RESUMO

BACKGROUND: Strictures and concrements are the most common biliary complications following liver transplantation. Endoscopic treatment might not lead to a definitive cure in all patients, especially in strictures involving the biliary bifurcation. The aim of this study was to determine the efficacy and the long-term outcome of hepaticojejunostomy (HJS) for post-transplant biliary tract obstruction. MATERIAL AND METHODS: Thirty-seven patients were retrospectively studied for resolving of cholestasis and the incidence of recurring biliary obstruction. RESULTS: Surgery was performed because of anastomotic strictures in 11, ischemic strictures at the donor common bile duct in seven, strictures involving the bile duct bifurcation in 10, hepatolithiasis without strictures in one and biliary cast formation diagnosed by endoscopic retrograde cholangiography or T-tube cholangiography in eight patients. Cholestasis instantly improved in 82% of the patients. After a long-term follow-up of median 33 months (range 3-149), 28 of the patients (76%) required no further intervention for recurring biliary obstruction following HJS. Anastomotic strictures were observed in six (16%), recurring biliary concrements in two patients (5%). CONCLUSION: HJS did prevent recurrent biliary obstruction in the majority of the patients. We therefore recommend early HJS for complicated post-transplant biliary tract obstruction not treatable by a limited number of endoscopic interventions.

RESUMO

BACKGROUND: In January 1999 a new kidney allocation program was launched by the Eurotransplant Foundation, the 'Eurotransplant Senior Program' (ESP). Cadaveric donors above the age of 65 yr are allocated to kidney transplant recipients of the same age group. METHODS: Using a single-center database, 91 patients who underwent first renal transplantation at the age of 65 yr and older in the years 1999-2002 were identified. Fifty-six patients were transplanted through ESP allocation (study group) and 35 patients (control group) via normal Eurotransplant Kidney Allocation System (ETKAS) procedure. RESULTS: Age, sex and comorbid conditions did not differ by group. The rate of acute rejection episodes, primary non-function, delayed graft function, perioperative mortality did not differ by group. Serum creatinine was significantly lower in the ETKAS group (1.3 vs. 1.9 mg/dL; p=0.015) from six months after the transplantation on. Overall graft survival at six yr was 56% in the ETKAS group and 52% in the ESP group. With 73% in the ETKAS group and 71% in the ESP group, cumulative patient survival according to the Kaplan-Meier estimation was not statistically different at five yr. CONCLUSIONS: We did not find a relevant difference in the outcome between young and old kidney transplants in old recipients after this long observation period.

RESUMO

A series of 74 consecutive patients (48 women, 26 men) were operated for abdominal hydatid disease between June 1949 and December 1995. The patients ranged in age from 15 to 81 years (median 49 years). In 69 cases only the liver was affected; two patients had concomitant extrahepatic disease (one spleen, one spleen and lung), and 3 had cysts in the spleen only. Cysts were multiple in 11 patients and calcified in 24. Conservative surgical procedures were used for 22 cysts in 20 patients [open partial (n = 3), open total (n = 6), closed total cystectomy (n = 9), marsupialization (n = 2), drainage (n = 2)] and radical surgical procedures for 72 cysts in 54 patients [pericystectomy (n = 41), wedge liver resection or hemihepatectomy (n = 25), splenectomy (n = 5), radical resection of a lung cyst (n = 1)]. Altogether 37 patients (50%) were given perioperative antihelmintic chemotherapy with mebendazole (18 patients) or albendazole (19 patients). Operative mortality rates were 5.0% after conservative surgery and 1.8% after radical surgery. Morbidity rates were 25.0% following conservative surgery and 24.1% following radical surgery. Antihelmintic therapy was well tolerated by all but five patients. All side effects were entirely reversible. Among the 74 patients, 60 (81.0%) were available for long-term follow-up (median 7.2 years; range 2.0-47.0 years). Recurrence of disease was seen in 9 of 60 patients at an interval of 3 months to 20 years from the first operation. The rate of recurrence was significantly lower after radical surgical procedures (p = 0.03) and after closed removal of the cyst (p = 0.04).

RESUMO

Acute hepatic failure is characterized by jaundice and hepatic encephalopathy within eight weeks after the onset of disease. Although acute hepatic failure is a rare occurrence, its rapid progression and high mortality (50 to 90%, depending on the etiology of disease) necessitate immediate intervention. In the absence of causal therapy, orthotopic liver transplantation is currently the only definitive and effective means of treating acute hepatic failure in Europe, acute hepatic failure accounts for 11% of all liver transplantations. At the University department of transplantation surgery in Vienna a total of 27 patients with acute hepatic failure underwent 31 liver transplantations in the last 10 years (1.1.1987 to 31.12.1996). Twenty (74%) of the 27 patients survived the acute event and were discharged from hospital in good general condition after a median postoperative stay of 25 days (range 14-81 days). Seven patients (26%) died between the first and 34th postoperative day (median 26 days) in the intensive care unit, although all potential modern options of intensive care and surgery were used. The causes of death were irreversible cerebral edema (n = 3), multiple organ failure due to bacterial sepsis (n = 3) and uncontrollable haemolysis (n = 1). With a 3-year graft survival rate of 70% the 3-year patient survival rate was 74%. A retrospective analysis of our patients revealed that the postoperative graft function and the incidence of re-transplantation were significant prognostic factors (p < 0.05) for survival following orthotopic liver transplantation for acute hepatic failure. In the absence of further prognostically relevant preoperative indices and in consideration of the potentially fulminant progression of disease, we strongly recommend that any patient, in whom acute hepatic failure is suspected, is immediately transferred to a specialized center with experience both in the conservative treatment of acute hepatic failure and emergency liver transplantation.

RESUMO

Post-transplant lymphoceles (LC) may lead to impaired graft function. Treatment modalities include fine-needle aspiration, percutaneous drainage, and surgical internal drainage. Recently, laparoscopic fenestration has been performed with good results, but experience is still limited. Between January 1991 and August 1996, 919 kidney transplantations were performed in 876 patients at our department. There were 745 first, 133 second, 30 third, 9 fourth, and 2 fifth operations. Sixty-three symptomatic LCs were detected in 62 patients (6.8%) after 39 +/- 31 days. In 44% of the cases, graft function was impaired; in 29% hydronephrosis was documented and in 6% infection of the LC. Forty-five of the 62 patients with LC (73%) had histologically proven rejection. Thirty-five of the 63 LCs were drained percutaneously, 20 LCs were internally drained by open surgery, and 8 LCs were drained by laparoscopy. In 14 of the 47 patients (30%) with primary percutaneous drainage, LC recurred; infection occurred in 17%. Twelve of these patients underwent surgery. One surgical redrainage was necessary after open fenestration. No conversion or complication was noted in the laparoscopy group. We conclude that surgery for post-transplant lymphoceles is safe and effective. We favor the laparoscopic technique in selected patients.

RESUMO

BACKGROUND: As significantly more patients die of infection than of rejection after liver transplantation, we have to conclude that overimmunosuppression is common. Our analysis was performed to investigate underlying disease as an appropriate parameter for individually reduced immunosuppression. DESIGN: A consecutive series of patients receiving primary liver transplantation was analyzed with regard to acute rejection. SETTING: Department of transplantation surgery in a university hospital. PATIENTS AND METHODS: From 1988 to 1995, 252 patients received liver transplantation for posthepatitic cirrhosis, alcoholic cirrhosis, cholestatic disease, or hepatoma and were analyzed in a univariate and multivariate manner. MAIN OUTCOME MEASURE: The influence of various underlying diseases on the incidence of acute rejection. RESULTS: The estimated risk for freedom from acute rejection and analysis of cumulative rates of acute rejection stratified by group showed significant differences between the groups, except for alcoholic and posthepatitic cirrhosis. Severity of acute rejection episodes, as assessed by the need for rescue therapy, was similar in both univariate analysis and cumulative rates for alcoholic and posthepatitic cirrhosis. As expected, patients with cholestatic disease exhibited a significantly increased requirement for rescue therapy. For patients with hepatoma, a low incidence of initial and a high rate of repeated rescue therapy were observed. The varying immunological behavior within this group may have influenced both expansion of the tumor and severity of acute rejection. Multivariate analysis of potential risk factors identified underlying disease as a variable of independent prognostic significance for acute rejection and the need to receive rescue therapy. CONCLUSION: These results indicate the importance of taking the original disease into consideration where immunosuppressive therapy is concerned.

RESUMO

The study examined lymphokine-activated killer cell (LAK) and natural killer (NK) cell activity in breast cancer patients prior to surgery as compared to effector cell lysis in patients with non-malignant breast tumors, further in connection with lifetime diagnosis of major depression, severity of current depression, anxiety and coping styles. Follow up studies covered a period of 6 and 12 months. Prior to surgery, life time diagnosis of major depressive disorder, trait anxiety and coping styles did not discriminate patients as far as effector cell lysis is concerned. LAK activity but not NK activity was reduced in patients with actual depressive symptoms (P < 0.01) and high state anxiety (P < 0.05). These findings support the hypothesis that LAK activity is a state marker of actually existing depression and anxiety prior to surgery. Affective rather than coping measures showed significant differences in LAK activity. For LAK activity, 1 year after surgery the only predicting factors were Tamoxifen therapy and chemotherapy.

RESUMO

Patients suffering from metastatic breast cancer and recurrent fever were investigated for viral reactivation or new viral infection as a possible cause of these febrile episodes. Three groups of patients were included in the study: (a) patients under adjuvant chemotherapy with cyclophosphamide, methotrexate and fluoruracil, (b) patients with stable metastatic disease treated with cyclophosphamide, fluoruracil and Adriamycin or mitoxantrone and (c) patients with progressive metastatic disease who also received the latter treatment. During the time of observation, patients under adjuvant chemotherapy did not present with fever or asymptomatic viral reactivation or bacterial infections at all. Out of 7 patients with stable disease, 2 had bacterial infections that coincided with the leukocyte nadir, and 1 presented with asymptomatic reactivation of cytomegalovirus. In contrast, fever in 9 of 11 patients with progressive disease was associated with a reactivation of herpes simplex virus (HSV) and in 3 of them with a consecutive reactivation of varicella zoster virus (VZV). The increase in complement-fixing anti-HSV or anti-VZV antibodies occurred in close association with a rise of the respective preexisting antibodies of the IgG class. In addition, HSV-infected cells were recovered from the urine of 7 patients with progressive disease further corroborating the serological data. Incidentally, natural killer cell activity, which has been postulated to be connected with the defense against viral infections, was found to be significantly lower in the group of patients with progressive disease, as compared to the group of patients under adjuvant chemotherapy (P less than 0.05) or to the group of patients with stable disease (P less than 0.05). We conclude that unexplained fever in patients with progressive metastatic breast cancer may result from viral reactivation.

RESUMO

The diagnostic value of mucin-like carcinoma-associated antigen (MCA) was compared to that of carcinoembryonic antigen (CEA) and/or CA 15.3 in patients with breast cancer. A total of 368 patients with breast cancer were studied, of whom 253 were free of metastases, whereas 94 had either skeletal or visceral metastases or diffuse metastatic disease. The diagnostic sensitivity of MCA proved to be comparable to that of CA 15.3 and superior to that of CEA in patients with metastatic breast cancer. In contrast, the specificity of MCA was superior to that of CA 15.3. Finally, the diagnostic sensitivity of each of the tested tumour markers, i.e. MCA, CEA and CA 15.3, could be improved by their combined use. We conclude that MCA, either alone or in combination with CA 15.3 and CEA, can improve the monitoring of disease progression in patients with metastatic breast cancer.

RESUMO

In order to determine the incidence and significance of CMV infected cells within human renal allograft biopsies 100 transplant biopsies were examined for the presence of CMV DNA within the renal tissue specimens using the in situ hybridization technique. In 41 cases CMV infected cells were predominantly found within proximal tubular epithelial cells, although typical nuclear inclusion ("owl eyes") were absent. In only one case was CMV detected within a few glomerular cells. The presence of CMV infected cells within allograft biopsies does not correlate with active CMV infection of the patients at the time of biopsy. There are no significant differences in the distribution of primary and secondary CMV infections between patients with positive and negative biopsy findings. No significant differences as to the histological alterations between CMV infected and non-infected biopsies could be found. The data give evidence that the renal allograft is more often affected by CMV than is generally appreciated. The in situ hybridization technique may be useful for the fast detection of latently CMV infected cells in renal transplants and thus may influence the choice of therapeutic steps early after transplantation. Furthermore, it may facilitate the diagnosis of interstitial nephritis due to virus infection if typical nuclear inclusions in routinely stained tissue sections are absent.
