Diagnosis/Preparation
Diagnostically, gallstone disease, which can lead to gallbladder removal, is divided into four diseases: biliary colic, acute cholecystitis, choledocholithiasis, and cholangitis. Biliary colic is usually caused by intermittent cystic duct obstruction by a stone (without any inflammation), causing a severe, poorly localized, and intensifying pain on the upper right side of the abdomen.
These painful attacks can persist from days to months in patients with biliary colic. persons affected with acute cholecystitis caused by an impacted stone in the cystic duct also suffer from gallbladder infection in approximately 50% of cases. These people have moderately severe pain in the upper right portion of the abdomen that lasts longer than six hours. Pain with acute cholecystitis can also extend to the shoulder or back. Since there may be infection inside the gallbladder, the patient may also have fever. On the right side of the abdomen below the last rib, there is usually tenderness with inspiratory (breathing in) arrest (Murphy’s sign). In about 33% of cases of acute cholecystitis, the gallbladder may be felt with palpation (clinician feeling abdomen for tenderness). Mild jaundice can be present in about 20% of cases. Persons with choledocholithiasis, or intermittent obstruction of the common bile duct, often do not have symptoms; but if present, they are indistinguishable from the symptoms of biliary colic.
A more severe form of gallstone disease is cholangitis, which causes stone impaction in the common bile duct. In about 70% of cases, these patients present with Charcot’s triad (pain, jaundice, and fever). Patients with cholangitis may have chills, mild pain, lethargy, and delirium, which indicate that infection has spread to the bloodstream (bacteremia). The majority of patients with cholangitis will have fever (95%), tenderness in the upper right side of the abdomen, and jaundice (80%). In addition to a physical examination, preparation for laboratory (blood) and special tests is essential to gallstone diagnosis. Patients with biliary colic may have elevated bilirubin and should have an ultrasound study to visualize the gallbladder and associated structures. An increase in the white blood cell count (leukocytosis) can be expected for both acute cholecystitis and cholangitis (seen in 80% of cases). Ultrasound testing is recommended for acute cholecystitis patients, whereas ERCP is the test usually indicated to assist in a definitive diagnosis for both choledocholithiasis and cholangitis. Patients with either biliary colic or choledocholithiasis are treated with elective laparoscopic cholecystectomy. Open cholecystectomy is recommended for acute cholecystitis. For cholangitis, emergency ERCP is indicated for stone removal. ERCP therapy can remove stones produced by gallbladder disease.
Aftercare
Without a gallbladder, stones rarely recur. Patients who have continued symptoms after their gallbladder is removed may need an ERCP to detect residual stones or damage to the bile ducts caused by the original stones. Occasionally, the ampulla of Vater is too tight for bile to flow through and causes symptoms until it is opened up.
Risks
The most common medical treatment for gallstones is the surgical removal of the gallbladder (cholecsytectomy). Risks associated with gallbladder removal are low, but include damage to the bile ducts, residual gallstones in the bile ducts, or injury to the surrounding organs. With laparoscopic cholecystectomy, the bile duct damage rate is approximately 0.5%.
Normal results
Most patients undergoing laparoscopic cholecystectomy may go home the same day of surgery, and may immediately return to normal activities and a normal diet, while most patients who undergo open cholecystectomy must remain in the hospital for five to seven days. After one week, they may resume a normal diet, and in four to six weeks they can expect to return to normal activities.
Morbidity and mortality rates
Cholecystectomy is generally a safe procedure, with an overall mortality rate of 0.1–0.3%. The operative mortality rates for open cholecystectomy in males is 0.11% for males aged 30, and 13.84% for males aged 81–90 years. Women seem to tolerate the procedure better than males since mortality rates in females are approximately half those in men for all age groups. The improved technique of laparoscopic cholecystectomy accounts for 90% of all cholecystectomies performed in the United States; the improved technique reduces time missed away from work, patient hospitalization, and postoperative pain.
Alternatives
There are no other acceptable alternatives for gallstone removal besides surgery, shock wave fragmentation, or chemical dissolution
