½ Case presentations of the spectrum of gallstone disease ï½ Summary History of Gallbladder Surgery Gallbladder Surgery: A Relatively Recent Change ï½ Prior to the late 1800s, doctors treated gallbladder disease with a cholecystostomy, due to the fear that removing the organ woul
d kill patients ï½ Carl Johann August Langenbuch (director of the Lazarus Hospital in Berlin, Germany) practiced on a cadaver to remove the gallbladder, and in 1882, performed a cholecystectomy on a patient. He was discharged after 6 weeks in the hospital ï½ By 1897 over 100
cholecystectomies had been performed https://en.wikipedia.org/wiki/Carl_Langenbuch Gallbladder Surgery: A Relatively Recent Change ï½ In 1985, Erich Mühe removed a patientâs gallbladder laparoscopically in Germany ï½ In 1987, Philippe Mouret (a French gynecologic surgeon)
performed a laparoscopic cholecystectomy ï½ In 1992, the National Institutes of Health (NIH) created guidelines for laparoscopic cholecystectomy in the United States, essentially transforming surgical practice Erich Muhe https:// openi.nlm.ni h.gov/detailedresult. php?img=PMC3

a result of solids settling out of solution ï½ Major organic solutes in bile are bilirubin, bile salts, phospholipids, and cholesterol ï½ Gallstones are classified by their cholesterol content ï½ Cholesterol stones ï½ Western countries: approximately 80% of gallstones ï½
Pigment stones ï½ Black ⢠Western countries: approximately 15 - 20% ï½ Brown ⢠Only a small percentage of stones in Western countries Cholesterol Stones ï½ Pure cholesterol stones are uncommon and account for less than 10 % of all stones ï½ Typically occur as single large s
tones with smooth surfaces ï½ Most other cholesterol stones contain variable amounts of bile pigments and calcium, but are always greater than 70 % cholesterol by weight ï½ Usually multiple stones of varying sizes ï½ May be hard and faceted, or irregular, mulberry - shaped,
and soft ï½ Colors range from whitish yellow and green to black ï½ Less than 10 % of cholesterol stones are radiopaque Source: Gallbladder and the Extrahepatic Biliary System, Schwartz's Principles of Surgery, 10e Citation: Brunicardi F, Andersen DK, Billiar TR, Dunn DL, Hunt

Supersaturation ï½ The common primary event in the formation of cholesterol stones is supersaturation of bile with cholesterol ï½ H igh bile cholesterol levels and cholesterol gallstones are considered as one disease ï½ Cholesterol is highly nonpolar and insoluble in water
and bile ï½ Cholesterol solubility depends on the relative concentration of cholesterol, bile salts, and lecithin (the main phospholipid in bile ) ï½ Supersaturation is caused by cholesterol hypersecretion rather than by a reduced secretion of phospholipid or bile salts Source

tones and brown stones have very little in common aside from cholesterol content and should be considered separate entities https://www.flickr.com/photos/jian - hua_qiao_md/3953725382 Black Pigment Stones ï½ Typically small , brittle, black, and sometimes spiculated ï½ Formed by
supersaturation of calcium bilirubinate , carbonate , and phosphate ï½ Most often secondary to hemolytic disorders such as hereditary spherocytosis and sickle cell disease, and in those with cirrhosis ï½ Almost always form in the gallbladder ï½ In Asian countries such as J
apan, black stones account for a much higher percentage of gallstones than in the Western hemisphere Brown Pigment Stones ï½ Typically less than 1 cm in diameter, brownish - yellow, soft, and often mushy ï½ Can form either in the gallbladder or in the bile ducts ï½ Typically
secondary to bacterial infection caused by bile stasis ï½ Precipitated calcium bilirubinate and bacterial cell bodies compose the major part of the stone ï½ Typically found in the biliary tree of Asian populations and are associated with stasis secondary to parasite infectio
