Q

Universal Protocol

A

A three system principle to be used whenever an invasive surgical procedure is going to be performed.
These principles are:
1) That a preoperative verification of all required documents, results of lab tests, and diagnostic studies are available before the surgery and that the surgery is consistent with the patients expectation
2) Marking the operative site with indelible ink to mark left and right distinction, multiple structures, and levels of the spine
3) A time out before starting the procedure for final verification of the correct patient, procedure, site and any implants

101
What is the point called where the appendix is found?
McBurney’s point
102
What is the cause of acute cholecystitis? What follows after?
Obstruction of the cystic duct by a stone which creates ischemia of the gallbladder wall & mucosa. Chemical & bacterial inflammation follows. Ischemia can lead to necrosis & perforation of the gallbladder wall.
103
What is the cause of chronic cholecystitis? What can be present in the bile due to cholecystitis?
Repeated cases of acute cholecystitis or by irritation by stones. Bacteria can be present in the bile.
104
Who is most at risk of gallbladder disease?
Greater in women who are overweight and who are multiparous
105
What groups have a higher risk of developing gallstones?
Native Americans have higher incidence of gallstones than Caucasians. Thought due to a genetic predisposition to secrete higher levels of cholesterol in bile. Mexican American men & women of all ages also have elevated rates of gallstones
106
What is a non-surgical procedure that can be done to remove gallstones?
Endoscopic retrograde cholangiopancreatography (ERCP)- Scope passes into gallbladder & crushes stones & left to pass on their own. These patients are more prone to pancreatitis. Need to be alert for signs & symptoms of pancreatitis. Extracorporeal shock wave lithotripsy
107
What are some surgical procedures that can be done to remove gallstones?
1) Laparoscopic cholecystectomy is the treatment of choice- minimally invasive, requires hospitalization of 24 hours or less 2) Laparotomy only if there is a reason not to perform a Lap chole 3) If a stone is lodged in a duct, then a cholecystectomy with common duct exploration may be performed resulting in a possible T-Tube is insertion to maintain patency of the duct. 4) Cholecystotomy- Gallbladder is drained & is performed for those who are a poor surgical candidate. 5) Choledochostomy-Removes stones in the duct with T-Tube placement in common duct until healing takes place. Again, for patients who are not good surgical candidates. 6) Percutaneous cholecystectomy-US guided drainage of GB for surgical high risk patients.
