A laparoscopic cholecystoenterostomy, also known as a laparoscopic biliary bypass procedure, is a minimally invasive surgical technique used to create a connection between the gallbladder and the small intestine. This procedure is typically indicated for patients who have conditions that obstruct the normal flow of bile, such as gallstones or tumors. The surgery is performed through small incisions in the abdomen, which reduces recovery time and minimizes postoperative pain compared to traditional open surgery. During the procedure, a trocar is inserted through a small incision at the navel, allowing for the introduction of a laparoscope—a thin tube equipped with a camera that provides visualization of the internal organs. The abdomen is inflated with carbon dioxide to create a working space for the surgeon. Additional incisions are made to insert surgical instruments necessary for the operation. The gallbladder is carefully visualized, and a loop of small bowel, typically from the jejunum, is brought into proximity with the gallbladder. Using a laparoscopic intracorporeal linear stapling device, the gallbladder and small bowel are anastomosed, or surgically connected, to facilitate the passage of bile directly into the intestine. After the anastomosis is completed, the stapler insertion sites are sutured closed, and the surgical instruments are removed before closing the portal incisions. This procedure is designed to restore bile flow and alleviate symptoms associated with biliary obstruction.
