Often, defects will occur in more the one compartment with apical defects contributing primarily to the descent of the anterior or posterior vaginal wall. If the vaginal apex, defined as either the cervix or vaginal cuff after total hysterectomy, is displaced downward, it is referred to as apical prolapse and must be addressed. Apical prolapse procedures may be performed via native tissue repair or with the use of mesh augmentation. Sacrospinous ligament suspension and uterosacral ligament suspension are common native tissue repairs, traditionally performed vaginally to re-support the apex. The uterosacral ligament suspension may also be performed laparoscopically. We review the pathophysiology, clinical presentation, evaluation, pre-operative considerations, surgical techniques, complications, and outcomes of these procedures.

Yoo and Udayan K. Shah 1. Introduction Adenotonsillectomy (T&A) is one of the most commonly performed surgical procedures in children. An estimated 530,000 children undergo tonsillectomies each year in the United States.1 Various instruments are available currently to perform adenotonsillectomy. In Walner et al, monopolar electrocautery was used most often for total tonsillectomy. Monopolar electrocautery alone or in conjunction with the adenoid curette or the microdebrider were the top three instruments.2 In this chapter, we review the currently available technologies for performing T&A in children. We first review indications for T&A before discussing specific technologies and then discuss specific applications of these technologies for T&A. 2. Indications for T&A The indications for tonsillectomy have shifted over the past 40 years. In the early 1970s, close to 90% of tonsillectomy procedures in the United States were performed in response to infections. Current trends in T&A suggest obstructive sleep apnea (OSA) as the indication for tonsillectomy in younger children, ages 0-8 years, while infection is the most common indication in children ages 9-18 years.3 Today, most procedures are performed to treat sleep disordered breathing (SDB), which is defined as a continuum from primary snoring to OSA. This trend reflects not only improved control of the complications of group A streptococcal pharyngitis with antibiotics but also increased rates of childhood obesity, a concomitant and perhaps related factor in the diagnosis of SDB, and a greater awareness of the impact of SDB on children’s educational progress and cognitive development.

Abstract Although laparoscopic surgery or robotic surgery has recently been the main proce- dure adopted for managing benign uterine tumors, abdominal total hysterectomy must still be learned as a basic surgical skill for obstetricians and gynecologists. Total hysterectomy is divided into two types: the extrafascial and intrafascial approaches. Intrafascial hysterectomy, represented by the Aldridge’s method, is a useful and safe procedure for treatment when the patient has no cervical malignancy, including cervical intraepithelial neoplasia. Furthermore, the intrafascial approach is safely performedeveninpatientswithfirm adhesion in the Douglas’s pouch and/or around the uterine cervix due to endometriosis, pelvic inflammatory diseases, or a history of intrapelvic surgery.

  • Chapter One Introduction
    Chapter One Introduction 1.1 Introduction Ultrasound is the term used to describe sound of frequencies above 20 000 Hertz (Hz), beyond the range of human hearing. Frequencies of 1–30 megahertz (MHz) are typical for diagnostic ultrasound. Diagnostic ultrasound imaging depends on the computerized analysis of reflected ultrasound waves, which non-invasively build up fine images of internal body structures. The resolution attainable is higher with shorter wavelengths, with the wavelength being inversely proportional to the frequency. However, the use of high frequencies is limited by their greater attenuation (loss of signal strength) in tissue and thus shorter depth of penetration. For this reason, different ranges of frequency are used for examination of different parts of the body: 3–5 MHz for abdominal areas , 5–10 MHz for small and superficial parts and 10–30 MHz for the skin or the eyes.[Harald Lutz2011]. To form a B-mode image, a source of ultrasound, the transducer, is placed in contact with the skin and short bursts or pulses of ultrasound are sent into the patient. These are directed along narrow beam-shaped paths. As the pulses travel into the tissues of the body, they are reflected and scattered, generating echoes, some of which travel back to the transducer, where they are detected. These echoes are used to form the image. To display each echo in a position corresponding to that of the interface or feature (known as a target) that caused it, the B-mode system needs two pieces of information. These are the range (distance) of the target from the transducer and the 1 direction of the target from the active part of the transducer, i.e.

All these are completed by the ability to manage the immediate and critical situations dynamically and to analyze the diseases interdisciplinarily (e.g. diagnosis, differential diagnosis, appropriate decision among the alternative possibilities of treatment, etc.). A successful surgical intervention requires even more than this. It needs the perfect, aimful and economical coordination of operational movements. The refined technique of the handling and uniting the tissues –in the case of manual skills– is attainable by many practices, and the good surgeon works on the perfection of this technique in his daily operating activities. The most important task in the medical education is to teach the problem-oriented thinking and the needed practical ability. The graduate medical student will notice in a short time that a medical practitioner principally needs the practical knowledge and manual skill in provision for the sick. “The surgical techniques” is a popular subJect. It is a subJect in which the medical students -for the first time- will see the inside of the living and pulsating organism.

The anatomy of the pelvic floor and its fascial components are currently poorly described and misunderstood. This systematic search and review aimed to explore and summarize the current state of knowledge on the fascial anatomy of the pelvic floor in women. Methods: A systematic search was performed using Medline and Scopus databases. A synthesis of the findings with a critical appraisal was subsequently carried out. The risk of bias was assessed with the Anatomical Quality Assurance Tool. Results: A total of 39 articles, involving 1192 women, were included in the review. Although the perineal membrane, tendinous arch of pelvic fascia, pubourethral ligaments, rectovaginal fascia, and perineal body were the most frequently described structures, uncertainties were Citation: Roch, M.; Gaudreault, N.; identified in micro- and macro-anatomy.
