Adjustable Gastric Banding (Lap-Band)

This procedure is less invasive than other gastric procedures because there is no incision made in the stomach or intestine. Instead, surgeons place an adjustable band-like saline tube around the upper part of the stomach to create a small pouch above the band. By adjusting the amount of saline solution in the band after recovery from surgery, the surgeon adjusts the size of the opening between the smaller, upper pouch and the remaining lower portion of the stomach. The tightness of the band opening controls passage of food between the two parts of the stomach, and helps patients feel full after eating.

Losing weight after adjustable gastric band surgery is more gradual than with gastric bypass. Most patients undergoing this procedure lose 40-60% of their excess weight within two years of surgery. The amount of weight lost depends on adapting new eating habits, regular exercise, and follow-up.

Anorectal Manometry

This test helps determine the strength of the muscles in the rectum and anus. These muscles normally tighten to hold in a bowel movement and relax when a bowel movement is passed. Anorectal manometry is helpful in evaluating anorectal malformations and Hirschsprung's disease, among other problems. A small tube is placed into the rectum to measure the pressures exerted by the sphincter muscles that ring the canal.

Antrectomy

This operation removes the lower part of the stomach (antrum), which produces a hormone that stimulates the stomach to secrete digestive juices. Sometimes, a surgeon may also remove an adjacent part of the stomach that secretes pepsin and acid. An antrectomy is usually done in conjunction with a vagotomy, a surgical procedure that involves cutting the vagus nerve in the stomach to reduce acid secretion.
