Multiple sclerosis (MS) involves an immune-mediated process in which an abnormal response of the body’s immune system is directed against the central nervous system (CNS). The CNS is made up of the brain, spinal cord and optic nerves.
As one of the first pediatric centers in the United States to use a new state-of-the-art MRI machine designed especially for kids, Children's Hospital of Michigan continues to deliver world-class, patient-friendly health care. ~ Detroit Medical Center
Following Dr. Eric Skarsgard on his grueling 19-hour day at BC Children's Hospital, we meet several of his patients -- some of who need surgery that day, and some who have chronic conditions and need regular check-ups with him -- and learn how he works with medical students and on research projects as time allows.
An undescended testicle (cryptorchidism) is a testicle that hasn't moved into its proper position in the bag of skin hanging below the penis (scrotum) before birth. Usually just one testicle is affected, but about 10 percent of the time both testicles are undescended. An undescended testicle is uncommon in general, but common among baby boys born prematurely. The vast majority of the time, the undescended testicle moves into the proper position on its own, within the first few months of life. If your son has an undescended testicle that doesn't correct itself, surgery can relocate the testicle into the scrotum.
The 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.

What is Laparoscopic Surgery:
Laparoscopic surgery describes procedures performed using one or multiple small incisions in the abdominal wall in contrast to the larger, normally singular incision of laparotomy. The technique is based around principles of minimally invasive surgery (or minimal access surgery): a large group of modern surgical procedures carried out by entering the body with the smallest possible damage to tissues. In abdominopelvic surgery, minimally invasive surgery is generally treated as synonymous with laparoscopic surgery as are procedures not technically within the peritoneal cavity, such as totally extraperitoneal hernia repair, or extending beyond the abdomen, such as thoraco-laparoscopic esophagectomy. The term laparoscopy is sometimes used interchangeably, although this is often reserved to describe a visual examination of the peritoneal cavity or the purely scopic component of a laparoscopic procedure. The colloquial keyhole surgery is common in non-medical usage.
Surgical Objective of Laparoscopic Surgery:
The objective of a laparoscopic approach is to minimize surgical trauma when operating on abdominal or pelvic structures. When correctly indicated and performed, this can result in smaller scars, reduced postoperative morbidity, shorter inpatient durations, and a faster return to normal activity. For a number of abdominopelvic procedures, a laparoscopic approach is now generally considered to be the gold-standard treatment option.

Developments of Laparoscopic Surgery:
Following a number of smaller-scale applications of minimally invasive techniques to abdominopelvic surgery, laparoscopic surgery became a major part of general surgical practice with the introduction of laparoscopic cholecystectomy in the 1980s and the subsequent pioneering of endoscopic camera technology. This led to the widespread adoption of the technique by the early- to mid-1990s. The portfolio of procedures that can be performed laparoscopically has rapidly expanded with improvements in instruments, imaging, techniques and training — forming a central component of modern surgical practice and cross-specialty curricula [2]. Techniques such as laparoscopically assisted surgery and hand-assisted laparoscopic surgery have allowed the application of laparoscopic techniques to a greater variety of pathology. Single-incision laparoscopic surgery, natural orifice transluminal endoscopic surgery, and minilaparoscopy-assisted natural orifice surgery continue to push forward the applications of minimally invasive abdominopelvic techniques; however, the widespread practice and specific indications for these remain to be fully established. More recently, robotic surgery has been able to build on laparoscopic principles through developments in visualization, ergonomics, and instrumentation.
