Karicha Mairaing, Kuan-Gen Huang
STUDY OBJECTIVE: To demonstrate a minimal invasive surgical (MIS) technique for curative excision of extensive secondary disseminated peritoneal leiomyomatosis (DPL). SETTING: In MIS, the myoma has to be divided into small fragments for piecemeal retrieval through a small incision [1], a widely used technique is morcellation (confined or unconfined) [2]. Disseminated peritoneal leiomyomatosis (DPL) is a rare sequel following laparoscopic morcellation. Since this entity is rarely reported, this video demonstrates laparoscopic technique for safe removal of DPL post laparoscopic myomectomy and morcellation...

BACKGROUND: Radiotherapy for cervix cancer is challenging in patients exhibiting large daily changes in the pelvic anatomy, therefore adaptive treatments (ART) have been proposed. The aim of this study was the clinical implementation and subsequent evaluation of plan-of-the-day (POTD)-ART for cervix cancer in supine positioning. The described workflow was based on standard commercial equipment and current quality assurance (QA) methods. MATERIALS AND METHODS: A POTD strategy, which employs a VMAT plan library consisting of an empty bladder plan, a full bladder plan and a motion robust backup plan, was developed...

OBJECTIVES: Correct positioning of the acetabular component is a key factor in minimizing the risk of dislocation after total hip replacement (THR) surgery. A "safe" orientation of the cup is usually defined by 2 angles measured between its geometric axis and the anterior pelvic plane. However, in the current state-of-the-art approach to THR surgery, the intraoperative orientation of the anterior pelvic plane cannot be measured. Even less is known about the functional orientation of the pelvis, which determines the postoperative orientation of the cup during the patient's everyday activities...

BACKGROUND: Injury to the levator ani muscle or pelvic nerves during pregnancy and vaginal delivery are responsible for pelvic floor dysfunction. OBJECTIVE: To demonstrate the presence of smooth muscular cell areas within the levator ani muscle and describe their localization and innervation. STUDY DESIGN: Five female human fetuses were studied after approval from the French Biomedicine Agency. Specimens were serially sectioned and stained by Masson's trichrome and immunostained for striated and smooth muscle, as well as for somatic, adrenergic, cholinergic, and nitriergic nerve fibers...

INTRODUCTION: Cystoceles may cause urethral obstruction by altering the vesicourethral angle. Restoration of normal anatomy after pelvic organ prolapse (POP) repair can relieve this obstruction but may unmask stress urinary incontinence (SUI). The association between the severity of cystocele and developing de novo SUI after prolapse repair, however, is poorly understood. We hypothesized that, in women undergoing prolapse repair, increasing degrees of bladder prolapse would be associated with increasing rates of postoperative de novo SUI...

The purpose of this article is to help the practitioner ensure early diagnosis and response to emergencies in the first trimester by reviewing anatomy of the developing embryo, highlighting the sonographic appearance of common first-trimester emergencies, and discussing key management pathways for treating emergent cases. First-trimester fetal development is a stepwise process that can be challenging to evaluate in the emergency department (ED) setting. This is due, in part, to the complex anatomy of early pregnancy, subtlety of the sonographic findings, and the fact that fewer than half of patients with ectopic pregnancy present with the classic clinical findings of a positive pregnancy test, vaginal bleeding, pelvic pain, and tender adnexa...

BACKGROUND: In plain pelvic X-ray, magnification makes measurement unreliable. The EOS™ (EOS Imaging, Paris France) imaging system is reputed to reproduce patient anatomy exactly, with a lower radiation dose. This, however, has not been assessed according to patient weight, although both magnification and irradiation are known to vary with weight. We therefore conducted a prospective comparative study, to compare: (1) image magnification and (2) radiation dose between the EOS imaging system and plain X-ray...

BACKGROUND AND AIMS: The wear of metal-on-metal hip implants may increase chromium or cobalt ion blood level. This phenomenon may depend among other things on the particularity of spinopelvic anatomy. The effect of pelvic incidence angle on the wear of metal-on-metal hip implants is not known. The objective of the study was to investigate whether such effect does exist. MATERIAL AND METHODS: The pelvic incidence and inclination of acetabular component angles of 89 patients after unilateral metal-on-metal hip replacement were compared with blood level of chromium and cobalt ions using Pearson correlation coefficient...

INTRODUCTION: Density changes occurring during fractionated radiotherapy in the pelvic region may degrade proton dose distributions. The aim of the study was to quantify the dosimetric impact of gas cavities and body outline variations. MATERIAL AND METHODS: Seven patients with locally advanced cervical cancer (LACC) were analyzed through a total of 175 daily cone beam computed tomography (CBCT) scans. Four-beams intensity-modulated proton therapy (IMPT) dose plans were generated targeting the internal target volume (ITV) composed of: primary tumor, elective and pathological nodes...

OBJECTIVE: To evaluate the effects of surgical anatomical correction on lower urinary tract symptoms (LUTS) in patients with a pelvic anterior compartment defect (PACD). METHODS: This prospective study was carried out on 30 women who had stage II-IV PACD. The women were questioned regarding LUTS symptoms such as urgency, urge incontinence, frequency, hesitancy, abnormal emptying, nocturia and dysuria pre and postoperatively. After a 7-month follow up, the comparison of LUTS symptoms with respect to their healing, existence or de novo appearance was performed using the McNemar and Bowner and Wilcoxon signed-rank tests...

Chondrosarcoma is considered as a common primary bone sarcoma. These sarcomas can form large masses without any specific symptoms because there are no barriers in pelvic anatomy to prevent the enlargement of tumors, and can mimic ovarian masses. We present a pelvic chondrosarcoma in a woman aged 37 years who was misdiagnosed as having an ovarian mass due to the limited information obtained from imaging studies. Pelvic chondrosarcoma should be considered in patients who have pelvic masses with solid components...

BACKGROUND: This review focuses on the initial presentation of women who suspect that they are infertile, and how best to assess the anatomy of their uterus and ovaries in order to investigate the cause of their infertility, and potentially improve desired fertility outcomes. This review was undertaken as part of a World Health Organization initiative to assess the evidence available to address guidance for the diagnosis and treatment of infertility within a global context. Providing access to care for infertile women will help to ease the psycho-social burdens, such as ostracization, intimate partner violence and other negative consequences of being involuntarily childless or unable to become pregnant despite desiring a biological child or children...

INTRODUCTION: Magnetic Resonance Imaging (MRI) of adult female pelvis is a well-established tool in the evaluation of utero-ovarian lesions and is often used to supplement ultrasonography. The need for diagnostic surgical intervention has largely been eclipsed with the advent of MRI, which has become the imaging modality of choice for characterization of pelvic masses. AIM: To assess the role of MRI in female pelvic mass lesions and to exploit the tissue characterization capability of MRI...

The aim of this study was to develop a detailed and accessible set of reference images of the normal radiographic anatomy of the digits of the ostrich (Struthio camelus), with emphasis on the metatarsophalangeal joint and its arthrography. The distal excised pelvic limbs of 10 normal ostriches of different ages (ranging from 10 to 365 days of age) obtained from an abattoir were radiographed, and 2 arthrograms were performed. To illustrate the normal radiographic anatomy of the tarsometatarsal bone, 39 images were selected, labelled, and presented along with detailed descriptions and corresponding images of the bony skeleton...

The increased life expectancy, the importance of the prevention in younger age and the role of the pelvic floor disfunction not only in the disease of the third age, but also in the childbearing age, as the influence on the type of delivery, underline the importance of the evaluation of the pelvic floor. The evaluation of pelvic floor is generally clinical, but in the last 2 decades, the use of ultrasound has become a mainstream diagnostic tool in the investigation of female pelvic organ prolapse, urinary and fecal incontinence and defecation disorders, providing an immediate objective confirmation of findings obtained on clinical examination and filling some of the gaps of the urogynecological exam...

BACKGROUND: A knowledge deficit of pelvic anatomy has been noted in obstetrics and gynecology residents. In this article, we introduce an innovative anatomic model that uses readily accessible and reusable materials to simulate and teach anatomic relationships in the female pelvis. INSTRUMENT: Our anatomic model is a reusable and cost-effective modification of an existing pelvic model. We used felt fabric pieces with hook-and-loop fasteners to simulate the pelvic floor, perineum, and surrounding musculature as they attach to corresponding sites on a standard bony pelvis...
