INTRODUCTION: Pelvic floor ultrasound plays a major role in urogynecologic diagnostics. Using 3D ultrasound we can identify integrity of levator ani and measure hiatal area in the axial plane. The main goal of our study was to measure hiatal area on Valsalva in a cohort of urogynecological patients. Furthermore, we aimed to correlate hiatal area with urogynecological symptoms, levator integrity and evaluate cut-off values for pelvic organ prolapse. MATERIALS AND METHODS: In a retrospective analysis, we included 246 patients seen for urogynecological problems in our tertiary urogynecological unit...

BACKGROUND: Extralevator abdominoperineal excision for distal rectal cancers involves cylindrical excision of the mesorectum with wide division of the levator ani muscles. Although this technique has been shown to decrease local cancer recurrence and improve survival, it leaves the patient with a considerable pelvic floor defect that may require reconstruction. OBJECTIVE: We developed an innovative technique of robotic extralevator abdominoperineal excision combined with robotic harvest of the rectus abdominis muscle flap for immediate reconstruction of the pelvic floor defect...

PURPOSE: Extra-levator abdominoperineal excision for rectal cancer includes resection of the levator ani muscle and therefore makes pelvic reconstruction advisable. The aim of our study was to evaluate morphologic and functional long-term results of pelvic floor augmentation with porcine dermal collagen mesh by dynamic magnetic resonance imaging and clinical examination. METHODS: Twenty consecutive patients underwent perineal reconstruction with porcine dermal collagen mesh following extra-levator abdominoperineal excision for primary rectal adenocarcinoma with curative intent between 2009 and 2012...

INTRODUCTION: The natural history of pelvic organ prolapse (POP) is poorly understood. We investigated the prevalence and risk factors of postnatal POP in premenopausal primiparous women and the associated effect of mode of delivery. METHODS: We conducted a prospective cohort study in a tertiary teaching hospital attending 9,000 deliveries annually. Collagen-diseases history and clinical assessment was performed in 202 primiparae at ≥ 1 year postnatally. Assessment included Pelvic Organ Prolapse Quantification (POP-Q) system, Beighton mobility score, 2/3D-transperineal ultrasound (US) and quantification of collagen type III levels...

Primary perineal hernia is a rare clinical condition wherein herniation of viscera occurs through pelvic diaphragm. They are usually mistaken for sciatic hernia, rectal prolapse or other diseases in the perineum. Correct identification of the type of hernia by imaging is crucial for planning treatment. We present a case of primary posterior herniation of urinary bladder and rectal wall through levator ani repaired laparoscopically using a mesh repair.

UNLABELLED: WHAT'S KNOWN ON THE SUBJECT? AND WHAT DOES THE STUDY ADD?: Several studies in the paediatric literature have characterized the pelvic musculoskeletal anatomy of infants and children with bladder exstrophy using MRI and three-dimensional CT. The pelvic floor anatomy of female patients with bladder exstrophy who have undergone somatic growth and puberty is less well described. This study uses MRI to characterize comprehensively the pelvic anatomy of postpubertal females with classic bladder exstrophy by measuring 15 pelvic floor variables previously described in younger children with bladder exstrophy...

OBJECTIVE: Little data exist about the optimal management of the rare coccygeal hernia. A novel method of repair is reported. METHODS: A 46-year-old woman presented with a symptomatic coccygeal hernia after resection of the coccyx for a tumour. She had previously been reconstructed with an on-lay polytetrafluorethylene (PTFE) mesh but subsequently developed a hernia. A de-epithelialised vertical rectus abdominis musculocutaneous flap was elevated and passed through the hernia defect...

REVIEW
Peter L Dwyer
Surgery is an evolving science in the attempt to make surgical procedures more effective, safer, and less invasive. Recurrence and subsequent re-operation for stress incontinence and prolapse has been reported to be necessary in one of three patients, so there is a need for improvement [1]. In reconstructive pelvic surgery (RPS), the use of biological and synthetic grafts for the transabdominal and transvaginal treatment of pelvic organ prolapse (POP) or stress urinary incontinence (SI) has improved long-term support and function after surgery...

Cases of perineal hernias in three cats are described. All the cats were male (2 castrated, 1 intact). The hernias were situated between the external anal sphincter and the levator ani muscle. The hernial sac contained a dilated rectum filled with fecal content (2 cats) as well as a small amount of retroperitoneal fatty tissue (2 cats) and urinary bladder (1 cat). A standard perineal herniorrhaphy in two cats, and herniorrhaphy via elevation of the internal obturator muscle in one cat were performed. No recurrence of the problem was observed in two cats during 9 months following the surgery...

Sigmoid resection is indicated in the treatment of complete rectal prolapse (CRP) in patients with prolonged colorectal transit time (CTT). Its use however has been limited due to fear of anastomotic leakage. This study challenges the current practice of dividing the mesorectum by prospectively evaluating the impact of sparing the superior rectal artery (SRA) on leak rates after laparoscopic sigmoid resection (LSR) for CRP. During 30 months data on 33 selected patients with CRP were prospectively collected...

PURPOSE: Patients with symptomatic pelvic organ prolapse often have multifocal pelvic floor defects that are not always evident of physical examination. In this study, dynamic magnetic resonance imaging of symptomatic patients with pelvic floor prolapse demonstrated unsuspected levator ani hernia. This study was designed to identify any specific symptoms and/or physical findings associated with these hernias. METHODS: Eighty consecutive patients with pelvic organ prolapse, fecal and/or urinary incontinence, or chronic constipation received standardized questionnaires, physical examination, and dynamic magnetic resonance imaging...

The muscle changes related to pelvic floor disorders are poorly understood. We conducted an anatomical and histological study of the perineum of the normal mouse and of a transgenic mouse strain deficient in urokinase-type plasminogen activator (uPA-/-) that was previously reported to develop a high incidence of rectal prolapse. We could clearly identify the iliococcygeus (ILC) and pubococcygeus (PC) muscles and anal (SPA) and urethral (SPU) sphincters in male and female mice. The bulbocavernosus (BC), ischiocavernosus (ISC) and levator ani (LA) muscles could be found only in male mice...

A sexually intact, male Chihuahua and a spayed female poodle were presented with left perineal masses. The masses were identified as perineal hernias by rectal palpation. Surgical exploration of the perineal region in each dog revealed retroperitoneal fat protruding between the sacrotuberous ligament and the coccygeus muscle (sciatic perineal hernia). The hernias were repaired using modifications of the standard or internal obturator flap herniorrhaphies. The levator ani muscle was grossly and histologically normal in the Chihuahua and grossly normal in the poodle...
