Cholecystitis SURGICAL MANAGEMENT
Acute Cholecystitis • Acute CalculousCholecystitis • Infectious mechanism from stone impaction in cystic duct • Empiric antibiotics • Laparoscopic vs. Open cholecystectomy • Acute AcalculousCholecystitis • In critically ill patients • High risk for perforation • Percutanouscholecytostomy
Acute Cholangitis • Bactibilia + Biliary obstruction • IV antibiotics • Fluid resuscitation • Biliary drainage • Acute SuppurativeCholangitis • Delineation of proximal bile anatomy • Percutaneoustranshepaticcholangiography and Biliary stent placement
ERCP • Endoscopic Retrograde Cholangiopancreatography • For the diagnosis and treatment of benign and malignant pancreaticobiliary diseases
ERCP • Duodenoscope • Fiber-optic duodenoscope • Videoscope • Catheter • 6 or 7 Fr Teflon tapering to a 3-5 Fr tip
ERCP • Prognosis • Success rate 70%-95% • Complications • Pancreatitis (7.2%) • Hemorrhage (0.8%) • Cholangitis 2° incomplete drainage (0.8%) • Perforation (0.08%) • Others (1.5%) • e.g. Bile peritonitis or bilomas
Post-ERCP Pancreatitis • Patient-related characteristics • sphincter of Oddi dysfunction (21.7%) • previous ERCP-related pancreatitis (19%), and • recurrent pancreatitis (16.2%) • PAIN DURING PROCEDURE (27%) • Technique-related characteristics • precut access papillotomy(20%), • multiple cannulation attempts (14.9%), • sphincterotomeuse (13.1%), • pancreatic duct manipulation (13%), • multiple pancreatic injections (12.3%), • guidewireuse (10.2%), and • extent of pancreatic duct opacification (10%)
Post-ERCP Pancreatitis • Risk Factors • Multiple cannulation attempts >1 (P = 0.0001, OR 3.14, 95 % CI 1.74 - 5.67) • Female sex (P < 0.001, OR 2.22, 95 % CI 1.43 - 3.45) • Age (P < 0.002, OR 1.09 per 5 year decrease, 95 % CI 1.03 - 1.15) • Performance in a district hospital vs. university hospital (P = 0.034, OR 2.41, 95 % CI 1.08 - 5.41) • Pain during procedure • History of recurrent pancreatitis • Precious ERCP-related pancreatitis • Pancreatic brush cytology
Drainage devices • Stents • Plastic stents • 3-11.5 Fr, Polyethylene and Teflon materials • Rapid palliation of obstruction • Shorter hospital stay • Less expensive than metal stents ($100) • Indications • Malignant biliary obstruction • Relieve obstruction of previous metal stents • Benign strictures • Biliary leaks and fistulae • Indwelling stents tmax = 4-6 weeks
Drainage devices • Stents • Self-expandable metal stents (SEMS) • Expansion of 8-10mm • Prolonged patency over plastic stents • Do not occlude from bacterial biofilm • Costly (>$1800)
Drainage devices • Stents • Nasobiliary drainage catheters • 5-7 Fr, 250cm long, 5-9 sideports • For temporary drainage of the biliary tree • Nasal transport tube (reroute tube from mouth to nose) + Connecting tube (for irrigation and drainage)
Drainage devices • Stents • Bioabsorbable stents • Improved patency • Large diameter • Lower biofilm accumulation • Reduced incidence of bile duct proliferative changes • Lesser procedures • Drug elution and control • Antimicrobial or antineoplastic agents impregnated on cover • Bioengineered tissue culture
Drainage devices • Pros • Palliative bypass without invasive surgery • Cons • Device failure • Deployment failure • Malpositioning of stent • Stent occlusion • Complications • Deposition of bacterial biofilm and/or plant material (30%) • Cholecystitis (2.9%-12%) • Stent migration (5%) • Cholangitis • Hemorrhage • Perforation • Pancreatitis • Perforation
