Percutaneous cryoablation of symptomatic uterine adenomyomas: Initial experience.

OBJECTIVE: To assess the efficacy and safety of percutaneous image-guided cryoablation of adenomyomas MATERIAL AND METHODS: Five symptomatic women who wanted to preserve their uterus and fertility underwent a single session of percutaneous image-guided cryoablation of adenomyoma. Three to six 17-gauge cryoprobes were introduced percutaneously into the adenomyoma under ultrasound and laparoscopy guidance. Clinical efficacy was defined as the diminution of the Visual Analogue Scale of pain (VAS), the decrease in uterine bleeding and the improvement of quality of life assessed by the endometriosis health profile 5 (EHP-5) 12 months after treatment. Technical efficacy was defined by the reduction in volume of each treated adenomyoma on MRI. Complications were classified using the Clavien-Dindo classification system. Hysterosonography was performed at least 3 months after the procedure. RESULTS: Compared to the baseline, all symptom scores had decreased after 12 months: median VAS 8/10 (range, 5-10) to 4/10 (range, 0-7); median dyspareunia score 7/10 (range, 0-10) to 2/10 (range, 0-8); median bleeding score 335 (range, 102-920) to 76 (range, 0-88); median EHP-5 score 60/100 (range, 50-75) to 50/100 (range, 32-55). The median volume of adenomyosis decreased from 57 cm3 (range, 8-87) to 9 cm3 (range, 2-45) at 12 months. No postoperative complications occurred. Two patients had incomplete intrauterine adhesions that were easily removed hysteroscopically. CONCLUSION: Cryoablation may be a promising alternative treatment for symptomatic adenomyoma in women who want to preserve their uterus.

Adenomyomas of the Gallbladder: An Analysis of Frequency, Clinicopathologic Associations, and Relationship to Carcinoma of a Malformative Lesion.

CONTEXT.­: The nature and associations of gallbladder (GB) "adenomyoma" (AM) remain controversial. Some studies have attributed up to 26% of GB carcinoma to AMs. OBJECTIVE.­: To examine the true frequency, clinicopathologic characteristics, and neoplastic changes in GB AM. DESIGN.­: Cholecystectomy cohorts analyzed were 1953 consecutive cases, prospectively with specific attention to AM; 2347 consecutive archival cases; 203 totally embedded GBs; 207 GBs with carcinoma; and archival search of institutions for all cases diagnosed as AM. RESULTS.­: Frequency of AM was 9.3% (19 of 203) in totally submitted cases but 3.3% (77 of 2347) in routinely sampled archival tissue. A total of 283 AMs were identified, with a female to male ratio = 1.9 (177:94) and mean size = 1.3 cm (range, 0.3-5.9). Most (96%, 203 of 210) were fundic, with formed nodular trabeculated submucosal thickening, and were difficult to appreciate from the mucosal surface. Four of 257 were multifocal (1.6%), and 3 of 257 (1.2%) were extensive ("adenomyomatosis"). Dilated glands (up to 14 mm), often radially converging to a point in the mucosa, were typical. Muscle was often minimal, confined to the upper segment. Nine of 225 (4%) revealed features of a duplication. No specific associations with inflammation, cholesterolosis, intestinal metaplasia, or thickening of the uninvolved GB wall were identified. Neoplastic change arising in AM was seen in 9.9% (28 of 283). Sixteen of 283 (5.6%) had mural intracholecystic neoplasm; 7 of 283 (2.5%) had flat-type high-grade dysplasia/carcinoma in situ. Thirteen of 283 cases had both AM and invasive carcinoma (4.6%), but in only 5 of 283 (1.8%), carcinoma arose from AM (invasion was confined to AM, and dysplasia was predominantly in AM). CONCLUSIONS.­: AMs have all the features of a malformative developmental lesion, and may not show a significant muscle component (ie, the name "adeno-myoma" is partly a misnomer). While most are innocuous, some pathologies may arise in AMs, including intracholecystic neoplasms, flat-type high-grade dysplasia or carcinoma in situ, and invasive carcinoma (1.8%, 5 of 283). It is recommended that gross examination of GBs include serial slicing of the fundus for AM detection and total submission if one is found.

Gastric type III heterotopic pancreas presenting as adenomyoma in the antrum of the stomach: a case report.

Although heterotopic pancreas usually occurs in the stomach and rarely presents as a submucosal tumor, an accurate preoperative diagnosis is often difficult because of the variety of clinical symptoms and findings depending on the size and location of the lesion. We experienced a case of gastric type III heterotopic pancreas presenting as a gastric adenomyoma in the antrum of the stomach. A 62-year-old woman visited a local hospital for epigastric discomfort. An esophagogastroduodenoscopy study indicated a submucosal tumor in the greater curvature of the gastric antrum. The patient underwent surgical resection of the tumor because it was enlarged. The histological sections of the resected specimen showed that the tumor was composed of ductular structures lined by tall columnar epithelia and a prominent smooth muscle stroma with no atypical cells. The tumor was compatible with Heinrich's type III heterotopic pancreas, which presented as an adenomyoma of the stomach. These findings provide useful histological features and some insight into a better understanding of the embryonic origin and development of adenomyoma and heterotopic pancreas in the antrum of the stomach.

Extrauterine adenomyoma: A case report and systematic review of the literature.

OBJECTIVE: To describe a case of extrauterine adenomyoma (EA) and review all the cases of EA in the literature. METHODS: Pubmed/MEDLINE, Embase, and Google Scholar from 1807 to December 2022. All studies reporting the histologic diagnosis of an EA. We collected the following data: patient's age, size and location of adenomyoma, presence of endometriosis and adenomyosis, past gynecologic treatment, symptoms, diagnostic imaging, surgical intervention, alternative/adjuvant treatment, associated malignancy, and follow up. RESULTS: Sixty-seven studies with 85 patients were included. Pain was the most frequent symptom (69.5%). Among diagnostic examinations, ultrasonography was used in 60 out of 81 reported cases, with several radiologic features described. EA was located inside the pelvis in 77.6% of patients. Adnexa were the most frequent site of the disease (24, 28.2%). History of endometriosis or adenomyosis was described in 35 patients (35, 41.2%). Uterine tissue morcellation was reported in 6 of the 85 patients (7.1%). Associated malignancy was detected in 9 out of 85 patients with available data (10.6%). There were two recurrences of disease. CONCLUSION: Specific imaging features of EA are yet to be described in the literature. History of endometriosis and adenomyosis or uterine tissue morcellation may be suggestive of EA. Histologic examination can give a definitive diagnosis and exclude malignant transformation.

Imaging update on gallbladder adenomyomatosis and its mimics.

Radiologists across many imaging modalities commonly encounter gallbladder adenomyomatosis. The classic imaging appearances of gallbladder adenomyomatosis are well described and confirm benignity. However, in clinical practice, adenomyomatosis can be challenging to differentiate from other gallbladder pathologies that require cholecystectomy. In this article, we describe the common and uncommon appearances of gallbladder adenomyomatosis on multimodality imaging, helping differentiate adenomyomatosis from non-benign gallbladder abnormalities. Accurately differentiating adenomyomatosis from its mimics provides the surgical team with important clinical and surgical management information, improving patient outcomes.

Adenomyoma recurrence 7 years after laparoscopic supracervical hysterectomy: A case report and literature review.

RATIONALE: Adenomyosis, a gynecological condition characterized by endometrial tissue within the uterine myometrium, often leads to menstrual pain and heavy bleeding, significantly affecting the quality of life. The primary treatment for adenomyosis and leiomyomas is hysterectomy. However, in rare instances, these conditions can recur in the cervical stump following a hysterectomy.Here, we present a case of cervical adenomyoma development after a prior laparoscopic supracervical hysterectomy. PATIENT CONCERNS: A 47-year-old woman sought medical attention due to increased vaginal bleeding. DIAGNOSES: She had undergone a laparoscopic supracervical hysterectomy 7 years earlier to address uterine myoma and adenomyosis. Just 1 month posthysterectomy, a pelvic ultrasound revealed the presence of a cervical stump measuring approximately 4.0 × 4.0 cm. Subsequent follow-up ultrasounds documented the gradual growth of the cervical mass. Two years ago, a recurrent myoma was identified, and the patient experienced intermittent vaginal bleeding. Over 7 years, the cervical mass increased from 4 to 7 cm. Preadmission pelvic ultrasonography confirmed the existence of cervical adenomyoma measuring 7 × 6 cm. INTERVENTIONS: Consequently, the patient underwent a laparoscopic trachelectomy. Intraoperatively, an enlarged cervix, approximately 7 × 6 cm in size, containing adenomyoma was observed. A gross examination of the specimen indicated hypertrophic muscle tissue and hemorrhagic foci. Subsequent histopathological examination confirmed the presence of adenomyoma. OUTCOMES: Remarkably, the patient exhibited no recurrence over the subsequent 8 months. LESSONS: The case presented here highlights the potential occurrence of cervical adenomyoma following a supracervical hysterectomy. Management options include hormone therapy and surgical excision. Furthermore, annual follow-up comprising ultrasound and pap smear evaluations is recommended for patients with supracervical hysterectomies to detect and address possible recurrences.

Ileocolic Intussusception in Infancy is not Always Idiopathic - Adenomyoma as the Leading Point.

BACKGROUND Intussusception is a frequent abdominal emergency in infancy, requiring immediate diagnosis and therapeutic intervention. In approximately 90% of cases, intussusception seems to be idiopathic. There has been a reported association of intussusception with lymphoid hyperplasia of Peyer patches in the terminal ileum, possibly acting as the triggering factor. Clinical presentation varies substantially, while the etiology seems idiopathic in most reported cases. CASE REPORT This case describes a previously healthy 2-month-old girl who presented with an episode of non-bilious vomiting and deterioration during the 12 hours preceding the visit. Abdominal ultrasonography revealed the typical target sign in the right iliac fossa, without visible peristalsis, confirming the diagnosis of intussusception. Failure of non-surgical reduction led to emergency laparotomy with the working diagnosis of intussusception due to Meckel's diverticulum. However, laparotomy instead revealed an adenomyoma of the small intestine, a rare benign tumor-like lesion, as the pathological lead point. CONCLUSIONS This case is interesting for 2 distinct reasons. Not only does it underline the need to maintain a high index of suspicion for triggering factors, even in patients within atypically affected age groups, but it also adds to the remarkably limited selection of reported adenomyomas of the small intestine acting as the pathological lead point for intussusception. In this case report, we aspire to emphasize that especially in patients outside the most affected age group, pediatric surgeons should remain aware of the possibility of adenomyoma as a pathological lead point.

Ultrasound diagnosis of the small intestinal adenomyoma in children.

AIM: Adenomyoma is an exceptionally rare hamartoma in the small intestine. Few data have been reported on the features of this rare disease. The aim of this study was to describe the ultrasound (US) characteristics of small intestinal adenomyomas. Material and methods: This retrospective study analyzed the clinical features and US data of 15 pediatric patients diagnosed as small intestinal adenomyomas in the age range between 1 day to 12 years in our hospital during 2014-2021. RESULTS: The clinical manifestations of all the small intestinal adenomyomas were abdominal pain, vomiting or/and hemafecia. The small intestinal adenomyoma usually acted as the lead point of secondary intussusception. They were identified in the ileum (n=11), jejunum (n=2), and Meckel's diverticulum (n=2). The diagnostic accuracy (the concordance rate between US diagnosis and pathological diagnosis) of small intestinal adenomyoma was 73.3%. The small intestinal adenomyoma had approximately 1.0-3.0 cm, were typically located in the submucosal region, had the basal part wide and without a pedicle, and its boundaries were clear. The mass protruded into the intestinal cavity, and showed oval hypoechoic polycystic echo nodules, containing multiple small quasi-circular or irregular cysts of different sizes surrounded by solid hypoechoic mosaic areas. The color Doppler US showed in the solid hypoechoic areas of the mass abundant or sparse blood flow signals.Conclusions The US findings of small intestinal adenomyomas in children are characteristic, and US is valuable in the identification of intestinal adenomyomas in children.

Adenomyoma of the small intestine in children: a 12-year experience in a tertiary referral center.

BACKGROUND: Adenomyoma of the small intestine is rare in children and the clinical characteristics is not clear. The study was to document the clinical characteristics and treatment of children with adenomyoma of the small intestine. METHODS: A retrospective study was conducted in children with intestinal adenomyoma from 2010 to 2022. We recorded age, gender, symptoms, location, tumour size and treatment options. RESULTS: Thirteen patients with adenomyoma of the small bowel were included. The median age was 20 months with a male-to-female ratio of 10:3 and more than half of the patients were younger than 2 years old. The mean tumour size was 2.0 cm. The lesion was found accidentally in one patient, and the others presented with symptoms of intussusception. A pathological lead point was found on ultrasound in seven patients. All tumours were located in the ileum, ranging from 24 to 260 cm proximal to the ileocecal valve. The tumour was found in an antimesenteric site in eight patients. Three patients suffered intestinal necrosis, and segmental resection of the ileum was performed. Three patients without intestinal necrosis underwent tumour rection, while intestinal resection and anastomosis were performed in the remaining seven. All patients recovered well except one, who developed intussusception 7 days after surgery; that patient underwent surgery and recovered uneventfully. CONCLUSIONS: Adenomyoma of the small intestine has a male predominance in children and intussusception is a common presentation. The ultrasound feature is a mass of mixed echogenicity containing several small cystic areas. Surgery is the primary treatment option and the procedure should be chosen based on intraoperative findings.

The typical polypoid adenomyoma is a special form of endometrial polyp: a case-controlled study with a large sample size.

PURPOSE: To investigate clinicopathological differences between typical endometrial polypoid adenomyomas (TPAs) and endometrial polyps (EPs) and to determine the risk factors and recurrence of TPA and further clarify the pathogenesis and treatment of TPA. METHODS: We reviewed the medical records of 488 women with TPA and 500 women with EP. Then, we analyzed the clinical features and manifestations, ultrasonic manifestations, hysteroscopic morphology, and pathological results. In addition, 360 cases of TPA and 367 cases of EP were followed up for 22-77 months and the risk factors TPA recurrence were assessed. RESULTS: We detected significant differences in age, menopausal status, body mass index (BMI), the number of pregnancies, and parity between the two groups (P < 0.05). Hysteroscopy revealed that the incidence of polyps > 3 cm in diameter and multiple polyps in the TPA group was significantly higher than that in the EP group (P < 0.01). In addition, the rate of recurrence in the TPA group was significantly higher than that in the EP group (P < 0.05). Over three pregnancies, menopause, curettage, and the application of polyp clamps were all identified as independent risk factors for the recurrence of TPA (P < 0.05). CONCLUSION: In addition to high estrogen levels, endometrial injury was identified as the main contributor to TPA pathogenesis. Hysteroscopic electrotomy was identified as the preferential treatment for TPA to avoid recurrence, especially in women with risk factors. Increasing the depth of ablation may prevent the recurrence of TPA more efficiently.

Surgical treatment of a rare case of atypical polypoid adenomyoma of the uterus in a menopausal patient: a case report.

Atypical polypoid adenomyoma is a rare benign tumor of the uterus that usually affects women of reproductive age and has an increased risk of progression into endometrial cancer. The pathogenetic mechanism has not been completely clarified. Due to the rarity of the tumor, current experience regarding the diagnostic and therapeutic approach is limited. For menopausal patients, hysterectomy seems to be the main treatment option. Our case concerns an asymptomatic menopausal patient with a vaginal delivery in her obstetric history and no hereditary history of gynecological cancer who came to the outpatient clinic for a gynecological examination. Transvaginal ultrasound revealed the presence of a large, round solid mass with increased vascularity within the endometrial cavity. A diagnostic dilation and curettage of the endometrium was performed. Histological examination of the endometrial biopsy showed an atypical polypoid adenomyoma, and it was decided to perform a total abdominal hysterectomy with bilateral adnexectomy. Histological examination of the surgical specimen of the uterus revealed no residual disease, no coexisting foci of atypical endometrial hyperplasia or endometrial cancer. The postoperative course was uneventful. The patient remains to this day under regular follow-up. The present case report highlights the significant difficulties involved in the preoperative diagnosis of atypical polypoid adenomyoma of the uterus and the difficult differential diagnosis from atypical endometrial hyperplasia and endometrial cancer, particularly in menopausal patients. At the same time, it is pointed out that despite its rarity, the early diagnosis of atypical polypoid adenomyoma, especially in young women, must be the main concern of the modern gynaecologist, in order to design the optimal treatment aimed at preserving fertility while avoiding the risk of recurrence of damage or malignant progression into endometrial cancer.

Adenomyoma of the ampulla of Vater mimicking malignancy: A case report and literature review.

RATIONALE: Adenomyoma is a rare reactive, hamartomatous benign tumor-like lesion. Although adenomyoma can occur anywhere in the gastrointestinal tract, including the gallbladder, stomach, duodenum, and jejunum, it is very rarely observed in the extrahepatic bile duct and ampulla of Vater (AOV). The preoperative accurate diagnosis of adenomyoma of the Vaterian system, including the AOV and common bile duct, is significant to appropriate patient management. However, discriminating between benign and malignancy is highly challenging. Patients are frequently mistaken as having periampullary malignancy, thereby leading to unnecessary extensive surgical resection with a high risk of complications. PATIENT CONCERNS: A 47-year-old woman visited a local hospital owing to epigastric and right upper-quadrant abdominal pain for 2 days. DIAGNOSES: Abdominal ultrasonography performed in the local hospital revealed suspicious of a distal common bile duct malignancy. She was transferred to our hospital for further evaluation and management. INTERVENTIONS: After consulting with the patient, a multidisciplinary team, including a gastroenterologist, finally decided to perform surgery under the impression of an ampullary malignancy, and pylorus-preserving pancreatoduodenectomy was performed without any complications. She was histopathologically diagnosed with an adenomyoma of the AOV. OUTCOMES: At the 5-year follow-up, she was well and did not develop further symptoms or complications. LESSONS: Although adenomyoma is very rare, it should be included in the differential diagnosis of mass-like lesions of the AOV to avoid unnecessary surgeries.

Laparoscopic intervention for solid pelvic tumours in Mayer-Rokitansky-Küster-Hauser syndrome: a case of bilateral uterine adenomyomas of the rudimentary uterus.

Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome, a condition caused by Müllerian anomalies, is characterised by congenital vaginal aplasia and a rudimentary uterus. Case reports concerning uterine fibroids associated with MRKH syndrome are limited, and differentiating between uterine fibroids and ovarian solid tumours prior to surgical intervention is often challenging. Here, we present the case of a patient with MRKH syndrome and asymptomatic bilateral pelvic solid tumours located close to both ovaries. Based on intraoperative and histopathological findings, the tumours were diagnosed as adenomyomas of the rudimentary uterus. This is the first reported case of a uterine adenomyoma associated with MRKH syndrome. Moreover, our report highlights the fact that diagnostic laparoscopy is a valuable method to evaluate pelvic tumours in MRKH syndrome.

Endometrioid Adenocarcinoma Resembling Cutaneous Pilomatrix Carcinoma: A Case Report of an Aggressive Neoplasm in a Young Woman With Diffusely Aberrant Beta-catenin Expression and Associated Morular Metaplasia and Atypical Polypoid Adenomyoma-type Change.

Endometrioid carcinoma with histopathologic resemblance to cutaneous pilomatrix carcinoma with mutations in the gene encoding beta-catenin, CTNNB1 are rare. There are minimal numbers of reports of high-grade tumors with this divergent differentiation in the literature. We report the case of a 29-yr-old female with an unusual presentation of endometrial cancer with overall histologic appearance indicative of a recently reported aggressive subtype of Federation of Gynecology and Obstetrics (FIGO) IVB grade 3 endometrioid carcinoma with features resembling cutaneous pilomatrix carcinoma. She was treated with a primary chemotherapy regimen with an initial significant response to treatment before developing symptomatic brain metastasis for which she underwent whole-brain radiotherapy. We discuss the unusual histologic and radiologic presentation as well as her individual management throughout this case report. The apparent association with morular metaplasia and atypical polypoid adenomyoma suggests that this rare carcinoma is within a spectrum of lesions associated with aberrant beta-catenin expression/beta-catenin mutation. Its aggressive nature highlights the importance of early recognition of this rare lesion.

When Aunt Minnie turns out to be a Zebra: distal bile duct adenomyoma stimulating pancreas head tumor.

A 55-year-old female patient with a history of ethyl and nicotine abuse presented with chronic diarrhoea, significant weight loss and abnormal liver tests. Ultrasound examination revealed dilatation of the bile ducts and computed tomography scan with IV contrast further established simultaneous dilatation of the common bile duct and pancreatic duct (double duct sign). The dilatation abruptly stopped at the level of the pancreatic head which demonstrated a small irregular hypovascular zone (1.2 cm), suspected for malignancy. The following week, a radical pancreaticoduodenectomy was performed. Anatomopathological analysis revealed an adenomyoma (12 mm) located distal to the common bile duct, without arguments for malignancy.

Analysis of Convolutional Neural Network Segmentation Algorithm of Adenomyoma.

Adenomoma is a common disease occurring in the female uterus. The symptoms and pain of adenomoma seriously troubled the physical and mental health of contemporary women. However, because of the significant advantages of nondestructive and low price, ultrasound examination is used as the main imaging method for clinical diagnosis of gynecological diseases at the present stage and is often used in the initial screening and postoperative diagnosis and treatment of uterine diseases. Imaging provides a very rich information in the medical diagnosis of tumor and is a very important basis for the disease diagnosis and treatment at this stage. Ultrasound images are different from medical images such as X-ray and MRI. Because of the characteristics of imaging principles and noise interference, ultrasound images need to rely on rich clinical experience of doctors in the process of disease diseases, which increases the difficulty and work burden of doctors to some extent. Therefore, the project aims to study the deep learning segmentation method suitable for ultrasonic images. Combined with the Deeplab network in the convolutional neural network, comparing the results of the FCN network, and then finding that the Deeplab network has obvious advantages as an image segmentation model of uterine adenomyoma. In clinical practice, it can reduce the work burden of doctors and try in the direction of uterine adenomyomas ultrasound image segmentation, to fill the gap in this field.

Extrauterine adenomyoma of the lesser omentum: A case report and review of the literature.

RATIONALE: The extrauterine adenomyoma is rare and it is extremely rare outside the pelvic cavity. Herein, we reported the first case of a single extrauterine adenomyoma occurring in the lesser omentum. PATIENTS CONCERNS: This case involved a 55-year-old woman who had undergone subtotal gastrectomy and omentectomy for gastric carcinoma. During postoperational pathological examination, 1 lymph node-like mass was coincidentally found in the lesser omentum. The patient had a history of hysterectomy for uterine leiomyoma 8 years ago. DIAGNOSES: The resected 17 "lymph nodes" from the lesser omentum were routinely checked for possible metastasis of gastric carcinoma. One of lymph node-like mass was microscopically showed that it was composed of benign smooth muscle components, endometrial glands and stroma by HE staining. Therefore, adenomyoma was initially considered. INTERVENTIONS: The lymph node-like mass was removed together with the lesser omentum during the subtotal gastrectomy and omentectomy for gastric carcinoma. No special intervention was performed for the adenomyoma. OUTCOMES: Immunohistochemical staining confirmed that smooth muscle tissue was diffusely and strongly positive for Desmin, smooth muscle actin, estrogen receptor, and progesterone receptor, and negative for CD117, Dog-1, S100, and CD34. Endometrial glands and stroma were positive for estrogen receptor and progesterone receptor, and the endometrium interstitium was also positive for CD10. The final diagnosis of extrauterine adenomyoma occurring in the lesser omentum was established. LESSONS: So far, to the best of our knowledge, total 53 cases of extrauterine adenomyoma have been reported in 45 English reports. The most common location for a single mass was pelvic cavity (37 cases), but rarely outside the pelvic cavity. This is the first case of a single extrauterine adenomyoma occurring in the lesser omentum.

Surgical techniques for excision of juvenile cystic adenomyoma.

OBJECTIVE: To review causes of pelvic pain among adolescents and discuss surgical techniques for safe and effective resection of juvenile cystic adenomyomas. DESIGN: Case report. SETTING: Academic medical center. PATIENTS: We present a 16-year-old patient with chronic pelvic pain and ultrasound evidence of a 2.4 cm adenomyoma. The lesion was thought specifically to represent a juvenile cystic adenomyoma, defined as a cystic lesion >1 cm occurring in women younger than 30 years with severe dysmenorrhea that is distinct from the uterine cavity and surrounded by hypertrophic myometrium. INTERVENTION: Given minimal relief from medical therapy and high suspicion for coexistent endometriosis, our patient elected to undergo laparoscopic resection of adenomyoma and excision of pelvic lesions. MAIN OUTCOME MEASURES: Preoperative considerations discussed in this video include imaging to identify the location of the lesion and adjacent structures, such as the uterine vessels, discontinuation of gonadotropin-releasing hormone agonist for adequate intraoperative visualization, and the high likelihood of encountering endometriosis at operation. RESULTS: We review the following surgical techniques: maximize visualization with the use of a uterine manipulator and temporary oophoropexy, optimize hemostasis via temporary uterine artery ligation and control of collateral blood vessels, complete ureterolysis, meticulous enucleation of adenomyoma, and excision of coexistent endometriotic lesions. Surgical findings demonstrated a 2 cm lesion along the left lower uterine segment and red-brown lesions along bilateral ovarian fossa, pathologically confirmed as adenomyoma and superficial endometriosis, respectively. CONCLUSION: This video presents strategies for safe and effective adenomyoma resection and treatment of refractory chronic pelvic pain in an adolescent.

Fertility-sparing surgery for diffuse adenomyosis: a narrated, stepwise approach to the Osada procedure.

OBJECTIVE: To equip reproductive surgeons with an approach to the Osada procedure and critical prophylactic hemostatic measures that optimize perioperative outcomes. DESIGN: Stepwise demonstration of the Osada procedure with narrated video footage. SETTING: Definitive management of symptomatic adenomyosis requires hysterectomy. However, adenomyomectomy can improve symptoms and restore anatomy while maintaining fertility potential. Limited but comparable perioperative outcomes exist for minimally invasive methods of adenomyomectomy, and most involve resection of focal, not diffuse, adenomyosis. Among the literature involving resection of diffuse adenomyosis using minimally invasive methods, relatively small volumes of resected tissue are reported and none include obstetric outcomes. Most published reports for excision of diffuse adenomyosis involve laparotomic resection, likely because of specific intraoperative challenges curtailed by this approach. In response, a laparoscopic-assisted laparotomic approach was developed in 2011 by Dr. Hisao Osada, a reproductive surgeon in Japan. This procedure involves aggressive excision of adenomyotic tissue with prophylactic hemostatic techniques and subsequent uterine wall reconstruction using a triple-flap method. Compared with other excisional methods for diffuse adenomyomectomy, the Osada procedure has the best reported obstetric outcomes. PATIENT(S): A 37-year-old nulliparous female presented with pelvic pain, bulk symptoms, abnormal uterine bleeding, and infertility. Physical examination demonstrated a 20-week, bulky uterus with limited bimanual mobility. Her endometrial cavity was inaccessible because of marked anatomic distortion. Magnetic resonance imaging revealed marked abnormality of her endometrial contour because of a 15 cm adenomyoma with diffuse adenomyomatous tissue in the posterior uterine compartment. Prior interventions included a trial of combined hormonal contraceptive, leuprolide acetate, and tranexamic acid. She was interested in fertility-sparing adenomyomectomy to address symptoms and fertility potential and chose to proceed with the Osada procedure. She was optimized medically with oral and parenteral iron therapy to bring her hemoglobin from 55-111 g/L preoperatively. Institutional review board approval and informed consent from the patient were obtained. INTERVENTION(S): The Osada procedure was performed using the following 8 surgical steps: Systemic administration of tranexamic acid was also administered intraoperatively. MAIN OUTCOME MEASURE(S): Perioperative blood loss, anatomic normalization, symptom remediation, and maintenance of fertility potential. RESULTS: Perioperative blood loss was minimal, 469 g of adenomyotic tissue was extracted, and discharge was on postoperative day 2 without any complications. Three months later, cyclic pain and bleeding had improved markedly, ultrasound confirmed Doppler flow throughout the uterus, hysterosalpingogram demonstrated a nonobliterated endometrial cavity and tubal patency, and magnetic resonance imaging confirmed normalized uterine dimensions measuring 11 × 7 cm from 19 × 10 cm. Most literature supports waiting at least 6-12 months and until demonstration of normalized uterine blood flow in the operated area before attempting conception. CONCLUSION: Fertility-sparing excision of diffuse adenomyosis can be achieved safely using the Osada procedure, following the 8 discrete steps demonstrated in this video. Reproductive surgeons can reference this video to teach and maintain this important procedure.

Value of Transabdominal Combined Transvaginal Color Doppler Ultrasonography in the Distinguish between Uterine Adenomyoma and Uterine Fibroids.

Objective: To investigate the value of transabdominal combined transvaginal color Doppler ultrasonography in the diagnosis of uterine adenomyoma. Methods: A total of 80 patients with suspected uterine adenomyoma in our hospital from January 2019 to December 2021 were selected as the study subjects. All of them were examined by transabdominal color Doppler ultrasound (TA-CDUS) and transvaginal color Doppler ultrasound (TV-CDUS), and the postoperative pathological examination results were taken as the gold standard to analyze the diagnostic efficacy of different examination methods for uterine adenomyoma. Results: By postoperative pathological biopsy, 46 cases (57.50%) were diagnosed as positive and 34 cases (42.50%) were diagnosed as negative, including 29 cases of uterine adenomyoma and 5 other cases. The sensitivity, accuracy, and negative predictive value of TA-CDUS combined with TV-CDUS in the diagnosis of adenomyoma were higher than those of TA-CDUS (P < 0.05), and the Kappa value between TA-CDUS and pathological diagnosis was 0.923, which was higher than the 0.615 between TV-CDUS and pathological diagnosis. TA-CDUS combined with TV-CDUS showed that there were significant differences in the distribution of Adier blood flow grades between patients with uterine adenomyoma and uterine fibroids (P < 0.05), and the Adier blood flow grades of patients with uterine adenomyoma were mainly grade 0 and grade I; and the resistance index (RI), peak systolic velocity (Vs), and pulsatile index (PI) in patients with uterine adenomyoma were higher than those in patients with uterine fibroids (P < 0.05). Conclusion: Compared with TA-CDUS, TA-CDUS combined with TV-CDUS is more sensitive and accurate in the diagnosis of uterine adenomyoma and has a good consistency with pathological diagnosis results. Attention should be paid to the blood flow parameter values in the differential diagnosis of uterine fibroids.
