According to the University of California Medical Center, lap band surgery is generally less risky than more invasive forms of bariatric surgery, including gastric bypass. Complications do occur in some cases, but the band can be removed if complications arise. This procedure involves using a band to create a smaller stomach pouch.
Problems with the Band
The band can slip out of place or erode into the stomach, causing the outermost layer of stomach tissue to break down. If the band slips out of place, it can cause the stomach pouch to enlarge or the stomach outlet to become blocked. Also, a slipped band can cause fluids to leak into the abdominal cavity or an infection can occur where the band is placed.
Digestive Complications
Some patients experience bothersome digestive problems after the placement of the lap band. Reflux and vomiting occur. Other digestive complications include constipation, excessive gas, abdominal bloating, nausea and gastritis.
Surgery Complications
Complications that might arise during the actual surgery include hemorrhaging and injury to nearby organs. The organs that could be injured are the stomach, esophagus and spleen. When surgery complications arise, the physician might need to switch from the usual laroscopic version of the surgery to an open surgical procedure, which poses increased risks.
Other Complications
Other complications that may result after gastric banding include dehydration, difficulty swallowing and failure to produce weight loss.
Serious Complications
Gastric prolapse can occur when the stomach protrudes into the esophagus. Serious complications can also arise as a result of having repeat surgeries to correct complications such as a slipped band. Lap band complications can cause death in 0.5 percent to 1 percent of cases.
