RESUMO

OBJECTIVE: Vaginal natural orifice transluminal endoscopic surgery (vNOTES) is an emerging surgical procedure that combines the advantages of the vaginal approach with laparoscopic vision and instrumentation. Shorter hospitalization and lesser postoperative pain associated with vNOTES may be explained by the advantages of this innovative surgical approach (e.g., absence of abdominal incisions, shorter operative time, and lower insufflation pressure). Ovarian tissue cryopreservation allows to preserve reproductive and endocrine functions in young women with oncological disease at risk of premature ovarian insufficiency (POI) caused by gonadotoxic treatments. Ovarian tissue biopsy for cryopreservation consists of a large biopsy of 1 or both ovaries that is usually performed by laparoscopy. Then, the removed ovarian tissue is cryopreserved for the future transplant after cancer remission. The volume of ovarian biopsy ranges from 50% of the ovary for women at moderate risk of POI to 70%-100% of it for those at high risk. The inclusion criteria for ovarian tissue cryopreservation are women aged <35 years who cannot delay start of oncological treatments for follicle cryopreservation, with a moderate or high risk of POI and good chance of 5-year survival. Ovarian tissue cryopreservation cannot be performed if tumor treatments include uterine irradiation or for tumors at risk of ovarian metastases (as in the case of ovarian cancer, leukemia, neuroblastoma, or Burkitt lymphoma). Despite widespread adoption of vNOTES in gynecology, ovarian biopsy for cryopreservation has never been performed using this route. DESIGN: Step-by-step explanation of the procedure with descriptive text and narrated video footage. SETTING: Tertiary-level referral academic center. PATIENT(S): A 27-year-old patient recently diagnosed with low-grade follicular non-Hodgkin lymphoma was referred to our center for ovarian tissue cryopreservation before chemotherapy. The patient included in this study gave informed consent for publication of the video and posting of the video online including social media, the journal website, scientific literature websites (e.g., PubMed, ScienceDirect, and Scopus), and other applicable sites. Because of the nature of the study, institutional review board approval was not required. INTERVENTION(S): Access to the peritoneal cavity was created by a 3-cm posterior colpotomy. The peritoneum was then opened using cold scissors and temporarily fixed to the posterior vaginal wall. The GelPOINT Mini Advanced Access Platform (Applied Medical, Rancho Santa Margarita, CA), with 1 10-mm and 2 5-mm trocars, was used as the vNOTES port. The inner Alexis ring of the GelPOINT was inserted through the colpotomy into the pouch of Douglas. A hysterometer was placed into the uterine cavity to keep the uterus anteverted during the surgery. A pneumoperitoneum was created to a pressure of 8 mm Hg, and the operating table was tilted to a 20° Trendelenburg position. A 10-mm rigid 30° camera was inserted in the inferior and larger trocar, and both ovaries were visualized. Seventy percent of the left ovary was removed with cold scissors to minimize trauma on the surgical specimen. After removal of the GelPOINT cap, ovarian biopsy was immediately picked up by the biologist of our fertility center. The ovary was coagulated with a bipolar instrument. The hysterometer was then replaced by a uterine manipulator to perform tubal patency test, and blue dye passage through both salpinges was observed. Finally, the Alexis retractor and stich on the posterior peritoneum were removed, and the vagina was sutured using interrupted stiches. The total operative time was 25 minutes. MAIN OUTCOMES MEASURE(S): Ovarian tissue biopsy for cryopreservation by vNOTES. RESULT(S): No intraoperative and postoperative complications were reported, and the patient was discharged after 24 hours from surgery. CONCLUSION(S): Vaginal natural orifice transluminal endoscopic surgery may be a feasible alternative approach to laparoscopy for ovarian tissue cryopreservation: it allows an easy access to the ovaries and removal of different tissue volumes. Patients undergoing ovarian cryopreservation may benefit from the vNOTES approach because a rapid postoperative recovery is crucial to start chemotherapy in a short time. As for other vNOTES procedures, accurate selection of patients seems to be crucial for a successful ovarian tissue cryopreservation. We believe that the inclusion and exclusion criteria reported for other gynecologic procedures performed through vNOTES may also be valid for ovarian tissue cryopreservation by vNOTES. Women at high risk of pelvic adhesions (e.g., coexistent endometriosis, previous pelvic surgery, or inflammatory pelvic disease), those with an increased body mass index or enlarged uterus, and those with cervical, vaginal, or uterine cancer cannot be considered for this approach because all these factors are associated with failure of vNOTES. On the other hand, women with no history of surgery, endometriosis, and large myomas may benefit from the vNOTES approach, and these women represent most of patients who undergo ovarian tissue cryopreservation. Further and larger studies are needed to assess the efficacy and safety of this new approach.

RESUMO

STUDY OBJECTIVE: To investigate the efficacy of laparoscopic ureteroneocystostomy in patients with deep infiltrating endometriosis (DIE) with ureteral, parametrial, and bowel involvement. DESIGN: Prospective study (Canadian Task Force classification II-2). SETTING: Tertiary referral center for endometriosis care. PATIENTS: One hundred sixty patients with DIE underwent laparoscopic radical eradication and ureteroneocystostomy between January 2009 and December 2016. INTERVENTIONS: Laparoscopic nerve-sparing radical treatment with ureteroneocystostomy, parametrectomy, and, if necessary, segmental bowel resection. MEASUREMENTS AND MAIN RESULTS: Surgical eradication was radical, and ureteral endometriosis was histologically confirmed in all patients (45.6% intrinsic and 54.4% extrinsic). In 58.7% of patients ureteroneocystostomy was performed with the psoas hitch technique. Bowel resection was performed in 121 patients (75.6%), and 115 of them had a concomitant ileostomy (71.9%). Unilateral parametrectomy was performed on the left side in 61.9% of patients and on the right side in 30% of patients, respectively, whereas bilateral parametrectomy was completed in 33 patients (20.6%). Postoperative complications were infrequent: 7 patients underwent reoperation (4.4%), 8 patients experienced fever (5%), 4 patients required blood transfusion (2.5%), 3 patients had intestinal fistulas (1.9%), and 24 patients experienced impaired bladder voiding (15%) after 6 months. Mean follow-up time was 20.5 months (range, 1-60). The study reported good clinical and surgical results, with a regression of symptoms (p < .001) and recurrence of parametrial endometriosis of 1.2% that required opposite-side ureteroneocystostomy. CONCLUSION: This is the largest documented series of patients with DIE undergoing laparoscopic radical eradication and ureteroneocystostomy. The collected data show that in patients with ureteral endometriosis, this technique is feasible, effective, and safe and provides good results in terms of relapses and symptoms' control.

RESUMO

BACKGROUND AND OBJECTIVES: Symptomatic uterine adenomyosis, unresponsive to medical therapy, is a challenging condition for patients who desire to preserve their uterus. This study was an evaluation of the feasibility and efficacy of laparoscopic radiofrequency thermal ablation of symptomatic nodular uterine adenomyosis. METHODS: Fifteen women with symptomatic nodular adenomyosis, who had no plans for pregnancy but declined hysterectomy, underwent radiofrequency thermal ablation. Ultrasonography was performed at baseline and at postoperative follow-ups at 3, 6, 9, and 12 months. The impact of uterine adenomyosis-related symptoms was assessed according to the visual analog scale. RESULTS: The median number of nodular lesions treated per patient was 1 (range, 1-2). The median baseline volume of the adenomyosis area was 60 cm(3) (range, 18-128). The median reduction in volume was 32, 49.4, 59.6, and 65.4% at 3, 6, 9, and 12 months, respectively. A significant progressive improvement in the symptoms score was observed at the 4 follow-ups. CONCLUSION: In this study, laparoscopic radiofrequency thermal ablation reduced uterine adenomyosis-related symptoms and volume, with significant relief of symptoms.

RESUMO

We describe a case of giant cystic uterine adenomyoma that was diagnosed and treated by hysteroscopy. In a 27-year-old woman with menometrorrhagia, severe dysmenorrhea, and chronic pelvic pain, pelvic ultrasonography revealed an enlarged uterine cavity filled with homogeneous low echogenic fluid content. A large cornual hematometra of 8.0 cm in diameter in a bicornuate uterus was suspected, and this hypothesis was also supported by magnetic resonance imaging findings. On the contrary, hysteroscopy revealed a bilocular huge cystic lesion of the posterior uterine wall that was removed by means of monopolar loop resection. The operative finding and the histopathologic examination confirmed the diagnosis of cystic adenomyoma of the uterus. Hysteroscopy may represent a valid tool for diagnosis and minimally invasive treatment of cystic adenomyoma, including those of large volume. Its use is helpful in differential diagnosis between cystic adenomyoma and uterine malformations as a possible cause of pelvic pain.

RESUMO

UNLABELLED: Effective oncoprotein-targeted therapies have not yet been developed for ovarian cancer. To explore the role of PI3 kinase/AKT signaling in this disease, we performed a genetic and functional analysis of ovarian cancer cell lines and tumors. PI3K pathway alterations were common in both, but the spectrum of mutational changes differed. Genetic activation of the pathway was necessary, but not sufficient, to confer sensitivity to selective inhibition of AKT and cells with RAS pathway alterations or RB1 loss were resistant to AKT inhibition, whether or not they had coexistent PI3K/AKT pathway activation. Inhibition of AKT1 caused growth arrest in a subset of ovarian cell lines, but not in those with AKT3 expression, which required pan-AKT inhibition. Thus, a subset of ovarian tumors are sensitive to AKT inhibition, but the genetic heterogeneity of the disease suggests that effective treatment with AKT pathway inhibitors will require a detailed molecular analysis of each patient's tumor. SIGNIFICANCE: A subset of ovarian cancers exhibits AKT pathway activation and is sensitive to selective AKT inhibition. Ovarian tumors exhibit significant genetic heterogeneity and thus an individualized approach based on real-time, detailed genomic and proteomic characterization of individual tumors will be required for the successful application of PI3K/AKT pathway inhibitors in this disease.

RESUMO

To evaluate the accuracy of Transrectal Sonography (TRS) and a new technique, Transvaginal Sonography with Water-Contrast in the Rectum (RWC-TVS), in the diagnosis of rectosigmoid endometriosis, and the accuracy of Barium Enema (BE) and RWC-TVS in the detection of intestinal stenosis due to endometriosis. In a prospective study, we compared the findings of TRS and RWC-TVS performed before surgery with the operative and pathologic findings in 61 consecutive patients who underwent laparoscopy or laparotomy for suspected rectosigmoid endometriosis. The accuracy of BE and RWC-TVS in the detection of intestinal stenosis was evaluated comparing the radiologic and ultrasonographic results with the macroscopic findings at surgery and pathology. RWC-TVS diagnosed rectosigmoid endometriosis with the same accuracy of TRS and was equally efficient as BE in the detection of a significant intestinal lumen stenosis. For the diagnosis of rectosigmoid endometriosis the sensitivity, specificity, positive and negative predictive values of TRS and RWC-TVS were 88.2% and 96%, 80%, and 90%, 95.7%, and 98%, and 57.1% and 81.8%, respectively. For the detection of intestinal stenosis the sensitivity, specificity, positive and negative predictive values of BE and RWC-TVS were 93.7% and 87.5%, 94.2% and 91.4%, 88.2% and 82.3%, and 97% and 94.1%, respectively. RWC-TVS is a new, simple technique for a single-step and accurate preoperative assessment of rectosigmoid endometriosis.

RESUMO

OBJECTIVE: The purpose of this study was to compare the effectiveness of topically applied lidocaine-prilocaine (EMLA) cream with local anesthetic infiltration in the reduction of pain during perineal suturing after childbirth. STUDY DESIGN: Sixty-one women with either an episiotomy or a perineal laceration after vaginal delivery were assigned randomly to receive either the application of EMLA cream (n = 31) or infiltration with mepivacaine (n = 30) before perineal suturing. Primary outcome was pain during perineal repair. RESULTS: Women in the EMLA group had lower pain scores than those in the mepivacaine group (1.7 +/- 2.4 vs 3.9 +/- 2.4; P = .0002). The proportion of women who needed additional anesthesia was similar in the 2 groups (3/30 vs 5/31; P = .71). A significantly higher proportion of women expressed satisfaction with anesthesia method in the EMLA group, compared with the mepivacaine group (83.8% vs 53.3%; P = .01) CONCLUSION: EMLA cream appears to be an effective and satisfactory alternative to local anesthetic infiltration for the relief of pain during perineal repair.

RESUMO

BACKGROUND: Over the past decade an increasing demand for uterine-sparing treatment to manage symptomatic uterine myomas has become apparent in women's health care. A preliminary report showed that radiofrequency ablation (RFA) of uterine fibroids under laparoscopic guidance was a safe and effective minimally invasive approach with encouraging short-term results. The purpose of this study was to evaluate the midterm outcomes of radiofrequency ablation (RFA) of uterine myomas in terms of durability of symptom control and level of health-related quality of life. METHODS: Consecutive women with symptomatic uterine myomas, no plans for future pregnancy, and who declined hysterectomy were offered RFA ablation of uterine fibroids under laparoscopic guidance. Only 25 patients who completed at least the one-year follow-up assessment were included in the study group. Follow-up evaluations were scheduled at 1, 3, 6, 9, and 12 months and thereafter annually following the procedure. Improvement in myoma-related symptoms and impact on quality of life were assessed using a validated questionnaire (UFS-QOL). RESULTS: The median number of myomas treated per patient was 1 (range = 1-3). The median baseline volume of the dominant myoma was 76.8 cm3 (range = 14.8-332.8). No intraoperative or postoperative complications occurred. The median follow-up time was 24 months, with nine women completing three years of follow-up. The median reduction in myoma volume was 68.8% and 77.9% at six months and one year, respectively. No further change in fibroid size was observed at two years and three years. One year after the procedure, one woman (4%) underwent hysterectomy for recurrence of fibroid-related symptoms. Quality-of-life measures showed significant and durable improvement compared with baseline. CONCLUSIONS: RFA of symptomatic fibroids seems a valuable alternative to major surgery, with durable symptom relief for most patients and a low chance of recurrence at midterm.

RESUMO

OBJECTIVE: The purpose of this study was to evaluate the feasibility and efficacy of laparoscopic radiofrequency ablation of uterine fibroids. STUDY DESIGN: Eighteen women with symptomatic intramural uterine myomas underwent radiofrequency ablation under laparoscopic guidance. Postoperative sonographic evaluations of the fibroids size were scheduled at 1, 3, 6 ,9, and 12 months. The impact of myoma-related symptoms on quality of life (QOL) was assessed using a validated questionnaire. RESULTS: The median number of myomas treated per patient was 1 (1-3). The median baseline volume of the dominant myoma was 67.2 cm 3 (14.8-332.8). No intraoperative or postoperative complications occurred. The median reductions in myomas volume were 41.5%, 59%, and 77% at 1, 3, and 6-months, follow-up evaluation, respectively. No further change in fibroid size was observed at 9 months and 1 year. A significant improvement in the symptoms score and QOL score was observed at 3 and 6 months, follow-up. CONCLUSION: In this pilot study, laparoscopic radiofrequency ablation successfully reduced fibroid symptoms and fibroid volume in short-term follow-up. Additional studies are needed before its efficacy and safety can be confirmed.
