In order to reduce the potential risk of increased surgery due to local tissue edema caused by acute inflammation of the gallbladder and to improve the success rate of minimally invasive surgery, cholecystectomy is usually recommended to be performed some time after the inflammation of the gallbladder has subsided. The surgeon will perform the appropriate preoperative tests before performing the procedure. If it is determined that there is no excessive risk of surgery or anesthesia, the surgeon will usually schedule the surgery as soon as possible. The surgery can be performed in two main ways: one is laparoscopic cholecystectomy, a minimally invasive procedure that is now very widely performed and uses special surgical instruments inserted through multiple small incisions in the abdomen to remove the gallbladder. The other is open cholecystectomy, in which an abdominal incision is made in the upper abdomen next to the midsection, and then the abdominal cavity is accessed to find the gallbladder and remove it completely through a series of measures. There is also a special case where the gallbladder is septic and in poor health, but is in urgent need of treatment. Not being a candidate for gallbladder removal, an alternative procedure called percutaneous cholecystostomy may be performed. This procedure, which is less commonly used today, involves making small incisions at the base of the gallbladder to drain the pus that has accumulated in the gallbladder, then draining the bile outside the body through a drainage tube, and then performing a complete removal of the gallbladder at intervals after the cholecystitis has completely subsided. Although some people who have had their gallbladder removed may experience bloating and diarrhea after eating certain foods, the body can still adapt to living normally without a gallbladder as long as it pays attention to its diet.
