A 47-year-old female presented to clinic with a 5-year history of a left buttock mass. The patient's hemoglobin was low (9.7 g/dL); laboratory analysis was otherwise unremarkable. Ultrasound of the left gluteal region demonstrated a heterogeneous vascular solid lesion. Magnetic resonance and computed tomography imaging showed an enhancing mass extending from the left ischioanal fossa through the levator ani muscle into the pelvis. Biopsy revealed bland-appearing spindle-shaped cells positive for estrogen and progesterone receptors, consistent with an aggressive angiomyxoma...

BACKGROUND: Stress urinary incontinence is a significant problem in young female athletes, but the pathophysiology remains unclear because of the limited knowledge of the pelvic floor support function and limited capability of currently available assessment tools. The aim of our study is to develop an advanced computer modeling tool to better understand the dynamics of the internal pelvic floor during highly transient athletic activities. METHODS: Apelvic model was developed based on high-resolution MRI scans of a healthy nulliparous young female...

INTRODUCTION: Vaginal delivery can lead to pelvic floor disorders. Many authors have described pelvic floor injuries that can predict future defects such as urinary incontinence and pelvic organ prolapse. We propose the assessment of urinary stress incontinence and its association with levator ani muscle (LAM) microtrauma (>20% in the levator hiatus area during Valsalva) and macrotraumas (avulsion) identified by 3/4D transperineal ultrasound (3D-TpUS) 36 months post-partum. MATERIALS AND METHODS: This was a prospective observational study including 168 nulliparous women...

BACKGROUND AND AIMS: Food is the most important synchronizer of gastrointestinal motility and secretion. Many patients with functional bowel or anorectal disorders complain of fecal urge and stool output after eating. PATIENTS AND METHODS: In this prospective observational study, 408 consecutive outpatients with functional bowel and/or anorectal disorders (74% female, 50.2±15.6 years, 24.8±5.0 kg/m²) filled Rome III questionnaires. Depression and anxiety scores, a physiological evaluation (total and segmental colonic transit time, colonic transit response to eating using a standard 1000 kcal test meal, and anorectal manometry), were measured...

AIMS: To characterize the nature and function of the levator ani muscle innervation pathways and to perform a comprehensive three-dimensional reconstruction of female pelvic innervation. METHODS: A computer-assisted anatomical dissection protocol was applied to seven female human fetuses, after approval from the national biomedicine agency. Specimens were serially sectioned and immunostained for overall (antibody against protein S100), somatic (antibody against peripheral myelin protein 22), adrenergic (antibody against tyrosine hydroxylase), cholinergic (antibody against vesicular acetylcholine transferase), and nitrergic (antibody against the neural isoform of nitric oxide synthase) nerve fibers...

The efficacy of laparoscopic total mesorectum excision (TME) has been confirmed by many clinical trials and guidelines. But two issues on laparoscopic TME are still questioned, including the integrity of specimen membrane of TME and the incidence of postoperative sexual dysfunction. According to my experiences and the primary results of the multicenter clinical trial (LASRE, clinicaltrials.gov identifier: NCT01899547) conducted by me, the integrity of the specimen membrane of laparoscopic TME is not inferior to the open TME...

BACKGROUND: Sciatica has been classically described as pain in the back and hip with radiation in the leg along the distribution of the sciatic nerve, secondary to compression or irritation of the sciatic nerve. Spinal abnormality being the most common etiology, is one of the most common indications for MRI of the lumbosacral spine. Here we describe imaging findings secondary to a supralevator perianal abscess causing irritation of the sciatic nerve, which was diagnosed on MRI of the lumbosacral spine...

Adil E Bharucha, Tae Hee Lee
Although pelvic pain is a symptom of several structural anorectal and pelvic disorders (eg, anal fissure, endometriosis, and pelvic inflammatory disease), this comprehensive review will focus on the 3 most common nonstructural, or functional, disorders associated with pelvic pain: functional anorectal pain (ie, levator ani syndrome, unspecified anorectal pain, and proctalgia fugax), interstitial cystitis/bladder pain syndrome, and chronic prostatitis/chronic pelvic pain syndrome. The first 2 conditions occur in both sexes, while the latter occurs only in men...

INTRODUCTION AND HYPOTHESIS: Pelvic floor muscle rehabilitation is a widely utilized, but often challenging therapy for pelvic floor disorders, which are prevalent in older women. Regimens involving the use of appendicular muscles, such as the obturator internus (OI), have been developed for strengthening of the levator ani muscle (LAM). However, changes that lead to potential dysfunction of these alternative targets in older women are not well known. We hypothesized that aging negatively impacts OI architecture, the main determinant of muscle function, and intramuscular extracellular matrix (ECM), paralleling age-related alterations in LAM...

High intensity focused ultrasound (HIFU) is a minimally invasive treatment option that might be considered in the management of localized prostate cancer. It is a well-tolerated treatment with few minor urologic complications and no major toxicities. In this paper, we report to our knowledge the first case of levator ani necrosis in a patient treated with HIFU, manifesting as sturdy perineal pain, which took years of NSAID intake and serial MRIs to demonstrate partial improvement. Therefore, we regard HIFU as a serious potential treatment option that still requires longer follow-up data before its approval in the personalized treatment panel of prostate cancer...

OBJECTIVES: Caudal distension of female pelvic floor is common and results in perineal descent and a caudally curved hiatus (so called 'warping'). All the available ultrasound techniques to date however aim to reconstruct the pelvic floor using linear techniques (flat plane reconstruction). We aimed to evaluate the feasibility, reproducibility and potential usefulness of a new 3D technique, capable of reconstructing a curved plane of the levator hiatus. METHODS: We recruited a group of primiparous women to perform a 3D/4D transperineal ultrasound 3-6 months after delivery...
