1. 300 Laparoscopic Bile Duct Explorations Results and Complications Ahmad Nassar Laparoscopic and Upper GI Service Monklands Hospital Lanarkshire, Scotland Lanarkshire, Scotland

2. Introduction EAES ductal stone study (December 1996) Multi-centre prospective randomized trial Single stage vs. 2 stage CBD clearance – Equal success rates – Shorter hospital stay for single stage – Cost benefits

3. Scottish Survey Questionnaire sent to Scottish surgeons Twice 5 years apart Response: –157 in 1998 (Group A) –77 in 2002 (Group B) Laparoscopic exploration was available to: –14.6% of surgeons Group A (by themselves) –33.8% of surgeons Group B (by themselves)

4. Scottish Survey Although more surgeons capable, less willing to do Laparoscopic exploration was considered the future by 26 surgeons in Group A, but only 18 surgeons in Group B LBDE Group A Group B Non- responder 36 (22.9%) 4 (5.2%) All-comers 2 (1.3%) 0 (0%) Often 3 (1.9%) 3 (3.9%) Occasional 18 (11.5%) 29 (37.6%) Never 98 (62.4%) 41 (53.2%)

5. Patients and Methods Prospective study over 13 years One stage management of all-comers including biliary emergencies Four trocar laparoscopic access Routine intraoperative cholangiogram Transcystic attempts at duct clearance initially Followed by dochotomy ± drainage

6. Patients and Methods 1680 biliary procedures on a referral firm All suspected ductal calculi and most other emergencies 300 bile duct explorations – Transcystic approach 169 patients – Dochotomy 131 patients Glucagon + flushing attempted Glucagon + flushing attempted Followed by trawling with Dormia Followed by trawling with Dormia Prior to choledochoscopic explorations Prior to choledochoscopic explorations

8. Results Intraoperative cholangiogram –ve in 252 patients out of 501 with suspicious CBD stones (50.3%) IOC positive in 92 patients with no CBD stone suspicion n=1170 (7.8%). Presentations Lap.

13. Results - Means

14. Discussion Previous studies have proved cost- effectiveness and decreased hospital stay for laparoscopic biliary exploration Surgeons who overcome learning curve are still reluctant to adopt technique 51.3% of patients who have clinical, ultrasound or biochemical suspicion of duct stones would have unnecessary preoperative investigations

15. Discussion Eight percent silent stones were picked up by routine intraoperative cholangiogram Transcystic ductal exploration: – Clearance achieved with glucagon, flushing and Dormia trawling in 32.2% of patients – Less morbidity – Decreased operative time, shorter hospital stay and shorter presentation-resolution than choledochotomy – Also facilitates simple postoperative biliary drainage

16. Conclusion Laparoscopic single session management of ductal stones is cost-effective with shorter hospital stay than multiple stage management Laparoscopic single session management of ductal stones is cost-effective with shorter hospital stay than multiple stage management Simple transcystic manoeuvres may clear the ducts without formal exploration Simple transcystic manoeuvres may clear the ducts without formal exploration This technique is advocated in preference to endoscopic clearance for surgeons beyond the learning curve This technique is advocated in preference to endoscopic clearance for surgeons beyond the learning curve
