Endoscopic papillotomy with removal of common bile duct stones was successfully performed in 14 patients. In 11 patients stones were found after cholecystectomy. In the remaining 3 patients there was a high operative risk. No serious complications occurred. Consequently the removal of choledocholithiasis by endoscopic papillotomy is an alternative to traditional treatment.
A 78-year-old Japanese man with undifferentiated carcinoma of the common bile duct is presented. Upon gross examination, the common bile duct was found to be obstructed by a nodule measuring 10 x 10 mm. Microscopically, the nodule was ill-defined and composed of atypical spindle-shaped and pleomorphic tumor cells. The spindle-shaped cells proliferated in a whirled or interlacing pattern simulating a sarcoma, and the pleomorphic tumor cells had abundant eosinophilic cytoplasm and bizarre nuclei. Histochemically, a few tumor cells contained mucosubstances stained with the alcian blue (AB) method in their cytoplasm. Immunohistochemically, the tumor cells were diffusely positive for CAM5.2 and AE1/AE3. The histological diagnosis was undifferentiated carcinoma (spindle cell carcinoma) of the common bile duct. Other than our patient, only four other cases of undifferentiated carcinoma in the extrahepatic bile duct have been reported in the literature.

A case of cystic fibrosis complicated by common bile duct stenosis is described. Surgery successfully relieved the obstruction, but was complicated by Candida septicaemia. The previously unreported histological abnormalities of the common bile duct are discussed.
The treatment of choledocholithiasis discovered incidentally during laparoscopic cholecystectomy is not yet standardized. Options include laparoscopic common bile duct exploration (LCBDE), postoperative endoscopic retrograde cholangiopancreatography with endoscopic sphincterotomy (ERCP-ES), and no intervention. We undertook a review of our case series to determine whether LCBDE is obligatory and which LCBDE method is unsuccessful. During the 6-year study period, 91 patients with choledocholithiasis were identified. Fifty-six patients (62%) underwent LCBDE. Thirteen (23%) of these 56 patients subsequently required ERCP. Balloon sweeping of the common bile duct failed in 10 of 21 patients (48% failure) compared to any other combination of techniques with a failure rate of 1/33 (3%; P < 0.001). Two patients did not undergo complete duct exploration because of technical problems. Thirty-five patients (38%) did not undergo LCBDE. Nine of these patients (26%) did not have ERCP-ES. None of the patients who underwent postoperative ERCP-ES required additional procedures or surgery. LCBDE can successfully treat common bile duct stones, with minimal to no morbidity, but is not mandatory for safely treating choledocholithiasis. Additionally, advanced techniques for clearing the common bile duct are more successful. Surgeons should be proficient at performing these techniques.
OBJECTIVE: To explore the feasibility of laparoscopic techniques for the removal of common bile duct (CBD) stones. DESIGN: Retrospective analysis. SETTING: University hospital, Sweden. SUBJECTS: 39 patients who underwent laparoscopic common bile duct exploration, either by a transcystic technique or by choledochotomy, between September 1992 and April 1995. INTERVENTIONS: Cholecystectomy, intraoperative cholangiography, and removal of CBD-stones by a transcystic technique (n=22), laparoscopic choledocholithotomy (n=11), or after conversion to open choledocholithotomy (n=6). MAIN OUTCOME MEASURES: Stone clearance rates, operative time, complications, and postoperative hospital stay. RESULTS: Stone removal was achieved in 32/39 patients (82%) by a laparoscopic approach. Reasons for failure were early in our experience, and the result of technical difficulties or stones that were too large for the transcystic approach, or with impacted stones at choledochotomy. Postoperative morbidity was low (n=4, 10%) with no mortality. CONCLUSIONS: Common bile duct stones can be removed in a large proportion of patients undergoing laparoscopic cholecystectomy, either by a laparoscopic transcystic technique or through a laparoscopic choledochotomy. The laparoscopic techniques need further evaluation, preferably in prospective multicentre trials comparing other treatment strategies including endoscopic sphincterotomy.

Strictures, both benign and malignant, of the distal common bile duct (CBD) are reasonably common, and if stented are usually approached endoscopically via the duodenum, or transhepatically via an intrahepatic and then common hepatic duct. We describe a case of endoscopic stenting of a distal CBD stricture over a wire passed percutaneously through the gallbladder, cystic duct and into the duodenum. To our knowledge, this has not been previously described.
OBJECTIVE: To define the incidence of problematic common bile duct calculi in patients undergoing laparoscopic cholecystectomy. SUMMARY BACKGROUND DATA: In patients selected for laparoscopic cholecystectomy, the true incidence of potentially problematic common bile duct calculi and their natural history has not been determined. We evaluated the incidence and early natural history of common bile duct calculi in all patients undergoing laparoscopic cholecystectomy with intraoperative and delayed postoperative cholangiography. METHODS: Operative cholangiography was attempted in all patients. In those patients in whom a filling defect was noted in the bile duct, the fine bore cholangiogram catheter was left securely clipped in the cystic duct for repeated cholangiography at 48 hours and at approximately 6 weeks postoperatively. RESULTS: Operative cholangiography was attempted in 997 consecutive patients and was accomplished in 962 patients (96%). Forty-six patients (4.6%) had at least one filling defect. Twelve of these had a normal cholangiogram at 48 hours (26% possible false-positive operative cholangiogram) and a further 12 at 6 weeks (26% spontaneous passage of calculi). Spontaneous passage was not determined by either the number or size of calculi or by the diameter of the bile duct. Only 22 patients (2.2% of total population) had persistent common bile duct calculi at 6 weeks after laparoscopic cholecystectomy and retrieved by endoscopic retrograde cholangiopancreatography. CONCLUSIONS: Choledocholithiasis occurs in 3.4% of patients undergoing laparoscopic cholecystectomy but more than one third of these pass the calculi spontaneously within 6 weeks of operation and may be spared endoscopic retrograde cholangiopancreatography. Treatment decisions based on assessment by operative cholangiography alone would result in unnecessary interventions in 50% of patients who had either false positive studies or subsequently passed the calculi. These data support a short-term expectant approach in the management of clinically silent choledocholithiasis in patients selected for LC.
Between January 1989 and June 1990, endoscopic sphincterotomy was performed in 308 consecutive patients with common bile duct stones (mean age: 74 years). Complete clearance of common bile duct was achieved at the first attempt in 65% of cases. This rate was significantly related to the size and the number of biliary stones. The success rate reached 97 percent after repeated endoscopic sessions (127 patients), mechanical lithotripsy (20 patients), extracorporeal or intracorporeal lithotripsy (18 and 11 patients, respectively). During the month following the endoscopic sphincterotomy, 39 patients (13%) developed one or more complications and 11 patients (3.7%) died. The complication rate was related to the time elapsed between biliary opacification and endoscopic sphincterotomy (P = 0.04) and between endoscopic sphincterotomy and total common bile duct clearance (P = 0.0007). No patient younger than 75 years died, but death occurred in 4.5% of the patients older than 75 years. Thirty patients (10%) developed endoscopic sphincterotomy-related complications. Cholangitis and bleeding were the most frequent complications (4 and 2%, respectively). Cholangitis occurred more frequently among the patients older than 75 (P < 0.05) or when transhepatic guided endoscopic sphincterotomy or intracorporeal lithotripsy was used (P < 0.005). Cholangitis led to death in 2 patients, 86 and 87 years old (0.7%). Endoscopic sphincterotomy related complications developed within 48 hours in all but 4 patients (2 patients with pancreatitis and 2 patients with cholecystitis).
We report our second case of fracture of a SMART self-expandable metallic stent (Cordis Endovascular, Warren, NJ) placed to treat biliary obstruction due to an unresectable common bile duct carcinoma. An 82-year-old man presented with jaundice. Computed tomography and ultrasonography on admission demonstrated a mass in the lower common bile duct. The mass was identified as a common bile duct obstruction. A SMART stent was inserted. Ten months after stent insertion, two additional SMART stents were inserted to relieve obstructive jaundice due to occlusion of the first stent. Fourteen months after insertion of the first stent, endoscopic examination revealed stenosis of the duodenum due to invasion of the common bile duct carcinoma, prompting us to perform a gastrojejunostomy 1 month later. Three months after gastrojejunostomy, the patient presented with obstructive jaundice and cholangitis. A fracture of one of the stents was then discovered on plain X-ray films and percutaneous transhepatic cholangiography. Two SMART stents were inserted simultaneously. In conclusion, we report the fracture of a SMART stent placed for common bile duct carcinoma. Fracture should be considered as a possible complication after metallic stent insertion.
We report two cases of common bile duct stone formed around a fish bone which migrated from the intestinal tract, along with their characteristic imaging findings. Two patients who had no history of previous operation were admitted because of cholangitis. Percutaneous transhepatic biliary drainage (PTBD) was performed and the cholangiogram showed filling defects with an unusually elongated shape in the common bile duct. After improvement of the cholangitic symptoms, the stones were removed through the PTBD tract under fluoroscopic guidance. A nidus consisting of a 1.5 cm sized fish bone was found in each stone removed.
Seventeen patients underwent treatment for retained common bile duct stones. In 7 patients the stones were removed via a T-tube tract using steerable catheters while 5 patients underwent ERCP and sphincterotomy and 5 underwent surgical re-exploration. Considering morbidity, mortality, success rate and patients' stay in the hospital, non-operative modalities should be the treatment of choice for retained common bile duct stones.
Occasionally, as abdominal surgeons, we are confronted with common bile duct injury noted during video laparoscopic or open cholecystectomy. Usually this is solved by endoscopic retrograde cholangiopancreatography (ERCP) sphincterotomy and stent, or enteric bypass, suture repair and tube drainage. However, after such procedures, there is a significant number of patients with postoperative stenosis. Another alternative to repair common bile duct injury and correct postoperative stenosis is using the round and falciform ligament as circumferencial patch. Due to their closeness to the common bile duct and their adequate blood supply, they make a perfect autologous biological graft.

Iatrogenic injury to the common bile duct during laparoscopic cholecystectomy has previously necessitated an immediate laparotomy to alleviate bile leakage. In the course of 171 laparoscopic cholecystectomies performed at our hospital, intraoperative common bile duct injuries occurred in 2 patients. Each case was successfully treated using a laparoscopically placed T-tube, thus avoiding the need for a laparotomy. This novel intraoperative procedure successfully treated common bile duct injuries without resulting in postoperative complications.
In a rat model, we attempted to describe the natural healing course of the common bile duct (CBD) after primary microsurgical repair. Fifty-three rats were divided into experimental groups with CBD microsurgical anastomoses and control groups with CBD mobilization and ligation. Examination of three experimental groups at 1 week, 1 month, and 3 months showed evolving inflammation and stricture changes with eventual patent, healed ducts in 92% of animals at the end of 3 months following transection and repair. There were no histologic abnormalities in the livers. There were fibrotic ducts and hepatic stasis and cirrhosis changes in the control group with CBD ligation. This study demonstrates that microsurgical techniques can achieve successful primary biliary repair in the rat.
We report two cases of granular cell tumors involving the common bile duct in patients presenting with obstructive jaundice. Pre-operative endoscopic ultrasonography showed short asymmetric stricture with small well delimited hypoechoic mass in the distal common bile duct wall and proximal dilatation. These tumors were misdiagnosed as a bile duct carcinoma in one case and biliary metastasis of a melanoma in the other. Histological examination of the resected specimen showed granular cell tumors. A review of the previously reported cases shows that preoperative diagnosis is uncommon. It should be considered when endoscopic ultrasonography performed for biliary obstruction in a young woman shows a small and well limited hypoechoic mass.
