The document discusses several classifications for bile duct injuries following cholecystectomy. The Bismuth classification from 1982 categorizes injuries based on location in the biliary tract into 5 types. The Strasberg classification from 1995 modifies Bismuth and allows differentiation between small and serious injuries from laparoscopic cholecystectomy as Types A-D, with Type E corresponding to Bismuth. The Stewart-Way classification from 2007 is based on injury mechanism and anatomy, categorizing injuries into 4 classes depending on whether the common bile duct was mistaken for the cystic duct and whether it was divided or the extent of injury. Associated vascular injuries also vary depending on the injury class.
This is very important topic for Laparoscopic surgeons,as bile injury is not uncommon,how to approach such biliary injuries is prime to know for evolving surgeons.This slide would also helpful for surgery residents.

Bile duct injury is an unavoidable complication following any laparoscopic or open cholecystectomy. Almost everyone goes through it. One must take care to avoid the BDI, and one must know what to do when it happens.
Carotid blowout syndrome (CBS) is an uncommon but dreaded complication that occurs in patients treated for head and neck cancer. CBS is the result of necrosis of the arterial wall, which can occur following resection, after reirradiation for a recurrent or second primary tumor, by direct tumor invasion of the carotid artery wall or by a combination of these factors.
The incidence of biliary injury after laparoscopic cholecystectomy (LC) has shown a declining trend though it may still be twice that as with open cholecystectomy. Major biliary or vasculobiliary injury is associated with significant morbidity. As prevention is the best strategy, the concept of a culture of safe cholecystectomy has been recently introduced to educate surgeons and apprise them of basic tenets of safe performance of LC. Various aspects of safe cholecystectomy include: (1) thorough knowledge of relevant anatomy, various anatomical landmarks, and anatomical variations; (2) an understanding of the mechanisms involved in biliary/vascular injury, the most important being the misidentification injury; (3) identification of various preoperative and intraoperative predictors of difficult cholecystectomy; (4) proper gallbladder retraction; (5) safe use of various energy devices; (6) understanding the critical view of safety, including its doublet view and documentation; (7) awareness of various error traps (e.g., fundus first technique); (8) use of various bailout strategies (e.g., subtotal cholecystectomy) in difficult gallbladder cases; (9) use of intraoperative imaging techniques (e.g., intraoperative cholangiogram) to ascertain correct anatomy; and (10) understanding the concept of time-out. Surgeons should be facile with these aspects of this culture of safety in cholecystectomy in an attempt to reduce the incidence of biliary/vascular injury during LC.

Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!

2. Introduction :
Laparoscopic cholecystectomy is now the gold
standard for symptomatic cholelithiasis, but it is
associated with a higher incidence of bile duct
injury than open cholecystectomy.
Numerous reports have demonstrated that the
incidence of bile duct injuries has risen from
0.1%-0.2% to 0.4%-0.7% from the era of open
cholecystectomy to the era of laparoscopic
cholecystectomy.
3. Bile duct injury following cholecystectomy is an
iatrogenic catastrophe associated with significant
perioperative morbidity and mortality, reduced long-
term survival and quality of life.
The ease of management, operative risk, and
outcome of bile duct injuries vary considerably, and
are highly dependent on the type of injury and its
location.
Over the years, many classifications of IBDIs have
been occurred before and after the laparoscopic era
to ensure adequate treatment planning.
4. Bismuth classification :
Is the first classification of bile duct injury, authored by H.
Bismuth in 1982.
is a simple classification based on the location of the injury in
the biliary tract and is very helpful in prognosis after repair.
was introduced before laparoscopy. It is difficult to apply in
laparoscopic cholecystectomy as most of the technical
factors and lesion mechanisms are completely different to
open surgery.
This classification included five types of bile duct injuries
according to the distance from the hilar structure especially
bile duct bifurcation, the level of injury, the involvement of bile
duct bifurcation, and individual right sectoral duct.
5. • Bismuth type I : involves the common bile duct and low
common hepatic duct (CHD) >2 cm from the hepatic duct
confluence.
• Bismuth Type II : involves the proximal CHD <2 cm from
the confluence.
• Bismuth Type III : is hilar injury located at the confluence
with the ceiling of it still being intact.
• Bismuth Type IV : is destruction of the confluence when
the right and left hepatic ducts become separated.
• Bismuth Type V : involves the aberrant right sectorial
hepatic duct alone or with concomitant injury of CHD.
6.
7. Strasberg classification 1995 :
The Strasberg classification is a modification of
the Bismuth classification, is very simple which
can be easily applied to bile duct injuries.
Allows differentiation between small (bile leakage
from the cystic duct or aberrant right sectoral
branch) and serious injuries performed during
laparoscopic cholecystectomy as type A to D.
Type E of the Strasberg classification is an
analogue of the Bismuth classification.
8. • Class A : Bile leak from cystic duct stump or minor ducts in
gallbladder fossa.
• Class B : Occluded right posterior sectoral duct.
• Class C : Transection without ligation of the right posterior sectoral
duct.
• Class D : Lateral injuries to major bile ducts.
• Class E : Subdivided as per Bismuth's classification into E1 to E5 :
E1- Stricture/injury at more than 2 cm distal to bifurcation.
E2 - Stricture/injury less than 2 cm distal to bifurcation.
E3- Stricture/injury at bifurcation.
E4 - Stricture/injury involving right and left hepatic ducts.
E5 - Complete obstruction of entire bile duct.
9.
10. Stewart-Way classification :
Published in 2007.
This classification system is based on the
mechanism and anatomy of bile duct injuries
and also includes concomitant vascular
injuries.
Bile duct injuries fall into four classes
according to this classification :
11. Class I injury :
Occurs when CBD is mistaken for
the cystic duct, but the error is
recognized before CBD is divided.
Associated RHA injury (5%).
12. Class II injury :
involve damage to CHD from clips or
cautery used too close to the duct.
This often occurs in cases where visibility
is limited due to inflammation or bleeding.
Associated RHA injury (20%)
13. Class III injury :
the most common type.
occurs when CBD is mistaken for the cystic
duct. The common duct is transected and a
variable portion including the junction of
the cystic and common duct is excised or
removed.
Associated RHA injury (35%)
14. Class IV injury :
involve damage to the right
hepatic duct (RHD), either
because this structure is
mistaken for the cystic duct, or
because it is injured during
dissection.
Damage to Right hepatic artery
(60%) which is mistaken for
cystic artery.
