Laparoscopic Access with Optical Gasless Trocar: A Single-center Experience of 7431 Procedures.

STUDY OBJECTIVE: To analyze the complications experienced and describe laparoscopic surgery using a gasless optical trocar. DESIGN: A retrospective study. SETTING: A department of obstetrics and gynecology in a tertiary center in Italy. PATIENTS: Seven thousand four hundred thirty-one surgical procedures were performed. INTERVENTIONS: From the hospital database, data were evaluated regarding major complications of laparoscopy with the ENDOPATH XCEL Bladeless Trocar (Ethicon, Johnson & Johnson, Somerville, NJ) performed between 2000 and 2017 by different laparoscopic surgeons. MEASUREMENTS AND MAIN RESULTS: The mean age of the patients was 40.66 ± 12.06 years (range, 13-91 years). The mean body mass index was 22.12 ± 3.64 kg/m2 (range, 15.74-41.51 kg/m2). The overall complication rate was 0.31% (23/7431 cases). Major complications included stomach perforation in 1 procedure (0.014%), ileal perforation in 2 procedures (0.028%), and blood vessel perforation in 1 procedure (0.014%). Twelve procedures were completed with initial access through the omentum and 2 through an ovarian cyst. In 5 procedures (0.067%), conversion to laparotomy was required because the optical trocar failed to reach the abdominal cavity. With regard to complications requiring further intervention (n = 9), the rate of complications was 0.12%. CONCLUSIONS: The optical gasless trocar is a feasible laparoscopic entry technique. The complication rate is lower than those reported previously.

Sexual Function following Laparoscopic versus Transvaginal Closure of the Vaginal Vault after Laparoscopic Hysterectomy: Secondary Analysis of a Randomized Trial by the Italian Society of Gynecological Endoscopy Using a Validated Questionnaire.

STUDY OBJECTIVE: The effect of the different types of vaginal cuff closures on posthysterectomy sexual function has not been investigated in depth. We evaluated if there is a difference between transvaginal versus a laparoscopic closure after total laparoscopic hysterectomy (TLH) on female sexual function, using a validated questionnaire. DESIGN: Secondary analysis of a prospective randomized controlled trial. SETTING: Three academic research centers. PATIENTS: Women consenting to telephone interviews on their sexual life before and after undergoing TLH were included. INTERVENTIONS: Patients were randomly assigned to a laparoscopic or transvaginal approach for vaginal cuff closure at the end of TLH for benign indications. MEASUREMENTS AND MAIN RESULTS: A validated questionnaire (the Female Sexual Function Index [FSFI]) was used to explore sexuality before and after the operation. Of the 1408 patients enrolled in the primary study, 400 patients were asked to complete the questionnaire. Of them, 182 (41.4%) were eligible and accepted enrollment in the present analysis. No difference was found in terms of pre- and postoperative FSFI scores between groups. Patients with a low preoperative FSFI score (<26.55) had a significantly higher likelihood of having a postoperative sexual disorder (p <.001). Women who received bilateral adnexectomy before menopause and those with postoperative vaginal cuff hematoma had a significantly lower postoperative FSFI score (p = .001 and p = .04, respectively). After multivariable analysis, both variables maintained at least a tendency toward an association with a lower postoperative FSFI score (odds ratio, 2.696; 95% confidence interval, 1.010-7.194; p = 0.048 and p = 0.053; odds ratio, 13.2; 95% confidence interval, .966-180.5, respectively). CONCLUSION: Transvaginal and laparoscopic cuff closures after TLH have similar sexual postoperative outcomes. A patient with sexual problems before TLH is more likely to have a low FSFI score postoperatively. Premenopausal patients undergoing bilateral ovariectomy and those with postoperative vaginal cuff hematoma have a worse postoperative sexual life.

Laparoscopic management of a large urethral leiomyoma.

INTRODUCTION AND HYPOTHESIS: A 42-year-old female presented with a 12-cm mass bulging the anterior vaginal wall and causing urgency urinary incontinence and bulk symptoms. METHODS: Imaging showed a tumor originating from the dorsal and cranial part of the urethra and developing in the vesicouterine space and vesicovaginal septum, dislocating the bladder ventrally and the uterus cranial-dorsally. RESULTS: Tranvaginal biopsy showed a benign leiomyoma. A laparoscopic approach with development of the vesicouterine space permitted a safe partial morcellation of the myoma. After the bladder and vaginal wall had been completely freed, further caudal dissection was conducted with isolation of the distal cranio-dorsal portion of the urethra. The dissection plane with the vaginal wall was developed up to the caudal margin of the urethral myoma almost corresponding to the vulvar plane, and total excision of the lesion was performed. CONCLUSION: Laparoscopic management of urethral leiomyomas that develop into the vesicouterine space and vesicovaginal septum is feasible and safe also for very large lesions.

Laparoscopic vs transvaginal cuff closure after total laparoscopic hysterectomy: a randomized trial by the Italian Society of Gynecologic Endoscopy.

BACKGROUND: Vaginal cuff dehiscence following hysterectomy is considered an infrequent but potentially devastating complication. Different possible techniques for cuff closure have been proposed to reduce this threatening adverse event. OBJECTIVE: The aim of the present randomized study was to compare laparoscopic and transvaginal suture of the vaginal vault at the end of a total laparoscopic hysterectomy, in terms of incidence of vaginal dehiscence and vaginal cuff complications. Factors associated with vaginal dehiscence were also analyzed. This article presents the results of the interim analysis of the trial. STUDY DESIGN: Patients undergoing total laparoscopic hysterectomy for benign indications were randomized at the time of colpotomy to receive vaginal closure through transvaginal vs laparoscopic approach using a 1:1 ratio. Allocation concealment was obtained using a password-protected randomization database. Monopolar energy for colpotomy was set at 60W. Vaginal closure was performed with a single-layer running braided and coated 0-polyglactin suture. In all cases an attempt was performed to include the posterior peritoneum in the suture. Laparoscopic knots were tied intracorporeally. All patients were scheduled for a postoperative follow-up visit 3 months after surgery, to detect possible vaginal cuff complications. Univariate and multivariable analyses were performed to identify independent predictors of vaginal cuff dehiscence after total laparoscopic hysterectomy. RESULTS: After enrollment of 1408 patients, a prespecified interim analysis was conducted. Thirteen (0.9%) women did not undergo the postoperative assessment and were excluded. Baseline characteristics of the 1395 patients included (695 in the transvaginal group and 700 in the laparoscopic group) were similar between groups. Patients in the transvaginal group had a significantly higher incidence of vaginal dehiscence (2.7% vs 1%; odds ratio, 2.78; 95% confidence interval, 1.16-6.63; P = .01) and of any cuff complication (9.8% vs 4.7%; odds ratio, 2.19; 95% confidence interval, 1.43-3.37; P = .0003). Based on these findings, the data monitoring committee recommended that the trial be terminated early. After multivariable analysis, transvaginal closure of the vault was independently associated with a higher incidence of vaginal dehiscence and any vaginal complication; premenopausal status and smoking habit were independently associated with a higher risk of dehiscence. CONCLUSION: Laparoscopic closure of the vaginal cuff at the end of total laparoscopic hysterectomy is associated with a significant reduction of vaginal dehiscence, any cuff complication, vaginal bleeding, vaginal cuff hematoma, postoperative infection, need for vaginal resuture, and reintervention.

The Rare Extragonadal Omental Teratoma: A Case Report.

Teratomas of extragonadal origin are extremely rare, and the most common extragonadal site to find teratomas is the omentum. Teratomas are typically found in women of reproductive age, but they are also seen in young girls and postmenopausal women. Generally, teratomas arise from germ cells that may induce different cells to originate from the 3 primitive embryonic layers. Three main theories have been proposed to explain their location. The present report summarizes these theories as well as describes a case of a mature cystic teratoma of the omentum that was managed by laparoscopic resection.

Long-term therapy with dienogest or other oral cyclic estrogen-progestogen can reduce the need for ovarian endometrioma surgery.

BACKGROUND: Almost 10% of women in reproductive age are diagnosed with ovarian endometriomas and can experience symptoms and infertility disorders. Ovarian endometriomas can be treated with medical or surgical therapy. OBJECTIVE: To assess whether long-term therapy with dienogest or oral cyclic estrogen-progestogens is effective in reducing the size of ovarian endometriomas, alleviating associated symptoms, and reducing the requirement for surgery. DESIGN: Prospective non-interventional cohort study. METHODS: We enrolled childbearing women diagnosed with ovarian endometriomas. We collected demographic, clinical, and surgical data, including the evaluation of ovarian endometrioma-associated symptoms and pain using the visual analog scale. We grouped the women according to treatment regimen into dienogest, estrogen-progestogens, and no-treatment. Patient's assessment was performed at baseline and after 12 months evaluating the largest ovarian endometrioma diameter (in millimeters) and the associated symptoms. Furthermore, we analyzed the impact of hormonal treatment in a sub-group of women fulfilling at baseline the criteria for a first-line surgical approach (ovarian endometrioma > 30 mm with visual analog scale > 8 or ovarian endometrioma > 40 mm before assisted reproductive treatments or any ovarian endometrioma(s) > 60 mm). RESULTS: We enrolled 142 patients: 62, 38, and 42 in dienogest, estrogen-progestogens, and no-treatment groups, respectively. No significant differences were found regarding baseline characteristics. After 12 months, the mean largest ovarian endometrioma diameter increased in the no-treatment group (31.1 versus 33.8; p < 0.01), while a significant reduction was registered in the dienogest (35.1 versus 25.8; p < 0.01) and estrogen-progestogens (28.4 versus 16.7; p < 0.01) groups; no significant difference in ovarian endometrioma diameter reduction between these two latter groups was noted (p = 0.18). Ovarian endometrioma-associated symptoms and pain improved in dienogest and estrogen-progestogens groups, with a significantly greater effect for dienogest than for estrogen-progestogens for dysmenorrhea (74% versus 59%; p < 0.01). In the sub-group of women eligible for first-line surgery at baseline, long-term treatment with dienogest and estrogen-progestogens reduced surgical eligibility by 30%. CONCLUSIONS: Decreased mean largest ovarian endometriomas'diameter after 12 months and reduction of the need for surgical treatment by 30% were observed in dienogest and estrogen-progestogens groups. Long-term treatment with dienogest had a greater effect in alleviating dysmenorrhea and pain.

Diagnosis, Treatment and Prognosis of Mesonephric Adenocarcinoma of the Vagina: A Literature Review and a Case Report.

BACKGROUND: Mesonephric adenocarcinoma (MA) of the vagina is a rare tumor that arises from mesonephric remnants (Wolffian) in the female genital tract. It is a neoplasm with no significant evidence about its diagnosis, treatment, follow-up and prognosis. METHODS: Systematic research of the literature was conducted in Scopus, PubMed/MEDLINE, ScienceDirect and the Cochrane Library, including observational prospective and retrospective studies, case series and case reports. We collected data regarding studies related to diagnosis and treatment options evaluating the following aspects: study design, population, treatment type, rate of surgical complications and fertility outcome. We further included a case report of laparoscopic management of MA with pictorial assays. RESULTS: Thirteen cases of MA of the vagina are available in the literature, including our case report. The median age at diagnosis was 52 years old; the majority of patients reported vaginal bleeding as a symptom (38%); and ultrasound, followed by a magnetic resonance and CT scan were the diagnostic tools most used. In 54% of the cases, a surgical biopsy was performed, and 92% of the patients underwent upfront surgery with an open access or vaginal resection except one case fully managed by minimally invasive surgery. Most of the patients (68%) received adjuvant treatment with chemotherapy or radiotherapy or a combination of them. The mean follow-up period was 6 years. CONCLUSIONS: Despite the rarity of this cancer and bizarre location, a minimally invasive approach seems feasible after multidisciplinary evaluation. According to the rarity of this tumor, any future case and follow-up data must be reported in the literature in order to enlarge the knowledge about it.

Prevaccination distribution of human papillomavirus types in Italian women with high-risk lesions and cervical neoplasia.

OBJECTIVES: The aim of this study was to determine both human papillomavirus (HPV) prevalence and type distribution in cervical specimens of women with cytological abnormalities and to establish the association with high-grade lesions and cervical neoplasia in order to estimate the impact of an HPV vaccine in this region. METHODS: Four hundred and ninety-three cervical specimens obtained from women undergoing routine cervical screening by liquid-based Pap smear were analyzed by Roche linear array HPV genotyping to identify HPV genotypes. RESULTS: HPV 16 was the genotype detected most frequently, followed by HPV 31, 33 and 52. Multiple infections were frequent (58.5%), but decreased with the increase of cervical severity. We found multiple infections composed by only LR types in 4 women: 3 had a histological diagnosis of cervical intraepithelial neoplasia (CIN) 3 and 1 a diagnosis of cervical cancer. HPV 16 alone was present in 24.6% of CIN 3 lesions and 40% of neoplasia. However, in our region, there are an additional 28% of cases of carcinoma in situ and 40% of cases of invasive cancer due to different HPV types that should be considered for eventual inclusion in second-generation HPV vaccines. CONCLUSIONS: These results highlight the importance of assessing individual types in the management and prediction of outcome of women with abnormal baseline cytology and may contribute to determine the potential efficacy of an HPV vaccine in clinical practice.

Adnexal torsion in late pregnancy.

We report a case of adnexal torsion in a singleton pregnancy at 27 weeks of gestation. Adnexal torsion during pregnancy is a rare condition, and it is quite exceptional during the third trimester. The symptoms are non-specific and can be confused with other acute abdominal disorders. In our case, ultrasound allowed an accurate preoperative diagnosis.

A new laparoscopic-transvaginal technique for rectosigmoid resection in patients with endometriosis.

OBJECTIVE: To present our experience with a new technique for laparoscopic rectosigmoid resection in patients with endometriosis. DESIGN: Prospective collaborative cohort study. SETTING: Gynecologic departments of two university hospitals. PATIENT(S): Thirty-three women with rectosigmoid endometriotic lesions requiring segmental bowel resection. INTERVENTION(S): Laparoscopic intracorporeal division of the distal bowel and exteriorization of the affected segment via a colpotomy incision to complete the resection. MAIN OUTCOME MEASURE(S): Intraoperative and postoperative complications, and relief from symptoms. RESULT(S): The only intraoperative complication was bleeding from the inferior mesenteric artery that required conversion to laparotomy to obtain hemostasis. No patient required a temporary colostomy. No anastomotic complications were identified. Postoperative complications included a symptomatic pelvic seroma that required operative drainage in 1 patient and urinary retention that required intermittent self-catheterization in 3 women. The median follow-up duration was 13 months (range, 3-27 mo). Twenty-seven women were symptom free at the time of last follow-up evaluation. No patient had recurrent cyclic rectal bleeding, rectal pain on defecation, or tenesmus. Postoperatively, 4 of 13 patients who tried to conceive were successful. CONCLUSION(S): Segmental colorectal resection with a combined laparoscopic-transvaginal approach, avoiding the extension of port-site incisions, represents a viable option for the treatment of bowel endometriosis.

A comparison of urinary complications following total laparoscopic radical hysterectomy and laparoscopic pelvic lymphadenectomy to open abdominal surgery.

OBJECTIVE: The objective of this study was to compare total laparoscopic radical hysterectomy (TLRH) and laparoscopic pelvic lymphadenectomy (LPS) to total abdominal radical hysterectomy (TARH) and pelvic lymphadenectomy (LPT) in terms of urinary tract lesions and postoperative urinary retention. METHODS: Starting in 2004, we treated all early stage cervical cancer patients with TLRH and LPS. The control group for this analysis was a historical cohort of patients treated with TARH+LPT. Within the TLRH+LPS group, we assessed whether the width of parametrial tissue removed was a risk factor for urinary tract injuries or postoperative urinary retention. RESULTS: Fifty women were included in the TLRH+LPS group and forty-eight were included in the TARH+LPT group. There were no conversions from laparoscopy to laparotomy. There was no statistically significant difference in intraoperative urinary complications between the groups. Four (8%) intraoperative urinary tract injuries in the LPS (3 cystotomies and 1 ureteral lesions all repaired laparoscopically) and 2 (4.2%) in the LPT group (2 cystotomies) occurred (p=0.68). Similarly, there was no statistically significant difference in postoperative urinary complications between groups. Urinary postoperative complications were: 1 (2%) ureterovaginal and 1 vesicovaginal fistulas, 1 delayed ureteric fistula in LPS group vs. 0 in LPT group (p=0.24). Urinary retention was complained by 7 (14%) and 7 (14.6%) patients in LPS and LPT groups respectively (p=1.00). The average width of parametrial tissue removed in the LPS group was 32.2+14.0 mm in patients with vs. 39.5+13.6 mm in patients without urinary complications (p=0.11). CONCLUSIONS: A laparoscopic approach is comparable to the laparotomy in terms of urinary lesions and postoperative retention. The width of parametrium removed does not affect the risk of urinary lesions or postoperative retention.

Surgicopathologic outcome of laparoscopic versus open radical hysterectomy.

OBJECTIVE: To compare the surgicopathologic outcome of total laparoscopic radical hysterectomy (LRH) with that of abdominal radical hysterectomy (ARH) for the treatment of early-stage cervical cancer. METHODS: Radical hysterectomy specimens of sequential patients undergoing LRH (N=50) were compared with those of historical controls selected from consecutive women who have had conventional ARH (N=48), and who met the same criteria for eligibility as the cases. To evaluate the extent of parametrial resection, parametrial tissues were systematically measured at their widest dimensions before tissue processing. RESULTS: No difference was found in demographics, histologic type, tumor stage and grade between the two groups. The parametrial width was similar between LRH and ARH in both type II (right parametrium: 2.4 cm (1-3) vs. 2.3 (1.8-4.0), p=0.28; left parametrium: 2.3 cm (1.8-4) vs. 2.2 (1.2-3.0), p=0.54) and type III radical hysterectomy (right parametrium: 3.8 cm (2.3-6.5) vs. 3.4 (1.7-7.0), p=0.59; left parametrium: 3.6 cm (2-6) vs. 3.5 (1.5-6.5), p=0.82). There were no significant differences between the two groups with regard to lymph nodes yield and likelihood of identifying positive margins or metastatic disease. CONCLUSION: Our results suggest that laparoscopically managed patients with cervical cancer undergo a similar extent of surgery as those treated with the traditional ARH, as judged by objective pathologic criteria.
