A rare variant of mullerian agenesis: a case report and review of the literature.

INTRODUCTION: Menstruation is a developmental milestone and usually marks healthy and normal pubertal changes in females. Menarche refers to the onset of first menstruation in a female. The causes of primary amenorrhea include outflow tract abnormalities, resistant endometrium, primary ovarian insufficiency, and disorders of the hypothalamus, pituitary, or other endocrine glands. A rare variant of mullerian agenesis, which warrants an individualized approach to management, is presented here. CASE REPORT: We present here the case of a 25-year-old Indian female with pain in the lower abdomen and primary amenorrhea. After a thorough history, clinical examination, imaging, and diagnostic laparoscopy, two small uteri, a blind upper half vagina, bilateral polycystic ovaries, and a blind transverse connection between the two uteri-a horseshoe band cervix-were detected, which confirmed the diagnosis of mullerian agenesis. There was evidence of adenomyosis in the mullerian duct element. This is a rare form of Müllerian abnormality with an unusual presentation. CONCLUSION: Mullerian agenesis is the most common cause of primary amenorrhea with well-developed secondary sexual characteristics. There are various forms of mullerian agenesis. Most of the cases are managed by a multidisciplinary team. Rare variants warrant an individualized approach to management.

Laparoscopic Surgery: A Systematic Review of Loop and Knot Security, Varying with the Suture and Sequences, Throws, Rotation and Destabilization of Half-Knots or Half-Hitches.

Surgical knots are sequences of half-knots (H) or half-hitches (S), defined by their number of throws, by an opposite or similar rotation compared with the previous one, and for half-hitches whether they are sliding (s) or blocking (b). Opposite rotation results in (more secure) symmetric (s) knots, similar rotation in asymmetric (a) knots, and changing the active and passive ends has the same effect as changing the rotation. Loop security is the force to keep tissue together after a first half-knot or sliding half-hitches. With polyfilament sutures, H2, H3, SSs, and SSsSsSs have a loop security of 10, 18, 28, and 48 Newton (N), respectively. With monofilament sutures, they are only 7, 16, 18, and 25 N. Since many knots can reorganize, the definition of knot security as the force at which the knot opens or the suture breaks should be replaced by the clinically more relevant percentage of clinically dangerous and insecure knots. Secure knots with polyfilament sutures require a minimum of four or five throws, but the risk of destabilization is high. With monofilament sutures, only two symmetric+4 asymmetric blocking half-hitches are secure. In conclusion, in gynecology and in open and laparoscopic surgery, half-hitch sequences are recommended because they are mandatory for monofilament sutures, adding flexibility for loop security with less risk of destabilization.

Effect of Diameter and Type of Suture on Knot and Loop Security.

The loop and knot securities of two polyfilament and two monofilament sutures of four diameters (3.0, 2.0, 0, 1) were evaluated with a tensiometer for four four-throw knots, known to be secure with a 2.0 polyfilament suture. Loop security of Monocryl 1 is low, being 14.7 ± 3.0 Newton (N) for a three-throw half-knot (H3) and 15.4 ± 2.4 N and 28.3 ± 10 N for two (SSs) and four (SSsSsSs) symmetrical sliding half-hitches. This is lower than 18, 24, and 46 N for similar knots with Vicryl. Polyfilament sutures have excellent knot security for all four diameters. Occasionally, some slide open with slightly lower knot security, especially for larger diameters, although this is not clinically problematic. Knot security of monofilament sutures was unpredictable for all four knots, especially for larger diameters, resulting in many clinically insecure knots. A secure monofilament knot requires a six-throw knot with two symmetrical sliding half-hitches or two symmetrical half-knots secured with four asymmetric blocking half-hitches. In conclusion, with polyfilament sutures, four- or five-throw half-knot or half-hitch sequences result in secure knots. For monofilament sutures, loop and knot security is much less, half-knot combinations should be avoided, and secure knots require six-throw knots with four asymmetric blocking half-hitches.

The 10 "Cardinal Sins" in the Clinical Diagnosis and Treatment of Endometriosis: A Bayesian Approach.

Evidence-based data for endometriosis management are limited. Experiments are excluded without adequate animal models. Data are limited to symptomatic women and occasional observations. Hormonal medical therapy cannot be blinded if recognised by the patient. Randomised controlled trials are not realistic for surgery, since endometriosis is a variable disease with low numbers. Each diagnosis and treatment is an experiment with an outcome, and experience is the means by which Bayesian updating, according to the past, takes place. If the experiences of many are similar, this holds more value than an opinion. The combined experience of a group of endometriosis surgeons was used to discuss problems in managing endometriosis. Considering endometriosis as several genetically/epigenetically different diseases is important for medical therapy. Imaging cannot exclude endometriosis, and diagnostic accuracy is limited for superficial lesions, deep lesions, and cystic corpora lutea. Surgery should not be avoided for emotional reasons. Shifting infertility treatment to IVF without considering fertility surgery is questionable. The concept of complete excision should be reconsidered. Surgeons should introduce quality control, and teaching should move to explain why this occurs. The perception of information has a personal bias. These are the major problems involved in managing endometriosis, as identified by the combined experience of the authors, who are endometriosis surgeons.

Predictive Value of Ultrasound Imaging for Diagnosis and Surgery of Deep Endometriosis: A Systematic Review.

OBJECTIVE: To calculate the predictive value and thus the clinical usefulness of transvaginal ultrasound (US) imaging for the management of deep endometriosis, knowing that the positive predictive value (PPV) varies with the prevalence and probably with the volume and location of the disease. DATA SOURCES: After registration on PROSPERO (CRD42022366323), PubMed was searched for all reports describing the diagnostic accuracy of US imaging for deep endometriosis published between January 1, 2000, and October 20, 2022. METHODS OF STUDY SELECTION: The 536 articles on "endometriosis AND US And diagnosis" were hand searched, and 30 reports describing sensitivity and specificity of deep endometriosis were found. Besides sensitivity and specificity, the prevalence, localization, and size of deep endometriosis lesions were collected. TABULATION, INTEGRATION, AND RESULTS: Prevalences of deep endometriosis were reported only twice as 12% and 32% by ultrasonographers. In women undergoing surgery, prevalences vary between 40% and 100% because of the variable inclusion criteria. Specificity is higher than sensitivity for all locations: rectovaginal (97% [86-100] vs 74% [31-95], p = .0002), rectosigmoid (97% [63-100] vs 88% [37-97], p = .0082), vesicouterine (100% [97-100] vs 63% [22-100], p = .0021), and uterosacrals (91% [77-99] vs 68% [18-83], p = .0005). Notwithstanding improved equipment, accuracy did not vary over the last 20 years. Sensitivities or specificities have not been stratified by the size of the lesion, and thus, the lower detection limits are not known. In the absence of blinding, the usefulness for surgery could not be established. CONCLUSION: The reported sensitivities and specificities of transvaginal US are not only those of imaging but include symptoms and clinical examinations. In referral centers, the reported PPVs are high (94%-100%) given that prevalences are >10% and specificities are >95%. However, the extrapolation of the clinical use before surgical interventions should be considered with care, given that PPVs for smaller lesions and the lower detection limit are unknown and surgeons were not blinded to US results.

Ovarian Pregnancy: 2 Case Reports and a Systematic Review.

Ovarian pregnancy is a rare but well-known pathology. However, pathophysiology, diagnosis and treatment are not established. Therefore, all case reports on ovarian pregnancy published in PubMed from November 2011 till November 2022 were reviewed and two case reports were added. In these 84 case reports, 8% of ovarian pregnancies occurred in women without or with blocked oviducts and 23% were localised on the other side than the corpus luteum. Since symptoms are not specific, ovarian pregnancy has to be suspected in all women with abdominal bleeding. Surgical excision is the preferred treatment. However, since an associated intra-uterine pregnancy cannot be excluded, care should be taken not to interrupt this intra-uterine pregnancy with the uterine cannula or by damaging the corpus luteum. In conclusion, in women with abdominal bleeding, an ovarian pregnancy cannot be excluded, even in women with a negative pregnancy test or an empty uterus on transvaginal ultrasonography. Therefore, a laparoscopy is indicated but the surgeon should realise that an associated intra-uterine pregnancy also cannot be excluded and that therefore care should be taken not to interrupt this intra-uterine pregnancy by the uterine cannula or by damaging the corpus luteum.

New Understanding of Diagnosis, Treatment and Prevention of Endometriosis.

For 100 years, pelvic endometriosis has been considered to originate from the implantation of endometrial cells following retrograde menstruation or metaplasia. Since some observations, such as the clonal aspect, the biochemical variability of lesions and endometriosis in women without endometrium, the genetic-epigenetic (G-E) theory describes that endometriosis only begins after a series of cumulative G-E cellular changes. This explains that the endometriotic may originate from any pluripotent cell apart from the endometrium, that 'endometrium-like cells' can harbour important G-E differences, and that the risk is higher in predisposed women with more inherited incidents. A consequence is a high risk after puberty which decreases progressively thereafter. Considering a 10-year delay between initiation and performing a laparoscopy, this was observed in the United Arab Emirates, Belgium, France and USA. The subsequent growth varies with the G-E changes and the environment but is self-limiting probably because of the immunologic reaction and fibrosis. That each lesion has a different set of G-E incidents explains the variability of pain and the response to hormonal treatment. New lesions may develop, but recurrences after surgical excision are rare. The fibrosis around endometriosis belongs to the body and does not need to be removed. This suggests conservative excision or minimal bowel without safety margins and superficial treatment of ovarian endometriosis. This G-E concept also suggests prevention by decreasing oxidative stress from retrograde menstruation or the peritoneal microbiome. This suggests the prevention of vaginal infections and changes in the gastrointestinal microbiota through food intake and exercise. In conclusion, a higher risk of initiating endometriosis during adolescence was observed in UAE, France, Belgium and USA. This new understanding and the limited growth opens perspectives for earlier diagnosis and better treatment.

Impact of surgery for colorectal endometriosis on postoperative fertility and pregnancy outcomes.

INTRODUCTION: Deep infiltrative endometriosis can lead to infertility with a spontaneous pregnancy rate between 8.7 and 13%. Surgical treatment of bowel endometriosis may improve spontaneous and ART fertility. The aim of this study was to evaluate post-operative fertility according to the surgical technic used (shaving vs. bowel resection). MATERIAL AND METHOD: A retrospective, monocentric study was carried-out in the University Hospital of Strasbourg, France, from September 2009 to October 2016. All patients with a desire to become pregnant and treated for colorectal deep infiltrating endometriosis were included. Two groups were analyzed and compared: shaving treatment vs. digestive resection (discoid or segmental). The primary outcome was pregnancy rate after surgery. Secondary outcomes were: mode of pregnancy occurrence (spontaneous versus ART), time of onset, term at birth, occurrence of complications during pregnancy. RESULTS: 94 patients were included (39 had a bowel resection and 55 a shaving). Both groups had similar pre-operative characteristics. The pregnancy rate was 52,1% for the total population with no significant differences between the two groups (p = 0.68). However, we found a significantly higher spontaneous pregnancies rate among the resection group with 73.7% (p = 0,0086). Pregnancy complications occurred in 50% of pregnancies, regardless of the surgical technic used. CONCLUSION: This study suggests that, for patients with colorectal DIE, surgical treatment improves overall fertility. Furthermore, resection surgery seems to significantly improve the occurrence of spontaneous pregnancies. However, this surgery is not without risks and multidisciplinary discussions and thorough information to the patient are a prerequisite.

Pathogenesis Based Diagnosis and Treatment of Endometriosis.

Understanding the pathophysiology of endometriosis is changing our diagnosis and treatment. Endometriosis lesions are clones of specific cells, with variable characteristics as aromatase activity and progesterone resistance. Therefore the GE theory postulates GE incidents to start endometriosis, which thus is different from implanted endometrium. The subsequent growth in the specific environment of the peritoneal cavity is associated with angiogenesis, inflammation, immunologic changes and bleeding in the lesions causing fibrosis. Fibrosis will stop the growth and lesions look burnt out. The pain caused by endometriosis lesions is variable: some lesions are not painful while other lesions cause neuroinflammation at distance up to 28 mm. Diagnosis of endometriosis is made by laparoscopy, following an experience guided clinical decision, based on history, symptoms, clinical exam and imaging. Biochemical markers are not useful. For deep endometriosis, imaging is important before surgery, notwithstanding rather poor predictive values when confidence limits, the prevalence of the disease and the absence of stratification of lesions by size, localization and depth of infiltration, are considered. Surgery of endometriosis is based on recognition and excision. Since the surrounding fibrosis belongs to the body with limited infiltration by endometriosis, a rim of fibrosis can be left without safety margins. For deep endometriosis, this results in a conservative excision eventually with discoid excision or short bowel resections. For cystic ovarian endometriosis superficial destruction, if complete, should be sufficient. Understanding pathophysiology is important for the discussion of early intervention during adolescence. Considering neuroinflammation at distance, the indication to explore large somatic nerves should be reconsidered. Also, medical therapy of endometriosis has to be reconsidered since the variability of lesions results in a variable response, some lesions not requiring estrogens for growth and some being progesterone resistant. If the onset of endometriosis is driven by oxidative stress from retrograde menstruation and the peritoneal microbiome, medical therapy could prevent new lesions and becomes indicated after surgery.

Laparoscopic management of advanced epithelial ovarian cancer after neoadjuvant chemotherapy: a phase II prospective multicenter non-randomized trial (the CILOVE study).

OBJECTIVE: The aim of this study was to explore the feasibility and safety of the laparoscopic approach after neoadjuvant chemotherapy among selected chemosensitive patients with advanced ovarian cancer. METHODS: The CILOVE study was a phase II prospective non-randomized multicenter study. It aimed to enroll 47 women with unresectable disease at the time of initial diagnosis (International Federation of Gynecology and Obstetrics (FIGO) stage IV and/or diffuse extensive carcinomatosis for advanced FIGO stage IIIC or patients unfit to withstand radical primary surgery), in response to chemotherapy and fit to undergo laparoscopy. RESULTS: Among the 48 patients enrolled in the trial, 44 (92%) patients underwent exploratory staging laparoscopy and, as a result, 41 patients were eligible for cytoreductive surgery. Among them, 32 were intended to be managed by laparoscopy and nine patients were managed by laparotomy. The conversion rate to laparotomy was 9.4% (3/32) and the reasons were multiple surgical adhesions (n=1), miliary carcinomatosis and adhesion to the intraperitoneal mesh (n=1), and poor laparoscopic evaluation of transverse colon involvement (n=1). All except one patient had optimal cytoreduction (97% complete cytoreduction, 3% incomplete cytoreduction (residual tumor <2.5 mm)). The median operative time was 267 min (range 146-415) and the median estimated blood loss was 150 mL (range 0-500). Two patients had intra-operative complications: one diaphragm rupture that was repaired during laparoscopy and one bradycardia. Six patients experienced early post-operative complications (<1 month), but there were no grade 3 and 4 complications (3 infections, 1 lymphoedema, 2 hemorrhage). After cytoreductive laparoscopy, the percentage of patients without progression at 12 months was 87.5%. CONCLUSIONS: Interval ovarian cytoreduction by a laparoscopic approach is safe and feasible for patients with a favorable response to chemotherapy. With the widespread use of neoadjuvant chemotherapy in the management of advanced ovarian cancer, a minimally invasive approach may be a potential option.

Surgical management of endometriosis-associated pain.

Endometriosis and pelvic pain are associated. However, only half of the subtle and typical, and not all cystic and deep lesions are painful. The mechanism of the pain is explained by cyclical trauma and repair, an inflammatory reaction, activation of nociceptors up to 2.7 cm distance, painful adhesions and neural infiltration. The relationship between the severity of lesions and pain is variable. Diagnosis of the many causes requires laparoscopy and expertise. Imaging cannot exclude endometriosis. Surgical removal is the treatment of choice. Medical therapy without a diagnosis risks missing pathology and chronification of pain if not 100% effective. Indications and techniques of surgery are described as expert opinion since randomised controlled trials were not performed for ethical reasons, since not suited for multimorbidity while a control group is poorly accepted. Subtle endometriosis needs destruction since some cause pain or progress to more severe disease. Typical lesions need excision or vaporisation since depth can be misjudged by inspection. Painful cystic ovarian endometriosis needs adhesiolysis and either destruction of the lining or excision of the cyst wall, taking care to avoid ovarian damage. Cysts larger than 6 cm need a two-step technique or an ovariectomy. Excision of deep endometriosis is difficult and complication prone surgery involving bladder, ureter, and bowel surgery varying from excision and suturing, disc excision with a circular stapler and resection anastomosis. Completeness of excision, prevention of postoperative adhesions and recurrences of endometriosis, and the indication to explore large somatic nerves will be discussed.

Prevalence of Endometriosis and Peritoneal Pockets in Women with Infertility and/or Pelvic Pain.

OBJECTIVE: To evaluate the prevalence of endometriosis and peritoneal pockets and to analyze whether these pockets are associated with pain. METHODS: Analysis of prospectively registered data of all women undergoing laparoscopy for infertility or pelvic pain between 1988 and 2011 at KU Leuven University Hospital. RESULTS: Of 4497 women, 191 had 238 pockets, with a prevalence of 4.7% in women with infertility only, 4.9% in women with infertility and pelvic pain, and 3.5% in women with pelvic pain only (P = 0.045 for all infertility vs. pelvic pain only). Prevalence did not vary by age. Pockets were associated with endometriosis (P < 0.0001), which was found in 77% of women with pockets. Among women with infertility only, the prevalence of endometriosis was higher in women with pockets (P = 0.0001) than in women without. The prevalence of endometriosis was similar in women with infertility and pelvic pain or pelvic pain only. Pelvic pain as an indication for surgery was associated simultaneously (through logistic regression) with endometriosis (P < 0.0001) and pockets (P = 0.040). Pelvic pain severity was associated simultaneously with pockets (P = 0.0026) and the severity of subtle (P = 0.001), typical (P = 0.030), cystic ovarian (P = 0.051), and deep endometriosis (P < 0.0001). Pelvic pain severity was not associated with endometriosis in the pockets or the diameter or location of pockets. CONCLUSIONS: The prevalence of pockets was low, at between 3.5% and 5%. Women with infertility only and pockets had more endometriosis than women without. Severe pelvic pain and pelvic pain as an indication for surgery were associated with the presence of pockets as well as the presence and severity of endometriosis.

Stepwise Laparoscopic Myomectomy and the Baseball Closure.

STUDY OBJECTIVE: To demonstrate the importance of planning all the steps of laparoscopic myomectomy, including incision, techniques to reduce blood loss, and suturing. DESIGN: Step-by-step video demonstration of the technique, with narration in the background. The video was approved by the local institutional review board. SETTING: Live surgery at Hospital PIO XII, Institute for Research into Cancer of the Digestive System and American Institute of Telesurgery, Barretos. INTERVENTIONS: We describe a case of a 33-year-old woman with no pregnancy and diagnosed with endometriosis and chronic pelvic pain associated with a 5-cm posterior transmural myoma. We performed a laparoscopic myomectomy, with temporary clipping of the uterine arteries associated with the treatment of endometriosis lesions. Specimen extraction was performed inside a bag [1]. The patient was discharged the next day with no complications. Ten months after the procedure, the patient reported that there was no pain, and that her menses were normal. CONCLUSION: The laparoscopic approach remains the gold standard for myomectomy [2]. Planning the steps before execution is fundamentally important to ensure the security of the procedure. A seromuscularis baseball suture associated with figure-of-8 knotting with an H3H2 sequence at the internal layers seems to be an adequate technique for myometrium closure [3]. Choosing the correct angle for the incision, clipping the uterine artery, and developing the suture in 2 layers results in less bleeding, reduced operating time, decrease in hospital length of stay, and fewer complications.

The epidemiology of endometriosis is poorly known as the pathophysiology and diagnosis are unclear.

As the diagnosis requires a laparoscopy, we only have data in women with pain and/or infertility. Endometriosis has been considered to be a single disease defined as 'endometrium like glands and stroma outside the uterus'. However, subtle, typical, cystic ovarian and deep endometriosis lesions should be considered to be different pathologies which occur in all combinations and with different severities. All large datasets, especially those based on hospital discharge records, consider endometriosis to be a single disease without taking into account severity. In particular, the variable prevalence and recognition of subtle lesions is problematic. Reliable surgical data are small series not permitting multivariate analysis. Endometriosis is a hereditary disease. The oxidative stress of heavy menstrual bleeding with retrograde menstruation and an altered pelvic microbiome are probably associated with increasingly severe endometriosis. Whether the prevalence is increasing, or whether endometriosis is associated with fat intake or an increased risk of cardiovascular disease is unclear.

Which Knots Are Recommended in Laparoscopic Surgery and How to Avoid Insecure Knots.

STUDY OBJECTIVE: To investigate why security of identical knot sequences is variable and how to avoid occasionally insecure knots. DESIGN: A factorial design was used to assess factors affecting the security of half knot (H) and half-hitch (S) knot combinations. The effect of tying forces and the risk factors to transform H knots into S knots were investigated. The risk factors evaluated were as follows: starting with an H1 or H2 instead of an H3 knot, inexperience, short sutures, and monomanual knot tying. Security of transformed knots, S2S1 and S2S2 knots, and their recuperation with 2 additional half hitches, SSb or SbSb, were evaluated. SETTING: Training center for laparoscopic suturing. PATIENTS: Not applicable. INTERVENTIONS: Security of knots was evaluated in vitro. MEASUREMENTS AND MAIN RESULTS: The forces that caused knot combinations to open before breaking of the suture were used to calculate the risk of opening with low forces. Tying more strongly increased the security of half knots (H2H1sH1s) (p <.02) and half hitches (p <.001). The forces needed to transform an H3 into an S3 are higher than those for an H2 (p <.001), and the risk increases when the surgeon is inexperienced (p <.001), when sutures are short (p <.001), and when monomanual knot tying (p <.001) is used. Inadvertently made S2S1 and S2S2 knots are dangerous, with the exception of the symmetric S2S2, which is stable. Unstable knots such as S2S1a and S2S2a knot combinations improve with 2 additional blocking half hitches (SbSb), but S2S2aSbSb remains occasionally insecure. CONCLUSION: To reduce the risk of accidentally transforming a first H into an S knot, it is recommended to start with an H3, tie with force, avoid short sutures, and use bimanual suturing. This permits the recommendation to use preferentially H3H2 knots or 5 half hitches (SSSbSbSb). When in doubt, half knot combinations should be secured with at least 2 blocking half hitches.

Application of Indocyanine Green in Gynecology: Review of the Literature.

The present review aims to analyze the current data available on the different applications of indocyanine green (ICG) in gynecology. A semantic review of English-language publications was performed by searching for MeSH terms and keywords in the PubMed and Google Scholar databases. The studies were finally selected by one author according to the aim of this review. ICG is a highly water-soluble tricarbocyanine dye that fluoresces in the NIR spectrum. Approved by the FDA in 1959, it can be administered either IV (usual dose of 5 mg) or locally/submucosally (usual dose of 5-6.25 mg) according to the pathology or indication. It is used most often in the setting of oncology, endometriosis and other gynecological conditions. In oncological applications, ICG is used to identify sentinel lymph nodes (SLN) using near-infrared light in endometrial, cervical and vulvar cancers. The main advantages that it offers include a reduction of surgical time, improved SLN detection rates, and the ability to avoid radioactivity. In cases of endometrial (submucosal or hysteroscopic applications) or cervical (intracervical administration) cancer, ICG can detect SLN at an accuracy of 95% to 98%. For vulvar cancer, the SLN detection rate can reach 100%. In endometriosis, the lack of good evidence hinders the final evaluation of this method in both diagnostic and therapeutic scenarios. An analytical, well-designed, prospective study is currently underway.

Total Laparoscopic Hysterectomy for Endometriosis and an Arteriovenous Malformation.

STUDY OBJECTIVE: To show laparoscopic management of an arteriovenous malformation in a patient with deep pelvic endometriosis DESIGN: A step-by-step explanation of the surgery using an instructive video. SETTING: Hautepierre University Hospital, Strasbourg, France. INTERVENTIONS: We describe the case of a 37-year-old patient presenting with deep pelvic endometriosis and a uterine arteriovenous malformation. Deep pelvic endometriosis was diagnosed during a tubal ligation in 2015. Laparoscopy also showed some pelvic varicosities. Hysteroscopy was performed to increase the diagnostic precision. Huge blood vessels with an arterial pulse on the anterior wall of the uterus were found. The endometriosis of the patient was very symptomatic; she suffered from dysmenorrhea, menorrhagia, intense dyspareunia, and dyschezia. Magnetic resonance imaging indicated a large arteriovenous shunt in the anterior part of the uterus and bladder endometriosis. After a pluridisciplinary medical staff meeting, we decided to begin treatment with luteinizing hormone-releasing hormone analogs. Then, she underwent embolization of the arteriovenous malformation, which produced regression of the lesions as indicated by reevaluation with magnetic resonance imaging. We decided to perform laparoscopic hysterectomy. Evaluation of the abdominal cavity showed diaphragm endometriosis, deep pelvic endometriosis, and the arteriovenous malformation. We started with left ureterolysis and opening of the rectovaginal septum. After that, we radically dissected the left side of the uterus with a left oophorectomy and then the right side, conserving the ovary. Then, we shaved the bladder for endometriosis removal. To finish, we performed a right salpingectomy with a right ovariopexy, vaginal closure, and coagulation of the diaphragm's nodules. The patient agreed to record and publish the surgery, and the local institutional review board gave its approval. CONCLUSION: To conclude, preoperative embolization of the arteriovenous shunt improves surgery, avoiding excessive bleeding and permitting easier radical hysterectomy for deep pelvic endometriosis. Similar cases have been published [1], but to our knowledge, our video is the first regarding this subject. It appears that embolization can fail, but hysterectomy remains the gold standard treatment [2].
