Transverse Loop Colostomy Closure
Transverse Loop Colostomy Closure samer kareem 7,380 Views • 2 years ago

Care must be taken to prevent stenosis at the anastomotic site. If the diameter of the anastomosis is less than 2 cm, the anastomosis should be taken down and resected. A classic end-to-end anastomosis should be performed to ensure adequate diameter to the intestine. If the posterior wall of the colon has been preserved, care should be taken to close the colostomy prior to opening the peritoneal cavity. This will reduce intraperitoneal contamination from the stoma site. Copious irrigation of the wound should be made prior to primary closure. If gross contamination has occurred, delayed closure of the wound should be considered.

In this video Erin K, a tubal reversal patient, explains the symptoms she experienced while suffering from Post Tubal Ligation Syndrome (PTLS). After having tubal reversal surgery her symptoms were relieved. Although numerous women suffer from adverse symptoms after having a tubal ligation, many physicians do not believe PTLS exists.

http://www.nucleushealth.com/ - This 3D medical animation shows the cause and laparoscopic treatment of a ventral incisional hernia. If you have had abdominal surgery in the past, a ventral incisional hernia may appear at the site of your surgical scar. Your intestine may push through a weakened spot in the tissue between your abdominal muscles creating a bulge beneath your skin. If your hernia is not repaired, complications may occur.

Female Pelvic Floor Part 1
Female Pelvic Floor Part 1 Mohamed 71,433 Views • 2 years ago

The pelvic floor or pelvic diaphragm is composed of muscle fibers of the levator ani, the coccygeus, and associated connective tissue which span the area underneath the pelvis. The pelvic diaphragm is a muscular partition formed by the levatores ani and coccygei, with which may be included the parietal pelvic fascia on their upper and lower aspects. The pelvic floor separates the pelvic cavity above from the perineal region (including perineum) below.

The right and left levator ani lie almost horizontally in the floor of the pelvis, separated by a narrow gap that transmits the urethra, vagina, and anal canal. The levator ani is usually considered in three parts: pubococcygeus, puborectalis, and iliococcygeus. The pubococcygeus, the main part of the levator, runs backward from the body of the pubis toward the coccyx and may be damaged during parturition. Some fibers are inserted into the prostate, urethra, and vagina. The right and left puborectalis unite behind the anorectal junction to form a muscular sling . Some regard them as a part of the sphincter ani externus. The iliococcygeus, the most posterior part of the levator ani, is often poorly developed.

The coccygeus, situated behind the levator ani and frequently tendinous as much as muscular, extends from the ischial spine to the lateral margin of the sacrum and coccyx.

The pelvic cavity of the true pelvis has the pelvic floor as its inferior border (and the pelvic brim as its superior border.) The perineum has the pelvic floor as its superior border.

Some sources do not consider “pelvic floor” and “pelvic diaphragm” to be identical, with the “diaphragm” consisting of only the levator ani and coccygeus, while the “floor” also includes the perineal membrane and deep perineal pouch. However, other sources include the fascia as part of the diaphragm. In practice, the two terms are often used interchangeably.

Inferiorly, the pelvic floor extends into the anal triangle.
