Biliary Injury During Laparoscopic Cholecystectomy
Dr. Lam Tang Yu Department of Surgery, Tuen Mun Hospital Joint Hospital Surgical Grand Round (JHSGR) Ruttonjee Hospital, 24/10/2015
2
Outline Incidence Cases sharing Risks factors
Presentation, classification and management Prevention
3
Incidence of Biliary Injury In Cholecystectomy
Incidence for open, % (1-2) Incidence for laparoscopic cholecystectomy, 0.3 – 0.7% (1-2) SOMIP (11) : elective cholecystectomy - 97.6% laparoscopic approach; 6.3% conversion (115) - 0.6% biliary fistula - 0.1%, 1 case CBD injury (0.2%, 3 cases in 12/13, 11/12)
4
Our center in the past 5 year
Case I: Laparoscopic cholecystectomy for chronic cholecystitis, 2012 - CBD confluence injury - Hepatico-jejunostomy performed 3 months later - recover uneventfully CBD confluence injury in 04/2012 We performed HJ in 08/15 Recovery uneventfuly
5
Our center in the past 5 year
Case II: Symptomatic GS with lap cholecystectomy, 2015 - jaundice on post-op day 2 - CT: dilated biliary tree - percutaneous transheaptic cholangiogram + external drainage - HJ performed three months later
6
Risks factors Main risk factor were thought: inexperience
aberrant anatomy inflammation Review by S M Strasberg (10) in 1995: - initial report: learning curve did related to injuries - later reports: the more experienced the more common for biliary injury
7
Risks factors An analysis (3) in 2003 (252 biliary injury cases)
visual perception illusion in 97% of cases experience NOT related
8
Management of Biliary Injury
depends on time of recognition Intra-operative recognition less than 1/3 patient (4) consult an experience surgeon convert to laparotomy with cholangiogram, define the nature of injury repair accordingly: primary repair / T-tube / HJ higher successful rate, few morbidity/mortality (5)
9
Intra-operative recognition
If expertise not a/v: no attempt should be made; as would cause further biliary / vascular injury external biliary drainage, drain to sub-hepatic space refer to specialized hepatobiliary center Stewart et al. (1995): 1. Repair success rate: 17% (primary surgeon) Vs 94% (tertiary biliary surgeon) 2. Hospital stay: 222 Vs 78 days 3. Morbidity: 58 Vs 4% 4. Mortality: 1.6 Vs 0% Flum et al. (2003): adjusted hazard of death during follow-up was 11% greater if the repairing surgeon was the same as the injuring surgeon Heise et al. (2003): no. of repairs before referral was a significant predictor of poor outcome
10
Post-operative recognition
Presentation: - abdominal pain, fever, bile from drain, bile peritonitis - bilirubin may elevated - secondary biliary cirrhosis - or any deviation from an uneventful postoperative course
11
Principle of management for post-op recognition:
1. Control of sepsis and fluid resuscitation 2. Delineate biliary anatomy / vascular injury USG, MRCP CT PTC for biliary drainage + cholangiogram ERCP +/- stenting for leakage injury 3. Definitive treatment: re-establish biliary enteric continuity
12
A lot of Classification…
13
Classification: Bismuth classification for benign biliary stricture, 1982
In general, the higher the injury / stricture, the more difficult is the repair and the greater the recurrence Bismuth, developed in the era of open surgery, 1982
14
Classification: Strassberg - Bismuth, 1995
Strassberg: including other types of laparoscopic injury
15
Classification: Strassberg-Bismuth, 1995
16
Classification: Stewart-Way, 2003
Class I: injury occurs when CBD mistaken for cystic duct, but the error is recognized before CBD is divided; or make a small cut for cholangiogram Class II: damage to CHD from clips or cautery used too closed to the duct, often occurs in case of visibility is limited due to inflammation / bleeding Class III: CBD mistaken as cystic duct, then transected CHD unknowingly as the gallbladder separated from liver; subdivided into four sub-classes (similar to Strassberg Es) Class IV: damage to right hepatic duct as mistaken as cystic duct, often combination injury to right hepatic artery as mistaken as cystic artery Stewart proposed a classification system based on the mechanism of the injury
17
Definitive treatment (10)
Strassberg Classification Surgical procedure A ERCP + stent +/- sphincterotomy B - Conservative for asymptomatic; - HJ for symptomatic; - Liver resection when biliary-enteric anastomosis not possible C - HJ; - Ligation if HJ not possible D ERCP; T Tube; HJ E HJ
18
Definitive treatment for associated vascular injury
arterial disruption: -bile duct ischemia -higher rate of anastomotic leakage an independent predictor of mortality, with 38% of patient compared to 3% (6) some suggested routine arteriography before repair consider arterial reconstruction during HJ CT showed any liver atrophy / ongoing sepsis => liver resection
19
Timing for re-construction is variable…
S M Strasberg (10) advocated delay repair: greatest inflammation at the initial post-operative period the process of cauterization and devascularization injury may progress over months
20
So how late is delay… Ajay K Sahajpal et al (69 cases) (7):
- advocated immediate repair (0-72 hours) or late repair (>6 week) intermediate repair significant associated with biliary stricture de Reuver et al (151 cases) (8): repair within 6 week significant higher rate of stricture Lygia Stewart and Lawrence et al (307 cases) (9): - success depend on: complete eradication of abdominal infection; pre-op complete cholangiography; repair by experienced biliary surgeon - no correlation between timing of reconstruction minimal peritoneal contamination / sepsis=> early repair wait for sepsis / soiling resolved => delay repair
21
Tips of successful HJ preoperative placement of trans-hepatic tubes
common hepatic duct should be open as proximal as possible use extra-hepatic portion of the left hepatic duct for a wide anastomosis for E4, joining individual hepatic ducts before jejunal anastomosis
22
Most importantly: prevention
indication for cholecystectomy… perform a safe laparoscopic cholecystectomy correct traction identification of supraduodenal CBD before any dissection start dissection start at the junction of the gallbladder and cystic duct avoid thermal injury, use electrocautery sparingly and with short burst
23
CRITICAL VIEW of SAFETY
- the hepatocystic triangle cleared of fat and fibrous tissue - cystic plate exposed (1/3 of gallbladder separated from liver) - TWO and ONLY TWO tubular structures entering the gallbladder use intra-operative cholangiography if any doubt consider conversion / fundus first / subtotal cholecystectomy
24
Bring Home Message Perform safe laparoscopic cholecystectomy
Convert open / consult expertise if any doubt Resuscitation, control sepsis, delineate anatomy and repair by expertise are important factors for successful management of biliary injury
