1 Fanelli Laparoscopic Endobiliary Stent
Robert D. Fanelli, MD, FACS Assistant Professor of Surgery University of Massachusetts Medical School Director of Surgical Endoscopy Berkshire Medical Center

2 Laparoscopic Endobiliary Stent Placement
Eliminates need for T-tubes, cystic duct catheters, external drains when Laparoscopic Transcystic Common Bile Duct Exploration (LTCBDE) or Laparoscopic Common Bile Duct Exploration (LCBDE) performed Eliminates need for LTCBDE or LCBDE for Common Bile Duct Stones (CBDS) Protects ductal closures, limits risks of bile leak

3 Laparoscopic Endobiliary Stent Placement
Prevents complications associated with retained CBDS Virtually assures success of postoperative ERCP Necessary equipment inexpensive, readily available Suitable for use in ASCs as well as hospitals

4 Laparoscopic Endobiliary Stent Placement
First described as adjunct to LCBDE, eliminating T-tubes 16 patients ( ) 100% clearance CBDS by LTCBDE and LCBDE No bile leaks, complications 36 to 72 hour LOS Gersin, Fanelli.Surgical Endoscopy, vol.12 (4),April 1998 p. 301.

5 Laparoscopic Endobiliary Stent Placement
Most surgeons rely on postoperative ERCP for CBDS Patients face risks of retained CBDS, pancreatitis, cholangitis, stump leak ERCP results vary based on volume High volume centers, > 95% selective cannulation rate Low volume centers, < 60% selective cannulation rate Average rates of selective cannulation, 80 to 85% 20% patients face reoperation, PTC, or referral for second ERCP for CBDS left at time of LC Conversion, T-tubes, drains deprive patients of low morbidity, quick recovery of LC T-tubes, drains require constant management, delay discharge

6 Laparoscopic Endobiliary Stent Placement
Our current experience (SSAT Scientific Session, May 2000) 372 consecutive LC during 36 months, ending July 1999 Hasson cannula, three 5 mm upper abdominal ports, general anesthesia, CO2 insufflation, routine fluorocholangiography (FC) FC accomplished in all patients CBDS or suspicious FC identified in 48 (12.9%) No attempt made to clear CBDS, all patients treated with stents Stent placement added 9 to 26 minutes to LC operative time Cystic duct balloon dilation necessary in 14 (29.2%) Laparoscopic suturing, advanced skills were not utilized

7 Laparoscopic Endobiliary Stent Placement
Hemorrhage, bile duct injury, duodenal perforation, sub-optimal stent placement, stent migration did not occur Longest f/u 46 months; original series, 80 month f/u 44 (92%) treated as outpatients 4 (8%) admitted overnight with average LOS 30 hours Indications for admission: PONV (2) surgery completed too late for discharge (1) weather too severe for safe discharge (1) Outpatient ERCP with ES 1 to 4 weeks later 100% successful for clearance of CBDS CBDS found in all patients -- no false positive FC No ERCP, stent related complications to date, including pancreatitis

8 Laparoscopic Endobiliary Stent Technique
Routine FC via epigastric port Flexible tip cholangiogram catheter with three-way adapter Three-way adapter permits saline, contrast injection, and placement of wire guide

9 Laparoscopic Endobiliary Stent Technique
150 cm Tracer Hybrid® Wire Guide advanced through cholangiogram catheter Wire guide positioned across ampulla, past CBDS Cholangiogram catheter, removed over wire guide Finger occlusion of epigastric port prevents loss of CO2 Stent introducer port can be used if desired Cystic duct dilated if necessary

10 Laparoscopic Endobiliary Stent Technique
Continuous fluoroscopy Stent assembly advanced over wire guide Position stent across ampulla Radiographic markers assure proper positioning Stent is fixed to delivery mechanism Stent location adjusted as needed prior to deployment Once position perfect, release safety to prepare for deployment

11 Laparoscopic Endobiliary Stent Technique
Radiographic markers Marker 1 - distal tip Marker 2 - distal flange Marker 3 - proximal flange Marker 4 - proximal tip Markers signal deployment Markers 3, 2, and 1 pass through 4 during release After 3, 2, and 1 clear 4, stent is free of delivery system

12 Laparoscopic Endobiliary Stent Technique
Stent successfully deployed Positioned across ampulla Contrast rapidly drains from CBD Cystic duct ligated Cholecystectomy completed Drains are not placed Patient is discharged when alert Placement of stent added 20 minutes to LC operative time

13 Laparoscopic Endobiliary Stent Technique
ERCP 1 to 4 weeks postop Same admission feasible Various ERCP methods Snare removal of stent prior to cannulation, sphincterotomy Wire guide placed via stent prior to retrieval Precut sphincterotomy over stent Cannulate beside stent for sphincterotomy (preferred method)

14 Laparoscopic Endobiliary Stent Kit
Stent and pusher assembly 150 cm Tracer® Hybrid Wire Guide Additional Components Introducer set 12 French cystic duct dilation balloon Cholangiogram catheter with three-way adapter, short wire

15 Conclusions There are numerous methods for treating CBDS during LC
LCBDE is quick and highly successful, but requires refined laparoscopic suturing skills and carries risks of choledochotomy LTCBDE is time consuming, requires expensive equipment and endoscopic, fluoroscopic skills, but avoids choledochotomy Both employ external drains, T-tubes, or cystic duct catheters Laparoscopic stent placement is fast, involves minimal expense, does not require choledochotomy, eliminates external tubes and drains, and virtually assures success of postoperative ERCP
