S

Sclerotherapy

For hemorrhoid treatment, a chemical solution is injected around the blood vessel to shrink the hemorrhoid.

For treating portal hypertension, when banding cannot be performed, physicians inject a liquid into the portal artery, which creates scar tissue. This doesn't reduce pressure in the portal vein, but creates a stronger "covering" to contain blood and fluid.

Sigmoidoscopy

Sigmoidoscopy is a diagnosic procedure that allows the physician to examine the lower part of the large intestine - the rectum and bottom two feet of the colon. It is helpful in identifying the causes of diarrhea, abdominal pain, constipation, abnormal growths and bleeding. a thin, flexible tube is inserted into the large intestine through the rectum. The tube has a tiny light and camera at its end that is connected to a TV monitor, allowing the doctor a good view of this part of the large intestine. If necessary, the doctor may take a small tissue sample (biopsy) from the lining of the intestine to look at later under a microscope.

a sigmoidoscopy typically takes 5-10 minutes, requires only an enema for preparation, and can be done without sedation. Patients may experience some cramping and discomfort during this procedure.

Physicians may also couple a sigmoidoscopy with another procedure known as a double-contrast barium enema. With this, barium is infused into the rectum via an enema tube and an x-ray is taken of the area. The barium helps produce a clearer, more detailed x-ray of the area.

Sleeve Gastrectomy

Sleeve Gastrectomy is a new, minimally invasive weight-loss procedure performed in under an hour and carries with it a reduced chance of leakage, infection, and bleeding compared to other weight-loss surgeries. It restricts food intake by the removal of about 60% of the stomach, so that the stomach is reduced to the shape of a tube, or "sleeve."

Surgeons usually perform this procedure on patients who are either extremely obese or who are high-risk, with the intention of performing a second surgery at a subsequent time. The second procedure is usually either a gastric bypass or duodenal switch. This procedure, when part of a combination approach, greatly reduces the risks of bariatric surgery for certain patients, even though it entails two surgeries.

Patients undergoing this procedure usually lose 30-50% of their excess body weight over a 6-12 month period. The timing of the second procedure will depend on the amount of weight lost, and usually take place 6-18 months after the first surgery.

SpyGlass Direct Visualization System for Single-Operator Duodenoscopic-Assisted Cholangiopancreatoscopy (SODAC)

This diagnostic device is similar to ERCP but with better mobility and image clarity. It enables physicians to view hard-to-access ducts in patients with biliary strictures, or narrowing, as well as patients with pre-malignant lesions, and difficult-to-manage stones. The SpyGlass System enables physicians to see the gastrointestinal tract in color and in real time.

Stool Culture

a stool culture checks for the presence of abnormal bacteria in the digestive tract that may cause diarrhea and other problems. a small sample of stool is collected and sent to a laboratory for examination. In two or three days, the test will show whether abnormal bacteria are present.

Strictureplasty

Strictureplasty is a surgical procedure performed in response to scar tissue that has built up in the intestinal wall from inflammatory bowel conditions such as Crohn's disease. As scar tissue builds up, a "stricture", or a narrowing of the bowel, may occur. Also called a side-to-side isoperistaltic strictureplasty (SSIS), strictureplasty is an innovative bowel sparing procedure that has proven highly effective for alleviating symptoms and avoiding major small bowel resections in patients with extensive disease. This procedure provides a larger intestinal channel through which food can transit unimpeded and nutrients can be absorbed. The larger intestinal passageway alleviates symptoms such as cramps, abdominal distension, bloating and vomiting while preserving as much intestine as possible.

Surgical Biopsy

When a needle aspiration biopsy is not conclusive, your doctor may suggest a biopsy in which the tumor and possibly other tissues in the area will be removed by surgery. This procedure is most often done under general anesthesia and often on an outpatient basis. Frequently a biopsy can be performed using laparoscopic techniques (minimally invasive).
