Diagnosis and prognosis of AIDS-related cholangitis.

OBJECTIVE: To determine more precisely the clinical and biological characteristics of AIDS-related cholangitis, and to investigate prognostic variables of this disease. DESIGN: Retrospective clinical and prognostic study. SETTING: Biliary unit, Bicêtre Hospital, France. PATIENTS: HIV-positive patients (n = 52) referred to the unit between December 1986 and June 1993 for biliary symptoms leading to the suspicion of AIDS-related cholangitis, (42 men; 10 women; mean age, 37 +/- 8 years). INTERVENTION: Endoscopic retrograde cholangiopancreatography (ERCP) was performed in order to determine the cause of the biliary symptoms. MAIN OUTCOME MEASURE: Clinical features and evolution of the cholangitis. RESULTS: Among the 52 patients, 45 met the ERCP criteria of AIDS-related cholangitis (36 men; nine women). The diagnosis of cholangitis was strongly suggested by abdominal ultrasonography in 47% of the cases. ERCP showed papillary stenosis, diffuse cholangitis, extrahepatic cholangitis alone, and intrahepatic cholangitis alone in 60, 67, 7 and 27%, respectively. Endoscopic sphincterotomy was performed in 28 patients. Pain was relieved by sphincterotomy in nine patients, but the other clinical or biological features were not influenced. One-year and 2-year survival rates were 41 +/- 7% and 8 +/- 4%, respectively. Multidimensional analysis using a Cox model showed that a lymphocyte count > 500 x 10(6)/l was the only independent predictive factor of better survival. CONCLUSION: AIDS-related cholangitis is a disease which leads preferentially to papillary stenosis or diffuse abnormalities of the biliary tract. Prognostic factors depend on the stage of the HIV infection. Another diagnosis of cholestasis was found in approximately 15% of the patients who showed biliary symptoms.

Bile levels of carcino-embryonic antigen in patients with hepatopancreatobiliary disease.

OBJECTIVE: To evaluate the value of biliary carcino-embryonic antigen (CEA) in the differential diagnosis of malignant and benign hepatopancreatobiliary disease. PATIENTS: One hundred patients were prospectively studied. Benign diseases were present in 39% of the patients while 61% had malignant diseases. METHODS: Samples of serum were taken from all patients just before endoscopic retrograde cholangiopancreatography (ERCP) and samples of biliary CEA were obtained during ERCP. RESULTS: The sensitivity of serum CEA and carbohydrate antigen 19-9 (CA 19-9) in detecting malignancy were 50% and 92%, respectively, while the respective specificities were 95% and 72%. The mean biliary CEA level of the benign group was significantly different from that of the malignant group (35.7 +/- 8.7 ng/ml vs 268 +/- 85.5 ng/ml), but there was considerable overlap between the two groups. With a cut-off level of 20 ng/ml, the sensitivity and specificity were 84% and 64% respectively. The mean bilirubinaemia value was significantly higher in malignant disease than in benign disease (57.4 +/- 13.9 mumol/l vs 235 +/- 19.8 mumol/l). Multidimensional analysis indicated that only bilirubinaemia (P < 109-3)) was independently predictive of malignant disease. CONCLUSION: Biliary CEA assessment seems useless in distinguished between benign and malignant causes of cholestasis.

Diagnostic ERCP in the era of laparoscopic surgery.

BACKGROUND/AIMS: The purpose of this paper is to reassess the place and risks of ERCP in a diagnostic view. METHODS: Analysis of 196 non-operative ERCP performed in 196 patients aged 57 +/- 20 yrs. ERCP was performed for: unexplained cholestasis = 98; non tumoral pancreatic diseases = 43; suspected neoplasm of the pancreatic/biliary tract = 13; cholangitis = 12; unexplained abdominal pain = 30. Precut papillotomy was performed in 40 cases (20.4%). 10.7% were cirrhotics; 3.1% were gastrectomized. 164/196 received peri-operative broad-spectrum antibiotics. RESULTS: 108 had normal ERCP (group I); 74 had abnormal ERCP (group II); 12 had undetermined diagnosis after ERCP (group III). Strictly ERCP-induced mortality was nil; 2 patients died a few days after ERCP from: hemorrhage after transhepatic drainage (1); continuing severe cholangitis after failed CBD cannulation (1). Morbidity was: acute pancreatitis = 6 (3%) and fever = 4 (2%). No complication followed precut papillotomy. The 6 pancreatitis recovered within 48 h to 5 days. Fevers alleviated with antibiotics within 12 to 48 h. Pancreatitis occurred in 5/6 after normal ERCP; fevers followed pathologic ERCP in 3/4 (NS). The high rate of precuts in this series did not increase morbidity. CONCLUSION: ERCP-related morbidity was 5.1 % and ERCP accurately diagnosed or unequivocally eliminated biliary-pancreatic disease in 92.9%. These results suggest that ERCP remains a useful and safe diagnostic tool.

[Portal cavernoma compressing the bile duct. Apropos of three cases]. / Cavernome portal comprimant la voie biliaire. Etude de 3 cas.

Three cases of biliary tract compression caused by a cavernous transformation of the portal vein are reported. Revealing symptoms of biliary disease were anicteric and asymptomatic cholestasis in one patient, and cholangitis and obstructive jaundice in one case each. Endoscopic retrograde cholangiograms showed that the compression was located in the common bile duct in two cases and in the main bile duct in one. The responsibility of the portal cavernoma was established by the disappearance of jaundice after splenorenal shunt in one case. Biliary consequences of a portal cavernoma are very uncommon. Compression by the turgescent venous network combined with a sclero-inflammatory reaction of the biliary tract are the most likely causes.

[Lithiasis of the common bile duct in the aged subject treated with endoscopy (227 patients)]. / Lithiase de la voie biliaire principale du sujet âgé traitée par voie endoscopique (277 malades).

One hundred and sixteen patients aged from 65 to 80 years (first group including 39 previously cholecystectomized patients) and 161 patients aged over 80 years (second group, including 31 previously cholecystectomized patients) underwent endoscopic papillotomy for choledocholithiasis. We compared clinical, biochemical and morphological features of choledocolithiasis with early results of endoscopic papillotomy. Clinical symptoms were not different between the old and very old patients, cholecystectomized or not. Charcot's triade was observed in one third of patients. Biochemical data just before endoscopic retrograde cholangiography were not different according to groups: 21 p. 100 of the 277 patients had a biological cholestasis without elevation of bilirubin and 10 p. 100 of the patients had no abnormality of the liver function. Diagnosis of choledocholithiasis was accurately suspected in 90 p. 100 of patients. Complete removal of gallstones after endoscopic papillotomy was obtained in 95 p. 100 of patients in the first group and 93 p. 100 of patients in the second group. Morbidity and mortality rates related to endoscopic papillotomy were not different between the 2 groups (6.9 and 0.8 p. 100 in the first group and 8.7 and 3.1 p. 100 in the second group, the first group and 8.7 and 3.1 p. 100 in the second group, respectively). These results suggest that clinical and biochemical features of choledocholithiasis, and early results of endoscopic treatment do not present any particularities in the elderly.

[Psoas abscess exteriorized in the groin revealed late after acute pancreatitis]. / Abcès du psoas extériorisé au creux inguinal se révélant tardivement après une pancréatite aiguë.

Two cases of psoas abscess complicating acute necrotizing pancreatitis are reported. These cases were particular because the abscesses exteriorized in the groin and symptoms were misleading. The abscesses were detected late, three and five months after the beginning of the pancreatitis respectively. The difficulties in diagnosis and the long delay to diagnosis are emphasized as possible sources of superinfection.

[Late biliary complications after endoscopic sphincterotomy for common bile duct stones in patients older than 65 years of age with gallbladder in situ]. / Complications biliaires à long terme après sphinctérotomie endoscopique pour lithiase de la voie biliaire principale chez les malades de plus de 65 ans avec vésicule biliaire en place.

UNLABELLED: The aim of this retrospective study was to evaluate the nature and the frequency of biliary complications after endoscopic retrograde cholangiography for common bile duct stones in elderly patients with gallbladder in situ. METHODS: Between 1991 and 1993, 169 consecutive patients with gallbladder in situ, older than 65 years (79 +/- 8) had an endoscopic retrograde cholangiography with sphincterotomy for choledocholithiasis. Information on the early (<1 month) and late biliary complications, treatment and mortality were obtained by mail or phone calls from patients and general practitioners. Long-term data were obtained for 139 patients (82%). Mean follow-up was 56.5 months (80 months for patients still alive at the end of the study). RESULTS: Early complications occurred in 13 patients (10.8%). Seven patients had acute cholecystitis, present before the procedure in all cases; all were treated by surgery. Other early complications included cholangitis (n =7), mild acute pancreatitis (n =3), bleeding (n =1), perforation (n =1), biliary colic (n =1), pneumopathy (n =1) and bradycardia (n =1), all treated medically. Forty patients underwent early cholecystectomy, and 5 died during the first month without biliary disease. Late complications were thus assessed in 94 patients and occurred in 13 (14%), i.e around 2% per year. Complications were acute cholangitis (n=4), biliary pain (n =4), cholecystitis (n =2), abdominal pain (n =2) and jaundice due to sphincterotomy stenosis (n =1). Five patients had cholecystectomy, 1 a radiological drainage and 7 were treated medically. No death due to a biliary complication was observed. The presence of gallstones, the absence of gallbladder opacification at cholangiography were not prognostic factors for the recurrence of biliary symptoms. 65 patients (50%) died without biliary disease during the follow-up (actuarial death rate 10.5% per year). CONCLUSION: Late biliary complications after endoscopic retrograde cholangiography for choledocholithiasis in patients with gallbladder in situ are rare (2% per year). Prophylactic cholecystectomy after sphincterotomy does not seem warranted in elderly patients, because of rare recurrent biliary symptoms, low mortality rate, and limited life expectancy.

[Intra-corporeal shockwave lithotripsy in the treatment of complex lithiasis of the bile ducts. Comparison of endoscopic techniques and long-term results]. / Lithotritie intra-corporelle par ondes de choc dans le traitement des lithiases complexes des voies biliaires. Comparaison des techniques endoscopiques et résultat à distance.

OBJECTIVES: About 2% of common bile duct stones and most intra-hepatic stones cannot be removed by conventional endoscopy. Intra-corporeal lithotripsy is an alternative technique for these patients. Contact lithotripsy can be obtained by a pulsed dye laser or by electro-hydraulic shockwaves. We compared and assessed the results of these two methods. METHODS: Thirty-seven patients (79 +/- 9.8 years, 25 women and 12 men) underwent laser lithotripsy (n = 21), electro-hydraulic lithotripsy (n = 9) or both methods consecutively (n = 7) for common bile duct stones (n = 31), intra-hepatic stones (n = 3) or diffuse lithiasis (n = 3). The mean diameter of the largest stone was 23 +/- 12 mm. Lithotripsy was performed by a retrograde approach in 35 cases and a combined, retrograde and transhepatic approach in 2 cases. RESULTS: The mean number of lithotripsy sessions was 1.5 +/- 0.65. The overall success rate (free bile ducts with patent drainage) was 95%. In 2 patients, stones were not fully extracted: one underwent surgery, the other one was treated conservatively with antibiotics. The duration of the hospital stay was 9.3 +/- 4.5 days. Morbidity at 30 days was 27% and only one case of major morbidity (hemorrhage after sphincterotomy, 2.7%) was observed. There were no procedure-related mortality. Electro-hydraulic and laser groups did not differ significantly for success rate, morbidity and time spent at hospital. Follow-up information was obtained in 34 patients (91.8%) a median of 17 months after lithotripsy (range: 4.52 months). Ten patients died of non-biliary diseases. Two patients (5.8%) developed biliary symptoms 24 and 34 months after lithotripsy, one after unsuccessful lithotripsy. CONCLUSION: Intra-corporeal lithotripsy is a valuable tool for the most complex cases of duct stones, and with an acceptable morbidity. The results of the two techniques are similar. Late biliary complications after intra-corporeal lithotripsy appear to be rare.

[Dilatation of the common bile duct without visible obstruction at endoscopic retrograde cholangiography. Description and development]. / Dilatation de la voie biliaire principale sans obstacle visible à la cholangiographie rétrograde endoscopique. Description et évolution.

The aim of this study was to specify the signs and course of patients with a dilated common bile duct without obstruction. We included patients with a dilated common bile duct of more than 12 mm on endoscopic retrograde cholangiography, and we excluded patients with stones, tumor or other visible obstruction. Two hundred and seven patients (8.4 p. 100 of endoscopic retrograde cholangiography) were included. One hundred and nineteen (57.5 p. 100) had undergone cholecystectomy. Sixty-five p. 100 of patients had signs suggesting biliary tract disease, and 78 p. 100 had biological signs of cholestasis. The size of the common bile duct was not different whether the patient had been cholecystectomized (16.2 +/- 0.3 mm.M +/- SEM) or not (16.2 +/- 0.4 mm). Forty-one patients in the non cholecystectomized group had gallbladder stones. Thus, 47 of our 207 patients (23 p. 100) had neither gallbladder stones nor previous cholecystectomy. Endoscopic retrograde cholangiography was completed by endoscopic sphincterotomy in 130 patients, either in the intent of not missing obstruction, or for therapeutic purposes. Follow-up more than one month after endoscopic retrograde cholangiography was available for 159 patients (77 p. 100). The median survival was 73 months. One hundred and ten patients (69 p. 100) were asymptomatic, 36 (23 p. 100) had atypical abdominal pain while 13 (8 p. 100) patients had episodes of biliary colic and/or fever and/or jaundice. During follow-up, an initially unrecognized obstacle was discovered in 8 patients: 5 common bile duct stones, 2 ampullary tumors and one pancreatic tumor.(ABSTRACT TRUNCATED AT 250 WORDS)

[Current results of endoscopic sphincterotomy for lithiasis of the common bile duct]. / Résultats actuels de la sphinctérotomie endoscopique pour lithiase de la voie biliaire principale.

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).

[Endoscopic drainage of pseudocysts of the pancreas. Study of 26 cases]. / Drainage endoscopique des pseudo-kystes du pancréas. Etude de 26 cas.

Endoscopic drainage of pancreatic pseudocysts has been proposed for several years as an alternative to surgical treatment. We report the results of 26 endoscopic cystostomies of pancreatic pseudocysts (13 cystoduodenostomies, 13 cystogastrostomies) performed in two specialized centres, from 1985 to 1991. The patients were divided into 3 groups (I, II, III) according to the pseudocysts' clinical presentation. The opening of the collection into digestive lumen was achieved in 22 cases; there were 3 puncture failures and 1 cystostomy was not performed because of a prior haemorrhagic puncture. Pain relief was obtained rapidly after cystodigestive drainage in 13 out of the 14 symptomatic patients. Three complications required surgery: 1 bleeding after cystoduodenostomy, 1 perforation and 1 peritonitis after cystogastrostomies. Two of them occurred after recutting a cystostomy. Two pseudocyst surinfections healed with antibiotic therapy. No deaths occurred due to the procedure. Among the 18 long-term followed-up patients (average = 33 months), 4 required surgery for persistence or relapse of pseudocysts. The results were excellent for the 14 other patients without any difference between cystoduodenostomies and cystogastrostomies, neither between the I, II and III groups. Each of the 5 cases with a digestive lumen-pseudocyst cavity thickness above 1 cm (measured on 20 CT scans) failed: 1 puncture failure, 3 complications, 1 relapse.

[Septicemias after endoscopic retrograde cholangiopancreatography. Risk factors and antibiotic prophylaxis]. / Scepticémies après cholangiopancréatographie rétrograde endoscopique. Facteurs de risque et antibioprophylaxie.

The infection following endoscopic retrograde cholangiopancreatography (ERCP) is one of the most severe complications. The aim of the present study was to assess the prevalence and the prognosis of this complication, to look for the risk factors and to define bacterial ecology in order to put forward the most appropriate antibiotherapy. Two thousand and ten patients were included in this study. Among these, 51 (2.5%) had a septic complication following ERCP. Endoscopy biliary drainage was complete in 24 cases, incomplete in 19 and lacking in 8. Transhepatic biliary drainage was carried out in 17 cases. Sixteen patients (31%) with tumor obstructions died within 30 days after ERCP. Four risk factors were isolated when comparing infected patients with other patients: the completeness of biliary obstruction (90 vs 48%, P < 0.001); multiple cannulation attempts (1.76 +/- 1.12 vs 1.25 +/- 0.70, P < 0.001); the malignant nature of the obstruction (80 vs 23%, P < 0.002) and the lack of satisfactory drainage following endoscopy (53 vs 23%, P = 0.009). Pseudomonas aeruginosa was the most frequently isolated species, both from blood cultures (30%) and bile samples (23%). The preventive therapy of septic complications following ERCP must include strict rules concerning the disinfection of endoscopic material.(ABSTRACT TRUNCATED AT 250 WORDS)

[Obstructive icterus in patients with hepatic tumor. Result of non-surgical biliary drainage]. / Ictère obstructif chez les malades ayant une tumeur hépatique. Résultat du drainage biliaire non chirurgical.

Seventeen patients with biliary obstruction and hepatic tumors were treated by endoscopic or percutaneous transhepatic drainage with an endoprothesis. There were 9 men and 8 women (mean age = 61 +/- 13 years). Four patients had primary hepatic carcinoma and 13 had hepatic metastases. Decrease of serum bilirubin of more than 75 percent was achieved in 12 of the patients (71 percent). The success rate was related to the level of the biliary obstacle and not to the importance of hepatic parenchymal involvement. Failure was significantly more frequent (p = 0.003) in patients with type III hilar strictures compared to the other patients with pedicular or type I and II hilar strictures. Cholangitis was the major complication (29 percent) and occurred only in the patients with type III hilar strictures. Mortality was 24 percent at 30 days. This rate was 57 percent in the group of patients with type III hilar strictures and significantly higher (p = 0.015) than other patients. Cumulative survival was better in patients with relief of jaundice than that observed in the other patients (p less than 0.01). Two patients with metastatic carcinoma of the breast treated by chemotherapy survived more than 20 months without jaundice. Analysis of these data indicates that in patients with hepatic tumors and obstructive jaundice, palliative treatment with endoprothesis can provide relief of jaundice and that prolonged survival may be observed in patients with chemosensible tumors.

[Secondary sclerosing cholangitis and chemo-embolization with lipiodol]. / Cholangite sclérosante secondaire et chimio-embolisation lipiodolée.

Two cases of sclerosing cholangitis after oily arterial chemoembolization are reported. In one patient angiocholitis with liver abscesses, in the other patient gradual cholestasis were the main clinical features. In both cases, endoscopic retrograde cholangiogram showed a stricture of the common hepatic bile duct and, in one case, irregularities of intrahepatic biliary tree. Histologic examination of the liver in the two patients pointed out the involvement of small bile ducts and arteriolar endarteritis obliterans. Ischaemia is likely to be the main mechanism of these two cases of sclerosing cholangitis as well as in those described after FUDR intra-arterial chemotherapy. The prevalence of sclerosing cholangitis after arterial oily chemoembolization is probably underestimated because of a non specific clinical presentation and need to be precise by further study.

[Extracorporeal lithotripsy in the treatment of common bile duct calculi]. / La lithotritie extracorporelle dans le traitement de la lithiase de la voie biliare principale.

Thirty-three patients with common bile duct stones which could not be extracted by routine endoscopic measures were treated with extracorporeal lithotripsy. Two electrohydraulic lithotripters were used: Dornier HM3 and Technomed Sonolith 3000 using fluoroscopy and ultrasonography, respectively, for stone localisation. Twenty-nine patients were treated with only one session and four patients in two sessions. Fragmentation of stones was obtained in 29 patients (88 p. 100) and complete bile duct clearence in 26 patients (79 p. 100). The fragments passes spontaneously through the papilla in 7 cases; in 19 cases complete removal of fragments was achieved with a Dormia basket (16 cases) or after mechanical lithotripsy (3 cases). There were no significant differences in successful fragmentation rates between the two lithotriters. No serious adverse effects or mortality were observed within the 30 days following treatment. In conclusion, extracorporeal lithotripsy is an effective and safe method for the treatment of bile duct stones when, after sphincterotomy, routine endoscopic measures have failed.

[Palliative treatment by endoprosthesis of icterus caused by distal biliary tumoral obstruction]. / Traitement palliatif par endoprothèse des ictères par obstacle tumoral biliaire sous-hilaire.

Between March 1982 and December 1987, 466 patients (256 women, 210 men, mean age 73 years) with tumor obstruction of the common bile duct were referred to our department. The causes of obstruction were carcinoma of the pancreas (298 patients), carcinoma of the ampulla of Vater (32 patients) and carcinoma of the common bile duct (136 patients). Endoscopical insertion of a biliary prosthesis was initially possible in 377 patients (81%). In case of failure, patients were referred to the radiologist for percutaneous drainage. Successful drainage was obtained in 58 patients with an overall success rate of 93% (435 patients). Endoscopic replacement was necessary in 170 cases for 114 patients and was successful in 155 (91%). Pruritus was relieved in 89% of the patients. Serum bilirubin levels decreased more than 75% after initial endoscopic endoprosthesis, repeated endoscopic endoprosthesis and percutaneous prosthesis insertion in 80%, 79%, and 62% of the patients, respectively. Short term complications of endoscopic endoprosthesis occurred in 28% of patients with a mortality rate of 8%. Percutaneous prosthesis complications occurred in 33% of patients with a mortality rate of 11%. In the long term, cholangitis was the main complication and occurred in 27% of patients with a delay of 103 +/- 105 days. Intestinal obstruction was observed in 7% of patients. The average life expectancy of endoscopic endoprosthesis and percutaneous prosthesis was 109 +/- 157 and 92 +/- 101 days, respectively. The average life expectancy of patients was 163 +/- 224 days.(ABSTRACT TRUNCATED AT 250 WORDS)

[Radiation-induced stricture of the papilla and the common bile duct: successful treatment with balloon dilation]. / Sténose radique de la papille et du cholédoque: succès de la dilatation au ballonnet.

Radiation-induced lesions of the bile ducts rarely occur and may be difficult to manage. We report the case of a 59-year old woman who developed radiation-induced stenosis of the papilla and the common bile duct 25 years after abdominal radiation therapy for abdominal non-Hodgkin's lymphoma. She presented with recurrent cholangitis and chronic cholestasis. Endoscopic results showed dilation of the intrahepatic bile ducts, radiation-induced inflammation and narrowing of the antrum and the duodenum, and stricture of the papilla and the last few millimeters of the common bile duct. The patient was treated with endoscopic balloon dilation. Forty-two months after endoscopic dilation, the patient remained asymptomatic with normal liver tests and no biliary dilation at ultrasound.

[Endoscopic sphincteroclasy for choledocholithiasis of the principal bile duct. Short-term results and follow-up]. / La sphinctéroclasie endoscopique pour lithiase de la voie biliaire principale. Résultats immédiats et à distance.

AIMS: The hydrostatic dilatation of the papilla of Vater, or sphincteroclasy, has been recently proposed as an alternative to endoscopic sphincterotomy. Our aim was to assess short term results and follow-up after sphincteroclasy for choledocholithiasis. METHODS: From August, 1994 to December, 1996, 52 patients were included for endoscopic therapy of choledocholithiasis (mean age 66 +/- 17 years). Patients were prospectively followed on the short term-period (24 h, 48 h and 30 days) and longer term after treatment (every 6 months) by clinical and biological controls. MAIN RESULTS: Forty-eight sphincteroclasies were performed successfully (92.3%). Thirty seven patients had a choledocolithiasis. Eleven were stone-free. Eight had undergone former gastric surgery and 8 had impaired coagulation test. Complete stone clearance was achieved in 98% of patients. Mild pancreatitis were observed in three patients (6.25%). Thirty-day mortality was nil. Long term follow-up (mean 21.4 +/- 7 months) revealed: 2 patients with cholecystitis 6 and 13 months after treatment, one of which was followed 8 months later by a fatal septic shock, and 3 patients with cholangitis, 2 of which in the same patient, 9, 12 and 24 months after sphincteroclasy. The global long term biliary complication rate was 8.4%, 4.2% of which were potentially related to the endoscopic procedure. CONCLUSION: Sphincteroclasy is an efficient procedure for the treatment of choledocholithiasis. Its short term results are similar to those of endoscopic sphincterotomy. Complications after 2 years appear to be scarce, but longer follow-up is required before routinely performing sphincteroclasy.
