Dilatation of biliary strictures through the afferent limb of a Roux-en-Y choledochojejunostomy in patients with sclerosing cholangitis.

Repeated dilatation of biliary strictures in patients with sclerosing cholangitis through a subcutaneously placed afferent limb of a choledochojejunostomy is technically feasible and safe. This study is a prospective 15-year evaluation of 36 patients treated by repeat dilatation through this jejunal limb. There was one operative death and one major complication of dilatation. The 5-year survival of all patients was 74%. If patients with cirrhosis or unproven cholangiocarcinoma at the time of operation are not included, the 5-year survival is 86%. The 15-year survival of all patients was 30%; it was 64% if those with cirrhosis and unproven cholangiocarcinoma at the time of operation are not included. Six patients are presently alive with an average survival of 159 months. The study suggests that a combination of repeated dilatations combined with transplantation is the approach of choice in selected patients.

A phase I study of chemoembolization with cisplatin, thiotepa, and lipiodol for primary and metastatic liver cancer.

Thirty patients with primary hepatocellular carcinoma or liver metastases were entered into a program of chemoembolization with cisplatin, lipiodol, and escalating doses of thiotepa. Doses of cisplatin were 100/m2, and thiotepa doses ranged from 9 mg/m2 to 24 mg/m2. Two of three patients with ocular melanoma had partial responses in the liver metastases for 3+ and 16 months. In patients with either hepatocellular carcinoma (15 patients) or primary cholangiocarcinoma of the liver (three patients), there were two partial responses, for 22 and 33 months. Five patients had minor responses: four with a 40% reduction in tumor and one with a mixed response. There were four early deaths, which involved sepsis in two patients, respiratory failure in one, and acute myocardial infarction in one. Otherwise, toxicity was tolerable and reversible and included abdominal pain and transient elevation of serum creatinine, bilirubin, and transaminases. Less common toxicities included ototoxicity and peripheral neuropathy. Chemoembolization of the liver with cisplatin, thiotepa, and lipiodol can produce responses, but toxicity can be significant. The recommended starting phase II dose for future studies is thiotepa 24 mg/m2 and cisplatin 100 mg/m2.

Percutaneous dilatation of biliary strictures through the afferent limb of a modified Roux-en-Y choledochojejunostomy or hepaticojejunostomy.

BACKGROUND: This report is a 13-year prospective evaluation of percutaneous balloon dilatation of benign biliary strictures through the subcutaneous or subfascially positioned afferent limb of a choledocho or hepaticojejunostomy in 30 patients. DATA SOURCE: Twenty-seven strictures developed after a common duct injury sustained at the time of cholecystectomy, two after hepatectomy reconstruction for trauma and one following a gastrectomy. Twelve injuries (40%) were recognized at operation. Of the 18 patients where the injury was unrecognized at the time of operation, 8 had not been reoperated at the time of referral, 7 had late repairs by the referring physician, and 3 had late repairs at our institution. The follow-up is 1 to 13 years. RESULTS: There has been 1 late death and 6 patients are lost alive. The jejunal-limb was accessed 50 times with two minor and no major complications. There have been two parajejunal hernia repairs, but there have not been any reoperations for recurrent biliary strictures. CONCLUSIONS: Benign biliary strictures can be effectively managed by repeat balloon dilatations thru the afferent limb of a choledocho or hepaticojejunostomy, thus eliminating the need for repeat surgical interventions.

Donor biliary variations: an overlooked problem?

Documented causes of biliary complications following orthotopic liver transplantation have been related to technical imperfections or insufficient arterial supply. Although anatomical variations of the extrahepatic biliary system are not infrequent, neither their incidence, surgical management nor possible association with complications have been reported in liver transplantation. At our institution, the global incidence of biliary complications following 357 consecutive liver transplants performed in 324 patients over a 2-yr period was 15.4% (55/357). Anomalous donor extrahepatic ducts were verified in 10 cases (2.8%) and they were recognized intraoperatively, prior to biliary reconstruction, in 7 cases. Technical complications occurred in 1 of these 7 and in 3 other cases where the anomalous ducts were not identified until later in the postoperative period when serious clinical problems ensued. We herein present a description of these 10 cases, with reference to the techniques employed to manage the anatomical anomalies and to treat complications. As in any hepatobiliary procedure, awareness of possible variations of the extrahepatic biliary system, intraoperative identification of the anomalous ducts and appropriate tailoring of the surgical technique are advisable in order to avoid serious postoperative complications in liver transplantation.

Balloon dilatation through the subcutaneously placed afferent limb of a hepaticojejunostomy in patients with resected Klatskin tumors.

It is generally conceded that palliation for proximal bile duct tumors (Klatskin) is exceptional if obstruction and the resultant infections can be prevented. Our experience with balloon dilatations thru the subcutaneously placed afferent limb of a choledocho or hepatico jejunostomy in patients with benign strictures suggests that this approach will be effective in patients with malignancies and thus provide long-term control of the obstruction without the need for external tubes. This is a report on one patient who, following a resected Klatskin tumor with positive margins, was treated with transhepatic internal external stents and was converted to a subcutaneous limb following numerous bouts of cholangitis. A schedule for repeat dilatations thru the jejunal limb was established. The patient has remained afebrile with a normal bilirubin and a moderately elevated alkaline phosphatase. Recurrent tumors or postirradiation strictures in patients with resected Klatskin tumors can be effectively controlled by repeated balloon dilatation without the need for external stents.
