated with worse prognosis than the open abdominal counterpart for the management of early-stage cervical cancer. Uterine manipulator and intracorporeal open colpotomy may be the 2 main suspects responsible for the inferiority. We hypothesize that minimally invasive radical hysterectomy with enclosed colpotomy and without the use of a uterine manipulator will improve survival. Thus, laparoscopic radical hysterectomy with abdominal uterine manipulation and enclosed colpotomy was performed in women with early-stage cervical cancer. The round ligament, the ovary ligament, and the fallopian tube were sutured together for the abdominal manipulation of the uterus. Meanwhile, the upper vagina was ligated before colpotomy to avoid tumor spillage. There were no intraoperative and postoperative complications. The abdominal uterine manipulation and enclosed colpotomy technique, which are both safe and feasible in this study, provide a relatively tumor-free approach for minimally invasive radical hysterectomy. Further investigation of oncologic outcomes in larger prospective studies are needed to confirm our hypothesis.
