The management of patients with CBD stone and gallstone
D. Chung
Introduction CBD stone present in 4-10% of those presenting w
ith indication for lap cholecystectomy In era of open cholecystectomy, there was routine
use of IOC +/- exploration (1 stage) With introduction of lap chole, there was move aw
ay from IOC and surgical management of CBD to 2 stage procedure with preop or postop ERCP
Introduction Reason: Lack of expertise for LECBD and
reluctance to convert to open But, pre-op ERCP carries a significant false-
positive rate Today, the advance of lap ECBD is increasingly
reported to return the management of CBD stones to a one stage surgical procedure
Introduction Patient presented with CBD stone and gallstone
Pre op ERCP + LC (2 stage approach) LC + IOC +/- LECBD (1 stage approach)
Introduction
Two-staged approach ERCP & Laparoscopic cholecystectomy
Heinennan PM et al, Ann Surg 1989 Wilson P et al, Lancet 1991 Surick B et al, Surg Endosc 1993 Mayer C et al, J Hepato Pancreat Surg 2002 Chan CM et al, ANZ J Surg 2005
Introduction
One-staged approach Laparoscopic cholecystectomy + laparoscopic e
xploration of common bile duct
Rhodes M et al, Lancet 1998
Cuschieri A et al, Semin Laparosc Surg 2000
Lezoche E et al, Semin Laparosc Surg 2000
Nathanson LK et al, Ann Surg 2005
Paganini AM et al, Surg Endosc 2007
2 stage procedure (ERCP + lap cholecystectomy)
2 stage procedure
Methods Pre-op ERCP + lap chole Lap chole + post op ERCP
2 stage procedure
Advantage Avoid the need of T-tube Avoid the need of choledochotomy Avoid the complications of ECBD Need not to have expertise/operation set-up on
LECBD
1 stage procedure (Lap cholecystectomy + IOC +/- LECBD)
1 stage procedure
Two methods for LECBD 1) Transcystic duct exploration
Preferred method for small CBD stones and small calibre CBD
2) Choledochotomy Multiple (>3), Large CBD stone (>1 cm ) Failed transcystic duct treatment CBD > or = 9 mm on cholangiogram
1 stage procedure
Methods for closure of choledochotomy T-T closure Primary closure with stent Primary closure without stent
1 stage procedure
Factors affecting the result of LECBD Approach to LECBD (Trans-cystic vs choledoc
hotomy) Method for closure of choledochotomy Morbidity
Bile leakage
1 stage procedure Advantage
1 stage procedure/1 admission Less costly Shorter hospital stay (with transcystic duct exploration) Avoid complications of ERCP Fail ERCP Preserve biliary sphincter Avoidance of risk of further stone migration from gallb
ladder to CBD while awaiting for lap chole
Evidence?
Evidence (Case series) Case series for LECBD (Most are transcystic duct explo
ration) 300 patients, 90% ductal clearance
Martin IJ et al, Ann Surg 1998 129 consecutive patients, 92% ductal clearance
Rhodes M et al, Br J Surg 1995 268 consecutive patients, 94.3% ductal clearance
Pahanini AM et al, Ann Ital Chir 2000
Evidence (Randomised trial) Two stage approach VS LECBD (transcysti
c exploration or choledochotomy)1) Rhodes M et al, Lancet 1998 (40 cases/arm)(LC + post op ERCP VS LECBD )2) Cuschieri A et al, Surg Endos 1999 (150 cases/arm)(Pre op ERCP + LC VS LECBD, multicenter trial )
Conclusion: Same ductal clearance rate, shorter hospital stay in LECBD group
Evidence (Randomised trial) Post op ERCP VS LECBD (Choledochotom
y) Nathanson LK et al, Ann Surg 2005
372 cases of CBD stones, with 86 cases (23%) of failed transcystic duct exploration recruited to trial
Choledochotomy 41 VS ERCP clearance 45 No difference in operative time, retained stone r
ate, overall morbidity and mortality
Evidence (Randomised trial) Management of CBD stones, laparoscopic v
ersus endoscopic approach, a comparative study (pre-op ERCP + LC Vs LC + IOC +/- LECBD)
Elbatanouny, A, Zeineldin, A British Journal of Surgery, Volume 93, September 2006
No significant difference in the clearance rate between 2 management options
High rate of unnecessary ERCP in pre-op ERCP group (51.5%)
Evidence (meta-analysis)
Meta-analysis of endoscopy and surgery versus surgery alone for CBD stone with the gallbladder in situ
Clayton, E. S., Connor, S British Journal of Surgery Volume 93(10), October 2006
Evidence (meta-analysis) They identified 12 studies on Medline and ISI
databases that met the inclusion criteria for data extraction (using keywords)
Inclusion and exclusion criteria RCT in English language up to the end of March 2006 Review articles, retrospective analysis and abstracts
were not included
Table 1
Evidence (results)
Outcomes of 1357 patients were studied Successful duct clearance
77.6% in endoscopy + surgery group 79.8% lap CBD surgery group p=0.870 (n.s)
Mortality 0.9% endoscopy + surgery group 0.5% lap CBD surgery group p=0.720 (n.s)
Evidence (results) Total morbidity rate
13.6% in endoscopy + surgery group 17.1% in lap CBD surgery group p=0.710 (n.s)
Need of additional procedures after initial intervention
10.2% in endoscopy + surgery group 9.5% in lap CBD surgery group p=0.90 (n.s)
Evidence (results) No significant difference of successful duct cleara
nce, mortality, total morbidity, major morbidity, need for additional procedures between the endoscopic and surgical groups
Primary closure Vs T-tube RCT on Primary Closure vs T-Tube Closure
after choledochotomy Ha & Li et al, IHBPA 2004
Evidence (Primary closure Vs T-tube)
Primary closure of the CBD is feasible and as safe as T tube insertion after laparoscopic choledochotomy for stone disease Similar morbidity, no mortality 1 bile leak(6.6%) in primary closure group and no bile l
eak in t-tube group Similar operative time ( 108.4 Vs 116.8 minutes, p=0.5
2) Shorter postoperative hospital stay (4 Vs 8 days, p<0.0
01)
Evidence
No consensus to whether which approach is better Similar ductal clearance rate Similar morbidity and mortality

otomy and ERCP 1/25 (4%) Mortality
0%
UCH experience 2005-2006 Follow-up period

Conclusion
Both 1 stage or 2 stage approaches have similar outcomes, and treatment should be determined by local resources and expertise
Our practice for LECBD
LC + LECBD (1 stage approach) Good surgical risk CBD > 1cm 1 or more stones
Especially case with large and multiple stones Fail ERCP
