RESUMEN

INTRODUCTION: This was a single-center pilot study that sought to describe an innovative use of 4DryField® PH (premix) for preventing the recurrence of intrauterine adhesions (IUAs) after hysteroscopic adhesiolysis in patients with Asherman's syndrome (AS). MATERIAL AND METHODS: Twenty-three patients with AS were enrolled and 20 were randomized (1:1 ratio) to intrauterine application of 4DryField® PH (n = 10) or Hyalobarrier® gel (n = 10) in a single-blind manner. We evaluated IUAs (American Fertility Society [AFS] score) during initial hysteroscopy and second-look hysteroscopy one month later. Patients completed a follow-up symptoms questionnaire three and reproductive outcomes questionnaire six months later. RESULTS: The demographic and clinical characteristics, as well as severity of IUAs, were comparable in both groups. The mean initial AFS score was 9 and 8.5 in the 4DryField® PH and Hyalobarrier® gel groups, respectively (p = .476). There were no between-group differences in AFS progress (5.9 vs. 5.6, p = .675), need for secondary adhesiolysis (7 vs. 7 patients, p = 1), and the follow-up outcomes. CONCLUSION: 4DryField® PH could be a promising antiadhesive agent for preventing the recurrence of IUAs, showing similar effectiveness and safety to Hyalobarrier® gel. Our findings warrant prospective validation in a larger clinical trial. CLINICAL TRIAL REGISTRY NUMBER: ISRCTN15630617.

RESUMEN

OBJECTIVE: The aim of this study was to analyze the clinical and reproductive outcomes of patients treated with myomectomy who were histologically diagnosed with uterine smooth muscle tumor of uncertain malignant potential (STUMP). METHODS: Patients who were diagnosed with STUMP and underwent a myomectomy at our institution between October 2003 and October 2019 were identified. Variables of interest obtained from the institution's database included patient age, relevant medical history, pre-operative appearance of the tumor on ultrasound, parameters of the surgical procedure, histopathological analysis of the tumor, post-operative clinical course, and course of follow-up, including reinterventions and fertility outcomes. RESULTS: There were a total of 46 patients that fulfilled the criteria of STUMP. The median patient age was 36 years (range, 18-48 years) and the mean follow-up was 47.6 months (range, 7-149 months). Thirty-four patients underwent primary laparoscopic procedures. Power morcellation was used for specimen extraction in 19 cases (55.9% of laparoscopic procedures). Endobag retrieval was used in nine patients and six procedures were converted to an open approach due to the suspicious peri-operative appearance of the tumor. Five patients underwent elective laparotomy due to the size and/or number of tumors; three patients had vaginal myomectomy; two patients had the tumor removed during planned cesarean section; and two underwent hysteroscopic resection.There were 13 reinterventions (five myomectomies and eight hysterectomies) with benign histology in 11 cases and STUMP histology in two cases (4.3% of all patients). We did not observe any recurrence as leiomyosarcoma or other uterine malignancy. We did not observe any deaths related to the diagnosis. Twenty-two pregnancies were recorded among 17 women, which resulted in 18 uncomplicated deliveries (17 by cesarean section and one vaginal), two missed abortions, and two pregnancy terminations. CONCLUSIONS: Our study found that uterus-saving procedures and fertility-preservation strategies in women with STUMP are feasible, safe, and seem to be associated with a low risk of malignant recurrence, even while maintaining the mini-invasive laparoscopic approach.

RESUMEN

OBJECTIVE: The purpose of this study was to evaluate the appropriate surgical treatment of adenomyosis and its impact on reproductive outcomes. CONCLUSION: Patients with adenomyosis and fibroids may show a lower pregnancy rate and higher miscarriage rate than healthy individuals. However, there is no standard protocol for their optimal treatment, particularly in pregnancy-seeking or infertile women. Myomectomy is generally a commonly performed procedure that preserves fertility. On the other hand, the role of surgery in extensive uterine adenomyosis remains controversial, because adenomyosis often involves the whole uterus diffusely. It is almost impossible to remove all pathological tissue from the surrounding myometrium. Therefore, this procedure is called debulking/cytoreductive surgery. However, adenomyomectomy has also become a more common type of surgical intervention in recent years.

RESUMEN

OBJECTIVE: The aim of this study is to report a case of intramyometrial gravidity after hysteroscopic resection of retained products of conception. CASE REPORT: We report the case of a 35-year old woman who presented at 7 weeks gestation with abdominal pain in the right iliac fossa, having had caesaren section 6 months ago. She underwent hysteroscopic resection of retained products of conception 6 weeks after casesarean section. The woman was submitted to two-and three-dimensional transvaginal ultrasound. Sonography revealed intramural ectopic pregnancy. Subsequently, we decided to perform a laparoscopic artery occlusion and removal of pregnancy with adequate multiple layer closure of the myometrial defect. CONCLUSION: Conservative laparoscopic surgery can be used successfully in patients with intramyometrial pregnancy. Even though the intramural pregnancy is a very rare type of ectopic pregnancy, it should be kept in mind by gynecologists because it can become a life-threatening condition. Early dia-gnosis helps to preserve future fertility.

RESUMEN

INTRODUCTION: This study was designed to evaluate the feasibility and effectiveness of hysteroscopy in the management of symptoms related to endometrial polyps and submucous leiomyomas in women using a levonorgestrel-releasing intrauterine system (LNG-IUS). MATERIAL AND METHODS: Twenty-three LNG-IUS users presenting with endometrial polyps and/or submucous leiomyomas and irregular uterine bleeding were recruited for hysteroscopic examination and surgery. Intrauterine pathology was investigated and treated by hysteroscopic resection with the LNG-IUS in situ, and the effect of the procedure on symptoms was evaluated after three to six months. RESULTS: Intrauterine pathology was successfully resected by hysteroscopy in 23 (100.0%) out of 23 cases. Following hysteroscopy, 18 (78.3%) women reported amenorrhea, one (4.3%) regular spotting, three (13.0%) irregular spotting and one (4.3%) patient resumed normal menstrual cycle. We conclude that 19 (82.6%) patients were postoperatively asymptomatic. All procedures were uncomplicated and 4 (17.4%) were carried out without general anesthesia as office procedures. CONCLUSION: Endometrial polyps and submucous leiomyomas can develop in LNG-IUS users, and this can cause irregular uterine bleeding. Hysteroscopic resection of these pathologies is a feasible method in the clinical management of symptoms.

RESUMEN

STUDY OBJECTIVE: Women with adenomyosis may show a lower pregnancy rate and a higher miscarriage rate than healthy women. There is also a general agreement that leiomyomas, either submucosal or intramural, negatively affect fertility, when compared with women without myomas. Some of these women may benefit from adenomyomectomy, however this cytoreductive procedure is considered invasive and technically challenging especially in severe diffuse cases. The study aimed to compare the clinical and reproductive outcomes of patients who underwent adenomyomectomy with those of patients who underwent intramural myomectomy. DESIGN: A retrospective study. SETTING: Department of Obstetrics & Gynecology, Center of Gynecological Endoscopy and Minimally Invasive surgery, First Faculty of Medicine, General University Hospital in Prague. PATIENTS: A total of 55 women who underwent surgical resection of uterine adenomyosis and 55 patients who underwent myomectomy for intramural uterine myomas were included in this study. All study participants wished to retain and possibly improve their reproductive potential. INTERVENTIONS: Between 2004 and 2019, 110 women underwent laparoscopic or open uterus-sparing surgery for clinically significant uterine adenomyosis (group A) or myomas (group B), respectively. MEASUREMENTS AND MAIN RESULTS: Two groups of women who underwent different fertility-saving procedures were compared. Although all women entering the study had declared their wish to conceive, only 28 patients in group A (group A1) and 24 women in group B (group B1) finally aimed toward pregnancy. The mean age and follow-up period was 35.0 years and 76.81 months, respectively, in group A and 34.8 years and 72.5 months, respectively, in group B. The pregnancy and delivery rates were 75.0% and 46.4%, respectively, in group A1 vs 96.0% and 70.8%, respectively, in group B1, with no significant differences between the 2 groups. The open surgical approach was significantly more frequently employed in group A (47.3% vs 16.4%; p <.01). CONCLUSION: In this study, women who underwent surgery involving the uterine muscularity, including myomectomy or adenomyomectomy, had comparable reproductive outcomes, with no significant differences.

RESUMEN

OBJECTIVE: The aim of this study is to report a case of parasitic leiomyoma in a brief literature report. CASE REPORT: A 40-year-old woman was repeatedly examined for chronic abdominal pain in 2020. Lesions presented on CT images showed suspicion of carcinomatosis or endometriosis. Her past history is a laparoscopic myomectomy and hysteroscopic transcervical resection of myoma. CONCLUSION: Parasitic leiomyoma or leiomyomatosis peritonealis disseminata is an extremely rare variant of uterine leiomyoma occurring outside the uterus. According to the International Federation of Gynecology and Obstetric classification, parasitic leiomyoma has been classified as type 8. Previous laparoscopic myomectomy with intraperitoneal morcellation has been implicated in its etiology. The most common symptom - if present, is abdominal pain, pressure, bloating during eating or nausea.

RESUMEN

INTRODUCTION: The aim was to compare the surgical experience and the clinical results of laparoscopic myomectomy (LM) with or without pre-treatment with ulipristal acetate (UPA). MATERIAL AND METHODS: Fifty-four women who underwent LM for intramural myomas and were pre-treated with three months of UPA were matched with 54 patients with the same procedure but no hormonal pre-treatment. All operations were performed by one team. The technical features of the procedures were reviewed and evaluated by two other laparoscopists, unaware of the eventual use of UPA. The clinical, histological, and reproductive outcomes of each patient were assessed and the results of both groups were compared. RESULTS: The groups did not significantly differ in operation time, intra-operative blood loss, drop in hemoglobin concentration, number of complications, pregnancy rate, and delivery rate. Women pre-treated with UPA had significantly longer hospital stays, higher numbers of histologically abnormal leiomyomas, and higher rates of fibroids peri-procedurally assessed as soft and disintegrating. The other four technical parameters of LM were comparable in both groups. CONCLUSIONS: The surgeons performing LM in women pre-treated with UPA should be aware of the abnormal texture of enucleated myomas. Nevertheless, this does not negatively affect the other surgical and clinical outcomes of these patients.

RESUMEN

The levonorgestrel-releasing intrauterine system (LNG-IUS) is widely used and recommended as a reliable contraceptive. It also acts by opposing the effects of estrogen on the endometrium, thereby preventing development of endometrial hyperplasia and its possible malignant transformation. This case describes a 52-year-old multiparous amenorrhoeic patient who was seen in the gynecology outpatient department for a routine control 46 months after the insertion LNG-IUS as contraception. Hysteroscopy with a target biopsy following suspicious ultrasound scan confirmed well-differentiated endometrioid adenocarcinoma. Ultrasound scan prior to inserting LNG-IUS revealed normal 5 mm thin endometrium with the sharp edges. Uterine bleeding before the LNG-IUS insertion was regular and not excessive and the woman has remained amenorrhoeic after the LNG-IUS insertion. We present a case of the growth of a polyp-shaped endometrial carcinoma in a LNG-IUS asymptomatic user.

RESUMEN

AIM: This study was designed to evaluate feasibility and effectiveness of hysteroscopic intervention in the management of symptoms related to the displaced levonorgestrel-releasing intrauterine system (LNG-IUS). MATERIAL AND METHODS: One hundred and thirteen patients with displaced LNG-IUS presenting with irregular uterine bleeding, pelvic pain or asymptomatic displacement were recruited for hysteroscopic examination. Displaced LNG-IUS was relocated by hysteroscopic intervention and the effect on symptoms and LNG-IUS position was followed. RESULTS: The displaced LNG-IUS was successfully relocated by hysteroscope in 112 (99.1%) of 113 cases. Following LNG-IUS relocation, 71 (79.8%) patients of 89 with preoperative irregular uterine bleeding had amenorrhea or vaginal spotting, and 14 of 15 (93.3%) patients with preoperative pelvic pain became asymptomatic. LNG-IUS expulsion was recorded in two patients 7 and 21 days after hysteroscopy. CONCLUSION: Displaced LNG-IUS can cause clinical symptoms (e.g. irregular bleeding, pain). Hysteroscopic relocation of displaced LNG-IUS is a feasible method in the management of these symptoms. Risk of spontaneous expulsion associated with hysteroscopy is low.

RESUMEN

Fumarate hydratase (FH) is a key enzyme of the Krebs cycle. Germline mutations in the FH gene encoding fumarate hydratase cause autosomal dominant syndromes multiple cutaneous and uterine leiomyomata and hereditary leiomyomatosis and renal cell cancer (HLRCC). Few data have been published on the role of FH gene mutation in development of uterine fibroids outside the context of multiple cutaneous and uterine leiomyomata /HLRCC. We report two FH gene mutations, one novel and one previously described, in two young patients with sporadic uterine fibroids and decreased fumarate hydratase activity in lymphocytes. In patient 1, a novel heterozygous mutation c.892G>C was found. In patient 2 we detected heterozygous mutation c.584T>C. Both the patients had a negative family history for renal cancer and cutaneous leiomyomatosis. None of the relatives, however, underwent renal imaging at the time of writing. FH mutation carriers may be easily identified by analysis of fumarate hydratase activity in blood lymphocytes. We suggest performing fumarate hydratase activity or FH mutation screening in women with onset of uterine fibroids in their 20s and family history of uterine fibroids or other HLRCC-associated malignancies.

RESUMEN

Aim. To determine if hormonal treatment induces apoptosis in uterine fibroids. Methods. Immunohistochemical examination of fibroid tissue, using avidin-biotin complex and cleaved caspase-3 antibody for detecting apoptosis, was performed in premenopausal women who underwent 12-week treatment with oral SPRM (6 patients with 5 mg and 5 patients with 10 mg of ulipristal acetate per day) or gonadoliberin agonist (GnRHa, 17 patients) and subsequent myomectomy or hysterectomy for symptomatic uterine fibroids. Ten patients with no presurgical hormonal treatment were used as controls. Results. Apoptosis was present in a significantly higher proportion of patients treated with ulipristal acetate compared to GnRHa (P = 0.01) and to patients with no hormonal treatment (P = 0.01). In contrast to an AI of 158.9 in SPRM patients, the mean AI was 27.5 and 2.0 in GnRHa and control groups, respectively. No statistical difference in the AI was observed between the two groups of patients treated with ulipristal acetate (5 mg or 10 mg). Conclusion. Treatment with ulipristal acetate induces apoptosis in uterine fibroid cells. This effect of SPRM may contribute to their positive clinical effect on uterine fibroids.

RESUMEN

PURPOSE: To compare outcomes of two different types of occlusive therapy of uterine fibroids. METHODS: Women with fibroid(s) unsuitable for laparoscopic myomectomy (LM) were treated with uterine artery embolization (UAE) or laparoscopic uterine artery occlusion (LUAO). RESULTS: Before the procedure, patients treated with UAE (n = 100) had a dominant fibroid greater in size (68 vs. 48 mm) and a mean age lower (33.1 vs. 34.9 years) than surgically treated patients (n = 100). After 6 months, mean shrinkage of fibroid volume was 53 % after UAE and 39 % after LUAO (p = 0.063); 82 % of women after UAE, but only 23 % after LUAO, had complete myoma infarction (p = 0.001). Women treated with UAE had more complications (31 vs. 11 cases, p = 0.006) and greater incidence of hysteroscopically verified intrauterine necrosis (31 vs. 3 %, p = 0.001). Both groups were comparable in markers of ovarian functions and number of nonelective reinterventions. The groups did not differ in pregnancy (69 % after UAE vs. 67 % after LUAO), delivery (50 vs. 46 %), or abortion (34 vs. 33 %) rates. The mean birth weight of neonates was greater (3270 vs. 2768 g, p = 0.013) and the incidence of intrauterine growth restriction lower (13 vs. 38 %, p = 0.046) in post-UAE patients. CONCLUSION: Both methods are effective in the treatment of women with future reproductive plans and fibroids not suitable for LM. UAE is more effective in causing complete ischemia of fibroids, but it is associated with greater risk of intrauterine necrosis. Both methods have low rate of serious complications (except for a high abortion rate).

RESUMEN

AIM: Several atypical hysteroscopy findings have been described in association with uterine artery embolization (UAE). The purpose of this study was to evaluate the types and frequency of these findings in the largest published series of patients. MATERIAL AND METHODS: Premenopausal patients after bilateral UAE for symptomatic intramural fibroid underwent subsequent hysteroscopic examination 3-9 months following UAE. The uterine cavity was examined with focus on specific post-embolization changes. Biopsy of endometrium was obtained and evaluated together with a biopsy of abnormal foci if present. RESULTS: UAE was performed in a total of 127 women with an average size of dominant fibroid 63.1 mm in diameter and an average patient age of 35.1 years. Even though the majority of patients were asymptomatic at the time of hysteroscopy (78.0%), the post-embolization hysteroscopic examination was normal in only 51 patients (40.2%). The most frequent abnormalities included tissue necrosis (52 women, 40.9%), intracavitary myoma protrusion (45 women, 35.4%), endometrium 'spots' (22.1%), intrauterine synechiae (10.2%) and 'fistula' between the uterine cavity and intramural fibroid (6.3%). Histopathological examination showed normal, secretory or proliferative endometrium in 83.5% patients. Necrosis and/or hyalinization prevailed in the results of biopsy of abnormal loci (45 cases, 35.4%). CONCLUSION: Frequency of abnormal hysteroscopic findings several months after UAE for primary intramural myomas is high. Alarmingly high is the percentage of patients with a histopathologically verified necrosis. Performing hysteroscopy in selected patients after UAE is necessary before eventual surgical re-intervention, especially in women with reproductive plans.

RESUMEN

Myomectomy is associated with a high risk of de-novo adhesion formation that may decrease fertility. The purpose of this study was to compare the reproductive outcome of patients after laparoscopic or open myomectomy who underwent second-look (SL) hysteroscopy and laparoscopy including adhesiolysis with patients with no SL intervention. A total of 170 patients underwent open or laparoscopic myomectomy at one centre. All patients were recommended SL. Reproductive results were analyzed in 12 and 24 months intervals following myomectomy. Out of 170 post-myomectomy patients 96 signed informed consent with SL (group A) and 74 withheld (group B). The cumulative pregnancy rate in the 24-months follow-up was: 61.4% and 66.7% (p = 0.535) in group A and group B respectively. Adhesions of adnexa were observed and lysed in the overall of 34.0% of patients at the time of SL. Intrauterine synechiae were present in 1.56% of patients at the SL hysteroscopy. No case of uterine rupture during pregnancy or delivery was recorded. Our results show that the pregnancy rate of patients after myomectomy who underwent SL hysteroscopy and laparoscopy is similar to that of patients with no SL procedure. Adhesiolysis performed during SL does not seem to improve the reproductive outcome of post-myomectomy patients.

RESUMEN

We investigated the frequency of pathology, especially intrauterine adhesions, after instrumental evacuation within 24 h of delivery in a prospective observational intervention study on 100 women where a 'see and treat' hysteroscopy was performed after three to four months. There were two possible etiology groups: intrauterine adhesions [classified according by European Society for Gynaecological Endoscopy (ESGE) grades I-IV] and residual tissue (classified as minimal and considerable). Adhesions were found in 18% of patients, as follows: ESGE I-II in 13% and ESGE III-IV in 5%. Residual tissue was present in 33%, as follows: minimal in 23% and considerable in 10%. There were 6% who had both mild adhesions and minimal residual tissue, while 43% of the women had normal intrauterine findings. Of the women, 32% were symptomatic (spotting, bleeding). Only residual tissue correlated with symptoms (r=0.376; p<0.001). There is a high prevalence of acquired intrauterine pathology (57%) in women who require early instrumental evacuation.

RESUMEN

Hysteroscopic examination of the uterine cavity revealed that patients previously treated for intramural myoma(s) by uterine artery embolization had a significantly higher incidence of abnormal findings compared with patients treated by laparoscopic occlusion of uterine arteries (59.5% vs. 2.7%). In particular, there was a higher incidence of necrosis in the uterine cavity of patients subjected to uterine artery embolization (43.2%) compared with patients after surgical uterine artery occlusion (2.7%).

RESUMEN

A prospective study was conducted on the incidence of intrauterine pathology after missed abortion diagnosed and treated by hysteroscopy. A hysteroscopy was performed in 100 women four to 12 weeks after a dilatation and curettage for missed abortions. Uterine malformations were found in 12 patients, intrauterine adhesions in seven and submucous myoma in two cases. As a side finding four cases of asymptomatic retained products of conception were found. Most cases of the intrauterine pathology were treated instantly by hysteroscopy, "see and treat" regimen was preferred. Post-missed abortion-hysteroscopy is a simple and useful method for early diagnosis and treatment of congenital and acquired intrauterine pathology.

RESUMEN

BACKGROUND: Paraaortic lymph nodes represent the second level in the lymphatic spread of cervical cancer. Recent studies have confirmed the association of HPV DNA in pelvic lymph nodes in early-stage disease with metastatic involvement and a less favourable prognosis. OBJECTIVE: The aim of our study was to detect 13 high-risk genotypes of HPV in paraaortic nodes harvested from patients with FIGO IB2-IIIB tumours and correlate findings with histopathology. STUDY DESIGN: The study involved patients with advanced cervical cancer who had undergone low paraaortic lymphadenectomy. The cytobrush technique was used for perioperative sample collection from the tumour and fresh lymphatic tissue. Patients with non-HPV related cancers were used as a control group. RESULTS: The study involved 24 cervical cancer patients. High-risk HPV DNA was found in the primary tumour of all cases and in PALN in 16 (67%) cases. The most frequent genotype was HPV 16, both in the tumour and in the paraaortic lymph nodes (83% and 54%, respectively). Metastatic involvement of paraaortic lymph nodes was identified in 8 cases (33%), which all were also HPV DNA positive. No HPV DNA was detected in PALN in any of 22 control group cases. CONCLUSIONS: Using the cytobrush technique, the presence of at least one HR HPV genotype in the primary tumour was identified in all the patients. The metastatically involved paraaortic lymph nodes always contained the DNA of at least one HPV genotype present in the primary tumour. Determination of clinical significance of HR HPV DNA presence in histologically negative lymph nodes requires further follow-up of the cohort.
