Extending from the lateral uter- b ine margin purchase precose with paypal diabetes zentrum mergentheim, the broad ligament connects with the lat- eral pelvic wall buy precose 50mg with mastercard diabetes mellitus signs of hypoglycemia. Thus buy genuine precose diabetes mellitus pathophysiology, the subperitoneal continuity is formed from the pelvic extraperitoneum to the broad ligament to the pelvic organs. The specialized portions of the broad ligament are the mesosalpinx containing the fallopian tubes; the suspensory ligament of the ovary containing the ovarian vessels, lymphatics, and nerves; and the mesometrium containing the uterus. The cardinal ligaments (transverse cervical liga- ments) are the inferior thickened portion of the broad ligament extending from the cervix to the pelvic diaphragm. Direct spread and lymphatic spread from carcinoma uterus to the sacrum and the round ligaments extend of vagina. Tumors of the lower third of the vagina involve inguinal nodes; tumors of the vaginal vault Invasive cervical cancer represents approximately involve the hypogastric and obturator nodes; tumors 15% of gynecologic cancer deaths.

For age- 13 adjusted cancer death rates, there has been a steady spread to the liver and bones is less frequent. Direct extension of cervical cancer occurs after the The uterus is located in the lower pelvis, anterior to the cancer breaks through the basement membrane and rectum and posterior to the urinary bladder. It is penetrates the cervical stroma directly or through vas- divisible by the internal os into two regions, the cervix cular channels.

Patterns of Spread of Gynecologic Disease women, average age 60 years, with increased risk in patients with diabetes mellitus and hypertension. This mass is friable and necrotic causing bleeding, which is the presenting symptom in 90% of patients. The natural history is for the tumor to spread along the endometrial surface and invade the myometrium. The depth of invasion is of significance as the incidence of lymphatic spread increases as the cancer invades the myometrium, 19 especially with greater than 50% involvement. Subperitoneal spread to parametrium from cervical cervix, which is associated with increase in extrauterine cancer. Fixation to the lateral side wall also occurs Breech of the uterine serosa can lead to direct spread with coalescence of pelvic adenopathy and a cervical across fascial planes to adjacent organs including the mass. Direct extension to contiguous organs is uncom- urinary bladder and sigmoid colon. The fundus and superior portion of the Lymphatic spread within the subperitoneal space uterus drain with the ovarian vessels and lymphatics occurs from the cervical lymphatic plexus to the lower to the upper abdominal paraaortic nodes. The middle uterine segment to three groups of draining lympha- and lower regions drain through the broad ligament tics. The upper lymphatics follow the uterine artery, along uterine vessels to the internal iliac nodes. Occa- cross the uterus, and drain to the upper internal iliac sionally, disease spreads to the superficial inguinal (hypogastric) nodes. The lower lymphatics drain to Hematogenous spread is uncommon, especially at the superior and inferior gluteal nodes. Recurrence is most often to the liver, drain cephalad to the common iliac nodes and para- lung, bone, and brain. Supraclavicular node involvement is frequent and represents nodal spread from the para- the peritoneal cavity with resultant intraperitoneal aortic nodes to the cisterna chyli via the thoracic duct spread. Patients with negative nodes have a 90% 5-year survival; those with pelvic nodes have a 50–60% Fallopian Tube 5-year survival; those with paraaortic nodes have a 16,17 20–45% 5-year survival. Fallopian tube carcinoma is the least common site of a Distant recurrence is most frequent to the lung, liver, primary gynecologic malignancy. Lumbar spine involvement is most often by the most common site of origin and mostly present 18 as papillary serous adenocarcinomas.

Radiologic–Anatomic Classification of Intraperitoneal Abscesses Supramesocolic Inframesocolic Right subphrenic Pelvic Anterior Paracolic Posterior Right Right subhepatic Left Anterior Infracolic Posterior Right (Morison’s pouch) Left Left subphrenic Lesser sac Modified with permission from Meyers and Whalen purchase precose without prescription definition of uncontrolled diabetes mellitus. It is important to recognize that only after Mori- son’s pouch is contaminated does the infected material reach the right subphrenic space (Fig. The fluid extends around the inferior edge of the liver or laterally from Morison’s pouch along the inferior reflection of the right coronary ligament and then ascends in the flank to the space above the dome Fig. The triangular-dependent recess of Morison’s pouch is opacified by a small amount of contrast medium. This is bounded posteriorly by the kidney (K), medially by the descending duodenum (D), and inferiorly by the proximal transverse colon (C). The outline particularly of gaseous collections at this site has been referred to as the Doge’s cap sign, since its configuration typically has the shape of a peaked cap reminiscent of ‘‘Il corno,’’ the renaissance headgear worn by the Doge of Venice. Intraperitoneal Spread of Infections and Seeded Metastases passage from the right subphrenic space across the midline to the left subphrenic space is prevented by the falciform ligament. These dynamics of flow explain the incidence and location of intraperitoneal abscesses reported empiri- cally in large clinical series. The frequency of subphre- nic and subhepatic abscesses is two to three times greater on the right than on the left, and the most common site is Morison’s pouch. Abscesses localized solely to the right anterior subhepatic space are rela- tively uncommon. Clinical evi- dence of abscesses limited to the right subphrenic space, however, is not uncommon, but it can be assumed that some contamination of the right posterior subhepatic space had already occurred, perhaps manifested only by some residual inflammatory adhesions. In addition to the ana- tomic pathways and action of gravity, variations in intraperitoneal pressure also determine the distribution of peritoneal fluid. Fluid surmounts the sacral promontory and flank muscles to extend upward, 25 whether the patient is horizontal or erect. The hydrostatic pressure of the contents of the abdominal cavity together with the flexibility of a portion of the abdominal wall determines, for the most part, the pressure within the abdominal cavity. The intraperitoneal pres- sure in the upper abdomen is subatmospheric and decreases further during inspiration. This negative subdiaphragmatic pressure and its relation to breath- ing are maintained in the horizontal or erect position. This is explained by the outward movement of the ribs during inspiration, which enlarges the space in the upper abdomen more than it is decreased by the des- 27 cent of the diaphragm. Salkin subsequently con- firmed these observations in humans, noting in a series of 50 cases that most showed an intraperitoneal pres- Fig. Right subphrenic abscess, following perforation of a sure of from 0 to À30 mm H2O and that pressure is less 28 duodenal ulcer.
