Vaginal morcellation: A new strategy for large gynecological malignant tumor extraction A pilot study

Objective. Evaluate feasibility and safety of a novel technique for uterine morcellation in patients scheduled for laparoscopic treatment of gynecologic malignances. Background. The laparoscopic management of uterine malignancies is progressively gaining importance and popularity over laparotomy. Nevertheless, minimal invasive surgery is of limited use when patients have enlarged uterus or narrow vagina. In these cases, conventional uterus morcellation could be a solution but should not be recommended due to risks of tumor dissemination. Methods. Prospective pilot study of women with endometrial cancer in which uterus removal was a realistic concern due to both organ size and proportionality. Brief technique description: after completion of total laparoscopic hysterectomy and bilateral anexectomy, a nylon with polyurethane Lapsac (R) is vaginally inserted into the abdomen; the specimen is placed inside the pouch that will be closed and rotated 180 degrees toward the vaginal vault and, posteriorly, pushed into the vaginal canal; in the transvaginal phase, the surgeon pulls the edges of the bag up to vaginal introitus and all vaginal walls will be covered; inside the pouch, the operator performs a uterus bisection-morcellation. Results. In our series of 8 cases, we achieved successful completion in all patients, without conversion to laparotomy. Average operative time, blood loss and length of hospitalization were favorable. One patient presented with a vesicovaginal fistula. Conclusion. The vaginal morcellation following oncologic principles is a feasible method that permits a rapid uterine extraction and may avoid a number of unnecessary laparotomies. Further studies are needed to confirm the oncological safety of the technique. (C) 2012 Elsevier Inc. All rights reserved.

Safe vaginal uterine morcellation following total laparoscopic hysterectomy.

The minimally invasive approach for hysterectomy with proven benefits and lower morbidity has become the gold standard, even in women with large uterine masses. Most women with a malignant condition present with abnormal vaginal bleeding and/or suspicious imaging such that few are diagnosed by final histopathology after surgery. However, if a malignancy is not diagnosed preoperatively, intraabdominal morcellation for uterus extraction has an increased risk for potential tumor spread and peritoneal metastases, especially in cases of unexpected leiomyosarcoma. We describe a simple method to wrap the uterus in a contained environment with a plastic bag through the posterior vaginal fornix prior to conventional coring morcellation for vaginal extraction in total laparoscopic hysterectomy. We further describe our experience with a risk stratification and treatment algorithm to implement this procedure in daily routine. A video and an illustrating sketch demonstrate the simplicity and safety of the procedure.

Factors Affecting De Novo Urinary Retention after Holmium Laser Enucleation of the Prostate

Objective Patients can experience urinary retention (UR) after Holmium laser enucleation of the prostate (HoLEP) that requires bladder distension during the procedure. The aim of this retrospective study is to identify factors affecting the UR after HoLEP. Materials and Methods 336 patients, which underwent HoLEP for a symptomatic benign prostatic hyperplasia between July 2008 and March 2012, were included in this study. Urethral catheters were routinely removed one or two days after surgery. UR was defined as the need for an indwelling catheter placement following a failure to void after catheter removal. Demographic and clinical parameters were compared between the UR (n = 37) and the non-urinary retention (non-UR; n = 299) groups. Results The mean age of patients was 68.3 (±6.5) years and the mean operative time was 75.3 (±37.4) min. Thirty seven patients (11.0%) experienced a postoperative UR. UR patients voided catheter free an average of 1.9 (±1.7) days after UR. With regard to the causes of UR, 24 (7.1%) and 13 (3.9%) patients experienced a blood clot-related UR and a non-clot related UR respectively. Using multivariate analysis (p<0.05), we found significant differences between the UR and the non-UR groups with regard to a morcellation efficiency (OR 0.701, 95% CI 0.498–0.988) and a bleeding-related complication, such as, a reoperation for bleeding (OR 0.039, 95% CI 0.004–0.383) or a transfusion (OR 0.144, 95% CI 0.027–0.877). Age, history of diabetes, prostate volume, pre-operative post-void residual, bladder contractility index, learning curve, and operative time were not significantly associated with the UR (p>0.05). Conclusions De novo UR after HoLEP was found to be self-limited and it was not related to learning curve, patient age, diabetes, or operative time. Efficient morcellation and careful control of bleeding, which reduces clot formation, decrease the risk of UR after HoLEP.
