Severe complications from gallbladder removal are rare. The digestive system may be disrupted for a period of time, but this is expected. In rare cases, more serious complications can develop, including bile leaking into the abdominal cavity, injury to a bile duct, and attacks of pain in the area. Infection, blood clots, and scarring can also occur. Even without a gallbladder, some people still make stones, which can lodge in and obstruct the bile ducts.
