Morcellation allows the removal of a large uterus and fibroids through small incisions with minimally invasive surgery. It helps to prevent the complications associated with large incisions in both hysterectomy and myomectomy operations. Currently, there is much debate regarding the use of power morcellation in laparoscopic hysterectomy and myomectomy, mainly due to the risk of peritoneal dissemination of undiagnosed uterine sarcomas. Unfortunately, there is no valid pre-operative diagnostic method that can differentiate sarcomas from myomas, and the currently available scientific literature regarding morcellation is insufficient. As the Turkish Society of Minimally Invasive Gynecological Oncology, we present our consensus opinion and suggestions for the preoperative evaluation and morcellation of fibroids, in line with the recent literature.

OBJECTIVE
The use of power morcellation at laparoscopy may worsen survival rates for patients with malignancy. The aim of the present study was to report the outcome of patients with early-stage uterine sarcoma after morcellation or total en-bloc resection, and evaluate potential signs of sarcoma preoperatively.
MATERIAL AND METHODS
This multicenter retrospective study consisted of patients, who underwent surgery for FIGO-stage-1 uterine sarcoma. Twenty-four patients were divided into a non-morcellation group and a morcellation group. Clinical records and the outcomes of patients, including one-, three- and five-year survival rates were reviewed. Preoperative characteristics of patients with sarcoma were compared to those of a control group with uterine myoma (1:4 ratio), matched by age and type of operation.
RESULTS
Obesity was an independent risk factor for uterine myoma. Tumor growth, solitary growth, largest-diameter lesion >8.0 cm, and anechoic areas suggesting necrosis and increased vascularization were significantly more common in the sarcoma group. A large tumor diameter was significantly associated with mortality. Patients in the non-morcellation group had a slightly lower disease-free survival, but poorer overall survival (OS) rates compared to patients in the morcellation group, but neither difference was statistically significant. Patients in the non-morcellation group, who had undergone a re-exploration experienced late recurrence, but no upstaging was evident after the operation.
CONCLUSION
Preoperative ultrasound characteristics could be useful to distinguish sarcoma from leiomyoma of uterus. Morcellation of a sarcoma may increase abdominal and pelvic recurrence rates, but may not be associated with OS in patients with FIGO-stage-1 disease.

Objective Endoscopic enucleation of the prostate has evolved and became popular for the surgical treatment of benign prostatic hyperplasia (BPH) during the last decade. Different surgical techniques have been described so far. We hereby described a new modified two-lobe technique for urologists who are inexperienced in endoscopic enucleation. We aimed here to present the data on a learning curve of this stepwise technique named Demirtaş-Erciyes Enucleation Prostatectomy (DEEP): reverse S-J incision technique and its postoperative outcomes. Material and methods The study included 102 patients who underwent holmium laser enucleation of the prostate (HoLEP) with the DEEP technique between October 2020 and December 2021. Demographic, preoperative, and postoperative variables were recorded. The operation was performed with a 150 W holmium laser system (Quanta System, Varese, Italy) with cutting and coagulation settings of 2J × 50 Hz with virtual basket mode and 2J × 12 Hz in bubble blast mode, respectively. Bladder irrigation was done for one day, and then, on the next day, the urethral catheter was removed. Postoperatively, uroflowmetry studies, continence status, and ejaculation status were recorded during follow-up. The data of all patients were divided into two groups (first 51 and final 51 patients). All variables were analyzed between two groups. Results The mean age of the patients was 68.48±8.74 years. The median Charlson Comorbidity Index (CCI) score was 3. The median International Prostate Symptom Score (IPSS) and International Index of Erectile Function (IIEF) values were 26 (10-35) and 10 (0-25), respectively. Of the patients, 60.8% had Foley catheters due to urinary retention. The median anesthesia time, laser time, enucleation time, morcellation time, and enucleated tissue amount were 102.5 minutes, 17 minutes, 25 minutes, 20 minutes, and 50 g, respectively. Enucleation was performed in two stages in five patients due to bigger prostate volume or incomplete morcellation. The median catheter removal time was 48 hours. In six patients, the postoperative catheterization time was prolonged due to hematuria. The median increase in Qmax was 19.35 mL/second. The overall complication rate was 5.9%, which were all Clavien grade II. Enucleation time, laser time, and anesthesia time were significantly lower in the last 51 patients. Conclusion DEEP enucleation technique seems to provide effective and safe postoperative results for beginners in prostate enucleation.

Review
Uterine fibromas are the most common benign uterine tumors. Although the majority of leiomyomas remain asymptomatic, they can cause serious clinical problems, including abnormal uterine bleeding, pelvic pain, and infertility, which require effective gynecological intervention. Depending on the symptoms as well as patients' preferences, various treatment options are available, such as medical therapy, non-invasive procedures, and surgical methods. Regardless of the extent of the surgery, the preferred option is the laparoscopic approach. To reduce the risk of spreading occult malignancy and myometrial cells associated with fragmentation of the specimen before its removal from the peritoneal cavity, special systems for laparoscopic contained morcellation have been developed. The aim of this review is to present the state-of-the-art contained morcellation. Different types of available retrieval bags are demonstrated. The advantages and difficulties associated with contained morcellation are described. The impact of retrieval bag usage on the course of surgery, as well as the effects of the learning curve, are discussed. The role of contained morcellation in the overall strategy to optimize patient safety is highlighted.

ABSTRACT
This is a short commentary on one of the unusual complication of laparoscopic surgeries, which is difficult to diagnose, thus creating new challenges for a treating surgeon.
BACKGROUND
Uterine fibroid is a common gynaecological condition. But, one of its variants, called as parasitic fibroids, is a rare one and is difficult to diagnose because of their varied presentations. But, with the increase in laparoscopic surgeries, especially where morcellator is used, cases of parasitic fibroid are increasing.
CASE DISCUSSION DESCRIPTION
A forty-two-year-old female presented with abdominal pain, not related to any gastrointestinal or urinary complaints. Patient had history of laparascopic myomectomy followed by morcellation in the past. Ultrasonography was suggestive of mass in right iliac region adjacent to ascending colon with whorl like appearance. Tumour markers were sent, diagnostic laparoscopy was performed which was suggestive of parasitic fibroid, arising from previous surgical port.
CONCLUSION
Complications of parasitic fibroid can occur when morcelletor is used in laparoscopic surgeries, because of the growth of tissue which have spread in pelvic cavity. To prevent this complication, endobag morcellation should be used.
CLINICAL SIGNIFICANCE
History of morcellation, should be asked to females, presenting with varied abdominal complaints, and history of laparoscopic surgery, possibility of parasitic fibroid should be considered in these patients.

Review
In 2014, 9 topics were selected as major advances in clinical research for gynecologic oncology: 2 each in cervical and corpus cancer, 4 in ovarian cancer, and 1 in breast cancer. For cervical cancer, several therapeutic agents showed viable antitumor clinical response in recurrent and metastatic disease: bevacizumab, cediranib, and immunotherapies including human papillomavirus (HPV)-tumor infiltrating lymphocytes and Z-100. The HPV test received FDA approval as the primary screening tool of cervical cancer in women aged 25 and older, based on the results of the ATHENA trial, which suggested that the HPV test was a more sensitive and efficient strategy for cervical cancer screening than methods based solely on cytology. For corpus cancers, results of a phase III Gynecologic Oncology Group (GOG) 249 study of early-stage endometrial cancer with high-intermediate risk factors are followed by the controversial topic of uterine power morcellation in minimally invasive gynecologic surgery. Promising results of phase II studies regarding the effectiveness of olaparib in various ovarian cancer settings are summarized. After a brief review of results from a phase III study on pazopanib maintenance therapy in advanced ovarian cancer, 2 outstanding 2014 ASCO presentations cover the topic of using molecular subtypes in predicting response to bevacizumab. A review of the use of opportunistic bilateral salpingectomy as an ovarian cancer preventive strategy in the general population is presented. Two remarkable studies that discussed the effectiveness of adjuvant ovarian suppression in premenopausal early breast cancer have been selected as the last topics covered in this review.

OBJECTIVE
To examine predictors of enucleation and morcellation times within a large cohort of men undergoing holmium laser enucleation of the prostate (HoLEP) for benign prostatic hypertrophy.
MATERIALS AND METHODS
Preoperative, perioperative, and postoperative clinical characteristics were available from men treated with HoLEP between 1998 and 2013 at Indiana University Health Methodist Hospital. Stepwise linear regression was performed to determine clinical variables which are associated with enucleation and morcellation times.
RESULTS
We identified 960 patients who underwent HoLEP. Average (range) enucleation time was 65.7 (11-245) minutes and morcellation time was 19.7 (3-260) minutes. History of anticoagulation was associated with a small decrease in enucleation time (P = .013) whereas increasing HoLEP specimen weight was associated with increasing enucleation time (P <.001). History of intermittent catheterization, urinary tract infections (UTI), presence of dense prostatic tissue (colloquially referred to as "beach balls"), and increasing specimen weight were associated with increasing morcellation time (P <.05 each). Having HoLEP performed by a less experienced urologist was associated with longer enucleation and morcellation times.
CONCLUSION
Prostate volume is significantly associated with increased enucleation and morcellation times during HoLEP. Additionally, history of UTI and clean intermittent catheterization (CIC) is associated with modest increases in enucleation and morcellation times. Dense enucleated prostate tissue significantly impacts the ability to morcellate effectively. Increasing surgeon experience can significantly improve both enucleation and morcellation efficiency.

Uterine leiomyosarcoma is a rare female reproductive system tumor which is difficult to distinguish from uterine leiomyoma preoperatively. Manual and power morcellation are used to remove the large uterus through the vagina or small abdominal incision. Worse outcome with use of power morcellation is now clear but impact of manual morcellation on survival outcome not established till date. The objective of the present study was to find impact of tumor spillage and to evaluate influencing factors for oncological outcome and prognosis in uterine leiomyosarcoma patients. This is a single-institutional retrospective cohort study including all uterine leiomyosarcoma patients from January 2005 to December 2017. Role of intraoperative tumor spillage and other influencing factors on oncological outcome were assessed. Thirty-three patients with median follow-up period of 49.7 months were evaluated. Stage 1 and absence of tumor spill had significant association with prolonged progression-free survival. Stage 1 uterine leiomyosarcoma (56.8 vs 6.8 months, = < 0.001), intraoperative tumor spillage ( = 0.03) and progression-free survival > 15 months (68.5 vs 12.2 months, = < 0.001) were favourable prognostic factors to predict better survival outcome but unable to establish significance on multivariate analysis. Survival plot did not reach median limit for stage I uterine leiomyosarcoma patients with preoperative suspicion. Age, site of recurrence and mitotic index had no significant association with better survival in the present study. Stage I disease and absence of tumor spillage during surgery improved progression-free survival but did not affect overall survival. Progression-free survival more than 15 months can predict better overall survival.

Uterine leiomyosarcoma is the most common uterine mesenchymal malignancy. The majority present at stage I, and clinical outcomes vary widely. However, no widely accepted risk stratification system for stage I uterine leiomyosarcoma is currently available. We studied 17 routinely evaluated clinicopathologic parameters in 203 stage I uterine leiomyosarcoma from three institutions to generate a novel risk stratification model for these tumors. Mitoses >25 per 2.4 mm (10 high-power fields), atypical mitoses, coagulative necrosis, lymphovascular invasion, and serosal abutment were significantly associated with disease-free and disease-specific survival in univariate and multivariate analyses. These prognostic parameters were each scored as binary ("yes" or "no") variables and fitted to a single optimized algebraic risk model:Risk score = (coagulative necrosis)(1) + (mitoses > 25 per 2.4 mm)(2) + (atypical mitoses)(2) + (lymphovascular invasion)(3) + (serosal abutment)(5)By logistic regression, the risk model was significantly associated with 5-year disease-free (AUC = 0.9270) and 5-year disease-specific survival (AUC = 0.8517). Internal and external validation substantiated the model. The continuous score (range, 0-13) was optimally divided into 3 risk groups with distinct 5-year disease-free and disease-specific survival: low risk (0-2 points), intermediate risk (3-5 points), and high risk (6-13 points) groups. Our novel risk model performed significantly better than alternative uterine leiomyosarcoma risk stratification systems in predicting 5-year disease-free and disease-specific survival in stage I tumors. A simplified risk model, omitting terms for serosal abutment and lymphovascular invasion, can be accurately applied to myomectomy or morcellated specimens. We advocate routine application of this novel risk model in stage I uterine leiomyosarcoma to facilitate patient counseling and proper risk stratification for clinical trials.

OBJECTIVE
In the last 5 years there has been much discussion about the surgical procedure for uterine fibroids, and essentially, also uterine sarcoma. Still there exists no reliable presurgical diagnostic tool to differentiate between benign fibroids and uterine sarcomas. The aim of this study was to confirm the suspected association between intraoperative spread of tumor by morcellation and impaired outcomes in patients with sarcoma.
MATERIAL AND METHODS
After the local ethics commission positively reviewed the study protocol, the oncologic database of our university hospital was retrospectively reviewed for patients with uterine sarcomas over a time period of 13 years (2002-2015). Data was extracted from the medical files and survival information was collected by contacting the patient’s general practitioners if last follow-up-status was older than 6 months. For the analysis, patients were split into two groups with either intrasurgical morcellation (M+) or no morcellation (M-) regarding information provided by the surgical report.
RESULTS
Data on 57 patients with uterine sarcoma were available for further analysis. The median age and body mass index of the patients was 63 years and 27 kg/m², respectively. The sarcoma subtypes were 25 leiomyosarcoma, 19 carcinosarcoma, 9 endometrioid stroma sarcoma, 3 adenosarcoma, and one case without further differentiation. In the majority, no morcellation was performed (M- group, n=44) and 51 patients received open surgery (3 laparoscopic, 1 vaginal, and 2 incomplete surgeries). The median time of follow-up was 31 months. The disease-free survival was 50.5 months and the Cox regression analysis showed a hazard ratio of 3.06 [no significant difference between the two subgroups (p=0.079; 95% confidence interval (CI): 0.9-10.6)]. The overall survival was found as 62.2 months and the Cox regression analysis showed a hazard ratio of 3.216 with a statistically significant difference between the two subgroups (p=0.013; 95% CI: 1.3-8.1).
CONCLUSION
Despite the efforts to find a pre-surgical diagnostic tool, the clinical situation remains unsatisfactory. Overall sarcoma prevalence is low during the last 13 years at our university center, but morcellation occurred in a relevant portion of patients (13 of 57). If sarcoma is suspected or diagnosed then en-bloc resection of the uterus can prolong survival. Thus, morcellation of the uterus and not the surgical technique (en-bloc resection) is the prognostic factor and should be avoided in any suspicious case.
