Concentrated bile, cholesterol and calcium can lead to the formation of gallstones in the gallbladder.

The liver produces bile and other digestive enzymes necessary for the breakdown of fats in the diet.
Bile is transported from the liver to the gallbladderthrough a series of biliary ducts – and then to the small intestine.
Any prolonged obstruction that blocks the flowof bile from the liver to the small intestine can result in life-threatening consequences.

From the cystic duct, bile enters the gallbladder where it is concentrated and stored until needed.

When fatty foods are eaten, the gallbladder contracts and sends stored bile back through the cystic duct and common
bile duct into the small intestine.

The First Operation:
Dr. Tauber elects to perform a laparoscopic
cholecystectomy.

![Page 16: Ramos kn 1 july 16.1 09 .key](https://reader038.vdocuments.site/reader038/viewer/2022103115/557e6c1ad8b42a1e178b4f16/html5/thumbnails/16.jpg)
A laparoscopic cholecystectomy
is the surgical removal of the gallbladder through the abdominal wall
with the aid of a laparoscope.

Standard of Care
The correct procedurefor the performance of a
laparoscopic cholecystectomyis as follows:
This is what Dr. Tauber should have done.

![Page 21: Ramos kn 1 july 16.1 09 .key](https://reader038.vdocuments.site/reader038/viewer/2022103115/557e6c1ad8b42a1e178b4f16/html5/thumbnails/21.jpg)
Step 1
Identify, clip and cut the cystic duct.

![Page 22: Ramos kn 1 july 16.1 09 .key](https://reader038.vdocuments.site/reader038/viewer/2022103115/557e6c1ad8b42a1e178b4f16/html5/thumbnails/22.jpg)
Step 2
Identify, clip and cut the cystic artery.

![Page 23: Ramos kn 1 july 16.1 09 .key](https://reader038.vdocuments.site/reader038/viewer/2022103115/557e6c1ad8b42a1e178b4f16/html5/thumbnails/23.jpg)
Step 3
Remove the gallbladder.

![Page 24: Ramos kn 1 july 16.1 09 .key](https://reader038.vdocuments.site/reader038/viewer/2022103115/557e6c1ad8b42a1e178b4f16/html5/thumbnails/24.jpg)
No anatomic structures should be clipped or cut until the surgeon is unequivocally certain
that they have been correctly identified.
The Surgeon’s Cardinal Rule:

Deviation from Standard of Care
These are the 3 major surgical errors committed by Dr. Tauber.
This is what Dr. Tauber did... and what he did not do.

![Page 26: Ramos kn 1 july 16.1 09 .key](https://reader038.vdocuments.site/reader038/viewer/2022103115/557e6c1ad8b42a1e178b4f16/html5/thumbnails/26.jpg)
Surgical Error # 1
Failure to identify the common hepatic duct
26
![Page 27: Ramos kn 1 july 16.1 09 .key](https://reader038.vdocuments.site/reader038/viewer/2022103115/557e6c1ad8b42a1e178b4f16/html5/thumbnails/27.jpg)
Surgical Error # 2
Failure to identify the cystic duct
27
![Page 28: Ramos kn 1 july 16.1 09 .key](https://reader038.vdocuments.site/reader038/viewer/2022103115/557e6c1ad8b42a1e178b4f16/html5/thumbnails/28.jpg)
Surgical Error # 3
Clipping the common hepatic duct
28
![Page 29: Ramos kn 1 july 16.1 09 .key](https://reader038.vdocuments.site/reader038/viewer/2022103115/557e6c1ad8b42a1e178b4f16/html5/thumbnails/29.jpg)
Additional Errors:
Dr. Tauber chose not to use operative cholangiography or ultrasound
which would have helped him to identify critical structures.
29
![Page 30: Ramos kn 1 july 16.1 09 .key](https://reader038.vdocuments.site/reader038/viewer/2022103115/557e6c1ad8b42a1e178b4f16/html5/thumbnails/30.jpg)
Dr. Tauber failed to recognize his surgical errors and therefore failed to diagnose the clipped duct
as the cause of biliary obstruction.
Additional Errors:

![Page 31: Ramos kn 1 july 16.1 09 .key](https://reader038.vdocuments.site/reader038/viewer/2022103115/557e6c1ad8b42a1e178b4f16/html5/thumbnails/31.jpg)
Clipping the common hepatic duct blocks the flow of bile and eventually destroys the duct.

Consequences of Surgical Errors
1. Irreparable damage to the common bile duct.
2. Development of biliary obstruction
3. Multiple invasive diagnostic procedures.
4. Necessity for reconstructive surgery
5. Exposure to additional procedural risks.
6. Permanent scarring and disfigurement.

Any prolonged obstruction that blocks the flow of bile
from the liver to the small intestine can cause serious, life-threatening
consequences.

Soon after laparoscopic cholecystectomy,Maria Santos was discharged from the hospital.
Twenty-one days later she was re-admitted with a diagnosis of acute biliary obstruction.
Continuing Symptoms
Throughout the following weeks, her symptoms grew steadily worse.

Summary
1. During the first gallbladder operation, Dr. Tauber erroneously clipped the common hepatic duct.
2. The clipped duct was the direct cause of biliary obstruction.
3. Worsening symptoms of biliary obstruction necessitated multiple, invasive
diagnostic tests.
54
![Page 55: Ramos kn 1 july 16.1 09 .key](https://reader038.vdocuments.site/reader038/viewer/2022103115/557e6c1ad8b42a1e178b4f16/html5/thumbnails/55.jpg)
Summary4. A second operation was necessary to
reconstruct the damaged bile duct and restore the flow of bile.
5. Further diagnostic tests and therapeutic procedures became necessary to correct the complications of the second operation.
6. Maria Santos is left with unsightly scars, puncture wounds and unremitting pain requiring periodic hospitalizations.
