Gallbladder stones are a common and frequent disease in hepatobiliary surgery, mainly cholesterol stones or a mixture of cholesterol-based stones and melanin stones. The causes are very complex, and any factor that affects the ratio of cholesterol to bile acid phospholipid concentration and causes bile stasis may lead to stone formation. Clinical manifestations 1. Some patients with gallbladder stones may be asymptomatic and only found unintentionally during physical examination. 2. Most patients with gallbladder stones may have cholecystitis. Sudden paroxysmal pain in the right upper abdomen or epigastrium after a full meal or eating fatty food may radiate to the right shoulder blade and back, and may even be accompanied by nausea and vomiting. 3.Tiny gallbladder stones may enter the common bile duct through the cystic duct and cause acute cholangitis, obstructive jaundice or biliary pancreatitis. 4, in addition, gallbladder stones and long-term stimulation of inflammation can lead to gallbladder cancer, so do not take it lightly indications for surgical treatment (1) symptomatic gallbladder stones; (2) stones ≥ 2cm in diameter or multiple gallbladder stones; (3) calcification of the gallbladder wall or porcelain gallbladder; (4) gallbladder polyps ≥ 1cm; (5) gradual thickening of the gallbladder wall ≥ 4mm or local thickening or irregularity of the gallbladder wall, suspected of gallbladder cancer patients; (6) patients with gallbladder stones increasing and enlarging year by year or gallbladder neck stones embedded, combined with gallbladder hypofunction or impairment. In addition, it is worth mentioning that according to the latest version of the Expert Consensus on Surgical Treatment of Benign Gallbladder Diseases, gallbladder stones are an indication for surgery regardless of whether they are symptomatic or not. Treatment features of our department At present, our department adopts single-port laparoscopic cholecystectomy technique, which only requires an incision of about 2CM in the umbilicus to complete the operation, and no drainage tube is routinely placed to further ensure the comfort of patients, who can eat and get out of bed within 6 hours after the operation, and can be discharged within 24-48 hours after the operation. This procedure is less traumatic than conventional 3-4 hole laparoscopic surgery and has a faster postoperative recovery, fully embodying minimally invasive, economic, safe, cosmetic and comfortable, which can be said to have five benefits in one stroke.
