Internal biliary stenting in orthotopic liver transplantation.

Biliary complications account for significant morbidity in orthotopic liver transplantation (OLT), with a reported incidence ranging from 6% to 47%, and many centers are reassessing the need and options available for stenting the biliary anastomosis. We report on our experience using a 6F Silastic, double-J, ureteral stent as an internal biliary stent in OLT. From October 15, 1995, to September 30, 1998, a total of 99 patients at our institution underwent 108 OLTs. Of these, 77 patients received an end-to-end choledochocholedochostomy over an internal stent. Three patients died within 1 week post-OLT, leaving 74 patients for evaluation (follow-up, 2 to 38 months). Stents were placed transanastomotic and transsphincteric at the time of OLT and secured with a dissolvable suture. At 4 to 6 weeks post-OLT, stents visible within the biliary tree on kidney, ureters, and bladder radiograph were removed endoscopically. Graft and patient survival rates were 92% and 96%, respectively. There were 12 biliary complications (18%): anastomotic leak in 6 patients (9%), anastomotic stricture in 5 patients (7.6%), and stent migration in 1 patient (1.5%). Thirty-two patients (43%) passed the biliary stent without intervention, whereas 42 patients (57%) underwent esophagogastro duodenoscopy (EGD) stent removal at 4 to 6 weeks without incident. Treatment of the complications included percutaneous drainage, endoscopic dilatation with stenting, and/or conversion to Roux-en-Y choledochojejunostomy. The use of the 6 F Silastic, double-J, ureteral stent provides a safe and effective means of stenting the biliary anastomosis in OLT. Major advantages to this method are that it: (1) is completely internal, (2) is biliary decompressive, (3) is radiopaque, (4) can be spontaneously passed, and (5) is easily accessible for EGD extraction.

[Surgical palliation for pancreatic cancer. The 25-year experience of a single reference centre].

BACKGROUND: In spite of dynamic development of modern diagnostic and therapeutic methods, the long-term results of surgical therapy in pancreatic cancer are still unsatisfying. The aim of this study was to analyse long-term results of surgical palliation for pancreatic cancer in a pancreatic surgery centre. METHODS: We performed a retrospective analysis of 418 patients who underwent non-resective, palliative procedures for pancreatic cancer between 1975 and 1999. In order to compare two consecutive periods of time, the patients were divided in 2 groups; group I treated from 1975 to 1990 (n = 204), and group II from 1991 to 1999 (n = 214). RESULTS: Of all patients qualified for surgery, 281 (67.2 %) underwent surgical bypass, 107 (25.6 %) laparotomy, and in 30 cases surgical intervention was limited to implantation of endoprosthesis. A significant tendency towards double (i. e. biliary and gastric) anastomosis was observed (32.3 % vs. 74.8 %; p < 0.01) in patients who underwent bypass procedures. The postoperative morbidity was 16.3 %. The postoperative mortality rate was 5.7 % and significantly (p < 0.01) decreased from 10.3 % (group I) to 1.4 % (group II). No differences neither in mortality nor morbidity related to the type of performed surgery were found. The mean time of hospital stay was 15.5 +/- 6.9 days and showed no differences related to the type of intervention. Jaundice or symptoms of gastric outlet obstruction were observed in 16 % of patients in the follow-up period and concomitantly performed biliary and gastric bypasses were associated with the lowest rate of the late gastrointestinal obstruction (4 %). The median survival time was 169 days and only 4 % of patients survived 12 months. The univariate analysis of prognostic factors showed that location and stage of the tumour, the type of surgical intervention and bypass procedure influenced 1-year survival. The multivariate analysis using Cox proportional hazard model proved that only stage and location of the tumour had independent prognostic value. CONCLUSION: Surgical palliation for pancreatic cancer can be performed with acceptable morbidity and mortality rates. For tumours located in the head and body of the pancreas combined biliary and gastric bypass should be preferred. For cancers located in the tail of the pancreas gastric bypass should be performed routinely. Because surgical palliation can prevent gastric outlet obstruction by gastroenterostomy, endoscopic biliary stenting should be only performed in patients with pancreatic head cancers and simultaneous evidence of distal metastases as well as in older patients with high comorbidity.

Spontaneous rupture of extrahepatic choledochal cyst: two pediatric cases and literature review.

Spontaneous rupture of extrahepatic choledochal cysts is very rare. Neonatal cases generally present with biliary ascites, and older children with acute abdomen. Although the cause is unclear, accumulation of protein plugs in an anomalous pancreaticobiliary junction, irritation of the cyst wall due to reflux of pancreatic juice, and weakness due to a developmental error such as common channel syndrome have all been suggested to play contributing roles. The treatment of choice is complete excision of the cyst and hepatico-jejunostomy. In newborns who are in a poor condition, the primary treatment should be simple peritoneal drainage.

Recurrence rate of anastomotic biliary strictures in patients who have had previous successful endoscopic therapy for anastomotic narrowing after orthotopic liver transplantation.

BACKGROUND AND STUDY AIMS: The development of anastomotic strictures is one of the most common complications of orthotopic liver transplantation (OLT) with choledochocholedochostomy anastomosis. Endoscopic therapy with balloon dilation and/or stent placement is an effective therapy. The aim of this study was to assess the recurrence rate of anastomotic strictures and the features that predict recurrence after previously successful endoscopic therapy. PATIENTS AND METHODS: We searched the endoscopic retrograde cholangiopancreatography (ERCP) database for all patients who had had an OLT who were undergoing ERCP. The study cohort consisted of post-OLT patients who had a recurrence of anastomotic stricture after initial resolution following a course of endoscopic therapy. RESULTS: A total of 916 OLT operations were performed during the study period from June 1994 to November 2004. Out of this group, 143 patients (15.6 %) were diagnosed with anastomotic stricture and underwent a total of 423 ERCPs for endoscopic treatment. Twelve patients who are still undergoing endoscopic therapy were excluded from the analysis. The technical success rate was 96.6 %, and the endoscopic therapy was successful in 82 % of patients; 18 % had a recurrence of cholestasis and ERCP revealed a recurrence of the anastomotic stricture that required intervention. The mean time of follow-up after stent removal was 28 months (range 1 - 114 months). The study did not reveal any clinical or endoscopic parameters that could predict recurrence, though the presence of a biliary leak at initial ERCP and a longer time to initial presentation were factors that showed a trend toward an increased likelihood of recurrence. CONCLUSIONS: Biliary strictures remain a common complication after OLT, and in nearly one in five patients these strictures recur after initially successful endoscopic therapy. There were no clinical or endoscopic parameters identified in this study that predicted recurrence. Further study is needed to determine what type of endoscopic therapy would minimize the risk of stricture recurrence.

Endoscopic treatment of the "sump syndrome" after choledochoduodenostomy: a new technique using an amplatzer septal occluder.

A 58-year-old male patient had been suffering for 35 years from recurrent cholangitis, biliary sludge and infection-induced stone formation after open cholecystectomy because of empyema of the gallbladder and severe acute and delayed postoperative complications. The pathophysiological origin of this chronic "sump syndrome" was a choledochoduodenostomy which had been performed prophylactically at the time of the initial operation. The patient agreed to an experimental treatment option with use of an Amplatzer atrial-septal defect (ASD) occluder for closure of the symptomatic choledochoduodenal fistula. The double-disc occluder was introduced through a 9 French diameter and 90 cm long sheath side to side with a duodenoscope. Under endoscopic and fluoroscopic guidance the distal disc was opened in the common bile duct, then retracted against the fistula's orifice. Subsequently, the proximal disc was unfolded in the duodenum, while the 9 mm waist between the two discs filled and shut the fistula. No side effects or complications were detected. The day after the procedure, endoscopic evaluation demonstrated the correct position of the occluder and closure of the fistula. Over a period of 12 months, repeated assessments did not reveal any major problems. The patient felt a significant subjective improvement. The use of a self-expanding occluder system for closure of a choledochoduoenotomy complicated by chronic and symptomatic duodenocholedochal reflux might therefore represent an enrichment of the equipment of interventional endoscopists.

Endoscopic therapy of the sump syndrome.

Seventeen consecutive patients with the sump syndrome were treated at the Middlesex Hospital between November 1983 and December 1987. Fifteen were treated primarily by endoscopic sphincterotomy and two primarily by resective surgery because of coincident severe painful chronic pancreatitis. Endoscopic sump clearance was successful in thirteen out of fifteen cases (87%) with no morbidity or mortality. The two endoscopic failures were managed surgically. Follow-up (mean 18 months; range 2-48 months) has shown complete resolution of symptoms in twelve (71%), with mild or moderate ongoing symptoms in the remaining five. All patients with ongoing symptoms after sump clearance had abnormal retrograde pancreatograms at the time of ERCP. Endoscopic sphincterotomy is the treatment of choice for the sump syndrome, with the possible exception of patients with coincident painful severe chronic pancreatitis, who may require pancreatic resection. Indeed, the sump may be a factor in the development and perpetuation of an obstructive chronic pancreatitis, and a trial of endoscopic clearance may be indicated even in these patients. The sump syndrome should no longer be regarded as a major long-term disadvantage of side-to-side biliary bypass, provided that the condition is considered early in those with compatible symptoms after biliary bypass, and appropriate investigation and treatment is instigated.

[MRI-assisted bile duct drainage: evaluation of passive catheter imaging in an animal model].

PURPOSE: To investigate interactive MR-assisted bile duct drainage in pigs with the passive visualization technique using near real-time imaging. METHODS: 8 bile duct drainages were placed in an open low-field MR system (0.2 Tesla) in 4 pigs with surgically induced cholestasis. After planning the intervention with magnetic resonance cholangiography (MRC), both the puncture and catheter placement were interactively guided using a fast T2-weighted true FISP sequence. RESULTS: MRC enabled interventional planning in all puncture attempts. Punctures were unproblematic in all attempts, the bile ducts were punctured 6 times after the first and twice after the second attempt. Placement of the passively visible catheter was successful in all animals. The applied sequence enables interactive fluoroscopy-like positioning of the devices. CONCLUSION: The procedure introduced here enables reliable and fast placement of a bile duct drainage in an animal model using a low-field MR system.

Rupture of the duodenum with avulsion of the papilla of Vater due to blunt trauma in a child, and review of the literature.

Duodenal rupture with avulsion of the papilla of Vater is an uncommon injury due to blunt abdominal trauma in children. This report describes a 9-year-old boy who sustained this injury and was treated successfully two days delayed by a Roux-en-Y choledocho-pancreaticojejunostomy and temporary implantation of a zipper for abdominal wall closure. The rarity of this complex injury and its initial presentation as a posttraumatic pancreatitis warrant its description. A review of the literature, modes of diagnosis and surgical technique for repair are described.

Late results in the management of choledochal cysts.

From 1971 to 1990, 18 children were surgically managed for choledochal cysts at two Berlin pediatric surgical units. Eight patients underwent an internal drainage procedure, eight a Roux-en-Y hepaticojejunostomy and one a choledochoplasty. The children were followed-up 2 to 20 years later (median: 8.4 years). Three children died in the early postoperative period, but the immediate postoperative course was uneventful in all other cases. Later, five patients suffered from recurrent gastrointestinal disease, cholangitis and pancreatitis and, in two cases, from progressive liver fibrosis. Four of the five patients with symptoms had undergone internal drainage procedures; one developed cholangitis after a hepaticojejunostomy. In one case of internal drainage, the anastomosis was transformed into a hepaticojejunostomy. No patient had cancer.

[Choledochal cyst. The clinical picture, diagnosis and therapy].

A 21-year-old woman who for more than one year had had epigastric pain which was unrelated to food and radiated belt-like, was found to have a marked increase in gamma-GT, slightly elevated phosphatase activity, and increased erythrocyte sedimentation rate. The diagnosis of choledochal cyst, type Ia, was confirmed by sonography, endoscopic retrograde pancreatography and intravenous cholangiography. A choledochocystojejunostomy with a Y-Roux anastomosis was constructed to stop the cholestasis and prevent complications. The patient became symptom-free after the operation.

Biliary tract complications after orthotopic liver transplantation with choledochocholedochostomy anastomosis: endoscopic findings and results of therapy.

BACKGROUND: Biliary tract complications are a continuing source of morbidity after orthotopic liver transplantation. This is a retrospective examination of experience with ERCP in patients with biliary tract complications after orthotopic liver transplantation to determine type and frequency of complications and outcome after endoscopic therapy. METHODS: From May 1988 to August 1999, orthotopic liver transplantation was performed 408 times; 4 additional patients who underwent orthotopic liver transplantation at another hospital were also followed. The records of 367 patients who underwent choledochocholedochostomy were reviewed. Of these, 121 underwent 325 ERCPs; 226 ERCPs were performed because of acute problems (typically cholestasis with or without cholangitis), and 99 were for reevaluation of the bile duct, stent change, or stent removal. Three patients underwent ERCP because of pancreatic problems. RESULTS: A biliary complication was identified in 24.5% of patients (90 of 367) and more than 1 complication in 32%. At ERCP, 37 patients (30.5%) had biliary stones; 9 further patients (7.4%) had only sludge. Stones were completely cleared at the initial or a subsequent ERCP. Strictures were found in 55 patients (45.5%), either at the anastomosis (n = 43) or at another site(s) in the donor duct (n = 12). Balloon or bougie dilation followed by stent insertion was performed in 54 patients. Endoscopic therapy was successful in 91% of patients with biliary strictures. A biliary leak/fistulae was found in 22 patients (18.1%) and endoscopic therapy, when attempted, was successful in all. Eight patients had possible sphincter of Oddi dysfunction based on dilated recipient and donor ducts together with elevated liver enzymes. After sphincterotomy, the liver enzymes returned to normal in only one of these patients. Three patients had blood clots in the biliary tree. CONCLUSION: When biliary tract complications are suspected after orthotopic liver transplantation, ERCP identifies biliary abnormalities if present and offers multiple therapeutic options. Endoscopic therapy is usually successful but multiple procedures are often necessary, especially when treating strictures.

Biliary drainage by endoscopic choledochoduodenal fistulotomy in patients with papillary carcinoma.

BACKGROUND: There are few reports of endoscopic choledochoduodenal fistulotomy (endoscopic fistulotomy) in patients with papillary carcinoma by using a needle-knife. METHODS: Among 35 patients with papillary carcinoma requiring biliary drainage, 14 with a suprapapillary bulge underwent endoscopic fistulotomy alone or with widening of the fistula by using a standard sphincterotome or dilation balloon catheter. OBSERVATIONS: Transfistula bile duct cannulation was successful on the first attempt in 13 of 14 patients (93%) and temporary biliary drainage through the fistula was successfully established in all 13 patients. The single complication was minor bleeding (7%) in 1 patient. In 6 patients with biliary obstruction who were not operative candidates, endoscopic fistulotomy was used for palliation, and all remained asymptomatic for a mean period of 3.2 months. CONCLUSIONS: Endoscopic fistulotomy is an effective, relatively safe biliary drainage procedure. It should be considered in selected patients with bile duct obstruction caused by papillary carcinoma and a suprapapillary bulge caused by the dilated bile duct.
