Transcript

Slide 1-

Gall Stone disease: Etiology, Clinical features, diagnosis, Complications Cholecystectomy: Indications, Procedure, Complications Dr Amit Gupta Associate Professor Dept of Surgery
Slide 2-

What Are Gallstones? Small, pebble-like substances Multiple or solitary May occur anywhere within the biliary tree Have different appearance - depending on their contents
Slide 3-

Pigment Stones Small Friable Irregular Dark Made of bilirubin and calcium salts Less than 20% of cholesterol Risk factors: Haemolysis Liver cirrhosis Biliary tract infections Ileal resection
Slide 4-

Cholesterol Stones Large Often solitary Yellow, white or green Made primarily of cholesterol (>70%) Risk factors: 4 “F” : Female Forty Fertile Fat Fair (5th “F” - more prevalent in Caucasians) Family history (6th “F”)
Slide 5-

Mixed Stones Multiple Faceted Consist of: Calcium salts Pigment Cholesterol (30% - 70%) 80% - associated with chronic cholecystitis
Slide 6-

Gallstone Prevalence 10% of people over 40 yrs. 90% “silent stones” Risk factors for becoming symptomatic: Smoking Parity
Slide 7-

Risk Factors Women Age > 60 years American Indians & Mexican Americans Overweight or obese men and women People who tend to fast or lose weight quickly Family history of gallstones Diabetes Diet high in cholesterol Use of OCPs Pregnancy
Slide 8-

Gallstone Pathogenesis Bile = bile salts, phospholipids, cholesterol Gallstones due to imbalance rendering cholesterol & calcium salts insoluble Pathogenesis involves 3 stages: Cholesterol supersaturation in bile Crystal nucleation Stone growth

Differential Diagnosis Of RUQ Pain Biliary disease Acute cholecystitis, chronic cholecystitis, CBD stone, cholangitis Inflamed or perforated duodenal ulcer Hepatitis Also need to rule out: Appendicitis, renal colic, pneumonia or pleurisy, pancreatitis
Slide 11-

Symptoms Pain in the RUQ Most common and typical symptom May last for a few minutes to several hours Mostly felt after eating a heavy and high-fat meal Pain under right shoulder when lifting up arms Fever, nausea and vomiting Jaundice (obstruction of the bile duct passage) Acute pancreatitis (gallstone enters the duct leading to pancreas and blocks it)
Slide 12-

Murphy’s Sign: Inspiratory arrest with manual pressure below the gallbladder
Slide 13-

Complications Of Gallstones In the GB: Biliary colic Acute and chronic cholecystitis Empyema Mucocoele Carcinoma In the bile ducts: Obstructive jaundice Pancreatitis Cholangitis In the gut: Gallstone ileus
Slide 14-

0.1–0.7% of patients who have gallstones Csendes classification : Type 1: external compression of the common bile duct – 11% Type 2: cholecystobiliary fistula is present involving <1/3 rd the circumference of the bile duct – 41% Type 3: a fistula is present involving upto 2/3 the circumference of the bile duct – 44% Type 4: a fistula is present with complete destruction of the wall of the bile duct – 4% Mirizzi syndrome
Slide 15-

Diagnosis Ultrasound Computerized tomography (CT) scan May show gallstones or complications, such as infection and rupture of GB or bile ducts Cholescintigraphy (HIDA scan) Used to diagnose abnormal contraction of gallbladder or obstruction of bile ducts Endoscopic retrograde cholangiopancreatography (ERCP) Used to locate and remove stones in bile ducts Blood tests Performed to look for signs of infection, obstruction, pancreatitis, or jaundice
Slide 16-

USG CT Scan
Slide 17-

Asymptomatic gallstones do not require operation Whilst awaiting for surgery Low fat diet Dissolution therapy (ursodeoxycholic acid) generally useless Management
Slide 18-

Cholecystostomy Subtotal cholecystectomy Open cholecystectomy Laparoscopic cholecystectomy Surgical options
Slide 19-

Cholecystostomy Patients at high risk related to multisystem organ failure Severe pulmonary, renal, or cardiac disease Recent myocardial infarction Cirrhosis with portal hypertension Acalculus cholecystitis after severe trauma, burns, or surgery Empyema or gangrene of the gallbladder
Slide 20-

Subtotal Cholecystectomy Severe inflammation renders identification of the anatomy impossible, eg. Gangrenous cholecystitis Scarred partially intrahepatic gallbladder Severe cirrhosis and portal hypertension
Slide 21-

Cholecystectomy Laparoscopic Surgery Advantages: Less post-op pain Shorter hospital stay Quicker return to normal activities Disadvantages: Learning curve Inexperience at performing open cholecystectomies

After acute cholecystitis, cholecystectomy traditionally performed after 6 weeks Arguments for 6 weeks later Laparoscopic dissection more difficult when acutely inflammed Surgery not optimal when patient septic/dehydrated Logistical difficulties (theatre space, lack of surgeons) Arguments for same admission Research suggests same admission lap chole as safe as elective chole (conversion to open maybe higher) Waiting increases risk of further attacks/complications which can be life threatening Risk of failure of conservative management and development of dangerous complication such as empyema, gangrene and perforation can be avoided National guidelines state any patient with attack of gallstone pancreatitis should have lap chole within 3 weeks of the attack Cholecystectomy when to perform?
Slide 24-

Complications of Lap Cholecystectomy Trocar/Veress needle injury Hemorrhage Wound infection and/or abscess Ileus Bile leak Gallstone spillage Deep vein thrombosis Retained common bile duct (CBD) stone CBD injury & stricture Pancreatitis Conversion to open procedure
Slide 25-

Nonsurgical treatment: Only in special situations When a patient has a serious medical condition preventing surgery Only for cholesterol stones Oral dissolution therapy Ursodeoxycholic acid - to dissolve cholesterol gallstones Months or years of treatment may be necessary before all stones dissolve Contact dissolution therapy Experimental procedure Involves injecting a drug directly into the gallbladder to dissolve cholesterol stones
Slide 26-

Prevention A sensible diet is the best way to prevent gall stones Avoid crash diet or very low intake of calories Eat good sources of fiber
