Anaesthetic
Anaesthetist GA Discuss need for airway protection Use LA When applying for consultant post ask
what access you may have to anaesthetics
![Page 12: Treatment of malignant obstruction Adjunct to surgery Treatment of CBD calculi Treatment of benign strictures Diagnostic? Failed ERCP.](https://reader030.fdocuments.in/reader030/viewer/2022032702/56649cc45503460f9498ddaa/html5/thumbnails/12.jpg)
Antibiotics
At start of procedure Gentamicin 240 mg IV Metronidazole 500 mg IV Discuss with Microbiology
![Page 13: Treatment of malignant obstruction Adjunct to surgery Treatment of CBD calculi Treatment of benign strictures Diagnostic? Failed ERCP.](https://reader030.fdocuments.in/reader030/viewer/2022032702/56649cc45503460f9498ddaa/html5/thumbnails/13.jpg)
Equipment
Use what works best for you Chiba needle 22 gauge Trochar needle 18 gauge NEF set Stiff Terumo wire Amplatz wire Catheters. BMC and straight Self expanding stent Internal/External drains 8.5/10.5F. Discuss
with your surgeon
![Page 14: Treatment of malignant obstruction Adjunct to surgery Treatment of CBD calculi Treatment of benign strictures Diagnostic? Failed ERCP.](https://reader030.fdocuments.in/reader030/viewer/2022032702/56649cc45503460f9498ddaa/html5/thumbnails/14.jpg)
Approach/Technique 1
Ascites present? Drain first Ultrasound? Right lobe. Mid axillary line. Aim for xyphisternum. Left lobe. Locate with U/S and usually aim for
segment III. Very gently inject 1/3 strength contrast (100) as
needle is withdrawn Duct entered when contrast flows away from
needle and persists Duct not entered. Change angle and try not to exit
liver capsule Duct normally anterior to portal vein
![Page 15: Treatment of malignant obstruction Adjunct to surgery Treatment of CBD calculi Treatment of benign strictures Diagnostic? Failed ERCP.](https://reader030.fdocuments.in/reader030/viewer/2022032702/56649cc45503460f9498ddaa/html5/thumbnails/15.jpg)
Approach/Technique 2
Pre-surgery for cholangiocarcinoma. Discuss lobe to drain. Usually the lobe being preserved.
Pre-surgery for pancreatic cancer. Right lobe puncture.
Palliative. Drain right, left or both? 1. Chiba needle to opacify ducts then choose
duct for trochar puncture and wire etc. 2. NEF set. Single puncture then wire, dilator
and access sheath Consider bile for cytology if no diagnosis
![Page 16: Treatment of malignant obstruction Adjunct to surgery Treatment of CBD calculi Treatment of benign strictures Diagnostic? Failed ERCP.](https://reader030.fdocuments.in/reader030/viewer/2022032702/56649cc45503460f9498ddaa/html5/thumbnails/16.jpg)
Approach/Technique 3
Stiff Terumo to cross lesion. Use pin vice for torque
Straight catheter Amplatz wire Dilator Stent/Drain 1 or 2 stage procedure? Temporary drain following stent? Plug track? Coils, gelfoam etc. Technical success >95% (BSIR audit)
![Page 17: Treatment of malignant obstruction Adjunct to surgery Treatment of CBD calculi Treatment of benign strictures Diagnostic? Failed ERCP.](https://reader030.fdocuments.in/reader030/viewer/2022032702/56649cc45503460f9498ddaa/html5/thumbnails/17.jpg)
Approach/Technique 4
Unable to cross stricture, establish external drainage (8.5F internal/external drain). Further attempt after decompression usually successful.
Care with drainage bag essential. Internal external drainage, try not to use
bag and bung catheter.

BSIR Audit. Mortality & Complications (reported)
In hospital mortality 19.8%. Death or major complication 21.2% overall, 18.3%
benign, 21.7% malignant. Major complications in 7.9%, haemorrhage 3.5%,
renal failure 1.8% and sepsis 1.6%. Minor complications in 26.0%, pain 14.3%, sepsis
7.7% and haemorrhage 4.5%. Association with ascites, elevated INR and low
platelets. 1 year survival <20% for malignant disease. Drainage more effective if stents placed across
ampulla
![Page 19: Treatment of malignant obstruction Adjunct to surgery Treatment of CBD calculi Treatment of benign strictures Diagnostic? Failed ERCP.](https://reader030.fdocuments.in/reader030/viewer/2022032702/56649cc45503460f9498ddaa/html5/thumbnails/19.jpg)
BSIR recommendations
1. Further audit of this cohort is required to determine cause of death and to demonstrate whether or not there are significant associated risk factors.
2. Given the high mortality in this group of patients further data collection will be required. Significant improvements in data completeness are required. Data submission remains voluntary, but NHS services should consider how they can make resources available to support data collection for individual operators
