Perioperative complication rate in 1706 patients after a standardized laparoscopic supracervical hysterectomy technique

Transvaginal Natural Orifice Transluminal Endoscopic Surgery (vNOTES) in Urogynecological Surgery: A Systematic Review

Background: Minimally invasive surgery could improve cosmetic outcomes and reduce the risks of surgical injury with less postoperative pain and a quicker patient's discharge. Recently, transvaginal natural orifice transluminal endoscopic surgery (vNOTES) has been introduced in urogynecology with exciting results. Evidence Acquisition: After PROSPERO registration (n°CRD42023406815), we performed a comprehensive literature search on Pubmed, Embase, and Cochrane CENTRAL, including peer-reviewed studies evaluating transvaginal natural orifice transluminal endoscopic surgery. No limits on time or type of study were applied. Evidence synthesis: Overall, 12 manuscripts were included in the analysis. Seven studies evaluated uterosacral ligament suspension, four studies evaluated sacral colpopexy, three evaluated sacrospinous ligament suspension, and one study evaluated lateral suspension. Overall success rates were high (>90%); however, definitions of success were heterogeneous. In terms of complication, most of the studies reported low-grade complications (Clavien-Dindo I and II); only two patients needed mesh removal because of mesh exposure. The risk of bias of the trials was rated in the medium to high-risk category. Conclusions: The present review highlights important initial results for vNOTES. Future randomized clinical trials are needed to better define its role in the management of urogynecological procedures.

The Beginner Laparoscopists Trends in the Learning Process of Laparoscopy for Adnexal Gynecological Pathologies-The Experience of Our Center

BACKGROUND

Laparoscopy for benign ovarian pathology is the appropriate surgical approach and it has many well-known advantages. Minimal invasive gynecological surgery increases the quality of life of the patient. The learning process of laparoscopy is difficult and requires many interventions to acquire manual skills. The objectives of the study were to assess the learning process of laparoscopy for adnexal pathology surgery performed by beginner laparoscopists.

MATERIALS AND METHODS

This study included three gynecological surgeons who were beginners in laparoscopy and who were named A, B, and C. We collected information about patients, diagnosis, surgical technique, and complications.

RESULTS

We have analyzed the data from 159 patients. The most frequent primary diagnosis was functional ovarian cyst, and the laparoscopic cystectomy was performed in 49.1% of interventions. The need to convert a laparoscopy into laparotomy was necessary in 1.3% of patients. There were no cases of reintervention, blood transfusion, or ureteral lesions. The duration of the surgical intervention varied statistically significantly according to patient's BMI and to the surgeon. After 20 laparoscopic interventions, a significant improvement was found in the time needed to perform ovarian cystectomy (operators A and B) and salpingectomy (operator C).

CONCLUSIONS

The process of learning laparoscopy is laborious and difficult. We found a significant decrease in operating time after a twenty laparoscopic interventions.

Systematic review of urological injury during caesarean section and hysterectomy

INTRODUCTION AND HYPOTHESIS

We aim to review iatrogenic bladder and ureteric injuries sustained during caesarean section and hysterectomy.

METHODS

A search of Cochrane, Embase, Medline and grey literature was performed using methods pre-published on PROSPERO. Eligible studies described iatrogenic bladder or ureter injury rates during caesarean section or hysterectomy. The 15 largest studies were included for each procedure sub-type and meta-analyses performed. The primary outcome was injury incidence. Secondary outcomes were risk factors and preventative measures.

RESULTS

Ninety-six eligible studies were identified, representing 1,741,894 women. Amongst women undergoing caesarean section, weighted pooled rates of bladder or ureteric injury per 100,000 procedures were 267 or 9 events respectively. Injury rates during hysterectomy varied by approach and pathological condition. Weighted pooled mean rates for bladder injury were 212-997 events per 100,000 procedures for all approaches (open, vaginal, laparoscopic, laparoscopically assisted vaginal and robot assisted) and all pathological conditions (benign, malignant, any), except for open peripartum hysterectomy (6,279 events) and laparoscopic hysterectomy for malignancy (1,553 events). Similarly, weighted pooled mean rates for ureteric injury were 9-577 events per 100,000 procedures for all hysterectomy approaches and pathologies, except for open peripartum hysterectomy (666 events) and laparoscopic hysterectomy for malignancy (814 events). Surgeon inexperience was the prime risk factor for injury, and improved anatomical knowledge the leading preventative strategy.

CONCLUSIONS

Caesarean section and most types of hysterectomy carry low rates of urological injury. Obstetricians and gynaecologists should counsel the patient for her individual risk of injury, prospectively establish risk factors and implement preventative strategies.

Prophylactic Salpingectomy during Hysterectomy for Benign Disease: A Prospective Study to Evaluate High-Grade Serous Ovarian Carcinoma Precursors

Recent findings suggest that high-grade serous ovarian cancer can originate in the fallopian tube. Not only has that made the identification of precursor lesions pivotal in early detection and prevention of these cancers, prophylactic salpingectomy alongside hysterectomy for benign indications has been increasingly proposed as well. The present prospective single-center study included 273 women who underwent opportunistic salpingectomy alongside laparoscopic supracervical hysterectomy. Uterine and tubal histopathological results as well as intra- and postoperative complications were evaluated. The complication rate was 3.3%, of which none were caused by salpingectomy. Uterine histopathology diagnosed 181 patients (66.8%) with uterine myomas, 60 patients (22.1%) with adenomyosis, 29 patients (10.7%) with adenomyomatosis, and, 1 patient (0.4%) without pathological abnormality. p53 signatures were detected in 221 right fallopian tubes (80.9%) and in 229 left tubes (83.9%). In total, 8 patients showed bilateral STIL (2.9%), whereas in 1 patient (0.4%) STIL was detected in the left tube only. No STIC were detected. Laparoscopic opportunistic salpingectomy is demonstrated to be both safe and feasible. It appears to be promising to reduce the risk for ovarian cancer, yet more studies are needed to undoubtedly confirm this.

Evaluation of complications, conversion rate, malignancy rate, and, surgeon's experience in laparoscopic assisted supracervical hysterectomy (LASH) of 1274 large uteri: A retrospective study

INTRODUCTION

Hysterectomy now belongs to standard gynecological procedures. Moreover, a shift towards laparoscopic techniques is ever more apparent as they provide many advantages such as less traumatization and shorter convalescence. Large uteri are still mentioned as contraindications for laparoscopic hysterectomy even though those patients might benefit from the lower morbidity associated with minimal invasive techniques. In this study, the largest reported so far, we analyzed intraoperative and postoperative complications as well as the surgeon's experience of laparoscopic assisted supracervical hysterectomy (LASH) in patients with a uterus weight over 500 g.

MATERIAL AND METHODS

The present retrospective study, between June 27, 1998 and August 31, 2019, evaluates 1274 patients with a uterus weight over 500 g who were treated with LASH for benign uterine diseases at the Clinic for Minimal Invasive Surgery (Berlin, Germany). All surgeries were performed by one of four in-house surgeons with experience in LASH: they had performed at least 500 LASH procedures before the study. Patients receiving surgical treatment for malignant tumors were not included in the study. Major and minor intraoperative and postoperative complications were recorded and evaluated. Additionally, medical files were evaluated for demographic data, American Society of Anesthesiologists score (I-IV), name of the surgeon, duration and indication for surgery, history of previous gynecological procedures and concomitant surgical interventions, weight of removed uterine tissue, duration of postoperative hospitalization in patients with complications, intraoperative conversion from laparoscopy to laparotomy, and malignancy rate.

RESULTS

The mean age was 47.0 ± 7.3 years and mean body mass index was 25.6 ± 7.1 kg/m² . Average parity was 1.04 ± 1.57. Average uterus weight was 761.8 ± 317.9 g (500-4065 g). The mean duration of surgery was 96.9 ± 49.5 min; 54% of all patients were treated without concomitant intervention, conversion rate was 2.12%. The malignancy rate was 0.4% and the complication rate was 6.81% with 1.36% intraoperative complications and 5.45% postoperative complications.

CONCLUSIONS

The overall low complication and malignancy rates observed in this study allow us to present LASH as a safe and efficient alternative laparoscopic approach to remove uteri of any size in the hands of experienced surgeons.

Total surgical time in laparoscopic supracervical hysterectomy with laparoscopic in-bag-morcellation compared to laparoscopic supracervical hysterectomy with uncontained morcellation

Background

A possible solution to the problem of cell dissemination through laparoscopic uncontained morcellation during laparoscopic supracervical hysterectomy (LASH) is the use of laparoscopic in-bag morcellation. One criticism regarding the use of in-bag morcellation is the additional surgical time associated with this procedure.

Objectives

In this retrospective study we compared the total surgical time in LASH with laparoscopic in-bag morcellation (107 cases from 2016-2018) and LASH with uncontained morcellation (47 cases from 2015-2017).

Materials and Methods

All surgeries were performed in the same department of minimally invasive gynaecological surgery by a total of three experienced surgeons for the indication of bleeding disorder and / or dysmenorrhea.

Main outcome measures

We measured and compared total surgical time, surgical outcome, blood loss and complications in LASH with in-bag morcellation and with uncontained morcellation.

Results

Total surgical time in both procedures do not show a significant difference. Considering the learning curve in laparoscopic bag use, the total surgical time in LASH with laparoscopic in-bag morcellation is shorter than total surgical time in LASH with uncontained morcellation. Laparoscopic in-bag morcellation consumes time for bag use and handling, but saves time as it eliminates the need for meticulous sampling of lost tissue fragments and the complex lavage of the peritoneal cavity after morcellation. There is no difference between both groups in terms of blood loss, complications and surgical results.

Conclusion/What is new?

We conclude that LASH with in-bag morcellation is not related to additional surgical time when compared to LASH with uncontained morcellation.

The influence of persistent bleeding after supracervical hysterectomy on depressive and anxious symptoms: a prospective bicenter study

PURPOSE

Postoperative spotting is a frequent adverse symptom after laparoscopic supracervical hysterectomy (LSH). The conical excision (eLSH) reduces the postoperative spotting rate, but data in a larger collective are still rare and inconsistent. The influence of persistent bleeding on the anxious and depressive symptoms has not been analyzed yet.

METHODS

311 patients, who underwent a laparoscopic supracervical hysterectomy with conical excision (n = 163), or with straight cervical resection (n = 148) were included. Anxious and depressive symptoms and postoperative spotting were recorded before operation, at 3 month follow-up and at 1 year follow-up in both operative groups using a validated questionnaire (German version of Hospital Anxiety and Depression Scale, HADS-D) and additional questions concerning the frequency and impact of bleeding. Statistical analysis included the impairment of bleeding as well as its impact on depressive and anxious symptoms for both groups.

RESULTS

11.5% after eLSH and 15.5% after LSH reported spotting after 1 year. Supracervical hysterectomy significantly improves depressive and anxious symptoms at 3 and at 12 month follow-up for both groups (p < 0.001) independent on residual spotting. Patients with a preoperative continuous bleeding showed a maximum benefit independent on operative method.

CONCLUSION

Laparoscopic supracervical hysterectomy has a positive effect on anxious and depressive symptoms in the short-term and intermediate-term follow-up. The conical excision of the cervical stump reduces postoperative spotting rate, but has no explicit advantage on symptoms of depression or anxiety, irrespective of residual postoperative spotting.

Single-port laparoscopic hysterectomy for uteri greater than 500 grams

OBJECTIVES

To study the operative outcomes of single-port laparoscopic hysterectomy in uteri greater than 500 g, using either laparoscopic assisted vaginal hysterectomy (LAVH) or laparoscopic supracervical hysterectomy (LSH).

MATERIALS AND METHODS

78 patients were included in a single institute by a single surgeon from March, 2013 to January, 2018.

RESULTS

The median uterine weight was 686.5 g. Larger uterine weight was correlated with longer operative time and greater estimated blood loss. Two types of operations were performed: LAVH (n = 55) or LSH (n = 23). There were no differences in operative time (150.2 ± 45.1 vs. 158.6 ± 82.1, P = 0.66) and estimated blood loss (365.8 ± 298.5 vs. 356.5 ± 46.6, ml, P = 0.94) between LAVH and LSH. However, patients in LAVH had more excess blood loss (>500 mL) compared with LSH (32.7% vs. 21.7%, P = 0.42). In the later study period, the operative time was shorter and complication rates were lower. Such differences were especially significant in the LAVH group. By multiple regression analysis, operative time was independently correlated with age, body mass index, estimated blood loss and uterine weight in LAVH. The correlation between operative time and uterine weight in LSH was attenuated by estimated blood loss. Estimated blood loss was the dominant factor correlated with longer operative time in LSH.

CONCLUSIONS

Both LAVH and LSH could be feasible in uteri greater than 500 g. LSH appeared to have less complication and less blood loss than LAVH. Operative time was correlated significantly with bleeding amount. Therefore, better bleeding control and surgical experience were warrants for single-port laparoscopic hysterectomy in uteri greater than 500 g.

Torsion of intestinal parasitic myoma after laparoscopic morcellation: a case report

Uterine fibroids represent the most common type of benign tumor of female genital tract with rate of incidence between 20% and 30% in women older than 35 years. According to current bibliography, the percentage is still increasing due to the fact that many women are postponing their reproductive mapping. Laparoscopic morcellation of uterine fibroids and uterus specimen after hysterectomies has great clinical significance, concerning dissemination and implantation of uterine fragments inside the peritoneal cavity. Parasitic myomas reveal a rare entity, reflecting a broad spectrum of pathogenesis. In cases of parasitic uterine fibroids surgical dissection is mandatory to avoid signs of malignancy.

Iatrogenic parasitic myoma and iatrogenic adenomyoma after laparoscopic morcellation: A mini-review

Laparoscopy is widely recognized as a procedure of choice for gynaecological surgery. Myomectomy and hysterectomy are the most frequently performed surgical procedures in gynaecology. A morcellator is often used in myomectomies or subtotal hysterectomies, but morcellation may cause rare complications, such as parasitic iatrogenic myoma or adenomyoma. To improve patient counselling, proper risk estimation as well as risk factor identification should be acknowledged. This article aimed to review the literature on parasitic myoma and adenomyoma and to compare these diseases in terms of clinical, surgical, and prognostic factors. All published literature (case series and case reports) on iatrogenic myoma and adenomyoma was reviewed using PubMed/MEDLINE and ScienceDirect resources. Despite both conditions having an iatrogenic origin, iatrogenic parasitic myoma and adenomyoma are two different entities in terms of clinical manifestations as well as intraoperative particularities, with a common point: iatrogenic complication. A possible solution to avoid these iatrogenic complications is by using in-bag morcellation or switching to another surgical procedure (e.g., a vaginal or abdominal approach). It is concluded that parasitic myoma and iatrogenic adenomyoma are two different iatrogenic morcellator-related complications. In patients with a history of uterus or myoma morcellation who report pelvic symptoms, iatrogenic parasitic myoma or adenomyoma should be considered in the differential diagnosis.

Occult Malignancy Rate of 1498 Hysterectomies or Myomectomies with Morcellation: A Retrospective Single-Arm Study

Background and Purpose

Since April 2014, the FDA warns against the use of morcellation during minimally invasive uterine surgery because of the risk of occult malignant spreading in the abdominal cavity. It is clear, however, that more studies are needed to define the incidence of occult uterine cancers, its risk factors, preoperative identification and postoperative follow-up. The present retrospective single-arm study defines the prevalence of occult uterine malignancies in a large group of patients treated with hysterectomy or myomectomy for benign indications.

Methods

In the year of 2014, 1498 women admitted for a myomectomy or hysterectomy in benign conditions at the clinic of minimally invasive surgery (Minimal Invasive Chirurgie or MIC) in Berlin (Germany) were included in this study. The morcellated uterine specimens of operated patients were histologically analyzed for the presence of cancerous tissue.

Results

We detected malignancies in three of the 1498 women (0.2%): two patients had endometrial cancer, while we observed cervical cancer in situ in the third patient. No sarcoma was found.

Conclusion

We detected a very low prevalence of occult uterine malignancy which is in line with several other recent studies. To define a clear policy on the use of morcellation, more studies are required. In the meantime, patients should be informed about the risks of morcellation in case of undetected cancer prior to surgery.

Unexpected uterine sarcomas in 4478 patients with electric power morcellation for leiomyomas

OBJECTIVES

Our objective is to investigate the prevalence, pathology and prognosis of uterine sarcomas in laparoscopic hysterectomy/myomectomy with electric power morcellation for presumed leiomyomas.

STUDY DESIGN

We retrospectively reviewed patients with laparoscopic power morcellation (LPM) for presumed leiomyomas in a Chinese tertiary institution by chart review from September 1, 2013 to December 31, 2016.

RESULTS

Twenty-four in 4478 patients (0.54%) with LPM for presumed leiomyomas had unexpected cancers. The patients showed the highest frequency of occult cancers (10/375, 2.6%) at 51-60 years and lowest (0/255) before 30 years. The pathology included 14 endometrial stromal sarcomas (ESS) (low-grade 12 and high-grade 2), 9 leiomyosarcomas, and 1 malignant mixed mesodermal tumor. The patients underwent abdominal re-exploration including total hysterectomy with bilateral salpingo-oophorectomy and staging surgery. Three patients were at advanced FIGO stage (IIIb-IVb) and 21 at stage I. Seven patients recurred within 1-25 (mean 6.29) months including 5 leiomyosarcomas, 1 high-grade and 1 low-grade ESS. Four recurrent patients with leiomyosarcomas and one with high-grade ESS died of disease in 1-3 months. Seventeen patients had no relapse and were alive for 6-41 (mean 24) months.

CONCLUSIONS

Our study suggests that patients with LPM for presumed leiomyomas appear to have a considerable risk of unexpected cancers. Moreover, morcellation is potentially associated with adverse prognosis in patients with high-grade sarcomas. Informed consent on unexpected cancers that should be discussed before morcellation.

LASH in Severely Enlarged Uterine Leiomyoma: Removal of a Uterus of 4065 g

Today, even though minimally invasive approaches have become standard worldwide, large uteri are still mainly removed by means of open abdominal approaches. The present case describes the successful removal of the largest uterus ever reported (4065 g) by means of laparoscopy-assisted supracervical hysterectomy (LASH). We combined LASH with the changeover technique which allows a better access and view. We further explain how this approach allows for the safe minimally invasive removal of uteri of any size.

Non-malignant Sequelae after Unconfined Power Morcellation

STUDY OBJECTIVE

To identify the incidence of repeat surgery and subsequent findings after the performance of unconfined uterine power morcellation.

DESIGN

A retrospective descriptive study (Canadian Task Force classification II-2).

SETTING

Southern California Kaiser Permanente Medical Centers.

PATIENTS

Women (N = 5154) who underwent laparoscopic supracervical hysterectomy with unconfined power morcellation.

MEASUREMENTS AND MAIN RESULTS

Of the 5154 cases, 279 (5.41%) underwent subsequent reoperation with a median of 24 months after index surgery. The most common clinical complaint leading to laparoscopic supracervical hysterectomy was symptomatic leiomyoma (n = 135, 48.4%) and abnormal uterine bleeding (n = 94, 33.7%). The most common indication for reoperation was a symptomatic adnexal mass (n = 87, 31.2%) followed by pelvic pain (n = 83, 29.7%). The majority (n = 128, 60.4%) of subsequent non-urogynecologic-related reoperations resulted in benign pathology. Endometriosis was the primary pathologic diagnosis in 65 of 279 (23.3%) of the reoperative cases; this was not previously documented in 86% (n = 57/65) of these cases. The overall frequency of subsequent pathology was endometriosis (65/5154, 1.26%), disseminated leiomyomatosis (18/5154, 0.35%), and new malignancy (11/5154, 0.21%).

CONCLUSION

Morcellation of nonmalignant tissue is not without consequence. Pathology confirmed endometriosis was documented for the first time in 20.4% of patients who underwent a second surgery. This finding raises the suspicion that morcellation and dispersion of the uterine specimen may be associated in the development of endometriosis.

Laparoscopic Supracervical Hysterectomy with In-Bag Morcellation in Very Large Uterus

Laparoscopic supracervical hysterectomy (LASH) is a safe and fast minimally invasive approach in hysterectomy. In order to extract the uterine body from the abdominal cavity, one condition for LASH is the morcellation of the tissue. The intra-abdominal dissemination of benign and occult malignant uterine cells is a possible risk of this method, which can be avoided by the use of special bags for laparoscopic in-bag morcellation. We present a case of laparoscopic supracervical hysterectomy with in-bag morcellation in a uterus of more than 1400 g. and describe that this minimal-access surgery is safe and feasible even in very large uteri. This case report is registered in Research Registry under the UIN researchregistry1810.

Patient knowledge of hysterectomy and pap screening after minimally invasive hysterectomy

OBJECTIVE

To determine whether women know their own cervical cancer screening recommendations after hysterectomy, and to evaluate patients' understanding of hysterectomy terminology and cervical cancer screening.

METHODS

A 19-item questionnaire was developed and administered to 413 women who had undergone minimally invasive hysterectomy with benign pathology between January 2008 and January 2012.

RESULTS

A total of 190 women (46%) participated in the survey. The majority of respondents were Caucasian (61%) and had a college education (66%). Fifty-nine percent of respondents knew that a Pap test screens for cervical cancer, and 40% knew that HPV is related to cervical cancer. Eight-four percent understood that Pap screening is recommended if a woman still has a cervix after hysterectomy. Only 67% correctly identified if their cervix had been removed during their own surgery and if they needed future cervical cancer screening per current guidelines. Caucasian race and higher income were significant predictors of hysterectomy and screening knowledge.

CONCLUSION

Knowledge regarding Pap tests, HPV, and implications of a supracervical hysterectomy is lacking, even among a post-hysterectomy population.

PRACTICAL IMPLICATIONS

Patient educational information is needed to improve perioperative counseling regarding the type of hysterectomy performed and indications for future cervical cancer screening.

Laparoscopic supracervical hysterectomy for the larger uterus (>500 g): a case series and literature review

BACKGROUND

In clinical practice, the current trend for surgical hysterectomy for the large uterus is by laparotomy, where vaginal hysterectomy is not feasible. The benefits of a laparoscopic approach to hysterectomy are well documented, but limited literature is available on laparoscopic hysterectomy in the larger uterus. A supracervical hysterectomy should be considered for women, where there is no contraindication to a residual cervix.

OBJECTIVE

To compare surgical outcomes for laparoscopic supracervical hysterectomy (LSH) in the large uterus (equal or greater than 500 g) compared with normal (<500 g), results were compared to the limited literature on this topic.

METHODS AND STUDY DESIGN

A retrospective review was undertaken of 207 women who underwent an LSH between 2005 and 2015 at Whipps Cross University hospital. The operative outcome of patients undergoing surgery, for uteri both greater than 500 g and less than 500 g, was analysed. Data included patient demographics, intra-operative details, and complications. A literature search was performed using keywords 'laparoscopic supracervical hysterectomy' and 'laparoscopic sub-total hysterectomy' which yielded six informative articles.

RESULTS

In the study group of 207 patients, 67 had a large uterus (56 patients 500-1000 g, 11 patients >1000 g). The operation time and intra-operative blood loss were both greater in the larger uterus cohort (P < 0.0001 and P = 0.0021, respectively). The hospital stay and intra-operative complication rate were similar for the two study cohorts (six for the study, n = 207). Review of the literature revealed six relevant studies evaluating patients with uteri greater than 500 g. There was an agreement between all the studies that a larger uterus resulted in an increase in both intra-operative time and blood loss, but this did not translate to increase in hospital stay or intra-operative complications.

CONCLUSION

The use of LSH for the larger uterus is feasible and safe due to the low level of operative complications as demonstrated in our study and following a review of the literature.

Total laparoscopic hysterectomy: Analysis of the surgical learning curve in benign conditions

OBJECTIVE

To assess the learning curve for total laparoscopic hysterectomy.

METHODS

This study was a retrospective analysis of the learning curve for two surgeons during their first 257 consecutive cases of total laparoscopic hysterectomy at a teaching hospital. Patients were divided sequentially into groups comprising the first 75 patients, the next 75, and the final 107 patients. Age, body mass index, gestational parity, indications for laparoscopic hysterectomy, previous pelvic surgery, operating time, haemoglobin decline, complications, need for transfusion, and length of hospital stay were evaluated.

RESULTS

The mean operating time for total laparoscopic hysterectomy reduced significantly from 76.2 min to 68.9 min (p = 0.001) between the first and second 75-patient groups. Linear regression analysis showed a plateau was reached on the learning curve after 71-80 cases. The rate of all complications started at 8% in the first group of 75 patients, reduced to 6.7% in the next group, and decreased further in the final group to 4.7%. The decline was not statistically significant (p = 0.6). The difference in the need for transfusion was statistically significant between the first 75 patients and the second group of 75 (p = 0.04). Conversion from laparoscopy to laparotomy was required in five patients, four in the early group and one in the final group. Age, body mass index, parity, previous pelvic surgery, decline in haemoglobin, and length of hospital stay were similar among the three groups.

CONCLUSIONS

A plateau in the learning curve for TLH was reached after the first 75 cases. We can infer that there is a learning curve for TLH as confirmed by the decrease in operating time (accompanied by no change in complications) correlated to gain in experience. On the other hand, one should not disregard the fact that laparoscopy is not a complication-free surgery and achievement of the learning curve does not exclude complications. Gynaecological surgeons can perform TLH securely during the learning curve.

Indications and Route of Hysterectomy for Benign Diseases. Guideline of the DGGG, OEGGG and SGGG (S3 Level, AWMF Registry No. 015/070, April 2015)

Background: Official guideline "indications and methods of hysterectomy" to assign indications for the different methods published and coordinated by the German Society of Gynecology and Obstetrics (DGGG), the Austrian Society of Gynecology and Obstetrics (OEGGG) and the Swiss Society of Gynecology and Obstetrics (SGGG). Besides vaginal and abdominal hysterectomy, three additional techniques have been implemented due to the introduction of laparoscopy. Organ-sparing alternatives were also integrated. Methods: The guideline group consisted of 26 experts from Germany, Austria and Switzerland. Recommendations were developed using a structured consensus process and independent moderation. A systematic literature search and quality appraisal of benefits and harms of the therapeutic alternatives for symptomatic fibroids, dysfunctional bleeding and adenomyosis was done through MEDLINE up to 6/2014 focusing on systematic reviews and meta-analysis. Results: All types of hysterectomy led in studies to high rates of patient satisfaction. If possible, vaginal instead of abdominal hysterectomy should preferably be done. If a vaginal hysterectomy is not feasible, the possibility of a laparoscopic hysterectomy should be considered. An abdominal hysterectomy should only be done with a special indication. Organ-sparing interventions also led to high patient satisfaction rates, but contain the risk of symptom recurrence. Conclusion: As an aim, patients should be enabled to choose that therapeutic intervention for their benign disease of the uterus that convenes best to them and their personal life situation.

Urinary Tract Injury at Benign Gynecologic Surgery and the Role of Cystoscopy: A Systematic Review and Meta-analysis

OBJECTIVE

To calculate the rates of urinary tract injury detected during and after benign gynecologic surgery. To explore the role of routine intraoperative cystoscopy and determine if it helps in reducing injuries detected postoperatively.

DATA SOURCES

We conducted a literature search for urinary tract injuries at benign gynecologic surgery in PubMed, EMBASE, ClinicalTrials.gov, and Web of Science from January 2004 to August 2014. We combined our results with a database from a previously published systematic review to include earlier studies.

METHODS OF STUDY SELECTION

A total of 79 studies met our inclusion criteria. Excluded were letters to the editor, studies involving only selective cystoscopy in higher risk patients, case reports, and reports that included injuries resulting from obstetric or oncologic procedures.

TABULATION, INTEGRATION, AND RESULTS

Data from each report were classified according to type of surgery into vaginal hysterectomy, abdominal hysterectomy, laparoscopic hysterectomy, other (nonrobotic) gynecologic and urogynecologic surgery, robotic hysterectomy, and other robotic gynecologic and urogynecologic surgery. We determined the ureteric and bladder injury rates for each surgery type from studies in which routine intraoperative cystoscopy was performed and separately from studies in which it was not performed. Intraoperatively detected rates of ureteric and bladder injury were markedly higher with routine intraoperative cystoscopy. We obtained an adjusted ureteric injury rate of 0.3% and a bladder injury rate of 0.8%. The estimated postoperative ureteric injury detection rates per 1,000 surgeries were 1.6 without routine cystoscopy and 0.7 with routine cystoscopy. Postoperative bladder injury detection rates per 1,000 surgeries were 0.8 without routine cystoscopy and 1.0 with routine cystoscopy.

CONCLUSION

Although routine cystoscopy clearly increases the intraoperative detection rate of urinary tract injuries, this systematic review of 79 mostly retrospective studies shows that it does not appear to have much effect on the postoperative injury detection rate.

A Retrospective Analysis of the Impact of Myomectomy on Survival in Uterine Sarcoma

Laparoscopic myomectomy is a minimally invasive, conservative surgical approach commonly used for the treatment of uterine fibroids. However, there is a lack of effective means to distinguish the nature of uterine tumors prior to surgery. The impact of fibroid morcellation during laparoscopic surgery on the dissemination of cancerous uterine fibroids and long-term survival of patients has gained increasing attention. A retrospective cohort study was conducted to analyze the impact of different surgical approaches on recurrence-free survival (RFS) and overall survival (OS) in patients with a postoperative pathological diagnosis of uterine sarcoma at a single medical center. Patients who underwent the first surgery for uterine fibroids (confined to the uterus) and had a postoperative pathological diagnosis of uterine sarcoma were selected in the Chinese PLA General Hospital from January 2005 to January 2014. Based on the use of fibroid morcellation, the subjects were divided into fibroid morcellation (FM) and total hysterectomy (TH, non-morcellation) groups. Follow-up outcomes, including RFS and OS times, were observed. In total, 59 patients were included, with 30 cases in the FM group and 29 cases in the TH group. There were no significant differences in RFS and OS time between the two groups (RFS: P = 0.16, OS: P = 0.09). Multivariate correlation analysis showed that the impact of a higher grade level on RFS and OS was nearly 2-fold the impact of a lower grade level (RFS: P = 0.04, odds ratio (OR) = 1.97; OS: P = 0.03, OR = 2.29). Intraoperative morcellation, postoperative adjuvant therapy, age, tumor size, FIGO stage, and surgical approach were not risk factors affecting RFS and OS. Fibroid morcellation during laparoscopic surgery (including laparoscopic, transvaginal and transabdominal approaches) had no significant impact on RFS and OS time in patients. However, the 5-year RFS and OS rates were both lower in the FM group than in the TH group. Grade level was a significant risk factor for the prognosis of patients with uterine sarcoma.

Morcellation and the Incidence of Occult Uterine Malignancy: A Dual-Institution Review

Objectives

To determine the incidence of unsuspected uterine sarcoma (UtSarc), other uterine malignancies, and potential malignancies at the time of hysterectomy or myomectomy using power morcellation.

Methods

We performed a retrospective cohort study of all women undergoing myomectomy or hysterectomy using power morcellation at 2 institutions between January 1, 2004, and May 31, 2015. The primary outcome was the incidence of uterine malignancy (UM). The predefined secondary outcome was the occurrence of other conditions associated with malignant behavior. For analysis, any UtSarc or endometrial cancer was categorized as a “uterine malignancy,” whereas other pathologies with cytologic atypia were categorized as “uterine premalignant disease” (UPM). All other pathological results were classified as “nonmalignant.”

Results

A total of 1004 women underwent hysterectomy or myomectomy using power morcellation during the studied period. Two women (1/502; 95% confidence interval [CI], 1/4144-1/139) were found to have UM pathology, 2 endometrial carcinomas and none with UtSarc (97.5% CI, 0-1/273). Six (1/167; 95% CI, 1/455-1/77) women were found to have UPM on final pathology: 2 atypical leiomyomas, 1 STUMP (smooth muscle tumors of uncertain malignant potential), and 3 endometrial atypical hyperplasias. Women with UM had uteri that weighed more than those with NM pathology (840 g vs 217.7 g, P = 0.028), and this trend was also seen with UM and UPM (435.0 g vs 217.2 g, P = 0.081). Women with UM and UPM were more likely to have a preoperative surgical indication of “uterine leiomyoma” compared with other benign etiologies (P < 0.001).

Conclusions

Among this cohort, all cases of unsuspected UM at the time of myomectomy or hysterectomy using power morcellation were found to be endometrial carcinoma. Unsuspected UM pathology had an incidence of 1 of 502. Factors associated with increased likelihood of UM or UPM were greater uterine weight and leiomyoma as the surgical indication.

Case-Mix Variables and Predictors for Outcomes of Laparoscopic Hysterectomy: A Systematic Review

The assessment of surgical quality is complex, and an adequate case-mix correction is missing in currently applied quality indicators. The purpose of this study is to give an overview of all studies mentioning statistically significant associations between patient characteristics and surgical outcomes for laparoscopic hysterectomy (LH). Additionally, we identified a set of potential case-mix characteristics for LH. This systematic review was conducted according to the Meta-Analysis of Observational Studies in Epidemiology guidelines. We searched PubMed and EMBASE from January 1, 2000 to August 1, 2015. All articles describing statistically significant associations between patient characteristics and adverse outcomes of LH for benign indications were included. Primary outcomes were blood loss, operative time, conversion, and complications. The methodologic quality of the included studies was assessed using the Newcastle-Ottawa Quality Assessment Scale. The included articles were summed per predictor and surgical outcome. Three sets of case-mix characteristics were determined, stratified by different levels of evidence. Eighty-five of 1549 identified studies were considered eligible. Uterine weight and body mass index (BMI) were the most mentioned predictors (described, respectively, 83 and 45 times) in high quality studies. For longer operative time and higher blood loss, uterine weight ≥ 250 to 300 g and ≥500 g and BMI ≥ 30 kg/m(2) dominated as predictors. Previous operations, adhesions, and higher age were also considered as predictors for longer operative time. For complications and conversions, the patient characteristics varied widely, and uterine weight, BMI, previous operations, adhesions, and age predominated. Studies of high methodologic quality indicated uterine weight and BMI as relevant case-mix characteristics for all surgical outcomes. For future development of quality indicators of LH and to compare surgical outcomes adequately, a case-mix correction is suggested for at least uterine weight and BMI. A potential case-mix correction for adhesions and previous operations can be considered. For both surgeons and patients it is valuable to be aware of potential factors predicting adverse outcomes and to anticipate this. Finally, to benchmark clinical outcomes at an international level, it is of the utmost importance to introduce uniform outcome definitions.

Safely Increase the Minimally Invasive Hysterectomy Rate: A Novel Three-Tiered Preoperative Categorization System Can Predict the Difficulty for Benign Disease

CONTEXT

A nonlaparotomic route is recommended for hysterectomy for benign indications.

OBJECTIVE

1) Predict the difficulty of hysterectomy to treat benign disease as measured by operative time and risk of laparotomy, 2) confirm the safety and quality of increasing our minimally invasive hysterectomy (MIH) rate, and 3) determine whether the assistant's experience affected the likelihood of an MIH being performed in equally difficult hysterectomies.

DESIGN

All hysterectomies for benign disease performed at the Kaiser Permanente Fontana Medical Center in Fontana, CA, in 2012 were reviewed for length of surgery, length of stay, complications, and readmissions. A three-tiered category system was developed from four preoperative parameters (body mass index, number of vaginal deliveries, clinical uterine size, and history of major abdominal surgery) to anticipate length and difficulty of surgery.

MAIN OUTCOME MEASURES

Rates of MIH, complications, and readmissions as well as length of surgery and length of stay for similarly difficult hysterectomies. These outcomes were compared with surgeons' and assistants' experience.

RESULTS

Of 576 hysterectomies performed for benign disease, 89% were MIH with a 3% complication rate and 4% readmission rate. An increase in the hysterectomy category was statistically significantly associated with longer surgery times and a higher percentage of laparotomy. With the most experienced assistants, the MIH rate was 98%.

CONCLUSIONS

Using 4 preoperative parameters, the average operating time for hysterectomy for benign disease can be predicted. A higher hysterectomy category predicts a more difficult surgery. Our center has increased its MIH rate to 89% while maintaining safety.

Malignancy rate of 10,731 uteri morcellated during laparoscopic supracervical hysterectomy (LASH)

Purpose

This study aims to evaluate the number of cases of occult uterine malignancies in all LASH surgeries at the MIC clinic (Berlin) and to verify how the operative technique affects the prognosis of the disease.

Methods

Data of 10,731 patients who underwent a standardized LASH surgery with electric power morcellation between 1998 and April 30, 2014 were retrospectively analyzed. Main indication for LASH was symptomatic uterine myomas (81.3 %).

Results

No intra-operative complication was caused by use of a morcellator. In total, six sarcomas (0.06 %), including four endometrial stromal sarcomas (0.04 %) two leiomyosarcomas (0.02 %), and eight endometrial cancers (0.07 %) were documented. This amounts to a very low uterine malignancy rate of 0.13 %. Median follow-up period for all six patients with sarcoma and seven patients with endometrial cancer was 65.58 months (13–169). No recurrence was reported for the patients with endometrial cancer and five sarcoma patients in the comprehensible follow-up period. One patient died 13 months after LASH surgery due to the diagnosed leiomyosarcoma with peritoneal carcinomatosis and bone metastases.

Conclusion

In 10,731 morcellated uteri during LASH only 0.06 % sarcoma and 0.07 % endometrial carcinoma were detected. All patients should be informed about the rare possibility of a malignant disease during pre-operative counseling. With a timely follow-up surgery according to the oncologic guidelines, our data suggest a very good prognosis in terms of survival after LASH with morcellation of malignant tumors in the uterus.

Age-stratified risk of unexpected uterine sarcoma following surgery for presumed benign leiomyoma

BACKGROUND

Estimates of unexpected uterine sarcoma following surgery for presumed benign leiomyoma that use age-stratification are lacking.

PATIENTS AND METHODS

A retrospective cohort of 2,075 patients that had undergone myomectomy was evaluated to determine the case incidence of unexpected uterine sarcoma. An aggregate risk estimate was generated using a meta-analysis of similar studies plus our data. Database-derived age distributions of the incidence rates of uterine sarcoma and uterine leiomyoma surgery were used to stratify risk by age.

RESULTS

Of 2,075 patients in our retrospective cohort, 6 were diagnosed with uterine sarcoma. Our meta-analysis revealed 8 studies from 1980 to 2014. Combined with our study, 18 cases of leiomyosarcoma are reported in 10,120 patients, for an aggregate risk of 1.78 per 1,000 (95% confidence interval [CI]: 1.1-2.8) or 1 in 562. Eight cases of other uterine sarcomas were reported in 6,889 patients, for an aggregate risk of 1.16 per 1,000 (95% CI: 0.5-4.9) or 1 in 861. The summation of these risks gives an overall risk of uterine sarcoma of 2.94 per 1,000 (95% CI: 1.8-4.1) or 1 in 340. After stratification by age, we predict the risk of uterine sarcoma to range from a peak of 10.1 cases per 1,000, or 1 in 98, for patients aged 75-79 years to <1 case per 500 for patients aged <30 years.

CONCLUSION

The risk of unexpected uterine sarcoma varies significantly across age groups. Our age-stratified predictive model should be incorporated to more accurately counsel patients and to assist in providing guidelines for the surgical technique for leiomyoma.

Laparoscopic Hysterectomies: Our 10 Years Experience in a Single Laparoscopic Center

STUDY OBJECTIVE

To evaluate the association between outcomes of laparoscopic hysterectomy with respect to clinical factors, intraoperative variants, and post-operative complications.

DESIGN

The study conducted was retrospective (Canadian Task Force Classification II-1).

SETTING

The set used in this study was a gynecological laparoscopic centre.

PATIENTS

The present study included 858 women who underwent laparoscopic hysterectomies with or without bilateral/unilateral salpingo-oophorectomy, from December 2004 to May 2014.

INTERVENTIONS

Eight hundred and sixteen patients underwent total laparoscopic hysterectomy, 14 patients underwent subtotal laparoscopic hysterectomy, 20 patients underwent laparoscopic-assisted vaginal hysterectomy, and 8 patients underwent laparoscopic radical hysterectomy with bilateral pelvic lymph node dissection.

MEASUREMENTS AND MAIN RESULTS

All surgeries were performed by the same surgeon, using the same surgical technique. The medical records were reviewed, and data were collected with respect to age, indications, type of surgery performed, intraoperative variants, and post-operative complications. Patient average age was 44.9 ± 6.2 years. Most common indication for benign TLH was leiomyoma of 54.4 %. Indications for laparoscopic radical hysterectomy were early stage endometrial cancer (n = 5) and early stage cervical cancer (n = 3). The maximum uterine size operated on was from 20-26 weeks, 4.9 % (n = 42). 9.7 % had previous abdominopelvic surgery. Fifty three % underwent unilateral/bilateral salpingo-oophorectomy. Conversion rate was 0.93 % (n = 8). The minimum and maximum operating time during the total study period was 20 min-2 h. The major complication rates were 0.9 % (n = 8). The hospital stay was not more than 2 days.

CONCLUSION

In our experience of 858 laparoscopic hysterectomies, 850 were done for benign indications, and 8 done for malignancies. TLH can be performed more safely and under vision, with less blood loss, early post-operative recovery, less post-operative infection, and less complication rate.

Cervical Detachment Using Monopolar SupraLoop™ Electrode versus Monopolar Needle in Laparoscopic Supracervical Hysterectomy (LSH): An Interventional, Comparative Cohort Study

Objective: Currently available monopolar loop electrodes are difficult to handle in laparoscopic supracervical hysterectomy (LSH) and are entirely disposable devices, generating additional operating costs. The aim of this interventional study was the comparison of the efficiency and safety of cervical detachment with a newly developed monopolar loop electrode (SupraLoop™) with a conventional method of cervical detachment in LSH. Material and Methods: Our study sample included 1598 patients; 1070 patients that underwent LSH with cervical detachment using the monopolar SupraLoop™ (study group) and 528 patients that underwent LSH with cervical detachment using the monopolar needle (control group). We also assessed cervical detachment time and total device application and cutting time in a subgroup of 49 patients (23 patients from the study group and 26 patients from the control group). Results: Total operation time for LSH was significantly shorter among SupraLoop™ patients (93 ± 41 minutes) when compared to patients in whom cervical detachment was performed with the needle (105 ± 44 minutes) (p < 0.001). Cervical detachment time and total device application including cutting time was significantly shorter for the SupraLoop™ group (SupraLoop vs. needle; 0.12 ± 0.21 min vs. 5.1 ± 4.4 min [p < 0.001]; 2.3 ± 1.8 min vs. 5.4 ± 2.4 min [p < 0.001]). There were no major or minor complications directly related to the use of the SupraLoop™ device, whereas two intraoperative complications were directly related to the application of the monopolar needle. Conclusion: The newly developed monopolar loop electrode (SupraLoop™) is both an effective and safe instrument for cervical detachment in laparoscopic supracervical hysterectomy, and performed better than the needle, offering a significantly shorter operating time and less complications for the hysterectomy compared to the conventional method.

Postoperative patient satisfaction after laparoscopic supracervical hysterectomy

This study demonstrates a high degree of postoperative patient satisfaction after laparoscopic supracervical hysterectomy.

Background and Objectives:

The aim of this study was to evaluate postoperative patient satisfaction in women after laparoscopic supracervical hysterectomy (LASH).

Methods:

A retrospective study by a mailed questionnaire among 2334 women who underwent hysterectomy via LASH at the MIC-Klinik, Berlin, between 1998 and 2004 was conducted. Indications for LASH were uterus myomatosus, adenomyosis uteri, disorders of bleeding, and genital descensus. The LASH operation technique was standardized and remained consistent throughout the observation period. Pearson's test for metric variables, Spearman's rank correlation test for ordinal data, Mann-Whitney U test, and Kruskal-Wallis test were used.

Results:

Of the 2334 questionnaires mailed, 1553 were returned and 1431 (61.3%) of those could be analyzed. Almost 94% (93.9%) of the women were highly satisfied with the outcome, 5.6% reported medium satisfaction, and 0.5% were not satisfied. There was no significant difference in patient satisfaction with regard to the different indication for LASH.

Conclusion:

This study demonstrates high postoperative patient satisfaction after LASH. The rate of highly satisfied women might be increased by carefully choosing the right indications for LASH and improving operation techniques. This is important for widening acceptance of this innovative new operation standard.

Laparoscopic supracervical hysterectomy (LSH) versus total laparoscopic hysterectomy (TLH): an implementation study in 1,952 patients with an analysis of risk factors for conversion to laparotomy and complications, and of procedure-specific re-operations

PURPOSE

To compare laparoscopic supracervical hysterectomy (LSH) with total laparoscopic hysterectomy (TLH) with regard to relevant surgical parameters and risk factors of conversion to laparotomy and complications.

METHODS

This prospective, open, single-center, interventional study included women with benign gynecologic disease who underwent standardized LSH or TLH. The techniques were compared for conversion rate and mean operating time, hemoglobin drop, hospital stay, and complication rates using descriptive statistics and standard non-parametric statistical tests. Risk factors of conversion and complications were identified by logistic regression analysis.

RESULTS

During January 2003 to December 2010, 1,952 women [mean age (SD): 47.5 (7.2) years] underwent LSH [1,658 (84.9%)] or TLH [294 (15.1%)], mostly (>70%) for uterine fibroids. Significant differences in surgical parameters were observed for conversion rate (LSH/TLH: 2.6/6.5%), mean operating time [87 (34)/103 (36) min], hemoglobin drop [1.3 (0.8)/1.6 (1.0) g/dL], and hospital stay [4.3 (1.5)/4.9 (2.8) days]. Overall intraoperative (0.2/0.7%) and long-term (>6 weeks) post-operative (0.8/1.7%) complication rates did not differ significantly, but the short-term LSH complication rate was significantly lower (0.6 vs. 4.8%). Spotting (LSH, 0.2%) and vaginal cuff dehiscence (TLH, 0.7%) were long-term method-specific complications. Logistic regression showed that uterine weight and extensive adhesiolysis were significant factors for conversion while previous surgery, age, and BMI were not. Major risk factors of short-term complications were age, procedure (LSH/TLH), and extensive adhesions.

CONCLUSIONS

Both procedures proved effective and were well tolerated. LSH performed better than TLH regarding most outcome measures. LSH is associated with very low rates of re-operation and spotting.

A randomized trial of day-case vs inpatient laparoscopic supracervical hysterectomy

OBJECTIVE

To determine whether women having day-case laparoscopic supracervical hysterectomy are more or less satisfied with the length of hospital stay compared with women who stayed overnight after the procedure.

STUDY DESIGN

An randomized control trial of 49 women randomized to day-case or overnight hospital stay after laparoscopic supracervical hysterectomy. Satisfaction with length of hospitalization and quality of life were compared using the Mann-Whitney U test.

RESULTS

No group differences were found in satisfaction with length of hospital stay (P = .13). There was a nonsignificant trend toward greater anxiety in the day-case group (P = .06 on day 1 postoperative). Quality of life was lower in the day-case group on days 2 (P = .02) and 4 (P = .03), postoperatively.

CONCLUSION

Women having a day-case hysterectomy were discharged after median of 5 hours postoperative and were similarly satisfied as women hospitalized overnight. Quality of life, however, does appear to be compromised by day-case surgery.

Laparoscopically assisted vaginal hysterectomy: a novel method

This paper describes a novel method of facilitating laparoscopically assisted vaginal hysterectomy (LAVH) uniquely distinguished by commencing vaginally and finishing laparoscopically. For this technique a specially designed uterine manipulator has been developed.

Hysterectomy-a comparison of approaches

BACKGROUND

The advantages and disadvantages of the various surgical techniques for hysterectomy are currently a topic of debate, with particular controversy over leaving the cervix in situ in the laparoscopic supracervical hysterectomy (LASH) procedure.

METHODS

In a retrospective single-center study, medical history and clinical characteristics were compared in patients who had undergone hysterectomy for benign disease in the period 2002-2008 at the Department of Obstetrics and Gynecology, Erlangen University Hospital. Postoperative satisfaction and the frequency of secondary operations for prolapse or incontinence in women with surgery between 2002 and 2007 were surveyed by means of a questionnaire.

RESULTS

The longest hospital stay was observed after abdominal hysterectomy (AH; 10 days), followed by vaginal hysterectomy (VH; 7.8 days) and laparoscopy-assisted vaginal hysterectomy (LAVH; 7.2 days). The shortest stays in hospital were seen after LASH (5.9 days) and total laparoscopic hysterectomy (TLH; 5.7 days). The shortest operating time was noted with VH (87 min) and the longest with LAVH (122 min). The lowest rates of blood loss were with LASH (1.38 g/dL) and TLH (1.51 g/dL). The highest rate of postoperative complications occurred after AH (8.9%). No differences were found in relation to postoperative satisfaction or surgery for prolapse or incontinence.

CONCLUSION

No postoperative benefits were found for leaving the cervix in situ when performing LASH. However, this was not a controlled randomized study.
