Bronchobiliary fistula is a serious complication of echinococcosis of the liver. Surgical and endoscopic treatments have been used successfully in the management of bronchobiliary fistula due to hepatic hydatid cysts. However, very little information exists on the management of bronchobiliary fistula due to alveolar hydatid disease. We report here the efficacy of various potential therapies in three cases.
BACKGROUND: To analyze the diagnosis and the surgical treatment of intrabiliary ruptured hydatid disease of the liver. METHODS: Between 1990 and 1995, 263 patients with hydatid cysts of the liver underwent surgery in a university hospital. Twenty-five (9.43%) patients with intrabiliary rupture of hepatic hydatid cyst were retrospectively reviewed. RESULTS: Diagnosis was principally made using ultrasonography and computed tomography scanning and was confirmed by the findings of other tests. In 12 patients (48%) partial cystectomy with primary closure; 5 patients (20%) partial cystectomy with drainage; 5 patients (20%) cystotomy with drainage; 3 patients (12%) left hepatic resection (atypic, segmentary or lobar) was performed. Omentoplasty was performed in 6 patients. The common bile duct was explored in all patients and it was drained by a T-tube in 22 patients, and by a choledochoduodenostomy in 3 others. The average postoperative hospitalization time was 8.3 and 22.5 days in patients treated with choledochoduodenostomy and T-tube drainage respectively. Cholecystectomy was performed in 18 patients. Complications were seen in 4 patients (16%) with 1 pleural effusion and 3 wound infections. There was only 1 death (4%) due to duodenal peptic ulcus perforation with intrabiliary ruptured hydatid cyst. CONCLUSION: This study indicates that T-tube drainage and choledochoduodenostomy in intrabiliary ruptured hydatid cysts are effective procedures with low morbidity and mortality rates.
Interferon-alpha (IFN) and ursodeoxycholic acid (UDCA) combined have a controversial role in the treatment of chronic type C hepatitis. We studied the long-term efficacy of both drugs alone or in combination. In a three-year period, 108 patients were randomized into three treatment arms: (1) IFN alone 3 MU three times a week (N = 49), (2) IFN 3 MU three times a week + UDCA 250 mg twice a day (N = 45), and (3) UDCA alone 250 mg twice a day (N = 14). Response was defined as complete normalization of serum ALT. For the responders at the end of six months, the treatment was run to 12 months. Nonresponders (NRs) of the first group were crossed over to combination and NRs of the combination received 6 MU three times a week IFN+UDCA for the next six months. The enrollment to the UDCA alone arm was stopped early, since only 1/14 normalized serum ALT at the end of third month. However, 12/14 completed six months and 11 NRs received IFN 3 MU three times a week alone for the next six months. Twelve discontinued treatment due to side effects. Responders were followed-up untreated for 18 months. Sustained response (SR) was defined as persistence of normal serum ALT levels in this period. At the end of six months, 22/45 (48%) from the IFN-alone and 23/39 (58%) from the combination group responded. Twenty NRs from former and 15 of latter group were crossed over. While none of the 20 from the IFN-alone group responded to the combination, 1/15 NRs of the combination group responded to dose escalation. SR was achieved in 9/45 (20%) of the IFN alone and 7/39 (18%) of the combination group. The mean time form the end of the treatment to the relapse was not different between the groups. Five of 11 UDCA NRs responded to IFN with SR in 2. It was concluded that UDCA as a single agent is ineffective in achieving response in the treatment of chronic type C hepatitis. Combined with IFN, it increases response rate insignificantly although this is not sustained.
Rare causes of liver dysfunction in pregnancy may pose a challenge to the consulting gastroenterologist or hepatologist from both the diagnostic and therapeutic standpoints. We describe here liver function abnormalities in a case of hyperreactio luteinalis with light and electron microscopic findings.
A 33-year-old woman with autoimmune hepatitis developed resistance to prednisolone-azathioprine treatment. A switch to cyclosporin A resulted in immediate remission which was maintained for more than one year. No significant side effect was encountered. Cyclosporin A may be an alternative treatment for patients with autoimmune hepatitis who are resistant to conventional treatment.
The ability of erythrocytes to resist lipid peroxidation may be a useful marker of antioxidant status in alcoholic patients, in whom depletion of dietary antioxidants may combine with increased production of free radicals to produce liver damage. There are conflicting reports, however, on the resistance of erythrocytes from alcoholic patients to lipid peroxidation. This study examined the relation between the degree of alcohol induced liver disease and the resistance of erythrocytes to chemically induced lipid peroxidation, measuring lipid peroxidation as malondialdehyde production. Erythrocytes from alcoholic patients with Child's C cirrhosis had significantly increased resistance to lipid peroxidation compared with both controls (p < 0.001) and alcoholic patients with moderate liver disease (p < 0.001). There was no difference between alcoholic patients with moderate liver disease and controls. Increased resistance to free radical initiated lipid peroxidation in alcoholic patients is related to liver damage rather than to alcohol abuse alone. This could arise from changes in the lipid composition of the erythrocyte membranes resulting from abnormal liver function. Tests of antioxidant status based upon the resistance of erythrocytes to free radical stress in vitro may therefore be flawed when such changes in membrane lipid composition can occur.

Thirty-six patients with intrabiliary rupture of hepatic echinococcal cysts were managed between 1974 and 1993. Clinical findings, skin tests, serologic tests, and imaging techniques were used to establish the diagnosis. Twenty-five (69.4%) patients had pain, 24 (66.6%) jaundice, 22 (61.1%) fever, 20 (55.5%) chills, 10 (27.7%) malaise, and 7 (19.4%) other symptoms as the major causes of admission. All patients underwent choledochotomy and T-tube drainage. Treatment directed to the cyst was cystectomy and capittonage, cystectomy and drainage, and partial hepatectomy in 22, 12, and 2 patients, respectively. Omentoplasty was added to the treatment in 10 patients. Seven (19.4%) patients had complications. The period of hospitalization for patients with and without complications was 34.6 +/- 18.1 and 15.1 +/- 2.7, days, respectively. This study indicates that better results are obtained in patients with cystic lesions of the liver by avoiding percutaneous puncture or biopsy, the early use of ultrasonography and computed tomography, evacuation of the cyst together with its germinative membrane and the involved biliary tract under adequate care to avoid spillage into the peritoneal cavity, treating the remaining cavity according to its location, size, and the presence of infection, and decreasing the pressure in the biliary tract by T-tube drainage.
Small bowel perforation is a rare complication of miliary tuberculosis. We report the case of a 21-year old patient who developed a small bowel perforation 70 days after the initiation of adequate tuberculosis treatment. We also present a review of the literature.
