In this article, the pathogenesis, clinical presentation, diagnosis, and risk of malignancy of endometrial polyps are described. No matter how they present macroscopically, all endometrial polyps have consistent histological features. Adenomyomatous A variation in the balance between mitotic activity and apoptosis that regulates normal endometrium at various stages of the menstrual cycle and estrogen exposure is implicated in the pathogenesis of endometrial polyps. They are most frequently solitary but may be multiple in number and range in size from microscopic to lesions of many centimeters. What is known is that they originate from the endometrial basalis and consist of glands, stroma, and vessels. This vegetative polyp is attached to the endometrium by a relatively narrow stalk. It is, however, important to differentiate preinvasive from invasive disease, by histopathological examination. While the most important risk factor for the development of endometrial polyps appears to be increasing age, other risk factors include obesity or hypertension as systemic features or other gynecological pathologies, such as coexisting cervical polyps, endometriosis, or uterine leiomyomas. For women in the reproductive years, there is an association between endometrial polyps and infertility, although the causal relationship has not been fully elucidated. The primary outcome was pregnancy and the data demonstrated that women having polypectomy had a significantly higher chance of pregnancy. For premenopausal women, the risk of malignancy is low,69 although it is significantly correlated with increasing age and menopausal status, increasing polyp size >15 mm65,66 and tamoxifen use. An exception is papillary serous carcinoma, which may be associated with early omental involvement. Neither ultrasonography nor hysteroscopic features have proven successful in distinguishing benign from malignant endometrial polyps. The availability of sonography and its low cost and low risk will often mean that this is the modality of first choice for initial assessment of polyps. Color-flow Doppler and power Doppler have been used to assist in the further diagnosis of malignancy in polyps, although studies indicate that the addition of Doppler to grayscale scanning has low specificity for malignancy. These techniques may provide future improvements in the prediction of cellular atypia or malignancy within an endometrial polyp; however, they are considered experimental at this time. In addition, defining the pathological features of malignancy within a polyp is not always clear since some authors will consider a polyp malignant only if the stalk itself and surrounding endometrium are free of malignant tissue. This hyperechoic polyp can be seen to separate the anterior and posterior endometrium. The lesions frequently include sonolucent cystic spaces reflecting fluid produced by the columnar elements of the polyp. These modalities may also aid in the discrimination of other types of pathologies including leiomyomas and, as we have previously discussed, facilitate the detection of hyperplastic and malignant changes.

The small or peripheral airways erectile dysfunction and diabetes order cheapest himcolin and himcolin, generally defined as airways less than 2 mm in diameter impotence tumblr buy himcolin overnight delivery, contribute only approximately 10% to 20% of the total resistance. Hence, these airways are frequently called the "silent zone" because disease in them can affect their size without significantly altering the total airway resistance. Unfortunately, despite a great deal of work by physiologists to develop methods capable of detecting increased resistance in small airways, the usefulness of such tests has not met original expectations. The correlation between these functional studies and histopathologic confirmation of disease in small airways has been inconsistent; consequently, these tests are used infrequently. Maximal Expiratory Effort the next important aspect of the physiology of airflow is the distinction between normal breathing and forced or maximal respiratory efforts. A great deal of information can be obtained by looking at flow during a forced expiration. In this figure, a series of expiratory curves shows the kind of flow rates generated by progressively greater expiratory efforts. Curve A shows expiratory flow with a relatively low effort, whereas curve D shows flow with a maximal expiratory effort. During the first part of this curve, until about 30% of vital capacity has been exhaled, the flow rate is quite dependent on the effort expended-that is, greater expiratory efforts cause a continuing increase of expiratory flow rates, which results from increased pleural pressure and thus an increased driving force for expiratory airflow. This region Because resistance to airflow in the tracheobronchial tree depends on the total cross-sectional area of the airways, large and medium-sized airways provide greater resistance than the more numerous small airways. On the downsloping part of curve, beyond the point at which about 30% of vital capacity has been exhaled, flow is limited by mechanical properties of airways and lungs, not by muscular effort. During most of a forced expiration, flow is limited by critical narrowing of the airway; further effort does not result in augmented flow. Below 70% of vital capacity comes a point at which we can no longer increase the flow rate with increasing effort. Something other than our muscular strength (hence, other than the pleural pressure we can generate) limits flow. When we try harder, all we do is compress the airway further without any increase in the flow rate. This part of the flow-volume curve is frequently termed the effort-independent portion because beyond a certain level of effort, further effort does not result in an augmented flow rate. First, why does critical narrowing of the airways occur such that increasing effort proves fruitless in augmenting flow Answers to these questions, which have been of great interest to pulmonary physiologists, must be distilled from a large amount of theory and research. First and most obvious is the inherent size of the airway, which depends on its level in the tracheobronchial tree and the tone of the airway smooth muscle. In disease, smooth muscle tone may be increased (as in asthma), or secretions in the airway may narrow the lumen (as in asthma or chronic bronchitis). Second is the potential collapsibility of the airway, which is affected by the amount of radial traction exerted by surrounding lung tissue on the airway walls. Airways are not isolated structures but are surrounded by a supporting framework of alveolar walls that are constantly "pulling" or "tethering" the airways open. When lung parenchyma is destroyed, as in emphysema, the airways *This discussion uses a model based on the equal pressure point concept. A different model based on wave speed theory probably provides a more accurate conceptual framework for expiratory flow limitation, but it is far more complicated and beyond the scope of this discussion. Schematic diagram of the equal pressure point concept during a forced (maximal) expiration. Alveolar pressure (Palv) has two contributing components: pleural pressure (Ppl) and elastic recoil pressure of lung (Pel). In this diagram, Ppl = 20 cm H2O and Pel = 10 cm H2O, so Palv, the sum of Ppl and Pel, is 30 cm H2O. Third, and perhaps most difficult to understand, is the combination of pressures acting on the airway from without and within.

An alternative tissue extraction route is via minilaparotomy following extension of either the umbilical or a Critical to laparoscopic extirpative surgery are techniques for removing the tissue from the peritoneal cavity that do not require significant expansion of the incisions cough syrup causes erectile dysfunction order discount himcolin line. When considering these techniques erectile dysfunction doctor el paso buy 30gm himcolin fast delivery, it is important to determine potential sequelae of dissemination of fluid or tissue in the peritoneal cavity, as well as the possibility of "seeding" the incision with malignant or even benign tissue such as endometriosis. Endoscopic bags and containers Whereas removing specimens through the laparoscopic ports may save time, tissue may become dislodged resulting in pieces spilling back into the peritoneal cavity, perhaps limiting complete histopathological analysis of the removed tissue. Described the spectrum of tissue morcellation techniques designed to facilitate removal, typically of the uterus or leiomyomas, after laparoscopic surgery. The process can be performed after placing the specimen in a bag; a self-retaining retractor (Video 4. The specimen may then be morcellated through this incision to facilitate its delivery. Following the removal of the specimen, a careful laparoscopic survey of the abdomen should be performed to ensure there is no evidence of spilled specimen pieces. For these reasons, techniques and devices designed to securely close defects made by larger ports, including both the fascia and adjacent peritoneum, are important in laparoscopic surgery. With either approach, it is essential to ensure that bowel or omentum is not incorporated into the incisions. A number of such fascial closure ligature carriers are available, including the Grice needle (Lemaitre Vascular, Inc. This device comprises a reusable rotating cylindrical blade, either 12 or 15 mm in diameter activated by a controller and a foot pedal. Tissue is grasped after passing a tenaculum or similar instrument through the hollow blade, and then drawn into the channel while activating the motor. It is important to never push the device into the endometrial cavity; instead, it should be held stable while the tissue is withdrawn and cut by the rotating blade. The general approach involves introduction of the loaded ligature carrier lateral to the wound edge into the peritoneal cavity while capturing the ipsilateral peritoneum, all under laparoscopic visualization. The suture is then released from the ligature carrier after which the empty instrument is passed through the fascia and peritoneum on the other side of the wound, whereupon it is used to capture and then externalize the free intraperitoneal end. The sutures are then tied to then close both the fascial defect and the underlying peritoneum. One technique described by Spalding92 involves using two hemostats along with a needle driver with suture and needle, preferably a 5/8 round needle. The first hemostat is placed in the fascial wound such that it can be safely elevated by opening the tips of the device. The second hemostat is then used to retract the underlying subcutaneous tissue, while the surgeon passes the needle and suture through the fascia and peritoneum. Safe positioning may also be confirmed by leaving a 5-mm laparoscope in place through a port that does not require fascial closure. A reusable hook ligature carrier device is also available for fascial closure, developed by Jorge et al. To begin closure, the fascial edge is lifted vertically with a hook retractor, and the suture carrier is inserted through the wound under direct vision to pierce through the peritoneum and fascia. A suture is then threaded into the exposed eye of the carrier and brought beneath the fascia. The same suture is then brought to the opposite edge of the wound using the carrier; pulling the stitch from inside to out, which is then tied. If the primary access technique was minilaparotomy (Hasson), similar closure techniques can be used, or the suture placed to anchor the port can be used for closure at the end of the procedure. Skin closure Skin closure may be performed with either skin glue, absorbable subcuticular suture or adhesive strips. The device resembles an insufflation needle, but the obturator has a notch (a) that becomes exposed by pushing the teal colored button in the proximal end. This is done to load the suture C and D to either pass it into the peritoneal cavity or to capture the suture within the peritoneal cavity and externalize it to allow apposition of the wound with a standard knot.
